How To Know If I Have Free Ram Slots

When purchasing a new Server, Workstation or PC to support an expansion card one of the most important things to determine is what type of slot does the motherboard have. There are 3 types of slots that have been used for over the years: ISA, PCI, and PCI Express (PCIe). These are also the most common types of slots that computer motherboards have had for expansion cards. Let’s take a look at each of these:

ISA Slots

Open the back side of the laptop where RAM is inside. If there is no paper label who indicates which type of module is (DDR2 or DDR3, Mhz speed, Gb), extract a single RAM from the slots, take a photo, zoom and count pins, and look how are distributed in the module (21 pins, space and 52 pins, as example, could be a DDR2 for your computer). Incorrect number of SODIMM memory slots available in Task Manager I am upgrading the available memory for my Lenovo IdeaPad Y510p. In looking at my options, I found that within the Performance tap of Task Manager that it shows my laptop having 'Slots used: 2 of 4' so I had hoped to use the other two ports for additional memory. It's pretty rare that I have the chance to open one of our ESXi hosts, but I need to know if all RAM banks are being used. If so, I'll need to order and install a second processor so I can add more RAM to the hosts (Dell Poweredge R410 & R610). When we had physical servers I would run the Crucial memory scanner.

I have 128's coming out my ears (yeah, I know, don't get smart.) and a few 256's, and it would be nice to put them to use. Computer only has 2 slots and even a couple of 512's are out of my budget.

The ISA Slots are shown in Green in image to the right. This is the oldest slot type that is still available today. Computers with ISA slots are no longer available from major computer manufacturers, Ram PC Systems still sells industrial class systems with ISA slots.

PCI Slots

PCI slots were the replacment for ISA slots. The PCI Slots are shown in the Red box in the image. PCI slots come in several different versions including 5 volt and 3.3 volt slots, and 32-bit and 64-bit PCI-X slots. PCI slots are going away as well but are still available from some major computer manufacturers but they usually only offer one PCI slot. Ram PC Systems has several different systems available with 2 or more PCI slots.
