看到有人提供了这个补丁，好像是解决rx480 启动的，请有卡的测一下。


So here we have the patches for use within CLOVERs config.plist:

First this one to get the two kext load into cache for CLOVER to apply patches (so you can leave original Kexts untouched):

<key>ForceKextsToLoad</key>
<array>
<string>\System\Library\Extensions\AMDRadeonX4100.kext</string>
<string>\System\Library\Extensions\AMD9500Controller.kext</string>
</array>

After this the four real KEXT-patches (paste into "KextsToPatch" section):

<dict>
<key>Comment</key>
<string>Change_#_of_RX4x0_CUs-(C)_by_okrasit_2016</string>
<key>Disabled</key>
<false/>
<key>Find</key>
<data>SLgCAAAAAQAAAEiJQ1THQ3wIAAAA</data>
<key>Name</key>
<string>AMDRadeonX4100</string>
<key>Replace</key>
<data>SLgEAAAAAQAAAEiJQ1THQ3wSAAAA</data>
</dict>
<dict>
<key>Comment</key>
<string>Remove_CU_limit_of_RX4x0-(C)_by_okrasit_2016</string>
<key>Disabled</key>
<false/>
<key>Find</key>
<data>D0LIiYuAAAAARIizmQAAAESIcyA=</data>
<key>Name</key>
<string>AMDRadeonX4100</string>
<key>Replace</key>
<data>kJCQiYuAAAAARIizmQAAAESIcyA=</data>
</dict>
<dict>
<key>Comment</key>
<string>Change_init_from_BAFFIN_to_ELLESMERE-(C)_by_Fl0r!an_2016</string>
<key>Disabled</key>
<false/>
<key>Find</key>
<data>6EmF/v++SAEAAEyJ9w==</data>
<key>Name</key>
<string>AMDRadeonX4100</string>
<key>Replace</key>
<data>6EbkAAC+SAEAAEyJ9w==</data>
</dict>
<dict>
<key>Comment</key>
<string>PP_DisablePowerContainment=1</string>
<key>Disabled</key>
<false/>
<key>InfoPlistPatch</key>
<true/>
<key>Name</key>
<string>AMD9500Controller</string>
<key>Find</key>
<string>&lt;key&gt;PP_DisablePowerContainment&lt;/key&gt;&lt;integer&gt;0&lt;/integer&gt;</string>
<key>Replace</key>
<string>&lt;key&gt;PP_DisablePowerContainment&lt;/key&gt;&lt;integer&gt;1&lt;/integer&gt;</string>
</dict>

Note: apply this one (Change_init_from_BAFFIN_to_ELLESMERE-(C)_by_Fl0r!an_2016) only, if you have RX470 or RX480, cause these card use ELLESMERE instead of BUFFIN. If you have RX460, this patch is NOT needed.

After you apply the patch for the first time, you may have to restart twice, cause info.plist patches could only be applied after the kext is in kernels cache. info.plist patches CAN'T be applied "on the fly". For more details consult CLOVER WIKI here.

After inserting the above code into your config.plist, it should look something like this:
Item 7 "Disabled = YES" cause i use Sapphire RX460 Nitro <--- which is BAFFIN not ELLESMERE - so i don't need this patch, you may switch this part to "NO" if you have RX470/RX480 gpu

期待有人测试

试了下 感觉上性能提高了点  不过也没感觉提高太多,  我用390x在mac下明显不如480性能好
