4 out of 5 eggsReliable, Flexible, Convertible

Pros: I now have two of these boards (purchased a year apart) and they seem to have consistent manufacturer's specs (in that because I built up the OS drive in identical fashion on the two systems, I can successfully use the OS drive's image from one machine to replace the other's); using 5 SATA HDs with 4 additional HDs on a 3ware AMCC 9550SX-4LP RAID plus a SATA DVD-RW (the ESB2 southbridge beats the Intel ICH9R and ICH10 hands down); teaming of on-board LAN adapters provides consistent 80% utilization send and receive transfers; BIOS is actively being updated and supports the latest Windoze OS; max'ed out both CPUs at 100% continuously for multiple days at a time (once for 7 days straight) without overheating nor noticeable signs of wear and tear even months later.

Cons: Does not include the metal plate required to secure the CPUs to the case; best to go with Supermicro cases because of this motherboard's extra large size and the position of the pin bank for front panel connections; only 4 internal SATA connections are enabled by default, enabling all 6 will prevent hard disk configuration utilities like Acronis Disk Director from working successfully within the OS and also from booting off a disk configuration utility's boot disk (the workaround is to disable the internal SATAs 5 and 6, but of course that means one can't use the hard disk configuration utility on HDs attached to them); a related issue is that I cannot use any type of boot commander but must manually change the partition to active when I want to switch between OS.

Other Thoughts: Everything bought from Newegg. Both machines have an OS drive with Windoze, fruit and penguin flavored OS partitions, each installing and working equally well according to their "specialties" with concessions made to use a legacy video adapter (MSI N8400GS-D512H GeForce 8400 GS 512MB 64-bit DDR2 PCI Express 2.0 x16 HDCP Ready Video Card) and the more compatible network card (NETGEAR GA311 10/ 100/ 1000Mbps PCI Gigabit Adapter with Jumbo Frame support) for non-Windoze OS. They are used as digital audio workstations (DAWs) with non-linear video editing capabilities.

5 out of 5 eggsSolid board

Pros: Some reviewers have had issues with only 4 SATA ports being active. You need to enable SATA RAID in the BIOS to activate all 6 Ports. All 6 Ports will run fine as JBOD with SATA RAID enabled. I am very happy with this board. Running it in a 745TQ-R800 Supermicro chassis. No problems. My experience has been the Supermicro boards work great in Supermicro cases.

Cons: no onboard video

Other Thoughts: My setup:
Supermicro 745TQ-R800 Chassis

Dual Intel Xeon E5410 Harpertown 2.33GHz 12MB L2 Cache LGA 771 80W Quad-Core Processor

Crucial 2GB 240-Pin DDR2 FB-DIMM ECC Fully Buffered DDR2 667 (PC2 5300) Server Memory

SAMSUNG Spinpoint F4 HD204UI 2TB 5400 RPM 32MB Cache SATA 3.0Gb/s

1 out of 5 eggsNever again SuperMicro

Pros: Who cares.

Cons: I will never again buy a SuperMicro product. I ignorantly deducted that buying a case and MB from the same supplier would make the building process smoother. How stupid was I.

Instead of planning on buying an aftermarket cooling solution, since SuperMicro made sure you can't use the one that comes with the chip that THIS BOARD IS DESIGNED TO USE, I suggest you do yourself a favor and buy another board.

If they suck so bad they can't even get the right mounting solution for the chip btw. their case and their MB, then they do not deserve your business.

Other Thoughts: I can't wait to find out everything else wrong with this board.

5 out of 5 eggsVery Impressive

Pros: Built a second system with this board. It runs 100% stable with no issues or problems.

Cons: It's a huge board. But, when you buy this you expect it, right?

Other Thoughts: 32 gigs Crucial DDR 2 FB DIMMs, dual X5482 Xeons (these are thermonuclear reactors), ATI Radeon 4870 x2, Areca ARC 1280ML-2G, 4 500 GB WD in RAID 0, 5 Seagate 1.5 TB in RAID 6, 4 Seagate 1.5 TB in RAID 6, 4 Seagate 1 TB in RAID 5, 3 WD 2 TB in RAID 5, PC Power and cooling 1200 watt ps, Mountain Mods Ascension case, PC Power and Cooling 910 watt silencer (2nd installed), Plextor DVD, LG Bluray

4 out of 5 eggsJust Fine

Pros: I got it open box for about 250 and it was unmolestered ;)

Holds a lot of ram.

Runs well in windows 7 rc1 with zero driver installs so far and no updates.

With two L5410 quad xeons I get about the same heat waste as my old dual core proc that was only .6~ ghz faster with a slower fsb and mem. AKA -- its not hot in the room now and not noisy and my computer is faster, a good thing.

Cons: The board could use some more ports, such as usb and has no firewire ports, only headers(no big deal really).

