This has been my story ever since i got the B2 on release day(with gazillion bios changes), January 9th, up until right now with the new B3 mobo. I'm still using the F1 BIOS tho. I've noticed when you lower the memory speeds it seems slightly more stable. Instead of every cold boot, it does it every second cold boot. If you leave memories at 1333 seems to be booting up fine. Falkentyne keeps saying the new F3 beta fixes all this, but i seriously don't believe him - nothing against you brother, just saying i lost faith completely to even bother changing the bios... :D

ps: That is why im using the multipliers for each core to set up my CPU clock, cause when it fails after a cold boot, this way it only reverts the memory back, but it retains the settings for the CPU multipliers + the CPU vcore. SO now when it says overclocking failed, i just ignore it and it re-boots by itself, and than loads Windows with CPU @ 4.9Ghz and it is rock solid - only the memory is reverted to 1333mhz 1.5v. If I set up a constant multiplier from the top of the Overclocking menu and disable "each core multipliers", than when it fails overclocks it reverts the multiplier back to 34x which is not cool and i have to actually go in and set it up again...

Why haven't you flashed the F3C beta bios??
I told you at least 3 times to flash it! You're still mad about the reboots yet you refuse to flash the BIOS that cures it...
it STOPS ALL the reboots! ALL of them!
Only thing it doesn't stop is overclock failed when pressing the reset button and sleep mode with PLL override, which no manufacturer has a fix for yet.

Yet you don't believe me....

1) F3C stops reboots when you leave the power turned off.
2) F3C stops reboots when you unplug the power and remove the CPU for awhile.
3) F3C stops reboot loops when you change settings.
4) F3C stops reboot loops for using a PCI X-Fi.

It will still boot loop, though, if you use an unusuable setting, though, as it's supposed to do (like RAM timings too low for stability or 2133 mhz RAM on 1333 mhz rated memory, etc).

The only power off reboot (this isn't a boot loop) it does with F3C, is, when you make certain changes, for example, turning PLL override off when it's already on, the board will power down after you save the BIOS settings, as it needs to do that.

I'm serious...FLASH it. Then flash the backup BIOS by alt F12 after you're done (Just clear the CMOS after flashing the mains)
There's a good reason I'm using it. It *works*.

You can always go back if you don't like it.
Flashing the backup BIOS with the main helps even more.

I apologize Falkentyne, i didn't mean to sound like rude :banana::banana::banana::banana::banana::banana::b anana:. You've put a lot of effort into the whole thing and even tested a bunch of stuff for me. I promise i will put F3C Tuesday next week when i have time to play. Thanks for your time, really appreciate it. ;)

Just make sure you clear the CMOS after flashing.
I think you'll be pleased with it.
Board feels almost as stable as my old 775 board now, but I only have basic 10600 cas 9 ram and standard hard drives... no idea what will happen if I move up to 12800 or ssd's...

After the first boot, after setting the new settings, reboot and hold down alt f12 to copy the main bios to the backup bios.
You should have a fully functional board.

Anyone been able to hit up the B3 UD5 with a DMM to see how much the board overvolts (compared to Eztune or HWinfo32?). It's already been proven the B3 UD4 overvolts...

anyone have any idea why on cold boot why my pc will restart 3 times like a bad OC reset, and start up and have everything show same as it was the day before and with no adjustments. after the 1st time of the day it starts like it should

That was fixed for me with the latest beta bios f3c. Which one are you using?
If you're on f3c, did you flash the backup with alt-f12?

I had no problems with having the power supply unplugged for 3 hours and then powering on the PC. PLL override was disabled, however. Are you trying this with PLL enabled? I didn't do 8 hours (there shouldn't be a difference between 3 and 8).

F3c Bios, as far as the ALT-F12 Im really lost as to what your saying ,I did save the CMOS to a profile if that's what your saying, How ever I did find for some reason my Turbo boost tech was enabled and did disabled it. can I save the alt-f12 when OCed or do I need to set to default to do it? under the adv cpu core feature internal cpu pll over voltage is enabled thanks again for your help.

What he is saying is at post you hit alt and F12 then flash your backup bios to the same one you are currently using that way both are the same.

I can do this with the OC setting or default ?

