Thank hyppo you are the one ...

Download hwinfo 64 look at the tab for the gpu monitor this meanwhile you are benchmarking iam pulling 91W @1800 MHz !!!

good
you can start disassemble and remove motherboard meanwhile, I also think you can keep cooling system and remove mobo and cooling together just remove fans and unscrew one screw from cooling

This is why I don’t like software method of bios unlocking
Yesterday I was playing tuning latencies and after some changes in bios laptop was bricked, nothing helped, pressing power for 12 sec, remove batteries, memory, nothing
After powering on keyboard light up, fans spinned and stopped, screen is black, and it gets hell hot
Imagine if I would not have real hardware dump, what could I do?

Bit fortunately I had my dump and trusty CH341A programmer, I flashed a dump and now it’s alive)

I’m pretty sure it was a menu ICC/OC menu and parameter ICC/OC spread value, value (47% by default)
Now I know that with some changes in bios (not related to gpu), laptop can be bricked

Hi,

I have dead Bios chip on my Helios 300 ph315-52.

I already have new chip w25q80 soldered on motherboard but now I need dump to program it via ch341.

Can someone post dump?

thanks

@zmay2509 hey w25q80 is not a bios
the bios chip is on opposite side of the motherboard, I explained in the beginning of the thread
anyway I have a dump from both chips

Hi Hyppo,

Can you send me link with BIOS back up?
And can I know your set up is it 9750 and 2060?

Thanks for pointing out that BIOS chip is under!

I have both dumps with 9750H+1660ti and 9750H+2060
This one is with 2060

Thanks Hyppo!!

Great news I finally have working laptop again :)

Now I have problem with serial number and everything that dump replaced Mac addres...

I have insyde EZE tool can I do it with that?

Is it a easy fix?

Thanks again

@zmay2509
Great news)
I wonder how you managed to brick it?
And yes I would like you replace my personal data but I really have no idea how to do it, all I can do is only unlock))
I think only @Lost_N_BIOS can help
And btw you can flash bios from windows now using fptw

I broke it becouse I didn't have clip for ch341 so I desolder it from board and solder it in wrong way on breakout board I just see white smoke.

@Lost_N_BIOS can you help me with changing data on BIOS?

Thank

Desolder! This is the most hardcore method)
So now you are the 4th in the world with the unlocked bios
Our bios has flash protector disabled so it’s possible to flash in windows using fptw utility, it was discussed earlier in this thread

@Valantur
I don't know why you need unlocked bios)) Only if you want to set custom frequency and timings at memory. Or maybe to set numlock to ON on the boot)
All other useful settings will be overwritten by EC
Increase PL to 56W, undervolt more or control fans you can do all that without unlocking

How can I increase the PL to 56W without turning on Turbo Mode and turning my laptop into an airplane taking off (in terms of noise)? I'm not running Predator Sense (don't even have it installed), and I'm relying on Throttlestop to get as much performance as I can from this laptop. I seem to hit the 45W PL after just 30 seconds or so (when doing a performance test, gaming doesn't seem to hit the 45W limit that early).

I'm already undervolting.

Your insight is appreciated!
Thanks!
