Which Ram is best for AMD

For 2x1GB, these are probably your best option. I'm pretty sure that the CAS 3 on the PC4000 based on the 500MHz speed, not the standard 400 MHz, so you might be able to take them down to a CAS 2 if you really wanted to.

yea wusy, you'd take the Crucial over the Corsair XMS line? if price isn't an option tho..

lol there's no best it depends on your motherboard and if you OC and how you run them .. timmings what not..

you'll be fine with ocz, corsair xms, crucial... certain kingston's

Best Ram for Best AMD configuration?

If you want to be 100 percent safe you can always check the documentation from the motherboard supplier (if they get it wrong who else is left to trust). Seriusly though, if you don't plan on overclocking or wessing around with the BIOS use PC-3200 memory with low CAS. You can also use the corsair xms chips with auto configuration. If you are planning to overclock, use the ones that have a high speed rating like PC4000. Do not these chips if u aint using it's full potential, that'll hust be a waste of money. Money that you can use for other pieces of hardware, or a couple of dinners. Remember, there is never a clear cut answer to these types of questions, so don't ask again.
