Ram memory, is it backwards compatible with older hardboards?
im looking to upgrade what i have (16mb) but do not have the hardboard handbook to check the frequency as i was given the board.

A simple answer is no. As an example of the different types of memory, there are 30 pin, 72 pin, 168 pin and 184 pin, buffered, unbuffered, EDO, DDR, PC 100, PC 133, PC 2100, PC2700, Rambus, and so on. There are web sites that might be able to help you determine what motherboard you have and its characteristics. Someone else here might have a specific site they can recommend

The best solution here (if you don't know the details of the motherboard) is to take the 16 mb RAM that is in there to a dealer and get them to tell you what you need. You may be able to discern this for yourself looking at the memory already installed. Some are even clearly labelled...but if not, any reputable dealer should be able to assist you.

The newer types of RAM will definitely not work in older systems...

Good luck! Hope this helps.

You might try www.kingston.com and use the "find memory by motherboard option". Also look on the motherboard for the the "bios chipset", (it is usually near the processor" and look for a stamp on it indicating what the MHz is. Also look on the motherboard itself for a stamped "Bus MHz, and MB type"(in the area of the memory). Some older motherboards did this. Dave

To identify your board, you need to write down the BIOS string (usually) at the bottom of the screen on the second display. first is the Video details, then when memory is counting the string is displayed at the bottom. then visit this site to trackyour motherboard http://www.wimsbios.com/
I have not failed (yet) to get details or to be able to track a suitable manual for many obsolete boards

Okay, let's look at reality here.

At 16MB of RAM, I am going to assume that you have a Pentium class motherboard with 72 pin SIMM sockets on it.

For the most part, you will be safe with 60nS memory. If the board supports the MMX series CPU's,you likely need EDO RAM.

For Pentium class Motherboards, 72 pin SIMMs need to be installed in matched pairs.

Some of these motherboards would accept the first generation of SDRAM DIMMs.
There were many configuration limits, and restrictions on the use of DIMMs on these early boards.

Either way, your sources for memory are limited.

I would save myself the frustration, and find a used PII or Super Socket 7 system.
