Pros: Started off rather dull, yes it can do 800 mhz 4-4-4-12 at 2.2 volts. Then I decided to push it. Got it to a stable 950 mhz 4-4-4-12 at 2.05 volts. Then I slowed it down and tightened the timings. It can run a very stable 750 mhz 4-3-3-9 at 2.0 volts.

Cons: Dislikes mhz pushing compared to timing pushing. At 900 mhz cas4 its only about a 25 percent improvement over normal.

Overall Review: Id rather have the tighter timings than push a speed. The 750mhz 4-3-3-9 benchmarks significantly better than 900 mhz cas 4. Its about 32% faster than the higher clock setting, but both are outstanding.

Pros: Great, high-performance RAM. When I first installed these, I just set the timings in my motherboard (Asus P5N32-E SLI Plus) to "auto." This set the timings at 5-5-5-18. Everything seemed to work okay for awhile, but I started getting intermittent lockups and BSODs. I also couldn't play games like Supreme Commander for more than about 30 minutes without a crash. After some troubleshooting on my video drivers etc., I came to the conclusion that my memory might be the culprit. After some research, I found out that these particular sticks require that you set the timings manually. I went into the BIOS and changed the timings to 4-4-4-12 (2T) @ 2.2V and everything works perfectly. No more crashes or BSODs.

Cons: None, as long as you set the timings correctly.

Overall Review: More expensive that other brands, but I've always been happy with Crucial.

Pros: Easy to install, fast when it works, overclocks very well. I have mine up to a little over 900 mhz at stock timing (4-4-4-12). Crucial has a very efficient RMA process.

Cons: I have ordered this ram twice (for a total of 4 x 1 gb of ram) and one stick ceased to function completely a week later while the remaining 3 all had a problem a month in which seems all to common on forums where the sticks begin to cause random BSOD until you take them out of your computer for a while. Once reinserted, they would work some more but eventually the problem comes back. After RMAing all 4 sticks, the 4 sticks I have now have been working for a couple of months (they sent me slightly different sticks).

Overall Review: If you don't mind RMAing ram then look no further. My friend will probably have to RMA all 4 sticks of his ram soon as well since he has been starting to get random blue screens. It isn't a manufacturing defect that causes this, but a problem with the ram's design. If you have a P35 chipset, then definitely get different ram. If you don't, then it might be worth it to take a chance if this ram is on sale.

Pros: Great Brand...EveryFast.. Runs all my games COD2,B.F,Hitman,Splintercell double agant. and Doom3, and many more all max out with no glitching and loads quick with no hangin or crashing.. Runs vista Home Premium 64bit evryfast..

Cons: Not free, and wont get u laid, Price drop after 3 weeks after getting it.. :(

Overall Review: Im using this ram with the ASUS Crosshair. If anybody was thinking about getting this ram with that board The default is 5-5-5-18 which is easy to change ..... To have it run on the ASUS Croshair here are the setting.. Go in to the bios.. Go in to extreme tweakers.. DRAM setting and set it to.. TCL 4 , TRCD 4, TRP 4, TRAS 12, memory timing 2T.. That make it run 4-4-4-12 @800MHz

Pros: This is my third set of Crucial Ballistix, all have been Great . No problems what so ever Great ram at a good price

Cons: I hate rebates but it was there so i used it . Crucial does send out the rebates unlike some others. I bought a set of these in mid December 07 got my check 1st. of Feburary 08

Overall Review: i don't think you can go wrong here

Pros: Crucial is arguably the best RAM you can buy...and the Ballistix is their elite brand for high performance... I highly recommend it...

Cons: Just like most people reported, by default it showed up on my ASUS M2N32-SLI Deluxe as 5-5-5-18. All it took was a simple change in the BIOS to 4-4-4-12. I left the Voltage on AUTO...and it works GREAT! Just in case you were wondering...the AUTO set it to 1.9volts...

Overall Review: AMD X2 6K Dual Core, ASUS M2N32-SLI Deluxe, 4x1GB Crucial Ballistix (4-4-4-12), XFX 8800GTS, 430watt Thermaltake PSU,

Pros: 4 GB total running stable at 924MHz on 1.8V

Cons: rebate rejected

Overall Review: When you reject my rebate, you don't get my repeat business.

Pros: Abit IP35 Pro sees this ram as DDR2-1066. Don't know whats up with that, but I ain't complaining. It says DDR2-800 on the receipt and the modules. $47 bux rebate makes it a sweet deal indeed! I've left the timing up to the bios for now, which set it at 5-5-5-18. I've only had the IP35 for a few weeks.

Cons: None at this price and performance?

Overall Review: I'm thinking about buying 2gb more even though I'd not be eligible for the rebate again. This is DDR3 performance.
