Serious problem with my Dual Channel RAMs

[kosmiq]

The problem is in the A64 memory controller (the one built into the CPU-core u know)... Currently it can only handle 4 DIMMs if they run at 166MHz.

Using 2xDIMMs gives the opportunity to run at 200MHz.

Future revisions off the A64 core/memory controller may allow 4xDIMMs @ 200MHz. But as it is now, thats a no go.

So it is not the nForce chip that is the problem, it is the memory controller (and as I said it is built in into the CPU).

I would suggest selling the 4x512mb DDR and buy 2x1024mb instead.
