2 out of 5 eggsDOA Stick

Pros: Reasonable price, good specs, lifetime warranty

Cons: Purchased this matched set of 4 x 8gb for a new PC build to be used for CAD and Photoshop with an intel i7 4930 processor. After several hours of struggles to load the op system, we determined that one of the four RAM sticks was DOA. System works fine on 24gb, but as a US expat working outside the US I now need to get a Corsair RMA, return the stick (s?) to the US etc. Not sure what I will do in the interim. Hopefully this was an isolated QC issue.

Manufacturer Response:

Dear Expat Lifer,

5 out of 5 eggsWorking great in my system

Pros: I have had this in my system for a little over a month now and it is running nice and smooth on my EVGA X79 board. I upgraded from a 16GB kit, I needed the power to be able to effectively work on my graphics and video projects for work. XMP profile fits perfectly. Got everything up and running no problems just some minor adjusting to the voltages to crank it up a bit more and I was set.

Cons: So far so good!

2 out of 5 eggsUnderclocker's dream

Pros: Works fine at 1600. Passes memtest86+ and prime95 torture test.

Cons: Does not pass the same tests at 1866. It's advertised as 1866!

Other Thoughts: I tested this memory several times at 1866 in my ASRock FM2A85X Extreme4-M, adjusting timings and voltages. While the machine could boot Windows and Linux just fine, that's no guarantee the memory will stand up to rigorous testing. The prime95 torture test eventually failed every time. I managed to get several hours of success by setting the DRAM voltage to 1.63, but the test eventually failed. Dropped back to 1600 and the memory works like a champ. I would RMA them, but they cost about the same as good quality 1600s from other manufacturers.

My experience with Corsair products has been very good in the past, but not in this case.

Manufacturer Response:
