Striker extreme & CM2X2048-8500C5D

Hi, I have the Asus Striker Extreme (NVidia 680i SLI Chipset).Today I bought a pair of Corsair's CM2X2048-8500C5D at 1066MHz. But they are not proberly recognized, not in the BIOS & not under CPU-Z. On the POST screen they are displayed as 800MHz & CPU-Z sees them as 400MHz (it should state 533MHz, correct?).Are 1066MHz memories compatible with this board?Is there something I have to do to get thme working at 1066?I used to have a pair of CM2X1024-6400C4DHX (800MHz) for 2 years & they worked just fine.

Here is the CPU-Z log:

Boot to the Memtest CD and allow for two full passes. Shut down replace the first stick with the second stick, reboot to the Memetest CD for two full passes. Finally, shut the system down and insert a stick in slot 1 and slot 3 and boot to the Memtest CD. If stable, enter Windows and post a screenshot of CPU-z's CPU, Memory and SPD tabs.

Hey man,you really heleped me out here!I did exactly what you said and IT WORKED! Check out the screenshots of CPU-Z. The tRas timing runs at 18 even though I set it on 15 as you suggested, but I think thats OK. After 24 hours, the system is stable as before.

Thanks a lot mate. Will post again if I have any news.

Thanks again!
