The manufacturer specs often lie, too. I am running 8gb in a laptop listed at 4 max. Search around on the net to see if someone tried already. The size of each chip, not just dimm size matters, too. <div class="gmail_quote">On Sep 6, 2012 12:44 PM, "Patrick Goupell" <<a href="mailto:patrick@upmerchants.com">patrick@upmerchants.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> On 09/06/2012 12:12 PM, Charles Ulrich wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi Troy, Ubuntu will be able to use any amount of RAM that machine's motherboard will recognize. However, if the laptop's manual says that it only accepts up to 1GB of RAM, then 1GB of RAM is the hard limit no matter which operating system you install. You can also try a more lightweight distribution (such as Xubuntu) to make things feel a little speedier. </blockquote> If you currently have a 1 gb memory module installed and there is an open memory slot, then you should be able to install a 1 gb memory module into it. Ubuntu would then be able to use it. You can do a search on your particular hp laptop make and model for its "specifications". That should tell you the maximum memory allowed per slot and thusly the max for the computer.
