sager 2630qm throttling issue, CPU throttles during intelburntest @ 70C

post #1 of 2
Thread Starter 
I have a Sager 8150HM with a 2630QM 2.0-2.9 GHZ processor. the CPU never gets hot

When I run a burn test like intelburn test on multithread , the CPU runs @ 2.6 GHZ until it hits 70C, it then throttles back to 2GHZ. it then jumps back and forth between the 2 speeds keeping its temperature between 65 and 72C. other people are able to get there computers to run turbo well into the 90C range
I have downloaded throttlestop 4.0 and 5.0 and set it to turbo and turned it on , it does nothing
I am not having an issue with the processor throttling when the GPU is under 100% load during battelfield 3 gaming but thats because the cpu is just @35% during gameplay and never gets remotely hot.
I want my turbo performance that I paid for when doing heavy number crunching

I am going to re-apply thermal compound to the CPU,GPU with Tuniq TX-2 and see if that drops my temperature also gonna add some small copper heatsinks to the CPU heat spreader
but my temperatures are not even hot , I should not have to keep my cpu rinning in the 60's Celcius range on a laptop to get turbo benifit.@ 100% load
on most other stress tests, like super pie , it will hold a steady 2.5GHZ @ 100% load but that is still throttling

win 7 64 bit Ultimate
16 gb ram
6990m ATI/AMD video card
plugged in , on elevated laptop stand

I think I understand the issue. this chip is designed to do this

TM2 is the culprit

Intel has a dedicated energy consumption management unit (Power Control Unit) which monitors the temperature and energy consumption of the chip so as to modulate the Turbo accordingly. One particularity of the mobile version is that Intel allows its chips to function beyond the TDP for which they have been designed. Intel plays on the fact that the processor heats up in a relatively progressive way (you can check this yourself by launching a benchmark and monitoring the temperature via an application such as Hardware Monitor or HWiNFO). Intel takes advantage of this phase to overconsume, the goal being to exceed the TDP from the point of view of consumption (the power supply systems must be designed with this in view) but not from the ‘thermal' side. Intel thus allows processors to exceed their TDP by 25% on mobile Sandy Bridge during 28 seconds, which in practice can be relatively stressful for the cooling systems on laptops with a quad-core processor.
