Gigabyte GA-P67A-UD5 Discussion Thread

[stasio]

got a question, did some testing today to drop temps a little now summer is about here and noticed some cores are warmer then the others as much as 8c
weak core or bad mount, normal? the amb temp is 32c/79f- 4.53ghz@1.275v bios,/QPI/VTT@1.76

QPI/VTT@1.76 ?!
Use HWiNFO32 instead of System Info and install CPU-Z 157.1.

Ok first of all,
Please flash to the NEWEST beta (F3G) for the UD5
This will stop the boot loops when you enable PLL Override.

F1, possibly F2, and all the B2 version betas had weird bugs when PLL is enabled.

Those bootloops are fixed on F3G beta.

Ok, so there is an improvement from f3c? Thanks for this

I thought the only difference between f3c (which I have with cold boot issues) and f3g was:
'Fix: remove Floppy Support
Fix: BCLK 100'

Will there be any differnce between f3c and f3g in respect cold re-boots with pll enabled?

Well for what it's worth, I didn't have any boot loops with F3C with pll override enabled. But I didn't do that many boots with it enabled. But at least I was able to SAVE bios settings to enable it. Back on F1, when I was, for example, at 4 ghz and I decided to set it to x50 and enable PLL override and "save and exit", it was like a 50/50 chance if the board would boot up at 5 ghz, or would turn on, turn off after about 10 seconds with no screen (no POST), turn on again, show 34x100, then turn off again, turn on and say "system has been reset due to overclocking or error in voltages", then TURN OFF AGAIN right after that screen, then turn on, and then finally allow me in the BIOS.

I never saw this with F3C.

I did several more more vcore settings with F3G and setting various voltages in BIOS around 1.45v to 1.55v with PLL Override enabled, than I did with f3c, and each time I set them, it accepted the settings, and just rebooted normally. I never saw it boot loop (well, not yet).

The only (three) boot loops I've gotten with f3g were when I pressed the RESET button on the case.

Gigabyte does not all ways list ALL changes made to a bios. Only ones they feel are a MAJOR change. What they think is a MAJOR change may not be MAJOR for all people. Always suggested you use the latest bios for Gigabyte boards.

Ok, guys, thanks for the help; testing f3g now. Hope it starts in the morning Working well in stress testing and warm boots thus far! Will let you know how it goes.

Sorry bout that Stasio I seems to have missed a 0 is 1.076 better
