G470 Upgrades - Need advice please.

KF4UNF_Gary

I took a Microcenter pre-build G470 and upgraded.

Current equipment:  

TUF GAMING Z690-PLUS WIFI D4 - UEFI BIOS V 1404

i9 12900KS 3.40 GHz

3090Ti

64GB DDR4 X.M.P. Enabled

Two NVMe drives, 1T and 2T for 3T total

Self contained liquid cooled with radiator. Good paste and good seating.

Monitor - Dell AW2721D

Power supply - CORSAIR RM1000X FM 80+G ATX 202

P-Core Clocks set at 5000Mhz

P-Core Sync All Cores

E-Core Clocks set at 4000Mhz

BCLK Aware Adaptive Voltage - Enabled

Actual VRM Core Voltage - Offset Mode = 1.359V

Offset Mode Sign "-"

CPU Core Voltage Offset - 0.02500

G-Sync Enabled - Current Resolution - 2560 x 1440 w Refresh rate at 240 Hz

At idle, my CPU temps are approx 25 C.

When playing any game and or testing with 3DMark my CPU temps reach between 75C and 80C 

No issues noted.

When using Cinebench to test, after about the 10th pass, I start to thermal throttle.

Again, this doesn't happen with 3DMark or any GPU or CPU based games or benchmark tools.

Can someone advise? Do I need to turn down P-Core Clocks?

I only see thermal throttle and temp only exceeds on P-Cores, E-Cores stay under.

Again, no issues noted except when running Cinebench r23

Greetings @KF4UNF_Gary,

Operating your processor outside of the default specifications can potentially damage your hardware and void you warranty.

We can provide some information. You're better off undervolting and letting TVB do the work for you. I would take a look at this article here: https://rog.asus.com/forum/showthread.php?127565-ASUS-MAXIMUS-Z690-EXTREME-amp-i9-12900K-GUIDE-Load-Lines-VF-Curves-Adaptive-Voltage

For information on TVB I would read this official documentation from Intel: https://www.intel.com/content/www/us/en/products/docs/processors/core/core-technical-resources.html

You want to undervolt and let TVB do the overclocking for you. It's easier and more efficient than manual overclocking, because it follows a voltage frequency curve rather than a static input. If you find yourself running into a thermal limitation you can consider upgrading the cooling solution. You can set TVB offsets to increase the frequency past 5.2Ghz, but even on a custom loop in that frequency range temps are almost impossible to control. Remember with Cinebench Multi-Core, it's putting an even, heavy load across all cores. That's going to create much higher temperatures than other, real world applications.
