I've also noticed that the M4E I'm testing at the moment tends to loop the memory initialisation more than once. So, it's possible to see it go from 00 to 6x, back to 10, back to 6x and repeat. Just ignore and hope it boots.

 

Oh, in case you have lock-up at 63, try to shutdown PSU and power it on quickly again and boot again. Sometimes it goes straight through. With ASUS boards, when it says overclocking failed: F1 -> bios -> F10 + save and it should work just fine.

 

For the P8P67 Deluxe I quickly tested today: looks like loading settings from the OC profiles doesn't work. Clear CMOS, set everything in bios and reboot works perfectly.

SB is funny. When you enable speedstep you will be stuck at code 63. You can get over that by pressing the clear cmos button very quickly in the I/O side of board. After that the board will boot back, so you can get back in to bios. If the board boots for some reason with your overclocked settings :) you will be stuck at middle of loading OS.

 

If speedstep is disbled I see the same AE code, when it should load the hard drive.

 

So the issues are exactly same as Massman and others said. It might be some bios issue with some turbo ratios. I hope it will be fixed soon. If it is not bios issue and it is mostly related to CPU, then it is quite easy to see what your CPU can do.

 

Have someone found any solution for the issue described above?

 

E: and the board is of course Maximus IV Extreme

For the Maximus IV Extreme, you can try this:

 

- set everything in bios

- save settings

- hope it goes through

--- if 63: quickly power off/on PSU and just boot again (repeat if necessary)

- boots up 75% of the time with 'overclocking failed' settings -> F1 (bios), don't change anything just F10 (save) and reboot again

 

AE is indeed when loading the drives. It's also a sign of the max of your CPU; you can work around the AE and get the boot menu, but OS loading will fail because the all cores are stressed.

 

Also, I often have issues booting >1.55V vcore

 

For P8P67 Deluxe,

 

Don't use bios profiles to save you clocks, it didn't work properly here with the PLL bios. I could get the highest clocks only with clear cmos and setting everything manually. Loading a bios profile returns 63 all the time.

It is easier to just hit the clear cmos button in the other side of the board when you see 63. Just let the lights go off and boot immediately. It saves time and works every time and you don't loose any settings, but you will get back to bios.

 

But if you get the board to boot, it will most likely fail during OS load anyway in that case.

Guys,

 

I'm having a problem with booting my PC. It stops at code D6: no console output devices are found.

 

This is my system:

 

ASrock P67 Extreme 6

Intel Core i2500K

Corsair CMX8GX3M2A1333C9

Seasonic X-660 PSU

Powercolor HD4850 video card

Samsung 1TB HDD

DELL 20" TFT monitor

 

I've double checked the installation and I cannot find anything wrong. The video card, monitor and HDD come from my previous system and worked well. The other components are brand new.

 

Thanks for your help!

Hello,

 

I've got problem with asrock extreme 4 p67. I can't enter the bios. I press f2/del and then I only see black screen with letter "AB" in right corner. AMI shows "0d" code, what means nothing.. Please help me. I've got this MOBO since 2days, and it's broken..? OS is runnig perfecly, no errors.

 

i5 2500k

4gb corsair 1600

MSI HD 6850

Chieftec 650W

 

Sorry for my cheap english.

Manja , did the motheboard work with bios 1.20, i see you have now bios 1.30.

Could there be this problem appear because a bad flash bios...?

Flash the bios again with Instant Flash...With what bios you have this problem?

Can you flash back the bios 1.20?

Did you tried to do CLEAR CMOS to see if it does anything...?

Remove boxes, scanner, imprimant leave only the mouse and tastature plug the monitor to DVI if you have HDMI and see if the error appears again...

1:20 I returned ... No problem!

Clear CMOS as I did and everything off, but at the same BSOD when a win logo

Bog_xdan thanks for your help!
