1 out of 5 eggsDon't bother - northbridge overheats

Pros: nicely featured board for a no-frills powerhouse system, that includes a legacy pci slot

Cons: I can't get the northbridge to stop overheating. The original heatsink was idling at 55-56 degrees C. Removing it and reapplying thermal paste did nothing. Replacing it with a beefier fan-and-heatsink cooler got it down to 53-54. Adding a larger second fan blowing at the cooler got it down to >idling< at 50. Anything too extensive and the system reboots.

I'm looking to replace this board entirely - it's a dud.

The manual is joke - it's actually just an installation manual. Bad english and it doesn't even cover every step of installation. Good luck figuring out what those warning beeps are.

5 out of 5 eggsnot a problem

Pros: fast,stable, no issues

Cons: don't like having to use and floppy to update the bios . even wall mart no longer carries them

Other Thoughts: the floppy disk i had were so old they would not format . i had to go from store to store with no luck finally buying a 50 pack online . as for this server board i had no other issues what so ever . runs Linux like a champ. even makes a fast hackintosh :)
love the fully Linux supported realtek sound and Intel nics . this is a good all around hardware supported motherboard no drivers needed and stable as a rock

5 out of 5 eggsC7X58 experience - Excellent

Pros: Installed initially with Crucial DDR3-1333 memory [3 stix currently] and i7-950.
After installing v2 BIOS, [9/2010] unit operates flawlessly.

Incidentally, the manual implies 1333 memory will not be used on CPUs with 4.8GT QPI. While it is true that it will be used at 1066 speed settings, 1333 memory has SPD profiles that the board takes advantage of. Hence, the 1333 is not "wasted", and I recommend it.

Cons: Unit shipped with BIOS 1.0a. This was sufficient to power up with 1 stick of memory reliably, and allow flashing to v2 BIOS. Other configurations were unreliable until it was flashed.

Until v2 was installed, the memory configuration information in the user guides was totally wrong. I advise anyone to upgrade to at least this BIOS revision.

Use only with 4-pin fans. Mixing leads to problems.

Be sure to buy 1.5volt memory.

ECC is only recognized with a XEON CPU, despite misleading claims on various internet sources. [not a fault of Supermicro]

Other Thoughts: Board requires both 4-pin, and 8-pin CPU power, despite what the manual claims. I suggest only Power Supplies with 24-pin, 4-pin, and 8-pin motherboard connectors be used with this board. I also recommend I2C enabled supplies. Apparently this spec is somewhat new, and not as easy to find as I originally thought.

I have not used SLI or Crossfire technology on this board, even though it is capable.

I have tested many boards with Hyperthreading, and this is the first one that I have been able to leave with HT enabled and actually benefits from using 8 threads on it's 4 cores. Bravo to intel for finally getting it right on the i7.

4 out of 5 eggsWorks Perfect (except RAID)

Pros: I got this board refurb for $140! So that is definitely reflected in my review. Everything worked and Win7 had all the drivers already on it. Works great!

Cons: I couldn't run an install off of a usb stick and have my primary hard disk be C:. This would have caused havoc running windows. This is also a con because I don't have a CD drive :p and I won't get one. (ended up borrowing a CD drive for the install)

One more thing, correct me if I am wrong (jwleaman at gmail dot com), RAID is only supported at the OS level! How can a board advertise RAID but only support it at the OS level? Pointless -- now I need a card. This is the sole reason for 4, not 5, eggs.

Other Thoughts: Another reviewer noted you need 24pin + 8pin + 4pin for power. This is not true. Read your manual! The 4pin is optional and is only required when you have cards pulling a lot of power; presumably, you would only need the 4 pin with a high end graphics card.

The board is particular, but I don't consider this a con. The only memory supported is strictly 1.5v. If you want high end graphics you may need 24 and 8 and 4 pin power connectors. Not good for overclocking. If I were to reply to some people's cons I would say "Working as expected."

5 out of 5 eggsWorks for me

Pros: Works great for me. Purchased to work as an ESXi 4 server. Only running three Windows servers on it but so far it's been great. The NICs were reconized which was one of the deciding points. Very fast.

Cons: None yet.

1 out of 5 eggsDon't buy this from Newegg

Pros: They make you fill out the pros, even if there aren't any. BTW Antonio in RMAs didn't help me at all, and Newegg is now giving horrible shopping experiences. You've been warned.

Cons: I bought another Supermicro Board from Newegg and it arrived DOA. So I returned it to newegg b/c I just bought another costlier one at a local brick and mortar store, since I needed a computer badly, and didn't want to wait on a replacement. Newegg initially told me the board posted to RMA and I'd get a refund or a replacement. Then I got a letter saying that there were bent pins and that they couldn't do an RMA. Neither myself nor any of my friends that I had trying to help me diagnose my computer noticed anything out of the ordinary. I know they claimed damage, and now that they've shipped the board back to me there is damage to the pins. I can't help but notice this is a board no longer stocked by newegg. My hypothesis is that when the RMA dept. realized it couldn't be resold or RMA'd easily for them they intentionally damaged it and sent it back to me to deal with. I can't prove it, but the pins are obviously bent now where they weren't before and I will never buy from NE!

Other Thoughts: We'll see if Newegg even lets this review through because they will pull reviews that criticize their service efforts.

3 out of 5 eggsNice and Cool

Pros: Nice Layout. All solid caps. TONS of USB ports.

Cons: No Overclock ability. Requires a 24 an 8 AND a 4 pin (P4) for power.

Other Thoughts: I purchased 6 of these for my lab. They all run cool. I would have loved to have bought through newegg but they DO NOT TAKE A PO! Their loss.

4 out of 5 eggs

Pros: Update

Cons: Update

Other Thoughts: UPDATE - The SM C7X58 MOBO seems to have issues with DDR3s that are rated above 1.5V. Found the MOBO to be completely stable with 3 CORSAIR 1.5V TR3X6G1333C7G DIMM chips - The 1.65V TR3X6G1866C9DF were NOT Stable as noted [BSOD] in the 1st Bank, but OK as Bank 2 addons for 12G in short term testing? [CORSAIR and SM noted the 1.65V DIMMs would work, but they must be to close to the edge at 1.5V, which is the only BIOS choice for this MOBO?]

4 out of 5 eggs

Pros: Seems to be well made and setup and intergrated into the NZXT case without issues.

Cons: Would NOT Boot with 3 2G-DDR3 sticks 1.65V that were OK per SM TS prior to purchase. Loaded new "B" BIOS to get to boot with the CORSAIR PC3 15000 Dom. 3-Chan DDR3 kit included with the MOBD. It was unstable with Win7 RC or Vista X64 [BSOD Stop Error 124 every 30 or less min.] SUPERMICRO noted the BD was NOT tested with 3-Chan DDR3 and to use singles. It did run w/o errors with only one DDR3 2G inst. MOBD NOT ready for primetime DDR3 3-ch with current BIOS.

Other Thoughts: Will only run 1600 with the extreme high cost $1k CPU, so the 1866 DDR3 were limited to 1300 and ran cool without the overhead fan using the i7 920 CPU.

3 out of 5 eggsSurprise!!!

Pros: Good Rep.

Cons: Board shorted out and started smoking in a little over a week when I powered it up. So far, second board is running good.
