Mixing RAM?


Recommended Posts

I have a number of PC's - one of them is a video edit PC and I could do with some extra RAM in there. Currently it has an Asus P5WD2 Premium M/B with Corsair CM2X1024-6400 RAM (2Gb over two sticks). I have some spare CM2X512-8000UL RAM (4 x 512MB sticks). I'd like to put two of these in to make a total of 3Gb RAM.


Is this a good idea? Will they work happily together? Should I manually set the timings to the lowest spec of the two (5-5-5-12 I believe) and should I set the VDIMM to a particular level?


What will happen if they're all working in Dual channel mode?

Unfortunately mixing different models of RAM together in the same system will not provide positive results. Most of the time you will get errors. If you are using a 32BIt OS it would be wise to stick with the 2GB, since it will only see about 3GB even if you install 4GB.
