G1S-B2 CPU/RAM temps?

it seems that my CPU and RAM temps have gone way out of control the past two days, despite me not using it for anything but instant messaging and music.

According to Sisoft Sandra, the idle temps are about 78-80c for the CPU and the RAM temp is 93c. I could have sworn it was idling around 48-50c a week ago.

Is this normal? Whats going on?

 

I didn't realize that Sandra measured RAM temps, or that MB's had that capability built in. No one's ever talked about RAM temps here before, hmmmm.

In any event, your idle temps for the cpu are a touch high - have you cleaned your fan and vents lately? I'd start there and see if it helps.

 

I'll try it but I only have had the laptop for 2 weeks. My computer has been on all night sitting on a table and the top of the computer is very warm. and the bottom is almost painful to touch. CPU Temp only says 61c though. However my processor speed is only at 34%

 

Were you using the Hi/Super Performance modes in Power4Gear? These ramp your cpu up to full load speed and may not push it back down to idle, which would also explain your higher cpu temps especially if left on overnight.

Try setting P4G to email/office, and see what happens to your system temps. If they still kick up into the 80s with that setting, then your next step may be to call Asus tech support.

 

Or to have better and clearer control over the CPU, use RMClock. Don't undervolt, just control the frequencies. For a quick guide see my Tips and Tricks (signature).

It really sounds weird that the temperatures have jumped up in a space of 2 days, that's why it makes me think it's because of messed up power management.

Edit: Also have a look at the GPU power profiles... I'm not sure they can be controlled in Vista (haven't seen Vista in a while) but it's worth a try. The GPU might get hot...

 

How exactly do the Min/Max processor states have effect? On battery saving mode the temps are around 59c. On high performance they are around 80. But if I'm not stressing the CPU at all why are these temperatures so different? I set the minimum processor state on the high performance to 20%. I always figured this just lowered the clock speeds, is that not what this does?

 

That's what it should do. But Power4Gear is not very intuitive, and it is not very clear how those "20%" correspond to real CPU speeds. That's why I suggested RMClock. There, you have explicit control of the CPU speed, no ambiguity.

 

Ah, so you were using the Hi-performance P4G profiles after all.... that explains why the temps you were getting had spiked.

No, it doesn't. Hi performance turns the cpu all the way up to the max multiplier, and thus draws the max possible voltage, which generates the maximum possible heat.

Either use the correct P4G profile for what you're doing, or dump P4g and move to either the following: 1) switch to RMClock or NHC to undervolt, or 2) just use Vista's power management options which will allow the cpu multiplier to function dynamically depending on your load usage. Any of these options will keep your cpu temp in the lower ranges.

 

It still seems to get pretty hot though. The top of the laptop gets very warm, borderline hot even running at 800mhz. Is this normal as well? I just don't remember the laptop doing this. I'm buying a laptop cooler as soon as I get 30 bucks though. How can I disable P4G? Uninstall it?

I swear, whoever designed the cooling for this laptop is retarded. I took off the cover over the fan and temps went from 60c on low to 51c, and from 80c to 62c on high. Thats an 18c difference...wow...

 

1/ Is the laptop new? Could it be clogged with dust?

2/ Also did you look into the GPU power profile? (assuming you can)
I am not sure but I think that the fan is controlled on the basis of the CPU temp only, so if the GPU is in a high perf mode all the time, the heat would need to propagate to the CPU first, which would explain the abnormal heat you feel when you touch it.

(sorry if I'm talking nonsense)

3/ And yes, just uninstall power4gear and use any of the other options suggested above. I'd suggest RMClock or native Vista power management, NHC has some issues.
