5 out of 5 eggsGuess I'm Just Lucky...

Pros: Fast-Reliable. I installed this memory about a year and a half ago. Still going strong. Never a problem. I've pushed this memory to its limits several times for increase in gaming performance. Never a glitch. Guess I'm lucky after reading some of these reviews?

Cons: None.

Other Thoughts: I'm buying more! ;)

4 out of 5 eggsGreat RAM

Pros: Works flawlessly
Nice add on with the extra fans

Cons: Cooling fans blow the hot air from the fans back down onto the Motherboard. Some boards have the temp sensor located just around the RAM slots, which will throw off your temp readings.

5 out of 5 eggsOne stick bad but replaced with 4G

Pros: Was replaced under manufacturer warranty with 4G of RAM because they don't make this any more. They actually offered PC2-8500 but it had a latency of 5, so I counter-offered a model of their RAM that was PC2-6400 like this one, but had a latency of 4. That is, if I ever have a motherboard that supports DDR2 RAM at higher than 1.8V.

Cons: One of the sticks of RAM was bad.

1 out of 5 eggsDO NOT BUY THESE - ZERO EGGS

Pros: Well, the timings WOULD be a pro, and that's what seduced me into using these on a build for my parents.

Cons: THEY LITERALLY DIED ALMOST EXACTLY A MONTH AFTER INSTALLATION. I saw other people posting about the ridiculously short lifespan of these modules, but I figured since my parents wouldn't be overclocking or pushing these at all, they should last a normal period of time. WRONG. ONE MONTH they lasted. THAT'S IT. I wouldn't use these to pick my teeth, let alone in another build for myself or anyone. THESE ARE JUNK, OUTRIGHT GARBAGE. DO NOT BUY THESE UNDER ANY CIRCUMSTANCES. Corsair, you ought to be ashamed. I will not buy your products again, EVER, at any price.

Other Thoughts: These were run at suggested timings and voltage, and the included memory cooler was used. There was no fault on the user end. These are just worthless. Worse than worthless. Now my folks are without a decent set of RAM, and they will be stuck using an old pair of DDR-667 (2 x 512MB) modules I had laying around until these get replaced. Nothing but a hassle and an embarrassment. Thanks a lot, Corsair. At least I'm betting I can count on Newegg to make things right, even though it wasn't their fault that they bought junk either.

1 out of 5 eggsNot for 780i boards

Pros: It came with a fan. :)
It says Dominator in the name!

Cons: Timing was very hard to keep at manufacturers specs. I was able to have it run at 2.4v 4-4-3-9 but not 3-4-3-9. Only way to get the timing right was to turn on SLI ready memory mode in BIOS. In the first week I got BSOD, then it was like twice a week, then 4 times a week then, almost everyday. I tried different timings, voltages, and even reinstalling OS ( XP 32bit to Vista 32bit), but no dice. One chip died after about 2 months then 2 weeks later the other.

Other Thoughts: I tried alot of different timing setting to get my computer stable with the RAM. I even went and placed each module in each slot to see if maybe the board was faulty. Still nothing worked. Finally after the first one died I bought some OCZ Series SLI-Ready Edition OCZ2N800SR4GK and now everything works great. Timing is right, voltag is right, and no BSOD. :)

5 out of 5 eggsFan Please

Pros: Handpicked D9GMH Baby!!!
Can run 800 MHz 3-4-3-9 or 1070 MHz 4-4-4-9 need the full 2.4 volts to run these speeds and consequently the fan must be used (even if your case has good airflow).

Cons: D9GMH is no longer made and this is an EOL (end of life product). If they fail, Corsair cannot replace them with the same product.
D9GMH runs quite hot.

Other Thoughts: This is my third set of C3DF. The first two failed after 2 months, but the fan was not used (see CoolBlue review below).

1 out of 5 eggsHorrible Memory

Pros: tight timings..

Cons: Everything... Runs at recommended specs but dies within a month... Everyone who says do not run this at 2.4v is right it will DIE within a month or 2 of use. I restarted my comp and boom bios would not boot, put my old ocz in and booted right up. DO NOT BUY THIS RAM!

5 out of 5 eggsOutstanding

Pros: Bought these 2 years ago for e6600 680i sli system for audio production. Overclocked and never a hicup.

Cons: Price at the time.

Other Thoughts: Toms Hardware had an article and I went with the popular choice at the time. These sticks are great though I don't even remember what they ended up clocking at. Just remember I didn't have to bump the Voltage up to much.

I'm adding another 2 sticks to this system to go with a processor and storage upgrade. It's quality ram at a bargain price. I've studied a few benchmarks comparing DDR3 vs. DDR2 such as this and the difference is very small. It's just so much cheaper to get this and use the other cash to purchase an 8500 and a raptor getting around a 30% increase in overall performance compared to just 3 - 7 % performance for the DDR3 Ram and new MB

2 out of 5 eggsWon't last long

Pros: Worked great for awhile. Price is reasonable for the speed.

Cons: Both sticks died after 3 months of use. This is the 3rd time I've had Corsair memory fail on me. I never OC and still run into problems with their memory. Guess I just keep getting unlucky because all the other reviews seem to praise them.

Other Thoughts: Newegg is the BEST online electronic retailer. I ordered these 3 day standard UPS shipping, received them the next day!
