To get the most value for your dollar, don’t spend more on RAM than your system warrants. If you’re considering upping a 2000MHz or slower system to 256MB or 512MB of memory, instead consider a new PC.

What you have, what you need

ramThe simplest way to ensure you get the right kind of memory is to give the serial number and model name of your computer to the memory supplier, which can be the original system manufacturer, a mail-order or Web-based supplier, or a retail outlet. The supplier should be able to provide the exact memory type you need, and possibly determine compatibility with the RAM modules you have.

To decide how much memory to buy, you need to know how much you’ve got and how much more you can fit. Current …

Synclink Was Critical To SDRam Development

With Synclink, packet-oriented transactions between the controller and the modules would take place over semi-synchronous, unidirectional buses. Commands would move on one bus and responses on a second, at speeds as high as 500 Mbytes/s.

The proposal contained ideas about bus structures and signaling techniques that have not yet been approved by the Synclink working group. But the group does appear in agreement that the new interface will be based on a Ramlink-like protocol. A command burst in the protocol would contain an address, a transaction code that specified the operation to be performed, and a time at which a response should be returned to the memory controller. Thus, a memory-read operation might consist of a read address, a transaction code specifying that 64 consecutive bytes should be read, and a time stamp …
