3 out of 5 eggsEverything works good, except HDMI connector

Pros: Like the layout
Plenty of SATA port, great for NAS
Ability to undervolt,

Cons: HDMI port is so lose, mean not a snug fit, like other motherboards or tv etc.

Other Thoughts: The main issue I have with this board is, the HDMI port being very lose, not a snug connection. I tried different cables, and it is little better in the case of some cable, but never the less small movement make it come out or signal loss.

I got creative and tied that for now, but it is really problematic.

But with undervolt, I was able to bring down my full load wattage with i5 3475S processor by full 15 watts which is considerable. Reduced power as well as temp.

If not for HDMI issue, it is 5 star..

5 out of 5 eggsLove these boards

Pros: -Asrock
-Easy to install, very simple board
-High quality product
-After about a week and a half of use, no problems whatsoever.
-Good for ANYTHING, gaming, home theater, etc.
Paired with a capable processor this board is unstoppable.

Cons: The USB 3.0 gave me some minor difficulties at first, but after I reinstalled the software I had no problems.

Other Thoughts: I needed to repair my parents PC, because a certain motherboard manufacturer whom I will not be buying from again was taking literally months to fix a bad motherboard that I had already had to RMA twice.

This board works great

5 out of 5 eggsLooking for a standard Micro ATX

Pros: Looking for a standard micro ATX with sata III and USB 3.0. This may be it since its sturdy and hasn't gone down in 2 months. If this doesn't work I'm going to resell intel because newegg, msi, and asrock will NEVER replace or refund with a new board if there is a problem. and you' ll have to pay extra to get it.

THere are no honest motherboard companies, but you can't live without them.

Cons: none yet. 2-3 months in..

5 out of 5 eggslovely mobo

Pros: what more can i say that this mobo rocks. asrock seem to have been doing really well. post boot 1st time no problem. runs my i5 3570k nicely, and my 1600 Mhz RAM like a dream. you have to overclock the RAM in bios though.

Cons: not really a con, no overclocking features.

3 out of 5 eggsDecent Board, but had to RMA

Pros: Decent mATX board for the price.
Supports PCI-e 3.0 and USB 3.0

Cons: The layout, particularly the arrangement of the PCI-e and PCI slots, is unusual. Doesn't allow for two double-deck graphics cards in a mATX cube because the second PCI-e slot is at the edge of the board.

Other Thoughts: My board's PCI-e 1 slot was not functional. My graphics card couldn't be detected except in the PCI-e 2 slot, but because of the layout of the board, this solution would not fit in my case.
Sent out an RMA request to Newegg today. Will probably seek out a board with a better layout of the PCI slots.

4 out of 5 eggsNot bad

Pros: Easy setup
Very configurable
Relatively inexpensive
24 hrs burn in with no bluescreens or restarts. Seems reliable.

Cons: Did not detect my DDR3-1600 ram as DDR3-1600 (detected as 1333). I know some ram manufacturers default the ram to slightly slower settings, but the motherboard does not even have the option to enable DDR3-1600 on my ram. I will be updating the BIOS asap to hopefully address the issue.

USB 3.0 Western Digital Passport 1TB would not work when plugged into USB 3.0 ports. USB 2.0 based WD Passport worked fine plugged into the USB 3.0 ports, and even the USB 3.0 drive worked when plugged into USB 2.0 ports. This *could* be the fault of my OS (Ubuntu 12.04) or the drive itself, so I did not deduct an egg.

Other Thoughts: Impossible to test if my ram is good at the advertised specs without my motherboard allowing me to set them to 1600 (since my other computers are DDR1 and DDR2 only).

5 out of 5 eggsASROCK B75M Mobo

Pros: 1) Modern features (UEFI BIOS, DDR3 1600, PCIe 3.0, Ivy Bridge support, SATA3, USB 3.0, GB LAN).
2) UEFI BIOS has lots of tweaking options.
3) All solid capacitors.
4) Socket 1155 with good placement so just about any cooling solution should fit.
5) VGA, DVI and HDMI out.
6) Support for Intel business features.
7) Legacy support (PS/2 ports, LPT1 and COM1 headers).

Cons: Tricky AHCI drive setup for older OS (see below)

Other Thoughts: There are 6 Intel SATA ports (5 SATA2 and 1 SATA3 port) and 2 Asrock SATA ports (both SATA3) on the MB. The SATA3 ports are between the ATX power connector and the fan header. The 2 next to the ATX power connector are the Asrock SATA3 ports. The 1 next to the fan header is the Intel SATA3 port. Keep this in mind if trying to load an older OS like WinXP with the SATA3 ports in AHCI mode which will require you to press F6 during OS setup and load the AHCI drivers from floppy (Intel's AHCI drivers for XP can be extracted from the included CD). There are no AHCI XP drivers included for the Asrock chipset - don't get burned like I did. If installing XP with the SATA ports in AHCI mode you MUST plug your HD into the Intel SATA3 port. If installing Vista/Win7 then you can use any SATA port you wish with AHCI. Also, both sets of ports are separately configurable - the 6 Intel SATA ports can be set to either AHCI or IDE mode and the 2 Asrock SATA ports can be set to either AHCI or IDE mode.

4 out of 5 eggshtpc/file system

Pros: -memory layout is far enough away for raised heatsinks and aftermarket coolers.
-Lots of sata slots

Cons: -PCIe & pci slots too close together. first pci slot is useless if you have a large video card. 2nd pci slot sits about a inch away from cooler of video card.
-No PCIe-1x slot
-only 3 fan headers
-No optical out

Other Thoughts: -B75 so no overclocking.
-Was able to dump in 2 video cards and a sound card but no TV tuner.
