  • 5 V standard voltage ensures broad DDR3 compatibility
  • 240-pin UDIMM form factor fits ECC unbuffered server slots

DDR3 ECC UDIMM Kit

This 8GB kit contains two 4GB unbuffered DIMMs built for DDR3 servers and workstations that require error-correcting memory. Each module runs at 1333 MHz with CL9 latency and standard 1.5V operation. The dual-rank x8 organisation suits platforms designed for registered-style density in an unbuffered form factor.

PC3-10600 Interface Limits

The DDR3 1333 standard tops out at 10600 MB/s theoretical bandwidth, so throughput cannot exceed that ceiling regardless of CPU capability. Unbuffered ECC modules also impose a maximum of two DIMMs per memory channel on most server chipsets, limiting total slots to four in a dual-channel board. Systems needing higher frequencies or registered buffering must use a different memory generation.

8GB Dual-Channel Capacity

Two 4GB sticks provide 8GB in dual-channel mode, enough for light virtualisation, file serving or legacy database workloads that fit in that footprint. Workloads demanding larger datasets, heavy VM consolidation or in-memory analytics will exhaust the 8GB pool quickly, forcing swapping or requiring a platform that accepts higher-density modules.

Questions about this item

Should I pick the 2x4 GB kit or a single 8 GB module for my dual-channel server board?

The 2 x 4 GB kit populates two channels at once, giving full dual-channel bandwidth with matched modules tested together.

What does the 1333 MHz rating actually deliver inside a DDR3 1333 server?

It runs at the rated 1333 MHz with CL9 timing, providing the standard PC3-10600 bandwidth your platform expects.

Is the 240-pin ECC UDIMM interface limited to certain chipsets or voltage rails?

The 240-pin DDR3 ECC UDIMM operates at 1.5 V and fits any server or workstation board that accepts unbuffered DDR3 ECC DIMMs.
