I've got an Asus P7P55D-E LX with 4 GB of memory, KVR1333D3N9K2/4G. It has been working fine, but now that the memory prices have gone down I figured I might add 8 GB of memory, for a total of 12 GB. However, the Qualified Vendor List of the motherboard lists zero 8 GB sets of memory! Anyone got any idea/experience on whether, for example, one of these would work: KVR1333D3N9K2/8G or KHX1333C9D3B1K2/8G ? For what it's worth I'm running a 64 bit Windows 7 and an i7-870 CPU.
