Mixing Laptop RAM

[waterjug]

I know it's not a good idea to mix RAM on a desktop, but what about on a laptop? I am currently upgrading an old HP G62. But the RAM I found in it was mix matched already. One was a hynix somehting, and the other was a Samsung planet first one with a sticker that says "Replace with HP spare" So my plan was to keep the 2GB stick, and upgrade the 1GB stick to a 4GB stick right here-   http://www.ebay.com/itm/4GB-SODIMM-HP-Compaq-G56-125NR-G56-126NR-G56-127NR-G62-AMD-DDR3-Ram-Memory-/321852663775 

Is this ok?

Mixing RAM really does not matter. Just make sure it's the same type and speed and you're fine. Honestly, I feel like I've said this about a billion times.

how do I tell the frequency of my existing RAM?

It should say on the stick.  If not, stick each one in the BIOS one at a time(not at the same time) it should say in the BIOS.

Good.  If they are the same frequency, feel free to use both at the same time, but if they are different, you can still use them.  It's just the faster one will slow down to match the slower one.

Doesn't matter if you mix RAM.  I'm running Kingston and Crucial RAM in my laptop right now.

Hey,

All that will happen if you mix RAM is that it will cause all of the RAM to go to the slowest speed, therefore putting high speed RAM in that costs more, would therefore be pointless if there is lower speed RAM in the system. Furthermore, you can find out the speeds likely on the side or through the system. I don't know how to do this however I could find out if you need to know.

 

Hope this helps

I have mixed frequencies in the past (I would imagine as I have never stopped to check what they are) and it's worked prefectly fine for me, never mixed capacities over the same channel though.

Its not pointless because it still adds more ram to the system. So basically just buy the cheapest compatible ram regardless of the speed.

True, however it would be pointless spending more on higher speed RAM if there is lower speeds in there as if you got speeds to match it would be just as effective but would not cost as much

Which is why I said "buy the cheapest compatible ram regardless of the speed."
