Summary: I needed a super board to build a power station for Premiere Pro CS6 use. I opted for that board since it is one of the rare board that supported dual xeon while having the options I was looking for. One thing to know off the bat, this is a server board, so it is a odd form factor, I had to change case due to that. It took a while to find a tower that could accept that board and the large size video cards. I use a Raidmax case.
Summary: I love this board. It is my second purchase of this CPU board and I was not disappointed either time. I did have the occasion to talk to ASUS technical support to clarify a driver question and their support was wonderful. Great value, product, and support - the technical trifecta - in my humble opinion.
Summary: I bought this MB for a workstation using 2 Xeon E5 2620 hex core cpus. It works flawlessly with a non standard GTX 560 ti and 8 gigs of ram. I use iray, a host of adobe rendering software, cad, and bunkspeed.
Summary: Don't bother looking for an SSI EEB chassis. Almost all are built for Intel boards where the system will spend its life basking in a dreary, poorly lit computer room while being pummeled by gale force winds from whiny rack style fans. Instead look for water cooled solution from Corsair (the common review), or even better use the Coolermaster 812 with vapor chamber tech to keep your lga2011 xeon 8 core processor cool.
Summary: I had this board with e5-2620 for fixing my pictures and rendering. It took some time to get it going. I still have some starting issues, sometimes it does not start, it has to be turned OFF and then ON again and it takes long time to start. In normal operation hardly any core goes above may be 10%, but when rendering something like 300 pictures at the same time you will see all the 24 cores working around 80% plus mark with amazing speed.
Summary: Like Henry, I've been building high performance workstations built on this ASUS motherboard with E5-2603, 2620 and 2630 XEON's and the board also supports the newer E5 v2 CPU's which boast up to 12 core versions, and I have found it very good in all aspects and very reliable for my clients. Either with 64GB quad channel non-ECC DDR3 or with the full 256GB ECC registered RAM.
Summary: The guy with the paper weight send me an email and I will buy your motherboard firstname.lastname@example.org. Yes, there are problems with the very latest bios, but the bios is on a removable chip you can lever out with a small screw driver and you get bios chips on Ebay for about £10. There are some problems with the GTX 6xx, the don't work in slot 1 but they do work in slot 3.
