Kingston 4GB 240-Pin PC RAM DDR3 1600 Desktop Memory Model KVR16N11S8/4

Pros: Tested 32GB (4 of these sticks) in both an MSI Z77 motherboard and an ASUS Sabertooth X79 board. Stress tested with Memtest HCI to 1000% with no errors while running Prime95, no BSODs or problems at all. Also tested with Memtest86+ - 15 passes with no errors. This memory seems to have great compatability with the newest Z77 and X79 boards. I wouldn't worry about the lack of heat spreaders, that is just for show anyway. I'd rather have plain looking memory that ran perfect than some fancy Corsair memory with flashy heat spreaders that kept giving me BSODs (been there, done that). Stay away from all other manufacturers and go with Kingston, you'll be happy you did. These are relatively new kits and I hope Newegg keeps stocking them because I would continue to use them for my business.

Cons: No cons!

Overall Review: None

Pros: 1 of 2 RAM modules work just fine

Cons: 1 of 2 RAM modules did NOT work

Overall Review: I ordered (2) and only 1 of them worked, the other was bad. Returning for an exchange, I hope the replacement has better luck. So, that's why I give it 2 stars for trying.
