Hello everyone,
I have an i7 8700K system with a delidded Aorus Z370 Ultra Gaming 2.0 motherboard and Corsair Vengeance Pro 3600mhz CL 18. When I overclock the CPU to 2133 MHz with 2133 MHz RAM, it reaches a stable 5.2 GHz at 1.38V and passes stress tests and benchmarks. However, after enabling XMP, the CPU caps at 5 GHz for daily use even at 1.44V. I set VCCSA and VSSIO to 1.3V. Did I configure it incorrectly or is the motherboard unable to handle it? There seems to be a limitation from the memory controller. Note: every time I reach 5.1 GHz or higher, it crashes with a blue screen or kernel security check failure.
If you have any suggestions or settings to try, I’d really appreciate hearing them. Thanks, and sorry for my unclear English.

Of course you understand, aside from bragging, the gap between 5.0 and 5.2 is almost insignificant, especially in gaming which only affects a few frames per second. It provides a slight improvement in synthetic tests. You'd be better off using a 5ghz with a lower voltage core and enabling XMP on your memory. Yes, you're right, you might be stressing the motherboard too much on the IMC, leading to those crashes.

It mainly adds a minor increase in synthetic tests. You'd be better off using a 5ghz with a lower voltage core and enabling XMP on your memory.
