Ok, So I got this thing thinking it would be nice for overclocking. I have overclocked a few systems but I am a novice.
Let us discuss the board.
Pros,
Price dang that is a good price and if you're just buying an X370 for SLI go for it.
Looks, Lights are nice and the system will glow whatever color I want. Nice
Fan controls. Ok, I had a way older board without a lot of onboard stuff. The Fan program from Gigabyte is awesome. Nice control plenty of fan and pump headers just an overall plus
Can we say M.2 Love it
Cons
OMG the BIOS, specifically voltage control. I can set my voltage just fine for memory. If I want 1.35 just type it in and 1.35 it is. CPU voltage Nope. We have three different Dynamic voltages. What, I want to set my CPU voltage and do a little overclock. So I can bump the Dynamic Voltage but that does not move my CPU voltage unless it loads up. Which seems to make it very unstable on anything but base clocks. Can't adjust lane voltage either. I must do some PCIE GEN 3 stuff to make it increase that voltage??? What.
Anyway, not happy I purchased this after looking on Gigabytes website. Wow, a overclockers walk through on my board's specific page telling me exactly how to do it. Oh, our bad that is a guide but that BIOS is a completely different board so yeah you can't do it like that.

I am a little angry about this. I feel Gigabyte led me astray. Looks like I get to put this board on eBay and buy a real one.

I'm in the same boat. Just put my system together last night. I haven't dabbled in overclocking much either but I do have an idea. Would the AMD Ryzen Master utility work to get around the issue? I believe you can adjust voltage within Windows on the fly. The only catch is Windows High Precision Event Timer (HPET) must remain enabled as the Master utility program requires this to function properly. I found that out from the article below. I'm currently messing with memory issues with some 3200 Gskill RGB sticks. I knew going into this that it'd fight me on it. I just hope I can stabilize it like others have. Really hope this works for ya so you don't have to mess with ebay ventures. What do ya think?

Same here, I got this board as a replacement for my dead msi carbon. Everything is working fine so I decided to try some overclocking and noticed I have no vcore settings? I turned off cool and quiet and the auto OC stuff. Then set the dynamic vcore voltage up a bit and noticed it does change the vcore. I bumped it up to 1.28 and had my 1700 at 3.7ghz. I have no idea why we don't have all the normal voltage settings on this board? Everything else seems to function fine. I was able to get my g skill trident to 2933 with the xmp profile. Is there some hidden setting to get access to everything on this board? or do we just need to wait for a bios update?

I have sent a nice ass chewing email about miss representing the ability of the product to Gigabyte. It is total crap as the overclocker guide on the actual board page shows we can adjust these settings. It is total bait and switch.

gigabyte use off set.
like this for 1.5vcore
I use way less for 1.32 myself
4 days now and works without a hitch.

I see, my vcore in windows is just 1.28! I would be a bit worried if i had to bump it up that much to get 3.7. It still feels a bit odd though not having all of the individual voltage settings like I had with my msi carbon board. Thanks for the info though! this means I should be able to oc a bit more with out a problem. My goal is to get to 3.8-3.9ghz.

I've done 3.8, 3.9, 3.95 and now 4.0Ghz with Gaming 3...

Though I did need excessive voltage for anything over 3.8Ghz. Anything above 3.9Ghz is risky. You risk going above recommended voltages and/or overheating/kill your VRM.

I just ordered this board and after reading about the VCORE issue, I called Gigabyte. After telling the rep the situation that the OP posted, he tried doing it himself and couldn't. After giving him my contact information, he said that he will let the BIOS team know about this and hopefully in a future BIOS update we will be able to manually set the VCORE for the CPU.

Gigabyte only uses offset on a few boards. The others you type in the voltage as normal. This offset stuff is limited to the K5 and a few others. The problem is the website gives you an actual link to a book on how to overclock it and guess what it is type in the voltage not the dynamic crap we have.
See the link below directly from the Gigabyte x370 Gaming K5 page.

The K5 is a terrible board for the price. It's about $170. I'm of the opinion it is at best a $130-140 board in terms of features : the value adds over the B350 Gaming 3 are minimal (SLI, BCLK, Sata express , Intel LAN , USB 3.1 Type C, LEDs at memory).

That's what the X370 Gaming 5 , ASUS X370 Prime Pro , and the MSI X370 Pro Carbon go for right now.

