Pros: people that have these in crossfire, what x58MB are you using. Doesn't fit EVGA's E758-TR MB in crossfire

Cons: won't fit all MBs in crossfire due to memory heatsink on backside of card

Pros: One memory kit works and was easily set to correct speed from the XMS profile

Cons: One kit was bad. (bought 2)

Pros: Purchased 3 of these and all are working fine. One installed on a XP PC, one on Vista 32 and last one on Win7. No problems, great connection (300Mps) to my WZR-HP-G300NH. router is in the basement and the PCs are on the 1st floor.

Cons: None so far

Pros: Works great; my old linksys had weak signal on my 2nd floor house, my laptop and Tivo would drop off the network. With this new router both have excellent connection(54Mps) and signal. I also have 3 PCs on 1st floor running 300Mbps on N usb adapters. No issues there either.

Cons: The software/menu isn't very good and I have the A0 A3 that others say have issues upgrading to DD-WRT. I haven't tried to install DD-WRT yet.

Pros: Ordered 2 kits one was fine, 2nd needed RMA; memory errors in memtest.

Cons: RMA'd 2nd kit, New kit now has one stick showing CAS9 and no XMP profile in memory details. CAS9 stick has same sticker as rest saying CAS7/ Now have to RMA this kit.... not happy.

Overall Review: Not sure if Cosair's QA is slipping.
