Kingston 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model KVR800D2K2/4GR

Pros: Very good ram sticks. Very small though, but shouldn't be a problem. I measured it next to other ram sticks i had stored away, they're the same length but half the size. Wouldn't try no overclocking with these.

Cons: None so far.

Overall Review: AMD Phenom II X3 720 B.E. OC 3.2Ghz Stock Cooler Arctic Cooling Freezer 64 Pro will be here tomorrow 6GB DDR2 800 Dual Channel 500GB Western Caviar Black NZXT Tempest Case

Pros: The sticks worked well without problems in my budget build. No errors were detected in two separate RAM tests.

Cons: RAM timings are a bit on the slow side, especially for DDR2 800 speed. CPU-ID detected DDR2 800 mode with timings of 6.0-6-6-18-24. To be honest, this isn't an issue for me.

Overall Review: They are of a shorter height than normal sticks, but that was no importance for my build.

Pros: This ram is AWSOME. I got it before the 7 days dead line on the egg saver and I live 400 miles away from where they shipped it! I put one of the sticks in and it worked took it out and put the other one in and it worked and have been running one for about 1/2 of a week and no BSOD's or anything. I game and research aminly so I look for those all important reviews done by a person who games that bought the porduct and let me says I had 1gb before and running 2gb now and I got more than a double performance increase.I installed just cause 2 the day I got it and I can run IE8 2 tabs,windows MP,7zip,and a few others plus the game and no lag! My games doubled in loading times. I play stuff like MW2,JC2,JC,SUPCOM:FA. And some others. My internet speed got a big speed boost to with this ram.

Cons: Why I only run 2gb when its a 4gb kit is because my top ram slot on my mobo is blown. but it doesn't really make a difference. Its not really a con but just thought I would tell you why just 2gb.

Overall Review: My system is this Windows 7 64-bit Ultimate Asrock N68-S Nvidia 8400GS(i can run just cause 2 on high setting with this card too and at stock!) 480W PSU ANTEC case Kingston KVR800D2K2/4GR(only running 2gb but both sticks work great.:)

Pros: Easily installed and without problems. Highly recommended.

Cons: None

Pros: Popped them in and they work like a charm. No problems at all. I bought 2 sets so I'm running 8 gigs on Win7.

Cons: none

Pros: Its Kingston. Enough said.

Cons: NONE EVER!!!!!

Overall Review: Always work.

Pros: Worked in dual channel mode without any issues Very low profile (lower profile than the clips that hold it in)

Cons: none, really

Pros: Cheap 800mhz DDR2 memory. Installed in Optiplex GX620 machines, works great. Memtest ran overnight with no issues.

Cons: It's not free?

Overall Review: There really is no reason not to upgrade to 4GB of ram. Also it's not important, but these memory sticks are the smallest i've ever seen. The clips for the memory stick up more than the RAM. (A big switch from my usual purchase of high performance ram with built in heatsinks.)
