RAM Upgrade for H30-50

Planning on a RAM upgrade but can't find the exact same module where I live.

The PC came with a Ramaxel 4 GB module []


The closest I could find was this Kingston one,



Problem is the voltage difference, the Kingston is 1.5V and the existing Ramaxel is 1.35V. There is no clear consensus on whether using the two together is okay and if the system will be stable. Help!


And will dual channel work with these two modules?

Re: RAM Upgrade for H30-50

To run any memory in dual channel all you need to do is install the memory in matched pairs. That means that you need to match the memory speed, CL timing and same type. Also you may need same size and same voltage memory. I'd suggest getting a 8GB (4GB x 2) kit from Cruicial- it costs $37.99, which looks cheaper than the one you linked.

Re: RAM Upgrade for H30-50

That isn't available here either. Found this 4GB module, will try it out and let you know.

While I agree that getting a matched kit is far simpler, I'm just not too keen on "wasting" the old RAM.


Thanks for the suggestion EricX!
