Meanwhile, the integrated voltage regulator targets ~0.02v higher than you set in bios, but if you set 1.35 bios you'll never see more than ~1.37 from multimeter, with very slight variance (because ivr is pretty good at what it does, way better than say z77 mobo voltage regulation by design)

Thanks for the help. I need to upgrade cooling too.

So uh guys, how do i flash f9?

q-flash says it's out of date, @bios too

working on it~ http://forums.tweaktown.com/gigabyte/28441-gigabyte-latest-beta-bios-903.html

Messed around for half an hour, still can't flash, not sure what to do now


I got it, deleted my @bios files and installed it using the download from asian server on giga site, that worked

Use fixed Voltage.


Okay, so you cannot turn it off in a gigabyte Z87?


Conversations with Gigabyte Tech Support occur with latencies of 1+ days. You get the feeling you are dealing with Taiwanese people. Here was the conversation:

Question : I am overclocking my i7 4770 in BIOS. Currently, I set Vcore = Normal +0.222 Volts Offset Voltage. Does this setting provide "Adaptive Voltage," as mentioned by Intel? Or can Adaptive Voltage be set another way? Or is it unavailable?

Thank you.

 

Answer : Dear Customer,

CPU Vcore offset option provides “Adaptive Voltage” as mentioned by Intel.

 

So: I asked the inverse question from yours: how can I get Adaptive Voltage because there seemed to be no way to turn it on.

 

When I did my own OC'ing, I discovered that when I used Offset Voltage, the Voltage would rise beyond what I had set. The OC in my sig, for example, was an offset -- the max offset for this board. If you look at my 5GHz link, the Vcore is 1.512v, which is more than I set it for. After discussing Adaptive Voltage on the OC thread, we concluded that the only way to escape Adaptive Voltage was to set a fixed Voltage.

 

And again, since the Voltage VRM's on a 4770k are on-die, it appears that Adaptive Voltage is part of the chip, not the motherboard.

Thanks, I guess that means that the cooling solution,it's be very strong. Maybe that will be fixed in the upcoming refreshed CPUs ?

It seems to have helped me @4.7, i ran some settings with low volts that were just crashing in encoder within like 10-20 seconds before and went 4 mins straight first try. Seems like i can make real shots at stability in significant workloads now

Right. Until Gigabyte releases an updated Qflash, the newest BIOS need the latest version of @BIOS. That's OK I guess but I was a little put off that I had to install the App center. :shrug:

I'm running a modded version of F9 (latest ROMs/micro code, etc) on my UD5H @ 4.7 GHz and it seems to be OK.

Same here:
App Center
@Bios - Update from File to F9 Bios

Afterwards quicky uninstalled App Cnter + @ Bios biggrin.gif

Why uninstall the App  Center? Something wrong with it?

Probably nothing wrong with App Center I just dont like unnecessary (In my mind) Software on my PC.
