Gigabyte GA-P67A-UD5 Discussion Thread

[TurboDiv]

I pray i got no boot issues. Tomorrow im getting the replacement. I prefer i get a 4Ghz 24/7 clock rock solid w/o any booting issues than 4.8 Ghz 24/7 with booting issues every time i start it up...

The board "appears" to double initialize the chipset after you cut the power completely (like unplugging the PSU or clearing cmos), but it doesn't boot loop by cutting the power anymore. I actually can hear my video card fan ramp up twice and I can see my Astro A40 power light turn yellow two times. But since there isn't an automatic power shutdown anymore, there's no loss of BIOS settings, either. Settings come right up.

Reminds me of the 975X fix that was done years ago.

Haven't tested changing lots of settings with PLL override enabled yet, or with what would happen if BIOS recovery were necessary, but zero problems so far with F3C.

(The board does fully power down after certain profile changes or certain options saved; I think switching PLL override from enabled to disabled will cause a full 5 second shutdown when you save and exit).

No power cutting boot loops yet, though.

I have a couple questions... got my system together and tried a little OC and for some reason CPUZ 1.57 keeps changing core speed am i doing something wrong? #2 sometimes it seems it will not go into bios screen when hitting DEL on my USB keyboard #3 what are the basic changes made in the Bios to OC such as CPU multi/CPU Vcore etc thanks for helping a intel n00b

Im on B2 but I don’t think it will make much difference, I get CPU-Z crashes maybe 2 in 10 fail to start but work fine 2nd time I just figured it was due to trying to open CPU-Z early before the rig was fully loaded. I don’t get this problem if I'm a bit slower to open programs after reboot.

I think the not going into BIOS is BIOS specific some of the BIOS's I have used go in easier than others some like me to hold del down some like only one tap some display "prepare to enter bios" when del is hit some don’t. I find using IDE rather than AHCI to be better for entering BIOS especially when you are messing about in BIOS many times. You can always switch AHCI back on when you have settled on some settings & don’t need to enter the BIOS quite so much.

As for OC settings most boards/chips appear to do 4.5G on auto maybe a bump in vcore, why dont you see how far you can get save it in BIOS & start changing things to see what works for you. If you get stuck there are plenty here self included just tell us what's happening or not & we'll see if we have an answer.

[autoct]

Need o.c help

I've been able to be stable everything auto (vcore 1.37) up to 48, but can't get 49 stable with vcore up to 1.40, windows failed during the first intel burntest, I get a multicolored screen but no bsod. My cpu pll overvoltage is enable and llc set to level 1. All other features are disable. I only manually change the vcore, all other voltage leaved to auto.
Any Idea or I just have a not so good chip.

[Falkentyne]

Multicolored screen? Huh? >_> Sounds like a BSOD that failed to happen and instead it crashed the display driver or something, or wrote random pixels to vram. who knows...

You're using LLC1, so raise the vcore in the bios to 1.425v. It's going to drop under load and wind up being something like 1.390v.

[dinos22]

use a multimeter to check volts rather than rely on software as its not really correct

When are you getting your B3? It's alot more stable. Only seems to ever boot loop if you try to S3 with PLL enabled (which disables the PLL when powering back up and causes boot loops and could potentially require a cmos clear to get out of, then the board goes right into windows instantly as if nothing ever happened).

Also, my costa rica 2600k hasn't "degraded" yet with the fixed LLC1...no idea if that's because of no more overshooting, or because of a better chip...

[autoct]

I put LLC to level 2, and my 49 multi is stable vcore 1.37 in bios, it raise to 1.40 under load with temp around 80, that will be my 24/7 clock

I was thinking what Falkentyre said.... sure it could be anything but the only times I have had a multicoloured screen was over cooking my ram & it was patchy with odd characters mixed in & full screen of multicolour blocks when my video card has the 2 bob bits again due to pushing it to hard or without enough voltage.

Was all up for it until I heard some people having issues with B3... My B2 is functioning spot on as it always has done & I'm still stoked with its daily performance so no hurry to change it really. I think I'll wait for the next board/chip then do something about it unless it breaks before then!!

Interesting about the degrading but I've never had a chip that didn’t settle/degrade at least a bit, the trick to note this for me for what practical value it serves I don’t know is to record your chips 1st boot voltage & be able to find its max real quick before it degrades without you knowing it.

I basically booted my new chips at stock set a few things up & multi at 45 then v quickly upped the multi 1 at a time noting the required boot into windows voltage from 45~max within 20 minutes of powering the chip up. My chip/chips all needed more voltage after minutes/weeks to even boot into windows & or run linX as they had before. My current 2500K needed I think something like 1.26 on 1st boot to get into windows at 5G!!! & did 5.5 the first time under 1.4v

Thanks C-N for the help after many years of AMD/Asus its all new to me I guess its just a small learning curve. I did find what seems to be a solution to the bios deal if I hit DEL only once during the loading of the drives it works over all Im happy with everything so far was able to bump it up to 4.8ghz with a slight bump in vcore http://valid.canardpc.com/show_oc.php?id=1731130
with a lot more reading and testing I see no reason this wont run 5.0ghz.The one thing that scared me when I got the board was to find it had a Foxconn socket, had a bad experience one time where it lets say melted. after looking around I found that the CPUZ issue was only the C1E-EIST settings

Well, that's why I did an advanced RMA. That way I had both boards so I could make sure I was happy with the B3 before returning the B2.

