Dual-Channel Memory

by NickMets7 / July 29, 2006 12:56 AM PDT

Hey everyone,

Can dual-channel memory be enabled in any laptop computer? If so, how identical do the RAM sticks have to be? Do they have to be from the same company, speed, chip configuration, CAS latency, etc.?

Thank you

Not usually. Why? Power, heat, battery time.

There are downsides to implementing some of the nifty desktop speed tricks into laptops.

I suggest you benchmark the laptop you think you want to see if it meets your needs.

BEWARE laptops with desktop CPUs since they usually fail in year 2 and suffer odd heat issues plus battery times fall to mere minutes.

I have a P4 and it's been good for 3 years now, and although there are heat issues which were solved by cleaning the vents and getting a cooler, my notebook serves as a desktop replacement. Today though, with all the new Core Duo and Centrino and Turion CPUs it doesn't seem possible to get a desktop processor for a laptop anymore.

So dual channel in notebooks is usually a no-go? Even in today's notebooks? That's too bad. How about in desktops? Do you need the same manufacturer of RAM for each stick, same speed, etc?

Thank you once again

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
