DDR2 voltage

[xxxJCxxx]

I have the following Mobo:

ASUS P5KC AiLifestyle Mobo


Board has 4 DDR 2 slots
specs say I can use PC2 - 6400 DDR2
Can I put above ram with 2.2v in Mobo? What compatibility issues are there with ram voltage? (Sorry if stupid Q)

Thanks in advance.

You could put them in, but unless you already own that memory, get modules that require 1.8V to run properly. If you use those, you'll have to set the voltage manually to 2.2V. I presume that you already know, but don't install both DDR2 and DDR3 at the same time.

Great...thx. I thought I could do it mannually, but wasn't sure. I'm not sure what I'm gonna do. I can get the 2.2v RAM very cheap, half cost of 1.8v. I was just wondering if it was an option. I'm guessing it will run hotter too.

It depends on what RAM it is. Some RAM rated at 2.2V will run fine at 1.8V-2.0V with relaxed timings. It will definitely run hotter at 2.2V. If you have the part number, it's easy to check the specs. If it only runs at 2.2V, I'd stay away from it.
