Problems solved by technology

[0011] Both solutions produce severe loss
[0013] However, if the signal conditioning devices are placed on the motherboard, the signal conditioning devices also have configuration functions that they do not need and degrade the functionality of the memory module due to the necessary delay period afterwards

Abstract

Memory modules without signal-conditioning devices (unbuffered, unregistered) are provided in a system by using adapter cards that have signal-conditioning devices and are then operated in the manner of memory modules with signal-conditioning devices (unbuffered, unregistered). Systems can thereby be expanded in a very simple manner and can be flexibly adapted according to requirements, and for this purpose only one type (unbuffered, unregistered) of memory module is required.

Description

technical field [0001] The invention relates to a memory module installation method that does not require a signal conditioning device on a system slot, and provides a system motherboard (mother board) with a slot and several memory modules that does not need a signal conditioning device. Background technique [0002] In modular electronic systems with different configurations, a system motherboard with one or more slots is usually provided. Depending on system requirements or system configuration levels, the slots are configured or not configured with a memory module. The interfaces of these memory modules must be consistent or compatible with each other. [0003] A typical modular memory system of this type is a computer system (PC, workstation, server) with expandable basic memory, whereby slots for memory modules in the form of plug-in slots are provided on the motherboard , and is configured to have a memory module according to the required size of the basic memory. ...
