HP Elitebook 8570W - is it still good ? Hardware modifications

I started similar thread back on notebookreview forum, but it was closed in few months. I would very like to share some knowledge with everyone. I remember there was one person that tried same thing, but I don't remember name of thread, nor I could find it.

So..

 

For starters, my laptop is HP Elitebook 8570w. Very very long time ago I had bought 8770W, it's 17'3 inch big heavy laptop, I liked playing games on it but my back didn't like carrying it. I sold it.. and until recently, I bought 15'4 version of same laptop. But 8570w doesn't even pack a punch for older games. I though to myself, maybe buy some MSI or Alienware..

 

But..

 

I found auction of very cheap Gtx 980M, though "why not", repaired it, tried it with laptop... WORKED 😮
Then I found 8560w with Dreamcolor LCD.  Gtx didn't liked that LCD, DC screen didn't liked that GPU either. But it started working together after flashing MSI vbios (no optimus) and using 389 version of nvidia driver.
Pure UEFI and GPT is must.

 

I made some mods like upgrading VRM of GTX and custom heatsink. But I wasn't that much proud of it like I'm proud of more recent work.

 

I had bought Quadro P5200M very cheaply, it works charmingly with my HP, with only one thing not working - fan control.

But I'm on way to fix it in few weeks.  I think it have been incorrectly working programmer or not exactly fully compatible vbios.
Problem is very clearly seen in HW Monitor: motherboard i2c SMBUS sensor for GPU is stuck at 85 degrees. CPU thermal diode and GPU's correctly show exact temperature of cores. But I think there is a conflict - wrong registers or something. I'm still waiting for better chip programmer to come.

 

Specs:
Intel i-7 3740QM

Nvidia Quadro P5200M 16GB 120W

16GB DDR3L 1866 Mhz (4x4GB)

Samsung Evo 870 1TB

 

I made that HP work faster and better than his bigger brothers! Yay!

Meanwhile, let me show you some pictures. You can also ask me directly and freely, I will try to help you out!

And if you have some Quadro P5200 vbios, you can share : )

 

BTW, myths I though that are true..

1. Weak CPU limits GPUs power.   <--- Nope! When I checked with benchmarks, mine Quadro is as fast as those in original notebooks it cames from (ex. hp 17 zbook g5 or dell precision 7730). PCI Express have same speed, so.. myth busted!

2.NVMe SSD are waaaay faster <--- When I checked last time loading your game 6 seconds faster is not that much difference for everyday users. Maybe it is for ex. in movie editing.

3. No need to update dreamcolor edid for newest nvidia driver to work in 10 bit mode. I downloaded newest one and it works flawlessly.

 

To be continued..

@Mashcar I am interested in this line.

I have one of the cheapo aliexpress 980m cards and crappy vrm's has always worried me.

Can you point me in a direction of how to ID and replace the mosfets, etc . 

 

I am novice at electronics but I can do very basic micro soldering. 

Thanks :classic_biggrin:

You have to use hot air station and buy some mosfets - preferably 6 if you want to be perfectionist (I'm not sure what mosfets are used on your GTX).

 

From my older thread:

"Above two big inductors there's added 220nF capacitor, two other red circles are added 3 additional mosfets 87350D - one for every phase. "

Mosfets you can buy; capacitor you can find on practically most laptop motherboards after Core 2 Duo era (220 is written on them).  Check for correct position ofc and have fun : ) For standard 120W vBios it's more than enough - it makes VRM run more efficiently, stably and cooler.
