Corasir MSM 2GB PC-6400 DDR memory

Strengths: Easy to fit

Weakness: One stick was DOA

Only one stick of the memory worked. Returned the purchase for credit - still waiting for my refund. Not happy with this purchase. It has caused problems with my MBoard.

Great Value, performance, service

Strengths: Very good performance, overclock capabilities, warranty service and rebate service.

Weakness: had 1 stick out of last 8 pair I bought go bad

I've bought Corsair memory for the last 3 DDR systems I built. Never had a problem getting a rebate. Yes, they do take some time to print the check and send it back. However, I've even lost a rebate check, called them up and they send me a new one a few weeks later! That's customer service! Performance is always as stated, if not better.

Very good memory

Strengths: Stable and Overclockable.

Weakness: Heat Spreader, I have a fan right on the chips for insurance. If someone got it to 1066 I would be amazed.

Was very happy with this memory, overclocked to at 2.1 volts and 840mhz. It seemed stable at around 850, but above that I started getting orthos crashes. At 840mhz I its very stable.

Corsair wants you (me) to download and unzip a program from I didn't know how to do this so it took some time before a client did this for me. So when the bad module returned 2500000 errors without completing one...

Good Memory

Strengths: Fast memory, easy installation and set up, price, lifetime warranty

Weakness: Heat spreader leaves me wanting, price, reliability?

This memory is very fast, upon initial installation onto an eVGA 680i LT motherboard the system automatically recognized and set up the BIOS settings (easy installation and set up). I put down the price as a strength and weakness because looking at the regular prices it does appear to be more expensive, however I got this memory kit with a rebate (that I'm still waiting on) so the price was very...
