Here are shorter patches that hopefully survive updates!
From Okrasit at Insanely (original discoverer, I'm big on giving credit where due)
http://www.insanelymac.com/forum/topic/313977-r9-nano/?p=2334590And this one for 480 based on Okrasit's work:

48 B8 04 00 00 00 01 00 00 00 48 89 43 54 C7 43 7C 12 00 00 00
Remove CU limit (didn't alter for P10):
