Asus Z790 Bios with Microcode update 129 for Intel Raptor Lake Instability

[DannyzReviews]

I'm still running the bios on my APEX Encore from January and have had 0 issues since then so I'm probably going to hold off on doing so IF I see any problems arise. I didn't abide by Intel's/Asus demented VID table and applied my AC/DC LL undervolt.

I don't know if the Intel boss will be able to pay for them to do BIOS updates for long.

[msg]

Waiting for MSI to release it for my 14900k, they release it for some of the MSI boards but not all of them

[rasporilac]

One more question so my bios is old the first one B760 rog strix (using i5 13600k), so when I update microcode will I get update for 14th gen in microcode update too?

[rasporilac]

I have never updated my bios do I need to update some version before new microcode or is this microcode all I need? (Still waiting for b760 motherboards update)

[giovvanieotte]

Im on old microcode and no plans for updating bios ... Tuned performance and thermals myself ... ACDC Loadline 28/55 LLC Medium, core offset -0.055 V, 253W PL1/PL2, CB23 score muti 39840k on gibabyte Z790 gaming X AX @ 13900K, no thermal throttle, stable as hell passing Ycrucher, and CB 10 minutes and 30 minutes runs ...VID MAX never exceed 1.360V, VCORE MAX pek 1.380 .Amamzing performance and low temperatures !

Hello!
Is your cpu delidded? Are you using an AIO or custom loop or direct die for those temps? Best regards from Portugal!

[karintosco]

waiting for gigabyte to update z790 motherboards for my 14900k... Can someone let me know when they post it?

[emirmisel]

what settings did you change to get your performance back? as im on the z790 dark hero thanks

[sometech]

Hi, thanks a lot for showing that! I was hesitating to do that on my ROG 790I + 14900ks. one question though, did you press F5 to reset the bios to defauls after the flash, I m not sure if that needs to be done. I am asking because it does seem weird that ASUS default became Intel's.

[TrueBlade-]

So what settings do we adjust ? MCE ? Intel Defaults everywhere ?

[TalonsTech]

Updated this morning on my Apex White and 14900KS. No issues so far, no performance loss to note. Interestingly my CPUZ was 996. Pretty margin of error for me.

[Demxx]

Well currently the peak voltage i seen on my cpu has been 1.29 on my 13900kf after getting a replacment after my other one died this will truely tell if its a voltage issue or another flaw within the cpu if my current cpu dies.

[mariodevita]

Can BIOS Flashback be done with CPU and RAM installed?

[toonnut]

Im honestly debating to update my bios im on a very old bios (506) and had no problems. Im thinking if it ain't broke dont try and fix. But i obviously want to prevent and unnecessary damage.

[cancerbero]

Do you know anything about when Gigabyte will release the bios update for the z790?

[THEMODSK]

I saw that the temperature went from 38 to 33 after you updated the bios :O did you notice it mr bang4buck?

[gardenia]

You shouldn't monitor VID,
Core voltage (vcore in monitoring application) is what counts. Because that's what is actually fed to the CPU v rail

[bassman]

MSI released a beta of the BIOS with microcode 0x129 as well.
