BIOS 4001

[roganaut]

Hi, 

surprisingly there's a new BIOS in town. Funny as I've just yesterday updated to 3901 Beta after long pondering. Install went on smooth. About 6 minutes, LED software and ME Update incl.  Vcore is still a bit high, here while benching. But as far I can see the spikes maybe less.  BIOS defaults. Cinebench 2024 result the same as 3901. 

Update: 13700K  ->  14900K 

My specs now: Z690-I, 14900K, 2x16 Vengeance DDR5-5600, Noctua NH-D15

As far as I can say after a week BIOS 4001 is running without issues, no spikes, as soft as butter, temps are about 35°C idle, about 60°C while GTA V. CPU is more reactive and faster than 13700K even though tamed in BIOS. I don't do heavy tasks  and don't bother my system.

My conservative BIOS Settings aiming durability:
Performance Preferences [Intel Default Settings]
Intel Default Settings [Performance]
Ai Overclock Tuner [XMP I]
XMP [DDR5-5600 36-36-36-76-1.25V-1.25V]
ASUS MultiCore Enhancement [Disabled – Enforce All limits]
SVID Behavior [Intel’s Fail Safe]
DRAM Frequency [DDR5-5600MHz]
Maximum CPU Core Temperature [80]
Long Duration Package Power Limit [125]
Short Duration Package Power Limit [125]
IA VR Voltage Limit [1350]
IA TDC Current Limit [Motherboard's Capability]

Cinebench 2024: Intel Default Settings: Extreme. Just for testing. 

After limiting IR VR Voltage to 1350 mV:

I just installed 4001 on my Z690G with a 12900k and it went fine, the voltages seemed pretty normal afterwards. No boot issues at all.

BIOS 4001 on my Z690-i + 12900KF combo fixed all previous BIOS issues i had. 3603 was the last working BIOS for overclocking for me for a long time, 3701/3802b/3901b all had the same (locked all-core clocks to 4,9Ghz) issue (Turbo ratios worked, just not all-core)

Default PCH temps are what they are (90-98*C), but with 0.96V/0.75V stay at 80-90*C. Tried 0.8v/0.7v but e-cores downclocked because of that, so undervolting the north bridge (or south bridge?) too much will lower your e-core clocks it seems. Went from 4,1Ghz under load to 3,9Ghz under load. Bumping the 1.05v to 0.96v restored e-core clocks to the expected values. This was probably the most disappointing thing about the motherboard. 500+€ for a board that cooks itself, and you have to build the entire system around that fact.

So all in all, nothing but positive to say about 4001, it is the new base line for me. But for tolerable PCH temperatures, i'm getting my next motherboard from another manufacturer.

@JohnAb - thanks for pointing me in the right direction, 4001flashed successfully. It was in fact, Windows unzip that appears to be the culprit (I unzipped it with a freshly installed WinRar as you suggested). I had been using WinZip up until I went to 24H2 and I started getting script errors so I uninstalled it assuming Windows built-in archiving tools would suffice; apparently not!

PS. I always load "Optimised Defaults" before attempting a flash and then re-instate my BIOS changes after a successful flash. Have been doing this since I owned DFI LanParty eXpert NF4-SLI board (with an AMD FX-60 CPU)... a long-time rule of thumb of mine.

Yes, I've heard of WinRar solving such problems, so glad that helped. Odd that the Windows solution can cause problems. Feedback seems positive on 4001 so far, good news 😄

I think we suspected a new version because 3901 sat on beta for longer than normal. Good to hear that some changes may have been made.

Updated no problem. Z690-G 13700K.

[roganaut]

Updated OP. Fresh install of 14900K. Counted the seconds fingers crossed what seems to last for hours. And finally B-e-e-p. Sigh.

I too updated my Z690 Extreme 12900K to 4001. Update went without a hitch and so far the system runs great on XMP II. 

[Rooke]

This looks promising.  I'll try to update to 4001 tomorrow and see what happens. ¯\_(ツ)_/¯

Yesterday I upgraded to 4001 on my Z690-F with a 12700KF, and everything seems to be working as it should.  😊

I think I spoke too soon, although I don't consider this to be much of a problem.   Today I started noticing that the CPU speed on my Z690-F/12700KF was briefly, for about 1 second, dropping down to 800MHz on all of the cores.  It only seems to be doing this when everything is idle - whether I'm overclocking or not. 

This is saving me a minuscule amount of electricity, so that's why I'm not considering this a problem. 

But it still should not be happening.

I know there's another thread on this forum regarding this situation.  This post is just a heads up for the other Z690/12th Gen. users.
