Pros: Speed, stability, price (I got them on sale, so your results may vary)

Cons: None

Overall Review: I've been running four of these modules at 800MHz(x2) at 1.60v with timings of 8-8-8-24-36-2T (the XMP settings) for nearly a month now on an Asus M4A89GTD PRO/USB3 motherboard, with an AMD Phenom II X4 955BE. I've been concentrating so much on software migration issues that I haven't taken the time to overclock anything yet, but the memory stability so far speaks for itself. However, part of the credit for that also goes to AMD for the improvements they made to the memory controller in their C3 stepping (Google "C3 stepping" and "memory controller"). Because of those improvements, I'm able to get the full rated speed and same low latency out of 4 modules as would be expected for only 2 modules, and even at slightly lowered voltage. The only glitch I've seen was when my system made it clear that a 1T command rate was unacceptable (what can I say, I got greedy).

Pros: Now proven 8GB DDR3 upgrade for a 20 month old aircooled 24/7 OC'd eVGA nVidia 790iUltra application. Stable at 1440 / 1.625V / 8.8.8.24 / QX9650 @ 360x10 / confirmed with BIOS P09 & P10.

Cons: The process was quick enough, and your experience may vary, but these would not boot into Vista Ultimate on the slam-dunk first attempt of all 4x2GB installed after removing the previous 4x1GB. In this initial attempt, all 8GB did pass all P09 BIOS level memory tests, but the OS boot errors displayed various inconsistent messages suggesting kernal/hdd issues. I removed 2 modules, and the OS would indeed boot with 4GB in either DIMM pair location. After crossing that hurdle, I simply added the remaining pair, and the next Vista64 boot to fully populated 8GB was troublefree. I'll never know if it was really the rotation of the DIMM pair allocation that was in the mix on this hiccup. This is not a CON for a memory application that is NOT on the EVGA motherboard (or Crucial's) vendor approved list. I chose to take that chance. It is a user experience worth sharing for others who have waited for DDR3 evolution and distribution to catch up with their 790i Ultra capability.

Overall Review: 4x Crucial Ballistix modules work nicely with the Corsair Dominator triple fan. Given time, I may squeeze out faster timing rates. The previously installed 4x1GB Crucial set these replaced ran at 1482 / QX9650 @ 3.7GHz for 17 of the 20 months they were populated. I had to start derating my proven memory timing settings as the mb and video drivers continued to evolve at a Window7 - iCore catch-up pace. Now that nVidia's attention is focused on 2xx series video cards and x58 boards (with 775 socket / 790i ultra / 9800GX2 applications becoming oh-so-April 2008) you might find (like I did) that the never-ending overclocker's driver update experience affects your memory timing and overclocking settings more than the range of memory timing tweaks you initially achieved. I'm happy enough with 1440 in this 8GB application. Finally, that 4x 240pin DDR3 OC motherboard application is maximized for its remaining lifespan, with Crucial's bulletproof, well-warranteed DDR3 1.65V offering.

Pros: Low latency. Great speedy RAM. I had it for about four years and it went bad. I RMA's it to the company because they say it has a limited lifetime warranty. Within less than a week they got back to me no questions asked and just replaced it. In my book that, in and of itself gets five stars.

Cons: It did go bad so that's a con but they replaced it so so what.

Overall Review: I don't remember if I bought it here or not. I just wanted to leave this feedback and say I'm definitely going to buy it again and I'll probably buy these sticks right here on this page. Intel Q8200 4 GB Crucial Ballisix 650 Antec PW Supply 8800GT Asus P5Q SE2

Pros: Super stable memory. Have been using it over a year in my system and I've had no problems at all. Definitely a good buy.

Cons: None.

Overall Review: oh yeah, it looks pretty cool too.

Pros: I've never had a problem with crucial & don't mind that the price is higher than some others.

Cons: Not really con for me,Mother board didn't auto recognize,However if U build your own systems U should know how to set it up without a problem.

Overall Review: As alway NewEgg is top notch in customer service & price

Pros: It's Crucial. I only buy Crucial and Corsair. I've never had problems with either and for that I will always pay a few extra dollars for the memory versus "Joe's Best". Even their lower end, non-ballistix, I've never had a failure.

Cons: None, ever.

Pros: All sticks worked great.

Cons: none

Overall Review: If youre not buying the recommended ram by your mobo youre WRONG. Look at your mobo's tested ram and buy that or something very similiar (ie same brand and as close as possible). There are more timings and other factors at play than CAS and DDR type. If you arent a computer proffessional and dont know how to research that stuff just buy what they test.

Pros: Just another instance where Crucial memory performs as advertised with no problems. I recently installed a 2x2gb kit into an Asus M4A89GTD Pro/USB motherboard with a new AMD 965. The machine booted up just fine and it works well after I set the timings to 8-8-8-24-36-2T 1600. I haven't had any problems at all and really don't anticipate any.

Cons: None.

Overall Review: I've used Crucial for years and have never had a bad stick. Maybe I've just been lucky, but I'm not complaining. I sometimes think maybe I'll try another brand, but after reading horror stories about a bad stick, running hot, or other complaints I always come home to Crucial when it's time to buy. I highly recommend this particular memory in particular and Crucial in general.
