Tuning the Premafied Clevo P751DM2-G for maximum performance and thermals under load.

Overclocking the P751DM2-G with the Prema Mod BIOS v 1.06.09PM v2.2:

Hello guys,

A while back, Prema and I flashed the Prema Mod BIOS on the aforementioned chassis, the P751DM2-G (Branded as the Origin Eon 15-X) and I proceeded to make a few tweaks to the machine to suit my purposes:

  1. Applied a mild overclock to the processor, setting all multipliers on the Intel Core i7 7700k to 4.5Ghz.

  2. Applied an AVX offset of 1.

  3. Applied a core and uncore under-volt of -125mV

  4. Confirmed and enforced a Power Limit 1 and Power Limit 2 (PL1 and PL2) of 91W and 135W respectively. Power limit 3 was left untouched.

  5. I also disabled power efficient P-state and power efficient Turbo boost in the BIOS.

  6. Ensured that the necessary processor technologies such as VT-x, VT-d, AES-NI and SGX are enabled.

  7. C-state de-and un-demotion was enabled, for C1 and C3, and the deepest C-states allowed is C8.

  8. Thunderbolt 3 is enabled, and security mode set to Legacy as I dual boot with Linux. Until v. 4.15 is released where we can manage and authorize Thunderbolt 3 devices, this will remain unchanged.

  9. The DDI (Display Driver Interface) option is set to DP to TBT (Setting is undder Advanced Chipset Control) so that I can use MST hubs connected to the Thunderbolt docks and any other display interfaces in its' path.

  10. Flex Ratio Override is enabled and set to the highest common multiplier (45X).

A gallery of my modifications is shown here, including explanations for the options applied.

Some benchmarks are available here.
