Patriot Extreme Performance 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model PDC24G6400LLK

Pros: Works flawlessly thus far at advertised settings.

Cons: Had to manually establish timing and voltage settings through the bios. This was not an issue for me, but may cause problems for the inexperienced or those uncomfortable with bios settings.

Overall Review: You will need a 64 bit OS to fully enjoy the benefits of having 4 gigs. Manually set the BIOS settings if there is any question of stability/performance. Coupled with a G0 stepping Q6600 and Asus P5K-E was able to hit 3.2Ghz on all stock voltages.

Pros: Runs stable at DDR2-667 with 3-3-3-9 timings @ 2.2v, just like its 2x1gb counterpart. Only difference was I had to kick up the tRFC from 27 to 30 or they wouldn't boot. tRFC default on my mobo is 35 with ddr2-800. So anyway I'm happy! Only wish I could keep my old 2x1 sticks in with 'em at these timings, but filling your dimm slots seems like a recipe for trouble.

Cons: ---

Overall Review: So Patriot, how bout some 2x4gb? Trying to skip the whole Nehalem cycle ;)

Pros: Excellent memory, overclocks very well. Very reliable. It DOES work on evga 680i rev A1 @ 4-4-4-12. These people need to learn how to use their motherboard

Cons: Well I use this for every computer i sell, and today i got my first bad stick. out of about 200 sticks, this was my first bad one. Not too shabby.

Overall Review: Get it. Why are you still reading this review? You should have purchased this by now. Shame on you.

Pros: Great stable fast ram. had 4 Virtual machines runing at one time with no problems. Was able to play World of Warcraft, talk on vent, burn a DVD and surf the web with no hang up at all.

Cons: computer is to fast? lol

Overall Review: defaulted to 5-5-5-(forgot) used MB to force 4-4-4-12 and ended up with 4-4-4-10, very likely this is motherboard issue. Definately plan to go for full 8GB. Running AMD Phenom 9850, Vista Ultimate 64bit, Asus Motherboard.

Pros: Ran out of the box with an Abit IP-35 Pro which has default voltages of 1.8v instead of the rated 2.2v. It looks nice and feels substantial.

Cons: Even after upping the voltage, this memory would not run at 4-4-4-12 @ 800Mhz, which are the advertised timings. It was only stable at 5-5-5-12 on my Abit IP35 Pro. I don't think it was the motherboard because I bought the Geil 2x2GB package afterwards and it worked great at advertised timings. If you must have Patriot, buy the cheaper CAS5 memory. It will save you ~$30 and give the same performance.

Pros: Worked perfectly in my MSI P6N Mobo. 2gb X 2. Fast!

Cons: none

Overall Review: The rebate makes it even better!

Pros: Good quality and great price. Runs fast when set properly

Cons: had a 2gb stick die on me when reinstalling vista.

Overall Review: Otherwise great memory, runs great at 4-4-4-12 2.2v on my quad build with asus board

Pros: Great timings! Good heatsinks! A lot better then my corsair...

Cons: Z3r0 >>> This stuff rocks!

Overall Review: Using AMD64 X2 6400+, 4GIG of this stuff, Abit Fatal1ty AN9, XFX 8800 GTX >>> Runs Vista Ultimate like a champ! Games such as WoW run perfect!
