EFI Radeon RX 580 from MacVidCards in Mac Pro towerAugust 1st, 2019 by rob-ART morgan, mad scientistAMD GPUs are macOS Mojave 'preferred,' but without Apple's EFI*, the power up process lacks a Startup screen and support for a Boot screen. MacVidCards now offers an EFI* Radeon RX 580 and EFI* upgrade services.GRAPH LEGENDnon-EFI Radeon VII = AMD Radeon VII (16G HBM2) GPUnon-EFI Radeon RX 580 = AMD MSI Radeon RX 580 ARMOR MK (8G GDDR5) GPUEFI Radeon RX 580 = AMD Sapphire PULSE Radeon RX 580 (8G GDDR5) GPU with MacVidCards' EFI modificationEFI Radeon HD 7950 = Sapphire Radeon HD 7950 'Mac Edition' (3G GDDR5) GPUTEST MULE: 2010 Mac Pro tower with 3.33GHz 12-Core Xeon X5680 with 96GB of 1333MHz DDR3 ECC SDRAM running macOS Mojave (10.14.6). GPUs were installed in x16 slot one. The Radeon VII required supplemental power from an external power supply. (*EFI = Extensible Firmware Interface containing boot loader executables)The built-in 'Skaven' benchmark was used with the Metal based game. (HIGHER frames per second = FASTER.)The built-in three phase benchmark was used with this Metal based game. (HIGHER frames per second = FASTER.)We used the BATTLE benchmark with this new Metal game. (HIGHER frames per second = FASTER.)A single Node of Noise Reduction was applied to the Candle Project 'Parrot' clip. The effect is rendered on the fly during looping playback. (HIGHER frames per second = FASTER.)Enhance details of 12 DNG images. (LOWER Time in Seconds = FASTER.)WHAT WE LEARNEDThe MacVidCards EFI Radeon RX 580 worked as advertised. It produced the proper Startup screen complete with the Apple logo. It also invoked a Boot screen (Option key at power up) which is useful when you have multiple boot volumes. Without those 'executables,' you are flying blind. If the display fails to light up after a reasonable period of time, you are clueless as to what went wrong. With the proper EFI, the RX 580 becomes an ideal replacement for the legacy Mac Editions of the Radeon HD 7950, HD 5870, HD 5770, Quadro K5000, etc. And as you can see from the graphs, there is no performance penalty to the EFI mod. With a typical board power requirement of 185W, the 580 can run reliably using the dual 6pin factory power feeds available with the 2009 - 2012 Mac Pro tower.Always ready to push the envelope, we included the Radeon VII GPU, the current fastest AMD GPU that works with macOS Mojave. There is no Startup or Boot screen capability -- yet, but it is tempting if you are a speed freak. I expect MacVidCards is already working on an EFI upgrade for the Radeon Vega series of GPUs (RX 56, RX 64, and Frontier Edition). Just be aware that the Vegas and VII are power hungry requiring up to 300W. A secondary PSU is essential.Comments? Suggestions?

ATIccelerator II can change ATI graphics cards frequencies live, on-the-fly, under Mac OS X. It's much more sophisticated and convenient to use than Graphiccelerator for the following reasons:. no potentially dangerous flashing required. Jul 20, 2009 The overclock is not stored in the Motherboard (Logic Board) or the GPU or anything along those lines. Unlike CPU overclocking (Which can be done in software) which is usually done via the Motherboards built in Overclocking features, GPU overclocking is divided in to two camps. Note - overclocking may not work for Low speed devices which controlled by non Microsoft USB stack, like USB 3.x at Windows 7 or newest Microsoft drivers. Note 2 - you shall disable Secure Boot or modify the registry to enable loading of Microsoft unsigned drivers to successfully load driver under Windows 10 x64 version 1607 (Anniversary Update.
