[Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

So there i was just happily browsing the web when i spots this...

A 4.1 GHz Dual Core at £79.95 - Can it be True?
http://tomshardware.co.uk/2006/05/10..._uk/page2.html

So as im a tight Scottish lad who wants to get everything for next to nothing this was irresistable as i need to upgrade my PC.

So to quote from the article above and explain what im about to do:-

How could i refuse... So off to Komplett i went and bought one of these bundles. (£216 quid inc delivery)

Essentially its a:-

Intel Pentium D 805 2.66GHz Socket LGA775, 4MB, BOXED w/fan
ABIT AL8-V, Intel 945P, Socket-775, ATX, SATAII, Dual-DDR2, GbLAN, PCI-Ex16
TwinMOS DDR2 PC4300 1024MB Dual Pack KIT w/two matched DDR2 PC4300 512MB CL4

So as this is to upgrade my current PC for a new one for as next to nothing as possible (My 2500+ was getting long in the tooth) i need to also upgrade my GFX card because my overclocked X800 Pro, which has been flashed to an X800XT and had all its pipes opened, forced to 500/500 - is AGP. :mad:

So's anyway - Ebay - equivalent PCI card 60 quid or theres about.

Now cooling - i already have water cooling so all i need to do is change the waterblock for the CPU to a compatible one for the 775 chipset. The Thermaltake CPU Water Block, CL-W0010, (subject to change at time of writing) seems to fit the bill at 25 quid (inc delivery).

So thats a top 'o' the range kick ass mofo PC for less than 300 quid IF i can pull this off.

I already have a 500w enermax supply so that should be Ok - and i can flog my existing stuff (like my AGP card and memory) on Ebay so i might get this back down to around 200 quid for the upgrade.

An interesting project don't you think?

Assuming it works... :D I will keep you uptodate on this one.

Re: Im going for it - Monster O/C on Pentium D 805
 

It will work. Seen it done a thousand times (well, maybe not a thouasand, but a substantial amount) Alot of people have been doing things like this, and it seems that the Conroe will do exactly the same, only, it will be alot more powerful to begin with.

I've got a Celeron D 335 upto 3.6Ghz, and i've seen 5Ghz frm a frenchie.

Good luck with this project, and i might be interested in that GFX card of yours, how much you asking?

---------- Post added at 18:09 ---------- Previous post was at 18:05 ----------

By the way, i'll happily bench against you when you're done for some comparisons if need be :)

Re: Im going for it - Monster O/C on Pentium D 805
 

Not sure mate, a quick look on Ebay shows prices from 110 (non VIVO) to 140 (VIVO flashed as i have) for this card (AGP) over the last few days (sold ones - not unsold).

So, somewhere about there i suppose.

Care to PM me an offer and we can discuss or is that more than you were expecting? (It was more than i though they were going for TBH).

Re: Im going for it - Monster O/C on Pentium D 805
 

Bloomin' great link, TBR :tu:

Re: Im going for it - Monster O/C on Pentium D 805
 

Might have to do this myself :O

Re: Im going for it - Monster O/C on Pentium D 805
 

I'm seriously tempted to do it too... I can't believe the results they get from an £80 chip. I reckon they're gonna sell out PDQ once other peeps get wind of this.

I would need to get approval from my financial controller, but should be getting my yearly bonus soon, which would cover everything I'd need, so she might let me get away with it.

One thing I'd be worried about though is the amount of noise that Zalman hsf kicks out running at full pelt. Don't fancy going down the water cooled route, so would have to be air cooled which is gonna be noisy at that high a temp.

Anyway, from a huge AMD fan, this is damn good stuff! :)

Re: Im going for it - Monster O/C on Pentium D 805
 

One thing to watch here peeps - i've been investigating this in a little more detail and have actually cancelled my komplett order for the time being.

The bundle mentioned above comes with

TwinMOS DDR2 PC4300 1024MB Dual Pack KIT w/two matched DDR2 PC4300 512MB CL4

Now this is DDR 2 PC4300 memory but flicking through the toms hardware link we see the following table:-

Pentium D 805 with 20x Multiplier
FSB clock CPU clock
133 MHz (Default rate) 2.66 GHz
140 MHz 2.80 GHz
150 MHz 3.00 GHz
160 MHz 3.20 GHz
166 MHz 3.33 GHz
170 MHz 3.40 GHz
180 MHz 3.60 GHz
190 MHz 3.80 GHz
200 MHz 4.00 GHz
205 MHz 4.10 GHz
210 MHz (THG clock) 4.20 GHz
215 MHz (Maximum boot clock) 4.30 GHz

Which means that to reach 3.8 Ghz we need a FSB speed of 190Mhz - However the FSB speed also relates to the Memory speed also. Depending on how we can set the multiplier on the motherboard will depend on how far we can push the memory as well.

