amd duron 900 overclocking

I take it being on an asrock board that its newer than the cpu mulitplier will be locked on the cpu so your totally dependant on fsb.also i would imagine its a 100 fsb or 133?? on a clock mulitiplier of 9 or 6? Did you have to underclock the board?? What ram are you using as this could have an effect.

If it is on a newer board and your using ddr the only restraints I can see will be either temp of cpu or cpu threshold reached. Up the fsb in 5's at first if instability is reached before to high a temp find vcore and up this a point or 2

I may be off track on the asrock but I cant remember them past a couple of years ago

the mobo is a asrock k7vm2

So its a ddr board what ram are you using??

2100 ddr

Just googled the chip runs on an fsb of 100 mhz, Im guess at the least your pc has pc2100 running at 266 so this gives you a threshold of 33 mhz fsb before you clock you ram. This times multiplier of 9 is a max overclock of 297 mhz before the ram clocks.I doubt you will get anywhere near this so have fun trying

if you have a bigger heatsink and fan bung it on ,remember when it first crashes up the vcore a touch if temp is still ok (make sure it is only a touch )

got the setup screen and got the cpu host frequency and the sdram frequency up what next the sdram is set at 100 but gives a 133 option the cpu is set as auto but gives a manual option

The ram is 133 but leave it as it is(reason for this is each up in the fsb will result in raising of fsb of the ram overclocking the ram can be avoided by starting it at 100 mhz).

Change the cpu to manual and up the fsb 5 ,reboot. If it runs up another 5 at this point stress test,I would use cpuz or prime95 for 15 mins should be enough,then if all is well and not to hot up it in steps .

If the machine refuses to boot just jumper the cmos and start again. this time up the vcore 1 step see how far it goes,I would have thought you would make 1gig but you never know how high it will go. Watch the temp very important this

the cpu is set at 100 so do i go for 105 or just go for it
only joking reebooting now

Ill be shocked if it crashes here

105 gives it 945 what do you think

upto you remember each increase is multiplied by 9 what temp is that giving??


you need another 6 to reach the gig (well 999 )

At this point I have to disclaimer myself just in case

go for it then but stress test if you goto 10 then measure temps.

what temp max on idle do you think

I would be more concerned that it jumps to high underload. Do you have a bigger heatsink /fan to throw at it add extra cooling??? If it gets hotter than say 60 under load its to hot.I remember the older athlons and durons running quite hot and being safe
