X99 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

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.

As the title states, the motherboard works. I have a Xeon 1650 v4 in it. Boots, recognized PCIe devices, SSD, etc. The VRM were at 112c within a few minutes of booting up, though! (In a system with x5 120mm case fans) Pros: -Automatically recognized the 4 sticks of RAM and went in to quad channel. -Sturdy CPU socket -POST (the barest of minimums) Cons: -The board is kinda short, so the pins for your front panel connectors and such are too close. Even a modest 2 slot GPU nearly covers them and blocks them enough you can't use some of them. -The aforementioned VRM temps. -The only 4-pin fan connection is for the CPU. The system fan headers are 3-pin. I circumvented this by putting all the system fans and the CPU fan on to one SATA-powered hub and plugged that in to 4-pin CPU fan connection. All in all, it's an adequate budget motherboard for X99 that supports quad channel memory. If you're going to put a GPU on it that's 2 slots or bigger, you might have to get creative with your front panel connections and then hope your VRM don't turn molten.

CPUソケットのマウントネジが径が間違っていてクーラーが取り付けられない(ソケット自体は適合)ので返品しようとした所、トランプ政権の通達で海外からの物品送付が実質拒否されていると聞いて怒り心頭。配送業者の対応もあれが足りないこれは受け付けないから書類作り直せとか酷かったが、泣き寝入りするしか無い。アメリカ製品、アメリカ出荷品は二度と買わないと心に誓った。
