Anyone have artifacts while running fsb and memory 1:1 at 250fsb 3-4-4-8 on the IS7 motherboard? Please help. I can run 235fsb/235 memory the highest with no artifacts. This cpu is stable at 3.25ghz tested already.

Could be your north bridge overheating. Do you have decent airflow?

And i assume no overclocking on the GPU right now either?

I agree...Plus also as you raise the fsb of the chipset you need to rauise the vagp...The vagp which at default is 1.5v is what supplies the northbridge chipset. look at cooling and look at raising it to 1.6v...

Also what makes you think it isn't related to the ocing of your card??? lower it back to default and if it doesn't artifact then it is likely the card and/or the fact the vagp needs more juice....

Do you not see my sig? I am not ocing my card at all. My northbridge has a huge heatsink with fan like on the new IC7 max3!!! I tried 1.6 volts it does not work.

Hmm, why not back the memory down bit? Or relax the timings. Run a 260-275 FSB on the 5:4, that will keep your memory WELL within spec.

OK...Next time lose the attitude cause hours ago when I replied you listed the vid card as 440/900 and no voltage so you obviously changed it...I have a good memory. I knew that wasn't stock so I thik you owe me an apology!!!!

On the main note I had heard of some talking about a 255fsb wall and that a newer maybe 1.7 bios helped that....

Well on Gainward Ultras 440/900 is stock :) I changed it so I would not hear anything about that. I did finally fix the problem though. I had to rerun detonator cleaner to get all the old .dlls and such. Reinstalled the driver and all is good. Running 250/250 1:1. I still dont get the awesome benchmarks everyone else gets. I did not mean to have a attitude at all. I was just fustrated at the time. Thanks for the tips though.

I have the same problem with artifacts on and FSB 250/1:1 when testing 3DMark03 CPU tests and AquaMark.

I have tried all the suggestions here with no results. I back the FSB down to 200 and came back up testing at 5 mhz intervals. The artifacts start to come back at 230 FSB.

I recently switched from Corsair PC3700 Twinmos-1024 to OCZ Gold PC4000 1GB. I couldn't get the FSB to run stable at 250 1:1 with the Corsair but ran Prime 95 for several hours with no errors.

I never the saw the artifacts with the Corsair memory at 233 FSB 1:1.

Why now? Have I crapped out my CPU? Video Card?
