CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400C4DHX

Pros: Great heat spreaders....overclocks pretty well,currently running at 945mHZ on an Intel BX2 motherboard. No errors, booted right up at its default 1.8V. Upped voltage to rated 2.1V in BIOS and then took off!

Cons: None at all.

Overall Review: Ummmm....this memory, for the chap who complained that it doens't work in Intel boards, has no clue. True, it won't set the EPP settings on an Intel board; but all you have to do is go into your BIOS, and for someone with "high" technical knowledge I'm surprised you couldn't figure that out, and set the timings there. DUH! And for the boy with the center prongs were off, and I guess you mean the notch, this is DDR2 memory, NOT DDR! Of course the notch is off....it's made that way. Either that, or did you even try to turn it around? The notch is off-center, so if you have it backwards, it won't fit. DUH! So many experts, so many dunces.

Pros: Very solid - no errors or install problems at all. Ran Vista memtest - zero errors on 4 GB (two sets of twins).

Cons: SPD is set to the lower specs of the 6400C5DHX (according to Corsair product page). You may want to manually adjust your bios to the 6400C4DHX specs.

Overall Review: Running Vista Ultimate, Intel Core 2 Quad, MSI P6N Diamond MOBO, EVGA 8800GTX in an Antec 900 case w/OCZ 1010W PSU. Vista experience reads 5.9 for everything except this memory. Memory is 5.3. No overclocking - everything is default value. If you have a problem with Vista, install only 2GB first, and then go to 4GB after Vista is configured. Worked for me.

Pros: I bought 2 (2x1GB) for a total of 4GB of DDR2 for my new Vista x64 rig that I built. After installing Vista and downloading the updates so that >3GB of ram could be run, I was able to get things pretty good at the 4-4-4-12 timings.

Cons: If you go to the Corsair site, you'll find out that this memory along with some MBs, mainly Asus, will be kind of touch and go. With 2GB of this stuff, you'll be fine, but as soon as you fill each memory slot with a stick, you might run into issues. Unfortunately, they don't have a 2x2GB set that runs at CAS 4, only CAS 5.

Overall Review: It took some BSODs before I finally got the RAM running smoothly in my Asus M2N-SLI Deluxe. A little patience, running MEMTest+ to be sure that all the sticks were error free, and a bunch of restarts, and I've got my RAM running at the 4-4-4-12 settings that Corsair says it should at the proper 800FSB as well. Make sure to read through their forums in order to get the right settings and you should be ok. Do some MEMTest running to burn it in and stress test it a bit with the settings to make sure it will be stable. Also, make sure that you up the voltage for the memory to around 1.9 - 2.1V, that's what really helped my 4GB run stable. Hope that helps.

Pros: Solid ram, nice looking with the heat spreaders (if you care about stuff like that). Running at 1.9V, 800 at 4-4-4-12 timings.

Cons: Wouldn't post in my Gigabyte P35-DS3L. Thought ram was bad, reset CMOS, nothing. Had to put in a single stick of some other RAM in to get into BIOS and up the voltage. Put these back in and all was good.

Overall Review: Thought these needed the full 2.2V to run at 4-4-4-12 timings. Further playing with memory volts, 1.9V is orthos stable for 12-hours plus 6 passes of memtest. Which still has me scratching my head why it wouldn't post at 1.8V at 5-5-5-15 timings, but whatever. No problems now.

Pros: hGreat price for fast Ram with decently low latency. Hard to find a better deal w/$40 rebate

Cons: Bought 4 sticks so my system would have no compatibility problems. 1 Stick was DOA - heard this complaint before - Newegg was great in RMAing it and a refund is in process - gotta love the Egg.

Overall Review: The heat spreaders are surprisingly high - almost double the height of other RAM - they fit fine in my striker extreme and Antec 900 at present, but I could see how they might get in the way of an aftermarket huge cpu fan, or make cabling a bit messy or complex. On the other hand, as another reviewer pointed out, the heat dissipated by the huge heatsinks probably help to OC them to the max, if you're into that

Pros: What can I say, I popped them in, the booted right up and were read at default speed and timings. Doing what it's suppose to.

Cons: Having to read some knucklehead knock this fine product b/c he bought it from TD and Worldwidereabtes beat him for the rebate. Cry me a rivier, you should have bought them from NE to begin dumm-dumm. Why in the world would someone take a bad expereince from another reseller and come on here and project judgement?

Overall Review: Got these in a Shellshocker for a Visa Card. The sale wasn't clear it was for a Visa card, I thought it was for a straight forty-five dollar rebate. No biggie, IDC, money is money, but you know there will be some emo zit faced kid who will throw a hemmie over it, so I'm just suggesting making it a bit more clear it's for a Visa debit card. and as usual , Newegg is the greatest!!!!!!!

Pros: These are absolutely the best RAM for DDR2 pc6400. Extremely overclockable, even more than the Crucial Ballistix. I thought my ballistix was already fast for doing 4-4-4-12 @ 956 @2.3v. These ram can do 4-4-4-12 @ 1014 @2.3v!!! that's just amazingly fast.

Cons: Aboslutely none.

Overall Review: Remember to put a fan on the ram @ 2.2v and above, so they don't overheat

Pros: High performance memory, does its CAS at indicated voltage. At 1.8V on a Dell E520/E521 machine, it works well. 2.1V is not required for the memory to function. It is only required for the memory to function at designated CAS. If this info helps you, give me a thumb to help other dell (HP, Lenovo, as long as it is 1.8V+) memory seekers.

Cons: For five bucks after rebate, there is nothing to complain.
