4 out of 5 eggsGood board, a little finicky

Pros: 6 Pcie slots
Easy BIOS setup
Works great with USB3 Risers

Cons: Seems to be pretty picky when it comes to pcie presence detection. Did not like my cut ribbon risers.
Had to RMA a board that let out the magic smoke on the FUSB1 MOV (nothing was even connected)

Other Thoughts: Needs to come with a push button mounted on board for a power switch.

5 out of 5 eggsgreat board for mining with 750 ti

Pros: Easy install and setup with Windows 8.1 Pro
Have 6 EVGA 750 Ti Cards running on it.

Cons: None that I have seen

Other Thoughts: This is a great Motherboard for mining. It was easy to setup and run. After you install cards, reboot and had no issues. I did not have to touch any BIOS settings.

1 out of 5 eggsNewegg has fallen behind their Competition

Pros: Good packaging

Cons: DOA- RMA

Other Thoughts: Had to RMA (hey- it happens). Will review product when I get one that works. However Neweggs RMA policy and system stinks. So far it has been 6 working days since the RMA approval and the replacement hasn't yet to ship. Going to end up being a couple weeks to RMA and get replacement. Not acceptable. I'm sure they want you to buy a new one and just get a credit for the bad one, but of course, that ties up your resources(money) and not theirs. Nah.... last time I go through this with Newegg (and I've been a solid customer of theirs since 2004). How do you spell Bezos? Last time I sent something back to them, they sent out the replacement before I had even sent the bad one back to them.... that's customer service IMHO.

4 out of 5 eggsAlmost a perfect buy

Pros: Low cost
6x PCI-E slots
Uses only one 4-pin auxiliary power connector (plus ATX of course)

Cons: I could not find an option in the BIOS to choose VGA preference. By that, I mean I am used to boards who lets you use onboard VGA even if there is a video card in one of the slots. This is wonderful for troubleshooting, but it would also clean up my setup.

Other Thoughts: I would have given this board 5 eggs if it weren't for not having an [obvious] option in the BIOS to force onboard VGA.

Biostar, could you please add this into a BIOS update? I would have just bought another if I knew it did this.

5 out of 5 eggsGreat Mining Boards

Pros: Simple setup.
Works well with passive extenders.
Has not failed me in the least!
8GB mem/32GB SSD/Celeron = extremely cheap backbone for your hash farm.

Cons: None. These boards have been rock solid for me.

Other Thoughts: I have 3 running 6 cards each (280x, 750Ti, 7870 - 6 of each) and these boards have been nothing but great.

1 out of 5 eggsWorst mistake ever

Pros: It has 5 PCI-E 1x slots. That's the only good thing about this board

Cons: This is the worst motherboard I've ever own. Nothing but problems with it. The cmos constantly fails (Nice CMOS FAIL message before POST) on boot up and resets everything, sometimes. That would be fine, if it would even detect the OS on USB more than half the time. Then, when it does work, half my GPUs aren't detected.

This board has been nothing but head aches. I plan on replacing it ASAP and throwing it in the trash. I will never buy another bioshit product again.

I usually don't bother leaving reviews, but I've been troubleshooting this system for the last 5 hours so I thought I try not to waste all of my time.

Do not buy this board. Get a proper mining board.

Other Thoughts: I cannot wait to go office space on this board.

Manufacturer Response:

Sorry to hear of your troubles. Highly recommend that you contact Biostar support for assistance, 626-581-1055 menu 2 or email The CMOS error you mention sound like CMOS has been reset due to possible failed overclocking or some sort of internal hardware/shorting issue and can be resolved by entering the bios and select the restore default settings in the exit menu of bios. For the GPU issue, depending on the video cards you have the chipset manufacturer has released drivers to solve multi GPU support, if you can contact we can provide link to the drivers for you.

5 out of 5 eggsGood mining board, solid!

Pros: Bought this board when the ASrock mining board was out of stock. I was a little worried, as I've never purchased a Biostar board (Usually stick with higher end brands).

I'm impressed, I paired it with a dual-core Pentium processor and 6x 79XX radeon cards and windows 7 64bit.

Runs solid , with no special configuration windows detected all 6 cards (though two with yellow errors). After adding the custom 13.21 driver (google search it), everything is solid!

Only issue I've noticed is the usb3 driver on biostar's site doesn't seem to want to install. I haven't spent to much time trying as Its not a big issue for now.

6- Pci-e slots

Cons: Now out of stock?

Other Thoughts: Running with 6x79xx series cards, two-1000 watt power supplies.

5 - 1x usb3 (powered) risers
1 - 16x ribbon (non powered) riser.

No dummy plugs.

5 out of 5 eggsSolid mining board

Pros: Price: when in stock these are actually pretty affordable.
Config: effortless, right out of the box.
Power: good power module with a nice heat sink.
Stable: flawless with 6 gpus and cheap powered risers.

Cons: No actual problems yet identified.

Audio upgrade probably not useful unless you like to rock out while you dig, or can rig up some sort of noise cancellation solution to drown out all your fans.

Other Thoughts: Owing that most users will not mount these into a chassis, mining boards like this should really be bundled with a small switch/light/speaker module that neatly interfaces with the header. No stars deducted.
