Hello

Simple goal for today :
I would like to use AMD Radeon R9 390X on my 939Dual-VSTA board 😀

Main problem I can't seem to figure out is this :

Because of ^that, there are no video adapters to install drivers for :

GPU clearly works (because I can do everything in Basic VGA mode), but... it can't do anything more than that.

PCI-e 3.0 isn't the issue here as GTX 780 Ti works flawlessly on this setup :

Any ideas ?
Thank you.

I would test another Radeon PCI-E 3.0 card before dropping that theory. Or maybe motherboard just can't comprehend 8gb of VRAM.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Doesn't the R9-390X require a UEFI capable system?

I know even some of the R9-280X cards require UEFI.

I'm using EFI bootloader (Clover), to force Windows installation in UEFI mode (on GPT HDD).
Also, I thought UEFI only vBIOS woudn't even boot/POST on Legacy BIOS board ?

@The Serpent Rider OK, fair enough.
However, I don't have another Radeon PCIe 3.0 GPU...

PS. Board can handle 8GB of RAM with AM2 CPU : https://valid.x86.fr/5xzn0b
Problem still persist with it installed 😒

I got a spare Radeon R9 290 (same GPU as the R9 390X) and a 939Dual-SATA2 with an AM2 CPU which I can try together under Windows 7 if you want me to. Just have to swap out the crappy 300W PSU in that rig.

@MrMateczko Well, there are only 3 BIOS'es for this board (aside from First release), and unofficial one (1.30A) adds... better Fan control.
I don't think there is a BIOS that can help me 🙁
Unless... someone could mod AMD PCI-e 3.0 support into official one 😉

@Kamerat
If you could, please do. I would like to know if it's something that can be bypassed on other AMD PCI-e 3.0 GPU.
BTW, I tested my other AM2 board :
AliveDual-eSATA2, and it doesn't even show post with this card 😒
However, based on sounds, it does try to boot... there simply is no picture on monitor and it fails in loading Windows (crash and restart on booting, from what I can hear).

On my Rampage Extreme (X48, LGA 775) - card works fine (so, it can't be UEFI only card) : LINK

Most likely this is some kind of incompatibility with the ULI chipset. Unfortunately I don't have this board to test it myself, the oldest chipset I was using with Hawaii card is nForce Pro 3600 http://hwbot.org/submission/3699921_havli_pcm … 380_18022_marks

It works. Installed a XFX R9 290 (reference design) on a 939Dual-SATA2 today and drivers intalled just fine in Windows 7 64 bit. Not running any EFI bootloader BTW. Also tried a couple of games which also works. The board is stuffed with 6GB DDR2 memory.

Looks like 8gb is just too much.

Indeed 🙁
@Kamerat Can I ask for a 3DMark Firestrike run screen shot or a valid link (would like to know if it's stable and how far in score it can go on Athlon64 S939 platform) ?
Thank you very much for your help.

Wish someone had a OG GTX Titan or GTX 980 Ti with 6GB VRAM to see if they can work in this board...

Half-year update on this (it took a while to get a 4GB+ VRAM card to test this 😁)
We were wrong. The board works with 8GB VRAM cards (Memory Hole option enabled), it simply defaults to 16 color (that's NOT "16-bit" mind you), palette without drivers.

I tested GTX 1080 with mine :

It must be shocking to see Windows 7 in 16 colors (I assume that's what you were running judging by the screenshot above). 😵

Anyways, glad to hear you got your GTX 1080 to work with your 939Dual-VSTA motherboard, that graphics card has twice the memory as your RAM.

Yes, I know, I was talking about what it must've been like before having the drivers installed. Sorry for not being clear enough.

Final update : Memory Hole = [Enabled] to the rescue !

EDIT :
So, after a card replace, 390X stopped working... again.
I can say this issue is NOT PCI-e 3.0 based and is limited to 3GB VRAM or more.
Kepler GPUs are working "out of the box", while Pascal and 390X do not 😒
They MAY work if windows was installed on them.
