super pi database
 

Anyone know of a place to look for cpu's running super pi at stock ?

I got 29s 1M for an E6400@stock seems a little off to me

Overall must say the machine has benched 'OK' nothing great as expected.

Windows run better but still have that little clunk clink lag you get when you open windows dont get that with linux.

Hopefully after benching a bit more with windows I'll get back to the real world and linux.... It just disrespectful to all this wonderful hardware to be spoiling it by running windows

Re: super pi database
 

what ram you using? remember ddrII has very poor latency

Re: super pi database
 

ddr : latency is good I tested with sis sandra but bandwidth is poor as expected

Here are some comparable super pi results but they are from machine that are o/c'd

Re: super pi database
 

of course it is your on the asrock how quickly I forget ;) I score 21 secs at stock

Re: super pi database
 

Looks like an E6400@stock is around 28-29s

What process and speed are you on mate ?

Re: super pi database
 

just back at stock I want to sell this board and chip in the new and buy a quadro ;)(no one else will buy me one sobsob lol process?

Re: super pi database
 

what processor and what speed is it running at ?

Re: super pi database
 

am jealous of you 2... I just tried the superpi and ended up with 42s on 1m. :(

Re: super pi database
 

lol ok E6600 at stock it was scoring 17 at 3 gig but ive clocked it down cuz I wanna sell it and not strain it

Re: super pi database
 

LOL nothing to be jealous of : I have yet to tune the system :D
I just ran super-pi on my laptop 900mhz pentium-m and got 1min 50sec which is not bad at all.

Re: super pi database
 

yeah but how old is that lappy.....and its a lappy ;)

mine is a full sized desktop (okay 3 years old now) so yeah I think i can still be proud of only 42 secs :D

Re: super pi database
 

Yeh its a lappy running linux and it too has had it's 3rd birthday

Historically pentium-m's are kinda special : I was gobsmacked by it's performance running seti when I got it.

The intel core 2 duo has roots set from this processor

Pentium-m > core duo > core 2 duo


still think that 21s vs 29s is way too big a gap time to trash windows :)

Re: super pi database
 

Here's my scores.
Super PI

Stock 6600 = 20sec

@ 2800 (small o\c) 18sec (CPU @ 1.35v - Mem @ 1.8v)

@ 2880 = 17sec

Re: super pi database
 

grrrrrr must be a big difference that cache is making to super pi results....

As I have seen others running E6400@stock getting around thge same as me.

I knew I shouldn't have scimped n saved pah : Then again I do now have a good system

Just installed linux and the super pi result was just as per windows

Re: super pi database
 

19.7secs @ 3Ghz.

Something tells me that's the cache hit, or the high latency of my CAS5 Ram.

E6300 btw.

Re: super pi database
 

17 secs on a e6700 2gig of OCZ 900mhz mem. Stock speeds

Re: super pi database
 

I would say a cache hit as the mem i got is crap compared to what most others run.

Admin has just mentioned to me that I need to apply for more funding to get some quality mem to get a bit more out of this beast.

Thing is im also having to save for something else (that dont need overclocking) so funds are very limited at the mo.

Re: super pi database
 

It will be as the memory bandwidth is nowhere near that of the equivalent (sorry, nearest) AMD processor. That should rule it out to begin with.

Re: super pi database
 

Thanks all to those who contributed this thread.

Think I'll be binning this mobo at the earlier available opportunity :)

the E6400 is supposed to be a good clocker

Re: super pi database
 

She'll hit 3Ghz easily ;)

Re: super pi database
 

Yup easily but not on this board she wont :)

Just upped the FSB and got 27.5s I'll try the limit which is a lousy 295Mhz

Should I voltage mod my new equipment already ? tempting but I aint got a cooler

Re: super pi database
 

No volt mods should be needed.

Re: super pi database
 

LOL This IS the Asrock we're talking about there's no vcore modification within the BIOS unless of course the latest BIOS has it

Re: super pi database
 

34s on an AMD FX-55 ClawHammer @ stock speeds (which is 2.6GHZ). Won't try overclocking until I get a new motherboard.

