Precision M4600 Owners Lounge

I have the same Kingston RAM but I've been seeing some strange behavior on my laptop. With 2 or 4 sticks in my system I see random power offs in both Windows 7 and Ubuntu Linux. The system literally just turns itself off.

I have run Memtest86+ on the RAM and I have not found any issues. I'm wondering if it's a problem with the laptop or the RAM. If I throw in a 2 GB stick to force all the RAM to run at 1333 instead of 1600 then everything works just fine. Anyone else see this power off behavior?

 

Since your RAM is not from Dell, Dell support may not help you.

There could only be 2 problems: defective RAM or defective mainboard.
You may try to troubleshoot by doing this:-

Lets say the 4 RAMs are A, B, C, D

Use only 2 RAMs at one time, try AB first, if everything is fine, then AC>AD>BC.... If one of the combinations give you the problem, that RAM is defective. Memtest is not everything.

If all the RAMs are ok, repeat them at the RAM slots below the keyboard. This is to test the RAM slot.

Very troublesome test, you are unlucky to have this problem. At first installation I do have Windows crash problem, happened only once and after restarting everything is fine until today. I think it could be warming up issue >_<

 

Hardly worth the trouble. RAM speed has very little impact on any practical real life performance.

Overall I agree. Latency is more of an issue than the raw speed. Unfortunately I don't see a way to change the timing used by the BIOS. There is a second XMP profile on the Kingston sticks:
666 MHz at 7-7-7-20 which I would rather use as opposed to the
800 MHz at 9-9-9-27

Does anyone know of a way to force the system to use a different XMP profile?

 

Does DEll include a contactless smart card with their system ? or i have to get one somewhere else

 

you have to get one somewhere else

 

On the M4600 IPS AdobeRGB, could someone tell me how to switch between the different screens configurations AdobeRGB, sRGB and NTSC as the optional utility show it :

I select sRGB or NTSC, click the close button, but nothing happens, If I reopen the utility AdobeRGB is selected again.

Someone to test this ?

Thanks.

 

I think you should uninstall Dell system manager, restart the computer, then reinstall Dell system manager again.
i tested mine and i can select anything i want and it wont auto select another setting when i close it and turn it back on again

 

It's an option. Just do a CTRL+F on the configuration webpage for 'smartcard'.

 

The contactless smart card reader is included when you order a fingerprint reader.
