AMD Windows Drivers now enable ECC on 2013 Mac Pro

[N19h7m4r3]

With the update to drivers to 14.9, with the new Fire Pro Control centre, the 2013 Mac Pro Graphics card have all FirePro option.

ECC which can be toggled on and off, Quad Buffer, and 10-bit pixel format support.

Strangely GPU-Z now sees the cards as 7900 series instead of FireGL V.

It also says your memory is 150MHz next to default clock.

Yup, it does for one of the cards. It's downclocked for power saving it seems.
Even disabling ULPS the power saving feature doesn't change that read out, either way it doesn't affect performance at least.

I'm really hoping we'll get some updated drivers that actually properly identify the D*00 series cards and assigns the correct memory and core clocks.

Does anyone know if these settings still work in Windows using the current drivers?

On AMD's website for the 'Radeon Pro Graphics Tools and Settings' it says "ECC memory support available on AMD FirePro™ W8100, W9100 and AMD Radeon™ Pro WX 8200, 9100, SSG, and VII graphics cards."

I still don’t know if ECC support is selectable in Windows with the current drivers, but digging into this a little more it appears both the D500 and D700 have ECC memory.

For example, this Tech Report page says, “All of Tahiti’s SRAMs are single-error correct, double-error detect protected.”

And on this forum someone posted, "Tahiti does support ECC on its GDDR5 memory via a RAID5 like algorithm. This reduces the available memory from 6 GB to 5.25 GB. To date, the D500 and D700 cards in the Mac Pro do not have the option to enable this." So they support it as long as you can select it on the software side.
