Question 1

This only works with Xeon correct? Not i7 2011? Just wanna make certain.

Accepted Answer

Xeon only. It is a Xeon server mtherboard as it says in the title description...
Additionally, There is no i7 that is capable of the multiple CPU configuration, only Xeon chips have that capability.

Question 2

Can i buy this and run with 1 xeon 2620 v3 cpu? And latter buy the 2nd one and use? Will this work and if does, is there any harm to the motherboard or any other component?

Accepted Answer

Yes this motherboard will run with one processor only.  If you add another physical processor later, you will most likely need to re-install your OS. On Windows Sever, the last time I checked, adding a 2nd processor won't automatically be recognized.

If you use 1-processor only, you will be restricted to 8 memory slots and won't be able to use all of your PCIe slots.  Each processor socket is tied to specific PCIe slots.

I am NOT sure if you can install the one processor in CPU socket 1 or will be forced to use CPU socket 0. It makes a difference because it will determine if you have access to 2 x16 slots or not.

This board is stable and as awesome as the specs suggests.  FYI, I am using 16GB RDIMM (4GB modules) now, but will replace them with LDRIMM later. Pricey.

Question 3

Just purchased the MOBO and have it paired with an EVGA 1300 G2 PSU.  Am having problem when I shut down the computer in Win 10, and then later attempt to power back on I get no power!  No heartbeat LED or nothing.  I'm using a Fractal XL R2 case with only the power switch connected, and find that I must pop the CMOS batter, then reinsert to get the heartbeat and ability to power on.  Does anyone have any ideas?  What PSU may have worked for you?  Supermicro's website doesn't appear to list compatible PSUs...if that is the problem.  Help?

Accepted Answer

Thanks everyone for your help!  I have solved the issue---the main header diagram and the pin numbers illustrated on the quick reference sheet are OPPOSITE of the physical layout of the MB.  I had the power switch pin connector reversed--as I was going by the schematic and NOT what the actual MB is physically laid out.  A quick switch solved the problem!  Thanks again for everyone's assistance!

Question 4

are the Sata cables on this motherboard sata 3 cables or is it just the motherboard slots that are sata 3?

i've been trying to answer this question for 3 mouths now, since this page for buying the motherboard doesn't answer that question.

Accepted Answer

There is technically no such distinction - SATA I, SATA II, and SATA III cables are supposed to be identical, according to SATA specifications.  Lower quality cables might not run at SATA III speeds, but the ones included with this board do, so you'll be fine.

(Side note - while the board is E-ATX size, the mounting holes are proprietary to Supermicro.  Installing it in an a non-Supermicro chassis means you'll need to drill new mount points in your enclosure.)

Question 5

Does this motherboard fit into non-Supermicro E-ATX tower cases?  Reviewers for their dual X9 boards say that they had to customize their cases for it.

Accepted Answer

I tried the corsair 750D case and only 2 screws ligned up... returned it and got the IN WIN 707 BLACK SECC E-ATX full tower Computer Case ATX12V V2.3 / EPS 12V up to 220mm Power Supply. All screws line up and it is a perfect fit for this motherboard. http://www.newegg.com/Product/Product.aspx?Item=N82E16811108464

Question 6

Would this motherboard fit in the Cooler Master Cosmos II case? It is an e-ATX case, but I still feel unsure if it fits

Accepted Answer

I think it should fit. However, not all of the holes may line up exactly. I used a Phantek Enthoo Luxe case and had one hole not line up. Rather than drill a new hole, I just ground the screw part off of one of the motherboard standoffs (the little metal spacer screw thing that you screw into the case and then screw the motherboard screws into are called) for that hole.  The rest of the screws are more than enough to hold the board up during operating conditions, and including ground standoff gives the motherboard a little more support when putting in components/pressing on the board.

Question 7

I'm confused about the CPUs I can use in this mobo. It says it supports "up to 18 cores", but the supermicro website states up to 22 cores -- I want to use dual 2687W CPUs (giving me 20 cores), which are 160W TDP, with noctua NHU9DXI coolers. But, can I not use both of these CPUs, as this board supposedly only supports up to 18 cores? I appreciate any help. Thanks!

Accepted Answer

Sorry, Newegg won't let me link to the motherboard/processor manuals.

According to SuperMicro:

Intel® Xeon® processor E5-2600 v4†/ v3 family (up to 160W TDP **)
Up to 22 Cores† / Up to 55MB† Cache
QPI up to 9.6 GT/s

You don't say what version your processors are, but since you say they have 10 cores, I'm assuming you mean v3.

Processor NumberE5-2687WV3
Intel® Smart Cache25 MB
Intel® QPI Speed9.6 GT/s
# of Cores10
TDP160 W

So, assuming you have adequate thermal support, this should work okay.

Question 8

This doesn't come with CPU coolers does it?
I am thinking of putting 2 x Scythe Mugen 4 coolers on the board but I am worried about the weight. Would the board be ok?
I'll be using a NZXT source 530 case.

Accepted Answer

I run Intel Thermal Solution Air BXTS13A on Xeon v3 2630 2.4Ghz 8-core.   Also nix the NZXT 530 idea with this board. I bought the NZXT after I read Harry's. I had to mod and cut the case like crazy. These aren't standard EATX boards. They are EEATX. I kinda regret the NZXT Source 530 purchase, but I don't have time to get a different one. For your info, I am on the system now. After cutting the case, drives don't fit well. my BD-RE drive is sticking 1.5 inches out in the 5.25" slot because I had to cut the carrier badly to get the board to fit. I also had to make a custom panel for the board to sit/mount on. After that, I managed to get it in and setup.

Question 9

Will this Board support oversize dual 12 inch long Graphic Cards also will the Board support CrossFireX or SLI?

Accepted Answer

I fit a Tesla K40 and an NIVDIA KM5000 onrto  the board with no interference. Also enough room for an additional USB card. However, the X10DAI-O does not support hardware acceleration such as SLI. This is a feature only found on the X10DAX series.

Question 10

Do I HAVE to buy an intel v3 processor? or can I stay with an older/cheaper socket 2011 model and upgrade to a v3 processor later?

Accepted Answer

Yes. Only the v3 CPUs will support DDR4. Older 2011 will not work. They don't support DDR4 RAM, and hopefully intel keyed these differently to stop people from jamming older 2011 CPUs in.  I run dual 2630 v3 Xeons (8-core, 2.4ghz/ea)  You will also need DDR4 ECC Registered RDIMM or LRDIMM. Mandatory
