ATI powerplay Q

I've got a quick question...

When I connect my DM4 with a 5450 to my external monitor via HDMI the clocks obviously jump. If the powerplay setting is at maximum battery, it's pegged at 300/300mhz (gpu/mem). If I change it to maximum performance, the minimum it runs at is 400/800mhz and it can jump all the way to 675/800mhz which is it's max. Looking at the temperature difference, there only seems to be a 1-3 C difference at most. For the long-term health of the laptop/gpu, would running it at maximum batter (300/300) be better? Or due to the little difference temperature wise, there really wouldn't be that much benefit. To be honest due to the 100/500mhz difference, I thought there would be a more significant temperature difference, but there isn't. Keep in mind that I will be running it via HDMI for a significant period of time, basically all day. Any thoughts would be appreciated. Thanks.

Oh, and I won't be gaming. Just going through slides and using Word/iTunes.

 

For the DM4, there should be no significant difference. The GPU still is well within it's thermal and power draw specs. The laptop's mobo is more likely to fail of a bad cap instead of the relatively durable silicon substrate GPU dies from TSMC (and most of the world) use.


TSMC and UMC being AMD's GPU division manuf. partner.

 

What's the thermal limit on the GPU? I know for my i5 it's 105C. Having the GPU run at 47-50C for extended periods of time is fine, right? Thanks man.

 

100C, if it follows the Desktop variant (HD5500-HD5600 series/"Redwood" core)

 

its probably 105C for max temp but 47-50C is normal running temperature... don't worry... my old Dv6's 9600M GT used to idle at 60-70C and i had to tweak it a lot to drop it till 50C..
