that it changed, we'll talk, but very few reviewers go into that much detail on low end boards. So unless you own both and can do that for me, I'll write it off as not knowing the already existing issue with all
Rev 3.0 Giga boards, including the 990FXA.
It's been discussed here a number of times before. I can't prove it changed because I don't have a rev. 3.0, but a lot of people have reported getting Giga 970A-UD3 3.0 boards with Nikos MOSFETs on them, instead of the superior NEC ones that are used on their 990 boards and the 1.x revisions of the 970A-UD3.
The bad BIOS was a problem on all of the boards (and I did know about that too), but unless the people who said they got Nikos MOSFETs on their boards didn't know what they were talking about, they did change something (or someone at the factory messed up big-time). As far as the BIOS goes, when my 970A-UD3 (rev. 1.2) arrived, it barely worked at stock with a Thuban or an 8350, and I had to contact Gigabyte, who suggested updating to their latest F8a beta BIOS. Problem solved. So it wasn't just the rev. 3.0 that apparently could have BIOS issues.
I have no reason to slam the product. All I'm doing is getting 4.84 GHz stable on a motherboard that I paid $75 to get. I paid as much for the CPU cooler as I did for the mobo. If the board has the right BIOS and doesn't have Nikos MOSFETs, it's a great product.
Fair enough then. That is something to keep in mind.
Anyway, The BIOS problems with the 3.0's UEFI arent that the bios itself sucks, it's the limitations and HPC. LLC was already cut back so the 970a couldn't fully compete with the 990fxa boards, but the 3.0s added some really stupid things, like "Turn off HPC to change multi then turn it back on to keep the settings". *shudders* Killed OC potential.
Also, your OC is the reason the 970A is the only 970 motherboard I recommend for OCing. Shame Giga decided to cripple it, but we've been telling people to stay away from 3.0 boards anyway.

Obviously it can't keep it cool when running stress tests or doing rendering/encoding (which I almost never do). It was below 62C for games but still couldn't get stable. I know too much voltage is bad... but I had tried every combination I could possibly think of first. Throwing voltage at it was the last ditch effort which of course failed.
Sometimes my system will lose video when gaming (and sometimes just stress testing only the cpu-nb oc) and restart ~15 seconds later as if something overheated. But as far as I can tell nothing over heated? I have temp sensors on the NB and VRM heatsink which usually during intense gaming (Crysis 2 Ultra 1080P DX11 high res textures) are both at 62C. My 955 at 4ghz had similar temps on these. There's also a temp sensor on the back of the CPU socket.
Maybe it's the power supply? But it never did this with my old setup (955 @ 4ghz and crossfire 5770's oc'ed) which should pull more wattage than this current setup considering 220W+ for the GPU's alone.
All I know is I've tried pushing each component individually: just memory, just cpu-nb, and just cpu. Memory won't do squat past ~1900mhz (yes I tried 1.65V on memory) no matter the timings, cpu-nb won't get stable at 2500mhz, and cpu won't go past 4.72ghz. While pushing these components individually I even tried upping voltages on things you normally wouldn't such as HT Link and NB.
Maybe this 8320 hates the Mushkin + Crucial memory combo? That's the one thing I haven't tried, running only 2 sticks of either and OC'in. It's true I don't need 16gb for gaming and general use, but every now and then I do need more than 8gb when working on music... I have plugins that eat RAM for breakfast.
It's rev. 1.1.
Alright, so a higher VID, but not so bad that it should be cutting you off... It would be something to keep in mind though, we have a few high-VID (1.4v) people in the thread who can't seem to pass 4.7. You may just simply have one of those chips. You probably don't, they're rare, but it's possible.
PSU: It's a single-rail. Amperage is high enough to deal with it. Shouldn't be a problem.
RAM: I would try each of your kits alone. The other possibility is that the IMC can't keep up with that much RAM. I have 32GB because VMs and RAMDisks are cool, but the price I pay is I can't go over 1600 on ram and It takes a larger effort than I put in to get the NB over 2400. Keep in mind, I've run my 2x2GB Kingston kit at 2133 9-9-9 (With my CPU at 5.2, NB/HT at 2600), so the amount of ram can make a big difference. Running two different kits isn't really recommended for overclocking them either. Just because the timings are the same doesn't mean their sub-timings and overclock potential are the same. So yes, I would try with just one of the kits for that.
