Throttling CPU and GPU Problems on 1558

Hi,

I've been having some throttling issues with my 1558 for a past few days. I've been using it in the us but i'm on vacation now n i'm working on a 220V supply! Does that affect the performance of the adapter in any way?

My config is a core i5 520m,4GB ddr3, ati 4570 512mb,1080p screen.

I was playing Burnout Paradise n my system slowed down after 10 min of gameplay! I noticed that the CPU multiplier was frozen at 9. I really dunno y that happened! I've been playing the same game for hours together back home and it din seem to affect it in any way!

I tried updating it the latest BIOS that came out (A05) and that din help either. It also happened with a few other games as well.

I tried using throttlestop to just confirm that it was the CPU. The games was playing fine for 15 min wen the system just shut off!!

So I just tried to play for one last time with throttlestop off and it was actually fine till I got a critical error msg n my screen wasn't showing color properly!!

Have I fried my graphic card somehow?? Or is my adapter just not strong enuf to handle the load n hence throttling the system??

I tried updating my drivers to v10.4 N it kept saying INF not found n I had to install it indirectly.

Any way to find out if I've screwed up the graphic card?? I'm scared to push it with a game and screw up the system!!


Thanks!!

 

Download HWMonitor. Open the progam, then play a game until it slows down. Close the game and then please post up a screenshot of the HWMonitor to imageshack.us and post a link to that.

 

Sure thanx! I shall do that now!

 

Here's the link! I played Splinter cell conviction at 1200x720 in low details which gave me pathetic frame rates of around 15 fps. The GPU heated up but I din see throttling or crashes! But the place below the touchpad is really really hot!

Here's the link to the hardware monitor screenshot!

I played Burnout again after the previous screenshot.. This time there was no throttling but the fps kept dipping from 50 to around 20 every now n then n it was quite random (as in it dint depend on the surroundings or anything).. attached another screenshot!

Please tell me if there is any reason to be concerned!! The temps that u see hv been that way ever since i got the laptop but i never experienced throttling or shutting down or the gpu showing strange colors before!

 

How are you connecting to a 220v source?

That first pic shows your GPU's highest temp was 99c.That is getting REALLY close to the TDP of the GPU.

Somethin I noticed on my 1557...

If your GPU gets to hot your CPU will throttle down to allow the GPU to cool down.Turning throttle stop on blocks this so thats why it did a hard shut off on you.

 

Oh but y now? As in the temps have been that high from the beginning!

I used to play crysis a few months back and GPU used to touch 105. Should I stop gaming or somethin?? Or get a cooler? or apply thermal paste?

Or is there anythin I can ask Dell to do bout it? I have the 2 yr warranty thing on this

 

Is it warmer than your house.

Ambient temperature makes ALOT of difference.

 

Ya it is actually!! Its probably 8 degrees warmer here!! maybe that is the problem! My adapter is getting really hot as well?? Any point in trying to get a 135W adapter? Does that help in general??

Also I have been trying to install 10.3 and 10.4 mobility drivers and i get the error saying INF not found!! Any idea y? I tried the stock drivers as well n they din work either!

 

I have been using these for about a month now with very good results.

Catalyst 10.x BETA (8.74 April 6/10) Win All - Guru3D.com Forums

If want to get them through AMD/ATIs website you have to choose


Windows 7 64bit/Mobility Radeon/ Whatever version of the card you have (5000,4000,3000)

They will give you a 1.3mb file to download and then you run that and it will download the latest mobile ATI driver.

 

I tried the new driver! Installed without any problems! the system also seems stable now.. maybe it was just a driver causing the GPU to heat up too much n cause throttling in some way......

One more thing any reason to get a 135W adapter from dell?

 

Thanx! Installed properly this time!! I think the old drivers were just pushing the temperatures too high n throttling!

One more thing! Anything to be gained from getting a 135W adapter? And a cooler? I was thinking of getting a notepal infinite

 

you're going to damage your hardware if you kerp running at temps that high... I never let my desktop CPU get above 45 and my GPU above 80.

I'm not sure about this laptop though, since I got it last week....

Edit: I just ran furmark for 15 minutes with Prime95 in the background and my Max temps were: CPU = 69 celsius GPU=83 celsius

You may want to clean some dust out of your laptop

 

Dell provides only two types of adapters- 90W and 130W. if you purchase a 135W adapter from a third party it will not be supported by your BIOS. so it will be better if you ask for a 130W adapter as a replacement from Dell by mentioning to them your current problem of adapter overheating.

 

I did try n they din provide it to me!

I still have the same problems.. i bought a Notepal infinite after I got back to LA n it din help by much.. it gets quite hot here in the afternoon and laptop throttles then.. during the nights the peak temperatures are much lesser (by around 10 C) .. Dunno wat to do really.. wanna put some thermal paste but too chicken to rip open the laptop lol!

 

My GPU (4570) was running hot, and it seemed to trip the fan on high too often. After unscrewing the plastic plate that covers the ram and hdd, and poking around a bit, blowing air on it and through the plastic grilles, my gpu runs cooler.

I think the gpu is right there, under the mouse pad, since that's the hottest point on the laptop. If you get a notebook cooler, one that hits this spot, and the cpu fan/heatsink in the back left corner, should be most helpful.

In a few days I might buy some thermal paste and re-apply it to the gpu.

 

how would u go about applying thermal paste tho? I'm not so sure on how to disassemble the laptop

 

There are some guides online for applying thermal paste, that hopefully will be clear enough for me to follow.

If you want to clean the processor and it's heatsink, then you'd need to take apart the laptop (instructions are actually on Dell's website; look for the 1558 "service manual").

But, you only need to remove three screws to get to the gpu, as far as I understand. If you take off the back cover, the one that you would take off to upgrade the ram or hard drive, then you'll find a small heatsink sitting in the bottom center of the laptop, right underneath the trackpad. My guess is that you can unscrew this heatsink, clean off the old thermal paste, and apply some new paste. Can anyone confirm this? Would it help?

 

ok that would be really easy!! can somebody confirm that??

 

Judging from this picture on Dell's site, it looks like the gpu is right next to the cpu, and shares the same heatsink.

I don't know what the tiny heatsink under the trackpad is for.
