I took the time to benchmark some games with the unlocked CUs, it really made no difference at all neither negative nor positive. Tested Metal en OpenGL games/benchmarks, so I think the limitation of the CUs was only noticeable in computing performance itself. This is still a great mod for people doing GPU based 3D rendering or other GPU intensive computations.

Thank you again for the script! I was able to enable all 64 CUs on an R9 Fury X for my Mac Pro. This GPU is currently the most powerful AMD GPU for a Mac. Vega release next week may change it.

Intriguing! Were your Indigo tests with the Nano or 480? (sorry for bumping)

RX 480 likely. I retested and got 2.205 (Bedroom) and 6.809 (Supercar).

I've executed the same test several times on my early 2013 15" rMBP + Node + Sapphire 4GB RX 480. The figures are largely the same:

- 2184...2247 (Bedroom) with the same eGPU also being the current display driver (in 4k60), 

- 1628, 1628, 1629 (still Bedroom; three tests with the eGPU being NOT the current one but driving the 4k monitor from the dGPU)

- 7136...7213 in five cases and 6172 in one case (this NOT being the card non-current) (Supercar)

I've only tested the CPU once: 0.391 with Bedroom. The 650M tests weren't finished in over 30 minutes (they didn't even get to stage 1) so I stopped them (tried three times).

Incidentally, these figures are both somewhat larger than the ones (1.928, 6.261) at  https://www.indigorenderer.com/benchmark-results?page=1&sort_desc=result_bedroom&filter=highlighted . This means these are pretty impressive results and also show

- even the TB1 bandwidth poses no problems for strictly OpenCL usage,

- not even when the external display is also driven using the same card.

Hi @goalque.

I plugged in my WX5100 and tried to enable its 28 CU. Failed. LuxMark reports 14...

I started by editing the script and adding this option to it (ran it with sudo ./enable-baffin-CUs.sh ellesmere 36)

elif [[ "$second_argument" == 28 ]]

then

	CU_count="\x04\3\x0E\5"

fi

but not luck. Any suggestions?

Thanks!

I can't help with the OS X related stuff, but how about giving it a shot in a different OS? I don't know if you have Win bootcamped, but you could try to boot Linux off a live-USB stick, load the driver and run some benchmark. Just to make sure your issue is indeed in the SW config of things.

EDIT: It looks to me that the WX 5100 gets identified as a RX 460, and seems to be used as such. 14 is the number of CUs in the cut-down Baffin dies used for RX 460s.

The IT Sage referenced this script in his blog showing how install a 470/480 in my 2010Mac Pro 5,1. My question is will this script work or can it be modified for the 470 which is has 32 CUs?

Might be the dumb one in the room, but after enabling this, my Mac Pro will immediately power down whenever I try to run a Geek Bench or touch 4K footage in Premiere - was totally fine with both the above before this. Any ideas how to DISable the Baffin CU script? Or get it working?
