I have a water cooled XMG Neo 17 (E23) laptop with:

I9-13900HX

32 GB (2 x 16) 6400MT/s CL38

RTX 4090

Current best TimeSpy score – 23367

CPU is undervolted

GPU is overclocked

What else can I do to improve my scores? Are there windows optimizations that will push all power to the CPU during the CPU test on the run?

I have no clue about RAM overclocking but suspect the RAM can be pushed to 7000MT/s but unsure which settings to change.

4090 is power limited to 175w and no shunt mod options for this laptop. Are there any other optimizations I'm not aware of? Is undervolting possible and likely to have much effect?

I'm not looking to game, just push my score as hard as possible. Laptop is out of warranty and willing to take some risks.

Anything else about the system that you need to know to offer advice and suggestions?

Thanks in advance.
