It is most likely due to a mismatch of memory sticks. Most motherboards seem to have particular requirements about filling the memory slots with memory. And you must have a 'balanced' setup with matched amounts in the lower numbered slots.

DDR2 is even worse. I don't think you can do DDR2 with an odd number of memory sticks. Which leads to the question of how did you get 7Gig of RAM. I didn't think that 4Gig ram modules were available yet, which imply you have 3 times 2G plus 1G in modules. And the MB does not like the fact that you have 2G in slot 3 and 1G in slot 4.

Try with 6G (3x2) and 5 (2x2+1)...5G *may* work since there would be nothing in slot 4 to cause a problem.

The board is a Tyan server board with 8 slots 2 sets of 4 so... 3 x 1 g + 1 x 1/2 G in each group. Note that M$ had no problem with the memory nor the memory test from the install CD.
