I've tried running the new CPU with all sorts of combinations, one by one and different dimm slots - the only memory that works is the Hynix, and it doesn't matter what dimm slot I put it in.
The old CPU worked with all 3 simultaneously and one by one.
I can see how the ADATA memory wouldn't work since it has a different clock freq than the Hynix. But how come the new CPU runs with Hynix but not the Kingston memory?
CPU has no integrated memory controller so memory compatibility is about chipset and chipset settings. Try to set FSB to 200/800 MHz and see if it helps.