The Gigabyte Am4 overclocking guide uses their flagship $210 Gigabyte X370 Gaming K7.

1.80 on Dynamic VCOR gives me 1.41 volts. It holds 3.9 stable in AIda64 with a max temp during the stress test of 68C. This temp doesn't seem bad with my old corsair H55 AIO. I might be able to go higher if I can figure out what the hell all the other Dynamic crap is.

The problem might be that if you do not use the BIOS offset you might not boot into some higher overclocks. Though I've rarely seen that be a problem. You can combine bios offset and Ryzen Master for some higher voltages than BIOS allows alone.

For example max offset is +0.300V in bios. So if your base VCore is 1.18750 as mine 1700 has you can not get more than 1.488V through bios but adding Ryzen Master I can change the base Vcore higher and get more.

Right now I use +0.300V offset and have Ryzen Master set for 1.21250V and get a stable 1.500V

Mine 1700 needs that 1.500V to be somewhat stable @4.0Ghz. (everyday usage) passes 1hour Realbench stress test.

Mine will do 3.95Ghz with +0.300 offset only and pass IBT AVX but I needed 1 more click on the volts to be Prime95 custom blend stable. Bios could not do it alone.

Max voltage recommended is not more than 1.450V, or 1.425V for short periods or 1.350V 24/7 according to AMD (various posts and articles)

So I'm taking a risk to reach 4.0Ghz on my chip.

I have just gotten my 1700 / Gaming K5 build running, and i'm quite happy with the motherboard. My current setup is :-

  • 1700 @ stock (under volt using the offset voltag)
  • 16GB DDR4-3200 CL16 (Hynix) modules running at 2666mhz (XMP + 26.66 RAM multi)
  • R9 290 4GB

The install and setup went very smooth, put the build together and it all booted 1st time (with ram at 2100mhz default) to both windows and Linux fine. CPU auto voltage was also very good and kept the CPU running cool on the stock wraith cooler. I also haven't had any of these soft brick issues other have had with gigabyte boards.

Some other notes on this motherboard :-

  • At the moment its limited to setting VCORE voltage by offset (i'm guessing that will change in the next load of bios updates)
  • 2666mhz is the maximum it will do with hynix modules on the F2 BIOS (iv tried 2933 SoC @ 1.1-1.2v , DRAM @ 1.4v and 16/18/18/38 with no luck just reboots at POST)
  • Looks amazing, the neutral colours really do go well with anything (RGB is a plus but i'm not a huge fan)
  • Works 100% with current Arch Linux live USB
  • Audio jacks seem to be pretty interference free

Ummm.

Just realized this board has no ******* power switch.

God damn it Gigabyte, why you gotta do this to me.

Am I blind?

If it's returnable I would return it.

The power switch is the least of your worries if you are trying to run a 6 or 8 core on it overclocked.

You can wire up a power switch like on a case. (https://www.newegg.com/Product/Product.aspx?Item=9SIABR04YT7706)

Is it really that bad? I noticed some folks on Youtube had good results with it

It's definitely worse than the ASUS B350 STRIX / B350 Plus (which have 4C09 rather than 4C10 mosfets for the high side , so slightly better) unless you tune BCLK.

It's a $90 equivalent board with some lights + Intel LAN + BCLK. There's some $100ish boards with ALC1220.

AFAIK the lower tier Gigabyte boards don't allow fixed voltage OCs either for stability testing required to see what voltage is needed for each clockspeed. See the above poster's comment.

The Gaming 5 (not K5) is a $140-160 equivalent board with way better mosfets (~$20 worth) + some lights + Debug code LED + power/reset , Dual Audio codecs, and no BCLK. Oh and a useless Killer Ethernet (IMO) in addition to its Intel LAN.

Guys, so I just installed a Ryzen 1700 and Corsair Vengeance RGB on this board.

I'm getting lockups at stock settings.

Installed latest drivers and BIO (F3).

Anyone face similar issues?

There's many variants of Vengeance RGB. If you're trying to go more than 2666MHz you likely need above 1.35V DRAM voltage and 1.05 - 1.1V SOC
Because they have LEDs you likely have to use more voltage than normal.

2666 CL16
2666 CL15
3000 CL15
3200 CL16
3333 CL16
3466 CL16
3600 CL18 ... likely Samsung B-die
4266 CL 19 ... likely Samsung B-die
