asked on

memory

Is there any external device you can buy to add memory to a computer?  Mine just has 4 slots and they all have 2GB.  Memory seems really expensive above 2GB a stick.  Or does anyone know of a relatively cheap computer I can buy with a lot of memory space for 2GB sticks?

I wish there was a way to add it kind of like an external hard drive for memory.

You can setup swap space on the harddisk, windows does that automatically. But of course this swapspace is a lot slower than the normal RAM. Using SSD's instead of conventional HD's can speed this up a little. But still, nothing is better than RAM. Your board should take 4GB modules, but check with the manufacturer first, as some chipsets won't go above a certain amount of RAM.
Usually, the limitation is in the BIOS. But in answer to your question, no, there is no external device to increase the memory. Your only solution is to purchase larger RAM in the architecture your PC requires, as long as the BIOS will allow it.

Hmm.

Don't think they exist anymore.  Back in the good ol' days when 286 computers roamed the earth they were available.

What is out there now is for servers.  For example http://www.ebay.com/itm/Intel-PCIe-Memory-Expansion-Board-8X-DIMM-SLOTS-SFC4URE-/150491367298?pt=US_Server_Boards&hash=item2309fc0782 and you'll find lots of references to Compaq servers and the odd Dell server for expansion cards.

This link http://ask.slashdot.org/story/02/11/16/0643228/pci-ram-extender-cards talks about not using a RAM extender on PCI slots.

The simple answer to your question is NO.

At least nothing that works very well. Certainly ReadyBoost and Swap space are not real solutions. They are bandaid solutions which prevent the computer from crashing, but cause serious performance degradation the moment they are utilized in any significant way.  I'm not sure about PCI expansion cards but I imagine that they will be a major speed bottleneck, and your server probably needs to explicitly support it.

Since you tagged "Windows Server 2008" in your question, and since consumer DDR2 and DDR3 memory these days are EXTREMELY cheap (even 4GB sticks), I assume you probably have server hardware with something like DDR2 ECC fully buffered dimms... something that is really quite expensive.

If that's the case, the best place to look for more RAM is eBay.

But unfortunately that's just the way it is. Your only other real options are to upgrade the whole server to something more modern.
@jackjohnson44 Hope I helped somewhat, many thanks for the Points.
