I have a problem with my CPU it seems really bad for what it is 4.7Ghz 3930k watercooled in benchmarks

Cine bench
43.95 FPS
807 cb

Geek
14359 points

Instaled with Clover EFI partition, Audio works allright (ALC892), SATA works good

HWMonitor reports 32 multiplier set on all cores, it remains that way no matter the load.
Problem with memory, instead of 12GB is reported 16GB (in activity manager show that all is full)

Using latest Yosemite 10.10.2 updated today 16 March 2015
Having forcefully updated NVIDIA GPU Driver WebDriver-343.02.02f03 - for GTX670 2GB (same statistics on default driver)
Motherboard: -Asus P9X79- (simple, not pro, not WS)

I have uploaded screenshots to help you find more info in them. Hope they are relevant

The system perform allright in desktop, but I will use it for FinalCutProX and other very intensive software and I want to find the problem.

Update 14:01
runing sysctl hw.cpufrequency gives result of 4700000000
Added bios screen configuration

Not sure what you have running, but my "memory pressure" is usually lower than yours (from your screenshot) after a fresh reboot. My guess is that the OS's memory compression is affecting the benchmark. I only have experience with CINEBENCH, but here is the result of my experiment:

To verify this is indeed the issue, try running the benchmark as the first thing you do after a fresh reboot. Or just turn off memory compression out right. You probably don't want Yosemite to do any compression if you use FCP and the likes as the primary functions.

I always run it the first thing, never even tried one benchmark and did not restart after it, but the weird part is that it sees 16gb instead of 12, is that the compression? I think not from what I understand

Update 21:27: I did disable compression, nothing changed, weird that it acts as it is at a default clock, not at 4,7 (as benchmarks)

Update: 21:50 windows test

Update 23:29: I was able to pinpoint the problem, turbo boost not working on Yosemite for me, manually overclocked with turboboost disabled and got 1800 points in geekbench and 1035 in CineBench

2)Installed right AMI
