Let me start by asking: What is your overall goal here?
- In my own experience, you will not really get that much more real world application benefits, with that “extra 100-200 MHz”. See for instance this video for reference. Also note that the branded MSI board runs with 2666 MHz RAM speed
Instead, it becomes a lot more important to ensure that the computer is perfectly stable and will last for years to come. For reference, here is a brief overview of my overall gaming focused setup/tuning on Chinese X99 boards:
- Use a large downdraft CPU cooler for the VRM
- Do not exceed the 200A current limit. You can turn off Hyper-threading, to decrease power/current draw
- Tune the RAM heavily, a lot of performance can be extracted here
- Tune the CLR/Ring properly, at least 3.5 GHz
- There is not so much more gaming performance to be had above 4.0 GHz. Just a lot of stability issues.
To answer your questions:
- If you want to have no current limit at all (=burn your at best mediocre VRM to toast), then increase the current limit setting from 1600 (200A) to 2048 (unlimited).
- If you want to increase the multiplier above 41, then you need to change “Core Ratio limits”
- See the included file “OC changes.txt” for the locations in the BIOS
