Can anyone tell me what chips are on these modules?

http://www.xtremeddr.com/products/x_pc3700+.shtml

They claim to do 250 FSB @ 2-3-3-6 timings on some mobos.

Also, what are the odds to run this stuff at 2-2-2-6 @ 200 FSB?

Thanks.

On the page you linked:

But are they CH-5, BH-5?

Don't get this RAM by the way, they never run at advertised spec!

BH-5 and CH-5 are types of Winbond chips. These are Samsung chips.
