MSI GX70 issues installing 5870. need help !

Hi guys, I really need some help here…

Thanks to Blacky for his support and his patience. He gave me an Alienware 5870 vcard which I installed in a MSI GX70. (don’t ask me about the original 8970…)

Without doing anything just plugged in the video card and the computer starts.
But I have some problems
- Fan speed as in full load
- Couldn’t install 5800 drivers
Should I try to flash it with a msi vbios ? Having the apu cpu with already integrated hd8650 would be any problem in flashing the 5870 bios ?

Any suggestion is appreciated
Thank you very much !

 

tried to flash the card with msi vbios... but error

 

Hello!

Yeah, I've spent all evening with his laptop. It's clear the integrated GPU doesn't play nice with the dedicated GPU.
badmyn, you need to flash in DOS mode.
Use this link to create a DOS USB Stick: FreeDOS prebuilt bootable USB flash drive image | chtaube.eu
Keep that USB Stick safe, you will it even if you get a new GPU later on.

After you create the DOS bootable USB, copy atiflash on it. Download ATIFlash 4.17 | techPowerUp
You can then use these commands to backup the BIOS and flash a new one:

I am not sure how the integrated GPU works with the dedicated one. I think all video output from the dGPU still passes through the iGPU like in Clevo notebooks. This means that you can´t just disable to iGPU from Windows devices and expected the dGPU to work properly.

badyman, these are my suggestions:
1. flash the 5870M with the MSI vBIOS, later try to disable the integrated GPU from BIOS and see if the system boots with the dGPU. If that doesn't work, talk to the person who modded your BIOS and see if you have to add the 5870M in the BIOS as an accepted GPU.
2. If this is not a BIOS/vBIOS related issue (I suspect it's not), then it can be fixed with the right drivers. I will look into driver related fixes and see if I can find anything.

If anyone else wants to help here is the deal:
He has a 5870M installed in his laptop as a dGPU and the A10 APU with the integrated GPU.
If I disable the integrated GPU the laptop won't post and we have to manually reset the BIOS.
If I leave the integrated GPU as it is,then the laptop will boot into windows, installs the drivers for the 5870M but applications don't want to switch to the 5870M, they still use the integrated GPU.
I have tried to disable the iGPU from Windows Device Manager, but this gives Code 43 on the 5870M, Windows saying that it can't use the 5870M properly. If I try to run an application in this situation, the laptop complains that there are no drivers active/installed for the 5870M.

I feel I am missing something here.

 

Well in dos.. i miss something ?

 

Yes, you need to force flash it.

Backup the original rom first.
-s name I think it's the command.

To force flash you need to add -fs , just check in the link I gave you for commands.

I've talked to Prema, he thinks changing the vBIOS to MSI might fix your problem.

 

Hi Blacky, I was a little afraid to force it... cause' I didn't want to brick the card.
Meanwhile I bought a Dell 7970m that works much better, cpu fan is ok, games ok, benchmarks not ok.

I show you some print screen in case you notice something strange please tell me.



thank you

 

All looks good. You could try and flash a MSI vBIOS to ensure maximum compatibility. It still looks like your laptop is not switching to the dGPU when benchmarking, but that could be a driver related issue.

Don't worry, you can't break the card with wrong vBIOS because you have your integrated GPU to fall-back to. You just need to backup the original vBIOS.

If you are concerned about temperatures, you can try and test with Home . They have great GPU tests, just be careful with the temperatures.

Apart from that, if you are happy with your system... try not to break it.
