Enable all cores R9 Fury cards

[kenchinito]

I came here to report that I have successfully unlock all the compute unites in my R9 Fury. Although I only get 18500 score in Luxmark. I tried doing the power mod in 9500 file but it didn't seem to make a big difference (18368 to 18540). Also, my core clock seems to be misreporting because it says 105 Mhz (1050 stock)

Any ideas on how to get 20k score in luxmark?

After looking through the whole thread--the original post says this is for R9 cards. Is this necessary to get the full potential out of R9 280X? I only saw mentions of 400 series cards.

Just want to be clear on that before I mess around with a (finally) stable config.

My Fury X uses the AMD9000Controller kext, not the 9500 kext. Here is my Luxmark Score:

So would I do the same thing to the AMD7000Controller.kext (the kext that corresponds to my R9 280X), or does this tweak not apply to this card?

I finally had some time tonight to get the fix working.

Could you try a BruceX benchie too please?

By the way, speeding up benchmarks works also on a real MacPro 3,1 with OS X Sierra 10.12.2, PowerColor Red Dragon Radeon RX480 8GB (AXRX 480 8GBD5-3DHD, Port Layout: DL-DVI-D/HDMI/DP*3. I chose this model, since it only needs one 6pin power supply.

BruceX: 33 Seconds (after editing with iHex - did not do any correct test before).

I have also installed the original Mac version ATI Radeon HD 2600, maybe that is why Unigine Heaven 4 benchmarks are the same before and after the hex editing.

This is Geekbanch before and after editing:

Hope this helps. I am planing on making a FCPX editing machine on a hackintosh. So far FCPX 10.3.1 feels way faster with my new graphics card.

It's more for the Fury cards, 300 cards, 290 cards and RX 400 series. The 280 was already supported and still is, this probably doesn't apply to the 280x.

Thanks for the heads up. Though I'm seeing some of the benchmark scores you guys are getting on OpenCL and am thinking of upping my card.

You could ask FlOr!an, who also has that card. I think it runs in a different set of drivers/kexts though.

The patch isn't necessary for any card besides Ellesmere/Polaris10 and Fiji. They have native drivers with correct configuration, so no need to patch anything.
