help choosing RAM


Recommended Posts


Here's my configuration:

AsRock Z77 Pro4-M Socket 1155 Intel Z77 DDR3 SATA3 USB3 MicroATX and

CPU Intel Core i5-3570k 3,4GHz Socket 1155 77W .


I have plenty of corsair ram to choose, which one is better?

Basically they are all the same excluding color and the height of the heat spreaders.



The only kits I would shy away from would be the CMP8GX3M2A1600C9 kit because it requires 1.65v for 1600mhz operation and your CPU should only use 1.5v memory.


The CML8GX3M2A1600C9W is a 1.35v kit is also compatible, but I have seen users have to turn around and run them at 1.5v at 1600mhz instead of the 1.35v they are rated at. Not that is the norm...they will run at those spec in some systems just not absolutely sure about your specs.

Not to influence your decision, but wanted to share my experience with this kit. I have tested them on Intel 6 & 7 chipset MSI mainboards, & on two X79's. They are simply amazing in all the tests! Even when tested 4 mixed kits not even close to being matched by serial number or batch/lot in the X79's, they worked better than rated spec with tighter timings (8 8 8 21) & confirmed by DMM DRAM V. @ 1.32v's!


Results I had may not be typical, so no guarantees as peanutz94 had mentioned some systems had to run them 1.50v's. The mixing of kits is not recommended. The difference in performance between 8 8 8 21 & 9 9 9 24 is so small, results will not be detected in everyday use. Buy the rated 1600 Corsair kit that best suits your taste, color, heatspreader design, & price range. :):
