What ver.CPU-Z you have?
Try ET6 and what is in BIOS ("MIT" and "PC Healt Status")?.
Did you "Load Optimized Defaults" after flashing?

My Vcore is OK with any modded BIOS.

afaik CPU-Z does not read vcore of Giga mobo correctly it's actually showing the VTT aka VCCIO

Yes, I loaded the default value after flashing.
The ET6 reported the same value as shown in CPU-Z.

By the way, you add the voltage at vcore or dynamic vcore?

Voltage for Vcore.I didn't play with DVID.
Can you check in BIOS "MIT" and "PC Healt Status".

I think that mobo itself (hardware) don't have posibility to increase Vcore (GIGABYTE All Digital Power Engine).

Last,you can try to increase Vcore with ET6 or GIGABYTE TweakLauncher (but I doubt).

Yes, I think it is the hardware limitation.
I tried both vcore and DVID and it doesn't change the real voltage value.

I'm stuck at 4.3GHz then.

P/S By the way, just for your info, my PCIE1x slot is not usable with the modded bios.

So now,
you can flash back to original BIOS.

Must have at least Z77-D3H (Z77MX-D3H) , to change Vcore.

Yes, it seems Z77M-DSH doesn't have "Gigabyte 3D Power".
Bad Gigabyte.

I find "Intel system" is cracking down "overclocking at budget category".
My office PC, Nehalem/i3-540@4.6GHz is running well with Gigabyte H55M-SV.
Intel started "K" in Sandy Bridge.
Now with IB, the Z77 budget mATX looks like a joke now.

Time to grab the baby monster Asus Maximus V Gene. This one is confirmed can OC like flying

I don't want to spend money on expensive board. I use it for HTPC. It delivers more than enough power for my HTPC applications.

If I were to change the mobo, I'd rather sell my i5-3570K and get i7-3770K (heard it can run 4.8GHz at default voltage)

Asrock z77 extreme 4 doing very good. Nice looking also.

You using 1 right now? me also interested with the board.

Yes, very good board. Im not planning to OC much, but
stock setting my temperature is 68c with H100's fan @ 50% spin
OC to 4.2(First attempt straight away success) no need to tweak voltage(around 1.168v) and my temperature just 73c with h100's fan @ 50% spin only,

My room is so hot because sun direct from my window, imagine aircond room, i think my temperature 60c only (Too bad air cond spoiled)

wah i nid to get rid my mobo asap.
btw i read from vortez review saying the mobo is thinner than usual atx mobo. i think if im not mistaken 3cm thinner. i scared the mobo bent if i use big cooler.

Hi, i also got extreme 4. just set everything up today. but as my pc doesnt have a dvd drive, i have to download from the website.
I hope i didnt miss out any drivers, but device manager shows 2 unknown devices. could be the IGP/virtu thing?

anyway hope u can share your settings for oc.

Refer to page 13, post 259, i posted my screenshot regarding my OC result.
Hmm DVD drive is a hardware, not a software, what you mean can download from the website?
Not sure about the unknown devices, mine working fine.

Prime95 v27.7 Build 2

Windows 64-bit: ftp://mersenne.org/gimps/p95v277.win64.zip
Windows 32-bit: ftp://mersenne.org/gimps/p95v277.win32.zip

when i took the mobo out from the box, it looked a bit bent to me already. then when i installed the CM evo 212, it looked even more bent.
very scared,esp when plugging in the atx connector. that side totally flexes when i plug it in!!!

Maybe the postman bend it!
I understand about the atx connector, because no screws to secure there . Luckily mine is fine.

Sorry to interrupt here. For the OverClockers information, ASUS P8Z77-V and above all have VCore adjustment. At least from my own internal testing. Will try to find out the the lowest end, P8Z77-V LX has it or not once i got it here in office. Cheers.

I wrote to Gigabyte to ask about the availability of vcore setting on Z77M-D3H.

This is the reply from Gigabyte. Classic!
