Old motherboards + new GPUs

[MagnuTron]

Alright, so I just got a sad message back from ASUS, after I had tried to use a perfectly working RX 470 on a Crosshair Formula III.

Dear ASUS Valued Customers,

Hi

Modern vga cards have bios requirements that are not met with older motherboard bioses and there are no real workarounds for this as they are designed with the w10 framework in mind. For this issue there is no solution from our side.

So I guess the whole "backward compatible" PCIe slots in kind of dead.. I know, I know, the AM3 platform is old - but we would still have though that a new card would work.

I will try a Hawaii and Maxwell GPU in it later, to see where the cutoff is regarding generations.

Poor 14 year old kid im trying to help

Hi MadsMagnus

Problem with newer cards is they might run UEFI only which ain't supported on older hardware so either see if u can get that tested in a newer computer to see if bios is UEFI only or it also support the old boot.

U can check with GPU-Z see the notch left to UEFI:

Ah right.. So modern GPUs are UEFI only huh.. That explains quite a bit. No workaround from here then right? Taking a BIOS based motherboard and throwing UEFI on it?

I have read somewhere here that some UEFI video cards have a switch that makes it use the regular BIOS. Try reading the manual of the card and see if it has (mentions) something like that?

 

[JalleR]

yes a lot of R9 390 card had the manual switch.

 

[MagnuTron]

Many of those switches were just between Uber and Quiet from what I remember. I am trying to get a hold of XFX to hear them out. Perhaps they can add BIOS support via. flash..

Most new cards only run UEFI sadly, and only work around is new hardware.

????????????????????????

There are people running RX 480 on x58 boards with no issue.

Stupid ASUS... it's why i never buy ASUS GPU's.

It's a XFX card running on ASUS mobo.

@Durvelle27 runs an ASUS X58 board with XFX 480

Which makes me question ASUS even more. They are pretty much dead-on age wise.

Check the motherboard has the latest BIOS, as UEFI support may have been added later.

Good call!

 

[Mussels]

everyone beat me to the UEFI punch, but you'd think if X58 works they'd be on BIOS :/

 

[MagnuTron]

I have flashed the motherboard to newest version, which came out in 2016. No dice.

 

[CAPSLOCKSTUCK]

@XFXSupport

might be able to offer some insight.


Edit.

if this is a known issue their packaging/advertising should highlight it.

Intel supports EFI boot since socket 775 ages... so don't mix up things.

AMD platform is the culprit really.

that WOULD explain it, AMD being behind on that one.

The RX4x0 should have a hybrid bios actually. Not only UEFI. But the AMD bios is bugged out, Intel AMI usually was much more compatible. It isn't rare that some cards simply do not start in some boards uefi or not.

UEFI GPU bios implementation looked more like a mass beta test on people really.

 

[R-T-B]

My X58 Sabertooth was a pure bios implementation, as were most X58 boards outside of intels reference boards.

There is @XFXSupport that can help.

By the way ensure to load the latest motherboard bios in before switching to a new gpu. Some board makers had beta bios for this situation

I do not have UEFI. I run my RX 480 on a legacy AWARD BIOS mainboard.

No, the X58 is a year newer. That Crosshair Formula III has the AMD 790FX/SB750 chipsets, so I am not surprised that it won't work. BTW, I do think ASUS could make it work, but there's very little incentive for them to do so.

Sorry, but he's either going to have to upgrade the motherboard or drop down to something like http://www.newegg.com/Product/SingleProductReview.aspx?reviewid=4076799

Poor kid.

Yeah exactly, ASUS doesn't seem to give a poop about this mobo anymore, and I don't really blame them. Though honestly this is one of those moments that make me question the ease of PC - or PCIe.. Because honestly ask pretty much any guy out there and we would all be like "oh no problem, PCIe is downward compatible" ... This is really fcked up.

I blame ASUS.
ASUS customer service is atrocious, and this just another example of bad or no service after the sale of products for which they charge a higher premium than their competitors.
