Well, I know nothing about soldering, so if I can't adjust the Vcore throught the bios, I just won't do it. Also, I am a bit of a newb and I'm wondering what "speed binning" is?

Sorry guys, my traffic was over the limit. Now the pics should work. Still some headroom with GPU clocks.

Opteron 170 @ 3200
7900 GTX SLI @ 750/940
82.40 Forceware (beta)
Win XP SP2

No voltage mods, no tweaks, everything is watercooled.

Point of View 7900GT Overclock...
No voltmods at all ;)
Thanks to www.mips-computer.de

well, after the volt mod on the gpu my 1 of my evga 7900gt oc sc does 610 3dmark06 stable. the 2nd card hated the vm on the gpu, in fact, i removed it and it has issues now. funny thing is that either card will just shut down at 1.35v on the gpu and really won't complete a run at anything higher than about 1.26v. what gives here? same thing with the memory, its much better without the volt mod on memoery. has anyone overclocked a gt past around 600, and if so what voltages. i am rather puzzled at this point as these cards really don't seem to respond to voltage at all.

i should note that this is the hardware voltage mod i am tring

whats the max the memory can do on your card mascaras?

i didnt see yet , but for what i saw in the forum depends in how much OC you have in the core like:

if you have only like 520MHZ in core you can do 1800Mhz in memory but if you have 560/570mhz in the core you only get 1700mhz in memorys , this its what i think for what im reading in the forum , not sure cause i didnt try yet past the 1650Mhz in memory . Max OC in core its 570MHZ ( stokcooler)

if the early results are any indication, the gt appear to have no headroom at all on the gpus

It's just cuz they are starved for voltage, we will get this fixed soon :)

same kind of tradeoff as on 6800's and 7800's.. higher GPU ->more heat, and less stable power. Shoot for highest GPU clocks, since give more 3DMarks (1700 is plenty).

cronic, perhaps overcurrent protection. Or, cold solder. What type of solder did you use, and did you make sure to clean the surfaces with acid/flux?

EDIT: yeah, starved for voltage and need better cooling (dont forget voltage regulators!)

My core craps out at 572

I think it wants more voltage.

I could try to use powerstrip to see if I can get the core higher.

how high should the gpu voltage generally be able to go on the 7900gt? with water cooling maze 4

those of you running watercooling on your 7900gt, what are you load and idle temps?

No headroom?... 450mhz is stock, so 110+ mhz on the core on stock cooling and stock volts is no headroom????
