there was one, but i know that for me it only caused artifacts....Originally Posted by MonsterMash
whether it actually works or not, i dunno, but i didn't leave mine on.

Asus ROG RIVE X79
Intel Core i7 4930K, @ 4500MHz

3x AMD HD7970 GHz Editions

Vmem mod is not really worth it. 3850's gain much more from GPU Mhz than Mem Mhz. That's why 3850's clocked at 775/2000 perform almost identically to 3870's clocked at 775/2400. Going from 900 to 1050 on my memory gives me just 1-2% fps increase.
My 8800GTS G92 works the other way. GPU increases make little difference because the memory bandwidth is the bottleneck.

Can anyone confirm this?
Is this only for 3870 or will this work on a 3850?
If the pencil mod doesn't work, I will be hard modding and have 2 questions
1 Are both pots, core and mem, 100k ohm or is the mem one different?
2 Do I need to flash Bios with whatever voltage I'm trying to run, or just leave where they are now?

1- you use a 500k for the mem and a 100k for the core.
2- you can use the stock bios, but you will hit a wall at 864 core. you need the pll fix bios.

OK, thanks, I missed that in the thread,
I'm running HIS IceQ3 Turbo bios, CCC goes up to 900mhz with that. Will I still need the fix?
