Six green DDR3 RDIMM modules with gold contacts in static bag

SK hynix

SK hynix X8DAL-i 48GB (6 x 8GB) DDR3 1333 ECC Registered server RAM

SKU CH-XTYG-127KB MPN X8DAL-i

Six 8 GB DDR3 1333 registered ECC modules totalling 48 GB for Supermicro X8DAL-i servers

  • Total capacity48 GB (6 × 8 GB)
  • Rated speed1333
  • ChipsetSamsung Chipset
  • CAS latency9
  • Rated voltage1.35 V
  • ECC supportChipkill
  • 48 GB total capacity for memory-intensive server workloads
  • Six 8 GB DDR3 registered DIMMs populate all slots
  • ECC Chipkill protection detects and corrects multi-bit errors
  • 35 V low-voltage operation reduces power draw
  • 1333 MHz CL9 speed matches PC3-10600R specification

Capacity and Form Factor

This kit provides 48GB of DDR3 server memory across six 8GB registered DIMMs. Each module uses a 240-pin interface and operates at 1333 MT/s with CAS latency 9. The memory runs at a low 1.35 V and includes ECC Chipkill error correction for data integrity in multi-socket systems.

Intended Use and Limitations

The kit is validated for the Supermicro X8DAL-i platform and suits administrators upgrading that specific board to its supported memory ceiling. It is not suited for desktop or consumer motherboards that require unbuffered non-ECC DIMMs, nor for any system that cannot accept registered DDR3 modules. Builders needing higher speeds, different voltages or larger individual module capacities must select a different kit.

Deciding Specification

The registered ECC Chipkill design combined with 1.35 V DDR3 1333 operation determines whether this kit matches the target server. Only platforms that explicitly support registered DDR3 RDIMMs at this voltage and speed will recognise and stabilise the full 48 GB capacity.

Questions about this item

Will the 6 x 8GB DDR3 RDIMM kit need replacement if the server board is upgraded to a newer platform?

These modules are 240-pin DDR3 RDIMMs; newer platforms use different pin counts and memory generations, so the kit cannot be moved to a board that does not support DDR3 registered memory.

What is the first limit reached under sustained load with the 1.35 V, CL9 registered modules?

The registered buffer and ECC Chipkill add latency overhead, so the memory controller’s command queue typically saturates before the 1333 MT/s data rate becomes the bottleneck.

How much heat and power does the 48 GB kit draw when running continuously at 1333 MHz?

At 1.35 V each 8 GB 2Rx4 module draws only a few watts, so the full 6-module kit produces modest heat that standard server airflow handles without extra cooling.