So the motherboards memort multiplier needs to be able to be changed DOWN from 4 (normal multiplier) otherwise my 4300 Memory is going to need a serious reconcideration.

190 * 4 = 7600 Memory.... (if i understand this correctly) :Yikes:

It needs to be 2 or 2.5 if we are going to keep it stable (3800 - 4750).

FSB (MHz) Multiplier Bandwidth
133 - 148 3.00 DDR2-400 up to 444
133 - 148 4.00 DDR2-533 up to 592
149 - 266 2.00 DDR2-298 up to 533
149 - 266 2.66 DDR2-396 up to 710
149 - 266 3.00 DDR2-447 up to 800
149 - 266 3.33 DDR2-496 up to 888
149 - 266 4.00 DDR2-596 up to 1066

I need to check the motherboards manuals in more details before i go ahead with this to see what support it has for the memory multipliers.

Edit: checked the manual - but it doesent go into much detail about the BIOS memory timings available.

Need to look elsewhere.

Re: Im going for it - Monster O/C on Pentium D 805
 

That cpu looks like its been designed with this in mind, a ridiculously low fsb and a high multiplier just cries out.At 4 gig you wont even be overclocking the ram

I too like Gareth am an ATI fanboy but this is certainly appealing

Noticed last post im not sure off how DDR2 works
The 6400 will run at 800mhz doesnt that hit the 4 gig?

Re: Im going for it - Monster O/C on Pentium D 805
 

Yeah, maybe forget buying a DIY kit and just buy the bits they detailed on p14 of your article... at least you know that it's been made to work with that hardware.

Re: Im going for it - Monster O/C on Pentium D 805
 

The good ram is bloody expensive and it appears to run at real high latency isnt that the trouble all along with ddr2

Re: Im going for it - Monster O/C on Pentium D 805
 

Very good choice, and any DDR2-800 Ram would work, go for the ones with lower latencies obviously ;)

---------- Post added at 00:56 ---------- Previous post was at 00:55 ----------

Pricing one of these up now
As long as i can flog this PC i shall be all set :)

Re: Im going for it - Monster O/C on Pentium D 805
 

Looking at another 100 quid for the same amount of memory (1Gig) over the Twinmos 4300 stuff to something like 5300 from OCZ.

You could get away, maybe, with something like the Corsair 2GB DDR2 Value Select PC5300 Dual Channel Kit.

But thats the week point now... still its 2 gig as oppsed to one at the same price as the OCZ.

But to play it safe and have the memory you need (2gb) - you really something like 6400 memory like the Corsair at 200 quid here..

Borrox..!

---------- Post added at 01:00 ---------- Previous post was at 00:57 ----------

Just priced it up with the 6400 Corsair memory - instead of 210 quid its 370 assuming the same bundle but without the memory and bought seperately obviosuly.

Meh! Bah Humbug!

Re: Im going for it - Monster O/C on Pentium D 805
 

well if the cpu can handle it then it will still be a monster machine for the cash.Of course just cuz Toms hardware can do it does not mean you will be able to,However if you can get the cpu say upto 3.2 gig then your still going to have a very powerful machine for the cash so its still gonna be a good project even if you go with lesser ram surely

Re: Im going for it - Monster O/C on Pentium D 805
 

Unfortunately not as i also have my season ticket to renew this month as well.

Perhaps next month.

Re: Im going for it - Monster O/C on Pentium D 805
 

In that case google overclocking the opteron 165. Give as good as fx-60 performance without the cost so they say. I'd love to try it but my 'financial controller' will not go for it.

Re: Im going for it - Monster O/C on Pentium D 805
 

And less cache

Re: Im going for it - Monster O/C on Pentium D 805
 

Yeah, but they're a bit more than £80 to buy though, aren't they? One of the things I like the most about this Pentium D 805 solution is the price... well, the price once you've OC'ed it a helluva lot ;)

Heh, never thought I'd say that buying intel would be a smart move financially :D

Re: Im going for it - Monster O/C on Pentium D 805
 

And might actually be the same when Conroe is out... Intel look to have actually thought about high performance gains... and of course look like they can compete with the top of the line AMD's comfortably.

