Update 06.11.2014: When using Corsair Power Supplies:

Go to http://www.corsair.com/en/rm-series-rm1000-80-plus-gold-certified-power-supply and click “Haswell compatibility” under the FAQ & Support Tab.

Quote “According to Intel’s presentation at IDF, the new Haswell processors enter a sleep state called C7 that can drop processor power usage as low as 0.05A. Even if the sleeping CPU is the only load on the +12V rail, most power supplies can handle a load this low. The potential problem comes up when there is still a substantial load on the power supply’s non-primary rails (the +3.3V and +5V). If the load on these non-primary rails are above a certain threshold (which varies by PSU), the +12V can go out of spec (voltages greater than +12.6V). If the +12V is out of spec when the motherboard comes out of the sleep state, the PSU’s protection may prevent the PSU from running and will cause the power supply to “latch off”. This will require the user to cycle the power on their power supply using the power switch on the back of the unit.”

Also check out their forums (http://forum.corsair.com/v3/showthread.php?t=118456). Possible that you need a new PSU but at first you could try to disable C7 state (if possible) in your BIOS settings and see if it helps.

 


 

You may know or not that i bought a new system this year. However the Asus x99 Deluxe standby mode seems to confuse some of the components of this system or its the mainboard itself messing around with it.

 

Infinite loop

When i put my system into standby or suspend mode i can’t really wake it from there. When i try to wake it: the hardware responds, fans are starting to spin, harddrives etc, but the system is not really recovering from the standby mode, instead the system goes to Q-CODE bF and sits there until it starts to reboot automatically. Even a 4-sec-press-hold the power button doesn’t help to cold boot the system. The system sure goes down, but it does keep the system to do the bF loop. It keeps infinite (re)booting.

 

Q-CODE: [bF]

 

The first thing i did was CMOS reset but it is NOT necessary!

Instead: turn off your power supply wait a few seconds and turn it on again. Then the system should boot normally.

I already did play with some BIOS settings and there was something strange happening when i enabled ASPM Support in “Advanced->Onboard Device Config->ASPM Support” ….

 

Asus x99 Deluxe standby mode messed up?
Asus x99 Deluxe standby mode messed up?

When i enabled ASPM Support, i was able to put the system in suspend/standby mode and wake it with either keyboard or power button, right on the first attempt. This made me think i found a solution. It did work 3 times in a row. I then wanted to know if i can reprocude this by undoing the changes to see the bF code again and redoing the changes to see a working standby mode, and failed. Disabling and reenabling ASPM Support didn’t come up with a working suspend/standby mode.

 

 Asus Technical Support

I already wrote to Asus Technical Support and the first “conclusion” was, that i may have defect hardware with the aim at power supply.

 

Do you have same or similar problems? Different Q-CODE? Let me know!!

 

Update: Well sometimes its working and sometimes not. And when i try to record it with a camera, take a guess, its working…. to be continued

  1. Negative. I tried to find a solution by not increasing Vcore only. Once i got a post code which indicates problems with CSM. So maybe not only voltages in an overclocked enviroment may play a role here but also Boot-Settings. It become more and more people experiencing the same problem/behaviour. Did you set your Boot-Methods to Legacy only? I couldn’t talk yet to anyone. I was using my system always as Legacy-Only. Maybe this is a point or direction to start with.
    Saludos

    ATM my board is being shipped to Asus because i was experiencing other weird problems.

  2. Thank you.
    I did not touch the boot section,just overclock the system.For almost a month it was working ok and suddenly this happened.It is annoying..Asus shouls see this because searching through the web you can see that indeed more and more people suffer this.
    If any news please let us know.
    Eyxaristo(thank you)

  3. Just solved the problem.Increase memory voltage.
    Everything back to normal.If needed up the system agent voltage Vccsa I think is called

  4. Absolutely,after 6 hours sleep woke up perfectly.
    If you get BF code before this is unstable system,memory related.
    Good luck,let me know if you succeed.

        1. still waiting for my mainboard. i RMA’d it 2 weeks ago. possible that i never will get it back. asus does know that many bad things happened to owners of this board. possible that i get refund.

    1. when you assembled the system and started it the first time, did you make a fresh install of your OS or did you use your existing install? if so, you would be the third person i know, including myself, with a previous install experiencing this issue.

    2. what power supply are you using? if you are using a corsair power supply then you are the third person i know, including myself, having problems like this.

      This is what happened to me, exactly this! You should test some other power supply if you got one!

  5. Asus X99 Deluxe bF error

    This q code usually shows itself after the system is coming out of sleep.You cannot boot unless switch off the power supply,it then boots ok.
    After fighting for few weeks I managed to get rid of it,tested for 48 hours with several sleep and wake up intervals.Not one bF q-code.

    How I did it.

    1.Update/install all drivers from Asus site.

    2.Fine tuned the Vccsa(system agent voltage) .Mine needed +0.162 v on top of the stock voltage of 0.888 v.

    Second step tried before but it did not worked,so the solution is both above.

    Please bear in mind that Vccsa is very sensitive voltage and needs tuning itself.Start from 1.0 v and work + or – @ 0.01 v increments until you reach boot stability after sleep.

    Forget the cold boot,memory training etc , do not touch those,tested in every scenario etc.

    This is my advice to help people fighting with this bF error code

  6. Costas, do you solve the problem once and forever? I have the same issues, but it occurs only on cold system wake up. So it is very difficult to “work + or – @ 0.01 v increments until you reach boot stability after sleep”. I have wake up stability after sleep on hot system using wide range of VCCSA. But I can’t obtain stable wake up on cold system. I realized in my experiments that memory voltage have great impact. Now I use 1.42V on memory on 3000Mhz and 1.1 VCCSA. The system is stable in all tests as AIDA and so on, but not absolutely stable at wake up :(.

  7. BTW. You say to install all drivers from ASUS site. Do you use ASUS AI Suite 3? I do not use this one, because I handle overclock by myself more precisely.

  8. Hi Andrey, i will try to get more into this once more. I didn’t have much time in the past weeks. I did RMA the board already one time and it may happen a second time since i have problems with crystal sound. In the past i also did increase Sys Agent but only by 0.06 V (and the “base” offset) and it didn’t solve it. Maybe i have to go a bit further. Costa said he added 0.162 V to the stock voltage of 0.888 V. But even when you run a not-overclocked system, the Sys Agent will run at 1.2 V in total which means the offset starts at 0.350 +- which means you have to add your V ontop of the 0.350 V in my case it was 0.410 (0.350 V + 0.06 V). I think that Costa just forgot to mention it.
    Start your system at basic settings. Readout the Sys Agent Voltage using ASUS AI and then reboot, get into the BIOS and add an offset (dont forget to add the “base” offset of 0.350 or what ever your AI was measuring) to the base Voltage (0.8 +-) of the Sys Agent. But in the end its not guaranteed that it will solve anything.

  9. Hi!

    VCCSA in non overclocked system will be exactly 0,888V as Costas said. If you see another voltage in BIOS than you use some kind of overclocking. Maybe you even do not know it and use standart overclock preset of X99 deluxe.
    But my system is manually overclock to 4,5 GHz@1,3V (Core i7-5820K).
    As I said above I do not use Asus AI, I just use manual settings directly in BIOS.

    I testing now VCCSA = 1,15V. The issue with wake up not stable and take place only on cold system, so I need more time to say does it solved the problem or not.
