    I installed a 940xm last week;according to RealTemp I'm running in the mid to upper 50's at an idle. Is that to hot?

    Did you put thermal paste on it? Also depends of the ambient temperature.

    You would prefer idle temps in the 40-45C range. (Ambient temp ~72F)

    Yes I put thermal paste on it. I didn't put in on the entire surface of the cpu though only on the shiny part;it's about 1/2" by 3/4". Was I supposed to cover the entire surface; the part around the shiny surface had these little copper things on all 4 sides so I thought best not to cover them. Is it possible this cpu is too much for this pc?

    No just a drop in the middle of the die (shiny bit) should do fine. Have you checked power saver in throttlestop? Perhaps drop the TDP and TCP down a bit if you were keeping the settings that I told you when overclocking it in the other thread.

    Your ThrottleStop screen shot shows that Chipset Clock Modulation throttling is being used on your laptop and is severely hurting your CPU performance. The Chip column shows 37.5 for each thread which means your CPU is operating at less than half of its intended performance level.

    I haven't kept up on what bios version was supposed to have fixed this common M15x problem so you will have to ask other owners. The Chip column should always be showing 100.0 which shows your CPU running at its full potential and not being throttled. Do some wPrime testing and you will quickly see how a Chip setting of 37.5 kills performance.

    High GPU temps or excessive power consumption can trigger this problem.

    That is an odd looking T-Stop screenshot. What were your TDP/TDC settings at the time that SS was taken? What are/were your 5850m's temps?

    you did it correctly but i guess you idle temps are a bit too high... my idle hovers from 38-42 but I am from a cold place so may be its that....try repasting your card with "PEA" technique... you should put a pea-like drop over the shiny part and dont release the pressure on the heat-sink until you screwed down everything. :)

    Or may be it's just the curing time of the Paste you used. I would think the perfect working time for any paste would be 25-30 hours of PC usage.
