GTX 1070 in 5,1 Mac Pro - no 4k?

[MCMX]

I took a GTX 1070 out of an unused gaming PC and popped it into my 5,1 Mac Pro. (this card: https://us.msi.com/Graphics-card/GeForce-GTX-1070-AERO-8G-OC.html#hero-overview)

Pretty much worked great right away, I even get the Mac OS boot up screen despite not having flashed the card. FWIW I'm running most current OS and web drivers.

The problem is I am unable to get all the way up to a 4k resolution on my 4k Dell monitor. The highest available resolution is 3360x1890, and I have to choose "scaled" to get that one, by default it only wants to go to 1080p.

I have tried a Displayport -> MiniDP cable and just a standard Displayport cable, both the same result. I can run 4k on this monitor using my 2013 trash can mac pro, so I know the monitor is capable of it, it's just not working with the 1070 for some reason.

There also seems to be a slight bit of lag / jerkiness in some apps when scrolling windows (usually in my audio editing app where video is running simultaneously).

Is this just what can be expected for the pascal drivers? Or am I missing something?

If you're still within your return window send the card back and buy the Sapphire RX 580 Pulse 8GB instead.
The 1070 is horrible in macOS. I returned mine.

Hmm interesting. I didn't buy the 1070 for this purpose so need to return (was repurposed from an unused PC) but sad to see that it doesn't seem to provide any better performance than the GTX 680 I had in there. Guess I'll just go back to the older card then.

That's exactly what I did while I await the Sapphire card.

Both of the links you posted are for GTX 1060, And those are known not to work well with the MacOS. Don't know why. I know of no issue with the GTX 1070, however, Personally I am using an MVC flashed Gigabyte GTX 1080 without issue. I am very happy with the card. Both with its performance and low power draw.

They started off being about the 1060 but if you continue to read you'll see the 1070 exhibits the same issues. I'd imagine a 1080 would also, given that it would appear to be Pascal support in the web driver that is at fault.

I also have a 1080 that I use exclusively in Windows in a cMP and I agree, it's performance with low power draw is unbeatable.

Wait wait wait, no one jumped on this sentence? "Mac OS Boot Screen despite not having flashed the card"? Hmmm. Interesting.

"Boot up screen" is the exact quote, so I guess it's just a loading bar, which is normal for Sierra and it's gpu drivers that load earlier than in previous OSs.
Or is it?

 

[Fl0r!an]

Yes, he's most likely seeing the last part of the boot process, not the real deal (e.g. boot manager, single user, FileVault, OS without drivers, ...).

Regarding your 4K issue: Are you sure that macOS isn't outputting HiDPI 1080p (which is 4K with everything rendered twice as big). Native 4K is usually unavailable by default because it would be too small to read.

It's usually a good idea to install SwitchResX (or similar apps) to get all available resolutions and settings.

 

[MCMX]

oh sorry, don't know the specifics of what different/official boot screens are. I was expecting black until the login window but I ended up getting the grey apple and progress bar screens as well

I'll check out SwitchResX and see if there's any change in resolution options. Like I said on my 2013 trash can this same monitor shows a native 4K resolution so not sure why the 1070 wouldn't (esp. since it ran 3x4k monitors in the PC it came from), but I'll keep exploring. Thanks!

Did you pre-order from this?

Did you pre-order from this?

Yep, and pricing seems to have jumped up again unfortunately

I want to pre-order but it seems that no one knows exactly when these cards will begin to ship out.

Other vendors seem to hint at mid September. I'd imagine Amazon will also receive stock then.

Ahhhh! A decent wait but i'm sure it will be worth it. Going to look into this some more. I wonder about dispatch to the states. Im debating just going with another card (R9 380/X) but i'm not too sure on performance as there are not many people who run 380's in their cMP's

I believe the rather knowledgable h9826790 is the one to ask about that card! I'm pretty sure he has one.

I've reached out to him in the past. A very helpful person indeed. I believe he is also planning on getting an RX 580. If I remember correctly I believe he said that the 380 ran BruceX in 28s While i've seen reports of the RX 580 run low 20's. The RX 580 is the obvious winner but I'm torn on whether or not to wait or just buy the 380 second hand.

Hi I have a MacPro 2009, haven't flashed it make it a 2010 yet. I'm currently using a 980 GTX but I"m interested in performing the upgrade like you. Can you give me information on which card you used and how you flashed it.

 

[flowrider]

^^^^As stated in the quoted post, MVC flashed the card for me. My card is this one:

The only thing really holding me back is the fact that we don't know when the cards will arrive. It could be next month or 3 months from now. Who knows!

That's correct, 28s in BruceX.

In fact, for compute. Clearly my 7950 or 280 perform better than 380. In fact, what surprise me is that even my 7950 run at 800MHz and 380 can turbo to 990MHz, the 7950 still clearly faster in compute. I initially suspect that's driver issue. But the same result happened in Windows 10. So, I can only conclude that 380 is not that build for compute, may be more gaming orientated.

Anyway, to downvolt this card is a bit harder than 280, but just tiny bit. I can still easily make it run at ~110W under reasonable heavy load. I am sure I can make dual 380 4GB run in a cMP easily with just dual 6pin power. But the total compute power will still about 10% below dual 7950.

The advantage of the 380 is the 4GB VRAM. 3GB on the 7950 can be quite limiting nowadays. So, for 4k editing, if the VRAM usage is above 3GB but just below 4GB. Dual 380 actually can be a very powerful (but cheap) option.

I haven't done any extensive test on the graphic side yet. But I didn't expect the 380 can do much better than 7950 (if 3GB VRAM is enough).

I am sure dual 380 is more powerful then single 580 in compute. However, single 580 is much simpler in most operation, and that's real 8GB VRAM, but not 4+4 mirroring.

I expect dual 380 can finish BruceX in about 17s (estimation base on dual 7950 can finish the test in 15s). In this case, surely I will go for a single RX580 8GB.

In fact, I can get a Sapphure Nitro RX580 8GB with reasonable price now. But I decide to wait for the PULSE. I have no rush on this. Once it's price go below the MSRP $229. Most likely I will get one.

The Nitro+ has dual ROM design. In fact, I suspect it's totally possible to mod one of the ROM and make the MacOS believe it's a PULSE. But since the PULSE is a cheaper card. And I have no rush on this. I just wait until something has an attractive price to show up.

The Vega 56 seems will be a good choice as well, but unless it's clearly has good driver support. My next card will be the "semi- official" Sapphire PULSE RX580 8GB.

Hopefully when Vega widely available, the 580 price will drop.

No issues with reference 1070s, 1080s, 1080ti's, or other pascal cards here. We only briefly had trouble with the 1060, but we returned it quickly.

Single RX580 gets about 20-25s in BruceX.

The R9 3xx never had good drivers in MacOS, so I am not surprised.


The RX 580 Pulse is indeed a good choice, also because the RX VEGA 56 draws anyway too much to install it without Pixlas mod or external PSU (it's a dual 8 pin card)

Thank you again for your thorough input! I was tossing the idea around of dual 380's but didn't really now how to power it (Pixlas mod) I would like to be open to the possibility of going to higher resolutions so 8GB VRAM should work pretty good and keep me "future proof" for some time. If you are interested there is a pre-order for RX 580 Pulse on UK Amazon. Im not too sure if they ship to HK but if they do, it would be a pretty good deal. Im thinking of getting one, but don't know when the card will arrive.

That's what my assumption is as well (poor MacOS driver). However, even in Windows with the most up to date driver, still the same result. That makes me believe 380 is not decided for compute.