AMD freak, do you have a PCI sound card ? Cause mine hung today after it passed the memory test, when it was detecting the IDE channels. After i shut it off and boot up, it loaded windows but my Sound Card was nowhere to be found, its like i never plugged it in my PC. When i restart again, it detected new hardware which was my sound card...

You can do it at any setting., though it's probably safest not to have PLL overvoltage enabled.

And I just turned the power off for 3 hours, with PLL enabled and 5 ghz, and unplugged the power supply, and when I turned it back on, it came back up at 5 ghz. It did take awhile to come up, though. Sounded like I heard the video card fan rev up twice, so maybe it initialized the chipset twice. Didn't power cycle, though.

I don't see the difference between 3 hours and 8 hours, with the power unplugged. I don't know :shrug: Maybe it's a setting you have that's making it lose the power? Or maybe I need to actually leave it off 8 hours?...

@Turbodiv:
I had some issues with the B2 board redetecting the soundcard, but that only happened on early bioses. I also remember when it sometimes didn't detect the NIC for awhile (or I needed to reboot). I haven't seen that on this board, though.

You can do it anytime, you just press it at startup like where you normally would hit DEL to enter the BIOS, press ALT + F12 instead and it will copy the MAIN BIOS to the Backup BIOS

You see this image ?:


http://s4.postimage.org/19l4b5a04/F3_C.jpg


This image is 100% Rock solid for 12 hours PRime95 large FFTS, linX with newest libraries + AVX + 64 bit, also passes Super Pi 32M no problems at all. I just updated my MOBO to F3C bios (main and back up, + i did a few CMOS resets to make sure everything is perfect). Im Shutting my computer down right now and im going to work, so ill be back in 9 hours and im pretty sure it will not boot up with these settings...

ps: Forgot to mention PLL overvoltage is disabled and all the C-states option are also disabled. Also Turbo Boost is disabled, its clocked with the main MULTIPLIER, not the turbo multipliers. TDP limits and the others are AUTO.

Ive never heard this. Reboot and load optimized defaults after flashing, but not clear cmos.

Nothing but the GPU / ssd is in the white / dvd - Hds in the black

I backed up the bios didn't see any confirm? but at boot hit the alt+f12 and turned off the PLL and see what happens in the morning after several hrs of gaming tonight, its just odd I can reboot several times in a day no problems and boots in less then 12sec and in the mornings it cycles threw 3 times like bad oc settings but everything stays the same as far as settings from the night before. I can even reboot after w7 loads the 1st time in 12 sec Ive ran the f3c bios from 2nd day. its not really a problem but just very odd only after extended hours being off. its very stable never an issue testing or gaming for several hours at a modest 4.5ghz 1.325v

its what I have always done, then load optimized
I have heard this and remove the battery I guess its just what users have found to work for them. like removing drivers in safe mode.

You forgot the /quote
Anyway, this is EXACTLY what I was doing after a flash. Taking the advice here and not bothering to clear cmos...

But I stopped doing that, when I noticed my PCIE running at 8x all of a sudden (just happened to randomly check in the CCC and it said it was at 8x...wth)

And the only way to get it at 16x was to set the BCLK over 100.00.
When I cleared the CMOS, guess what?

It was back to x16 at auto and 99.8 again.
I hadn't noticed this for weeks, because I was usually using 100.03 right away. But when trying to troubleshoot some BSOD's while pushing high overclocks, I set it back...and kept it there later, and that's when I noticed.
(this was on a B2 board).

Summary: always clear the CMOS after a flash.
You never know what lingering thing might be left over from before. Might not be apparent to you, but even the slighest issue could cause something odd down the road.

You have an onboard clear cmos...unlike a jumper, it takes just a few seconds to power off the PSU, open the side cover, and push the button :) One reason I paid more for the UD5 than getting a UD4.

AMD and TurboDIV:
Both of you try clearing the CMOS if you have any issues remaining. You can't blame the board or a buggy BIOS if all you're doing is loading optimized defaults without a proper cmos clear. Loading optimized defaults simply loads preset settings. (you can also go in and set stuff manually too).

