disappointments for runing x79z:
1. cannot get more than two of the pcie x16 to work at once, everyone would be fine with x8x8x8x8, or for me even x8x8x4x4 would be fine, but there has been no success whatsoever at gettting more than two of the pcie x16 to work at once, despite the fact this board has four x16 slots
2. No S3 sleep support
3. MSata slot on the board is just for show. does not work at all.
The positives are
1. 8 rams slots (definitely support up to 128gb ram with 16gb rdimm and maybe more if someone with 32gb rdimm willing to test?),
2. has an extra asmedia sata controller for two more sata ports for total of 8 sata ports,
3. works with just about all the cpus including oem 2696 v2... hasn't tried any es v2 cpu but you really shouldn't be getting v2 es cpu anyway.... also works with i7 cpus using udimm only (all the boards i tested so far will only allow i7 with udimm)
