MACHINISIT LGA 2011-3 Motherboard X99 Micro ATX Mainboard for Intel Xeon E5 V3 V4 Series Processors (DDR4 Max 128GB, PCIe 3.0, M.2 Protocol, Gigabit LAN), X99 PR9-H PC Server

I was not expecting much as the dual CPU was inexpensive. I was impressed with the packing and the board looked really nice. You’ll need to have a E-ATX case. Be careful as some cases listed as E-ATX don’t have enough standoffs for this MB. Board posted and booted fine and saw both of my E5-2673V4. I’ve read some reviews that say these fail regularly. I’ll update this review if this board has any issues. Easy to install if you have built PC’s before. Plenty of options for additional ports and fans. So far I’m very pleased with this MB.

Motherboard lasted 10 weeks before an issue with the memory slots around DIMM1 destabilized the entire system. Seller's solution to the problem is copy/pasted below: Dear friend, Thanks for your reply. According to your description, it is most likely a problem with the memory slot. You can send it back to China for repair, but you have to pay for the round-trip shipping. Since the shipping cost is relatively expensive, it is not recommended that you send it back. There is another option. We are willing to give you a 30% refund, or a 30% discount for you to buy a new one. What do you think? Best regards. Remember, this is a 10 week old motherboard and they can't take ownership of the defect or replace it? I won't be buying another MACHINEST motherboard in the future.

Personally, I was not sure what to expect using this very obviously Chinese motherboard, but ultimately I am happy to report it works very well for what it is. There are no instructions, so if you are new to building, you may want to avoid this entirely and go for a name brand. Initially I had a problem with booting, but upon looking up the debug codes, I was able to determine which of my processors I had gotten off eBay were bad. I used Xeon 2667V4's in my build for the clock speed, with attached Noctua NH-D9DX i4 coolers (these are great and keep the processors nice and cool, even if used passive). There are no mini PCIe slots, so if you are using more than one GPU, you will only have access to ONE of the two remaining slots for other add on cards. For me, this was not an issue, as I only required WiFi/BT. The culprits are two Geforce GTX Titan X's causing this to happen, but it makes for an excellent SLI system. This is also an issue for the top of the two m.2 slots... One is blocked/covered by the video cards, so it's not going to get used due to not being able to place a heat sink there. Just as well, the stand offs for said m.2 slots are specific to this board, so good luck finding a replacement if you damage or lose it (I did, so I took a star for this) As others have stated, there are few cases on the market that will support this case, so I put it on a cheap test bench bought here on Amazon, and it works fine since I don't need to move it around. The TPM slot does function with an MSI-based module, but the BIOS will not see it. Which is unfortunate, but not needed in my scenario regardless as it won't support Windows 11 anyway due to the age of the processors used in this board. The board itself is pretty sturdy, has VRM Heatsinks, a chipset heatsink, lots of three pin fan headers. Only one USB header though. Running 64GB of ECC Samsung server memory, works fine, was cheap and new modules can be had on eBay. I may see what the Linux support for it is like at some point, but not yet. Maybe once Windows 10 is expired.

Works for what I bought it for. Runs my dual Xeon server setup flawlessly. Just know that in most cheaper EATX cases the motherboard is so big that it covers some of the cable management channels. I ended up having to route everything through the front . Not a big issue for me as this is just a server, but if you care about looks of your build make sure the case can support it.

Actually way better then I was expecting, works with my Xeon perfectly, documention needs a little improvement but it's running my Linux server perfectly

Motherboard works well. Only got it to use with a xeon processor from this era. only complaints. Back IO sheild did not fit. had to remove it off the board to even get it to fit. The plug connectors will come off and leave bare pins. EX: USB 3.0 pinout plug broke from the board. pins work but just free standing and nothing to lock to. Looking for a cheap board to mess with some high core count cheap xeons, awesome board but don't expect this thing to be a tank. It will get you by. reliability seems fine in terms of a once in a while home lab work horse.

For all the issues I had gone through getting this build working, the motherboard contributed to none of it. It was mostly my stupidity and failure to double check the contents of what I thought was a Windows install USB. To all the people that's saying there's no manual, there is. It's on the listing page. Look for it in the "Product guides and Documents" section in the listing page. Yes, I understand that you aren't shipped a physical one with the mobo. For how much this mobo is, I'm not gonna complain. The supported RAM speeds is DDR4-2133 and DDR4-2400, and nothing else. I'm not kidding. My ONLY gripe is the fact that there's only two fan headers. Put like three more on and you'll get six stars from me.

If I could give it a zero I would, this company should be banned from selling anything on any platform. I have purchased three (3) motherboards from this company Two are the no-name x99 dual processor (pos) one stopped working after a month and the second one out of the box would not post, giving a bad ram error and was unable to bridge the ram for the 2nd cpu. This board I did not pay attention to the seller otherwise would not have purchased it, the board was delivered in a box that looks like rats were eating it, NO cover on the cpu socket and yes thermal paste everywhere.
