**Official 3D Mark 11 scores**

haha your a long way off buddyboy:D

i wonder if cpu multithreading hinders gpu score on this? im clocked above 1200mhz for the gpu yet scores lower?

The strange thing I found was the higher I pushed my CPU, the harder it was to push either of my 680's. If I ran my CPU at stock, it was so easy to reach 13200+ on the GPU but as soon as I get the CPU up to 5Ghz, the GPU would seriously struggle breaking 13K.

Maybe the extra stress on components but no idea. 8 Pack may know.

My 1250 scores were lower also

i think it throttles itself to prevent crashing,it will crash if pushed too hard though

i have the same card as you winston,they are great cards,you have a better card than me i think though

i need to find time to push this card on my z77 system,

I would imagine that the more you push the CPU the more unstable your PCIE lanes become. Remember they are using volts and amps (the PCIE slots).

This used to be a big problem years ago with early Crossfire boards, so they would put a Molex connector above the PCIE lanes to make sure they remained stable when the board was being pushed hard.

I would imagine the only way to help it would be to buy a true high end and top of the range board. Not sure what you are running now btw.

I have the RIVF which has a molex connector for SLI. I am sure you are on to something though. I have tried with the molex in and out and it doesn't make a difference (I keep it in just in case).

I ran with 2 seperate PSU's for each card when massively over volting just in case this would make a difference (pulling 1150W from the wall with everything clocked up).

It is just strange how 1 card with a stock CPU will score considerably more than with the CPU overclocked.
 
@Greg the pcie clock is inside the cpu now making it harder get the gpu stable with high oc on the cpu

@Winston i just run 1050/1375 with stock/no voltage adjustment,tbh theres no need to push for more
