Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz (PC3 12800) Desktop Memory 1.5V

does the job.

Most importantly, this memory IS fast, and no errors to speak of with my Core i7-2700K / ASRock Z77 Extreme4 setup. I have not attempted to overclock the chips at all, but for this particular price point, I dont think most purchasers would be interested in doing so (even though it does appear to be supported). Youre buying these chips for value and speed as-is, and it delivers that well.

Bought 2 x 8gb and worked straight out of the box. Started up computer, logged in and there it was - 16gb and works flawlessly.

Works and looks great. The actual available RAM size and RAM speed are correct in BIOS. The RAM might appear as ~15.9 available, but that is to be expected.

Been using them for almost three years, not a glitch.

I now have lots of memory for Photoshop. I had no problem fitting it as my computer engineer son-in-law did it for me. It just works. No problems.

nessun tipo di problema, ottima ram, se si ha il case con finestra hanno anche un bel design, unica pecca magari troppo alte per chi usa dissipatori ingombranti, quindi occhio prima dellacquisto alle dimensioni della vostra configurazione

I purchased these in September of 2017 and one of them has just failed. Worked fine for about seven months and the other one is fine still, but Ive never had RAM fail before, I know it can happen but I still expected to get a bit more time out of these. Spent a few days trying to diagnose why my computer wouldnt get past POST, will check the other RAM first if it happens again.

Work like a charm. No problem.
