DELL G5 SE 5505 - Complete Collection Of Mods For Peak Performance & Low Temperatures

[HeyItsChris]

If anyone needs help with their Dell G5 SE 5505, let me know.

 

I'm about to get my Dell G5 SE 5505 laptop & I am going to fully unlock the hidden options in the system BIOS & the VGA AMD Radeon RX 5600M VGA BIOS as well. 

 

Mine will be the AMD Ryzen 9 4900H model with 48GB RAM & dual nvme ssd's 1tb & 500gb samsung 970 evo.

 

Not only that but I'm doing hardware mods to the system with new thermal pads & thermal paste & fixing up the fans, etc.  

 

Things I changed initially in the vbios is as follows

 

Dell G5 SE 5505 5600M BIOS Modding:
Spread Sprectrum Disabled For Higher Frequency, for PLL & DFLL (Phase Locked Lock & Digital Frequency Locked Loop) for the Core, but left Memory Spread Spectrum enabled
All i2c Temperature Sensors enabled on slave address 224, VDDC, VDDCI, SOC, PLX, MVDD
88C shutdown temperature & 84C operational limit on EVERYTHING
Overdrive set to 100% power limit, left 1800mhz peak for now in OD but with 2200Mhz peak memory slider capabilities, and all Overdrive Powerplay stuff enabled for AMD Radeon Tuning
Stock 1750mhz core peak frequency stock value/ stock 1500mhz memory value left alone for now
Fan Profile lined up to now operate at peak rpm 4,950rpm is written in the BIOS but I'll find out what it can actually do & 50C operational target temperature
Set the atom_voltage_objects_info_v4_1 (forced) & svid2 voltage controller IR35217 to -25mv programmable offset on VDDGFX & VDDC & VDDCI & MVDDC for extended thermal performance

@bonami2 Send me your vbios and ill make you a sppt if it's amd radeon?  I could also make you up a ryzenadj profile to slow global warming bro?  Let me know.  We can do this 1 step at a time, and spread the word.  I can do a lot of them, I got nothing but time.
