P870DM-G GTX 1070 weird jitter...help?

[SOLVED: SEE @thegh0sts POSTS BELOW!]

Hey guys,

I have a P870DM-G, and got it into my head to do the 1070 upgrade sold by Eurocom. Ordered the card while I was out of the country, got around to it today, and...well...the photo shows all. It's like watching an old VHS on a machine where the heads were out of alignment.


I've gone through and removed the drivers in safe mode, re-seated it a few times, blew on everything with compressed air but no dice. It just...jitters like that. Additionally, the card doesn't show up in Device Manager, it just shows the standard windows display adapter. The official Nvidia driver installer can't find it either. I can get it to show up in NVFlash, and I looked up a few VBios-es to flash, but it always comes back with a device ID mismatch or some such.

I've never really seen an issue like this, and I'm kinda stumped. Anyone seen anything like this before, or have any idea what's going on?

 

Someone else had this problem. Don't remember the thread but it was an upgrade, similar to this, although I do not recall if it was the -monitor- or the videocard that was swapped out. Not going to steer you the wrong way, but I believe either an EDID, vbios or driver mod had to be done.

 

Gsync vbios causes screen corruption. Try a non gsync vbios

 

No, this is due to the 1070 not being recognised as a gsync compatible GPU to the motherboard. A non-gsync bios won't work because it has a different device ID and it will cause a mismatch. So you need to flash the gsync vbios, as counter-intuitive as it sounds but flashing a gsync vbios does work as I've faced this issue before.

This is fixable, you just need to reflash the vbios. Use the one in the link below.

I can confirm this vbios works because I am using it on my 1070 (albeit with a TDP mod but that's a different story for another post).

The problem stems from the face that the motherboard does not see the 1070 as a gsync compatible GPU as the board does not contain the device ID to allow gsync. You could try and mod the bios but nvidia wouldn't be too happy with that.

I helped another user with the same issue and my solution fixed it for them, even though it was a 1060 and the P775DM-G.

I've had this exact same problem. All that needs to be done is just reflash the vbios with the one linked here in this post.

You'll lose gsync but that's a minor thing to lose so meh.

Like I said, this is something at Eurocom doesn't tell you that this kind of stuff can happen when you buy the cards from them. it's definitely an annoyance but one that's easily fixable.

 

@thegh0sts: That vbios download link you gave worked! Needed a -6 flag in Nvflash, but w/e

I'm still having that issue where the system won't see it as a real graphics card tho...it's quite stuck on the "Microsoft Basic Display Adapter." I've removed all my old drivers with DDU in safemode and tried installing the driver through the official installer, and by "updating" it from the device manager, but no dice.

Any advice on that little lingering thread?

 

you need modded drivers since the 1070 is not exactly "compatible".

Look at page 2 of this thread.

you'll need to DDU in safe mode and restart with DSE disabled, only then can you install drivers.

 

my bad

so to confirm - since hopefully I have to do this soon - it's the other way around - eurocom ship it with non-gsync or otherwise incompatible vbios and it needs that MSI gsync one to display properly, but gsync as a function doesn't work

?

 

I don't exactly remember if the vbios that comes shipped with the MSI 1070 is a gsync or non-gsync since I overwrote it without thinking of backing up the original vbios (mainly because the glitch is too ugly to even warrant me keeping it and it was very difficult to read anything on the screen). It could have been a very early vbios since the ones from Eurocom are using 0.B boards.

One would have to assume it was a gsync vbios because I would have gotten an ID mismatch if I flashed the non-gsync vbios.

If you have prema's BIOS for the P870DM-G you can get better power limits and do the TDP mod on the 1070 and let it perform like the desktop 1070 and mod the 980DT heatsink to fit the 1070.

You will lose gsync and that's nothing you can do about it to get it back.

 

@thegh0sts Well, that did it! You, sir, are a gentleman and a scholar, and I thank you. Not just for the help, but for putting all the links in one thread. I owe you a beer, dude .

...guess we can mark this thread solved! Thank you so much again!

 

btw, you'll have to do this every single time a new driver is out...provided that j95 makes their modded INFs and you'll need those.

 

Yuck...well at least I know now. Thanks for the heads-up. Need the 1070 for VR, though, so it's #worth.

 

Have fun
