7900 GTs @ 1.7v/2.17v... does it get any better?

[CompGeek]

I just want to see what someone else can do with dual 7900 GTs on Conroe, because, from what I have seen, these are the highest clocks benched on 7900 GTs (Referencing both ORB and HWBOT). And I don't consider myself among the elite. I also have a question, can the oscillating resisitor be lowered to ~30Kohm? Because the recommended is 45Kohm, but I need the 38Kohm im using right now for decent stability @ 1.7v. I'd like to go lower, I think i would break 13k. I dont, however, want dead cards.

with my friends setup i benched 750/850 on zalman vf900 1.7v.

what was your cooling?

oh btw i find the benchmarks are faster with the ram under 900 even though it would run about 985 or so have you checked if it can be faster at 800-850 ram speeds?

Very nice compgeek, I'm still undecided on whether to go 7900gt or x1900xt, I'm leaning towards the GT, maybe we can do some single card competitions :) my conroe should be here soon enough

the 1.7v is where you remove a resistor right?

Hey compgeek,

I added the core and memory overclock in the collapsed result view (http://www.hwbot.org/ResultBrowseByVideoCard.do?gpuModelId=742), so it's easier for you to search.

Seems like you've got the highest core overclock. I can find a few with higher memory clocks though:

i can bench @776 with 1.55v, but too scare to void the warranty for 1.7v

[CompGeek]

It was on water, memory is bare, i am going to try benching with lower clocks as well. Know how this stuff works :)

1.7 is where you replace the 5Kohm resisitor with a 50Kohm, yes.

Hmmm, I dont see any SLI with higher memory ;). Ill take it higher, i thought this would be my ceiling but i think i can do at least 1010.

Very impressive score. Run some other 3dmarks now :)

05 seems to be pushing CPU limitation. My score is 21311

Really? My score was higher with my opty 146 @ 2.9 and my 7900GT @ 600/950...

edit : *cough* err maybe that was 03.

*cough*

[CompGeek]

So... you have scored 22k in 05 with an Opteron 146 and single 7900? Let's see that ORB... :rolleyes:

LOL :D

I edited the post before you made your post, I forgot it was 03.

Not to mention I can't afford ORB ;D

[Demo]

whats some huge volts and nice core clocks.. 800 , thats 350mhz more from stock!

I know, I was laughing at the cover up :rolleyes:
