Asus A7S333 and RAM problem

Hi,
Tried to put 2 1gig sticks of ram into mobo and computer wouldn't boot up. Either stick will work by itself or with other sticks (512mb and/or 128mb), but not together. Sticks are made by Advance Modules. People at Asus say I need to change the CAS latency, RAS to CAS delay, RAS precharge time, and RAS active time in the BIOS, but Advance hasn't sent me those numbers yet. The sticks are PC2100 at 266mhz. Any ideas?

Thanks

I would wait on the numbers from Advance and then change them. Apart from that, I don't think there is much else you can do about it at the moment, other run run it with 1gb at a time.

I've been waiting on the numbers for a couple of weeks now. There aren't that many options in the BIOS. I think all of those parameters except the RAS active time give you an option of 2T, 3T, or 4T. I tried 2T but almost got in real trouble when I couldn't even get into the BIOS until I took the 1gigs out and put in the 512. So I'm hesitant to experiment with any of the other settings and I thought someone might have some answers as to what those settings should be.
