Gigabyte UD5 overclocking; strange voltages

[Bugenhagen]

Since I didn't see a generic UD5 OC thread, I thought I'd post my settings / problems here. I hope this is the right place.

Voltage issue: When I OC (18x200 right now, 3600MHz, RAM @ 1600 7/7/7/21) I noticed that everything worked fine as long as I kept voltages on AUTO. I managed to fix the CPU voltage to 1.35 in the BIOS (1.28 in CPUz under load) and everything still worked fine.
The deal where I couldn't change QPI voltage etc. still kind of bugged me though, me being the kind of person that wants to know how/why things work/fail to work.
When I finally installed EasyTune6 to get some details on voltages and whatnot, I saw (to my great surprise) that the BIOS on AUTO set my vDIMM to 1.79v (up from 1.5), and my QPI is now at 1.42(boot) to 1.52(target), which seems VERY high to me as well seeing as how everywhere I read a QPI of around 1.35 as max.
I quickly manually set my vDIMM back to 1.66, which seems to be PRIME stable, but QPI at 1.42v gives me a BSOD.

What should I do about these voltages?


(IOH core is set to 1.32v @ AUTO as well)

Yes thats true
For a neat overclock u have to set it manually
With auto under 200bclk the temps used to touch 100 allof the four cores
so i set it manually to all of them my temps now r under 90
Make sure u updated to the latest bios

I did update to the latest BIOS. I'm just wondering whether or not these voltages are strange, and what I should set them to. ATM I'm running QPI @ 1.50, but I fear this is a tad bit high...

Re: Gigabyte UD5 overclocking; strange voltages

Please give me your full settings you are using and I will advise. Yes, they are likely all a bit too high, some maybe way to high when left in Auto.

Please also link me to your ram or give me the model #

About QPI Voltage, 1.5 is likely way more then you need and a failure at 1.42 may have nothing to do with that actual setting. Less can be better then more for sure, your failure at lowering it may be due solely to other settings being to high or incorrect. I had been using 1.34-1.375 QPI/Vtt for several 3.8-4.2 setups (190-200 Blck) and found this past week that only going lower then that would allow those same setups to use 200-210 Blck range. So just keep in mind failure does not always mean that something needs more voltages

This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

Re: Gigabyte UD5 overclocking; strange voltages

Those settings don't work for me :( Don't even get a POST at your settings and at 18x instead of 20x it BSODs
