It is a balcony mod

At Time we have -6°C outside
Idle Temp of CPU is -4°C
max Temp at Benchmark was 38°C. (RealTemp)

Multimeter shows 1,539V at the first graphic test of 3DMark11. This was the max of all Tests.
Max. Temp was 28 - 33 °C

I am running two GTX680 TOP cards in SLi for some time now. A few months ago i sold one card thinking i wanted to go 2x690, but i didnt and bought a new 680Top card again.
The "old" cards were once provided with the unlocked LN2 bios. No problems with flashing what so ever and also no problems changing back to the original TOP bios.

Two days ago i flashed the bios of the two cards to the NEW LN2 bios (80.04.28.00.3A). Using the same USB stick as i used before, only with the new LN2 bios. It worked fine.
But..when i try to change the bios to ANY other bios file now, it gives me an error. I can see the GPU in the device manager, but it gives a "!". I cant work in Sli and GPU-Z shows one PCIe 16x3.0 and one 16x1.1. Also, when i start my pc, my screen will go blank and say "not connected" and then comes back and works fine..but only with one GPU and with all the mentioned issues..

I've tried installing about 5 different bios files now, including the original TOP bios. I've changed back and forward to different nVidia drivers. But nothing seems to work. The only way i can get back to a perfectly fine working setup, with no errors, no 2 sec blank screen and with SLi, is when i flash to the new LN2 bios wich i mentioned.

I also completely reinstalled Windos. No changes.
Updated the motherboard BIOS. At first i could select SLI setting, but when i apply them, the system freezed and after two attempts.. No changes and the same problems

Any input to figure this one out?

Specs:
3930K
2133 Doms
Rampage 4 Gene
All Watercooled

No one? sadsmiley.gif

Here some tipps for 3DMark 11.

If you set a high LOD, Lightning need a little lower Voltage. I had made so many Tests with 3DMark11.

The best LOD ist a value between 0x00000019 and 0x00000021. Higher or lower LOD takes a lower Graphic-Score.
The max.LOD in Nvinspector you can choose is 3,000. You must edit manually with "0x000000XX".
This scores was i had testing:

LOD = Graphic-Score only!
1,000 = 12318
2,500 = 12798
2,975 = 12892
3,375 = 12984
3,750 = 12330
3,250 = 13011 <-- thumb.gif

Testsystem
CPU = 4,85Ghz
Ram = 9-12-12-12-31 1T
Graka (GTX680Lightning) = 1450Mhz/ 7208

memory bandwidth vs core freq brief comparison

1280c/8000 Mem (+1000)




1306c/7000 Mem (+500)




Seems the extra 500Mhz (1GHz effective) mem contributes about the same in 3DM11 as an extra 26 MHz core freq.
