I am going to do this mod again on my set of 8800gt now and I guess if they can be pushed to 1.625, then it seems there isn't any point to go all the way down to 1.2k. Seems like 3.8-4.2 will do that trick. I am looking for 1.55max, so you think 4.2k will do or will I need the 3.8(ie is 1.625 with 3.8 or 4.2?)
I don't know the equation, but VJ told me 3.8-4.2k would give you 25% headroom. I know ~1.3v idle is where OCP kicks in, so 1.3 x 125% = 1.625v.

Largon said 1.2k gives you 50% headroom, so 1.3 x 150% = 1.95v.

I used 3.92k, but haven't gone any where near 1.625v yet, so I can't tell you for sure. I think you'll be fine for 1.55v w/ 3.92k or 3.8k if you want to be sure.

Someone correct me if my interpretation is flawed.

Any help would be great.



Edit - looking at some of the clocks in this thread the GT clocks much better than my GTS , is there a brand/model of GT to look for ? One with better overclockability ? Better ram maybe ?

Cheers .
It varies from card to card. My GT did a little better on the core, but the GTS did a lot better on the shaders. The GTS has 3 phase power, so my gut tells me it would handle the increased voltage better. Also, the GTS does much better on memory clocks. At the same vGPU, and w/ tweaked memory my GTS scores 1200 points higher in 3DMark06 than my GT. Plus you don't really have to do the OCP mod on the GTS (unless your going extreme cooling).

Ideally you want a GTS w/ Samsung memory. I have no idea how you'd be able to identify one, though. Perhaps a more recent date on the box would give you a better chance at getting the Samsung chips?
