Hi,

I have a z370 Fatality ITX board and would like to know which cache the cache ratio setting affects (L1, L2, L3)? I'm assuming L3 since the Ring/LLC Clock parameter in HWInfo matches the cache ratio setting.

Also, which voltage rail powers the L3 cache? Intel's datsheet mentions VCCIO powers the shared cache (Table 7-6, pg 123: https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/8th-gen-core-family-datasheet-vol-1.pdf) but other sources seem to indicate that the L3 cache is powered by Vcore.

Also, my "Ring to Core Ratio Offset" setting is disabled in BIOS, but the ring and core are not running at the same frequency. Is this a bug or a misunderstanding? Is the Ring ratio the same as cache ratio?

Thanks
