MACHINISTX99 RS9 Server Motherboard LGA 2011-V3 Motherboard for Intel Xeon E5 V3/V4 and Core i7 5th/6th gen Series Processors, DDR4 Max 128GB, SATA 6Gbps, Gigabit LAN, NVME M.2, WiFi M.2, SATA 6Gbps

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 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.

I originally bought this motherboard because I already had a CPU for the LGA 2011 socket and wanted to build a Proxmox server on a budget. It’s been running for 8 months straight with 100% uptime and zero issues. Even though it’s not marketed as a server-grade board, it’s handled 24/7 use like a champ.No BIOS quirks, no crashes, no reboots, just solid, reliable performance. If it can handle continuous server duty this well, it should be a great option for everyday desktop use too.

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.

Great motherboard. I have absolutely no complains in using this for the build i did.

The machinist Motherboard was a piece of crap it never worked and after purchasing three or four cpu's purchased another mb and threw the machinist mb in the trash can. I have never been s I disappointed in my life after spending $105 on the Motherboard

What this motherboard has going for it is that it's cheap. You can get used xeon CPUs and RAM and get a machine that has 32 cores (64 threads) for a few hundred dollars. The build quality is decent, but the board is difficult to work with. The memory slots are really close to the CPU sockets. If you have a fan on your cpus, the RAM will physically touch the CPU fans (or may not fit at all). The eATX board didn't fit the eatx case I bought very well. Not all standoffs lined up with the board. The PCIe slot fit a graphics card, but you can't mount horizontally and support the card weight with a bracket. Contributes to sag. The PCIe slots are really close together, too. So a big graphics card will eat up adjacent lanes. Recommend vertical mounting with riser cables. Also, you aren't getting a manual or support. You get what's in the comments on Amazon. Godspeed you.
