CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400C4

Pros: Runs at 4-4-4-12 @ 2.1V with no errors in memtest 86+ on my Intel 975 XBX2. Should be fine for your average user.

Cons: Probably not for overclocking. Corsair pulled a bait and switch. They used high quality Micron D9 ICs in the early revisions that were sent to reviewers. They then switched to garbage ProMOS ICs that you typically find in el cheapo RAM so they could make more money. This is extremely deceptive and scummy on their part, and probably explains the high defect rate that others are reporting with this memory. I only learned about this recently, and feel a little bit ripped off.

Overall Review: The rebate is nice, but at its core this is basically value RAM that should already be cheap in the first place.

Pros: I Love Corsair, or rather as of yet have been really impressed with them, but...

Cons: I had a DOA. One of the two RAM sticks I had registered over 13,000 Memtest errors. Sometimes it happens, but here I am one or more weeks with out a computer, and that kinda (Really!) bites.

Overall Review: I really wished I would have been one of the luckey ones. Newegg rocks, and I am sure they will take care of me.

Pros: Good fast memory. Works well with my P965 board.

Cons: Make sure you set the correct voltage in the BIOS, or the board/system will not start. Most boards default Vdimm to 1.8V whereas this needs 2.1V. This was very annoying until I figured it out.

Pros: Very fast memory, no errors using Orthos for 20 minutes (I'll stress test it longer once everything else is set up and tweaked) with my GA-965P-DS3 & E6750 @ 3.2ghz, runs at 4-4-4-12 (had to manually set the timing, was at 5-5-5-18 originally).

Cons: I didn't wait for the current price and could've saved $30!

Overall Review: You very likely can't go wrong with this memory, especially considering the price has dropped almost $30 in the last month!

Pros: Awsome stuff it defaults @ 5-5-5-15-2T but runs 4-4-4-12-2T on a stock voltage of 1.8 to run 1T you will need to up the voltage to 2.1 as advertised

Cons: None does what it claimes to do.

Pros: I just bought my second batch of the RAM. I am upgrading from 2GB to 4GB. This ram is rock solid. Performs really well. And for a gamer like me has nice timings and features. Nice compatability with alot of motherboards.

Cons: None

Overall Review: This memory is rated for 2.1 volt operations. Most motherboards have default 1.8 volt settings for DDR2. To get the best performance of this memory you have to adjust the voltage on the motherboard to 2.1 and also have to set the timings to 4-4-4-12 manually.

Pros: Works great at DDR2 800 4-4-4-12-2T. Passed Memtest and Othos 2004 with flying colors.

Cons: I bought 2 of these for a total of 4GB of memory. At first when I installed all the memory, the system wouldn't boot. I then remove 2 of the matched pairs... still wouldn't boot. I took those two pairs out and tried the other two by themeselves. This time, the system booted. Just for the heck of it I tried putting the two I had taken out that didn't work back in. What do you know... system booted. Probably my error the first time and I didn't have these seated correctly (although I swear they were). For those that keep complaining about DOA, try re-seating the sticks. That seamed to fix my issue.

Pros: AM2 motherboards are said to be picky about memory; This one works fine with my ASUS M2N-E. I even achieve the 4-4-4-12 timing with only 1.9V rock solid.

Cons: They ain't cheap...Had to think long and hard about this one but it was worth it.
