Cache Memory
How to choose cache memory
Cache protection
Decide between a flash-backed write cache for power loss protection and a plain memory module for simpler tasks.
Security vs performance
Pick a TPM card from Electronics Accessories only when Windows 11 support is the goal, not for storage speed.
Capacity tier
Weigh the 1Gb capacity against the 2Gb tier based on how busy your storage array is.
Connector type
Match the physical format: 244-pin DDR3 mini-DIMM for cache memory, 20-pin LPC for security modules.
Speed rating
Confirm whether your controller expects 1333MHz or 1600MHz before selecting a module.
What's good
- Flash-backed write cache modules in the Memory sub-type keep queued writes safe through a power loss.
- Electronics Accessories includes TPM 2.0 modules that add Windows 11 readiness to older systems.
- A 2Gb capacity tier serves heavier array workloads than the 1Gb tier without choking the cache.
- The 244-pin DDR3 mini-DIMM form factor fits compact server memory banks where space is tight.
- Storage cache modules under Electronics offload write duties from the main system memory.
Things to watch
- Plain memory modules without flash backup, such as basic Smart Array types, lose cached data during a power cut.
- TPM modules need a specific 20-pin LPC socket, so a mismatched board will not accept the card.
- A 1600MHz module brings no benefit in a controller limited to 1333MHz, leaving the speed unused.
- All these parts sit inside the chassis, so installation means downtime and careful static handling.
Care & maintenance
Anti-static storage
Store spare modules in anti-static bags until they are fitted.
Contact care
Wipe the gold contacts with isopropyl alcohol if the server logs memory errors.
Reseating
Reseat the mini-DIMM during routine service to prevent a loose connection.
Physical care
Avoid bending the 244-pin edge while handling the part.
