G.SKILL Ripjaws Z Series 32GB (8 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-17000CL11Q2-32GBZL

Pros: Fast and easy, runs at 2133

Cons: None

Other Thoughts: I installed the memory and enabled xmp on my ASRock X79 Extreme9 and rebooted and it ran like a pro.

Pros: Runs stable at 1866, Good price for 32gig

Cons: Will not run at 2133 with the recommended settings (or any settings for that matter). Will not run stable at 2000

Other Thoughts: This may not be the same memory that I have. I purchased mine on Dec 13 and the specs were 11 11 11 28. Its also $10 less now.

Dear Customer

We are sorry to hear you are having issues with the memory. If you have a motherboard approved for this memory kit, enable XMP and all settings should be properly configured. If your motherboard is not on our approved list, you will need to manually input settings in BIOS. In addition to the basic DRAM frequency, timings, and voltage, you will need to raise the internal memory controller voltage (IMC). The IMC will be overloaded with full slots of DDR3-2133, so you need to boost the voltage so it can be stable with all modules installed. This is why DDR3-1866 is stable (less stress), but not DDR3-2133. There is nothing wrong with the memory, so if you input the proper settings, your system should be perfectly stable. For any questions or issues, please feel free to contact us directly.

Thank you
