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.
Failures If the value is other than None, one or more of the following strings is displayed:
  • Single bit warning error rate exceeded
  • Single bit failure error rate exceeded
  • Multi bit error encountered
  • Single bit error login disabled
  • DIMM disabled by way of spare memory activation
