G.SKILL HK 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL4D-4GBHK

Pros: Works 100% in my ASUS M4A79 Deluxe/AMD Phenom x4 9850 BE at advertised settings and speeds. Heatspreaders are slightly warm to the touch under load so I know they're doing their job. The HS don't have the chrome clips on the tops but instead have the GSkill chrome logo on the left and the Chrome wave swirl on the front. (see other models to find what I'm talking about) Also came with their trademark graphical sticker to paste on your chassis. Gotta love it ;)

Cons: Stock settings had these at 667 and 4-4-4-12 and Manually adjusted to 800 with no change to timings. No Issues!

Overall Review: Haven't OCed them and probably never will. Now take a moment to compare with me here: C4 @ 800 vs C5 @1066 which is better? Well, do the math and you get about the same number of effective clock cycles 4/800=200 and 5/1066=211. So you get 11 more mem clocks per second with both at least doing 200/sec which is a 5.5% speed increase. Then factor in the "only on one DIMM per channel rule for AMD CPUs" and you're stuck with a mere 2.25% speed gain. Nah, I'll just get the 800 and not deal with the headache ;) As for Intel configurations odds are you're looking at DDR3 so probably not even reading this... :P

Pros: CAS 4 at 1.8V and going strong. Got 4x2 GB of these running in Vista x64 and the memory modules easily let me go to 950MHZ at CAS4 and 1.9V current. Stunning performance at a great price. Could not ask for better chips.

Cons: none.

Pros: - Great timings, nice and tight - Definitely overclocking headroom - Nice heatsinks - Relatively cheap - 800MHz vs 1066MHz is pointless ... for the money and performance gain it is not worth it to get 1066MHz modules - Scores a 7.4 in Windows 7 Ultimate.

Cons: - None so far

Overall Review: I have these running at 1066MHz, with a bit of tweaking and so far so good. This was for testing purposes, I have these in my HTPC so I don't need the extra performance 1066MHz is overrated, getting yourself a decent set of 800MHz memory is cheaper and provides nearly the same performance.

Pros: Put these modules in just over a week ago, running strong since install. Turned on EPP in BIOS and I'm now running 4-4-4-12 at 1.9V under 40C. Super fast, alt tabbing and multitasking, loading levels all faster (compared to 2gb dual channel). Alt Tabbing out of crysis: 2 seconds.

Cons: None

Overall Review: Motherboard: Gigabyte GA-MA69G-S3H I wanted to get the PI version of this RAM but the heatsinks are to large to fit against my CPU heatsink. I'm willing to be this and the PI modules are the same except for the heatsinks and maybe cheaper PCB. Definitely would recommend this RAM to any Gamer.

Pros: Cheap, CAS 4, low voltage, heat spreaders, works great. Popped 'em in my Gigabyte GA-EG31M-S2, set timings to 4-4-4-12 @ 1.8v and away I went. Can't ask for much more.

Cons: Doesn't come in 4GB sticks...yet ;)

Overall Review: The Pi version of this is slightly cheaper (weird?), but I didn't want those ridiculous heat spreaders. These run cool and don't take up any more space than RAM should.

Pros: 4-4-4-12 is nice. Stable when it works.

Cons: ordered 2 sets. 1 set works perfectly with no issues, second set passes pc doctor 7 with flying colors and memtest86 but crashes and bsods while running Aion like nobody's business.

Overall Review: two identical machines: E8400 3ghz 6mb L2 C2D, ASUS p5ne-SLI, BFG Tech gtx260 w/ 216 shaders. No overclocking on either of the machines. Gave 4 eggs for the bad pair. Will RMA on Monday.

Pros: Quick install and the heat spreaders were nice and sturdy. The sticks passed Memtest86+ with flying colors. They run 4-4-4-12 at 1.9 V as advertised. A very nice upgrade.

Cons: None. Buy this RAM.

Overall Review: I installed the sticks in a Zotac 9300 WiFi. I had to manually set the timings in the bios but it was simple.

Pros: These were used in one of Toms Hardware's overclock gaming builds, and they certainly do not disappoint. The heatspreaders are low-profile, so they do the job and do not get in the way. The work well, over-clock without a hitch and even come with a cool, little case sticker.

Cons: In some machines, they will boot-up as a 5-5-5-15, so you will need to manually adjust the settings to get the 4-4-4-12, but that is not really a big issue.
