DDR2 Corsair PC4300 Value Select - 4-3-3-9

Wow so far I'm impressed with this ram.

@266mhz default: 4-4-4-12

I'm 1 1/2 hours in to memtest with 1:1 4-3-3-9 at 1.90v @ 266mhz and no errors yet. Not bad for $140.00 CAD

I tried lower cas to 3 but got errors 3 passes in.

I think I'll let it go for another 30 min or so and do more benchies.

Using CAS 3 you didn't get errors until the 3rd pass or the 3rd test? If you went through 2 whole passes without error, then maybe see what you can do to improve case ventilation a tad and give it 2.0v. Sounds like you are really close to achieving 3-3-3-8 or so.
