OCZ ReaperX HPC 4GB (2 x 2GB) DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2RPX800EB4GK

Pros: Looks great, very stable, overclocks well (got it up to 1066mhz)

Cons: The reviewer below mentioned that the heatsinks aren't much wider than most other RAM, but that is not true. The heatsinks on the sides are MUCH wider than almost any other RAM that I have worked with. I build PC's for a living and I tried this RAM on about 2 dozen different motherboards, and I only found 1 board where 2 of these modules can fit side by side. Most boards you need to leave a slot open in between them, which is fine if you have 4 slots. But if you have a micro ATX board with only 2 slots, or if you want to run 4 sticks of this RAM for a total of 8GB, then you're out of luck unless you happen to have one of the few boards where this RAM will fit in the slots side by side.

Overall Review: By at your own risk if you want to try to put them side by side in your motherboard!!

Pros: Running at 1080mhz 5-4-4-15-2T 2.0v Rock solid for 3 months now. I had no idea 800mhz ram could clock that high and still keep such nice timings. I'm very impressed and have recommended this ram to lots of people over at slizone

Cons: As all the reviews say, the heat sinks are very large, but I can not confirm nor deny that 2 kits will fit. If anything I think they would fit, but it might be a bit of a job to get them in. 4gig is fine for me right now in Vista HP 64bit with the page file disabled.

Overall Review: Q6600 3.24ghz quad core Thermalright Ultra 120 eXtreme 680i LT SLI mobo 4GiG 2x2 OCZ ReaperX OC'd 1066mhz 5-4-4-15-2T 2x8800GTX XFX&EVGA SLI 250gig SATA II 850W SilverStone Decathlon Windows Vista 64bit Home Premium 3dMark06 / Vantage Records : 17668 / 10046

Pros: Runs perfect. No problems with space, but then I am using a behemoth computer case. I can oc it, you can oc just about any RAM, I wanted something large, reliable, and looked nice. This fit the bill.

Cons: Non really, no problems.

Overall Review: Noticed people complaining about these fitting...They fit side by side, by dual channel slots are spaced away from each other so it doesn't matter, but to check it out I placed them right next to each other and they fit.

Pros: Very Fast; Very Over-Clockable; Heatsinks work well, runs very cool. OCZ is the BEST, I've tried other brands with many disappointments, but never a problem with OCZ. I won't switch brands again

Cons: Not any Cons for the memory. But it is annoying when I see the price drop twice in less than a month after I bought it.

Overall Review: Another reviewer complained about a tight fit. I don't see any tighter fit than any other DDR2 with heat spreaders. THe heatsinks are designed to be able to be close as well. However, these are over twice as tall as memory without heatsinks, check your clearance before ordering.

Pros: Great ram good specs. Clocks well. Tight timings.

Cons: Heatsink is big. Hard to fit two sid by side if thats what you want to do.

Overall Review: EVGA 780 SLI Q6600 2 x 8800 GTS 512 SLI Running at 3.8Ghz 20k 3dMark 06 scores!!!!

Pros: Unlike some other heat sinks OCZ has, this is the real deal. No matter what app or game I run when I touch the memory it is still cold. The picks don't do the heat sinks justice, they are very high quality, and are works of art in the right case.

Cons: Yes it might block your other 2 slots, but with 4gigs so what.

Overall Review: THERMODREAM

Pros: great looking. fast

Cons: Huge HS but isnt in the way of anything for me. not a con on my end

Overall Review: WILL WORK SIDE BY SIDE... M2N32-SLI Premium vista edition... have them in slots 1&2... though i did have to bend a transistor a little bit... they fit. wasnt easy but trust me they do fit. If Your like Me and will not take No for an answer. lol, i bought these unaware of the issue so when i read it while they were on the way i panicked a bit when i read people saying they WILL NOT fit side by side. and i never found 1 person say it does..

Pros: im not sure the chipset these use, but they overclock ridiculously easy. i have mine at ddr2 1066 5-5-4 on 2.05V (that's stock!!!). STABLE COOL! simply amazing! i used to use the G.skill with the D9 microns but they were to hot in my craped case, so i got these 2 gig sticks and they are so cool, and overclock better, and for the price AMAZING!

Cons: i couldn't find scissors to cut open the box it came in. ;P

Overall Review: don't by the more expense ddr2 1000 version of these, cause these will easily reach that with stock voltage (they are probably the same ram just clocked differently), you can probably go even faster.
