8800GT bios for better overclocking! *test*

[mrkarate]

hi, I have a XFX 8800gt XT, default clocks are 640, 1650, 950, and I do the volt mod flashing the bios, nvitor say that is ok the flash, 1,1v on the extra voltage, and my clocks range now go up to 770 and still working, maybe can do more, I continue testing, shadders go up to 1750 from 1700, but mems clocks it´s the problem..., without vmod, maximun stable to all games, was only 960, and after vmod, still the same frecuency, 960, if i go to 965, after play 20 mins or 30 on crisys, or after play 5 mins on pro evolution soccer (other games don´t give me a crash), I have a green colored pixeler screen for 10 seconds, and then the pc is freeze, or give me a blue screen with a nv4_dsp.dll error, is vga mems the problem? or was my pc specs?, I have a opteron 165 @ 2750, and a nforce4 based motherboard (msi k8n-sli) 2x 1 gb ram ocz platinum ddr 400 @ 450.

I have the stock Cooler, with 100% fan, and have 88º maximun on crysis only

Thanks!
