CORSAIR XMS3 4GB DDR3 1600 Desktop Memory Model CMX4GX3M1A1600C9

Pros: This ram is Cas 9.. Works Great I may add. My motherboard auto detected at the right speeds. Some motherboard won't ....if the motherboard doesn't, do bellyache and whine, just manually adjust setting in the bios, its not a big deal.

Cons: I can't think of anything to put here.

Overall Review: I accidentally ordered this CAS 9 stick to match a stick in my computer which I later found out to be the CAS 11 version of this stick. When I put this CAS 9 stick in my pc next to the CAS 11 stick already in it, the PC auto detected both as CAS 9 and both sticks run great at CAS 9 speeds... yay for me! My motherboard is a MSI G43 AM3+

Pros: 4GB ram stick
Cheap
Neat design
1600mhz

Cons: One Month Life Spam..
gave me blue screens as soon as i installed. So i moved it to another slot.. it then worked. until it completley crapped out on me just today.

Overall Review: gave me blue screens as soon as i installed. Contacted corsair about how i would return it / replace it via email. Got no response. So i moved it to another slot.. it then worked. until it completley crapped out on me just today. Very dissapointed. :(
