5.0 out of 5 stars Priced so right I got 16Gigs in my computer November 19, 2010
Size Name:8 GB|Amazon Verified Purchase
This is the best deal on the web. Fast & Stable, overclockable to 1600Mhz, and Corsair tech support is helpful and knowledgeable. Best ram purchase I've made in nearly 10 years. At $125.99 from one of these seller, I brought 2 boxes of these ram sticks to future proof my system for the price of 8GB of RAM anywhere else.

My system: AMD X6 Thuban Black edition overclocked to 4.2GHz
Asus Crosshair IV Mobo
Asus 5870 V2 overclocked to 1000 MHz core clock ASUS Radeon HD5870 1 GB GDDR5 PCI-Express Graphics Card EAH5870/G/2DIS/1GD5/V2
Corsair 16 GB Ram overclocked to 1600MHz

5.0 out of 5 stars Great Ram, Great Price. February 17, 2011

Size Name:8 GB|Amazon Verified Purchase
Hi, I got this ram for a Core i7 875K rig. Works perfectly @ 1333 9-9-9-24 speeds. Remember you have to enable XMP or else it will default to 1066 Mhz speeds. I can't wait to buy another 8GB!

5.0 out of 5 stars Works on AMD Phenom II 965 and 1100T April 11, 2011
Size Name:8 GB|Amazon Verified Purchase
There are lots of good reviews on this product, I just wanted to add that it works on my MSI 790GX-G65 and an AMD Phenom II 965 Black Edition. I'm using it with 4GB of Corsair (same model but less capacity), for a total of 12 Gb. No problems - just install and let it rip! I am not overclocking anything, and the CPU cooling is stock.

EDIT: I am now using this with an ASUS Sabertooth 990 FX motherboard and AMD Phenom II X6 1100T, and it works fine.

5.0 out of 5 stars Love Corsair
Bought these because my PNY RAM was causing blue screens. These work perfect. Not blaming PNY the RAM was not on my motherboard support list. The PNY works great in another system.
