If anyone else has the X79Z VB10 / X79Z B10 motherboard and want this fixed, I encourage you to email the mfg, the rep's name is Sophia:

The more folks that write in about this issue, the more likely it is prioritized to be fixed!
From what I've found out is that you can get a maximum of five slots to work at the same time. But never more than two of the x16 slots.So basically only 2 of the 4 long pci e slots works simultaneously? if you have cards in all of the four x1 slots, would any of the long slots work? that is really screwy....

I think i will ask for a refund...... This is no better than the rest of the other boards with less slots..... I guess the only positive of this board is the 8 ram slots? that's not good enough....Sophia from xlzmotherboard replied to my mail with:
"For this model , about the graphic card, the 4 slots PEI ex16 can't use at the same time, and only 2 slots could use the same time, and others PCI ex1 slots could use the same time, and 5 slots could use at the same time"
I asked if the issue could be addressed by an bios upgrade but the above was her answer to that.
I also got a reply from the seller of the board and it was "problem is design problem".
This problem seems to not be fixable. So I went along and bought a Supermicro X9SRL-F motherboard instead.
The HP Z420 is a also great platform. It has a proprietary PSU but the adapter cable to a standard one is like $15 from amazon. The advantage over the S30 is more HDD/ODD expansion; 3 5.25 bays vs 2 so you can put in a 5x3.5 hotswap in it.Well, if anyone else looking for a good X79 platform, should try the lenovo S30.
I don't think those boards support RDIMM, only UDIMMso i did get this runing x79z to run a 2696 v2 with 128gb ram. so at least that's the good part.
I am testing an Asus P9x79 deluxe board right now. the good thing is it does take a 2696 v2. The bad thing is i am not able to get it to use 16gb ecc ram modules. Asus site says 128gb but i think that's limited to maybe only non ecc ram support by IM ( Intelligent Memory ) memory modules, whatever that means....
I am getting a P9x79 WS board so will see if that's any better. maybe asus restricting 16gb ecc ram to WS boards?... we ll see...
for the X99 platform, I have great single and dual socket boards that support just about all the cpus (even ES) with great ram support and features in the form of Asus Z10PE-D16 and Asrock X99 Taichi.I would say that is the only place they are better.
