Have anyone noticed the following issue ?
I have an EVGA GTX 780 Ti SC ACX on Mavericks 10.9.5 and cannot for the life of me figure out
why the card gets down-clocked at Core 324 MHz/Memory 648 MHz immediately after
loading the desktop and stays so. As you can see from the screenshots,
when opening up "DiskUtility" or "System Information", their windows pop up minimized
with a noticeable delay of at least one second until their windows come "full-screen"
This issue has been present on all builds all the way up
Without clover device-injection, the card is reported as "GTX 780 Ti" and correct memory size,
the monitor and display resolution are correctly identified as well. Using a DVI-link card-monitor.
I have tried at least 3 nvidia driver versions so far - same situation, even with the latest driver
334.01.03f08 (used currently). I have not been using OS X for an year and a half, but I rememeer
this was the same back then at 2014's end...
What I have done so far :
- hacked NVStartup.kext to allow me to use a driver version intended for a different OS-build,
as is now the case with WebDriver-334.01.03f08 on Build 13F34. Using MacPro 6.1.
- used Clover for injecting device and EDID - with and without injection situation is the same
- hacked AppleGraphicsPowerManagement and added a respective section for the card in FakeSMC,
so on boot I get "kernel: [AGPM Controller] build GPUDict by Vendor10deDevice100a".
Judging by what Hardware Sensors says I guess this isn't working properly...
Anyone seen this on GTX 780 Ti, on the same or another vendor's card ?
Any hints will be much appreciated !
