HD3200 @ 1ghz! Validated, but need help getting stable

post #1 of 3

4Gtexels / sec + 4Gpixels / sec (not rounded up, everest reports 4005 or so). Plays starcraft 2 at 1280x720p with (dual core @ 14*250, 3.5ghz / 4GB DDR2-1000) with low quality 60+ fps, or medium at 25+ fps. The rest of the specs are in my profile HTPC rig (not sig). I can't find much info on this chip anymore, wonder how close that is to the record OC?

Problem is, during Starcraft 2 I started getting video artifacts after about 5 minutes.

NB voltage is as high as it goes (1.4V), cpu-NB is 1.3 V (bit more room there) as well and is clocked at 2500 (250 FSB * 10). Temperatures reported by TMPIN2 are 38-42C so its not hot... HTT link is also at 2500.

Anything I can do to help the artifacts (+rep for anything that works)?

Can overclocking your NB this hard affect your Sata drives (corruption)? Since they are technically tied off the SB and communicate through the NB to the CPU

thanks,

The onboard 3200 is run by the 780G northbridge. Given this, raising NB voltage will help stabilize higher overclocks on the IGP. Since you are at the limit, there is nothing else you can do. Perhaps a volt mod or something is possible, but I would not recommend doing this. CPU-NB voltage is irrelevant and is directed towards part of the processor- it can help with faster frequency RAM or a higher NB frequency, but will not help in this case. The only thing you can do is back down on the frequency until it is stable.

There is no risk of hurting anything with what you are doing. One thing I would like to point out is HT Link should be left at 2000mhz, or as close to 2000mhz as possible. Raising it higher does nothing and in fact may even worsen performance if I remember. The NB frequency is what you want to raise higher while keeping the HT link at around 2000mhz. So you can leave the NB multi at 10, but go ahead and drop your HT Link multi down to x8.

Thanks, thats a good suggestion, if my mobo will let me change the HT this time, being Am2+ it is a little finicky with the HT/NB multis (it warns if NB<HT, then it will auto adjust, but last time I tried changing both multis from 10x to say 9x, it reset them).

Failing that, I guess i have to settle at the stable 900, shame as it scales really well with clock speed.
