Correct, pin 4 and 6 are actually the sense pins, but connect them to the ground is correct.

Sweet! Thanks H9. Seems all rather straight forward. I'll post the mod when I'm done as It will look rather slick. I got Black & Blue braided cord wires to match my OWC Blue SSD trays
@AndreeOnline,
I noticed your are now using the Vega FE. I was looking at benchmarks and it looks to be a good card for both FCP X and Resolve. Would you mind sharing how your are liking it so far? Would you recommend it at this point with the given graphics cards available? I just saw it on Newegg for $850.
Thanks!
Rob
Hi there. Sure.
The card has been completely stable in all of my apps. So that's good. I was hoping to see support for the card solidify in order for the fans to spin down, but that never materialised. My hope peaked as we DID get some early improvements—the card was properly recognised, but since then there has been no real improvements.
Compared to my previous card, the MSI RX480, I've doubled performance in specific scenarios—most notably in DaVinci Resolve. I've never gotten the feeling that FCPX manages to leverage this card to the max. I think FCPX relies on additional technologies to boost performance, such as QuickSync and maybe other stuff.
Occasional gaming in X-Plane also got a bump in performance in the sense that min-FPS is higher on average. In many cases meaningfully so.
Regarding my recommendation.... I now feel we need to look at things in context. My Mac Pro is mounted on its horse and riding towards the sunset as I wave goodbye from the doorway. I'm not quite sure what I intend to do with it, but a replacement is coming.
In my opinion* the sweet spot for a 4.1-5.1 Mac Pro lies between a RX480 and this Vega FE. The overall feel when working with the computer is very similar between the 480 and the Vega FE. You'll get better bang-for-buck with a 480 if you find one around $300. But if you're planning on using the FE in a Mac Pro now and then move it to an external case for use with an iMac Pro later...
Most people won't get $900 worth of performance with this card. Are you one of them?
Then again, if the gfx market is so messed up right now that you're choosing between a RX480 for $650 or a Vega FE for $850, I'd take the Vega...
*= nothing against CUDA cards. They have their own set of problems and benefits.
AndreeOnline,
Thanks so much for your thoughts! Always great to read your posts!

Hi all,
I am seriously thinking to go through the Pixlas mod. When I try to find the parts, I found this site
https://www.banggood.com/60pcs-T-Ta...&utm_campaign=pla-tool-hk-pc&cur_warehouse=CN
This looks perfect to me.
I would like to confirm that the one the I need are the 2.5-4mm^2 connectors? (In other words, I should use the BLUE connectors)
Anyway, I found this good Pixlas mod tutorial
http://thehouseofmoth.com/mac-pro-pixlas-mod/
Lots of good photos and little suggestion to make this mod easy to do.
However, when I study the 8 pin spec. I found this.
According to this, pin 4 should be connected to a 12V line. But the tutorial stated that he connected this pin to the GND line.
For me, That doesn't really matter. Because I plan to connect a 6pin cable only. I want to keep the connectors as little as possible. Either 6 or 8pin has three 12V line anyway, then I will further use my 6pin female to dual 6+2 pin to feed the card.
But I wonder how you guys connected this sense pin 1?

Hi!
Just to tell you i have finished this mod and tried it with a AMD RX VEGA 64. it works.
Now here are things that doesn't work right now (10.13.4 Mac Pro 5.1 2010 2 x5690 64Gb RAM)
HiDPI is not recognized (gpu hooked to display ACER CB281K with DP)
early boot not displaying (does it work on vega frontier? maybe a problem of support maturity?)
the thing is noisy even idling on desktop (i am interested in how the VEGA FRONTIER cope with this.
thanks

The fan noise bug is a hot topic now. I won't say that's normal, but definitely very common for Vega.
And can you elaborate more about the HiDPI issue?
This little app can help to set HiDPI resolution. You may try.
http://resxtreme.com
All the "2x" resolutions are HiDPI.
thx for all this. i’ll try tomorrow. when i say hires issue i mean no hires. display is 4k but i’d love to have 1920x1080 x2 but it does not shows up in display prefs
Usually, hold "option" key before you click "scale" in display preference should help. But I think set the resolution via this app is easier.
Anyway, I couldn't figure out Apple's standard. I've seen "HiDPI" in system preference before, but now, it's the other way around. Nothing follow means HiDPI, otherwise, will be follow by "low resolution".
But Apple did improve the system info page, now if in doubt, you can go to check what's the rendering resolution, and the "UI looks like" resolution.
Seems samsung 49 qleg gaming display seing the display ref
[doublepost=1524719856][/doublepost]I forgot an issue, sleeping issue, when putting the mac to sleep he,ll wake up every 10 min for a min, no display but fans spinning and then goes back to sleep
The info shows that you are running 1080P HiDPI now.
You can try non HiDPI 1080P, you should able to see the difference straight away
[doublepost=1524729578][/doublepost]
No, not 8k, not even 4k actually, just 3840x1080.
I use HiDPI virtual resolution to make the text looks better. Also, have better image when I zoom in, or making screen capture etc.
like i said it works and thanks, just it doesn't shows up in the monitor prefs. thanks
now i am asking myself if it's normal it is making so much noise even when idling on the desktop
i can still return the card and i am asking myself if a rx580 wouldn't be enough
The Vega Frontier and most the of Vega 64 cards generate high noise in the cMP and there is currently no solution. Get the latest info on AMD GPU Mac Pro performance in this post updated frequently by the thread starter.

are the vega 56 better? i'm tempted by a msi vega 56 air boost (wich design correspond better to the cMP gpu air flow i think)
According to some users in that thread, the Sapphire Pulse 56 and Nitro Vega 56 are the only cards working with no issues:
like i said it works and thanks, just it doesn't shows up in the monitor prefs. thanks
It does. This is the correct 1080P HiDPI resolution presentation.
I’ll try again’ when i clicked on that i switched to standard 1080p from what i remember, anyway, gonna exchange the card with a sapphire nito+ will check again once it’s there.
Do you see a chance in future of being able to flash de cards so they’ll have boot screen? Until then i found a gt 120

You screenshot clearly slows that the screen is rendering at 3840 x 2160. But UI looks like 1920 x 1080 (which means HiDPI).
IMO, practically impossible to flash any new AMD card. In fact, it's not totally impossible to flash the card to get boot screen. However, AFAIK, once flashed, the card can only shows you boot screen, and won't work properly once driver is loaded. So, no point to do so.

When you see options for 1080p, 1080i,720p in the system preferences it means Mac OS is recognising the screen as a TV rather than a monitor.
To make Mac os recognise it as a proper monitor and show all available resolutions you might try the Force RGB script here: http://www.mathewinkson.com/2013/03...ix-the-picture-quality-of-an-external-monitor

Pixlas mod done. Everything as per this guide except I only connect a 6pin to the PSU cable.
http://thehouseofmoth.com/mac-pro-pixlas-mod/
Then use a 6pin female to dual 6+2 to feed the GPU. Still the same three 12V wire inside anyway.
And the cMP now can survive under CUDA-Z heavy test.
What surprised me is that the CUDA-Z heavy test power draw is actually very low. May be the power spike causing the shutdown issue before. Anyway, that's history now.

Hi, just a question. theorically, the pixlas mod work with 1.1? (power mod for gpu)?
I am looking at a R9 390X for a 1.1, but power draw is nearing the vega64 one
