Using 2x SATA->6pin PCIE and 2x Mini-6pin -> 8pin PCIE should be save even for most powerful GPUs. If I recall correctly, a single SATA connector is supposed to provide up to ~50W.

That might be somewhat OK for separate SATA connectors, but Apple's are two connectors on a single line, meaning the full current draw for both would come from the same line. And since PCIe 6-pin connectors are meant for 75w, not 50w, that's an additional 50w over the 100w the lines are designed for. At full load that'd be like pulling a Polaris 480 before it got the PCIe current limit fix through the lines. The PSU itself can handle it. Probably not two of these GPUs, but at least one easily. It's the lines themselves I'd be worried about. The GPU will draw whatever it draws - it's rated for that. I wouldn't want any optical drive (or anything at all really) on the same SATA line as the one I'm using to power the GPU. I sure as hell wouldn't want that kind of power surge going through the same line as any other equipment.

I guess we'll find out soon enough from Rommy whether or not it's stable for long term use.

The SATA power lines shouldn't be an issue. Not sure what Apple has used in the cMP, but SATA power wires are usually around 0.5mm^2 or 0.75mm^2, which is sufficient for 12A resp. 15A (144 ... 180W @12V).

Attaching a single PCIE 6pin to such a line (using two SATA connectors) should be perfectly fine even with additional SATA devices. The remaining 8pin can be connected by using the two onboard 6pin PCIE connectors.

There is still no report from anyone using normal CPU's. All of these Macs were upgraded to X5690's.

I think we need to ask FSP to resume production of the BoosterX5  Cheesy

These nVidia webdriver and cuda packages install fine on an 8-core 3.24 GHz cMP3.1 running 10.12.4 using DosDude's hacks currently with an AMD RX 460.  I wonder if pulling the 460 and adding a GTX 1080 would boot and produce interesting results?

Doesn't fix a JEPG issue with my Quadro 600



Seemingly al JEPG's are rendered into small colored blocks.

testing it now, it's not fixed. i might be better than it was, but still performs worse than 367. i'm still getting a noticeable amount of micro stuttering that I do not get with older driver.

No opinions?

Hi guys,

I have a nvida 1060 founders edition running the latest web driver Nvidia Web Driver - 378.05.05.05f02 - Has anybody had issue with drivers after the computers wakes from sleep? Everything is choppy and slow. A reboot seems to fix it but in the mean time I have installed back my trusty old gt120. It gives me bootscreens and is working with my 3440*1440 ultrawide monitor for basic browsing and office work. Obviously I would like to leverage the GPU for FCPX, Lightroom, Photoshop etc... But I guess the Nvidia drivers are not ready for prime time even though they finally enable the pascal cards.

Thanks for your response. I have no idea what the problem can be. I assumed that the that the reference nvidia card would have the least problems, perhaps I assumed wrong. while it was in my pc it was working perfectly. I also have an evga 1050ti in my sons pc I should try it as well to compare. Its the strangest thing!

I have the same issue with my EVGA GTX 1060 SC. I too have a feeling that the drivers just need a bit more work. Should I find a solution I'll be sure to post it here.

Edit: Interestingly I just found out that also turning my monitor (Dell Ultrasharp U3415W) off and on again fixes the issue. As is the fact we are both using ultrawide monitors.

Edit: I have also discovered that if I log out and then back in again the problem is resolved. I tried setting my system to automatically request the user to log in after sleep, but this had no effect on the problem.
