Great with a good motherboard

Summary: Thinking I might try to do some future-proofing toward my next big overhaul, I went ahead and bought two of these sets and put my old RAM in an HTPC build I was putting together a couple of years back.
Pros: Fast, reliable, runs at decent temps. Heat sinks underneath large CPU air coolers.
Cons: Expensive, requires good hardware to function properly.
Summary: Memory is sold as what it's highest successful speed, but 9/10 times you will need to enter BIOS and manually adjust timings and voltage to reach that. Read a lot if you are unfamiliar with OCing before trying anything, it's not my fault if you break anything.
Pros: Nice dual channel kit, runs good (now, see cons)
Cons: Initially, CPU-z reported the it had defaulted to 1066Mhz with 7-7-7-24 timings, command rate 1t w/ 1.5V. Changed timings to 9-10-9-27 and added 0.150V for a total of 1.65V and it runs at 1866Mhz (need to OC more for the full 2000)
Summary: I'll be contacting Corsair, and maybe they'll have some magic trick to fix my problem. But it seems people running AMD systems have been having problems with these. Not sure why, but they're supposed to work with it.
Pros: It at least works. And I haven't heard complaints from the Intel Crowd. Was able to get good timings at low frequencies.
Cons: I have been completely unable to get up to the speeds Corsair claims. With some work I've got it running at 1333, and at much worse timings than were claimed in the specs. So, with some work, about half the performance that I paid for. Disapointing, will be considering trying the mushkins or Cruc...
Summary: I could have gone with cheaper sticks and slower sticks, but this is a bit futureproof and OC friendly being so fast; and not having to RMA sticks is worth it in the long run. Some other good makers but I like Corsair the best because of the XMS sticks.
Pros: This memory is beef for my AMD processor. Right now my Zambezi is overclocked from 3.6GHz to a bit over 4GHz and the memory is only running at like 1066MHz. Lots and lots of room for upgrades to future processors running much faster. Having it only run at 1066 the SPD puts it at CL 2 tRCD16 tRP 2...
Cons: The looks could use a bit of work. The Vengeance ones look cooler but these XMS3 sticks dont have heat spreaders that stick up too far or anything (the Vengeance line looks good but I have to wonder about clearance sometmes). I have a closed case without a window so this doesnt matter much to me ...
Pros: I posted that review that mentioned RAM timings of CL 2, it turns out this was an error in CPU-Z the program I was looking at for timings. The actual timings I have are 7-7-7-20 at 4.1GHz CPU and 1.15Ghz memory. Don't know what I was thinking, but still this memory feels fast to me even with more...
Summary: I had the original XMS series, not even DDR2, and it was expensive then, but I have always loved the performance, and overclocking abilities. I had this overclocked along with my other set 44mhz, but bcuz they were mixed sets, I didn't want to take a chance and mess something up, so I backed it down...
Pros: Bought this set to mix with another XMS set that is now deactivated. The set was 2x4gb, 1600mhz, 1.65v with 7-8-7-20 timings. This set, when mixed with the other matches everythang perfectly. Everythang scaled down to match my other ram's every spec. Great for using ramdisk. Crystal Disk Mark 3.0...
Cons: Price. The XMS series has always been highly priced when compared to competing products like Mushkin Redline. For half the price anybody can get 2x4gb (8) but with loser timings. Is the price worth it? I paid for it so I guess I'm the sucker.
