Anyone having Pascal driver glitches? GTX 1060 glitchy after wake-up!

[PowerMac G4 MDD]

As mentioned, the Sapphire RX 580 Pulse 8GB is the perfect card for you.
Not a variation of this card, nor different brand or model. This exact specific model is the one to get.

What if I just purchased a flashed GTX 980 4GB? It's similarly-priced when used, performs better, and works just fine in OSX. Also, since it's flashed, it will display boot screens AND have full PCIe 2.0 support under Windows (making my gaming experience better). The only downside is that it has two fewer GB of VRAM than I'd like. What are your thoughts on the GTX 980?

 

[fendersrule]

480-580 IMO are a) not good enough, and b) overpriced. It's a dumb move to buy one of these cards at this point, especially when the Vega 56 is cheaper.

Just sayin'

I'd like to learn more about these GTX 1xxx series in MacOS. Is it really this widespread?

I actually checked the Vega 56 prices, and you can only get the cards in expensive bundles right now. However, once the Vega 56 is sold by itself, it will be a better value than that 580 (assuming it's perfect under OSX).

However, I am still convinced that I should bite the bullet and just buy a flashed GTX 980. A flashed card will run at PCIe 2.0 speeds under both OSX and Windows. Also, it's a more stable platform than the 10xx series currently is [in the meantime]. It will cost more than my GTX 1060 did, but t he 1060 is more or less useless right now. It gives me issues every time I wake my machine up, and it won't run at its full potential in any OS, considering it's not [and cannot easily be] flashed.

A GTX 1080/1080Ti is probably the best 10xx choice. All others seem to have their own issues. Of course, I have no idea how flashed versions are; I'm just referring to stock PC cards. Whatever you do, do NOT get a 1060. I'm likely gonna sell mine to someone who uses a Windows PC. It's a fine card for anything other than being inside a Mac Pro and living off of cruddy Pascal drivers.

I have a 980, and I don't think it's worth it when there's new cards available and coming soon that will have native support. The Nvidia cards will glitch out, and there's no knowing if those glitches will be fixed. I've had plenty of problems. For the record, I'm buying a Vega 64 once 10.13 comes out, it'll be the best natively supported AMD card available.

Yeah, but a non-flashed Vega 64 isn't gonna be taking full advantage of PCIe 2.0. I'd get a Vega, but my reason for wanting a flashed 980 is because it would give me better performance overall than my non-flashed GTX 1060 6GB (even if the 1060's drivers didn't in-fact lack integrity) does. I'm wary of a Vega 56 card because, even if it's technically a better card, it won't be running at PCIe 2.0 speeds because it won't be flashed.
[doublepost=1502780924][/doublepost]I am curious what issues you've had with the 980 - and, is it flashed or is it not?

You're putting faaar too much weight on getting PCIe 2.0 speeds. The performance difference you get from this is negligible. Definitely not something to base a card purchase on.
I run my GTX 1080 at PCIe 1.1 in Windows and the card is a beast. It destroys any game I play, running at 1600P.

 

[William Payne]

Has anyone actually talked to nvidia tech support? They are generally pretty easy to talk to.

Odd... I've tried BeamNG.Drive with my GTX 1060 6GB - in 1080p - and it's horrible. For highest settings, a GTX 780 is recommended. IDK if it's because I have Xeons or what, but the performance isn't that hot in Windows. GTA V also doesn't play as well as it should be.

I did, but they say that bug-fixing progress is slow. They were able to replicate the issue that my card was having, but they haven't yet found out why it's happening.
[doublepost=1502783032][/doublepost]I checked benchmarks, and a 980 4GB is similar to a Radeon RX 580 8GB, and the cost is similar as well. In the end, the Vega 56 seems like a better value than either, but I'm still wondering if it will be fully compatible in classic Mac Pros. The thing about a flashed 980 is that it rules out any uncertainties. Everyone knows it works.

Remove all PCIe cards from your system and just leave the GFX card in. Update to latest NVIDIA and chipset drivers and ensure Windows 10 is up to date.
Then try Doom if you have it.

The GTX 980 is old technology now, it doesn't have HDMI 2.0 nor DisplayPort 1.4 like the new cards do, which will limit your monitor selection in future.
Definitely no 5K for example.

The only other card I have in the PCI slots is my boot SSD, which I need for OSX. Also, I am running Windows 7 - not Windows 10. On a 4,1 Mac Pro, I wouldn't be able to get back to Mac OSX without needing to do a PRAM reset.
[doublepost=1502783774][/doublepost]As for displays, I am still on 1080p, so 4K will be a big jump for me. I'm fine not having 5K. I am also concerned about the Vega's power draw... it's similar to that of the 1080Ti, and the 1080Ti has been having issues running in classic Mac Pros - it's why MacVidCards pulled it from sale until further notice.
[doublepost=1502784829][/doublepost]Can I install Windows 10 on a 4,1 flashed as a 5,1 and still expect everything to work properly?

Yep, I try and avoid cards which draw a lot of power. The GTX 1080 really is the perfect card on that front. Shame about the macOS drivers for it though!
This why I think the Sapphire RX 580 is still the perfect card for a cMP. Native drivers and reasonable power requirements. Performance is also pretty good and it is very much futureproof with DP1.4. It'll easily drive 5K screens.

