Hi,

I have an AMD 7800X3D and a Asus ROG Strix B650E-F Gaming motherboard arriving tomorrow, I am just doing some research before I start putting it together.

I have read that some people suggest to do something called a BIOS Flashback before installing the CPU and RAM, is this necessary or can I do it the way I know (building the pc, installing windows and then updating the BIOS from USB)?

I am slightly worried because I have read that there was a problem with this combination catching fire before the BIOS was updated! Is this still an issue or will the motherboard come with a safe BIOS pre installed?

Thanks

All this is is a BIOS update. The 'flashback' part is being able to do an update from a USB stick if things have gone wrong. Just make sure you update the BIOS as the very first thing you do. You can do it even without a CPU installed.


If you have a UPS then make sure everything is plugged into the UPS, just to be on the safe side.

Thanks for this, I have already got the renamed BIOS file on a USB ready to go.

Unfortunately I have read about this after ordering it.

I would expect Asus to have updated the BIOS that they ship boards with so that it contains the fixes, but I might be mistaken in this assumption. Anyway, so long as you don't enable EXPO/XMP, I don't think you need to worry about it until you can check the version and/or flash it.

Just put the PC together, start it up, enter the bios itself and use the built in bios utility to flash the bios to the latest version before doing anything else, for this you will need the orginal bios file on a USB stick, not the renamed file.

Be aware, ASUS do a 2 or 3 step bios update processes, so it will reboot a couple of times whilst its updating, dont think that when it switches off for the first time its finished and then remove the USB stick, just leave it alone until you are 100% sure its finished, it will switch off and wont come back on again until you press the power button when its finished, I normally wait until im safely back in the bios before removing the USB stick.

On a plus note, out of the millions of people that brought ryzen 7000 and AM5 motherboards, there was only about 5 people that had the burn out issue, and only 2 or 3 of them were on an ASUS board, ive been running ASUS X670e with a Ryzen 7000 since almost the beginning and never had a problem, even with Expo enabled, there was Gigabyte boards and ASRock boards involved in that mess too.

GN reproduced the the issue here, there first board was an ASUS, the 2nd board was a Gigabyte with the 1.45v SOC "We found a bios so buggy with Gigabyte that it can kill a chip accidently": https://www.youtube.com/watch?v=kiTngvvD5dI

Thanks for your reply, ill do what you are saying and update the bios this way.
 
I think bios 1413 had the cpu voltage bios fix which was back in late April, regardless as mentioned just flash bios to latest version as soon as possible and you''ll be fine. Btw I've the Asus B650E Gaming E version and my CPU Soc does not go over 1.24v even with expo enabled with 7800X3D cpu and latest bios 1809 for my board.

Still running great after three weeks :) .

Ok great to hear.

Bit of a different question - what pattern did you apply your thermal paste? I’ve got a peerless assassin heat sink to use and am finding lots of different opinions on this.
 
Safe method would be X type across CPU or if you want to be 100%, I normally spread very thin layer across the heatpipes (depends on type of cooler btw ie exposed heatpipes that mate with cpu surface) on CPU cooler as well, ie where it mates with cpu to fill in the little gaps if not 100% flat. Coolers that have flat surface with no exposed heatpipes where it mates with cpu that you don't need to do this.

I know pea size blob of paste is common on CPU as well but that was more for the old days, X type spread or fine thin spread across CPU works best IMHO.

End of the day we all have our own preference thing to applying thermal paste.

You’d expect that but often the assembly process is so fixed that they sometimes wont ship it with a fixed BIOS.

ASUS are better than other manufacturers though so I’d give them the benefit of the doubt but Id still update the BIOS just to make sure.

(ASrock are really bad at it and I’d always double check one of their products)

I'm going to build my new machine tonight and put the latest Asus bios on a USB stick.

No idea what bios it shipped with, but I it will also depend on how long that stock has been sitting on a shelf in a shop or warehouse.
