Okay, that sounds fairly reasonable. When all else fails, just replace the BIOS Chip.
Uhm, were is that BIOS chip at on the ASUS ROG Rampage VI Extreme Encore board again? Does anyone know? I looked for mine.
Maybe under one of the board's shroud covers? My board manual had nothing I could find for where the BIOS Chip is.
Hmmm, I thought I might find some Chip ID type part number to order one.
So, we ask ASUS Support. What part number is the BIOS chip and where can I buy one?
Answer: ASUS no longer provides customers with the BIOS chip.
I guess it is back to the ASUS FAQ Support for BIOS fix steps.
BASICS: Start by unplugging the PC. Use the Clear CMOS button. Hold it down for like 30 seconds. Didn't work?
Take out the CMOS battery for 30 seconds and replace it.
The steps move into more extreme steps like remover all the peripherals for the motherboard. except for a single RAM stick. Boot it and see what the error postcode is. Take out the RAM stick and see if it POSTS a MEMORY ERROR as it should.
You can try using the Flashback and USB with the BIOS version you started with. ASUS Support download likely has your original BIOS to download or the next version above it to replace what you have that's not working. Plugin the USB with only the BIOS file version on it into the designated slot on the back of the motherboard. My ASUS ROG Rampage VI USB slot has a white square outlined around it with BIOS in print on the top. So, yeah I know, kind of a no brainer there.
You plug in the USB and hold down the FLASHBACK button. My motherboard manual said to hold it for 5 seconds and wait for 3 flashes. Oh and if it flashes 5 times it failed. All I know is that I ignored the flashes and held the FLASHBACK button down long enough until it started to load. That was how I managed to get the Updated Successfully screen.
Sure there is more to try and do. But too much to type out here. If anyone wants the Support Links, reply and then I will look it for you to post.
Go do crazy some place else, we're all stocked up here!
