hey guys,
I need some help with my motherboard z87x-udh4

I'd like to upgrade my bios from F4 version. Tha last version is the F9 but much people find problem with theis version calling it very "buggy"... :/

What do you suggest for me?

Another question: There's a problem with the flashing of the bios file. Motherboard lets me flash the bios only via efi flash. But I have no idea hoe to do this.

Thanks

Latest version is F10, I've been using it for ages without problems.

You can download one with updated OROM's here, post 3918 (the OROM's are a bit outdated now but still newer than in the original F10):
http://forums.tweaktown.com/gigabyte/48085-gigabyte-modified-bios-392.html

It's also possible to update them to the latest ones using this tool:
http://www.win-raid.com/t154f16-Tool-Guide-News-quot-UEFI-BIOS-Updater-quot-UBU.html


To update with EFI Flash you will need to create a DOS usb boot drive (use rufus):
https://rufus.akeo.ie/

then paste EFI Flash onto the drive and boot from it, Gigabyte should have EFI Flash instructions somewhere.

Can someone explain to me a setting for the f10b bios. I understand this bios is beta, but even for f9 I believe the bclk is not a static 100 mhz. It gets rounded. i have set my multiplier to 45x for my 4790k. However cpu-z and other monitoring programs report 4489.29 mhz bus speed 99.76. Dram isnt even my 1866, its reported at 1864. I think this has something to do with the rounded and the offset of bclk. Why is this the case and do others see this in f10b, and is this normal, or should I try and play with it to get it closer. I do know some rounding errors are normal and nothing is ever exact. i also set vcore to 1.2 but cpu-z shows 1.198. I just want to make sure this is normal. I ran prime 95 and realized the cores were not in sync and the tests did not finish in sync, but that could be because I had other applications open. One last thing about uncore. I read here that is I leave on auto which goes from 35-39, from what I read in this guide. At 45x for devils canyon, do I need to manually set uncore to 39 or 40, or is auto okay at this speed.

I think in all honesty mate 47 has a timing issue with its restart and THAT is what's confusing every over clocker out there.
You can really try really fricken hard and you can actually succeed with some real nice overclocks, BUT, they will fail in my OP.
and in my OP
is a timing issue.

Hi everyone, I was overclocking my newly acquired 4790k on a Z87X-OC Force, and found I was unable to achieve the following from post #1:

"However now that Haswell has a built in VRM there is almost little reason to use offset mode b/c if you enable C3 power state and EIST the CPU multiplier and voltage drop together even if you have set a manual voltage without offset."

I enabled all the power saving features, and put 1.290V for 48x, and while the multiplier dropped in Windows the voltage did not. I'm sorry if this has been asked before, just wanted to understand what the above statement meant.

I tried offset overclocking, but unfortunately there seems to be a +0.04V increase once the load is present (not present when I use manual voltages).

hio peeps,

i'm currently running this oc on my i4770k:

4.4ghz at 1.188 vid (1.200 vcore)
4.0ghz uncore at 1.050 vring
llc is set to turbo on my ga-z87x-ud3h
vrin is 1.800

i'm wondering what vin1 in occt/hwmonitor is. mine reads 2.052 - seems rather high when i compare to others.
i'm thinking it could have something to do with the temps i get when stress testing with occt 4.4.1 (avx checked off).

cores reach 79/80/82/78 after 15 min - i use a noctua nh-d14 cooler.

can somebody help me out?

cheers!

"However now that Haswell has a built in VRM there is almost little reason to use offset mode b/c if you enable C3 power state and EIST the CPU multiplier and voltage drop together even if you have set a manual voltage without offset."

I enabled all the power saving features, and put 1.290V for 48x, and while the multiplier dropped in Windows the voltage did not. I'm sorry if this has been asked before, just wanted to understand what the above statement meant.

I tried offset overclocking, but unfortunately there seems to be a +0.04V increase once the load is present (not present when I use manual voltages).
For the z97 mobos, i know the only way for voltages to drop is to use offset. Just adjust values accordingly to account for the extra 0.04v. Mine adds an extra 0.02v in offset mode.
