Looking for answers to a couple of questions

[SpotDancer]

I recently purchased a Tyan Tiger mobo along with two T'bird 1Gig chips. I did a minimum setup - out of the case - the two cpu's w/hsf, Gainward GF2 Pro/450, 2 sticks of ECC Registered (256) ram from Crucial, and a 420W AMD approved PS.

Before I begin, YES!!, T'bird chips will work in a dual AMD setup for those that are wondering.

When I powered the board up, the two CPU fans went on, the fan on the vid card went on, but the system would not post. Nothing on the monitor.

I did a lot of fiddling with the memory chips, tried another vid card, reset the cmos, etc. etc. etc. Still could not get the board to post.

While doing this fiddling I removed all of the memory and the vid card. Reset the bios. Powered up the board with only the two cpus w/hsf. The fans went on. I left the board run overnight. When I got up the hsf's were still running, the heatsink itself was warm....the bottom of the mobo under the cpu's was also warm.

The questions:

1. Will a mobo power up with only the cpu and hsf attached? I was under the impression that a mobo needed some ram and a vid card installed in order to power on.

2. Can I presume that since the hsf's worked and the heatsink and the mobo were both warm, that the two cpu's were recognized by the mobo and were working properly?

3. Is it possible for the fan on a vid card to work, but have something else wrong with it that will cause it not to work - thereby not posting?

Any input will be greatly appreciated.

There are known compatibility problems with Crucial DDR memory. Certain batch of these memory will not work properly with the board unless you fill all four slots.

Have you tried with only one cpu?

Also, do you have another 256 MB . I know that I did not see the Crucial problem when I have 2 alternating slots filled with 256MB module.

I was told that modules with extension ending 265Z1 are known to have problem with 1 or two modules(if 2 modules are placed next to each other)

I have filled all four slots with the memory, and still no post. And, yes all 4 sticks of the memory end with 265Z1.........just my luck....:|

Do you have any answers to my original questions?

With all respect, if the board recognizes both cpu's why would I have to remove one of them to get the board to post? If I did remove one of the cpu's and the board posted - what do I do? Just reinstall the other cpu?

Thanks for the input, and any additional info you can give me............like, is Crucial aware of this "conflict" and could I return these?
