Hello everyone, I know in recent years this topic has come a lot (sic!), but at the current stage I'm hopeless. I'm trying to run my build at stock levels while maintaining some sort of promised performance of 13900KF. I've scoured half of the internet already, including posts here, and tested every single one of those yet without success. Regarding to RMA, unfortunately, I cannot do it, because I've got the CPU for free from a person who is not willing to go through the trouble, so this is not an option for me (but yes, I'm trying to convince them).
The issue is that with the latest BIOS and microcodes from ASUS, I got high temps and low scores in Cinebench, along with effective clocks being capped. After tweaks from part of the internet, this is my current configuration that allows me to get decent temps and scores, but the clocks/ratios still seem to be capped, and I'm not sure if the setup is correct. My overall goal is to get a stable performance within my reach. I understand it should work ok with stock settings.
Here are some details:
Bios Config (changes in comparison to defaults):
– CEP disabled
– SA CEP enabled
– Loadline calibration: 4
– AC LL: 0.32
– DL LL: auto (earlier I've set 1.02, but auto seems to work better)
– MCE: disabled (if I set to let BIOS optimize scores get higher, but so are the temps)
– SVA: typical scenario (auto seems to work better)
– Profile Intel Defaults + Extreme
– SP: 98, Cooling 160 pts.
This sets temps around 80+C in Cinebench along with ~35k result. So I've read that stock should be around that number with CEP enabled. If I enable CEP, the score gets down to < 20k and temps go to 93C… I know it's still within the limits, but my testing is done in a room where the temperature is 18C (it's a storage above the garage :D), so in a room temperature or in a hot summer it will simply throttle.
The highest score I've ever got here was 36600 pts while maintaining 93 C.
Before the microcode fixes, I was getting a max 34000 with an undervolt of -0.30mv with global offset, but that was unstable (mainly it worked but caused crashes in games and even browsers), and I still reached 100 C while getting vcore voltage around 1.5. Currently, it's steadily at 1.3-1.4 levels. The details about my setup will provide some insight into my cooling solution, etc.
Steps done so far:
– Readjusted the seating
– Tighten the screws around it
– Replaced the frame with the metal one
– Replaced the paste
– Updated bios, drivers, everything
– Tried different RAMs, different PSU, no difference
– Undervolting in BIOS <- this one gives the best results
– Tested for degradation by technician -> results said it's ok
My setup:
Mobo: ROG STRIX Z790-F GAMING WIFI
CPU: i9-13900KF, 3000 MHz, Rdzenie: 24, Procesory logiczne: 32
RAM: 7200 DDR5 Corsair CMK32GX5M2X7200C34
Memory: KINGSTON SKC3000S512G (50026B76860419F7) SSD 500GB
PSU: 1100W be-quiet platinum something
GPU: ASUS TUF RTX 3080 V2 OC LHR
COOLING: AIO Arctic Cooler Liquid Freezer III 360 + 6 fans 140mm different brands
Generally, I'm seeking guidance in making stock work ok, but if not, to improve undervolting somehow or to confirm whether it's done properly. Unfortunately, these things about OC/UV just don't stick in my head for too long.
