Video ROM dump too small in my attempt at GPU passthru method

[harperhendee]

When I followed the instructions for dumping my GFX card video ROM, I ran into some issues.

I followed the instructions in the pinned thread to get GPU ROM. I get something that is about 1/10 as large as the corresponding ROM I get from the internet.  

Is this an indicator that it was unsuccessful?  

 

Is there some way to verify if a ROM is correct?

 

Do I have to dump ROM for separate pass-thru on audio portion?

 

Can I collect the ROM image from one of my other identical cards?

 

So far, I've had little luck wresting the primary MSI GTX 1070 Quicksilver from the OS.  Every time I go to activate the VM using the ROM file method, the screen will freeze and become unresponsive.  Sometimes unraid will freeze and no longer respond to pings.  Sometimes just the screen.  This happens both with official ROM and the one I manually extracted.  I do notice that when I try the unbind step, it tells me it is already unbound...

The roms I have dumped is around 50-60kb. What size is yours? 

The tech powerup versions are usually much bigger, if that is what you compare to.

The 1070 vbois is about 131kb when dumped.

Yes you can use one dumped from an identical card. I have a 1070 seahawk and a founders ed 1070. I can use the vbios from either. 

My msi seahawk and msi founders vbois are posted here. You could try one of those

I'll try some experiments this weekend.  I haven't paid much attention to it, since right now two VR rigs is all I can support.  That third GPU will be much more important as soon as I get my 3rd VR headset.
