ASUS Striker Extreme & 8GB DDR2

Righty. The facts.

Motherboard is (as best as I can tell) fully working and happy. Its got the latest bios. Its been ticking along perfectly happily for months with 4x 1GB DDR800 (Vdata)

I got 4x 2GB DDR800 (matched by Crucial) Ballistix Tracer this morning.

Plug them all in, and it doesnt tick properly.
Errors have included:
No post.
RAM fail.
Freezing in windows. (Vista Ultimate x64)

I currently have managed to wrestle the bios to some extent (mainly by bumping the memory voltate to 2.25v - which is .25 than the memory spec - and by keeping the SLI Memory function disabled) and its been running for about half an hour so far... But thats just with 2 out of the 4 sticks plugged in.

Processor: Q6600 (not over clocked)


I'm open to any thoughts as to why I can't get 8GB to work?

Cheers.

My advice for you is to open up the documentation that came with your board and take a look at the part saying about having you board stuffed with ram stick on every slot. What speeds do they guarantee you can run? At what voltage? It is a bad idea to use a technical forum as a reference book, try making some research on your own and when you've exhausted your options try with a well formulated question on the right place.
Btw, try lowering to DDR2 667 and you may be successful.