And I've had no problems with mine. Was definitely worth the trouble of the swap, and my B3 is light and day ahead of the B2. I think you'll be pleased if you swap. But it's up to you.

If you do the swap though, can you test some voltage readouts for us?

[autoct]

I have a problem with my RAM. If I try XMP profile everything load fine into the bios (6-8-6-24) but show (8-8-6-24) in windows or memtest86.
I've try many different setting but always load wrong from what in the bios ???

Good thinking & sure I'll take some readings but maybe someone here that has a B3 could do them now if you need them now

I have seen this a few times cant remember how it happened or the fix but for now the only thing I can think of is both channels are not setting the same. Maybe when you set the XMP profile you have something other than auto/quick set like expert & the profile is only loading in channel A. Other than that try setting something slacker like 8.9.8 / 9.10.9 & see if memtest/windows reads it right. I have also seen the same on other boards when I push tight timings one channel will blow out/not register etc as either the dimm is weaker or the channel needs an independent tweak to get it to match others (happened a lot with DFI)

[TurboDiv]

SO far so good. The board came in with F1 bios. Everything went smooth, windows detected all stuff. The clocks remain about the same as my previous board. I gained a few degrees from the whole deal- probly cooler mounting went smoother. LLC1 is way more aggresive this time around. Befiore 1.55v LLC1 gave around 1.408v under load. Now its more than 1.55v under load at the same settings - that's massive difference ! Im still experimenting. The cold boot (overclcok failed) message came in only once when i pushed 5 Ghz 2133mhz ram, other than that it behaves more stable than my previous board. I have to see if the cold boot (overclcok faild) message is still there, so far i had only 1 power ON cycle from last night and did not give me "overclcok faiked" message upon boot. Lets hope it doesnt have that problem, ill find out in a few days.

[Falkentyne]

Flash to F3c beta bios. F1 still boot loops and can report overclocked failed, when loading some profiles or when changing certain settings (especially when going from a high to a low overclock), and f3c mostly prevents that, by usually doing a "soft" internal cycling instead of hard power cycling (which also helps it keep the bios settings). (The only time when f3c will boot loop uncontrollably (may require clear cmos) is if you try resuming from S3 with PLL overvoltage enabled, and it seems to automatically disable the PLL after an S3 resume=thus the chip can't boot if its beyond the multiplier wall.

Confused about LLC...You sure you using LLC1? Did you clear the cmos before you installed the board? Because everyone who has used a B3 UD5 says that only LLC2 overvolts, and doesn't overvolt that much. Your LLC1 should have smaller vdroop, but should NOT overvolt.

On the B2 boards, LLC1 with 1.55v would be over 1.60v under load, so I have NO idea where you got 1.408 from (and I didn't try the very last B2 beta bios, as that had PLL override removed)

Use HWinfo32 to monitor your voltages on B3.

B2 boards were overvolting a lot with LLC1.

1st round of testing Don't know how good they are.

[flesheatinvirus]

Not bad, what batch 2500K?

[TurboDiv]

Same issue with this board as my old board. When the PC is shut down for a longer period of time (~8hrs) upon boot tells me "Overclocks failed" and reverts the memory to 1333mhz and i have to log in BIOS, save and exit and than it boots up fine with the proper settings(2133mhz). Annoying as hell. Looks like im gonna have to hunt for some P67 certified memories. Sad cause these G.Skills are running perfectly fine when the mobo decides to boot up properly with them.

What BIOS version are you using? F3C?

if you can see anything I missed let me know, Im still learning Intel would like to see 5.0ghz+ 24/7

Please flash to F3C.
I just left my computer turned off for two hours, with the power supply completely unplugged (rocker switch was off), so the board had absolutely no standby power going to it.

I just got up now, flipped on the PSU switch, turned on the board, and it powered right up at 4 ghz. I tested this just for you.

Two hours with the AC power completely cut off should be no different than unlimited time with AC completely cut off. On the B2 board, if I powered the computer down and left the PSU turned on, it would power up and keep the settings. If I unplugged the mains after powering down, it would say overclock failed.

I haven't tested the reset button yet.
Ok I just pressed reset for you.

Pressing reset causes the board to lose the overclock settings and say "overclocked failed.", then it powers down for 5 seconds, powers up, then you can get into the BIOS. It does not do that "power up for 3 seconds, with a quick power down, then power up again, though. So definitely don't use the reset button Use the power off button instead. (especially important after a BSOD, since I usually have a habit of pressing reset after a BSOD).

Hmm...the RESET button might still have a use...
I can see it PREVENTING the board from infinitely boot looping if you try to suspend with S3 with PLL override enabled, and immediately allowing you in the BIOS (after it loops once), instead of having to clear the CMOS...

Same here all running like a champ & nearly into its 5th month of rapeage

Have fun with those new sticks bud & keep us posted

[TurboDiv]

Im still with the F1 bios. Ill flash it when i get home to the F3C. Did you flash through Windows @BIOS or through Qflash ?
