I ran the crucial scan to find out my memory setup. I have 3 1 gig sticks installed. I wanted to put 2 gig in remaining slot and ordered one with specs for ddr2 pc2-6400. Full description of memory I received: "200-pin ddr2 sodimm pc2-6400 cl6" The stick is a little less than 2 and a half inches long. There must be some trick to put it in the long slot that's open. Can you help me? Thanks Robert Shinn

put it in an open memory slot although its recommended to add it for an even amount of memory (ie. 2, 4, 6, 8) if im not mistaken 4 slots w/ 8Gb max memory

go here: http://www.crucial.com/, and make sure all is compatible, with free memory scanner(it is safe i have used it and got no viruses)

Some motherboards are only upgradable to their allotted amount that board may only handle up to 2 gigs of RAM which is a shame. But this is the way it is. That is why I always check the board memory capacity before I buy computer boards or RAM for them. The beeps indicate error on the slots for the RAM that is why you can start up when you remove ram one at a time and replace. So use the allotted amount of RAM for that board specification or get another mother board that can handle more than 2 gigs of RAM. Sorry for the loss. Thanks for using FixYa! John

Please look into the below link for user guide manual to install Memory into your computer:

Refer to page no: 37: To Install or replace DIMM memory.

Here is the url to Crucial memory's website with the product you requested. Happy upgrading:)

I recommend that you go to the Crucial website and perform the automatic scan function. This will identify your machine and tell you what upgrades are available, taking into account what memory the machine already has and the maximum that the chipset can support.

URL for the site is:

or if that does not work just google 'crucial memory scan'

The easiest way to see what kind of memory and the amount of memory your computer can handle is to go to the Crucial Memory website (www.crucial.com) and click on the Scan my System. It will tell you the number of slots your system has, the capacity of each slot, and the type and speed of RAM that can be used.

Seems the memory is not comatable with the motherboard. Replace the old memory and visit http://www.crucial.com, they have a scanner tool which will confirm what mem can be installed.

The specifications for your Aspire 3680 only supports a max. 2Gb.
see the details.

System memory1,2
512 MB of DDR2 533 MHz memory, upgradeable to 2 GB using two soDIMM modules (dual-channel support)

DDR 2 will _not_ work the way it's supposed to in a DDR slot, if at all. If you want to see what memory your computer can use, go to crucial.com or similar website for a free scan of your computer. From the spec. sheet it looks like your machine takes a maximum of 2 sticks of 1 gig each (for a total of 2 gigs) DDR SDRAM, either 333 or 400MHz of memory

Absolutely, 2 Gigs stick of RAM exist. Unfortunately your motherboard's maximum memory supported is 2GB. This site specifies very clearly 1 gig stick max per slot:
