Laptop Freeze

Hi guys. :hi2:
i donno what seems to be the problem.
my laptop freeze with long strange sound.
for example, while playing music, suddenly it freeze with long strange sound and then the music resume back.
This happened out of nowhere.Like every week.

i happened to look the readings while freezing,
free memory = 13GB
GPU Temp = 55 °C
CPU core 1,2,3,4 Temp = 54-57 °C
Hardisk Temp = 50°C

My laptop specs :
Alienware m17xr3
GTX 675M
Core i7 2860QM

what seems to be the problem?

 

Could be an NV driver issue. Are you using the dell one or have you updated it? Did you put the 675m in the R3?

This has been happening to dozens of users of NV card users in the last 6 months. Get 'latencymon' and run it. This will check for the problem of excessive latency causing audio/video drop-outs.

HTH

 

Can u give the link for the dell driver and is there any possibility it might fixing this problem?
yes, i've updated it.currently using v331.82.
and the 675m is non standard part.

Here is latencymon screenshot on my system.

It says that the problem may related to power management, disable CPU throttling setting in control panel and bios setup.

My power management i set it at high performance both in windows control panel and alienware command centre.
Here's other screenshot for in-depth latency test measured on CPU. How to disable CPU throttling setting in control panel?

My graphic card bios 70.24.43.00.0D (P1314-0005).My DMI Bios version is A12.

I google on youtube and bump into this video.
Windows 8 DPC latency test using latencymon - YouTube
Can i use that solution?but i have windows 7 64bit.

It's quite old but a good starting point.

I think that message is the 'stock' response to a level of over 1000us on the DPC. You have to have those settings you have for the GPU as it's not supported under Optimus.

I'm not a CPU guru by any means. I did make an attempt with my R3 but quickly realised that I had to do so much work to get at things I am used to on desktop builds I just use the stock bios overclock and don't even look at it.

I took a look at that fix and that is interesting. Seems a little too simple and I have to wonder what other effects it has? It may work in win7 but I try to avoid bcedit commands

You could be into a reinstall of win if it's just got jacked up

 

Hi.
I think in the mean time, i should try installing the driver and will let u know what latencymon analysis feedback.
I don't quite understand what u meant by this sentence "You have to have those settings you have for the GPU as it's not supported under Optimus.".
U used the stock bios overclock?is it the one with title "original 675M" bios that u gave me to flash my graphic card before this?
I guess i will avoid bcedit commands then.

 

Yes give that driver a try and see if it has better figures. I was confused about the power options on the GPU, you just have to have the on-board disabled (or you have a 120hz display).

That vBIOS is totally standard and the latest revision. I was referring to CPU overclock. In the main BIOS there are options for overclocking the CPU IF dell decided to support it with the CPU you have. Just have a look around. I have 3 levels to choose and it set the multipliers and a couple of other settings for you.

Check out that older driver and see how it goes...

 

Have you tried running AlienAutopsy or monitoring the temperatures under heavy load?
