You would be correct sir the waking from sleep bug is a problem in intels own firmware code, last I heard intel were aware of the problem and exploring possible options for a fix.

Do you have details what this Intel bug may be? Other then the PLL Overvoltage issue? I have had no sleep issues on Asus boards running stock or overclocked. Wondering if this may be something will just appear out of the blue one day.

[MacClipper]

Mate, that its great but it doesn't work for me on an Asrock Z68 Extreme 4 with the CPU overclocked to 4.2Ghz (no voltage change or anything just a change of multiplier).

Can I see your BIOS settings?

Should be all here

It's not a issue that will just suddenly crop up one day I wouldn't think. The issue would seem to be fixed with Z68, and given the maturity of the UEFI on the P67 Extreme4 I'd be surprised if the bug still exists on that board. AFAIK every bug I have reported to Asrock the R&D team has fixed

[EzyRyder]

Well, it is now going to sleep properly ... don't know what I changed there but its now working fine. Strangely enough I went back to stock speeds and the system wouldn't wake up from sleep first time I tried so had to do a reset.

I assume the overclock is stable after 12 hour prime and 3 hour linpac though. I think I can probably do 4.3 Ghz at stock voltage as I managed to do 4.4 Ghz 7 hour prime stable before one of the cores crashed.

Overclocking.. fun isn't it? On another note good news Z68 owners I just this minute answered the door and got the Z68 Extreme4 I must say its rather impressive when you open that flap up and lay your eyes on it for the first time Pictures and a review are also inbound I'm just waiting for my new temperature gun to arrive for a portion of the review I'll be doing.

New BIOS - 1.4 released!

Notes: Modify fot GPT mode.

[Ket]

Updated first post with some UEFIs.

[aicjofs]

When I changed BCLK from 100 to 100.1 I noticed the UEFI info screen will say 4848Mhz for CPU speed with 48 multi instead of 4805. Cosmetic bug of being off a decimal space? The CPU really runs at 4805 so no big issue, just wondering if its known or others have the seen it.

[Ket]

I'll check it when I have the Z68 Extreme4 up and running Just waiting on a temp gun to arrive to get everything done in one go

For anybody not being able to wake from sleep with a high overclock on the Z68 Extreme4 it's recommended you update the UEFI to version 1.4, it has been extensively tested and this problem can no longer be duplicated. It would seem intel or Asrock found a reliable fix and implemented it with UEFI 1.4

[radier]

How about the same solution on P67 Series?

Thanks for that Ket, I have been trying to overclock mine to 4.5Ghz stable with low volts but I am yet to upgrade to 1.4. Will do that in the next few days.

By the way the eSATA problem is still there

[Ket]

How about the same solution on P67 Series?

I'll bring it up in my next chat along with the eSATA issue if it's not been fixed with UEFI 1.4, but please keep P67 talk in the P67 thread

[Falkentyne]

Ket, please, don't spreed this bs about Intel SB sleep bug. With your reputation here people trust you. Asus and Asrock are the ones having sleep problems with SB. If that's coming from your Asrock contact tell him to check with Gigabyte about that.
No offence, man.

Um, Ket is telling the truth.
It's a BUG in Intel's firmware. D1 stepping chips don't even support internal pll overvoltage in the first place.

Gigabyte did NOT fix the issue. You seem to think they did--they did NOT. I have the board. I TESTED the bios. They simply did a BAND AID for it. You want to know what happens with latest bios?

1) GO into sleep
2) wake up from sleep. Fans spin up for 5 seconds.
3) board TURNS OFF.
4) Board does a COMPLETE REPOST to BIOS, cpu and RAM count, just as if the board were completely shut off.
5) You boot to the OS choices menu (if you have one).
6) Windows says "resuming from standby".
7) It loads faster than if you loaded it manually, but NOT by much. And the hard drive SWAPS forever ...it's actually faster just to power off the board and power back on, due to the swapping.

All Gigabyte did is make the board repost as if it was powered off (it actually does power off), to reinitialize the register which controls CPU PLL overvoltage.

It's not a fix at all.

If you want a real fix, contact Intel.

Um, I thought you were the one with no sleep problems too... Apparently I'm the only one then.
But let's not go off topic here.

Thanks for the clear, informative post. I'm sure anyone a little confused about the sleep bug will find this very useful info

It would seem intel or Asrock found a reliable fix and implemented it with UEFI 1.4

So you are stating that this board will wake fine from S3 sleep with PLL Overvoltage enabled?

[Ket]

UEFI 1.4 was extensively tested with a 2500K CPU. Every possible combination of options was tested and the problem can't no longer be duplicated with the new UEFI, so based on that, yes, the problem should be fully cured now

[Wendy]

I have this board with UEFI 1.40, and I have no sleep issues, with PLL overvolt enabled @4.8GHz.
The board sleeps and wakes with no problem.

Boot drive is an OCZ RevoDrive X2, I'll try it later with a Vertex 3.

[EDIT]
Confirmed working with OCZ Vertex 3, and no issues with sleep or wake.

[Ket]

Good to know, looks like we got that one nailed too

[Ket]

@EzyRyder, have you tried UEFI 1.4 yet and has it fixed your eSATA problems?

[EzyRyder]

@EzyRyder, have you tried UEFI 1.4 yet and has it fixed your eSATA problems?

I haven't mate, I should be able to do it sometime this week though

I need to order a new USB stick as my old one gave up the ghost so no FAT32 devices on my posession to do the update!

[Ket]

You could update through Windows... but I think we both know if you did that I'd be forced to break out the shaky head smiley at you

[Ket]

Fresh off the press! One of my Asrock contacts has today sent me a shiny new UEFI for the Z68 Extreme4; 1.4A. The change is a clever little bit of code that will automatically detect and set any XMP profile that has been pre-programmed into the memory modules SPD data. Anyone that tries this beta UEFI could you please post in this thread letting me know if your XMP profile automatically got loaded? Thanks

I'll upload the UEFI once the file hoast resolves its technical issues, it'll be available to download from the first post

ED - Link is now live!

[EzyRyder]

Nice one Ket. Not a deal breaker for me though as it only takes 5 seconds to go to the BIOS and change it to pick the XMP profile. Got my USB pen today, I will be flashing to the latest 1.4A bios anyway so will let you know how it goes!
