Welcome to GIGABYTE Technical Support!

Can someone tell me the difference between the GA-Z77M-D3H rev. 1.0 and 1.1? Also, what is the difference between this board and the one with the "-MVP" suffix? Comparisons on the Gigabyte site do not seem to show any changes. Thx!

I am not a computer geek, so bear with me.

I have a custom built dual monitor, dual BIOS WINDOWS XP Home Edition SP 3 system that has worked great for several years. The builder is long gone.

A week or so ago, it suddenly would not boot, stalling before the RAM numbers scrolled on the boot up window. After multiple offs and ons, it finally booted with the dreaded "Main BIOS Range ...Error". I researched what this meant and downloaded the BIOS (8KNXP F5 Rev. 1.x, 04/30/2003) from Gigabyte, did Q-Flash for the Main BIOS Update and everything worked fine, with about three boots executing normally.

But, then, the same identical boot failure sequence started occurring, again. Now, I am at a complete loss for what to do. Folks, I need your help.

I would guess that either one or more pieces of RAM failed, or you have failed capacitors on the motherboard.
Use Memtest86+ to test the RAM (individually if you get errors).
Visually inspect the capacitors on the motherboard for failure (they are cylinders and should have flat shiny tops - not buldging or leaking fluid).

Hope this helps,

Mark

Hi

I have the above board and note that the non p version recently had a UEFI bios release in July
Can anyone from Gigabyte tell me if there will be a release for my board?

I found the marketing info on the link below which lists the GA-P67A-UD3P-B3 as supported?

GIGABYTE Motherboards Ready for Windows 8

Although there is a sort of disclaimer at the bottom of the article directing you to the specific board support page
(which of course shows that it does not have a UEFI bios release)

Many thanks in advance from the UK!

Stasio / Acebmxer,

I'm using a Gigabyte GA-Z77-UD5H motherboard (with BIOS F14 Modded by Acebmxer).
OS: Win7 Pro x64 with SP1 eng (legitimate copy)
RAM: 2x 4GB Kingston DDR3-1600 Mhz @ 9-9-9-29-1T @ 1.65V
CPU: Intel i5-3570K OC to 3.8GHz
OS drive: brand new Intel 520 120GB SSD, connected to the Intel SATA3 White port

Intel SATA ports set to RAID in BIOS.
Win7 was installed with Intel RST RAID driver v11.5.0.1207 (using Load driver prior to Win7 installation).
Intel RST application & SSD Toolbox installed in Win7.

Using CrystalDiskMark v3.0.1c x64, I'm only getting around 185MB/s sequential write. Reads are OK at around 500MB/s.

Also tried connecting the SSD to the Marvell SATA3 port, but speeds were a little lower, so I went back to the Intel SATA3 port.

Anyway, the 185MB/s sequential write seems a little slow, or is this normal? I was expecting it to surpass 500MB/s.
In ATTO, numbers are as expected.

Hi I have a GA-M720-US3 Board and for some unknown reason I can't get the single Lan to work and have to use a Lan card to access the internet, any ideas on this.
Also is a lan card as good as using onboard lan.

May I say now how much I like this motherboard. (thank you Gigabyte)

But so many questions...
1. Are saved BIOS profiles saved on to the active BIOS chip? (and therefore lost if BIOS upgraded?)
2. Gigabyte's Smart TPM saves very important TPM Keys to the BIOS. Are these also lost if the BIOS is upgraded?
3. It would be overwhelmingly useful to know what changes are actually implemented in a new BIOS revision. Clearly there is no sense upgrading if the change only affects some hardware that you don't own.
eg I'm using F8... Do I want F14?
Some BIOS settings are entirely without explanation (as far as I can tell), and are even tricky to make sense of with Google
e.g. CSM Stack
Why are the Marvell SATA3 connectors (set to AHCI) described as SCSI removable devices in W7 x64?

Perhaps enough questions for now...

Best wishes

Hi. In process of setting up a new custom built HTPC based on GA-X79-UD3 MOBO and I-3820 processor. (See system spec's below). Initial WIN764 OS on Crucial M4 128GB SSD install had majority of Gigabyte MOBO Disk software & utilities succcessfully running. However, upon reinstall (by original Gigabyte MOBO disk or Gigabyte website 107MB download, I find I cannot get the HD Audio icon to show. It appears the Realtek driver only pretends to install but no luck upon reboot. Have tried disable/uninstall of HD Audio Controller under both Sound & System in Device Manager prior to reinstall with no luck. Any suggestions to get HD Audio actually installed and working would be greatly appreciated.

I see that the G1 ASSASSIN 2 x79 mobo is nolonger windows 8 compatable thanks to killer gaming nic, theres no windows 8 driver for e2100 nic, gigabyte have took the logo away from the board in there list on the website, so i dont think that there will be any compatable driver anytime soon.

I have several GA-EP45-UD3P MB's that have a problem with SSD's that have a SandForce SATA III controller. The BIOS hangs on the port the SSD is connected to when in AHCI mode. It appears to work OK in IDE mode. I am currently using FFb BIOS version. Is it possible to find a custom BIOS that will support the SandForce III (2281) controller on this MB. I understand that I will not get SATA III performance but the SSD even in SATA II mode is a whole lot better than a standard HD. Help would be appreciated.

Second question, are the PCIe X1 slots on this MB version 2.0 or ?. The manual states the PCIe 16X and X8 are version 2.0 but does not mention the X1 slots.
