Well never say never when it comes to motherboards and cpu's, I guess. I tested both of my UD5H boards thoroughly when I first overclocked them, and in no way did lowering CPU PLL help with temps. I'm glad to see that it does help someone, though. I have one 3770K that runs so hot at x45 it's unreal, even under water and lapped, and absolutely nothing helps the temps with that one. I 'm talking about low 90's running Prime 95 with custom water cooling! At x44 it's not so hot, and really it's only when stress testing that the temps show their ugly head, but still....
My other 3770K would function OK at lower CPU PLL up to about x45, but above that it seriously impeded overclocking stability. So maybe it falls more on the cpu side than the board side. These darn 3770K's just seem to have so much variability between them I can't believe it.

You need to enable CPU EIST. That's the cpu stepping (downclocking) at idle by lowering the multiplier. Sleep states (c states) don't control that function.

Im trying to hit a stable 4.5ghz on a 2600k.
so far i have it at 1.3v and all the c states enabled because I want my multipliers/vcore to drop when idle. I ran the intel burn test and i would get bsod... and some people told me to change the llc. I also dont see my multipliers dropping when my comp is idle as well =/.
also anyone know the difference from the newer ud5h board from the old one?

there is no different in CPU oc, set LLC to turbo.

If you want the multiplier to drop you need to enable EIST like already mentioned. If you want vcore to drop as well then you need to use DVID offset, by setting vcore to normal and then setting an offset voltage. If you get a BSOD then you need more voltage you can try LLC extreme too. ALso set phase mode to extreme perf.

Hello Everyone.

Just brought the UD5H and seem to be having some problems (probably caused be me being a noob).

1st. When ever I change anything in the bios and save and boot, windows comes up and says MBR is missing press 'ctrl+alt+delete ' to restart. The only way then that i can boot the machine is to clear the CMOS.
2nd 2 off my HDD (SATA) drives do not show up on 'my computer. These are only storage drives but I do need to access them.
3rd The little OCZ mSATA drive that i got for using RST doesnot show up in my computer.
4th I Cannot get RST to work at all every time I have tried it I have had to reinstall Windows as NTLDR error comes up.
5th Computer takes quite a long time to boot

I've done a BIOS update to Z77X-UD5H F14.

Other than the above the machine is up and running now but i would like to make full use of all the features available if possible. I'm hoping that i'm just being really stupid and these problems are easy to fix.

Oh by the way I'm not that brilliant on BIOS speak yet so please be gentle smile.gif

I am a bit stressed though cause when i opened the amazon cartoon i found out that the motherboard box wasn't nylon wrapped nor did it have a seal of any kind (i.e stickers), is it normal? I checked the CPU pins and they seemed ok to me.
has anybody used the HP_PWR connector to light up Raystorm? That connector seems proprietary.
It seems to be a clever feature but the documentation is poor not to mention that is easier to see an oompa loompa than a connector of that shape.
And a last one, does anyone has Corsair Dominator Platinum 1866MHz . Its not in the QVL and they have told me horror stories about compatibility issues, so am a bit sceptic about proceeding to buy them (gaming PC).
Sorry for the question attack and excuse my ignorance smile.gif

i have been using gigabyte products for a long time and none of them had a sealed box, mobos and gpus

TLDR version: setting UD5H with 2500k to 1.35vcore in BIOS (F14) gets me 1.5v actual vcore instead of 1.35v

Ok people, there are MAJOR problems with the F14 UD5H BIOS.

I flashed to F14 a week or two ago but hadn't really sat down with the BIOS and tested to make sure everything was working properly until now. When I first got the UD5H + 2500k, I tested to find the highest, safe, conservative overclock for the 2500k CPU and it came out to 4.5ghz w/ 1.35vcore.

I had been running the CPU at 4ghz since I didn't really need the extra power but today I decided to crank it back up to 4.5 ghz for the first time with the F14 BIOS. After raising the clock back to 4.5ghz and setting vcore to 1.35v, I started to run Intel burn test just to make sure everything was good and I got some HORRIBLE temps coming back:



I couldn't figure out what was going on because my usual temps at 4.5ghz were in the low 70's then I open CPU-Z and it says my vcore is running at 1.5v, even though I only set it to 1.35v in BIOS. As soon as I notice the vcore and temps, it's just getting done with 2 runs of IBT and I immediately go to shut it down. Right then, I hear a snap/pop rice crispy sound come from my PC. The last time I heard a sound like that was right before I watched an ASRock board catch on fire.

This makes me really mad that through no fault of my own, I have probably degraded/damaged the hell out of my CPU and maybe even damaged the motherboard or both at the same time.

Just so you know this isn't a CPUZ or temperature readout error, here's what my PC looks like running 4ghz with 1.3v on F14 BIOS:



The only overclock related settings I had changed in BIOS for both pictures are the following settings:

Vcore: 1.35vcore for 4.5ghz and 1.3vcore for 4ghz
PWM Phase control: eXm Perf
LLC: High
All other voltages on "Normal", not "Auto"
Memory: 1600mhz, 7-8-7-24 @ 1.45v

First make sure you are populating the SATA III ports (white) first with your boot drive, secondary, etc and not the Marvell (gray), starting with SATA3_0 for boot drive.
Check and make sure you have the proper boot order set up in the BIOS. Save and Reboot back to BIOS and recheck. Then depending on your setup, you may have to select "windows boot manager" as first boot option.

I used to run it at 1.36v for the same oc, when I had a 2600k, so be sure to bump the voltage a bit till you get no bsods.
Then if you get errors while doing prime95 blend (custom, 90% ram size allocated), set LLC to turbo.
Up your vcore slowly, in 0,005v increments till the workers keep going on and you don't get any errors or bsods.
Also, after your system is apparently prime stable for 12hs, the last thing to check is the Event viewer log for WHEA errors.
Start menu_type event viewer_Windows logs_System logs.
If you see WHEA errors you need to either bump vcore two more notches or perhaps bump the imc voltage a tiny bit. (also enable pll overvoltage and set pll voltage to auto)
EDIT: If you're using offset getting a stable oc can be harder. Keep in mind that having a constant clock or vcore doesn't really harm the cpu. What harms it more is running high amperage AND vcore through it, which doesn't happen when idle. If you have a constant voltage but the current is less, the energy amount is less, and so is the heat.
So no worries there! You just get to save $5 on a yearly basis lol

thank you guys im going to set the Vcore llc to turbo and enable cpu eist. also do i have to set the phase mode to extreme or should i just leave it as auto?

Hey can you try this: First load optimized defaults. Then clear the CMOS, like really clear it. Take out the battery, disconnect the PSU, and then hit the button. Then load back up and load optimized defaults. Then see if it does that again. Also did you leave the board on auto vcore?