More about clearing cmos:
Back in the Abit BH6 days, if you flashed a BIOS, and then restarted the computer without clearing the CMOS, the default CPU voltage would be set to the current CPU voltage you had before clearing CMOS, thus giving you another .3v higher range. This allowed people to bypass the 2.3v limit on 2.0v pentium 2's, by setting the BIOS to 2.3v, flashing the same BIOS on top of itself, and rebooting.
Clearing the CMOS would set the default CPU voltage back to 2.0v.

This is something to keep in mind, if you guys ever have more issues than you feel you should be having....

Just remembered something else, but not precisely; been awhile:
On my P5WDH, when I didn't clear the CMOS after flashing, the board reset the settings, but the saved OC profiles were still there. (but wouldn't work properly). The BIOS version did display the new version, though. When I did clear the CMOS after flashing, the profiles were removed. Also the date/time was reset, so then I knew it was starting fresh.

So if you guys have an issue with the board, that should be fixed after a flash, but still persists, unplug PSU and give the clear cmos button some love.

Thats exactly what i did:
Downloaded the bios, updated @BIOS to ver 2.11 from the twektown forum link. Shut off my antivirus and everything else non essential. Updated my bios through @BIOS than it asked to restart by itself. It restarted, I went into BIOS, set the AHCI and let it load windows. Than i immediately shut the PC off, unplugged the PSU and pressed the CMOS_SW for 10 seconds, than i pumped it for another 10 seconds, than i pumped the RESET_SW, and finally pumped the mobo POWER SW. This all took me like 2 minutes. Than i hooked up the PSU, switched the PSU ON and than i booted the system and immediately went into the BIOS and loaded optimised defaults. After it restarted i immediately pressed ALT+F12 and than the mobo asked me to press ENTER to copy the MAIN BIOS to the BACK UP, and it did that succesfully. Than a message came up "POWER OFF OR RESET", I powered off. Than i pressed CMOS_SW, without unplugging the PSU and wihtout shutting it off, as soon i pressed the CMOS_SW the mobo booted up by itself and than i began clocking my system. I forgot some options on the first round of BIOS changes so i rebooted again and set everyrthing up properly and than i made the screenshot post up there and than i powered off my system. WHen i get back from work i hope it will power up properly since i think i pressed that CMOS_SW plenty enough.

Ok, sounds good to me.
Only difference is that I use spiflash with a dos booting usb flash drive.
Hope everything works out.

Im not blaming the board at all Im 110% happy with it even if it restarts 3 times the 1st time of the day everything is solid, if it happens again Ill try flashing the bios again and clearing the cmos I use Qflash with a USB stick and never have had problems it just the way I learned w/ Asus and it pretty simple.
Im sure they will fix more with future bios.

WOW ! This BIOS really has some magic in it(for now). The PC booted up perfectly fine with the screen shot settings from my earlier post. The bios boot sequence is definitely different with he F3C compared to the F1. Now when it boots up i don't even see the initial window where it tells you the CPU speed and BIOS version, as soon as the screen lights up i see the AHCI sequence which usually comes after the IDE detection with the F1(i disabled the Gigabyte logo). So far im pleased ! :D

Didn't I tell you....?

Now I bet you if AMD freak clears his CMOS, which will flush out all of the old leftover code from previous bioses, he'll be in the ball game too....

BTW I always get the initial screen because I have quick boot disabled. Having quick boot enabled just increases the chances of something happening (like a boot loop)....

I saw someone many pages back who said one of his external devices wasn't detected if quickboot was enabled, but was detected if it was disabled.

Now this may have only been with the B2 revisions, but when I had quickboot enabled (on the B2), I never heard the 30 year old "beep" sound from a successful post...I'm used to hearing that sound when I power on a computer...I even thought maybe the speaker jumper had come out...

Oh ok. So there is a quick boot option than ? I guess i didn't touch it, i just disabled the Gigabyte logo thing.

ps: YEs you did tell me, thanks. I just hope it will boot up properly in the next few days also. :)

looks like everything is good so far with 1st boot this AM. I guess it had something to do with the PLL over voltage being enabled. since I never got the confirm on the backup of the bios. I cleared my CMOS when I changed bios what 2 weeks ago when I got the board. I would like to Thank everyone for helping me sort out my n00bness after the switch to Intel while I learn :up:
