Surface Pro 3 Throttling Solution?

Hearing from MS concerning this would be very helpful.

There is a great explanation of the problem here:

Cothek is correct, that is a great description of the problem. In case MS won't follow the link, I will paste text here:

"I have to share my thoughts.....

I got a launch day core i5 8gb 256GB of ram

I have noticed strange slowdowns on it when even editing basic wordpress posts... just typing letters was delayed. I would type and it would take a second for each and every letter to fill in.

My biggest issue with the core i5 is this:

A) According to microsoft it IS "designed for gaming" (see official quotes below)

Surface for gaming -Microsoft Surface 

Statements from Microsoft:

"Ready to take your game on the road? Grab a Surface Pro 3 now."

"stay on the cutting edge of games"

"Surface is an amazing tablet for playing with apps, surfing the web, or gaming."

From the Press Release:"The new, thinner fan cools a series of fins placed around it instead of forcing the exhaust air out through a channel. Not having to create space for this channel allows Surface Pro 3 to be thinner without sacrificing performance"

B)Throttling despite not exceeding heat thresholds!

Look at that screenshot, I limited the SP3 to 1.6Ghz and started a PC Game to see if It could sustain 67C and not get throttled because it never exceeded 85-90 or whatever I thought the throttling trigger limit is.

Can you see the problem?

Despite running for about 5 minutes and NEVER exceeding 67C, and sustaining a constant temperature, the device still throttled down to 60C. It is throttling ANYTHING over 60C even if not peaking above 70C!

C) The device COULD be a great gaming device if microsoft adjusted the damn throttling profile.

The SP3 throttles to 60C even after the most recent firmware which is what a lot of laptops simply idle at.

A 60C throttling temperature equates to a sustained performance speed of 1Ghz CPU, 600Mhz GPU.

I've proved that even a thermal throttle limit of even 67C would sustain a 1.6Ghz CPU 850Mhz GPU..(see Screenshot above) This is 1.6x the cpu frequency and 1.42x the GPU frequency of current SP3 throttling!

I would speculate that even a 75C thermal overhead would allow basically the full advertised performance of the device probably 2.1Ghz cpu / 1000mhz gpu, and would alleviate sustained load issues many are experiencing.

Instead, we are forced to throttle down to 60C with a 1Ghz CPU and 600Mhz GPU. You'd be better off with a AMD E Series APU for gaming with these limits imposed.. hardly a core i5 performance experience.

Microsoft NEEDS to up the throttling limit to minimum 75C, we would see massive performance gains from non-throttling in sustained workloads, these cpus are rated up to 100C and most laptop designs allow for up to 90C

If there IS some reason microsoft can't adjust the throttling profile due to design, they need to comment on it, because their official statements makes them liars about the sustained performance and the usage model they are advertising for their device.

I've returned my core i5, in hopes of a core i7, but only if microsoft can fix the throttling issues."

As stated above, GPU throttling down to 598 Mhz is killing performance and must be addressed.

If you are going to do 3D modeling, get the i7.  The i5 is real good but can 'choke' even with TurboBoost.

With the most recent update it seems that the SP3 throttles at 90C and then is limited to 70C which equates to around 2.1GHz.  Can this be raised any higher?  A higher temp will definitely achieve better sustained results.

I am considering buying the i7 version and am watching this issue closely as I plan on doing 3D modeling and graphics design as well as coding on the SP3 and will be using it at sustained load.  Even if a higher limit were an option we could enable, this would benefit many users who would like to use the SP3 as a true laptop replacement.

I notice this too especially after the July updates my games seem much slower has if the graphics or CPU power has been reduced and it was plugged in near a cooling source. I guess the battery improvements are by reducing power even during the demands.

But I just read the opposite. July's updates decreased this issue according to some tests that somebody ran in another forum.
