I had purchase some Kingston HyperX Predator Ram sometime ago, and tonight I was bench testing some coolers for reviews and decided to throw it on my ASRock Z77 Extreme4 3570k Intel bench to play around with it.
This is a 2x4GB stick kit, that is rated to 2666mhz, While I haven't been able to get my motherboard to boot with those freq, I did manage to get it to boot at 2133mhz on the stock timings.
I did some quick benchmarks with AIDA64.
Here are some SS of what I got. Not bad, need to play around with it a little more to get to it the 2666mhz speed its suppose to do.

Here are some MemMaxx Benchmarks
BTW, I am running the 3570k at stock clocks right now so I can narrow down the ram speeds I want. Then I will put the OC back on, This is all the while my 3570k on air cooling and not under water ATM.
