Can I do 4Gb with 2GB DDR3, Dual Channel.

[nsahawks7]

Ok. Well i have 2x2 Microcenter Brand 1066Mhz DDR3 Ram and my computer has been slowing down whenever i multitask. So i was wondering if i could take out a 2gb module and add a 4GB DDR3 (1333mhz). They are different brands (Microcenter and Corsair) and different speeds but will it function properly? I checked my motherboards manual online and i couldnt find anything that said i couldnt, but nothing said i could either.. help? Specs if needed.

Biostar H61MLV
I5 2400
Hd 7770
4gb ram
Windows 7 Ult. 64bit

Thanks.

You will drop back to single channel with your proposed solution. Not really a big deal.

Also, if your BIOS memory setting is set to AUTO, the system will default (properly) to the slower of the installed memory modules.

Your best bet would be to install matching 4GB modules. But the mixed modules should work, only at the slower speed and in single channel (really not a big deal in and of itself).

The manual(page 9) says the memory must be the same density.

What does it mean when they say same "density"?
