G.Skill Sniper 1600 CAS9 1.25V. My other kit is on loan to a friend, so I got to wait for it to come back before I can get a full 16GB crammed in there
In terms of features, it has a LOT more USB ports on the back (well, just 4 extra ), but that's really it in terms of extra features I can think of...
Maybe the slightly better PCIe allocation from the chipset that doesn't cut off one pair of USB ports based on it's (it's complicated) PCIe lane allocation system the P8P67-M Pro has.
An ASUS rep did state some 240-250W (I don't recall which) power circuitry for the CPU on the Maximus IV GENE-Z...
Also, the m4g has a BIOS reset switch on the back, along with one extra eSATA over the P8P67-M Pro (however, both eSATA are not hot pluggable in the current BIOS ), which have been useful for me.
That's about all I can think of in terms of my useage of both boards. I'm sorry! I'm not really thinking right now.
