Pros: This is a very feature rich board. Allows for up to 256GB of ram, plenty of SATA ports for storage, lots of USB ports. Allows for 4 way SLI or Crossfire. Has the capability to overclock, also allows for memory timing adjustments. Supports the latest 10 and 12 core xeons!
Cons: In order to access battery, the first graphics card has to be removed. Access to CMOS reset jumper somewhat difficult, once again, removal of card in slot is necessary to access. More than 8 ram slots would be nice.
Pros: This board will power a machine exactly as powerful as you'd expect from the components that can be combined on it.
Cons: Very narrow range of acceptable components to build a functioning unit. Requires a very generous amount of power to function properly. Mounting holes do not all align to stock E-ATX holes in a Corsair 750D. Required several small bits of tape to ensure no contact between motherboard tray and the second CPU 8-Pin Power.
Pros: It's fast, lots of SATA ports. 4 way SLI and Crossfire! Able to overclock (well, not much at all because of Intel locking the CPU's down), support for a lot of ram. This is a great board for people who need dual processors but also need to have workstation / gaming video cards. It's also great if you want to add a raid card. I'm using dual 2687W's in here. Very fast!
Cons: This is only minor, but considering that there are other boards out there with 16 memory slots, it would have been nice to be able to install up to 512GB of ram. Cost.... It's expensive! There are other workstation boards out there for less, but few with dual processors and 4 way SLI / Crossfire.
Pros: Dual LGA 2011 Xeons, 4x PCI Express 3.0, Lots of SATA 6.0 ports. Came with second to the latest BIOS as of this review. Using this bad boy for 3D modeling and it does the job done just right. Faster render time nearly cut by a little over 50%. Combine with 32gig of ECC ram and two Intel Xeon E5-2630 this is one killer motherboard.
Cons: None what so ever except for the price but that is to expect from server boards.
Pros: Excellent quality in all the parts. This board is very stable and sexy. I am running it with 2 E5-2687W CPUs and 64gigs @1600 of ram which is the max non-ECC this system can run. When you boot it does take approx 10 seconds for the POST beep. To the guy who said his SR-2 is twice as fast. that's a load of hokum! I get 25.2 on my cinebench test. the fastest cinebench with 2 xX5680s @ 4GHz reached a 20. Search youtube for _aootHB_wR8 and you'll see. I am using 2 corsair...
Cons: First con is a big one. There is no information out there on the ASUS SSD Caching system. From what I've been able to gleen when looking at the SSD Caching on other ASUS mobos you need AI Suite to enable it. At this time there is no AI Suite for the mobo so SSD caching doesn't work. Also there is no MyLogo app for this board (I don't care about that one at all) but when you list these things as selling features you expect them to actually work when you get the board. ...
Summary: If you're like me and you're looking for the absolute fastest workstation (for rendering 3D), then it's best just to spend the money on overclocking an SR-2 with watercooling. That's really the only way you're going to break the intel 2-year speed barrier.
Pros: I've only had this for a couple of days, and truthfully I'm not a big ASUS fan (I've had several other ASUS boards burn out or have bad DIMMS). However, I have to say that this board is changing my mind, in a good way. The BIOS features are robust, and the speed at which Windows 7 ran was outstanding. There is definitely a noticable difference in overall performance over the SR-2 we have (with dual 5680's). So far so good, I'm very happy with this board.
Cons: While the overall performance is awesome, the E5-2690 processor chips we installed only performed about 6% better than our SR-2 system with the 5680s. Which is extremely dissapointing since the cost of the entire E5 system was huge. That's no fault to the motherboard manufacturer, as they have provided great overclocking features on this board... it's intel's fault for locking the CPU so it can't be overclocked past 5%.
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.
