Re: Welcome to GIGABYTE Technical Support!

I have a Z68 UD5 with a 2500K, oced to 4.9. It seems that virtually all of the oc info out there refers to Asus boards. Is there somewhere on here where I can get Gigabyte oriented overclock info?

Yes!

Please see Miahallen's guides here in his sticky thread, you want the Sandy Bridge one

I have a Z68 UD5 with a 2500K. Is it necessary to reset the bios on the board after a few oc failures?

Re: Welcome to GIGABYTE Technical Support!

You can clear the CMOS and or load optimized defaults if you are having issues, sometimes that does help

Re: Welcome to GIGABYTE Technical Support!

Hi all there!! Well i would like to receive some help about my problem. I ll give you my info below!
Mobo z68xp ud4
i5 2500k
Ram Corsair xms3 1600 4gb
PSU corsair HX750
GPU Sapphire HD 6870
SSD Corsair Force GT 3 60GB

Last week my board died and i got it replaced with a new one today so i rebuilt my system and i was ready to boot.
When i pressed my power on i waited 4 sec for the splash screen but nothing happened and the pc rebooted(damn here we go with a bootloop i said) so i rebooted many times but nothing. I removed one ram stick and removed the GPU so i could use the embeded gpu but still nothing. Now it seems that it doesnt restarts(very fast reboot) at all but i see that my LCD monitor goes off and then goes in power saving mode so i suppose it is still bootlooping!!
I will remove the battery,the power cord of the psu and leave it for 5-6 hours an then i will try it again. Any suggestions??

Re: Welcome to GIGABYTE Technical Support!

Go ahead and clear the CMOS as you mentioned, that may fix it! Also connect a case speaker if you haven't already, that way you can hear error beeps if there are any.

You may not need to do it for a long time, but if a shorter period fails then yes try overnight while you sleep. To try it shorter, just unplug the PSU from the wall or motherboard, then remove the CMOS battery, then press and hold the case power on button for one minute. Then plug the PSU back in, put the battery back, and then see if it will start or not.

Hello,

I have a gigabyte z68ma-d2h-b3 and core i7 2600. I cannot get VT-d to work and it's driving me crazy. All the reseach I've done tells me that my cpu supports VT-d and some z68 boards do or don't. I have flashed my bios that does give me the option to turn on VT-d (ad2h3vtd.f8) but that still doesn't work. Must I buy another motherboard to get this to work? If so, which gigabyte board would work that has LGA 1155?

I have successfully installed ESXi 5 with no problems. But the feature I really need is for a virtual OS to have direct access to hardware (VT-d).

Many thanks

Re: Welcome to GIGABYTE Technical Support!

Do you have the latest BIOS installed?
Try to press Ctrl+F1 at main BIOS screen and see if you get more options in advanced chipset features

Thanks for your reply!

I have tried each version of bios on the gigabyte webpage for this board. Each of those do not have the VT-d option in the advanced settings after you push ctrl + F1. However, the bios version I'm running right now (i got from another discussion board, http://forums.tweaktown.com/gigabyte...518-print.html) does have that option, yet it doesn't seem to actually work.

Seems not to be the top of GB priorities so you'd have to nudge them about it.
Didi you contact their tech support?

Not yet. I was hoping to find a solution online. I'll try calling them.

Re: Welcome to GIGABYTE Technical Support!

There has been alot of disscussion about Gigabyte boards and installing/supporting ESXi/Vsphere. Most gigabyte boards do not support VT-D. I was able to contact gigabyte and they added VT-D support for the EX58-UD5/EX58-Extreme the next beta bios they released after adding VT-D they ended up taking VT-D support out.

Only solution is to contact gigabyte and ask for VT-D support. Maybe if enough people ask them they might end up supporting it. The thing with having VT-D support is the device that what to have access to needs to be supported by ESXi and have the drives built in.

VT-D support in BIOS ad2h3vtd.f8....is in**VGA Setting**(Disabled by default):

G41 Express Chipset - Lose Video Memory

Well...

I Have GA-G41M-ES2L v. 1.0

GMA X4500 have 512Mb Video Ram, with 1gb System RAM (maybe if i have a 512mb of RAM, video memory must be 256mb but i think GIGABYTE GMA X4500 is with 512mb)
i plug for better perfomance, one more memory 1Gb.
So i see the video memory from 512 double to 1gb (i don't know why double the size of video memory).
im experiment with pavp mode on bios, on 352, so decrease general the memory of the system both (RAM-Video Memory). with easytune5 i overclock the same as the bios (M.I.T). and freeze my pc, show me red lines reflexing, i turn it off and system turn all back to default (bios) pavp look normal on lite to 32mb, then open the program of graphics accelerator Intel, down is the report*...
as i see the video memory still down here at 814mb
But system RAM is Normal
I think with the (unsafe) shutdown, when i use pavp paranoid mode on 352mb and flash back to default, pavp think it is on 352mb but looks on 32mb on lite mode default, normal.
please anyone help me!
You know what to do.
thank you!

Hello,

The P67-UD4-B3 F8 bios seems to introduce the power cycling bug. It also introduced a feature for checksum checking of the backup bios which cannot be disabled.

Thanks,
