G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRM

Pros: This memory kit is a great value and would perform quite well on INTEL machines. I also think it looks pretty neat.

Cons: In my new Windows 7 system, with a Phenom II 965 140W and ASUS M4A79XTD EVO, this memory booted up fine at first. However, it performed at only 1333 speeds rather than 1600. This wasn't a big deal to me and was something I could live with. However, I turned off the PC overnight and when I started it the next morning it kept rebooting before getting to the log-in screen. I ran Memtest86 and within 20 minutes I already had 2048 errors from this RAM. I decided then that this memory was not suited for my system.

Overall Review: Obviously, as I had read from other people here, this memory is not fit to run with this setup. I returned it and got a different memory kit that works fine. This is nothing against G.Skill, however, since they say it is designed for Intel.

Pros: Running this in an AMD rig myself, but I have friends who've had great luck with this ram in i5/i7 builds. It'll hit rated speeds easily if you follow the specifications as listed on your DIMMs. Note that DIMMs are tested in pairs and can vary slightly, so you may need more or less voltage than others have noted here. You could relatively easily OC these to 900 (ddr-1800) or even 1000mhz (ddr-2000), although honestly there's no need to do so, these @ 1600 or just above will usually hit a 7.9 experience index, depending somewhat on your cpu clock. The spreaders on these modules do work pretty well, you probably don't even need a cooler unless you plan to OC it at some point. The more cooling the merrier, though, I say.

Cons: This could be a con for some -- you do have to go into BIOS to get it to run at the rated speeds (this is a standard thing for quality RAM with lower latency), but honestly if you've never seen a BIOS before you could probably still get it running - these guys are not fussy. Important note for AMD builders - if you've got a Deneb or below, you probably can't run 4 DIMMs (i.e. 4x2 for 8gb) of this at its full speed potential due to a limitation with the onboard mem controller. Thubans can stack 4 DIMMs to whatever speed you can cool.

Overall Review: Running this at standard 7-8-7-24, 1.65v @ 1600, under my old Corsair dominator cooler (go figure) System: ASUS M4A88TD-V EVO doubled my order on these for 8gb AMD Phenom II X6 1090T @ 3.6 MSI Radeon HD5870 Lightning II everything on air, still have plenty of room temp-wise to OC these guys if I wanted to

Pros: its fast memory without a doubt, even running at 1333 mhz.

Cons: if you don't know how to work your bios and are using an amd processor, you should probably pick memory that's compatible with your motherboard. I made the mistake of not doing that and now my memory is running at 1333 mhz instead of 1600. When i tried to change the speed, the system booted up but when I tried to reboot it, it refused to go into the operating system or even post so i had to talk to some people and reset my cmos to get it working again.

Pros: Good timing for DDR3-1600 Low voltage to run, 1.6v Good looking heatsink

Cons: None

Overall Review: Not really a flaw or anything, because AMD Phenom II does NOT support DDR3-1600 unless you overclock the fsb, which cuz me a lot frustration(and reboots) trying to run it at 1600 with the specified timing. (it will just not run at my motherboard with that timing) For my motherboard ASUS M4A78T-E I can run DDR3-1600 with 11-11-11-30 timing. But when the ram running at DDR3-1333 I can tighten the timing to 7-7-7-18 1T without any problem and reduced the voltage to 1.6v. And 3Dmark06 score @ 1600 and 1333 is practically the same 17612 vs 17540 respectively.

Pros: Out of all of this ddr3 kits I've owned these are hands down the best. Many others have come and gone, and I just can't let these go. In fact I'm looking at them right now. They are no longer in service because I needed more capacity, but these babies are jewels. They Overclocked to 2200 MHz at cas latency 7, scoring me the highest benchmark for ram in the history of my computer life. Without exotic cooling.

Cons: 2gb dimms

Pros: Tighter timings than the CL8 ones for virtually the same price. Nice heat spreaders.

Cons: N/A

Overall Review: Bought 2 of these and had to loosen the timings a bit (8-8-7-22) to keep them stable, but I can understand that and cannot dock an egg. Overclocked to 1760ish and running strong for ~15 months.

Pros: Alright, so I jumped on the lowest CL memory I could find at 1600 level. Installed in an AMD system with a 1055T hexacore on M4A88T-M/USB3 mobo. Currently at 1720Mhz with 7-8-7-24 timings and 1.7V. Haven't gone any higher yet, but I anticipate they will hold 1800Mhz with a extra voltage on the IMC. These sticks are performing so far!

Cons: It took alot to figure out how to get these things to perform! I originally ran them at 1.6V since they are rated for it. Everytime I ran Prime95, I would instantly blue screen. Someone suggested to me that this memory will love 1.7V. He was right. For this reason, I want to dink them an egg... but for some reason I'm not.

Overall Review: I wouldn't put these sticks in a cheap system. Considering the extra 'umpph' of sorts it took to get these to perform, make sure you are installing on a decent board with OC capabilities. If you're looking for some good memory for a decent price, get em!

Pros: im one of the satisfied costumer tech support is best

Cons: none