Not a con on the board itself but I can tell you to go and get yourself a cpu cooler such as the dynatron h46g(x2) and that little plate will save you a lot of hassle fabricating a part that SHOULD come with the cpu or mobo. It snugs the cooler to the board and does NOT require making standoffs or other elaborate contraptions to attach the heat sink(you will need something, else if you have the time, a mill, a tap and die set, some calipers, a drill press, be my guest and make those plates or drill and tap some aluminum standoffs, not me, though i have all that the price is cheaper than my time). That fan is dead quiet when you set the bios correctly.

Other Thoughts: Why in the world doesn't either the mobo or cpu come with a full mounting solution? That's just flat out ignorant in my book. Are they attempting to help the job of installation tech retain its lifespan and thus increase revenues by offering some certification or what? Here's a car chassis and the road, if you can make it go its yours.....

5 out of 5 eggsNothing but the BEST!!

Pros: The is the most stable board I have ever used. It has a quiet mode setup in the BIOS that is truly quiet without sacrificing temperatures. The BIOS is very tweakable. I will be putting a water cooler on soon, but only because I have it. I purchased it for a TYAN board which needed it. I went through three TYAN boards before discovering this one. For some reason the TYAN boards do not seem to last. Thanks to NEWEGG reviewers, for giving this board such a high rating. It deserves it!! It is fast, stable, quiet and powerfull. Couldn't ask for more.

Cons: This board did not start when I recieved it. I did a cross ship with the mfg. at their advice. They said the first board had "issues" Newegg RMA'ed the first one no questions asked!! Newgg ROCKS!! After spending hours of frustrating time, I decided to send both boards back. I cheked out this site at the 11th hour and I found the answer to my problem. It is a power supply issue. With a Thermaltake W0R133RU 1200 watt P.S. ONLY the 8 pin 12 volt and 4 pin MOLEX connector can be attached NOT the 4 pin 12 volt connector. This is not the way the manual or Supermicro techs say it should work. I ended up keeping the cross ship as I had already sent the original back. Newegg made this expierence painless. Thanks Newegg!! If the power LED does not light their is a power supply issue. Try different combinations for your supply before returning anything.

Other Thoughts: 32 GB RAM, 2-73GB Seagate SAS HDD's, 1 TB Seagate SAS HDD, 1 SATA 500 GB HDD, ! SATA 320 GB HDD. 2 Visiontek 4870's. Liteon SATA DVD RW w/ litescribe. Philips DVD RW, LIAN-LI PC-P80 case, Thermaltake W0133RU 1200 watt P.S., Hauupage WINTVHVR1600 DUAL Tuner, Swiftech H20-220 APEX-GT (just the radiator) w/ EK-Supreme water blocks and Feser Coolant, Koolance flow monitor. HP 2475w monitor, 2-Dell 2209wa monitors on Ergotron Monitor wall mount.

5 out of 5 eggsVery fast

Pros: This really is a very nice board. It is not for those who haven't worked with more advanced server/workstation boards though. Mounting the processors requires you to put mounting pins underneath the board. The good side to that is that the heat sink and fan just screw right into place.
The processors I chose (Xeon E5410) run very cool in this board.

Cons: Size. Yeah this is a big board, but what do you expect? It was a bit of a tight fit for the case I chose, but once I got it in it was a dream. The location of the connectors could be better as it was hard to reach.

Other Thoughts: I put 32 gigs of kingston DDR2 FB 667 memory in here.... note that unless the processors run at 1600 fsb the default memory speed will be set to 667 even if you put 800 in there. You are better off investing the money elsewhere. Overall, this a solid board and Supermicro has a very good reputation for making very usable motherboards.

5 out of 5 eggsWhat a beast

Pros: Very fast and stable

Cons: None so far

Other Thoughts: It's big, but it's a server board so...... Ripped through an install of 2008 SBS and even with only 4 gigs of ram it is running great, ordering another 8 gigs next month.

4 out of 5 eggsVery solid workstation mobo - after solving power mystery

Pros: dual socket 771 supporting very fast or very cheap quad core CPUs, plus PCI-e 2, 6 USB, fast FSB. Rock solid so far, fast. Intel RAID and Vista 64 were very easy to install RAID 0 for OS and games very fast

Cons: no SLI (not a problem for me as single GTX280 enough), could use more USB headers, big problem was providing power. Board takes 3 plugs 24 pin ATX and 2 12V EPS (8 pin and 4 pin) - if you have a multi rail power supply (which you might expect using a board this capbable) you Better make sure all 3 plugs are fed from the same power rail. Board would not POST for 3 days of trouble shooting until I switched the 4 PIN EPS to the same rail as the other 2 (Corsair HX1000 PSU) This issue not mentioned anywhere in either company's docs - make sure you have a PSU wiring diagram

Other Thoughts: careful what HDDs you use for RAID array some of the more sophisticated HDDs (WD caviar black for example) are bad choices because the sophisticated fault detection built into drives can cause the drive to fall out of the RAID array by timing out as it runs internal fault correction - do your homework (I didn't)
