I was googling this problem, and it seems GPT partitions are the issue, BIOS flashback can only work on MBR right?

i have file name extensions on, and it's C6H.CAP :)

Yup that's how I always do it. it stops flashing fast like 3 times then it goes solid.

Not sure what's going on, but BIOS flashback on my Crosshair VI Hero is completely borked. It won't install any BIOS i throw at it. I've tried several, renamed it to C6H.CAP and nothing, get 3...

Hey Shimano, anyword on a new BIOS for the C6H??

7501 has been a very weird one, specifically, if I reboot my system, the POST is glitched, where i can have a stable system, reboot, and then i'll...

wow congrats man! Amazing that a x370 board can hit 3600MHz.

ok so I legit fixed all my memory issues straight away. Turns out, Asus overvolts the CLDO VDDP voltage WAY too much, at 1.1v. I took the DRAM calculator's recommended 0.9v and stuff is running...

Strange, then for me, in order to run my XMP profile without crashing, I have to increase my DRAM voltage from 1.35v to 1.38v.

That is so odd, cause for my RAM kit at least, disabling ECC mode worked for every AGESA 1.0.0.3 BIOS until the ABBA one with 7501. With 7501 i have to run ECC mode or i'll get crashing.

ok so I solved the problem, so in previous BIOS's I had to always turn OFF ECC mode in Zen Options to make my system stable. Now with 7501 i had to put that back to enabled (auto) and now everything...

Update, getting freezing again and restarts shut down and start up the computer again. ugh.

Ever sense i did this, my system is much faster, no glitching (so far), and my restarts don't shut down the computer and turn it back on.

So I narrowed my freezing and weird boot up issues on my C6H, with the latest BIOS, down to memory.

I went and got timings from the Ryzen DRAM calculator and it fixed my problems. (I left my...

What are you talking about? I don't understand. for 1st and 2nd Gen CPUs, they only need the last AGESA 1.0.0.6 BIOS they released which was a while ago.

Of course with 3rd gen, stay on the most...

Nope not yet, wait until BIOS updates get mature for ryzen 3000 which will probably take another 2-3 months.

Honestly not sure why you are even on anything newer than AGESA Code 1.0.0.6. Anything...

If you're on a 1st Gen or 2nd Gen CPU, not sure why you would want to use any BIOS newer than AGESA 1.0.0.6. That BIOS is the most stable BIOS so far and is fully mature for 2000 and 1000 series CPUs.

Try sfc /scannow in elevated CMD. That'll fix windows corruptions.

Luckily all it does is make the startup a little longer, not like it is crashing anything.

Strange, try maybe a 2.6sec fan delay?

Also guys, this BIOS still has ECC mode enabled. So make sure to disable it in AMD CBS options.

7501 has been pretty good, still shuts down and boots up...

So I'm on ABBA with the 3600, not much of a difference. (C6H)

4.15ghz single core turbo, and 3.695GHz all core.

EDIT: Sorry sorry i mean 3.965GHz all core. Not 3.6.

That would be very odd if that was a beta BIOS, cause hardwareluxx seems to only be showing official BIOS updates.

To be fair, this is also a problem on the C6H I cannot get a perfect 100.00 BCLK it is always at 99.98 whether on auto BCLK or DOCP.

I'd wait until more mature BIOS's come out before making a full conclusion.

But according to AMD, seeing even 1.45v is okay. So good voltages seem to just be opinions as of now. (I mean stock, I'm...

Double check that ECC mode is disabled guys. Every single BIOS for 3rd Gen Ryzen I've used has ECC mode enabled by default.

7401 is rock solid stable for me once I disable ECC mode.

That's an old bios now, 2801 just came out a few days ago. I suggest you install that one.
