12900k - time spy - cpu test fluctuating

[sewerino26]

Hi pc:

12900K with NZXT KRAKEN X73

2x16GB DDR4 KINGSTON DDR4 3600MHZ in GEAR 1

RTX 3090 Ti Gigabyte Gaming

Aorus Z690 Elite DDR4 bios F5

SSD 1 TB NVM PCIE

I have Windows 11 installed the newest version.

I made 5 runs standalone of time spy cpu test. And i have 2000 points differences between run. Why? Temps are ok,other programs closed in background.
Runs:
1 : CPU Score 15 741

2 : CPU Score 15 807

3: CPU Score 17 668

4: CPU Score 15 800

5: CPU Score 17 835

i restarted 3dmark:

run 1 : CPU Score 17 747
run 2 : CPU Score 17 795
run 3 : CPU Score 17 573
run 4 : CPU Score 15 580

any ideas why sometimes its 17k and sometimes 15K?


No gsync during test.Clock 4900mhz in all runs.
