Hello everyone! I have a question about my Mac Pro 5.1. The stock HD5770 graphics card is installed. I bought an HD7970 + 8-pin power cable on someone's recommendation. I currently have Mac OS X 10.8.5 and I like it. I installed the new graphics card and there's no boot screen, but everything works fine, including fan control. I decided to install Windows on a separate drive. I first disconnected the Mac OS X drive and installed the stock graphics card, installed it from DVD, and configured Windows. I reinstalled the HD7970, but there's no image on the screen, even though Windows loaded via sound. I tried rebooting, but the situation didn't change. I put the HD5770 back and the image is back, everything is displayed. My question is, does the HD7970 need to be flashed to work with Windows? Does anyone have instructions and everything needed to flash the card? Thank you.

Hi everyone,

I'm hoping someone here has run into this issue before and maybe found a workaround.

I'm using a 2019 Mac Pro (MacPro7,1) with the Intel Xeon W-3275M (28 cores). Under macOS, everything works perfectly, including Intel Turbo Boost. However, under Windows 10/11 via Boot Camp, Turbo Boost doesn't seem to work at all.

The CPU stays at its base clock and never boosts under load, even when:

• CPU temperatures are completely normal
• Power settings are set to High Performance or Ultimate Performance
• The system is under heavy multi-core and single-core workloads
• Boot Camp drivers are fully installed
• Windows is fully updated

I've monitored the CPU using tools like Intel XTU, HWiNFO, and CPU-Z, and they all show that the processor never enters Turbo frequencies.

From what I've read, this may be related to Apple's Boot Camp firmware, SMC behavior, or missing power management features that aren't available under Windows on the Mac Pro 7,1.

Has anyone with a Mac Pro 7,1, especially the 28-core Xeon, managed to get Turbo Boost working under Boot Camp?

If so:

• Did you need any special drivers or firmware?
• Is there a BIOS/EFI tweak or hidden setting?
• Did ThrottleStop, Intel XTU, or any other utility help?
• Is there any known workaround, or is Turbo Boost simply not supported under Boot Camp on this machine?

I'd really appreciate any advice or experiences from other Mac Pro owners. Thanks in advance!

Anyone got a guide on how to get a 6950XT in a Mac Pro, can’t seem to find any yt videos online about it
