September 21, 2016 - on bios.u should disable thunderbolt support then its ok Thank you Nehalem_1 this solved the bf Q code on my Maximus 8 Extreme, now I get AO once windows loads. @Chronioum: I know this post is a little out of date but I got this error 6F or bF running 4 x 8gb Dominator platinum CMD16GX4M2B3000C15.

March 6, 2024 - Had another bF Q code this evening. Happens very infrequently and only with a reboot. It just sticks at bF and then shuts down. I hit the power and went to the bios and increased the SAV another 0.01V. I now have the SAV for this memory at 0.900V. As Praz stated, the memory is OK as I ran memtest 5.01 again-2 passes with no errors.

Here is the discussion at the ROG forums, its for an x99 system but the codes should be the same https://rog.asus.com/forum/showthread.php?54828-Memory-Problem-slot-D1-Q-Code-6F ... This is a bit old, but did you figure out what this was? Are you sure it was 6F and not bF? The 6 that Asus uses actually has the horizontal line at the top of the 6 present, while the b is lower case. ... Yes I figured it out a while back,it was a bf the error code readout should have used a capital B the small b looks like the 6 also.Thanks for responding.

September 1, 2020 - Thanks. I will give that a go. It's strange removing the overclocking, which has been running for years, has fixed it for now. I was thinking memory or CPU (but guess the mem ok somehow overrides a memory check so memory) and hope it is just a matter of reseating it.

... On most X99 dual-socket boards: • CPU1 must always be installed first • CPU2 will not initialize unless CPU1 is fully functional · Check the motherboard manual or silkscreen labeling to confirm which socket is CPU1.

March 7, 2024 - so guys i was encoding and got a bluescreen. Hit the retry button, lower the cpu multiplyer a bit and now i only get a 6F error in the MB - 567045

October 16, 2021 - I am getting error code bf or 6f on my Asus x99 motherboard. It's only detecting 16gb ram out of 32 and as of today it's only detecting 8gb ram. All 4 ram stick are working fine when plug in a different slot one by one. Is it a motherboard issue or some power issue with the ram?

March 7, 2024 - Maybe Memory related! This may help. https://rog.asus.com/forum/showthread.php?61692-Q-code-6F (Note: Q-Code bF/6F is okay on my ROG VIII, usually associated with Thunderbolt and disappears when disabled.)

March 6, 2024 - On +0.08 I couldn't post no matter how many times I tried, I think this was just short of being enough voltage for the last DIMMs to be stable but enough that the channel wouldn't be closed. Then the magic adjustment number... +0.1! This gave me a total System agent voltage of 0.960 and I have 16GB on every boot, with the bonus of the Q-code errors every few boots going away (the 6F error had returned again just after my last post).

Alright, did it and it works now for some reason.. its odd that it works now by just reseating them all.. Guess Hawkstorm will be right, if i get a a black screen with the same error code's again, we will see.

April 22, 2015 - Google finds "reset bios, go into setup, you will probably see capacity of dram lesser than actual. go into dram timings and see which channel has all timings at 0, this would mean that you would need to shut down and re-seat those sticks." How do I go to dram timings?

June 6, 2016 - I even cleared CMOS (both by clicking button and removing the battery for 15mins) but it didnt fix it. Error code is still present ... 1| Is your BIOS up to date? 2| In your manual, page 1-29, System Agent DXE initialization (System Agent module specific).

September 2, 2020 - Anyone know what could have caused this? Pc would power up, show this error and then shut down. No display or beeps etc. I tried a different graphics card to no avail. Some reading led me to try the MemOK button which made the pc boot, but needed to be used for each boot. I reset the bios to get...

August 11, 2024 - Step 3: If this can’t fix the issue, then inspect the PCI-E Pin on the motherboard and Graphics card for any dirt. If present, clean it thoroughly before retrying. Step 4: If the external Graphics card has a power interface, ensure proper connection. The following error codes indicate other abnormalities like the boot issue or issues with external devices with the ASUS motherboard:

June 9, 2021 - The error occurred about half of the time they rebooted their PC, but it had never happened to me before. There was another post about the same issue but they had different specs than I did. The fix is at the bottom of the page, but I strongly suggest reading this post! For the uninitiated, some newer motherboards (such as the ASUS Crosshair V Formula-Z) have small displays attached to the board itself, which show codes that can help users diagnose hardware and BIOS-related issues.
