    Dont spend more than you have to on more expensive boards

    There is alot to talk about - this is where price meets performance o 8 SATA ports 4 SATA 3 and 4 SATA 2 ! o 8 USB 2 3.0 6 2.0 (remember your external hard drive really isnt going to be limited too much by 2.0 so dont sweat not having more than ... Read more

    Top Critical Review

    Decent, but had problems

    However, I got bizarre periodic lag spikes for some reason, and I couldn't for the life of me figure out why since no one else on my network was getting them. Eventually I replaced the motherboard and I've not had the same issue since. It's ... Read more

    5 out of 5 eggs Still running smooth after 2 years and 7 months

    Pros: Very nice for its price
    Usb 3.0 header
    z77 chipset decent for overclocking
    lots of usb ports

    Cons: The ethernet on the board just died after cutting in and out for the last couple months
    no sli support
    kinda odd width which makes it look odd (now I'm nitpicking)
    chipset will get hot with crazy overclocking past 4.4ish ghz

    Bottom Line: This board is old now and Newegg doesn't carry it but if you're here after finding one used on the internet its a great board
    that will hold out for a very long time, Ive been running it with a 3570k at 4 ghz since I got it.

    5 out of 5 eggs great performance. Lasted for years.

    Pros: Great performance. Board has everything you would need for a fast computer. Board has out performed my others for over 5 years.

    Cons: The USB 3.0 never did work. after all the driver updates etc I never got the speeds to work better than 2.0. It always says "this device could work faster" when plugged into the 3.0 port. Sound ports died after about 2 years.

    Bottom Line: larger CPU rads block pci 3.0 slot
    lower pci-e slot is blocked by sata cord connectors if in use. After 5 years of use [i updated this review] this board has proven the most durable and has always performed. The new z170 extreme4 and 6 are worthless in comparison. Great board. I bent a pin on it a few months ago and had to replace it but I wish I could have got it fixed to keep using it. They cost more used on auction sites than they did originally.

    2 out of 5 eggs Terrible Quality/Support

    Pros: -Cheap
    -Worked for a year

    Cons: -Didn't even 2 years

    Bottom Line: I bought and installed this mobo in August of 2011. It died last week, after giving me problems for the last few months before that.

    No big deal, you might say. The problem is, their RMA service takes forver, i'm on my second week of dealing with this, and thats with me paying for overnight shipping to their HQ. Now that they have my mobo, they wont even decide if they'll send me a replacement for another 5-7 business days. Thats alot of time i'll be without my desktop because of some shoddily made product.

    Manufacturer Responses:

    Dear Sean, Sorry to hear that the mainboard has malfunctioned under 2 years which’s due to nature of electronic product, it can happen. We always do our best to provide RMA service to customers. Please visit RMA policy at " " . If you have any technical issues or warranty questions please contact us at We will assist you shortly. Thank you ASRock SUPPORT Tech Support Email:

    5 out of 5 eggs Great Value Board

    Pros: Easy to install, easy to power up. Has all the slots needed for those of us that find 1 video card adequate. Stable. No hick-ups on the install. Picked up my SSD and HDD no problem. Easiest install ever. I love Asrock boards, I have tried several brands that I do not think I am allowed to name and Asrock has always delivered the performance and stability. I cannot understand why people have given this board less than 5 stars.

    Cons: I have large hands so a little more width wouldn't hurt.

    Bottom Line: In all honesty I doubt that the Gold caps add that much to the board. I think that one is more for show.

    4 out of 5 eggs Giving ASRock a try!

    Pros: I really like the BIOS screen and how easy it was to update! Has everything I need for a solid gaming build, nothing fancy.

    Cons: Board is "flimsy" compared to other manufacturers. and it doesn't come with a speaker dongle to plug into the mobo.

    The manual was could have done more with pictures instead of graphs.

    Bottom Line: Giving ASRock a shot for this years PC build, so far I'm impressed with the simple look and the ease of everything.

    5 out of 5 eggs Very good, exactly what I need

    Pros: This is exactly what I paid for. It is smaller than my old one, easier to figure out/wire and is all around great for gaming (and I mean hardcore gaming)

    Cons: Only downside would be that you can't put 2 graphics cards on PCI express 3.0 as there is only 1 slot