Re: super pi database
 

Since u're a linux boy how are u running super pi ? Old Commandline version or under wine ?

Re: super pi database
 

Actually this is on Windows for gaming.

Re: super pi database
 

Traitor : Reps added : LOL

Just kidding dont blame u btw

Re: super pi database
 

Proper memory controllers ftw! Not bad at all =)

Re: super pi database
 

Dude, why didnt you take your own advice?

Re: super pi database
 

The price. His financial controller seems to hate him buying things =P

Re: super pi database
 

My new work laptop does 35s - a 1.8Ghz Core Duo (not C2D) :)

Re: super pi database
 

Almost the same thing - C2D is heavily worked Core Duo : Nice chip

LOL the cash besides as Druchii says missus is a factor but then again she has no control of my finances - as long as the bills are being paid she dont give a toss. :) Being unemployed for a year also plays a factor - It always happens to me when I'm on my tod I end up spending on hardware.... When I'm working I just dont get the time to play ! Funny world.

Anyway having looked around seems like 26s is the time for a stocked E6400 I'm lagging due to the cr*p board but

Nonetheless getting one of those sexy new boards the E6400 due to it's multiplier will OC very well on air.

Re: super pi database
 

I always say buy the products where the balance is price/perfromance the c2d balance point is the E6600 also its the first proper Conroe and the lesser chips are different and always spend as much as you physically can afford

Re: super pi database
 

Hmmmm

E6400 £144 mobo £36 ram re-use old DDR 1gig = £170

E6600 £210 mobo £50ish lets just get a cheap 1 £100 for 1gig of DDR2 = £360

Thats a hella lot of difference.

Re: super pi database
 

whats stopping you putting the E6600 in the cheap board? its also a true conroe which the lower chips are not. so the difference is 66 quid

Re: super pi database
 

LOL Good point ZIng !

But I thought I'd use the money to buy a pair of SATA drives and so the overall system performance is enhanced

Re: super pi database
 

Ther are some people on another computer forum that do Super-Pi @ stock and O/C

http://www.buildyourown.org.uk/forum...TOPIC_ID=18050

Re: super pi database
 

I dont know what my chip does at stock speeds because quite frankly its never run at stock for more than a few minutes when i update the bios!

However at 3.7GHz my e6700 crunchs 1m super pi in 13 seconds.

The conroe does so well because of its shared 4meg caches, the allendales with there 2meg cache do suffer.

However they fare much better than athlon's which at best have only ever had 1meg of cache avaliable per core (the c2d has a unified cache both cores see the same cache) and currently most that are on sale only have 1/2meg of cache!

Re: super pi database
 

Nice thread again confirming that I should be in the 26s arena... I will be tuning once I have the time.

Anyway at least I beat this guy :D

47. bfbf - Pentium MMX 166MHz @ Stock - Stock Fan - 2211.014s

Spot on Keith.

Zing really there is no architectural difference between the Allendale and Conroe albeit the cache and hence in this test the E6400 suffers... All my other benches put the E6400 10% down on the conroe except for the ones where cache is heavily used.

Oh well I'm still happy beats playing with an Athlon :)
I even missed the whole Athlon64 upgrade thing as I saw it as only marginal performance gain over an overclocked XP-M but the gap widens with the C2D platform to ~100+% gain hence my upgrade :D

Re: super pi database
 

Current Allendales are infact failed conroe's with 2megs of the cache failed. Unfortunutly you cant unlock the cache!

This does give the die a higher surface area / power output than the conroe's which is why they tend to overclock abit further.

There will be true 2 meg allendales coming soon which will be cheaper chips and probably end up being the new celerons.

When the core 2 originally came out and they had engineering samples of chips, several sites did comparisons between 2 and 4 meg chips to find where the cache mattered, and superpi was one of those cases.

Edit - Here is one of those reviews for where cache matters, http://www.anandtech.com/cpuchipsets...spx?i=2795&p=4

Re: super pi database
 

thought i would resurrect this old thread rather than start a new one.

current i3 @ 4.4GHz superpi 1M @ 10 seconds

any other latest times with new kit?
