Experience: 10 Days
Good value for DDR2-800 dual channel.
It's purple.
Used in a PVR box. Works fine so far and tested perfectly. I always run a full memory check when installing new memory.

Experience: 1 Years
-stable reliable ram
-great for budget builds
-great timings
-kind of ugly?
Recently retired these in my system but would instantly put them in another build. Easily got to 4-4-4-12 with 2.08v on my EP45-UD3R. With those timings it was very fast and had no issues when it came to gaming. Served me well for over a year, I'm just disappointed that I didn't get more of it so I wouldn't of had to upgrade!

Works good with no issues
No problems yet
Ordered this as inexpensive ram for a HTPC. It's been working great for about a month now and I wouldn't expect anything less from a Corsair product.

Experience: 2 Years

It works with a Striker Extreme
It doesn't cook me breakfast
Ram is ram... but Corsair is worth saying something about. I had a set of these die on me after two years and while waiting for the RMA I purchased another set from NCIX and will now have 4GB.

Corsair's RMA process is awesome. No hassles, quick and easy I got approved by RAM guy on the forums and got a RMA # quickly. They were out of stock so I had to wait two weeks for them to make some more but thats ok.

Oh and I have had lots of problems with ram and striker extreme's... this RAM works flawlessly with this board.

Experience: 1 Months

Good product and good price like everything i bought from Corsair. The only thing i regret is not taking 4GB.

Experience: 2 Years
good price and value
These are a great product. If you are running a 32 bit OS you might as well max it out at 2 x 2GB, and these fit the bill.
Good memory for the price

Experience: 2 Weeks
Great quality, warranty, cheap
You get exactly what it says. It's corsair. Great ram. Install and boot up no problems. Got for $38, $24 with rebate.

Experience: 4 Days

Fast timing
life-time warranty
No overclocking potential, at least what I experienced.
Well, you get what you pay for, if you plan on overclocking your ram don't get these. These are good if you're on a budget though, I got the advertised timing of 4-4-4-12 with v2.1. On a budget, don't need to oc pass ddr-800? These are perfect for you then. Otherwise I'd get something better.

Overall, this is good ram with tight timings. If I had the extra cash i would get something better though just for the option to oc if I needed to.

Experience: 90 Days
Very good price, quality brand, fast timings.
None so far. Just ordered 2 more sticks from another store with a mail in rebate again.
Purchased for my new system with a Athlon X2 Black Edition.

Very fast. Actually this is the best ratio Price/speed/quality right now on the market in my opinion.

Got the mail in rebate in the mail after 3 months. Be patient.
