14900K Bios Settings

[Lude2Envy]

I recently upgraded my 12900K to a 14900K and my DDR5 Platinum 6000 to DDR5 Titanium 6400. I'm running the lasted beta BIOS with the 0x12B microcode on my Z690 Extreme. The only thing I changed in the BIOS so far is the XMP profile - have it set to XMP Tweaked. The system seems very stable, but the Cinebench R23 benchmarks are weak. Multi core is coming in at 32465 and single core is 1851. During the multi core benchmark, the P-Cores are at 4.9Ghz, E-Cores at 3.7, VCore is holding around 1.19 and the pack temp holds around 77 C. On single core, two of the P-Cores are capping at 5Ghz with the E-Cores at 3.9, VCore around 1.234 and package temp at 46 C. I've seen some different videos on undervolting while bumping the clock speeds and testing stability, but what's the current best guidance for maximizing performance without damaging the CPU. I'm also running a 360mm AIO for cooling. Thanks.

Hi @Lude2Envy since you changed the CPU and RAM on your board, did you perform a CLEAR CMOS? If you did not clear your CMOS, may I suggest you give it a try first to see what score changes do you observe. 

After CLEAR CMOS, use the Intel Extreme Profile with XMP Tweaked for your testing. If XMP Tweaked fails you can then try XMP II for stability and testing followed by going back up to XMP I and finally to XMP Tweaked testing along the way.

Sorry for the late reply. I just updated to the latest non-beta BIOS (4001). I set everything to default, then set the XMP Tweaked profile. Everything runs fine, but I'd like some more performance out of my CPU without the temps and voltage getting too high.

Which Intel Profile are you using? Performance or Extreme? Since you have 14900K, you should be using the Extreme Profile with XMP Tweaked (or XMP I or XMP II) to get this missing performance.

@Lude2Envy 

What you're seeing is a result of the Intel Defaul Profiles.

Do the following:

Set ASUS Optimised

Set Specific Performance Core Ratio Limit to 57x [for all P cores]

Set SVID Behaviour: Typical

Set ICCMAX: 400

Set PL1 and PL2 253W

Retest CR23.

out of curiosity. since asus profile automatically disables the etvb isnt it useless to set p core ratios to 57x since it defaults to 57 anyway in loads that dont go up against the power limit?

EVTB is disabled under ASUS Optimised, you're right. A force of habit on my part as I switch between both profiles [specific core carries over]. It will make no odds
