On my nMP (6 cores, D700), turbo boost works relatively well under MacOS X (from 3.5 to 3.7 GHz during Geekbench). In contrast, under Windows 8.1, CPU remains stuck at 3.5 GHz whatever the CPU load is, even when energy settings are set to the high performance mode. Do I miss something or is Bootcamp buggy?

That doesn't surprise me. Boot Camp on my nMP doesn't seem to have any of the power management features enabled whatsoever (no sleep mode, or even display sleep). I'm pretty sure Apple's drivers are half baked.

I wouldn't hold out too much hope for a fix either. I was using boot camp as the primary OS on a 15" MBP a couple of years ago and Speedstep was completely disabled (the CPU always ran at its base clock speed).

Apple's driver support for Windows has always been abysmal.

I do have sleep mode and display sleep. All of this is not very rewarding for the price...

Same here, sleep, display sleep etc all work. Check your power settings in Windows. I've had no issues with Bootcamp drivers. As for turbo boost, we should check how it normally works on PCs with these CPUs...

I would go so far to say their Windows support is deliberately spartan and minimally baked, what with crippled ATA-133 disk speeds, having to hack the MBR for AHCI, disabling sleep as it bluescreened on wake otherwise. Thankfully I use a 17 inch MBP who's monster battery gives me over 4 hours of life, but a 15 you would be lucky to get 2 hours, dreadful. Work around the faults aside they run Windows fantastic and I wouldn't be surprised they wilfully don't optimise it to keep OSX ahead for the novice bootcamp user.

Have you tried throttlestop?

I tried Throttlestop a few years ago. It made my Macbook hot enough to fry an egg when in Boot Camp.

Honestly I'm not going to worry about it too much because I have the nMP Quad so the base speed is only 200mhz shy of turbo. Also, using Intel Power Gadget in OS X, I've never seen the CPU hit 3.9ghz anyway. Apple could easily be sued for false advertising over advertising turbo speeds that are never achieved, but I'm not going to fight that battle.

I've never gone near it either, I don't game on laptops full stop and won't stress my replacement work 2011 17 inch MBP I just bought in windows till I tear it down, repaste the heatpipe with AS-5 and tint the CPU and GPU cos right now it's running 10-15 degrees c more at idle than my liking. Apple's rubbish thermal paste and over-application I have no doubt never mind the poor thermal triggers in the firmware.

Though the laptops are probably the opposite end of great thermal design compared to the nMP, plus in windows now there's a good utility in macsfancontrol that works great, can customise it to trigger fans according to different sensors etc.

I agree that turbo boost simply isn't worth worrying about for your quad, something perhaps in the future if you drop a hex or octo inside it!

Turbo boost yes, throttlestop no..nMP too expensive to risk overheating as Zinn reports...

+1 Not even with the nMP...
