can't install driver rx 460

[bruderbob]

want to try an XFX RX 460 grafics card on a E8400 + Win10 32-bit configuration
I just can't seem to run the installation CD. So I run directly setup from the map win10-32 on the CD.
What ever I do, the configuration loads the default Windows driver
The AMD Autodetect finds: A-series APU
In the Bios I allready selected "Auto" (=use add-in card)
I also disabled "automaticly download manufacturers' apps and ..."
Does someone have a good idea??

Are you running the mini-tower version? Or another?

This might be the problem:
Graphic Interface PCI-Express
PCI-E Link Width x8
PCI-E Max Link Width x8

Would like it to work
Probably have to dig deeper into my pocket, to create a suitable PC for my son 🙂

The Dell has an older PCIe standard x16 slot (Intel Q45 Express chipset with Version 1.1 PCIe slot). The GPU uses a PCIe 3.0 x8 slot. Physically, the two are compatible. Trying to determine if the RX460 is going to work at all given the older tech of the Dell.

Do you know if the Dell is running the latest BIOS for its motherboard?

Isn't it the other way around ?
the Dell has a x8 slot, and the GPU uses a x16 (PCIe 3.0)

Not from what I was looking at regarding the specs for RX 460 GPUs. It doesn't matter much.

I am looking at the power limitations of your PCIe slot as the likely issue at this point. What variant of Optiplex 960 are you using?

The PCIe slot only provides up to 35w of power (this issue came up recently in another thread and I just recalled that issue). That may simply not be enough for the RX 460 to work properly and I suspect is the root of the problem.

The Optiplex 960 is the (mini) Tower version
CPU-Z: Mainboard Model 0Y958C (0x00000172 - 0x00568860)

 

[COLGeek]

I really think the power issue (only 35w to the PCIe slot) is the problem and not one you can overcome with the RX 460.

 

[bruderbob]

I can't recall, but somewhere I read the powerconsumption was <60Watt
Which is probably including the fan
The card is powered via PCIe but also a 6pin-cable
Considering the previous powersupply rating 240W, I presumed 400W would be sufficient

Differs the powersupply via PCIe in the type of PCI-slot (2.0, 3.0, ..) or in the make/modell of the motherboard ?

 

[bruderbob]

How can I determine what type of PCIe-slot or motherboard I need for the RX460 ?

 

[COLGeek]

The power supply really is not a factor here. Rather, the issue is the motherboard/slot provided power limit (<35w).

Even all of the GPUs listed in the Optiplex 960 manual draw far less than 35w from the PCIe bus.

In the other thread, even connecting external power didn't help. I haven't been able to find that thread yet.

How can I determine what type of PCIe-slot or motherboard I need for the RX460 ?

You really can't upgrade the motherboard in the Optiplex with a standard motherboard, if that is what you are thinking. You would need to install another similar Dell motherboard (form factor and connectors are the issue).

You would essentially need to build a new rig with more modern components.

Thanks guys!
It's a bommer, it's not gonna work
But at least I know what to look at now
Thanks again
