Manually setting intel recommended settings for core i9 14900ks in Asus Maximus Hero Z790

[imaliasad]

Hello Support Team,

I've recently purchased intel core i9 14900ks and have been struggling with stability issues. I have upgraded the asus maximus hero bios to latest 2402 and have set everything to default. Still, i'm facing cpu heat throttling issues. I wanted to apply intel recommended settings manually but i'm struggling with finding the right parameters in the bios. 

I would appreciate if you can help me guide to set the following intel recommended parameter in the bios. Please help me, thank you.

• Enable: CEP (Current Excursion Protection - (found it)
• Enable: eTVB (Enhanced Thermal Velocity Boost) - (didn't find)
• Enable: TVB (Thermal Velocity Boost) - (found it)
• Enable: TVB Voltage Optimizations - (found it)
• Disable: ICCMAX Unlimited Bit - (didn't find)
• Set TjMAX Offset to 0 - (didn't find it)
• Enable: C-states - (didn't find it)
• ICCMAX = 249A/307A (must never exceed 400A) - (found it)
• ICCMAX_App = 200A/245A - (didn't find)
• Power Limits (PL's) - (found it)
• PL1 = 253W (recommended for best performance) - found it
• PL2 = 253W - (found it)

@Jonny0r to fix the stability issue, do the following steps. 

• Update the bios to 2301
• Set everything to load optimization default settings
• Set Performance Preference to 'ASUS advanced oc profile'
• Set Performance Core Limit to 'Sync all Core', and set All Core Ratio value to '59'
• Save Changes and Exit

Hello friend. First of all the 14900KS NEEDS the extreme profile. 320/320w and 400A.  If not it will severely downclock all the time rarely seeing that 5900 Mhz. CEP should be disabled. Also imo and many other reviewers this CPU NEEDS to be delid. Mine is delid and direct die, liquid metal and huge and powerful water-cooling solution. Also using the Intel profiles in the BIOS makes the cpu act more conservative and or downclocking etc. The downclocking are happening with quite a safe distance from ex. 253w. Apparently the system wants some head room. But FORGET 5900 Mhz on the Performance 253w profile which is made for non KS models. The 320w is for KS and even here some times there are small downclock like to 5800 Mhz..   I suggest setting PL1 and PL2 to like 320w but 511A. Even in the BIOS help text says setting this to 511 can prevent downclock and stutering. And it is simply not possilble to EVER reach 511A so there are no security risk involced. The 320w setting will always keep it back as these values are related. I had GREAT results in this with 320w safeguard and maintaining high clocks and even though that I have NEVER seen the CPU pull more than 300A in HWINFO.  But better use manual settings than the intel profiles which makes the cpu run very conservative. But 400A 320W is minimum for the 14900ks. Remember if unlimited power limits this thing draws over 400w out of the box haha.. so its totally chooked at 253w and CERTAINLY with ICC under 300A .