I've just noticed my bank account is very low right now... I'm basically only able to afford around £200 of anyhting, and i want to keep most of it anyway.

4.1Ghz dual-core for 80 quid
 

And no, it's no joke http://tomshardware.co.uk/2006/05/10..._ghz_cores_uk/


Edit : TheBlueRaja did it first, damn the obscureness of his title.

Re: 4.1Ghz dual-core for 80 quid
 

Been posted already unfortunatly, i think the thread was entitled Intel Pentium D 805... Something.

Re: 4.1Ghz dual-core for 80 quid
 

Holy cr*p! :disturbd: :D

Re: 4.1Ghz dual-core for 80 quid
 

Hmm, can't find any on the Overclockers site. Want one though. :D

Re: 4.1Ghz dual-core for 80 quid
 

Damn you for not looking hard enough.... :p:

Discussed here:-

http://www.cableforum.co.uk/board/sh...ad.php?t=47233

And its going to cost you a lot more than 80 quid im afraid.

Don't buy from overclockers. They are a bunch of cowboys.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Bumping this thread cuz im just about to build one :)

---------- Post added at 19:36 ---------- Previous post was at 18:02 ----------

installed in case first boot fine installing windows :)

Am I boring posting these lol lol ????

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Build complete no hic ups not over clocked yet may leave it till morning

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

nice one :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

My first LGA 775 too dont like the heat sink assembly at all simple to install but wont be simple to get off again.no pins to bend now you gotta like that lol

All ready for the conroe next month ;)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Overclocked and stable on stock cooler to 3 gig no problems.Its a little warm under load so I cant push it any further without out other cooling which I will be doing soon :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Sounds good.
Any more tech details? Mobo, memory?
How much did it set you back in the end for Proc, mobo & mem?

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

And I thought my P4 ran hot any way (65C underload). Good luck with the overclocking!

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Gigabyte mobo 1 gig of 667 ddr2 and the cpu about £200 notes im running with a 200 gig sata II hdd and basic gfx for now as its not my main machine :)

Under load at 3 gig it runs prime95 at 57 degrees

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Excellent stuff, but crank it up - you know you want to!

When the metal can on top of the chip goes ping you've gone too far.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Hmm, wee need the goodies mate, 3ghz is not close to what was promised really.

How is your Mobo for multiplyiers, are you able to adjust CPU speed independant of memory speed?

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

yeah theres a multiplier for the ram as well as the cpu.Im gonna order me a hsf for it and see im gonna try for 3.4 once I get it.Should make 3.6 will just notching up the vcore.The stock hsf is bilge and seeing as ive never built a PGA 775 until now I dunno how easy its gonan come off lol.
All thats stopping me is the stock fan
Any idea what the upper threshold is on these chips save me looking myself lol lol

---------- Post added at 13:51 ---------- Previous post was at 13:13 ----------

Ok 3.2 gig case side off and its 54-56 degrees running prime95 stock cooling
This is a nuts cpu

---------- Post added at 14:19 ---------- Previous post was at 13:51 ----------

Ok underclocked the ram to 3.33 x multiplier and upped the fsb to 170
posted a booted at 3.4 gig test time

---------- Post added at 14:30 ---------- Previous post was at 14:19 ----------

so far no difference in temps this is nuts

---------- Post added at 14:31 ---------- Previous post was at 14:30 ----------

screenie Bare in mind this is stock cooling and no increase in vcore

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Looking sweeeeet mate - keep it up - should go much further.

Dont suppose you could do a Sisoft Sandra benchie for comparision to other systems?

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

you provide the download lol Im not pushing it any further with stock cooling but its nuts though isnt it.Wish id bought a better hsf im enjoying this.Gonna let prime95 run all after noon then run 3dmark 2001 or 2003 for a couple of hours.
My main prob is the gfx is passive cooled might strap an 80 mm on it lol

My advice is if you got 200 quid to spend play with one of these babies

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

I am now thinking about getting one of these babies. My Athlon XP 2100 is getting a bit long in the tooth for me.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

go for it its a real bargain and you dont get many of those in life lol

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

I wish I had the money :(

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Well I have a brand new xbox360 I need to shift but once I do thats what I'll be spending the cash on :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

They will be around for a good while :) and most likely get cheaper.Intel have done a mad thing with this cpu 20 x multiplier woohoo lol lol

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Woot! BTW Thanx for keeping us up-to-date on it matey... :tu:

I'm tempted to take the advice of a certain NTHW clanner (who shall remain nameless for legal reasons) and swap my HD out, drop my computer down the stairs and then claim on the insurance. Knowing my luck i'll end up doing porridge for it.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Lol good luck mate :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Linky

Here you go chief...

