RAM is showing different speed

This has been abit confusing to me as I purchased this RAM:

6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model 998805

The speed on the specs say 1600 but after I installed it, when it boots up it says 1066 instead. Is there extra steps I need to take?

here's my specs from CPU-z:

Enter to the BIOS and change this things:

CL: 6
tRCD: 8
tRP: 6
tRAS: 24

Set the voltage in auto and test the rig with memtest86+ and prime95 for stability if u get some problem go to the BIOS and change the voltage of the RAM to 1.65V.

Thanks I'll give it a shot. I'll report back with the results. (btw saw you got a CM hyper 212, I have that too. It's amazing, fyi heh)

Yeah, but I'm building my own LCS system for replace my current Hyper 212+ ;)

ok, i noticed that after i changed the memory frequency to 1600 and input the settings you suggested, i noticed my cpu speed went down to 2.6 ghz (im using i7-950 chip) im assuming the cpu is adjusting itself for it? how would i go about keeping my main core speed? though i would like to bring iy up to 4ghz. any tips? also doin the memtest now

edit: seems when i attempt to run the test for single cpu it doesnt do anything else after 3 seconds. then when i try
mutli cpu it doesnt do anything beyond 0 seconds.

This one:

EVGA 141-BL-E757-TR LGA 1366 Intel X58 ATX X58 SLI LE Intel Motherboard

Here's some more shots of CPU-Z


I also took some shots of my BIOS:

(the CPU speed didnt change when I reset the RAM back to the defaults until I did a CMOS reset)

Set the CPU host frequency to auto and theCPU clock ratio to 23.

thatll increase my core to 4ghz and bring the ram to 1600?

As far I know the 950 runs @ 3.06 right?

Set both specifications to auto and the RAM specs as I say up.

unfortunatley that didnt work. my pc wouldnt boot and i had to reset my cmos again

Still having issues with this. is there any specific voltages I should change? Also, I'm not getting any auto setting for the CPU Frequency. I still wanna get it to 4ghz with RAM at 1600
