hi

i am using 3930k oc'ed to 4.3ghz and corsair 1600mhz 4x4 16gb ram.

on the fire strike physx score i got about 8844 which is not normal.people have the same cpu with mine get around 12k for the physx score.so can the ram speed 1600mhz be bottleneck for 3930k physx score on fire strike? if yes can please recommend me ram kit with the speed of 2133mhz or 2400mhz from corsair or any other brand and compatiable with x79 dark? but especially corsair ,their customer support is amazing.

I haven't tested Corsair 2133 or 2400mhz DDR3 memory in an X79 Dark but I don't see why it wouldn't work. OK, you didn't state if you had a budget you wanted to stick to, but the models listed here should work (but I can't guarantee it)

hi again guys

after i posted that message ,i checked my scores again when i got home and saw that the pysx score was around 14500.i saw that the score i mentioned above was my combined score.so it seems everything is okay.

and another thing i want to ask is ,for my 980 ti classified at default speeds with the core speed boosted automatically by nvidia to 1350mhz core speed hits the 18800 graphic score.is that normal ?should it be more than 18800 graphic score?

I built my Dark system in December of 2013, and put 16gb of Corsair Dominator Platinum 2133 MHz Cas9 ram in the new build.
 
I could not be happier with this system overall, it has been running rock solid since Day 1 without a hiccup.
 
 

Gskill works amazing on EVGA boards.
