ROG CROSSHAIR VIII HERO(WI-FI) BIOS 2103 High Instability/Crashes/

[tommy7600]

I had some event viewer errors relating to processor instability(not overclocked) after the 2103 BIOS update, i could no longer complete a Real Bench benchmark or stress test.
I tried a bunch of things, then decided to try bumping the voltage by the smallest increment, and suddenly everything was stable again. I'm not sure why this would be necessary after a BIOS update though.

Where exactly check those event viewer errors relating to processor instability?

I have downgraded my MB from 2103 to 1302 many times The bast to that is to have USB flash on USB 2.0 up to 8GB.

I have 2 x different USB 8GB drives, Both formatted to FAT32, The correct bios file from the Crosshair VIII Hero *non wifi* page downloaded, Unzipped and it still says "this is not a proper bios file" on both the drives.

On a side note, I managed to get a screenshot of the voltage drop, This time it didn't reboot my system but it did freeze up the game I was playing, I managed to Alt-Tab out and grab a screen shot of Hwinfo, As you can see it drops down below its rated voltage of 1.35 which either reboots the system or freezes whatever I'm doing, This did not happen with 1302.

Did you change the file name? And did you that by flashback tool on rear USB? You can downgrade only using flashback tool.

Regarding the DRAM voltage. That's way I have set 1.36. It's more stable than 1.355 and suggested by Ryzen DRAM calculator. Still ASUS should fixed it.

I can't say I noticed any more problems after updating to 2103. Still can't run my old 2800MHz RAM at its rated timings (CL15), which I've reported to ASUS support in January, and kept complaining every BIOS version. They still tell me to send it in for RMA; utterly useless.

Still have crazy high idle voltage when PBO is enabled regardless of settings (1.4-5v). If PBO is disabled it sits under 0.9v, but won't budge from 3.5GHz. Or is it PB.. Two similar yet different things which are highly convoluted in AMD's BIOS.

Tried to get back into overclocking after updating and seeing it wipe my settings and require manual reconfiguring.. feels like my chip is degraded as when I configure PBO to get into the 4.6GHz range on CCD0/CCX0 (used to be able to do 4700 manual; but never ran it beyond testing as I didn't feel comfortable keeping a manual voltage.. $750 CPU and all) I suffer random program crashes and even BSOD's. No voltage touching besides increasing current capability to max. LLC didn't seem to make a difference, but I didn't test all the values.

Continuing to wish I never bothered upgrading and just waited for Intel's response to Zen 2...

You made a good decision getting Zen but it's not AMD, It's board partners, Asus mess around with so much from bios release to bios release, They seem to put a lot more effort into their Intel boards bioses.

Also I doubt your chip has degraded, It's the bios, Way too many voltage issues.

DRAM voltage set to 1.36 in BIOS. In most cases it keeps 1.352 on 2103 bu should 1.36V. If I set 1.35 as it should be, then I can get 1.34 and reboot.

Exactly the same with 2103.

I think that such issues should be noticed by ASUS not by users. Next MB will be probably MSI or other company. ASUS is great when you use Intel CPU. Not so great with AMD

Dropped back to 1302 with my G.Skill F4-3800C14-8GTZN RAM in DOCP and BAM have stability. Move to BIOS 2103 w/ DOCP and assuming you can even boot because it loves 'f9' erroring. Than once you manage a boot you get BLACK screen resets randomly in Windows.

So I'm sticking with 1302 till they fix it which most likely be never based ticket support blocking anything go to bios guys with random bs that has nothing to do with anything. Like what settings are you using, screenshots please and video under 10mb. DOCP and AUTO not like I need to go out of way to find problem with it... Nope nothing fancy to cause it to crash in 2103 BIOS - half-baked crap.

Feel like doing a video it will be 1000mb one on YouTube showing just how bad this BIOS is.

Summary
2103 BIOS not stable.
Black screen resetting in windows and/or
multiple 'f9' boot error
G.Skill F4-3800C14-8GTZN in 2x8 and 4x8 Configurations

Discoverd I'm experiencing RAM issues with BIOS 2103 (4x8 G.Skill F4-4000C17D-16GTZR).
With previous BIOS I was able to keep my RAM @3600 CAS 14, now with the same settings from Calculator I can't do better than CAS16.
Tried to raise VRAM a bit but had no luck.
