Computer Memory Solutions 16GB (4x4GB) DDR2 3200 ECC Registered DIMM B48

SKU CH-MQ7Y-1RGRD

Four 4 GB DDR2 ECC registered DIMMs add 16 GB to an IBM Intellistation Z Pro 6223

  • Capacity16GB (4 x 4GB)
  • Type240-Pin DDR2 SDRAM
  • SpeedDDR2 400 (PC2 3200)
  • CAS LatencyCL3
  • Timing3-3-3
  • Voltage1.8V
  • 16 GB kit adds server-grade capacity
  • Registered ECC design protects data integrity
  • DDR2 400 MHz matches system specification
  • Four 4 GB modules fill available slots
  • Validated for IBM Intellistation Z Pro 6223

Targeted Server Upgrade

This 16GB kit contains four 4GB DDR2 registered DIMMs built for the IBM Intellistation Z Pro (6223-xxx). Each module runs at 400 MHz (PC2-3200) with CL3 timing at 1.8V. The registered design and ECC support match the workstation's Chipkill-capable memory architecture.

Compatibility Constraints

The system accepts only one dual-rank kit in the first bank; this 2Rx4 kit fills that role. Builders needing additional capacity must add single-rank modules in the second and third banks. Buyers who want more storage or non-ECC memory for consumer platforms should look elsewhere.

Dual-Rank Bank Rule

The motherboard permits a single dual-rank kit in the first bank only. Installing this 4 x 4GB kit there satisfies the 16GB maximum when paired with single-rank kits in the remaining banks.

Questions sur cet article

Should I buy the 16GB kit or split it across the three banks of my Intellistation Z Pro 6223?

The system accepts only one dual-rank kit in the first bank. To reach 16GB, install one 8GB dual-rank kit in bank one and two single-rank 4GB kits in banks two and three.

What does the PC2-3200 rating deliver inside the Intellistation Z Pro?

The modules run at 400 MHz with CL3 timing, giving the rated PC2-3200 bandwidth when the platform memory controller operates at its native DDR2 400 speed.

How does the 240-pin DDR2 registered interface limit what I can install?

The registered 240-pin DDR2 DIMMs require the server chipset's registered buffer; they will not work in unbuffered desktop boards and the Intellistation caps dual-rank kits to the first bank only.
