**[OFFICIAL]** GIGABYTE Z77X Owners Club/Discussion/Info (All Model's Welcome)

[cowie]

I have a board that is messed up in its head...i get no power sometimes no lights when powered up at all....take pot off then power comes on puts a stock heatsink on no power agian reseat cpu no power at all....i used the board 10hours tops this should not happen i would think?
letting it sit without battery for a few i hope that helps the poor thing.

[dinos22]

i would rma it mate, thats isnt normal

[cowie]

You know me dino i kill even the best of mb's,funny thuo both my p67 ud7's have been under dice/ln2 over 100 times and not even a hicup from them.
I did just check it again still no power,at least gigabyte rma was very good with my b2 p67 board when i had to send that back.

*Just got back from microcenter with another ud5h board this one boots np
Is on sale for $190 there

**
This f5 bios likes to freeze up at bios spash screen even when pushed alittle on dice.
whats better then f5? or go back to f4?

[sin0822]

you have a UD5H and you are messing with BIOSes F5 and F4? they are pretty old, try out F7 or F8D, they are much more recent.

With Z77 just use GTL, boot up at like mid 4G and like 1.5v or whatever, then move it up in windows, it is much easier that way and less stress on the CPU, as you don't have to boot at 6ghz lol.

[cowie]

With bios i normally dont try to fix whats not broken since i only use this setup a few times a month at most.
i do use gtl also and getting this mb to get my 3750k to 5.5 with 1.56v but only dx9 benches.It did seem that the f5 was better for using less voltage.

thanks for all the info with this board sin.

[sin0822]

yea man no problem. There are actually benching BIOSes out there for the UD5H. You can PM Dino for it, or i think perhaps he gave them to stasio to put up at TT.

You do have dual BIOS, so you can take a chance and flash a new BIOS see how you like it.

BIOS F9D the most recent seems to be really pleasuring a lot of users, it also has CPU PLL Overvoltage added in there for users to disable if needed, otherwise it is engaged on enable if you OC.

I think a lot of guys like F8D for benching, so it is just a suggestion. The switch allows you to have one BIOS for normal use, and another for benching or testing, the vreg on these boards are excellent, but if you bench LN2 and you want stronger LLC ask dinos for the BIOS or it might be on TT.

2nd that F9d is working great for me.

@ Cowie

my 2c...... IMO the early BIOS's although also very good may well allow lower voltages (my 3570K also runs lower volts with the early BIOS's) however the newer ones if you feed them give outstanding results..... may be worth testing them.

[sin0822]

good to hear F9D is working well for you. Can you tell me do you need more or less vcore with F7 compared to F8?

[cab]

I just assembled a Z77X-UD5H

It came with F6 bios, I updated to F8, but it's still unfinished! WTF!
- memory timings and voltage ignored
- boot sequence ignored

So I loaded BIOS version F9d. Is this stuff official? I can now set memory timings & voltage but boot device sequence is still messed up.


Other than that, the hardware is very stable. PCH/Southbridge heatsink (next to the SATA ports) feels hot, 64C, is that normal?

Speedfan core temps will show correct values with offset +20.

Gonna post pics if you guys are nice.


Using ddr3 Samsung M379B5273DH0-YK0, this stuff is awseome if you can get it out of the package

memory timings and voltage ignored? How are the timings ignored? How are you inputting the values?

Did you load optimized defaults right after you flashed to F9D? All the BIOSes are official BIOSes, you cannot just go out and make a BIOS for another user. For your memory, F9D is the best BIOS for it, it is teh only BIOS where the board will set 1.35v at default.

How is your boot sequence ignored?

Yeah mobo set correct voltage by itself, running 1600 @ 8-8-8-22 1.35v

I would set memory timings, save & exit and no change, but with F9d it saves. Boot sequence is ignored, if you have a SATA3 plugged-in it boots first no matter what you've set in BIOS.

Great mobo, very stable, defect-free as far as I can tell. But the i5 3570k is disappointing.

Cant say I see this behavior, I am still on F5 (no need to upgrade). Try the "HDD BBS Priorities". The only unusual behavior I have seen on the UD5H are USB keyboard problems + mSATA drive(s) not being detected.

GigaBYTE support has explained I need to purchase 1 of 2 of these drives as they are the only ones confirmed to be working =

Dear customer,

We are unable to verify this unit as it maybe only for the Dell netbook
If you use an standard mSATA on the market on this board is it able to register it?