Windows 10 will run perfectly on your cMP. In my experience things run far smoother than on Win7.

 

[PowerMac G4 MDD]

So... do I get the RX 580, GTX 980, or wait for the Vega 56? It's gonna be one of the three cards, and I am totally unsure.

Advantages of buying flashed 980 4GB:
*Boot screens
*Power efficient
*Around as good as my current card

Advantages of buying 580:
*Slightly cheaper than flashed 980 & similar or better in benchmarks
*Good OSX support

Advantages of Vega 56:
*Likely great OSX support, since it'll be featured in iMac Pro
*Just as much as it costs to buy a 980 or 580 and better than each of those cards
*8GB VRAM

-------

Disadvantages of 980 4GB:
*Only 4GB VRAM
*Older inputs
*Costly for what it is (esp. flashed version)

Disadvantages of RX 580:
*Costly for what it is
*High-ish power draw

Disadvantages of Vega 56:
*HIGH power draw... not sure if the classic Mac Pro will even run it with two cables



I'd like advice - I'm just torn amongst these three cards. I want compatibility in OSX and good gaming performance in Windows.

I will replace the GTX 1060 either way, but I'm gonna first try Windows 10 and see if that makes things better. Still, I am torn amongst these three cards. How do you feel about the Vega 56? Same price as 580 and way better; however, it's not out yet, and it will likely draw too much power.

 

[BillyBobBongo]

I am yet to see a retail price for the Vega 56 however, given the exorborant prices I have seen for the Vega 64, I find it very difficult to believe that there won't be some serious price gouging going on once it finally becomes available.

Yeah, that's true. Also, I am sure it will draw too much power anyway. I think I want to rule it out. This leaves it down to two options for me: either I get a flashed 980 4GB from MacVidCards, or I buy an RX 580. (Actually, I wonder if even an RX 580 would be too high-wattage...)


EDIT: peak for the RX 580 seems to be about 227-237 watts, which exceeds the 225-watt maximum for a single PCI slot & both 6-pin connectors used (if I am correct). Uh-oh...

Power draw of the Sapphire RX 580 Pulse 8GB is less than 225W as listed by Sapphire:

[pierrox]

If you really want a flashed GTX, why not go for a 980Ti?

I am worried about power draw. The 980Ti uses 250 watts at peak.

Yeah, perhaps it was some other brand that I was looking at. Still, I'd like to know how yours runs in your Mac Pro, when you receive the card. I'm wondering how things would go at the card's peak usage. (You'll likely have your card before I have ANY sort of new card.)

Also, I kinda wish this card were $250 like it said it would be; the stupid mining market is making it more near $400.
[doublepost=1502824945][/doublepost]By the way, are you able to boot back into OSX, from Windows 10, without any issues? I think this might only be for unsupported machines, but I have heard of people having issues with the Bootcamp manager in Windows 10 not allowing people to select their OSX boot driver to boot back into. A friend of mine has a 2,1 Mac Pro and must do a PRAM reset to get back into OSX. Granted, to have a 4,1 flashed to a 5,1, so maybe I won't have any issues?

Almost all graphic card will draw more than the spec at peak. In fact, it's very normal that there is some very short period shigh power draw which way above the 6pin or 8pin rating. Those rated number is for constant power draw, not the momentarily peak.

You should compare spec to spec, or actual to actual. But not spec (cMP) to actual (GPU).

In most cases, as long as the GPU spec is within the cMP limit. It will be fine. In fact, there is still zero report about a "within spec" GPU burn out a cMP yet, not even the famous RX 480.

If the actual Furmark draw shows more than 225W, then all you need to care is if the actual power draw from slot is more then 75W, or the demand from mini 6pin (each) is more than 110W (real cut off point is about 120W, but allow 10W buffer to make sure within normal error range).

Yeah, I think I will go with the RX 580 because it does allow for that ~10W buffer zone. Only problem now is that the stupid mining market has driven the prices up for a 580. I wonder if they'll go down once the Vegas are all up for sale...? Well, maybe. I mean, the RX 480's cost is also still very high. *sigh*

I personally also hope the RX580 price will go down once the Vega is widely available. RX480 still considered expensive because that's almost identical to the RX580. The 580 is more like a re-brand than upgrade. If the 480 is significantly cheaper, then everyone will rush to a 480.

Yeah, that's what I was thinking. If my NVIDIA drivers aren't fixed by that time, I'll get a 580. Otherwise, my GTX 1060 is fine, other than that single glitch it has.

 

[PowerMac G4 MDD]

Do you guys know if the Nitro edition of the Sapphire RX 580 would be okay to get - or, must it be a Pulse card?

 

[pierrox]

I know it's not related as I have a GTX 980 Ti on El Capitan, but I noticed that I'm having glitches when playing full screen video. Especially when editing in Avid Media Composer. I have two Cinema Displays connected to the GPU, one for the interface and one dedicated to full screen playback. On quick pans, or often after an edit point, the video glitches for a few frames.
My eagle eye can spot it and it's annoying.

As a test, I swapped the card with a R9 280X flashed with a Mac EFI - so it runs with the OS drivers. No glitches at all. Shame because the Nvidia is 50% faster when I render stuff with DaVinci Resolve.

Makes me wonder about the Nvidia drivers. I know they're all considered beta, but clearly it's not the best thing ever written unfortunately. That's where my post is related...
