atitool and furmark
Has anyone that thas tried this out noticed a higher vrm temp? Im wondering how much that I should give my chip (if any). I would like to break a 750mhz core. I can run 725 now stable.
I hope they get this working for the GTX 285.
I was trying to decide between tri-SLI 285s or quad-SLI 295s and ended up going for the 285 (one for now, two more later on).
But this tool looks like it could push the 2 295s to the top over the three 285s unless the 285s can use this tool. For the lower price, the 295 quad-SLI becomes much more attractive with this tool.
RIG 1 (in progress):

Corsair HX1000 / EVGA GTX 295 SLI / X-FI Titanium FATAL1TY Pro / Samsung SyncMaster 245b 24" / MM H2GO
2x X25-M 80GB (RAID0) + Caviar 500 GB / Windows 7 Ultimate x64 RC1 Build 7100
RIG 2:
E4500 @ 3.0 / Asus P5Q / 4x1 GB DDR2-667
CoolerMaster Extreme Power / BFG 9800 GT OC / LG 22"
Antec Ninehundred / Onboard Sound / TRUE / Vista 32
Just curious, what was your stable OC at stock 1.2V?
No amount of OC is going to give the GTX 295 Quad SLI setup 1GB of framebuffer - that is always going to limit it at high resolutions.
GTX 285 Tri-SLI is going to be much better overall than GTX 295 Quad SLI for 2560x1600 gamers. Certainly with AA enabled.

working great for both my cards, haven't tried in SLI though. using this method to under-volt the crunchers and it has worked beautifully.
Doh, missed the post.
But now I'm running into a very strange issue. I successfully can change the 2d voltages for both cards. But no matter what I do, I can't change the 3d voltages. I have tried writing to all 4 Ic2 bus numbers and still nothing.
EDIT: Nvr mind, figured it out

won't be the IC2 bus numbers, the registers are for idle and load. 15,16,17,18, one will be idle, one will be load. for each card in the one rig with two cards crunching, they each had different registers for idle and load. perhaps thats what you meant but hope that helps.
there should be 2 different I2C bus addresses for each cards VR if I'm not wrong. Unwinder is the man to talk to about this he could do it with his eyes closed standing on one hand while drinking a beer

nope, I2C BUS can be the same, you just have to specify the different devices. for instance, this is the line in my under volt config for two GTX 260s not in SLI for crunching...
/sd0 /wi3,70,16,2d /sd2 /wi3,70,18,2d
device 1 is /sd0, the other is /sd2...both on the fourth I2C BUS one using register 16 for load, the other card using register 18 for load voltage.
hmmm. I wonder can I use all this for my 8800 GTX? Must see does it have Voltera IC's. Regardless I ran
RivaTuner.exe /ri0,70,1A
RivaTuner.exe /ri1,70,1A
RivaTuner.exe /ri2,70,1A
RivaTuner.exe /ri3,70,1A.
All invalid, for kicks I ran RivaTuner.exe /ri4,70,1A. Screen went white. Restart and it was fine.... *sigh*
Rivatuner voltage adjustment works perfectly with my reference HD4870 512MB. Both overvolting and undervolting is fully functional. Awesome.

I got it working but when both GPU's are set at 100% fan and 1.2v, I get hard locks when overclocking to speeds that are known good with stock volts. The strange thing is that if I only raise the voltage of 1 gpu at a time, I'm fine. I'm wondering if I'm starting to run into power issues - I'm using a Zippy 700w with only 45w on the 12v line, and have 2 GTX 260 Core 16's, an E6850 @ 3.8ghz 1.45v, 4gb ram, 3 hard drives, 9 fans, etc. The 12v line measured with a multimeter is 12.09 idle and 12.08 under load, but still I'm starting to wonder.
I guess it doesn't matter since I have 2x GTX 285's coming soon via step up, but if I'm having power issues with the GTX 260's, I'm certainly going to have them with the 285's. The psu is running at basically ambient temperature due to a dual fan mod on it, but still...
I figured being a zippy I would be okay, but I guess not.

My gosh, are you serious? How much does it help you overclock your 4870 over stock volts overclocking? How much are you able to overvolt it?
I'm so tempted to buy it right now just because of this... (at least, if it can reach 850-900 MHz without hardware v-modding) Is there another thread on this RT voltage adjustment tweak?
