Hoping my card will be in tomorrow if not tuesday, we shall see. As long as I can break 1300 i'll be satisfied.

So apparently my cards are the technological equivalent of a 95 year-old women being pumped full of steroids...(seems like a fitting analogy)

Decided to do a suicide run with my CPU at the same settings as when I hit my best score from my sig. Had the AC on in the room for an hour, so ambient temp was 16C, and had the side panel off with a fan blowing into the computer. I set the core voltage at +162mv and PLL at +85mv. Temps were pretty decent for stock cooling, considering voltages. Core on top card stayed under 70C and VRM temp stayed below 60C, obviously fan speed was 100%. Now with unedited AB I ran my sig run at 1320/6950, GPU Score of 23,584. I ran with the above voltage at 1345/6950, and not only was there artifacts (green blotches during 1st and 2nd graphics tests), but I also only scored 23,604 GPU Score. CPU was at same settings as best run, and AB shows full load during all 4 tests and steady clocks.

These must be really be hit and miss as far as reactions to more volts. I would assume water would make a difference, but even so, I keep getting scores almost exact to what I got with both cards 25mhz slower. Did a few runs and always score almost exactly 23,604 everytime. I'd be interested in other's results though for sure.

This means that I can push easily the core to ~1.5Ghz in 3dmark11 with the same voltage ...I like it! smile.gif

man.... go away frown.gif 1432 on less voltage than i take to reach 1350. mad.gif

I'm going to be all about this when i'm on water...temps are much more sensitive in SLI and I can get 1400+ on each of my cards in single card mode (with no hex editing)...running them in SLI forces me to scale back a little for 24/7 operation, gpu2 causes gpu1 to get warmer by about 15c than it does in single card mode.

Those blocks can't come soon enough! As far as doing these voltages on air....you guys are more brave than I am redface.gif

Tooshort: do you have any type of VRM cooling with your universal block?

I just noticed my non L2N bios goes up to 1.28v, and 1360MHz. Sweet.

Are you saying that you get a higher OC with less voltage on your stock BIOS?

Honestly that is where the price should be to start with and with free shipping its closer to $40.00 cheaper now.

HMM I GOT GREEN ARTIFACTS WITH MORE VOLTAGE USING THE MEMORY EDITOR.......I WONDER IF THIS IS GONNA HAPPEN TO ALL USERS. SURLEY THE CHIPS CANT ALL BE LIMITED TO 1350MHZ....... MAYBE ITS HOW WE ARE APPLYING THE VOLTAGE I DUNNO??? WOULD THINK MORE VOLTAGE ALLOWS HIGER CLOCKS

i'm worried that these kepler chips are susceptible to degredation past 1.75v that's why nvidia has locked it down.

Ye but remember, the L has 10x better VRM design then the reference card so you cant compare like that wink.gif

L cards should be perfectly fine in that range....plus your cards at that voltage only during gaming/load, (not really 24/7 far from that) otherwise they are on alot less voltage/clocks, since they downclock.

If you don't use i strongly recommend to use adaptive performance in NVCP and use separate profiles for games/benches for which you can use prefer maximum performance settings thumb.gif

Also your room wil be alot cooler, once i forget into global settings maximum performance turned on, and my card was idling on 40c and before was 29/30 same as ambient, so keep that in mind, i was freaking out before i notice what was the problem biggrin.gif +10 c in 1 day is not a good sign!

This is great tip for all who own Nvidia cards. Never set global profile for max performance.
