i don't know, but if they do, their re-list will show up in my search alert!They probably want to relist and try to sell at higher price
yeah... and now i'm a bit worried, as in the other Xeon D board thread, the seller I got the Xeon v3 motherboards doesn't seem to have a good rep of selling working boards. I'm ever more anxious to get the components I need to test those boards now...
@RageBone thanks for the offer. They are Gigabyte MD70-HB0 boards. They review on this board here at STH seem really positive. It also seem like a good board not just for server, but workstation build. I was thinking of replacing my ASRock X99EX11 with this dual socket system, once I find the CPUs I want and the DDR4. But for now, I just want to be able to test it and know it works.
@BLinux luckily i do have that exact same board.
Sadly mine is still a bit disabled.
Gigabyte made the interesting design decision to put blocking fets infront of every powersupply voltage rail.
Those unblock once 5V standby is supplied.
On mine, there was a bad cap, shorting 12V EPS to ground on the CPU2.
That somehow killed a few of those fets, taking 5V standby and 5V rail with them down to hell, ehem ground i mean.
Somehow a 5v standby connection broke / burned through and 5Vsb rail from the the 24Pin ATX connector doesn't reach the system.
My fix was to run a wire from that 5vsb 24Pin all the way around the board to a place where there should be 5vsb on a pinheader.
And now it works again.
Only thing still refusing to cooperate is the ipmi, could be a software setting problem, but i havn't debugged that jet, and the 10GbE, it gets hot a s hell but won't appear in lspci and on the network.
Only one port lights up, but no luck on that one too.
Maybe, something killed that controller.
So in any case, i have reference.
And yes the board is a nice one. Even without the burnmarks and the cable. ; )

i have 2 v3 boards that haven't tested yet. just can pray for them are working fine. :/i don't know, but if they do, their re-list will show up in my search alert!

LOL.. that is so not what I need to hear. Can't you just tell me that the MD70-HB0 board is bulletproof? that you once got struck by lightning and everything burned, except the MD70-HB0 board was spotless and booted up with a dead CPU while you were still feeling a bit tingly? That's the confidence inspiring stories I want to hear right now...
@RageBone question for you: do you think it would be enough and/or possible, to test each CPU socket individually? i'm wondering if I can get by with just buying 1x E5-26xx v3 CPU for testing... and just test 1 CPU socket at a time. I will have 1 stick of DDR4 and I'm planning to test it on each DIMM slot per socket.
@BLinux Oh, how did you know i was once hit by lighning ? Holding the Boaard, while it booted a dead CPU with power from the event?
Did burn my hand though, the cpu got very hot very fast. Didn't have a heatsink on.
By the way, has anyone seen my 2618Lv3 ? must have put it somewhere i can't find it any more.
I obviously like the board, its a good board !

i don't know if you can boot it up with cpu only in socket 2.... usually if you have 1 cpu it has to be in socket 1....
Yeah, I don't know... On the older Westmere systems, you could use 2nd CPU socket alone without CPU in 1st socket. I realize the PCI lanes are tied to the CPUs, so some PCI lanes will not work without CPU1...
just wondering if I can get by with a cheaper way to test this board instead of buying 2x CPUs I really won't use other than testing.
Looking over the MD70-HB0 manual page 9:
MD70-HB0 (rev. 1.2) | Server Motherboard - GIGABYTE B2B Service
It looks like CPU0 is tied to the SAS3008, while CPU1 is tied to the X520. But other than that, i haven't noticed anything obvious that would suggest it wouldn't run with just CPU1 and no CPU0. I don't know for sure...
BTW, since you have this board, do you know if these have the hardware to support V4 with a BIOS upgrade?

I have no idea. I don't imagine it would be cheap. I'm located in California, USA if that helps.
was going to pull out my asus z10pe-d16 to test it out but i am thinking it would be the same that it probably won't boot with the cpu only in socket 2...
blinus, you sure you can't get buy with QS/ES cpu also? not that they are much cheaper, just slightly cheaper..
That'd explain why it doesn't work : ) Thanks.
I'm certain that you can get Broadwell Ep runing on that board.
EDIT: @wildpig1234
There is an important distinction btween boots and powers on. Or Posts.
Mine don't even power on to be precise.
Part of the reason might be that the Chipset is only wired directly to the first CPU (0).
Or they all have cpu detect pins in the sockets and need cpu0 to be present to turn on.
