Hey Everyone,
Apple dropped another bomb on us today. I have already linked to the new drivers but the problem is that there is an incompatibility. The following applies to our EFI cards, may or may not work with others or on Hackintosh. OK, BEFORE YOU RUN THE APPLE SUPPLEMENTAL UPDATE with a card that requires the Web Driver you MUST remove a particular kext. 1. Look on your main Hard Drive and find the Library folder. 2. Inside it are more folders, one labelled "Extensions" 3. Inside "Extensions" is NVDAStartupWeb.kext, drag it to the trash and empty the trash. Make sure it is out of the Extensions folder. 4. Run the Apple Supplemental Update. 5. Reboot, with an EFI card you will still have one working screen. 6. Download and install the 117 driver. 7. Post results here

Thanks again to Nvidia, they've still got our back.
See our drivers page, please post your results here. Good news is that you can use one of our flashed Kepler, Maxwell, or Pascal cards to run the High Sierra FIrmware Update. The Kepler cards will work fine in High Sierra already, with likely exception of Titan Black and 780Ti.
Initial testing with Pascal cards in High Sierra shows some changes. Anyone using The late Kepler cards mentioned above or Maxwell or Pascal cards should wait for Nvidia to release their Web Drivers. More details soon. Anyone who has done some testing should feel free to post here. So, as much as I'd like to ship off a few dozen of these babies we've been holding off due to lingering apprehension about power. I sent some cards to Barefeats.com for testing. He got FANTASTIC results, but was able to replicate my power issue.
Specifically, using any of the 3 cards (1080Ti, Pascal Titan-X and Pascal Titan-Xp) and running the CUDA-Z benchmark isn't a problem...until you hit the "Heavy Load Test" button. Then, with the Titan cards you will almost ALWAYS have an immediate shutdown. (within 2 seconds). With the 1080Ti this will sometimes require upwards of a minute, but still MOST will eventually shut down the machine. Oddly, the former "Power Virus" known as Furmark can be run for any length of time with few, if any, shutdowns. Even more perplexing is that Hardware Monitor shows LOWER numbers than with the 980Ti and Titan-X Maxwell. So the power draw must be a very fast spike, faster than the 1-2 seconds refresh for the sensors. I was hoping the issue was my aging 4,1/5,1 which has tested MANY cards. But Rob has found same behavior and posts here and at Netkas have had a few other people report the issue. In addition, one customer has reported that a 1080Ti he received will shut down the machine playing UT. He tested in other high draw situations and found the card stable. We have found a solution that was tested and confirmed working by Barefeats. A cable that connects power from a SATA drive makes the computer continue running no matter what. I have found no way to cause the power issue using this cable. Some may not like this additional cabling. Sadly, the only other choice is to stick with a 1070 or 1080 (or two) or use external power. I look forward to your thoughts and experiences. In fact, most people may never run into this issue using the Dual 6 pins inside the machine, but I need to make everyone aware of this before they buy. For the few we have already shipped (less than a dozen) we will offer either the additional power cable or a full refund (no 10% restock). We've had a LOT of interest and are just about done with testing.
Cards will be shipping on (or before) May 1. Pre-Orders start next week, please be patient. Hi, We should have cards listed later today, flash jobs coming soon after. (5/3/17) We will start with just 1070 and 1080 and perhaps a smattering of 1080Ti cards. The Titan Pascal cards will require more details. Anyone else try a new Titan-X Xp on a cMP?
Everytime I hit Heavy Lode Test Mode in CUDA-Z it shuts off my 4,1 12Core like a switch. Not a good sign. My PSU may be dying, but sure seems like this may be a bridge too far. 1080Ti good so far. So, the old trusty cMP 4,1/5,1 is getting longer in tooth as we wait for Apple to get out of their coma.
Lots of noise that it is too CPU bound for these nifty new Pascal cards. Decided to give them a workout. Ran Valley at 5K in Ultra. Check out these numbers. 1080Ti and Pascal Titan-X Xp coming soon. For more complete testing, see Barefeats. Our bestest buddies at Nvidia just sent their X-Mas present early.
Drivers for all their latest cards, now for 10.12.4. See our drivers page. We have working EFI, doing final testing and security mods before we start shipping EFI cards. Should be within a week. https://blogs.nvidia.com/blog/2017/04/06/titan-xp/
And I have seen boot screens on cMP using 1080 and first Titan-X Pascal. Obviously we need to test the EFI with actual working drivers, but we should be good to go with Mac Editions of these cards soon. It's a good time for Macs again! The trash can drought is lifting. More info soon. Hopefully you've all seen the Fireball news.
After 4 years of their "flat earth" policy, Apple has awakened ! New modular Mac Pro promised for sometime after 2017. Can only be good news. Means more and better GPUs coming again. (they'll keep selling the Dx00 cards as they pass their 6th birthday in December) This is great news for everyone interested in getting work done on a Mac. Let's hope it isn't just PR and marketing and Apple wants to be a player in Post Production again. Looking forward to the new coffee tables made of glass supported by old nMP 6,1s as they finally become truly useful. Thanks to Nvidia for keeping heat on them. You can get more work done in a 2009 cMP with a 980Ti than on a whirling dervish 6,1, largely because Nvidia kept writing drivers, even Apple said "No Thanks." So, do one last update for us Nvidia, those Pascal drivers could keep many more happy until new one appears! |
