I bought 4 gb of G.Skill DDR3-1600 PC3-12800 RAM for my AMD FX-6350 and ASRock Extreme3 R2.0 mobo.

I have windows 8 and the task manager says my RAM is only running at 667 Mhz. WHY?!

It's Dual channel and i have 2 identical sticks that came in the same packaging.

I installed the RAM Properly in slots DDR3_A1 and DDR3_B1 for my motherboard. I don't know what to do.

My friend says it will automatically boost when under load but i've yet to see that happen. It just stays at 667 mhz.

Please help. Thanks.

Go into the BIOS, enable XMP and select Profile 1,,you are running the at the mobo default of 1333

well this did not work. I went changed it to DDR3-1600 and selected profile 1 saved and exited. Everytime Windows started it said it ran in to a problem and said something about a page fault problem. Probably should've wrote the error down. so I had to go to BOIS. there I found that my profile had been set to Auto. so I then, again, changed it to 1600. restarted and found the my ram is still 667 mhz.

Does windows 8 not support it? do I need Windows 8 Pro? That sounds dumb, i know, but i don't know what else to do.

OK, go in and do same then raise the DRAM voltage from 1.5 to 1.55 and raise the CPU/NB (MC (memory controller)) voltage (may also be listed as CPU NB or CPU NB VDD) to 1.22

Well CPUZ or CPUID says's my DRAM Frequency is 800mhz, so it says i AM running at 1600mhz, right? or should i still do what you recommend?

No ;)  you should be good 800 is true freq, it's DOUBLE data rate, so times 2 gives you 1600 effective! Congrat! you've got it ;)

So, could you tell me why Windows Task Manager says I'm running at 667mhz (or 1333 mhz i guess)?

Where abouts? - am guessing that is showing either the mobo default or the default boot freq from the DRAMs SPD

well i also tried moving the 2 RAM sticks to slots 2 and 4. Upon powerup, there was a flash of my LED fans and the system wouldn't power on again. I almost went to my bed to cry, but I figured I go ahead and move the RAM sticks back to slots 1 and 3. the computer worked, I thanked God, and now I'm going to say CPUZ is right and i am running 1600 lol
