Memory Device
Use this window to view information for a particular memory device.
Status | Normal, prefailure, or failure performance of the connector or slot for a memory module. |
---|---|
Device Name | The alphanumeric text that uniquely identifies each memory slot, whether occupied or unoccupied. |
Size | Capacity of the memory slot expressed in MB or GB. |
Type | Synchronous dynamic random access memory (SDRAM) chip sets operate fast enough to synchronize with the CPU clock, eliminating wait states. The SDRAM chip set has two cell blocks, allowing more efficient data access. In dynamic random access memory (DRAM) each bit of storage is built from a single transistor and capacitor, allowing more memory bits to fit in the same chip area. However, DRAM has to be refreshed because the charge on the capacitor, which represents the stored bit value, decays with time. During a refresh, the memory module must read every bit and write it back at full strength. |
Speed | The rate, in nanoseconds, at which the memory module can read the second and all contiguous characters in a data word. The standard rate for SDRAM is 10ns. |
Rank | Displays the rank of the Dual Inline Memory Module (DIMM). A rank is a row of dynamic random access memory (DRAM) devices comprising 64 bits of data per DIMM. For example, Dual rank represents two rows of DRAM comprising 64 bits of data each. |
Failures | If the value is other than None, one or more of the following
strings is displayed:
