DDR compatability issues, any suggestions?

I have 2 Giga-byte GA-7DX MB's. I purchased 2 256MB DDR ECC Registered chips from Crucial, 1 for each board. I wanted to upgrade, since prices are pretty good, so I purchased an additional 256MB DDR ECC Reg Chip from Crucial. However, the 3rd chip crashed my PC (Win 2K Pro). I then began trying different mem combinations (Note: all chips are same specs from Crucial), none worked! I went to Giga-byte site and updated Bios, nothing! All chips work fine alone. The systems only crash when I try 2 chips together. I tried changing bios settings for RAM, but nothing is working. PC crashes everytime. I even tried re-installing O/S, it gave out missing file errors! This is strange b/c all chips are exactly the same! Is anybody else having this issue? Any help would be appreciated. Both PC's are running Athlon T-birds 1.33GHZ AXIA-C, Geforce 32MB DDR, 256MB DDR ECC REG, on Win 2K Pro. Both run great with 256MB chip alone.
 
Why ECC? Not saying that is the problem, but perhaps it might be. I'm not familiar with that mobo, what does the manual say about ECC ram? You may want to try a couple sticks of non-ECC and see if the problem occurs.

I'm just thinking that that mobo may have some known limitation regarding ECC ram(should be noted in manual), or perhaps it has an issue with it's ram slots(possible design flaw).
 
I bought those chips because I figured they were the best. I have not tried non-ECC though. I spoke with Crucial and they told me that the ECC registered would work fine. If I can, I'll see if I can get my hands on some non-ECC. The strange thing is that those chips work fine alone, just not together. I don't get it. Thanks for the suggestion, I appreciate it.
 
Actually, that isn't strange at all. The original MSI DR board crashed with more than one stick in it, and the 7DX isn't supposed to run more than 2 non-registeres, which of course doens't apply to you. I don't know why that is, but maybe the board is having timing issues, try dropping latency to 2.5 if it isn't already.... Maybe that ECC thing, but doubtful, that ram is server quality, it is probably one of the slots on the motherboard. Have you tried solo sticks in each one?
 
Yeah I tried the chips alone and they work fine. I have to try one single one in Dimm 2, but that's why I think it's strange because the Chips work fine by themselves, just not paired up. I'll post an update when I try a chip alone in Dimm 2. I will also try lowering maybe to Cas-2, it is already at Cas-2.5. Thanks for the suggestion,
