X99 PR9 LGA 2011-3 Motherboard for Intel Xeon E5 V3 V4 LGA 2011-v3 Socket Processor (DDR4 Max 128GB, PCIe 3.0, M.2 Protocol, SATA 3.0, USB 3.0, Gigabit LAN)

working ok for my needs. I have installed it in a coolmaster box with nvidia 1660ti gpu and a xeon e5-2667-v3 cpu and a 700watt psu. will buy again. it came with 32gb 2133mhz ram with heat shields and boots windows from 3x4 m2 nvme ssd. perfectly..

the best of the best it fits good and looks good and it is good and connectivity and power consumption and stability and love it

I purchased one of these boards and it wouldn't boot with both CPUs. I tried all the normal DIY tech tricks before contacting the manufacturers tech support. I tried to boot with 1 CPU and that worked. So I moved it to the other CPU slot and it worked there too. But if you add the 2nd CPU to either slot, it won't boot at all. It gives a couple meaningless error codes (there's no manual and nothing to download) and then it's bricked. I tried 1 stick of RAM. I tried 2 sticks. 3 sticks. 4 - 5 -6 -7 -8 sticks or RAM. 1 CPU - 2 CPU - 1 video card - 2 video cards - 1 old video card - 1 new video card. Nothing works. So I contacted Amazon and asked for tech support. Amazon got me in touch with the manufacturer quickly. But their tech support was just some person asking me to go back and repeat all the steps I had already attempted on my own. I was expecting some REAL technical support - like a BIOS update or a user manual. I was hoping for a REAL technical support person to offer me some REAL (ya know TECHNICAL) support. Instead I get some person asking me to swap hardware around. I already did that before I ever contacted them. I'd expect a manufacturer to offer some real solutions besides "swap hardware around to different slots until you fool it into booting" They asked me to disassemble it and make a VIDEO of how I assembled it and put it together!!! It's an Extended ATX motherboard with dual 2011-3 CPU's. There is NO WAY to screw it up. The stuff literally snaps into slots and there's only 1 way that each piece can snap in. You CAN'T screw it up. The manufacturers all follow a standard and the components have been "idiot proofed". You CAN'T assemble anything backwards. It won't FIT. Yet, their "tech support" person is asking me to make a video to verify I assembled it correctly. Okay - frustrated as I am - I'll tear it apart AGAIN and make a video of me assembling it. I go to upload the video and there's a 10mb limit. That's when I threw my hands up. After weeks of going back and forth with some useless "tech support expert" I asked Amazon to RMA the darn thing and refund my money. This was nothing but weeks of frustration and a waste of my time.

Nice cheap replacement board for LGA 2011 socket. Running an e5 - 2699 v3XEON 18 core as well as 5820k - verified working. Old school BIOS, no nice looking UEFI; will not read all of the RAM I have (have 64 GB only reads 32, likely BIOS limitation); contains no documentation so you have to use online resources to figure it out. Running 1080ti no problem and can game on old school stuff like Oblivion and GTA V easily.

Works like it should. 32 GB of ram shows up. Very happy with this board. Can't beat the price. Wish the white version had a 32gb ram option.

These are great little "X99"-ish motherboards. Throw a cheap Xeon, ECC RAM and a videocard on and go. I have 2 of these running Linux and use them for hosting KVM machines, Docker containers and game servers. I haven't had any Linux issues with these boards. I have had some kind of weird BIOS issues with old Chinese "X79" boards. The BIOS on these "X99" boards is pretty refined. I say "X99" because I assume these are server and not consumer X99 chipsets, I could be wrong. For almost anyone looking at these it doesn't really mater much. X99 isn't as power efficient as AMD Ryzen, but these make solid little machines. I wish they had 2 full sized PCI slots, but that is about my only complaint.

Motherboard has held up nicely as a replacement for the original that died after 12+ years! Nice replacement MB!

For the money you can't go wrong with this in my opinion. I bought the X99 MR9S model and it works pretty well for me! I paired it with a e-5 2698 v4 and 8x16gb ddr4 2133p ecc server ram. I wanted to make an upgraded server from my previous one while having your standard front panel headers to use a nanoKVM pci-e with it (old server was a dell t410 that has ddr3 and dual xeon x5675). The features/functions on the motherboard are basic. I can't comment on using it for any type of virtualization with it as the server work I do with it is just hosting different instances of game worlds on it via Windows 10 and AMP. The few minor reasons I gave it 4 out of 5 stars is because documentation on this motherboard is very broad and does not answer questions other motherboard manufacturers do with theirs, it has very few fan headers (2 four pin and 1 three pin) and even though it includes a JLPCM slot for a TPM module you have to buy an adapter and a gigabyte TPM module to get it to work and if you reboot the computer you have to do a full power cycle unless you solder 2 wires from the TPM to the motherboard since it does not have the reset pins needed to power cycle the TPM properly. If they had included at least 2 more 4 pin fan headers (could have changed the single 3 pin one for a 4 pin) and included the pins for the TPM reset I would have given this a 5 star review. If I could go back to change my mind for another option (and possibly used) I would still purchase this as it is a great value for what you get.
