5 out of 5 eggsGreat Board!

Pros: Worked instantly!, That's the first plus. Also, it fits in Xigmatek Elysium perfectly. No bugs, no problems at all. Booted first time, PCI works great for video editing hardware, tried SR-2, but could not make it work with Premiere-Pro with regards to audio I/O hardware. SO video guys beware of the SR-2 trap. Great gamer board, but not for video. This board does it all, you just can't overclock the Xeons.

Cons: No OC

Other Thoughts: Great fit into Xigmatek case, Boot to BIOS screen is about 1:00 minute, then another minute to windows with an SSD.'s a server board with 48GB, so what else is new?

5 out of 5 eggsAmazing motherboard

Pros: I bought this board to build a PC for a software engineering degree. I also bought 2 X E5606 CPU's, 4 X 4 GB PNY registered memory. I put it all in an Intel 5650DP case. I also installed 2 PNY GeForce 450 graphics cards in SLi. I am so impressed with this machine. No beeps bells or loud fan noise.

Cons: There is a chip cooler really close to the first PCIe 16 slot and was difficult to get the graphics card installed

5 out of 5 eggsWorks as expected!

Pros: Works as expected and works with vSphere 4 w/ no problems. I'll probably start migrating to vSphere ESXi 5 some time later this year.

Cons: None.

Other Thoughts: So far, I've built a number of vSphere VMHost servers using this motherboard and haven't had any issues. It is a server motherboard which will require 2 EPS 12v connectors since it supports dual Xeons. Because it's a server motherboard the CPU heatsink holes are threaded and will require purchasing an appropriate fan/heatsink assembly.

I'll probably keep buying this very specific board for cheap vSphere servers until it's either no longer produced or no longer supported for VMware.

1 out of 5 eggsEvil

Pros: Runs 5600 series chips. Decent number of slots.

Cons: Board is programmed to full-throttle fans regardless of thermal temps unless you buy one of Intel's 6 "approved" chassis. Long boot time (1 minute+). Beeps for every attached peripheral at boot (don't ask). Doesn't match ATX hole mounts (only 4 fit). Uses a "CEK" to prevent third-party coolers. Onboard RAID controller won't mount non-raid HDs alongside Raided ones. Pricey.

Other Thoughts: Intel apparently want's to monopolize the market by cornering you into buying only their hardware. Here's why:

1). Although it's an ATX form factor, they use "special" mount locations that don't match standard ATX.

2). A "Common Enabling Kit" blocks the mounting holes for CPU coolers making it impossible to use anything other than the Intel designed coolers. Should be renamed "Uncommon Disabling Vice".

3). The most annoying: your fans will go FULL BLAST, all the time, regardless of CPU load or thermal readings. On page 63 of their platform management PDF, sub-note box it explains why ( This should be printed in LARGE, BOLD letters before buying.

These issues aside, the board works fine. With dual hex-cores installed, it both works and is really fast, however, the degree of frustration due to this board should not be ignored. One month later now, and we're swapping for a com

1 out of 5 eggsLacks Features.

Pros: Intel brand name.

Cons: Bought with matching SC5650WS case. Only has 2 SATA power plugs. Only supports max of 300w of graphics. Doesn't come with VGA connector. Reading reports that if you use nVidia graphics, the case fan goes full blast and sounds like jet on runway. Neither case, CPU's, or mobo includes the the CPU fans. Case power-supply appears cheezy. RAID 5 requires additional parts not included. There are probably several things I'm skipping. By the time you gather all the parts to make this into complete computer, expect a lot of delays, and 50% more money.

Other Thoughts: First time I've been disappointed with Intel in ~30 years. This really isn't a "matched" system like they claim. There is another P/N for mobo+case together, SC5640SCWS? but NE doesn't carry it, nor do any of the shortcomings go away.

I'm not even bothering installing the 2 E5620's and booting it. It's just not complete enough, and 300w with poor nVidia support just doesn't cut it.

I very, very rarely RMA anything. Under 1% a year. But in this case, I guess it's the right thing to do. It simply isn't a "system", it's a Where's Waldo puzzle and I'm not sure Waldo exists.

2 out of 5 eggsVery difficult board to use

Pros: Many features, 4 USB, Firewire 1394, HD sound, SW RAID, 12 DIMM slots, connectors for front panel USB, Firewire, and Sound. Uses an EMI and includes an EMI shell as a boot option. eATX form factor, 2 x16 PCIe slots for potential SLI of Quadro video cards.

Cons: Numerous issues. First, the power is split on either end of the board. The eATX mount holes do not line up with the eATX mount points any of my eATX capable cases. The heat sinks next to the CPU sockets are very close, so close that many heat sinks require modification to fit (I am using liquid cooling). The fan connectors are all at the bottom of the board, save 1, so CPU cooling fans becomes a problem except for the single CPU fan connector itself.

At post the board will elicit a double beep for a connected USB device, then a beep for the system check, then a beep tone for a USB mouse. This sounds very much like an error post when it is not. The status LEDs on my board showed all green however, the board would regularly cut out the PCI slots leaving me with no video or a hung board.

Post times are horrible with an average of 45 seconds before you get a beep and video.

The included drivers are incomplete and dated.

Other Thoughts: I tried multiple light weight video cards (6800 GT series) to make sure the NVidia Quadro 5000 was not pulling too much power, even though the PCIe slot is rated for 300w. The slots seem to have failed entirely now and even though the board passes diagnostics, it refuses to drive any video card I give it.

The post cycle is painful. It tries to use the NIC first, then EFI, then the HD, then the CD by default. Since you have very little time to intercept a boot this board is very time consuming and frustrating to setup.

The cable connection placements are similarly poor and difficult to access relative to any other modern ASUS or similar motherboard.

The documentation is horrible. You get a sticker. Everything else is scattered among multiple PDF files.

There is no live support. You must pay for support unless you are a partner.

This is the 3rd machine I've built this week and this one took me at least 10x longer and in the end, this board failed during burn in.

5 out of 5 eggsWorks

Pros: We ordered this for a new build. It is a very nice motherboard.

A primary reason for picking this board is because it was guaranteed that the BIOS would support the Xeon 5600's series. The model 'R' at the end of 'S5520SCR' indicates that this is the refreshed model and supports the newer CPUs. Other boards from supermicro, for example, do not make this distinction and you may get a BIOS that does not support these new CPUs.

Cons: Post time is very, very long. You'll be staring at a black screen for at least 2 minutes. This was very unnerving on the first boot.

The motherboard has diagnostic LEDs that output a binary number that you can go lookup in the manual for the specific problem. It has an audible bell to indicate other problems. Every boot, our board gives a 3-bell sequence indicating a memory failure, but continues to boot and everything seems fine after the fact.

5 out of 5 eggsIntel 5520SCR workstation board

Pros: I have no doubts that it is the best board in the $400-900 range. The live customer support is excellent. 2-Itel E5520's w/Intel100c heat sink-fans in a Coolermaster 932 w/stock case fans runs w/out problems at 50 Centigrade running Photoshop or Avid.

Cons: valleyedits

Other Thoughts: I would like tyo try the 5520SCR w/2- of the Intel 6-core processors.
