CORSAIR XMS2 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model TWIN2X4096-8500C7

Pros: It's 4 gigs of Ram at 1066. Timings for my box are 6-8-8-24.

Cons: Have to overclock to get to 1066 speeds.

Pros: There are MANY pros that I can mention, but there are some that really stick out, here are some: this is a great kit to improve on FPS. Games are COD4MW which was only 40-60 now is 70-110. FFW was 90-110 now maxed at 120 and will not show any higher FPS. there are some other programs that just seem to run smoother, just an over all great kit on the cheap.

Cons: only one little con is that i can not modify the EPP on the chip via the bios nor software, so overclocking is tough but is doable.

Overall Review: Sometimes cheap stuff works better then the more expensive stuff, there is no doubt in my head about that. This kit is great and will always be great. heat is also lower then my old 2gb kit ~29-31C with no extra fans. about ~11-15c with active cooling via KOOLANCEtm. I promise you will not be disappointed!

Pros: Price, perf, I finally got myself a Corsair! It goes to 11 (1066Mhz) on my Asus M3A78-T with no tweaks other than just setting the speed, but see below.

Cons: This is not the RAM's fault so no points taken off - "Due to AMD CPU limitation, DDR2 1066 is supported by AM2+ CPU for one DIMM per channel only" I actually had Patriot 4x1G 1066 that I replaced with these just to get that extra 266mhz. 4x1G set to 1066 would lock up, BSOD, etc.

Pros: So Far, EVERYTHING. The specs on this memory state 7-7-7-20 @ 2.0v My Actuals @ 1066 are: 6-5-6-16 @ 1.8v I've never raised it to 2.0v to OC this memory.

Cons: None

Overall Review: The maching passes Prime95 (24+ hours) @ 6-5-6-16 (on 1.8v).

Pros: fast, cool, and not that much drain of my 450w power supply

Cons: non so far

Overall Review: I recomend this RAM

Pros: Both works well. Were shipped faster than expected.

Cons: Registered as 800mhz, don't know how to change to 1066 in bios, but I'm sure hundreds of people are showing people how to do such a task on internet pages.

Overall Review: Instantaneous 4gb for a low price. I ordered another set to make 8gb total in anticipation of Windows 7 coming out with its nifty x64 architecture. Definitely a wise purchase!

Pros: Great memory. I have had not problems to speak of, and it comes stock set of 800 but all you have to do is change to 1066 in the bios and it works. No heating problems as well.

Cons: None.

Overall Review: I plan no getting another set in the near future.

Pros: very fast and stable. great memory

Cons: none
