But,if i set cpu voltage to ''normal'',that can make my I5 4670K @4,2 ghz overclock idle to 0,75 v,right? That can be to lower for 4,2 ghz,i guess? Now i have manually dialed in 1,13v for 4,2 ghz ,turbo auto and EIST/C-States disabled. I gotta tweak some offset further or static 1,13vcore is OK-ish for daily-use (i have very good temps with NOCTUA NH-D14)?... I know this is not the right thread to get advices for overclocking,but please let me know some things about that
Thank you!
Any whisper for a new official bios for GIGABYTE Z87X-UD4H v1.0? I'm with F8b right now,it is a good release,pretty stable,BUT it lacks three things: adaptive voltage,BCLK 100 and PCI-E Spread Spectrum ''disabled'' option (why Gigabyte insist to keep this ''enabled'' whithout giving the possibility to disable in the bios,is a mistery to me...). I know that is a new beta bios for my mobo (like F8c,i think),but i wait for an final F9.
Stasio,can you feedback to Gigabyte about those 3 missing features to be implemented in a future release,please? Thanks!
I oc-ed my system to 4ghz on air at first(cm 212 evo). Never troubled with the spread spectrum. Someone has a brief guide on Overclocking with the z87x. It's quite helpful. I used Cpu-z vers.1.63 to help with the base clock( 100mhz). Setting Manual. BCLK shouldn't be too much of an issue. Didn't like the vcore temps. Got a corsair water cooled system , Oc-ed to about 4.4ghz. Vcore could be 1.20v plus at that point, vrin 1.8+. You have a good cooling system so you should be able to get good stable temps at higher clocks. Did you prime test to see how stable your system is? My Bios was F6. Anyway with a good chip you can definitley get better results at high clocks with lower vcore. I'm currently back at stock clocks with bios f7 fixing hardware compatibility issues. I only worry about Vcore values near 1.4v.
Edit: Ah, nevermind me, I see Stasio already gave you links and info!

*Once again, uncore on "Auto" is allowed to increase automatically instead of staying fixed as in F8e. IMO staying fixed would the right direction.....but I guess that's debatable....
*Missing & greyed out items in Advanced Voltage settings, still.
*Channel A RAM timings still not appearing on main page of UEFI BIOS since F7.
But (in my opinion) allowing uncore to change by itself is not optimal. As I said, BIOS F8e "Auto" setting kept the uncore locked on 35 for my 4770K.
I forgot to check if Vring is still automatically increasing when set to "Auto" & clock is increased. In prior versions I've had Vring jump to 1.3v with a OC of 4.6. If set manually then it does not stray so far.
I wish so much that the good folks at Gigabyte that are responsible for BIOS would pay attention to what they change....when something good happens in one version, then disappears with the next, you have to wonder what is going on. Also I do not understand why Gigabyte is so slow to upgrade firmware in BIOS...fortunately we have some great folks here that can do that for us.
Just IMHO.

I'm still using bios F8e on the Z87X-UD5H, and there are the following issues:
- System suddenly shuts off after 60 seconds of inactivity at the password screen of Bitlocker. I have asked about this on other fora, but no-one seemed to know the cause. This problem happens even with a clean installation of Windows 8.1 with no 3rd-party software, and with different psu's and hdd's, and with no external devices connected except for mouse and keyboard.
- Changing fan settings in the bios or changing from fast to ultra fast boot seems to corrupt the boot sector, since when I change those, hibernation doesn't work properly any more: the system doesn't resume from hibernation.
- It frequently occurs that the cpu fan speed has changed from its normal "silent" speed of ~1200 rpm to a constant ~1800 rpm after resumption from hibernation.
- The fan connected to sys_fan 1, which is an identical model to the fan connected to sys_fan 3, doesn't spin up as easily as sys_fan 3. It frequently occurs that sys_fan 3 spins up normally, while sys_fan 1 stays stuck. Both fans are Noctua NF-A14 PWM fans. I have applied the exact same settings to both the fans in the bios ("Normal").

Does BIOS F7 work well for you? It works pretty good for me, but I like the way the uncore is treated in F8e so I will stick with it for now, or actually virtualfred's F8e mod 2.
I'm on Windows 7 Pro 64 and I don't think I will be in any hurry to "upgrade" to Windows 8.
