CORSAIR XMS2 DHX 4GB (2 x 2GB) DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X4096-6400C4DHX

Pros: Performance is flawless. Price is as good as or better than lower quality product.

Cons: The size can be problematic. The total height is roughly twice your normal stick of RAM, and if you have a cooling setup that covers any of your RAM slots you could be in trouble. You do have to manually set the RAM to the faster timing, but it's very easy and the steps can be located.

Overall Review: It's a really good value for really good RAM. Worth it as long as there's no size issues.

Pros: This memory installs easily, and was recognized by Vista as expected. Although not overclocking at this point, it distributes heat well, good for overclockers. Computer has been on for a week straight with no memory glitches yet.

Cons: I can't say this enough....test your memory thoroughly before you install everything (especially Vista). Test each RAM stick separately. I did not and memtest didn't find errors on both at first, but with only one 2GB stick running, errors were immediately found. Corsair has already handled the situation (great cust. service) and I'm back at full strength, no errors either stick now, rock solid performance. Maybe I should look to overclock.

Overall Review: Test memory thoroughly, I spent 2 weeks messing with this new set up and almost gave up, finally ran Windows Memory Diagnostic Tool on each stick separately, finding hardware failure. It CAN happen, and does at times. Do your homework.

Pros: when left alone it runs great, like normal RAM.

Cons: When I set it to the promised 4-4-4-12 timings I couldn't run BF2 for very long before it'd BSOD. I went into Bios and set it back to auto and everything worked. I wouldn't have bought this ram if I knew I couldn't run 4-4-4-12. Very unlike newegg.

Overall Review: I have a very high end gaming system, P5N32-E mobo and everything should supports this RAM. Should have worked at 4-4-4-12

Pros: Works right out of the package. Running Vista 64 bit and recognizes 4094 MB. Very fast, very stable.

Cons: Had a few blue screens initially, but realized that it was because I wasn't setting the voltages/timings correctly on my motherboard.

Overall Review: Use the recommended voltages/timings given by the manufacturer. (4-4-4-12) and 2.1v is what I'm using, works great! Would definitely recommend to anyone thinking about buy it! And of course, NewEgg has the best service!

Pros: Outstanding !!! Work right out of package, Extremely Fast. Windows Ultimate 64bit recognizes it without a problem.

Cons: None

Overall Review: Make sure you set it manually to 4-4-4-12 in your bios, default is 5-5-5-18, and the voltage has to be at 2.1 or it will not work.

Pros: can never go wrong with Corsair... quality product, almost never get a bad stick, when it does happen they have fast, no hassle RMA

Cons: none

Overall Review: moved up to 8G in Vista64 and definitely noticed a speed improvement due to superfetch and more OS in RAM.. at these prices, why not? - note, always check bios to make sure the right voltage and timings are set... dont be a dummy and blame the RAM

Pros: very good memory. fast and good cooling.

Cons: none see, other thoughts

Overall Review: as soon as i put this ram into my pc, everything became unstable. i set the timings to Corsair's stats of 4-4-4-12 with 2.1v. almost sent them back RMA. then did some digging on them. found with my MB, EVGA 680i, there was a fix. set memory SLI to enable with CPU0% and the voltage at 2.0v. set timings to 4-4-4-12-2t. once i did this my system became completly stable. no crashes since. if you are going to OC them then you would have to change your settings accordingly. this would be for non-OC. hope this helps some of you. great memory for a good price.

Pros: I went from 1GB to 4GB :D Have been using it for over a week and no problems. Loads games and programs fast, no stability issues. Went with Corsair because of the quality/stability, plus I had a pair of their RAM before and never failed me in 3 years.

Cons: My motherboard auto-detected at 5-5-5-18, but I was easily able to go into the BIOS and change the settings to set them at 2.1v 4-4-4-12. Computer booted like a charm and no further problems.

Overall Review: This RAM installed fine on an ABIT IP35 Pro motherboard with Arctic 7 Freezer Pro CPU heatsink installed. Apevia X-Telstar Full Tower Case.
