Experience: 7 Days

Verified OwnerVerified Owner


Works as advertised
Cons A bit expensive


No surprises, works as expected. Used this to replace my OCZ sticks which failed and was reimbursed from warranty as they don't make ram anymore.

Experience: 2 Months


good price for dual channel ram
Cons none


upgrade my old machine with up to 8GB got 2 pack of this runs smoothly no hassle recognize right away recommend.

Experience: 1 Years


Stable, quality name
Cons None!


A decent pair of RAM , have not tried to overclock it but pretty good bang for the buck here. Haven't ever gone wrong with Corsair before, and will definitely continue with them as they continue to produce quality products.

Experience: 17 Days

It's a Corsair. Legendary reliability
Cons none


I added this 4GB to my Motherboard Asus P5K with 2GB RAM and Core2 Duo running at 3GHZ (not much of an overclocker) after upgrading from my very slow loading Vista to Windows 8 Home premium. Wow what a difference Win 8 make when combined with 6GB RAM. Loads in 27 seconds flat. Vista would take over 5 minutes and sometimes lomger just to load and be ready to be used. Could not be happier.

Experience: 30 Days

Verified OwnerVerified Owner


Installed easily. Boosted my older computer running Windows 7.
Cons None


Not much to say other than it worked exactly the way it was supposed to. Boosted my Windows Experience Index memory score from 5.7 to 7.1.

Experience: 5 Months

Good price for this kind of memory
Cons None


This is a good product and the price is ok too. I bought it in promo. Would buy it again. No problem with it so far.

Experience: 3 Months

Verified OwnerVerified Owner


stable, lower temperature than bare chips
Cons not as strong as it looks, can be bend if not careful.


I bought two of these to upgrade my seven years old pc, in the hope of revive it for current games, and it didn't succeed. 8GB DDR2 cost more than 16GB DDR3 and did not make the pc much faster. And also my motherboard having great trouble boot up with maximum ram. 3 out of 10 times it failed post screen.

I finally gave up and put a pair of these in my "Entertainment PC", and let it have bigger cache.

Great choice of ram, highly recommend.

Experience: 5 Months

Verified OwnerVerified Owner


Great value at the time ($55),stable,4Gb, dual channel RAM, lifetime warranty
Cons None far


Bought this with an OCZ vertex 3 Drive to revamp an old Dell Q6600 based PC with 1Gb RAM and a 5400rpm 2Mb cache HD.

The owners are extremely satisfied and the PC got an extended life of at least 2 years for approximately $250.

Experience: 1 Years


Cons none


Got these to upgrade my system to 8gb of ram. Has worked flawlessly since. Corsair makes quality ram.
