Maybe not relevant for too many, but Phoronix tested the new microcode across a number of benchmarks, here. Overall, the difference was -1.1% in performance, though the individual tests varied from slightly faster to as much as 11.8% slower.

Hope the voltage was better than the recent post in this thread- confusing times!
 
My report.

MSI Z790 blew a cap. Sent in for RMA. Received board. Still shutting off. Flashed Beta and then became unstable. Horrible stability. But wasn't shutting off anymore at least. Call MSI, they blamed Intel. Wait for Bios update yada yada.

Pulled 14700K from Z790 and installed to older Asus B660-G (with clock gen) and was on Bios revision 2212 ME 16.1.25.2020v2 AlderLake and 13th Gen supported. Posted board and 14700K reading was 1.7v (ov protection enabled, viewed via bios) immediate shut down and Flash back Bios Version 2603 ME 16.1.27.2176 (X112). Posted board and 14700K operation was normal. Around 1.47v via bios (idle load) and posted windows tested.

Cpu is fine. Runs all programs and benchmarks as intended. Full 253w. Start with Air cooling and ensure 100c load testing. Passes all benchmarks, short duration Stress testing (Using F@H right now as I type this).

The MSI Gaming Plus wifi Z790 board is Fubar as far as I know.

The motherboard was used for DryIce and chilled water cooling. 14700K Pc-5.8ghz Ec-4.7ghz benched fine. Nice and stable. Had no issues until the board shut off. And I feel it may be totally unrelated except for the fact that the bios update eliminated the board from shutting off. Or coincidence.

Was running ME Firmware ver: ME_16.1.30.2361 when the crash happened. (the board didn't turn back on, so RMA) Got the board back 2 weeks later. Updated to ME Firmware ver: ME_16.1.30.2361 which was released on 2024-05-31. ""Replaced MSI's own tweaked system power settings with added Intel Default Settings, and users can still optimize system performance with alternatives from MSI.""

This helped none. No new bios released for the board since above date.

Just happy the CPU is just fine. At least in the B660 board and early ME firmware, it's fine. Nice and hot, just like a 253w Intel chip should run. Swear it runs better with more v-core. Not sure what all the hoopla about under-volting is all about. Just get better f/ucking cooling...... it's 860BTU/hr at load. Watcha expect?
 
Ooof. Sorry that happened man. Sounds like your board crapped out.... doesn't seem like a CPU issue if it's working in other boards though... weird.





FYI, I installed the BIOS update..........problem is, I never benchmarked anything before so I have no idea about performance before and after on my daily driver. I'm buried in reviews trying to get cleaned up before the new releases...

Is there SW that runs in the background to monitor voltages while gaming? I can’t imagine there isn’t by now. I haven’t updated yet so I’d be curious to see what before and after is like.

Thank god I saved my old rig from 2010 in case this one goes under. I can’t afford to be without a computer currently.
 
Any TLDR? I had my AORUS Z790 + 14900k on PL1&2 @ 253W since launch, haven't had any issues other than thermal throttle under full load benchmarks. I see on Gigabyte website BIOS F12d with "Update microcode 0x129 to address sporadic Vcore elevation behavior announced by Intel". Should I flash?

Yes, don't sweat it (can't, really)... :)

Flash it, and don't worry about anything unless you start seeing instability... then it's time to see what causes it.
 
Here is my report from trying the new microcode with 14900k. So far looks good.
Flashed BIOS 12d from Gigabyte website for my AORUS Z790 Elite DDR4.
As before, the BIOS update invalidated my Win11 PIN login. Have to be careful with this because if this happens when you don't have internet access, your windows can be permanently bricked. But with internet access I was able to log into my Microsoft account and set up a new pin.
First thing I did was set up my old RAM OC (w/o XMP). Was able to achieve 4000C16 Gear 1 without problems.
Next I tested R23, score was 37k, which is lower than what I achieved with the F10 BIOS.
Then I went into BIOS, and changed the following:
CPU Loadline Calibration -> High
IA AC Loadline -> 55
IA DC Loadline -> 55
Vcore Voltage Mode -> Adaptive
Internal CPU Vcore Offset -> -0.125V

With this configuration, I tested 30 minutes R23 loop. It rendered 93 scenes in this time period, with a score of 40699. My 280mm cooler is unable to prevent long-term thermal throttle, and temps peaked at the 90s. Single run score is 41015 with peak temps of 80s. HWInfo reports a maximum VID of 1.329V.

I will report long-term stability with this BIOS and configuration. I think the undervolt is too aggressive, but we will see.

FYI, by doing manual voltage adjustments, I’m pretty sure the voltage protection of the new micro code is disabled. So you are basically making the update pointless. You have to use the Intel default settings to actually benefit from the updated micro code.

Not exactly. I only added loadline calibration and negative voltage offset. The power and current limits are still in place. The reason my score increased is actually because of an undervolt.
 
I updated the ASUS APEX Z790 with the latest BIOS 2503 with 0x129 microcode, and I get random black screens while posting at any settings. It also crashes with RAM at settings that were stable on older BIOS versions.

Did you revert back to previous BIOS?

This has been happening to me a lot even before the BIOS update. Instead of a BIOS post screen, I would get a black screen, and the GPU LED on the motherboard would turn on, but after a minute it will show the Windows screen normally. A reboot would then result in a normal POST and the LED turns off.

Is the Intel default setting option in the bios set to performance after the modifications?
