    This has been happening lately ill be playing starcraft 2 ( other games as well ) but this one specifically that all of a sudden frame rates dip to 2 - 10 fps and the game crawls. Starcraft 2 gives me a warning saying my computer is running slow. I normally get 30 - 40 fps with a mix of medium/high settings at 1920 x 1080. Temps seem normal but my cpu usage is spiked at 100% when this is happening. I know throttling on the 1645 and 1647 is common but ive never had this problem with my 1640 until now. I have 2 years left of warranty so im ok. If i call dell what am i going to tell them and what are they going to do?

    Below is a pic of temps

    W/the specs in my sig. I have throttling occur, I am currently dealing with a "Senior Support Resolver" and emailed him today that I want a laptop with the SAME specs or better(last phone call he offered me an inspiron with a low core 2 duo) and I will let you know as soon as he contacts me.

    I have been lead on too long now and told him to resolve this today, otherwise I was going to give up on him and contact Mr. Dell himself.

    EDIT: Your gpu temp is @ 84 which is just at the throttling limit(80).

    Run a ThrottleStop log file while you are gaming. Leave ThrottleStop in monitoring mode so it can monitor the performance of your computer without changing anything.

    It can help provide some hard evidence of what is going on. You can also run a GPU-Z log file at the same time since the GPU likes to under clock when it starts getting warm. ATI and Nvidia design their GPUs to run a lot hotter than 80C or 84C. Any GPU throttling is because the Dell bios has decided that you don't get to use all the performance you paid for.

    Dell doesn't seem to understand the concept that if a person buys a performance CPU and GPU that they might want to use both of them at the same time.

    To be honest i think its my cpu not my gpu. My cpu was hitting a stable 100% when it started slowing down. The cpu wasn't that hot either.

    You won't know for sure until you get some log action.....

    Keep us posted.

    It's often times power consumption and not heat that starts a throttling episode. The RGBLED looks great but also gets you closer to throttling.

    Just played for a little over and hour and i got a tiny bit of throttling.

    Here is the throttlestop log file

    Your log file looks good. A P8600 has a default multiplier of 9.0 and an Intel Dynamic Acceleration (IDA) multiplier of 9.5. When lightly loaded, one core can go to sleep while the other core speeds up by using the 9.5 multiplier. If both cores are active then the maximum multiplier is 9.0. Your log file shows that and it also shows no clock modulation going on so the CPU is performing as designed.

    You'll have to run a GPU-Z log file to confirm that your GPU is running at full speed too.
