Look at all the negative reviews at newegg on this ram and choose wisely

I bought this RAM and mine is working fine. I ran 8 and a half hours of memory tests with no errors because I was shocked at all the negative reviews from newegg. I really think I found the culprit of all those negatives though. When mine were shipped to me they came in a box with packing peanuts. Those things had MAJOR static. I am pretty sure a lot of people were getting so much static from those peanuts and then opening the ram that is in a plastic shielding. I made sure I had no static and even sprayed my work area with a solution of water and a few drops of dishwater detergent. YES - I was so worried when I read all those reviews. So maybe I can start off the reviews on here with a positive effect.

This booted up at 5-5-5-18 on a P5B Deluxe which was not hard to change in the BIOS at all. I researched my system and this is what I built and couldn't be more happier. These items go very well together...
Corsair PC6400 RAM, E6600 C2D, EVGA 8800 GTS, P5B Deluxe, and most importantly, I have a 500W power supply in this rig and all seems pretty well, but I would recommend a higher one because of the few BSOD that I have seem when messing around with my system.

One last thing. I have been able to run these at 4-4-4-12, but did get a few errors at 1.8 volts. I recommend the 1.9 volts and more if overclocking these sticks.

Beware what revision you get for OC

This ram comes in flavors from revision 1 to I believe revision 6 (the latest revision I heard about..). I believe after revision 3 or 4 they started using Promo or other crappy memory chips instead of the really good Micron chips. The cheaper ram chips run OK most of the time but the real draw back is that they have shorter life and most importantly DO NOT overclock well at all. So, unless you know you are getting an early revision of these sticks, don't bother. If you really want a memory from Corsair that just runs at stock speeds, then you are better off with the slightly more expensive CL4 versions anyway since they are so much faster.

Great RAM, don't be fooled by bad reviews!

When people complain about the compatibiliy of these sticks they do because they lack the proper knowledge or responsibility to check for compatibility with their motherboards.
These are 1.8V modules and there's a good chance they won't work on a motherboard that supports 2V+. If you overclock them they won't work either... that would be a minus but not for one who knows they are compatible with every 1.8V board.
I for one have a MSI 750i SLI that supports 1.8V and they work fine. They don't run too hot either. If one says they do they must either have bad system ventilation (most of them don't even care to keep a clean cable-free case for a good airflow) or have them overclocked and expect them to run at cool temperatures.
Remember, they don't come with a heat sink to help overclocking them, they come with it to help them cope with the heat they generate at normal usage!

First was DOA, after RMA second worked fine

Cheap. First arrived DOA. RMA . Took three weeks for replacement to arrive. Replacement works fine so far. My first RMA experience with TigerDirect was fairly painless, but paying for shipping twice really kind of sucks.

Giving me bad memories

I will probably be stuck with 2 Corsair RAM after these two bad RAM are replaced and returned to me, but if I had a choice I would not get them again, even though they do look cool.

I wouldn't mind if one, or even both RAMs were DOA, but the situation is worse. The RAM comes with two metal panels on each side for grip (and possibly cooling). Not only was one RAM bad (memtest spotted that one) but the other RAM broke when pulled out of the motherboard. One of the two metal panels just snapped off. It was shocking given how these are supposed to be above average RAM.

I could get some heat sink thermal compound and put it back on but I decided not too because the other bad RAM must go back anyway.

Corsair gets good reviews but this is far from solid, stable RAM. Poor quality control coupled with hardware that part in your hand didn't bold well for me. I ended up going down to the local computer store and buying a set of average common looking 2GB 800 mhz RAM, for less, which worked. Before Corsair can sell their image as a leading brand name they need to up quality control and provide working hardware first, then much better robustness and after that we can talk cool looks.

When I do get the RAM back my system will be 4 GB of memory in total but this RAM experience set me back. I can't comment on performance, as I would have liked to, but to be honest it isn't all about the performance and as you can see not even getting things off the ground result in bad reviews. I will keep you updated on what happens next.

*Update 16th July 2008*
I went through 5 sticks in total to get 2 working ones. That is a 60% failure rate. I would just spend on regular RAM in the future and forget about splashing out for fancy RAM.
