Can't update AMD driver on Bootcamp

A suggestion, if I may, can you ask AMD for help and check with them if they will test your modified versions in their Lab?

I can certainly try, though I must admit that what I am doing here is a bit of a grey area as AMD does not officially permit modification of their drivers. I am hopeful that they will see that it is for a good cause i.e. us Bootcamp users. I will get in touch with them and see what they have to say.

OK so I thought I would provide a quick update on what you suggested, Loner T,

After contacting AMD they have said point blank refuse to support or test any modified drivers, which *****.

They are aware of issues with the M290 and M390 cards not working on any of the official drivers (or modified ones). Their engineers are working on it but they do not have a timeframe for when a fix will be issued.

As long as AMD refuse to update the bootcamp drivers alongside official PC releases then I will continue my work to provide the modified drivers.

Yes, please do. Has AMD heard of an initiative called OpenSource, but perhaps not? 😢😢

The question is are you modifying the divers or simply fooling a driver written for a different card to think it's driving the card it was intended for? Every modified driver I have tried, going back to Omega drivers and the latest Crimosn drivers, have caused my new Mac Pro with D500s to heat up drastically and fan to go into near apoplexy. The v6 Boot Camp AMD drivers written for the D500 allow them to run cool and give full access to Catalyst. GTAV runs at 2560 x 1440 at 60 f.p.s.. I can run Watch Dog 2 at that resolution at 30 f.p.s. So frankly I for one will stick with a cool Mac Pro and high frame rates rather than chase illusory gains and risk destroying my Mac. That's not to say I don't want Apple and AMD to work harder at keeping the Boot Camp drivers up to date.

I have heard of this happening for a small number of users. Using msiafterburner and downclocking the chip slightly should solve that issue (and enabling ulps though the computer wont shutdown if you do that) . I modify the drivers that amd issue so that they work on the equivalent mac cards. In the installer there is already the compatibility for the pc equivalent cards.

The performance gains are certainly not an illusion. Even on the new macbook pro with radeon pro 460 a user in my forum reports a boost of 10 fps in each game versus the standard apple driver.

Sorry, was only referring to my experience with dual GPUs on a new Mac Pro 6 core as illusory, I got no gain in f.p.s. on any game I tried and as I mentioned my Mac went into melt down mode. That said I get pretty amazing results from Boot Camp AMD v6 drivers, which I seem to recall are recognized by AMDs regular offers to update (which as we know they can't) as 15.3.

What results have you found on a new Mac Pro? I am running Windows Anniversary via an external SSD over USB3 with Boot Camp drivers installed and updated to the max.

I am driving two 27" Apple LCDs over Thunderbolt both of which are working fine in Windows 10.

I found this opencl benchmark from a single d500 running my modified drivers which you may find useful for comparison

What i do know is that the d700s work as expected without the fans going full whack constantly.

That's interesting, so no reason D500s shouldn't be fine too. Could external booting to Windows or having dual monitors be an issue?

So i think there is likely two reasons why the fans in the d500 mac pro spin up constantly.

1) the d500s are fairly underpowered even compared to d700 so to do even more basic tasks such as powering multiple displays does tax the chip more which ultimately generates more heat

2) the apple official drivers deliberately underclock all the cards to make them more heat efficient/less powerful. The modified drivers do not do this - they are clocked to standard amd specification for the card. This means, especially when disabling ulps, that it is always generating more heat due to higher clock speed which should translate into better performance but higher fan speeds too.

Good to know. Thanks.

Yes same as your question.
