Supermicro ATX DDR4 LGA 2011 Motherboards X10DRL-I-O

Très satisfait de cette carte mère. Tourne depuis un peu plus d'un mois pour un serveur ESXi.

Overall, I'm happy. This is just now installed in a SC842 Supermicro 4U chassis. My one complaint is that the way the board is laid out, it's impossible to get best practice 'front to back' airflow. Why? Well, if you look at the motherboard diagram, the recommended Supermicro heatsink is big enough that the fan on the side of the heatsink makes it impossible to install the 2nd CPU. I suppose I could have looked for a smaller heatsink with the fan on top, but 2011v3 sockets didn't have a lot of options. Since the SC482 chassis has two 80mm rear case fans right next to one of the CPUs, with half of the rightmost fan not obstructed, I opted for left to right air motion, figuring that the warmer air exiting the heat sinks will get sucked to the rear and exhausted by that one fan. So far, that seems to be working, as the two CPUs are running at barely over 30c.

UPDATE: After getting all my hardware installed, I couldn't get any video output from either my graphics card or the onboard video. I spent a month with tech support each day after work, but we were never able to get any video output. I used two different monitors, which worked on other computers. I enabled and disabled the video output jumper. I tried removing the graphics card and the second CPU... etc. In the end, I RMA'd this board, but the manufacturer said that the CPU pin damage that I incurred while trying to troubleshoot the video output was my fault and I had to pay $50 to fix it. While all that went down, I replaced the motherboard with another dual cpu mobo from another manufacturer and had everything up and running in less than an hour. After trying to explain all this to tech support, they said sorry and that the pin damage WASN'T covered under their manufacturer warranty. I told them to keep the board (and their substandard pin quality) and I would NEVER buy any of their products again. BOTTOM LINE: you get what you pay for, and everything about this board was less than what you would get from a better manufacturer. That includes better packaging (product protection during shipping), better manuals, better bios, better warranty, and better customer service. I won't make this mistake again. This board is listed as ATX on the manufacturer's site, but two of the holes don't line up with the standard ATX form factor and one hole is completely missing. I'd have to drill my Corsair Obsidian case to support this motherboard in the corner next to the external i/o and to support it in the center. My initial impression is disappointed. I'll update this review once I get over this hurdle.

Purchased this mobo along with 128GB of ram and two E5-2620V4 Xeons for OS testing (DragonFlyBSD, but FreeBSD and Linux will also run just fine of course). As expected, this baby screams even with medium-end Xeons stuffed. With the V4 Xeons and I got a nice low-cost machine that came in well under $2000 fully loaded with 16 cores / 32 threads (8/16 per cpu socket) and pretty insane memory bandwidth. A couple of notes. This mobo is what you would purchase if you needed PCIe slots (i.e. for NVMe cards) and an ATX form factor. Most of the non-blade dual-Xeon motherboards fit the larger ATX-E form factor. With this mobo they squeeze it into the ATX form factor which means only eight DIMM slots (four per cpu) instead of sixteen, and one of the PCIe slots is scrunched, but perfectly usable for a short card. Second note is that the mobo has two auxillary power connectors on it rather than one, but connecting a PSU with only one auxillary connector will work just fine if you are stuffing low-end or medium-end Xeons. If you are stuffing a high-end Xeon and/or stuffing multiple GPU cards then get a PSU with two auxillary mobo power connectors instead of one. I don't expect people to buy this mobo for stuffing 16-lane GPU cards, it isn't really designed for that. It's more designed for NVMe cards. If you want to stuff three or four 16-lane GPU cards this is NOT the mobo you want to buy. Finally the mobo does indeed have a dedicated IPMI port, and ipmitool works fine on it. In a server configuration you do not need an expensive cooler, the system runs VERY cool even with everything fully loaded. We test this by doing package bulk builds so literally all system resources are being pounded, and at max load the machine topped out at only 200W (including with 3 NVMe cards stuffed) and CPU temp barely hit 50C. It took a little work with ipmi to configure the fans to not run at full speed (google it for this class of mobo). Remember that these are server motherboards and the fan setup tends to be noisy. If noise is ok, then I recommend something like the Dynatron R30 1.5U Active CPU cooler. Its a low-profile copper heatsink with low-profile fan on the top. Plenty good enough. Be sure the heatsink is oriented for proper front-to-back airflow. This heat sink will probably work fine even with the higher-end Xeons. If noise is not ok then you are on your own. -Matt

Just got this for a friend who wants to do graphic design. So far he's very happy with the results just keep in mind to get a PSU with 2 EPS 12v CPU connectors and 60Hz support. The board is OEM so don't expect any fancy packaging.
