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.
