Interesting observations with Ryzen 5 8600G & overclocking the FCLK or Infinity Fabric Clock with 20% boost from stock & stable too on B650 chipset board. Stock cooler in use with closed up case. XMP profile for RAM in all test results.
Tests were down with Windows 11 23H2 & KB5041587 update, VBS & HVCI enabled so a vanilla OS. No fancy cutting this or stopping that going on in the software side of things with the OS.
This is the kind of overclock testing I love to do...more real world like for the average end user.
Stability test results with 3.5hrs Large FFTS in prime95;
Mem Test Pro, over 650% coverage except the last thread which is always slow in Windows 11 a scheduling issue in the OS with this program. Version 7.0 is the latest of MTP.
Now the performance increase in Memory Read is quite outstanding considering the RAM & CPU (PBO enabled) are running at XMP & AMD defaults for PBO. HVCI & VBS are enabled in Windows 11. Aida 64 will warn of this before producing results. Latest official version of Aida 64 used.
Before FCLK overclock...
2400 FCLK applied with 1.26v on SOC applied in bios. This was an educated guess on my part for stability with the FCLK despite never having OC the FCLK this high before on any AM5 cpu I have to date. But it paid off...
Nice to see a free uplift in memory read performance purely by pushing the FCLK on the 8600G. Can't complain about that!
Gigabyte have updated the bios again for this board, so see how the next step up in FCLK goes...
I sometimes wonder how gaming would go with an 8700G & its FCLK on or very near to 2500 FCLK using a dGPU & 1440p?
