Help Me Choose: Memory

Random access memory (RAM) is the workhorse behind the performance of your Dell Precision workstation. RAM temporarily stores information from your operating system, applications and data in current use. This gives your processor easy access to the critical information that make your programs run.

The amount of RAM you have helps determine how many programs can be executed at one time and how much data can be readily available to a program. It also helps determine how quickly your applications perform and how many applications you can easily toggle between at one time.

With 32-bit workstations, the maximum addressable memory is only 4GB, of which a maximum of 3GB is available to applications. That’s often far too little elbow room for large files in today’s high-end workstation applications.

Fortunately, the 64-bit technology in Dell Precision workstations featuring Intel® Xeon® and Core™ processors can dramatically expand that address space, shattering the 4GB limit.

Many Dell Precision workstations can use error-correcting code (ECC) or non-ECC memory. ECC memory is a feature in memory for high-end systems that detects and reports memory errors without interrupting the other operations of your system. This is important for highly detailed tasks that must be as accurate as possible and is also important when minimizing system crashes owing to error faults. Non-ECC memory does not detect and report memory errors, and is good for when you're running noncritical applications.

Registered dual in-line memory module (RDIMM) ECC memory is available on select Dell Precision workstations. RDIMM memory, or registered memory, has a register used as a pass-through for address and command signals. This allows workstations to support more RDIMMs per channel. RDIMMs consume more power but are available in larger capacities and higher ranks. The bottom line is RDIMM memory allows for extremely large memory configurations up to 192GB with Windows 7 64-bit operating system on select Dell Precision workstations.

Upgrading your memory is one of the most cost-effective ways to boost your system performance.

For memory-intensive workstation applications, Dell recommends installing as much memory as possible, populating all memory channels for maximum performance.
