Ok I usually don't ask advice about a motherboard but dam this one has so many mixed reviews. I have some nailed down on as far as the hiccups go with the ram and some of the Crap software it has on the driver CD. I was wondering if I can get the opinion of the community about this board. I did already order it I am just wondering if it is going to be a headache or not. I don't overclock and depending on the BIO's is uptodate or not I might have to do a bio's flash. I ordered it on Newegg.com

I bought this MB with AMD 8120 CPU and 2x4 Corsair Vengeance Red 1866 Memory. The memory shows up as 1366 at post, but there is a memory clocking section in the bios which you can set up to 2000. Not sure if the memory is running at full speed, need to run some tests.

I wish that I could remember where I saw the review, but I recall that there was an issue with BIOS not allowing certain RAM settings when all four slots were in use. Essentially, you would have to overclock the base clock to get to optimal RAM settings in many cases. I COULD be wrong, but that is what I recall taking away from the review.

I know it's in a bit of a different price range (not vastly, but $50 on Newegg), but I just picked up a M5A99FX Pro R2.0 board from Asus and was so happy, I upgraded my second system to the same board immediately. That was from the M5A97 and M5A88-M, which are both fairly good boards. The main thing that impresses me is the level of control over *everything* within BIOS. There is less to gawk over if you aren't overclocking. Although, as simple and safe as it can be with the mobo, I wouldn't see any reason not to. I just posted a stable OC of 4ghz on my X4 965 without having to manually adjust anything. A conservative clock setting to me would have been just going from 3400mhz to 3800mhz.

So, long story short- I think the gigabyte has a very mixed bag of pros and cons from what I have picked up on, dependent on what speed memory you intend on using and what other components are in play. I just would suggest the Asus board with the same chipset based on my own positive experience.