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

ok ill bench it tonight .What you want me to run lol I want to leave prime running till about 6 then I know its stable lol

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Every benchie in Sisoft would be a good start Zingle ;)

Then maybe a quick run of SuperPi 1m ?

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

I know I dont have much of a life but Geez lol lol

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

It's worth a greenie, and SuperPi 1m takes literally about 50seconds... I'm guessing 47 in your case :)

Also, the sandra benchies are incredibly quick too :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

save me time link me

Processor arithmetic couple of interesting results :)

Ok run a few tests basicaly its better then an x2 4000 better than all the single core cpus including the E 3.8 gig cpu,It also holds its own up to the single core amd 64 cpus.
Its battered by the fx60 and high end dual core intels But for £80 a dual core cpu that competes well upto a £220 cpu is very good value indeed

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

http://www.short-media.com/download.php?d=457

Liking the results beating a 4000+ Thats one option down for me... Shame looking at the Hyperthreaded Extreme Edition really, but it still holds well!

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

which you want me to do the 32 M?

Oic 1 m lol

---------- Post added at 19:48 ---------- Previous post was at 19:46 ----------

39 seconds

same test again this is interesting and the Pi score

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Holy ****. My Celeron D @ 3.46 does 512k in 29seconds :O

Thats one fast CPU.

Next round of benchies please ;) Memory bandwidth etc :p

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Its wees on the fx57 for gods sake
and it beats the D 840 :)

The memory wasnt part of the project as I intend to sell this pc theres only 1 stick = a gig which is going to be carried over to my Conroe machine in august

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Christ, good bye FX-57 :O

Looking more and more likely i'll be getting this over the P4D 930 ...

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

well I have to say it again this is with stock cooler no vcore rise this will go a lot higher I think me ording a artic freezer7 pro :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

I may just go water cooled in the end... Will be my first watercooled rig ever though :o

---------- Post added at 20:59 ---------- Previous post was at 20:03 ----------

Just run bennchies on mine... It is almost exactly twice as powerful. Mine tops in at 7510 MIPS, and 6157 MFLOPS. I can beat an FX-53 :p

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

God damn - i think this is a must now, this looks like a beast of a CPU.

I know nothing about the test its 1million places run the test and screenie it need proof.Like I say i know nothing about the test.Run the sis and show us you beating my cpu there too :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

my 3800 takes 40

fair play now show me a screenie of the sis test then tell me how much it cost

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Sis test? as in Sysoft? I'll need to download it, here's screenshots from CPUZ, processor cost me £82 inc vat from Savastore, only overclocked by 600mhz (far less than your 805 D).

However, yours appears to kill mine on the CPU arithmetic test.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

see that prob won on ram.Lets see the processor arithmetic test off sis ? I bet you beat my cpu with shear ram lets see if it beats it in the other test

i wanna see the screenie of the sis test ..you would wee on my mem bandwidth too :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

As mentioned, CPU arithmetic is very poor, memory bandwidth is pretty good though, not bad for inexpensive ram (£140 for 2 gig, new)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

I only got 1 stick of ram and latency on ddr2 is crap to say the least im only running this project to test the cpu.You were ready to post your screenies that beat my cpu its only fair we see a sis screenie to balance the equation

Just as a little add on to this it also runs vista with full driver support :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

looking at that zing, you need some more air flowing to your GPU and quick......

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

why? its only 52 degrees ???? Its passive cooled I know its crap but its not a gaming machine.Im waiting till friday to buy my freezer 7 cuz aria are having a rush hour day different products on offer for an hour so hopefully something will crop up,Ive though about bodging a 80 mm fan to the gfx should be doable but its not going to be a gfx machine,If i keep it its main job will be video encoding (good ole netburst)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

while it may seem ok to you, and it is for a short time IMO, for the sake of a larger low rate fan mounted to the front inner case your going to get a far better airflow to the back and also help the cpu fan do its thing too. :)

personally, id rather try and source the largest copper heatsinks with lots of long fins, and fit these to a main encoder machine (you got an ati X1600 or better for the GPU encoding ?) cpu/northbridge/gpu/etc rather than rely on fast and noisy fans, but it seems really hard to find large cost effective copper heatsinks in your local computer shop, arr well :)

any req on current silent (or near as possible) PSU's that are cheap and plentiful, to spec too is always a good thing, my current one is on its way out and the 5 V is wondering below 4.5 v at times Arrrrrrr.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

dude you talking to me like im a noob.I have a lian li case with proper cooling from the off.I didnt say I was doing graphics I said video ie changing one thing to another nothing to do with the gpu.52 degrees isnt to hot for a gpu

