Crucial Ballistix 2GB (2 x 1GB) DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model BL2KIT12864AA804

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: 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.
