@ BW-userx

Code:

lsusb -t or lsusb -v

Confused at your asking the Op for this as it only tells you info about the USB hub and items connected, nothing about the installed memory. :scratch:

so he can double check his he got ripped off USB ports

sorry for caring too much , not :D

[QUOTE=Soadyheid;5639483]Being a laptop I'd reckon you have only two SODIMM modules, the first, P/N F3-10666CL9-4GBSQ is a "4GB DDR3 PC10600/10666 1333MHz module" (See here)

The second is P/N HMT451S6MFR8A-PB which is a "Hynix 4GB PC3-12800 DDR3-1600MHz non-ECC Unbuffered CL11 204-Pin SoDimm 1.35V Low Voltage Single Rank Memory Module Mfr P/N HMT451S6MFR8A-PB" (See here)
So, it looks to me that you've got two SODIMMs of differing specs fitted which could cause problems.

Can you see 8Gb at present or just 4Gb? Your post implies 4Gb which would mean the second may be fitted but not seen by the system as it's incompatible.

dmidecode implies the Max memory would be 16Gb which seems a bit large for a humble netbook. Hmmm... The Acer spec says 8Gb. :scratch: Interesting, probably the memory management chip max memory handling value.

There are indeed two slots. The command "free -h" gives me 7803 GB, so both RAM sticks are in use. I haven't noticed any problems yet, despite the mismatch.

to get a closer look at your hardware.

Code:

$ lsusb -t

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M

    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M

        |__ Port 4: Dev 3, If 0, Class=Human Interface Device, Driver=usbhid, 12M

        |__ Port 4: Dev 3, If 1, Class=Human Interface Device, Driver=usbhid, 12M

        |__ Port 4: Dev 3, If 2, Class=Human Interface Device, Driver=usbhid, 12M

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M

    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M

        |__ Port 1: Dev 23, If 0, Class=Wireless, Driver=btusb, 12M

        |__ Port 1: Dev 23, If 1, Class=Wireless, Driver=btusb, 12M

        |__ Port 3: Dev 4, If 1, Class=Video, Driver=uvcvideo, 480M

lsusb -v gave me a gargantuan list, will post if someone is interested.

Apologies, just shows it pays to READ the WHOLE of the initial post!! :doh:

I'm not the sharpest tool in the box at 1:00am. :redface:

@ cursed

From the Acer spec, as I mentioned above, it looks like you've got the maximum memory fitted!

NP, sometimes I use a modify version of Evelyn Wood speed reading myself, and :idea: get some sleep. :idea: Man cannot live on java alone.

A long time ago. When I had my Acer 5250 large screen laptop.

I tried all the dmi commands and others listed on the net.

Those commands returned that my ram was ddr2. Lucky for me. I had a easy access door with a couple of screws to pull the plastic cover off and look.

It was a wonderment to me when I saw ddr3 on the ram sticks. Crucial ram internet site ram checker also reported my laptop had ddr3.

So I decided after that. It is just better to physically look at what you have vs relying on software to tell you. What was unusual about all of this. dmi and other commands reported correctly the ram on my other gear.

Edit: I know the OP mentions they have a hard time with accessing the ram sticks. As mentioned earlier. Crucial is probably your safest bet then. What I find funny.
A ram upgrade will require the dis-assembly of the Acer laptop anyways. So why order the ram 1st? If unsure?
