2nd memory stick problem

[graft123]

Dear all....I hope you can help.

 

Just set up new rig.

 

Runs fine on xp or xp64 with 1 stick of 512mb. :

 

But when adding the 2nd stick,

for xp, won't boot into windows (just the windows start-up screen).

for xp64, get BSOD before booting into windows start-up screen

 

Memory is in dimm 2 and 4.

 

Both work on their own in dimm 2.

 

Can anyone help?

 

Thanks

I have another customer that told me there seems to be a bios update in the works that would support this CPU properly. But this would suggest a bios issue or failing CPU. But I would wait till the new bios is released.
