Re: GIGABYTE Modified Bios

Hey guys, just got a new GB Z77 UD5H rev 1.1.

If its not too much trouble can someone recommend/advice which bios its better from experience? Especially interested in stability/overclocking. (aren't we all? )

I know its subjective to each one but I will get some info from each experience.

The F15r-mod5 or F16c-mod3?

Thanks in advance.

F16c mod3 is great

Re: GIGABYTE Modified Bios

Hi,

It is possible to have the F12U Bios modded of the GA-X79-UD3, with the latest Gbe and all last Rom integrated.

Thanks.

Ghostearth.

PS: It's better to use @Bios or Q-flash ?

Re: GIGABYTE Modified Bios

F16c mod3 is great

After a very traumatic experience with dozens and dozens of boot loops, I manage to boot into bios. I booted with the optimized defaults and I flashed the F16c-mod3 bios.
I restarted and all fine. I then power off the pc and voila! Boot loops are still here. It came back to bios after 4-6 reboots.

Will try F15r-mod5 but I doubt it's the bios. If must be a defective board. If someone has any experience with the very very persistent boots loops on the Z77-UD5H rev 1.1 please share your experience.

I would really prefer to avoid RMAing it if it can be fixed somehow.

Thanks guys. And I apologize for my damn bad luck.

P.S: As I mentioned this is a rev 1,1 board and it came with the F13 Bios.

Re: GIGABYTE Modified Bios

Koniakki,
I'm running F16c mod3 by Stasio, and it's running great.
I'm using the Intel GPU for graphics (haven't used external GPU).
Check my sig for details.

I suspect either your board, CPU or RAM is malfunctioning.

After Flashing your Bios always clear your cmos for 10 minutes. Battery out and jumper to 2&3 or if have a push button push it for ten minutes

Yeah, I know its not the bios from stasio. I was having even more problem with the boot loops with the stock firmware that came with the board.

Now I dont know if I will have the same results with the stock F16 but I just used the F16c-mod3 from stasio and actually helped VERY much with the boot loops. I can enter the bios after 4-6 loops.

Something is defective. Using internal GPU also btw. I tried all RAM slots with both sticks of my 16GB Kingston Predator and I get the boot loops every time.

Hmm I will try that too. But really keep my finger pressed for 10 minutes? No offense but it seems a bit excessive. Also the Z77-UD5H afaik have 3 buttons on the Mobo. Clear CMOS, Reset CMOS and the big Power button. Which one I have to keep pressed?

Outdated ROM's.......here is newer:

GA-X79-UD3 - F12u-mod

Will be useful,if you list your full spec.,overclock or not,debug led code with bootloop.

Re: GIGABYTE Modified Bios

Thanks stasio for the modded bios f12u, but i've downloaded your files and get a file named 2826, about 90 ko, So i've to put this files with the new bios on the USB key and run q-flash or leave this file.

Thank you very much Stasio. For the bios, your hard work and especially for helping a new member. Thank you.

The boots loops occured even with the reset and stock bios, with or without OC. If I power off the PC its takes from 5-20+ reboots to come back.

Also the debug codes I see when it boot loops is almost a zero on the debug led. I say almost because it looks like the below every time.



Now when it finally boots it starts with 15 code, then I think it shows 4F, then 72, I believe then 99 as far as I remember and now that it works it shows A0. I will take a video next time. I can replicate it since it happens every time.

I had a Z77-UD3H yesterday when I bought the UD5H. I just took it out carefully, replied the TIM and start it up and the boot loops began. I then disconnected everything(GPU, HDD's) and I left only the SSD/H100i/RAM connected.

Re: GIGABYTE Modified Bios

I suspect you have OCZ PSU.......any spare or borrow from friends (not OCZ),just to check.
The second thing,you can try increase Vtt in BIOS to 1.10-1.12V.

To be sure,unplug all unnecessary hardware......try to boot with 1 stick of RAM and use on board video (with just SSD).
All on stock voltage.

Uhh,I forget to delete 2826 file.....I'll reupload link,thanks.

Edit:
Reuploaded only with BIOS file.....

I know that this doesnt mean something didnt go wrong when I took out the UD3H and placed the UD5H in but as I said all my hardware was connected to the UD3H and everything was working perfectly. Not bsod, prime/ibt test and benchmarked to the limits.

I just took out the UD3H and place the UD5H in.

Tried both sticks on all 4 slots. One stick each time. I tried with as few things connected as possible. Will do a Memtest again. You never know.

I have a spare 460W coolermaster PSU. I will try when I get time. Also I still have my UD3H but I really don't wanna swap the CPU's again.

Also the weird thing is I just finished 2hours prime and LinX and I run valley and RE6 benchmarks at my bench clocks with my GTX 690.

I mean it seems when it boots it works like a charm as far I see. No BSOD's, no errors etc. All USB works etc.

I found some people with about the same boot loops like me but I just wanted to see if any members here experience it and if there is a solution or something. If its a bios problem I can wait. No problems.

But I think its defective. Anyway after I test it with different RAM/PSU and if it still boot loops I will RMA it if no solutions comes until then.

I really love this board tho.
