I decided voltmod it.

VGPU mod (back side of card):

27 kOm, from 2.72v up to 2.8v, memory hynix 2.8 ns

So, now i have 551/950 Mhz and 6875 3D MDarks on this system

Thanks for the info, and welcome to XtremeSystems.

How did you come about your mods?? Did you have the data sheets for the 2 regulators, or did you figure it out yourself?

WOW that is very impressive for hynix memory which tops at 820 unmodded. but the core, keep tweaking and you too like me could see 600, i got it on air (non POV card too)
with an a64, you will see 7500.

I found only one datasheet, and it was very long story... :-).

Without Vcore mod I had 440 Mgz on my card.... So, Vcore mod helped me to get more 111 Mgz... :-).

Viru$ - it is strange that you only managed 440MHz on air... My Palit/Xpert Vision goes up to 485 artefact free with stock cooling...


Anyway I'm interested in vmodding the GPU - can you send me a link to get the data sheet? 10x in advance

i think your score is very low..
i have got a gigibyte fx5900xt 490/800 andt its skore is 6755... i understand that mod it isn't very useful...
