Viper Xtreme on an Asus P8P67 Pro

Stuck some 2000MHz ram on a Asus P8P67 Pro, but can't get it to boot correctly above 1333MHz

It should run at 1866 ok (as SB doesn't support 2000MHz directly, so should choose the next setting down), but from a cold boot it hangs with the memory LED on the board showing a problem. Reboot at that point when there is already power to the board, and the system works fine. However, power down entirely and reboot, and it hangs again. If I try to autodetect the ram, it only detects it as 1066MHz.

Anyone here using any 1600MHz+ ram on this board with no issues? If so, what make/model?

Are you running auto voltage or have you set it to the voltage on the label. Set up the ram parameters manually.
It will probably default to 1333MHz as that is the max supported intel clock without overclocking the ram in the bios.

+1 to what nkata says

Also, may I ask how many RAM modules you are running? Is it 2 or 4?

I'm running 2x4GB sticks.

I've tried manually setting the correct timings but the results are the same. I've now also managed to try two stick from a friends machine (1600MHz sticks), and the problem persists. With those, if you select auto in the bios, it misidentifies them as 1333MHz. Set them to 1600 and it fails from cold just as mine does. With my ram it doesn't even think they're 1333, but sets them as 1066 if left on auto.

The odd thing is that setting them and then saving and booting is fine - the system boots and is stable. However, power down and then reboot from cold, and it hangs.

It's as if it's trying to redetect the ram itself after a cold boot and failing.

There's also a thread in the motherboard section where someone with the same board has experienced the same failure with Corsair ram.