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Ran SuperPi on my P4 just for comparison - 1M took 40 seconds, so that is really a fast CPU for the price :erm:

And for the record, I've got a P4 3.2GHZ Extreme Edition (Gallatin core, or also called the "Northwood Extreme Edition").

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

cool :) im really happy with it.Im ording the artci cooling frezer 7 pro tomorrow and im gonna hit it to 3.8 with 1 up the vcore I think ive fell on a good chip here i reckon its gonna be stable at 3.8

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Do you reckon 4.1 would kill it then?

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Was that on air? I dont think it was was it?

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Water.

I tghink 3.8 will just about be its absolute max on air, they're saying the top Zalman fan can take it upto about that, so the arctic may manage it.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

I may well have a go at 3.8 :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

ok its just posted and loaded windows at 3.79 gig (god knows how the maths there works lol ) testing to follow gotta fall over now its stock vcore still and still stock cooling

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Hope you have a nice cool beer with you. I was reading that original article - a typical PC munches 500W at 4.1GHz :Yikes: . You're not so far away now.

That's not far off being a fan heater.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

The stock fan is keeping the temp constant it wont be heat that stops this until the vcore has to go up.None of the reviews ive seen have had one at 3.8 gig on air let alone stock cooling for so long.Its still running prime and has been running an hour,Ill screenie when prime has done an hour then ill do the sis test again.If its still alive lol :)

Looking good, i'm leaning more towards the D805 now over the 930... But i'm still unsure, the thing that decides it for me will be how high it can post on the Arctic cooling... If it hits 4Ghz on air i will most likely drop the 930 from my list of possibilities.

Can we get a SuperPi time at 3.79Ghz?

I cant see how its still running .Nearly 3 hours running cpu intesive apps the whole time and no crash I didnt expect it to be stable.It still might not be but its been busy

Well, you'll be surprised at what can happen, i mean, aren't these things fine until they hit something like 70'C? Or was it 65? Either way their lots of headroom usually. This CPU is proving it's worth though, i'm going to start piecing together my next PC ready for my paycheck. Could you post what motherboard you're using? If it has support for SATA-II? etc... (I'll look it up if need be, just post the model)

Thanks, and.. erm... SuperPi ;) :p

36 seconds super pi but I think ram plays a major role in this test


I am running a sata II hdd I think I posted all the specs but its this Gigabyte board

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Zing, it won't crash due to the throttling technology on the chip. As soon as the CPU reaches it's high temperature, it'll start to slow the CPU down.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Then how will I know when that happens? According to custom pc there machine crashed at 3.8 gig after 5 minutes.
It wont be temperature that crashed this cpu it will be frequency.Its already proved it is stable under 60 degrees at all the clocks the temp has not changed.The cpu will crash when the frequency is to high for the cpu to handle at that voltage.Then I can raise the voltage and this should allow for higher frequencys however this is when heat plays a role because the overall wattage wastage increases and of cause then you get heat.

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Tom's Hardware Guide were using some sort of software to detect when the CPU started to throttle, but I have no idea what the software is called - I don't even think they told the name of the program :(

I think it was around 3.4-3.6GHZ that it started to throttle, but I'd have to check the review again.

If Custom PC's machine crashed after 5 minutes at 3.8GHZ then it's possible that the throttle technology didn't do a good job on their machine.

well thats not happening here cuz the benchmarks keep improving

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

Must be better room temperature then :p:

It's called throttlewatch. Enjoy ;)

And Zingy, that mobo looks sweet, i shall be getting one :)

Re: [Merged] 4.1 Ghz Dual Core Pentium 805 Monster
 

ok maybe this looks like its happened its capped itself to 3.7 gig :) bios read it as 3.7 even though the system reported it at 3.8 so maybe some kind of cap.Ill bung the new HSF on monday and raise the vcore a notch and see if it reports properly :) So its hit its wall at 3.7 gig guys with stock cooling and stock voltages :)
