Somehow your BCLK running in "Fail-Save Defaults" so try clear CMOS, press F7 and load "Optimized Defaults" + F10 "Save & Exit".

My Fail-Save Default => BCLK same as your:



Edit:
If above didn't solve your BCLK value,
try to replace CPU and check if any socket pin bent.

Thank you, I reset CMOS using the mobo switch but BCLK is still 99.79. The hardware is very stable in Windows & Linux, it doesn't hang or BSOD, and it can run prime95 forever @4.0 GHz with stock voltage. Like I posted above, if I set BCLK to 100.01 the numbers look ok but the PCI-E card in the last slot is no longer detected, maybe NO cards would work! Any other ideas what caused this?

I said after clear CMOS, press F7 and load "Optimized Defaults" + F10 "Save & Exit"..

bckl
I have same issue the bckl drops to 60.4, 70.6, 91.1 (F12 Bios) This happens when C3 C6 is disabled NOT when its on AUTO.

Must be bicycle.

Any ideads when GB is releasing a Final Bios for UD5?

AFAIK: the Z77X-UD5H version F12 is "final" (not a beta version).
Not to say: there won't maybe be an F13, F14, etc. bios posted at some later time, however.

[sin0822]

how can your BCLk drop to 60? or 70?

what are you using to measure bclk?

I just tried it again i disabled C3/C6

I have it recorded on my phone CPUZ 1.61.3 X64. I can try to post it here not sure if im allowed tho. If F12 is final how long does it take for it to show up on GB website?

[sin0822]

why wouldn't you be allowed?

BCLK shouldn't swing, it might be an issue with the version of CPuz you are using. Does the same thing happen with 1.61.2?

When setting C3/C6 to AUTO BCLK sticks to 100 never drops. Thats wid same version of CPUZ. No biggy cos my main concern is the random boot loops on cold start. Do you still recommend setting both bioses exact same ?

Also Sin hopin you may know why GB changed to purple caps and closed gap between the mem slots and kept quiet bout it and still show blue cap version on there website. Also wanna know if purple cap version has more than 1 capacitor under the cpu socket. Hopin someone wid a purple cap version could help on this one. Also the UP5 does that have 1 cap under cpu socket?

When I try to enter Bios or Q-flash the screen says UEFI at the top and everything below is gone.

Sometimes on reboot the system hangs and restarts in the first 2 secs I think the Bios is corrupt and was going to Q-flash it but won't load Q-flash.

Should I do a bootable USB and try to reflash that way??

That kinda sounds like what happens when i get a boot loop. PC turns on get to that UEFI screen then switches off...then ON black screen ...then OFF...then ON n OFF maybe 4-6 times then it starts as normal. I dont think any bios updates are gona help this situation Gigabyte's Biggest FLAW in designing a board with dual bios. In the coming weeks or days peeps will see the UP7 which has the switch to OFF the dual bios function. This may be the only way to stop any crosstalk between the 2 bioses. If only GB used this on all there boards or stuck with 1 bios that works proper.

After sending my concerns to Gigabyte support on the 21/08
This is the response i finally got today.

Flaw!!!! its bloody fantastic mate gone are the days of corrupting BIOS's & having to swap the chip out, use a bios saver, hot flash between boards etc etc or even worse send your board back to have the soldered on chip re flashed/replaced because you borked it. I know you say you have a problem & fair enough this is what you feel may be contributing to it but come on how can you call it a flaw?

It’s fair to say these things are always being developed & improved & the addition of the switch as far as I am aware is not to overcome an issue its a further enhancement/option....

I have against advice always had different bios's on different chips over many many dual BIOS GB boards & never come across an issue. I think Dino or Sin also mentioned somewhere that matching main & backup were no longer required with z77.

