MP 1,1-5,1 Compatible RX580 8GB Brands on Mac Pro 5,1

[Snow Tiger]

I would consider to spend around $400 for a (ONE) new card. RX580 are even cheaper. You mean using a highpoint also in order to keep the NvMe cool next to the GPU?

The highpoint will allow you to have up to four M.2 SSDs installed in your Mac . Either seen as individual mountable drives or to be placed in a RAID array . It saves a lot of room to use one of these RAID cards , instead of installing them individually in an interface . The drives don't suffer from thermal throttling - I used Intel 660p and HP EX 920 drives . They also have excellent sustainable bandwidth that lasts for over a 24 hour stress test .

I have two cards. I've got next to the 970 (as a boot drive) two standard SSDs connected to another pci card. Thats fine so far I don't want to change that. I'd just like to use a bigger screen with my 5,1 so I need a newer GPU card that works next to mx 970.

With the power saving ROM selected, VEGA 56 requires less power than a RX 580. No Pixla's mod needed.

Sorry, but with power safe as performance we are at the pulse 580 levels or less?
As noise then maybe it will still be a little higher than the 580 ... no?

For a simple method of turning a cMP into a raging GPU compute demon , just drill a few holes into the side access panel , add a 1000W external PSU and snake the 8 pin PCIe power booster cables inside . Just make certain that external PSU is turned on before you boot up the Mac . This will easily push dual 300 W GPUs .

If you mod the card's I/O bracket of PCIe Slot 3 RX 480 , we could place it in PCIe Slot 4 . It would be a tight squeeze and you would lose access to two or three HDD Bays . And you'd still get four electrical lanes of PCIe Rev 2 for that card , which is OK for rendering .

The result.. IRL

AMAZING NEWS - 2.5 Width GPUs will never again interfere with SLOT 2

A picture paints a 1000 words.. First - turn your double-width bracket in to a single-slot (cost AUD 25) This image shows that almost ALL 2.5 width cards can be cleanly installed in SLOT 4 (total clearance above a standard double-slot like the RX480 pictured is 15mm) ..with that said -...

NEVER sacrifice a slot.

One way to check this is looking at ROM settings. Sapphire Pulse RX 580 Max Power is 155W + 30% PowerTune (max 201,5W), while normal non-OC VEGA 56 is 165W + 50% PowerTune (max 247,5W). With the 25% power saving setting enabled, Vega 56 is 122W + 50% PowerTune (max 183W).

People that have VEGA 56 can answer about the noise levels.

Is it "safe" to run a 970 as boot volume next to the fans of a 580?

a little less than 20w of savings compared to the 580 .... I don't understand, however, even how overall the performance is lower than the 580.

 

[bjar]

I'm curious since I don't know anyone with this card, do you have the same problems that we have with slot-2 with Sapphire Pulse?

Sorry I have not looked into the problems you mention. What exactly would you like for me to test?

Where did you obtain that single wide ( 1 " ) bracket for the GPU ? It looks like it really belongs there !

Now that I think about this , it actually was possible to install three 300 W GPUs internally in a cMP ( PCIe Slots 1 , 2 and 4 ) , although an external PSU would still need to feed the booster power connections . 900 W to power just the GPUs' booster connections is definitely asking too much from the factory PSU . Then , you could take a short 3M shielded PCIe extension cable and attach it to PCIe Slot 3 to feed say , a NVMe M.2 PCIe SSD mounted elsewhere . It would render and write project data pretty impressively , although data exporting to the rest of the world would be a shortcoming . Maybe simply removing the M.2 and treating it like a portable storage device ...

I also have the Gigabyte AORUS RX 580. Mine is MVC flashed. No clearance issues:

For anyone curious, I bought a used powercolor RX580 8gb for about 140USD, will update the forum when it comes in.

I've just added a Sapphire RX 580 PULSE (8GB, High End) with this cable: https://www.amazon.de/dp/B07GPBRWDX/ref=pe_3044161_185740101_TE_item

Runs just next to my Samsung 970 without any problems. The fans even help cooling the SSD. Runs quite. Good choice so far.

 

[t8er8]

Just installed it and its working great so far, using dual mini 6 pin molex to 8 pin, surprisingly quiet compared to my old sapphire rx560 pulse with only one fan, does make a strange humming noise from one of the fans

Thats interesting, what power cables config should be used for the 2 x 8 pin sockets (assuming the card is used with the power save selected)?

I think that the safest way is to use an eVGA Powerlink and two mini-PCie 6pin. This way you will balance the power input and keep it always inside the safety parameters of the backplane power connectors.

OK thanks tsialex. And with that powering method the vega56 is still generally a faster gpu than an RX580?

For almost all compute tasks, benchmarks show that a VEGA 56 even on lower power consumption mode is considerably faster than a Polaris 20 or 30 card. For start, it's 56 vs 36 compute units.

One thing that won't improve much, or wording better as much as the rest is improved, is hardware accelerated encoding since the VCE of VEGA is practically the same as Polaris, just faster clocks and more memory bandwidth, but no improvements with the VCE itself.

OK great thats very useful info.
Any preference on which manufacturers vega56 or are we talking any one with switchable power mode?

There are lots of users here with PowerColor Red Dragon RX Vega 56 OC and PowerColor RX Vega 56. I'm trying to find the later one on the cheap to replace my Sapphire Pulse RX 580.

I assume the Gigabyte and Msi versions are ok too?

Down here, PowerColor is the easiest one that you can find and practically all VEGAs that you can find on the used market are from them. I never saw a MSI VEGA 56.

Ah I see....here is an MSi one - https://www.msi.com/Graphics-card/Radeon-RX-Vega-56-8G

Can't help with these cards, I've been researching the models that I can find here and what my friends have and work. Seems both are reference cards, try to find reviews or images of the back of the card to see if it has the power saving switch.

 

[Pending]

Is this the switch you are referring to, as seen on this Gigabyte version?
