Dell Studio 1555 overheating

Jump to solution

Hello,

I have a Dell Studio 1555 since 1.5 yrs ago.

I have a problem with overheating when I am using intensive 3D applications. This is a design problem for sure as many pple has it, even if Dell says nothing about it.

I checked that when I am using this programs the GPU voltage jumps from 0.9V iddling to 1.2V, resulting in overheating. I would like to know if there is some way to "underclock" the GPU so it will be consuming 1.1V. I think this should dramatically reduce the problem.

I will be happy to read about other solutions that dont imply changing the heat sink or opening up the laptop, as this is very hard for this model (another design problem).

Thank you.

I have already handed over his laptop in for repair. Changed the motherboard andcooling system, but the problem is not solved. With stand, you can work, but then whysuch a performance? regretted that he had bought.

My personal solution is touse intensive 3D applications with care, and monitor the temperature. I am concerned about the life of my GPU though. Also, I have a plastic base (from IKEA, around 5€) to which I drilled some holes under the "breathing" grids of the laptop. This really helped, but it is not a real solution and the thing keeps overgeating if I am not carefull. I think the best would be to hand it to some technical service to change the heatsink.

I'm having the exact same problem. I'm using HMMonitor to monitor temps and voltage, and noticed the same 0.9v to 1.2V spike. And 3D games were causing both my graphics card and motherboard to get really hot (over 90C). It got so bad the laptop would shutoff.

I had it dusted out, and put it on my laptop cooler which helped the motherboard temp a little, but it still got too hot... 75-81C. And the graphics card was still getting close to 90C.

One solution that has worked for me, is changing the power settings, such that it turns down the processing performance, before turning up the fans. Half-life 2 and Portal are a little less "smooth", but still very playable. And it's better than nothing.  The graphics card didn't go over 60C, and no voltage spike! The motherboard stayed in the 40's.

I've only tested it a bit, but so far so good.

Here is how you change the settings.  Control Panel->hardware and Sound->Power Options->'Select a Power Plan'

I selected the Dell power Plan, then 'change plan settings'. Then 'change advanced settings'.

Then scroll down to 'Processor power management', under 'system cooling policy' make sure the 'plugged in' option is set to Passive, and NOT active.

I also changed the ATI Graphics Power Settings to Maximize Power Life. NOTE: I have no idea what this does, but I thought it might help the voltage issue.

Those are the changes I made, and maybe it will work for you. I hope so. Good luck!

Спасибо hewills пробую. Думаю вся проблема в памяти она перегревается из-за того, что совмещена с видео