Mate i agree its a great board it would be fantastic if it didnt suffer from the boot cycle problem. What i didnt like is the fact that GB relsd this board when it wasnt really ready. I started on F4 had absolute nightmare issues, all sorts. After shutdown wouldnt start had to pull out power lead. loadsa loops, I think it even killed my SSD. I wasted money on new PSU then more money on Mem, then came the BIOS updates which sorted most of the horrible issues. It could be i hav 1st version blue cap i dont know, yes dual bios wicked function BUT if its gona interfere with stability then whats the point. Ive convinced my retailer to pickup my mobo tommorow swapin for Asus pro. Damn shame cos i really did like the UD5.

This boot cycle problem is something I have seen a handful of people complain about on just about every GB board. I have had it myself on my old p67 ud5 never on the UD5H & sure some BIOS's boot better or quicker etc but for me its always been because the board was unhappy with something settings voltages wise & once found all was well again. Some of these people with problems may just plain have dodgy boards but I bet most are setup issues or maybe something like the BIOS not fully supporting certain hardware.

Again I see what you are saying about the early BIOS's & sort of agree maybe they were or the board was launched premature however all manufacturers do this so there's no getting away from it unless you wait for a board/bios to mature before your purchase.

My board is a blue cap model btw & IMO it’s the best board I've had to date.

I hope all works out ok with the board swap.

[stasio]

New BIOS is out.

New BIOS is out.

Thank you. There’s a serious BIOS error in fan control, I hope they’ve corrected it.

BTW, my problem on the previous page -- BCLK less than 100 was caused by EMI interference from an Asus wireless network card. I removed the card and BCLK is back to normal.

[AVulgarPicture]

is there to be any overclocking guides made for the UP series boards?
i have UP5 here, ive read sin's UD5H overclocking guide, wondering if the mosfet 3dpower control settings should be changed at all considering the major differences in the pwm system.

[dinos22]

previous guides are fine, everything applies the same!

[AVulgarPicture]

cool. i'll keep doing that then.
always hard to tell what i should push on water vs ln2.

[sin0822]

Keeping main and backup BIOS the same will reduce the amount of times the dual BIOS error will come up, however the reason the switch was added in the UP7 was determined way before Z77 launch itself as disabling the dual BIOS can help make the reboot behavior much more consistent(so the system wont have the fully shutdown) and because it will help make OC recovery much smoother, it was actually the idea of the head BIOS engineer.

I think in the future perhaps you could see a disable switch again or perhaps even an option in the UEFI. But then you have to realize that dual BIOS helps a lot with BIOS corruption, which usually occurs with OC or BIOS flashes.

You really shouldn't be getting the db error unless your BCLK OC set from UEFi fails, or perhaps because of the type of CPU and memory config you are using. I honestly don't see it unless i fail BCLK OC from UEFI(windows is okay).

How come they didn't say one word about Thunderbolt ??

[sin0822]

b'/c neither board has it I guess. The UP7 doesn't have TB, it is already a 10-layer PCB, imagine having to add in a 3W controller, about 6 different support ICs+VRM(two DP switches, an HDMI switch, two 3.3 to 18V MUX, and 1-2 phase 3.3v VRM) just for TB. I think the same reason applies to the iTX

[AVulgarPicture]

who cares about TB?

[vailr]

How come they didn't say one word about Thunderbolt ??

They do mention Thunderbolt, starting at 45:15 of the video.

Hi, Im having serious problems with what i believe is my mb. Whenever i first turn on the computer it will get to the windows logo screen and freeze, then i would have to reset computer and then load windows from the safe mode screen in normal mode. Then it would be fine for the day even starting and shutting down loads of times. Then i started getting bios is corrupt messages and it would load from the backup bios. I have taken the board back to where i bought and they have tested it and said its fine. This is my system any help would be greatfull

OS:win 7 pro 64bit
MB: Z77X-D3H
CPU: i5 3750k
GFX: 7850
PSU: Jentek 750w

[ZenEffect]

Jentek PSU might be the culprit here. If it isnt providing stable voltage, or quick enough transient response it can create the issues you are describing. I will get a bios corrupt message if I power off at the exact right (guess its actually wrong) time or if i power cycle alot rapidly.