Dear vendor,

Please provide a list of compatible mSATA drives and/or a mSATA drive confirmed to be working in this configuration. Thanks

A few model of the Intel mSATA been tested on our boards.
311 "Larsen Creek" SLC / 20G / MSATA
310 "Soda Creek" MLC / 40G / MSATA

Why?

btw, sin0822 what's your vcore for 4.5Ghz here? http://forums.tweaktown.com/gigabyte...-analysis.html

[sin0822]

the 4.5ghz for testing? i just toss in 1.25v to be safe, it is easy testing and I don't stress the CPU much. Otherwise id use way below 1.25v. You should only need like 1.2v.

You talk about 2600K?

[C-N]

Hey Sin... you remember I said ages ago I could get my Samsung Green to boot 2600 single stick. Here's a pic I made whilst having another go. Obviously it needs to be slackened off to 32M or hold prime but still its very strange one stick boots so well yet I cant get 2 sticks to boot past 2380mhz. This was done in the DDR3_2 Slot

[sin0822]

you know what is odd, i actually got a boot with 2 stiks and teh 2400 divider, the board set some odd settings, but still fine, and i did 32m very easy.All i did was set everything on auto, set command rate to T2 and then voltage to 1.6v and booted straight, i checked the settings and GTL and wrote down the settings. However GTL doesn't give all the setting, and some of the 3rd timings where different than normal under gray, but gray isn't the right setting for the 2nd timings.Anyways if i input the timings from GTL, i can't post even normally, i think perhaps timings combos are the key. However i tried too and I can boot at 2666 with single stick in 1 or 2. I think it is perhaps a 3rd timing that needs to be in lin with a second timings, perhaps it is throwing things off, maybe the IMC gets way too stressed out with the auto timings set for this kit when you set some of the timings. What is odd tho if i try again i cannot get those same auto timings to occur.

when i get power back ill look into it more. Ima use your info try and see if i can get it to work on either board.

[C-N]

Yeah it would be nice to get at least 2400 running easy. I go through as many combo's of voltages & timings as I can think of every time a new BIOS comes out & so far haven’t come up with anything any better than my first go.

I didn’t check with GTL as I think it & ET6 need MDAC or something like that to run & I cut that out of the OS I was using.... :facepalm:

What we need is a nice open BIOS to have a little monkey around with all the mem timings going on in the background

Edit: I got GTL & ET6 running the problem was just that I had some required services... think dcom & Windows installer disabled

[cab]

I think Linux does not fully support the Z77 chipset yet. I'm getting intermittent hang/freeze in Linux but Windows is very stable. I've tried Ubuntu and Mint, any other experiences?

[Oliver]

THC and I got a try with the UD5 :-)

Gained in memory clocks (1446 > 1491) was on gd65 before.

CPU-Z says my Z77-UD5H board (bios F9e), 3570k CPU & Samsung 2x 4GB 30nm memory is running:
DDR3 @ 1.28 volts, 11-11-11-29 timings. CPU core voltage hovering around 0.90 volts at idle (1616 MHz.)
CPU-Z shows memory slots 1 & 3 as being occupied, but the UD5H printed owner's manual shows those same memory slots numbered as 4 & 3.
System cannot boot if memory slot 1 is occupied (the slot furthest away from the CPU).
Note: CPU-Z seems to call the memory slot closest to the CPU as "slot 1". The Gigabyte owner's manual calls the same slot as "slot 4".

[sin0822]

you are supposed to install in slots 1 and 2 as per the manual.

[vailr]

you are supposed to install in slots 1 and 2 as per the manual.

The owner's manual does not match what CPU-Z says, as far as memory slot numbering.
My guess: the Gigabyte owner's manual has it (the numbering) wrong, and CPU-Z has it correct.
That is: "slot 1" is now the slot CLOSEST to the CPU. Which is a change from previous motherboard memory slot numbering.
The previous Gigabyte boards had the slot FURTHEST from the CPU as "slot 1".
Installing memory in slots 4 & 3 (according to the UD5H owner's manual diagram) will result in CPU-Z showing slots 1 & 3 as being occupied, and that "Dual Channel memory" is enabled.
Owner's Manual numbering (going from furthest > nearest to the CPU): 1-3-2-4
CPU-Z numbering (going nearest > furthest from the CPU): 1-2-3-4
If you simply install 2 memory sticks and follow what the printed owner's manual says about memory slot numbering, the system will be unbootable.
Edit: CPU-Z version 1.61 x64.

[sin0822]

the manual has it right as you are supposed to install in slots numbered 1 and 2 first.

CPU-z is just a piece of software written by some dudes, it isn't some work of art.

Au contraire.
As stated previously: "If you simply install 2 memory sticks and follow what the printed owner's manual says about memory slot numbering, the system will be unbootable."
Therefore: the printed UD5H manual is WRONG. And: I'm not the only UD5H user noting the error.
