GTX 1080 SLI build need help!

post #1 of 7
Thread Starter 


GTX1080 SLI with such low Valley Extreme HD score. Anybody have any idea?

My CPU is 4930K @ 4.4GHZ. I don't think it is my CPU bottleneck the Video Cards.

One thing I notice is during benchmarking both card is at 79% load instead of 100%.

I have a feeling that CPU is holding it back.
Think I read somewhere Nvidia claimed that even the fastest CPUs today will hold back 1080 SLI.

yeah for sure something is horribly wrong. I am getting 4400ish with a single 1070 overclocked to 2.1Ghz. What bridge are you using? in addition, what 3DMark score are you getting?
From FX to i7

Not only that, the Titan Pascal will be held back in some situations by the CPU, according to Nvidia.

I wonder what the next generation of cards will do. <_<;

My 3DMark Firestrike Ultra 4k score is 10112, which is pretty good. Just the valley score seems really bad.
I am using Nvidia HB SLI Bridge the $39.99 one.
