8770W abruptly shuts down under GPU load

[martin778]

So I recently got that 8770W with a 3GB GTX 970M (looks to be MSI) card someone flashed with HP BIOS.

 

Sadly, immediately after receiving the laptop I noticed it would shut down abruptly during any 3D benchmarks almost immediately also causing the connected power adapter to trip (LED goes off).

 

The notebook would then reboot but the power brick needs a power cycle to work again.

 

I only managed to finish 3DM Vantage on it while it was on battery power.

 

The CPU/RAM are fine, tested in Prime95.

There are no artifacts on screen and no warning in Windows event logs, besides a sudden power loss messages.

 

I've tried so far:

- Different motherboard, the behavior on both is identical

- Different RAM

- HP 200 and 230W power bricks

- Different driver

- Repasted the card with MX6, using K5 Pro putty on all VRAM, VRM and coils

 

I'm starting to think it might be the vBIOS that's causing some OCP to trip. I noticed that it has some crazy power limit like 1000W (others I found on TPU were also showing 1000W so maybe this is intentional?) Could anyone here take a look at it if I upload the ROM file?

let me take a quick look, I had to play with overclocking different cards.)

you can just drop the file here

That would be great, please see the ROM file attached.

Your Gtx 970 trips overcurrent protection, do you have photo of MXM board maybe ?
Or it may be just wrong vBios. I used 980 with 100w TDP for a long time in 8570w, MSI vBIOS.

[martin778]

I don't have a picture of the board, but it was a green PCB with MS-xxxx markings so most probably MSI.

 

Maybe @Maks0098 knows more.

the person above meant that maybe you even have a different BIOS flashed on your MSI card, not MSI and maybe not even some suitable HP. you should try flashing the MSI BIOS, maybe on his advice. I still haven't looked at your file, sorry, I almost forgot.)

It says "HP" in GPU-Z so it most probably has a modded BIOS. Since the 8770W doesn't have Optimus, isn't it rather risky to flash MSI vBIOS on it? I don't want to strip my M6700 to be able to reflash it and I think the BIOSes on TPU are modded already 😞 

 

Does anyone have a stock vBIOS for the 970M 3GB model?

I just looked at your BIOS and there is the required 80 watts, the BIOS is written from MSI, what you write in GPU-Z is HP, the same will happen with any card and any BIOS, the same thing is on my Alienware and Clevo, DELL and CLEVO/KAPOK respectively. you can try flashing MSI vbios from Unverified uploads on Techpowerup, maybe yours is somehow broken. but most likely you have a short somewhere, check the contact of the video card, motherboard and cooling - maybe somewhere there is something too close to some contact pad, etc. try pressing on the top of the laptop near the video card or on the bottom - maybe it will turn off, if not - have you monitored your temperature?

I will check for shorts, but no idea what could be wrong, I've already rebuilt the whole thing with a different mainboard and the result was exactly the same. It only shuts down when the GPU is under load. I also used K5 Putty for VRAM and VRM and coils so that's not that either, especially that it sometimes shuts down the moment I start any benchmark.

 

I have an HP K3000M laying around, gotta try it.

 

By the way, could it be the X bracket is somehow wrong / different?

[martin778]

That 970M is going to make a nice coaster, no idea what is wrong with it.

Currently gone back to the K3000M and everything is fine.

 

Also finally managed to score a Dreamcolor HP, but it's a 8760W, not 70. Upgraded the old 4000M Fermi to K3000M Kepler and it's dandy without modding drivers.

 

Wanted to replace the lid and the screen separately but gave up when I saw that DC has another control board screwed into the lid around the illuminated HP logo...

It also doesn't overclock even 1Hz. I bet that control board has something to do with it. Even 61Hz already causes gibberish on screen.

 

By the way, I have a trashed Zbook 17G5 I'm parting out and it has a P2000 in it. Do these also need a heatsink mod?

I think you could swap those MOSFETs on MXM boards for new ones and add those 3 missing. It should make it work. They may be unstable under higher loads, they endured up to 40A of current for long time. This should fix your GPU.

vBIOS is totally fine, you don't have to change it.

I wanted to see real photos of your mxm board to look if there is any discolour on PCB, not to know what model it is 🙂
