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

wonder. Dunno about Dreamcolor cable, but while I was figuring out pin outs, I learnt there are at least two ways to drive brightness control in eDP screens: using AUX channel or PWM output from board. 
I think Aetina may not have it implemented, though. It is advertised for PC boards, no ?

So you're telling me, HP cards are superior in terms of eDP? My screen is pure-eDP, 120Hz, will all the RTX Turing from HP work?

 

@nforce4maxyou also said you got an RTX Turing card to work on your M6800 with eDP with an HP card. Which version? C, D?

Did anyone have any success in getting the Pascal generation working stable?  I see the best Maxwell for the 8750W is probably 965M "A" with the standard heatsink or 980M "B" with the 8770W sink. Can the architecture run on LVDS screens anything newer?  Plan to order the 980 most likely.

Cable ready! Now waiting for spare 8570w = ) unfortunately, I had lost another auction..

(Those not connected cables aren't needed)

Yes, compact workstations only. So most probably the brightness control is not available because of that. Contacting the manufacturer wasn’t successful. If I’ll manage to repair the card (currently core is shorting during boot), then I’d look into the issue deeper. 

 

Anyway, back to the topic. Is there a possibility to get a spare laptop from abroad? Just can wait to finally see that old beast with the new screen. Good luck with the search!

Hello. I tested an RTX 3000 on my laptop and it worked. any RTX 3000 with HP/Dell bios works on eDP. So it means RTX 4000 and 5000 will work for my laptop.

 

Is the RTX 3000 HP DP_C? Correct? The 4070 from X-VISION is DP_D. I got no display from it other than external outputs.

That's seriously awesome! Would love to replicate it for 8560w, seems logical and 100% compatible.

 

Funny those old laptops are more modular than modern modular brands. Great laptops really.

 

 

Anyone tried these adapters for 2230/2242 nvme to expresscard 34? 

Kind of makes sense for hotswap storage or test system drive, hopefully not at 2.5Gbit speeds of Expresscard

I believe that is the D version.

I have and hotswap works however expect an blue screen once in a while. The performance isn't great being pcie 1x at 2.0 but still handy for moving files on/off much older laptops while serving as extra storage. The adapter itself could be better when it comes to build quality.

Has anyone got the DVD pinouts for the 5v rail for a second fan or would the current solution to run a JST "y" lead and connect into current CPU fan so both run (however how will both Tacho?) plus theres also the question on how much amps that line can take. Albeit academic when were dropping 100W+ GPU boards in......

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.

 

on the 980M card,  The photo isnt clear, what is the orientation of the 220nF (assume 16v range also) and the mosfets.  I'm ordering both just dont want to solder on upside down.  is the hot air station necesary if you have relatively fine solder point and good hands?

You leave the tacho for the main fan. The second needs three wires to run according to the main fan.

Thanks for clarifying, so it would be a 3pin JST rather than a 4 pin to replicate (red/black/yellow) to secondary fan then. Sorry for all questions, just looking to ensure i order correct part and then lose the 4th wire.

I don’t know the colors of yours, but most likely red/black/white, yellow is usually for Tach.

I got the RTX Turing to work on eDP with my laptop from 2012.

 

I still am confused about the DP_C port...

 

For example, everyone said Alienware M17X R4 eDP is DP_C. But when I tried the P5200 on it, it doesn't boot and does 8 beeps. On my Clevo it works... So my clevo isn't DP_C? Then what is it? DP_A? DP_B?

 

Both quadro cards are coming from Zbook G5/G6. Do you know what eDP port do they use?

Which CPU generation was your 2012 laptop? Just curious if the Turing Gen GPU cards are matched to certain CPU generations. Therfore assume the MXM port isnt a limitation if you can then run Maxwell (original) then Pascal & Turing. I'd love to try a Turing Card in the 8750W however the later cards i think are bigger than the 965/980M's footprint and also i think the LVDS "normal screen" will only run 980 at best.

Whether a mxm card works or not is a mixture of compatible firmware (vbios, efi etc) and hardware (traces).
DP_C stands for Display Port "channel C" sooo, if your hardware (laptop) has motherboard traces for channel C and is configured in firmware to do so, it will work with a graphics card that's also channel C DP enabled.

To get it working in M17X R4, you probably need 120Hz screen (eDP cable screen), PEG mode (bypass intel - default for 120Hz), pure UEFI (no CSM - at Maxwell and later cards) and some luck with a card (compatibility).


You can always get a ch341a @1.8v and backup the vbios prior to opening that can of worms (flashing vbios).
Mind you, it's risky and just because you flash "compatible" for your laptop vbios, doesn't mean that the vendor implemented all the traces into the GPU pcb. Also ch341a extracted vbios will be different to gpuz extracted vbios.

You don't have to go with a large MXM-B with GTX 980m or mod interface to 3.1 to have RTX 3000/5000 go fast.
NVidia made Quadro T1000 (Turning) which are MXM-A and go for about 250$ a pop.
From what sellers tell me, they require eDP, so that's a thing.

I can't find any diagrams about HP Zbook G5/G6 if they are using DP_C or I don't know which port. Not even finding my own laptop's diagram too...

Those diagrams and schematics are probably made for engineers and hide behind NDA 

 

Unless someone knows and shares, it's usually people like us who tinker and probe the traces in the darkness haha

Outside of learning how to do all the vbios VBT magic (which takes time and effort), step below is to get your hands dirty and plunge money down the drain by buying gpus, flashing them and reporting what works in what combination.

No guarantee if it will ever work, it wasn't designed to from factory. Not that this was ever an issue

Already tried that. 4070 on DP_D, other VBIOSes are bricking the card.

 

Sad I can't know what port the HP Zbook G5 G6 used because they do share the same potential port with my clevo laptop...

A lot of free time + boredoom at job = me reparing not working motherboard for parts.

Unfortunately, 40pin cable didn't worked. Not sure why, LCD may be broken or I missed something important. Fortunately, I have another cable, Im gonna try make much simpler 30pin cable. I have about 10 eDP 30pin LCDs, so we will be sure this time.

Thank you.

 

Wait a second. So my laptop is DP_D? Because the P5200 from HP worked and the RTX 3000 Turing from HP worked too on the eDP.

 

But on Alienware M17X R4 eDP the P5200/RTX 3000 didn't work, 8 beeps.

 

Very strange, why does the RTX 4070 MXM doesn't work on my laptop then? The 4070 has DP_D for eDP

If you check docs, M17X R4 (Voyager) also has DP_D on eDP.
This might sound crazy buuuuut unplug the eDP screen on M17X R4 and see if it outputs to external via HDMI and/or at least stops beeping. Maybe the screen is the issue all along.
8 Beeps in AW means more like "dont wanna" instead of "the gpu is dying of death".
Baby steps.

I tried that too back then, even if you unplug the screen and even if you plug DP, HDMI and even VGA, it still does 8 beeps.

 

Also online I saw it was DP C for eDP

Edit found something.

 

DP_A = DP/DVI?

DP_B = DP

DP_C = HDMI

DP_D = eDP

 

But why does the DP_D for eDP on the 4070 doesn't work tho? But it works for RTX 3000 Turing
