I haven't figured out how to disable turbo. I can't click the box for disabling turbo. Any help?
Sorry but people here is only open to debate
to disable turbo go to power settings advance and set your CPU power state lower than 100% any value don't matter it will disable turbo
Tick Set Multiplier - Set to Turbo - Tick Disable Turbo.

Read my post.
What is the benefit in disabling Turbo?
Lower CPU temperatures during gaming and lower power consumption. This also stops my rMBP from stuttering during games.
Depending on the game my framerate is pretty much the same as having it enabled (at least in my experience)
it makes a big difference in temps playing games up to 10C lower CPU and 5C GPU and it doesn't affect frames in most of the games even open world ones
The CPU is sooo powerful that even disabling turbo the bottleneck is on the GPU
is there anything like this for osx?
Would love to see some actual numbers on this. Like cpu benchmarks and ingame benchmarks to compare, because I highly doubt there is "no" difference, but as some mentioned, it might be worth it compared to the lower power/heat.... turbo boost in general is a great thing though.
Also disable hyperthreading. Run on 4 pure cores. Better yet just disable the CPU.
I can confirm that by disabling turbo you're given far more thermal headroom for the GPU by about 10-15 degrees celsius. Considering the GPU and CPU share the same heatsink and are spaced less than two inches apart, it only makes sense that the temperature of the CPU influences GPU temperature (pretty heavily).
I've noticed that games like Just Cause 2, Bioshock (yes it's an older game), GTAIV, Crysis, SCII, ArmaII, are all pretty heavily CPU-bound games, and as such, you'll see drops in fps when you lower your multiplier in Throttlestop. However, even if left at stock values for the sake of a higher fps, the CPU's temp will rise to around 88-89C while gaming, which would raise the temp of the GPU to above the 74C mark and subsequently cause GPU throttling-related stutter. When you lock the multiplier to say, oh idk 23-25x, these same games raise the CPU temperature to only about 77-80C, again allowing for more GPU thermal headroom.
I think this throttling issue stems largely from the fact that the CPU and GPU have different Tjunctions, and likewise rise in temperature up to the Tjunction relative to the load. So if the CPU is loaded up with Crysis, it's going to start hitting the 90C mark and heating up the GPU. I've read through anecdotal evidence that the Tjunction for the 650m is much lower than the CPU, with some forum posters @ guru3d suggesting to keep Kepler cards under 80C.
You don't need throttlestop to do this just create a power profile to do this go to control panel/Power options/click on balanced and change plan settings/Change Advance power settings a little window will pop out expand processor power management and set maximum processor state to 95% hit apply and close the window now you can switch between power plans to enable-disable turbo
I don't know why people is using throttlestop if not overclocking you don't need a bunch of programs running all the time the only programs mine is running while gaming is motionjoy for my PS3 controller and Lubbos fan control to max out the fan speed
For those wanting to compare the difference between CPU turbo enabled vs disabled i have uploaded 2 pics with overlays on to show the fps and temps.
Skyrim running at 1920x1200 on ultra with no AA
Here is TB enabled:
and TB disabled:
Both were running for 15 minutes before i took the screenshot.
The fans are set to run normally on the first 2 tests (no lubbos etc)
Lastly, a screenshot with lubbos fan control running and TB disabled. (again after 15 minutes in-game):
look how cool it can be AND with minimal FPS loss.
Minimal frame loss standing still doesn't necessarily transpire to actual game play. How does it compare when action is on the screen?
Why dont you try the same thing near that Heartwood Mill? I found that due to all the vegetation, this is a very fps intensive area.
Just type into the console : coc heartwoodmillexterior
I am rather curious on how it performs there...and how the temps are there.
Personally i dont even understand why most people use Whiterun for testing, as that location isnt even fps intensive..
Here you go 1920x1200 no AA or mods
The fps are between 35-45fps with turbo disabled. ive ran around the area attacking the people and the frames remain consistant never dipping below 30
This shot is after 10 mins in-game so temperatures are about the max they get to:
That looks quite good already! I am curious, what would happen if you tried the same thing with the "The Wilds ENB" mod and 2880X1800
Would it be like 20fps then? If its not asked too much, could you try that for me?
About the temperatures, you used Fancontrol, yes?
Yes fans were controlled by lubbos. Set to max out once temp reaches 80. (Which it never does with tb disabled)
Ill install the mod and report back
