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:
-
Applied a mild overclock to the processor, setting all multipliers on the Intel Core i7 7700k to 4.5Ghz.
-
Applied an AVX offset of 1.
-
Applied a core and uncore under-volt of -125mV
-
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.
-
I also disabled power efficient P-state and power efficient Turbo boost in the BIOS.
-
Ensured that the necessary processor technologies such as VT-x, VT-d, AES-NI and SGX are enabled.
-
C-state de-and un-demotion was enabled, for C1 and C3, and the deepest C-states allowed is C8.
-
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.
-
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.
-
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.
