Yeah these are great. Use an old cheap Xeon and old memory to do cool stuff.
These are great. If you are looking for a first class experience go with a known brand. But if you are looking for an inexpensive, good board that boots and you can use old parts with to make a powerful little systems, these boards do the job. These are sold under many listings and brands with just a few differences. I bought 2 different ones and the only changes were the colors. I went wild and put 18-core Xeon E2695s on the, paired with 128MB of ECC DDR4 server memory. They run great. I use on to host ProxMox and another as a test box for whatever I want. They are rock stable. Complaints? Sure. It could use another full sized PCI Man it would be killer if I could use a 10gb network card. They do have a short PCI slot. I have purchased some 2.5gb cards that look like they'd fit, but I have not done any testing. I have used a few Chinese market boards over the years. Years ago they used to be usable but pretty rough. They are getting really good, but still a little less developed than well known makes. It is a cheap board, be ok with some stuff if you are buying this.

It's junk, it failed in less than a month, just after the return window. Stay away.
It's junk. I had high hopes to reuse a good Xeon, but the board refuses to POST less than a month into use. Very light use, too, maybe a week total. The jury is still out on other Machinist boards that I purchased, but this one, stay away.

Great value despite no cmos battery
Arrived no manual no cmos battery, installed works great considering price. Replaced a very expensive main board cheap and easy!

This is Motherboard. Also, there's a manual in the listing page.
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.

No Post
Motherboard did not post sadly. Motherboard looks good that's the only thing it has going for itself.

50/50 on v4 support
The first board i received didn't have v4 xeon support so i had to buy a v3 to get it to post i accidentally broke a pin resulting into having to buy yet another board but after doing some testing this one actually booted with my v4 xeon its a hit or miss or you're going to buy this board i recommend sticking to v3 xeons and only try v4 if its all you have since bios updates are almost non existent you just have to luck out with these boards
