Dell G5 5590 - i7-9750H Core Ratio

[Jon3s]

Hello,

I'm trying to change the CPU Ratio limit for 6 Cores.

All those settings are readable when extracting the Bios.
Its kinda too complex to understand as i can not manage to be able to interpret the Uefi Protocol.

All the things with simple Var_Offsets i could adjust so far.

What irritates me a bit is that the TDP is normally 45W, but the PL limits of up to 90W are accepted and also used without me making any other changes in the BIOS. In contrast to the GPU GTX 1650 where I cannot adjust the TDP in any way.

By completely rebuilding the heatsink I'm achieving very low temperatures and would like to allow a little more power from the GPU and if possible to get a higher ratio on the Cores.

All these statements and seemingly contradictory information about the possibilities are confusing me and so it would be great if someone could point me in the right direction please.

GPU runs with 90.17.1B.00.46 (Dell G5 5590 - i7-9750H)

*i have a CH431 Programmer at hand*

You might be able to enable some settings that are "hidden" in the bios, but it's rare to find hidden settings in bios's anymore in OEMs.

The CPU/Chipset (On die) is locked out anyways. It wouldn't matter if you put it into a board that was fully capable OC. It'll never do more than what it does now.

Best bet would be a shunt mod for the GPU and see if you can get further OC from the hardware mod. CPU you can do nothing with.

@ShrimpBrime thanks for your reply

to original goal was to get all extracted options visible back in the bios. But the settings i needed to undervolt the CPU did all work with the uefi grub mod.
So as i cant get anything else i can stop with the plan to unlock the bios with the programmer.. Would just be nice to get control over the hardware.
There are also XMP Profiles which Dell always stated are not inplemented, a bit strange. x48 x 6 cores would be a nice to have. The CPU runs really nice otherwise, way above all the other results in different benchmarks i saw.

The GPU, there i am just not really sure why its not allowed to get a higher TDP when on the other hand clock wise every adjustment is easy doable.

I just have done a small test with modifying the heatsink and i am stable at 60 - 62C at 99% workload for a long time.
It was told, to adjust the P0 State instead in the registry, but what does that really do performance wise ? I didnt see any improvement regarding TDP, still 50W.
I have done a complete Curve in Afterburner for every MHz step, but that just looks nice to run the 1650 with around 2200MHz but its nothing worth if under load it of course breaks down to about ~1850MHz.

So it would not be worth to continue with any heatsink modifications if there will be no use. Still was a funny project

I will get more info about your suggestion regarding shunt mods. Thanks for your time !
