Eight green DDR3 memory sticks with gold contacts and black chips

SK hynix

SK hynix 64GB 8x8GB DDR3 1600 PC3-12800 240-pin CL11 1.5V Non-ECC Desktop RAM

SKU CH-PXTH-NJ899

Eight 8 GB DDR3-1600 modules totalling 64 GB at CL11 and 1.5 V for desktop upgrades

  • Total capacity64 GB (8 × 8 GB)
  • Rated speedDDR3 1600 (PC3 12800)
  • Rated voltage1.5 V
  • 64 GB total capacity from eight 8 GB modules
  • DDR3 1600 speed rated at PC3-12800 for responsive desktop performance
  • CL11 latency timing supports stable operation under load
  • 5 V standard voltage keeps power draw predictable
  • 100 % Memtest86+ verified for reliability out of the box

Kit composition

This kit supplies sixty-four gigabytes of DDR3 memory across eight 8GB modules running at 1600 MT/s with CL11 timings at 1.5V. It targets system builders who need maximum capacity on platforms limited to DDR3 technology.

Tested reliability

Every module passes a full Memtest86+ run before dispatch so the kit arrives verified at 100 percent stability. The non-ECC unbuffered design keeps latency low for standard desktop workloads without requiring server-grade chipset support.

Installation notes

The 240-pin DIMMs install in the usual desktop slots but the eight-module count demands a motherboard with eight DDR3 sockets and a memory controller able to address the full 64GB. Boards limited to four slots or lower density per channel cannot use the complete kit.

Questions about this item

Will the eight 8 GB DDR3 sticks need any firmware updates or component swaps over their service life?

The modules are non-ECC unbuffered DDR3 DIMMs with no firmware, so no updates or part swaps are required after installation.

What limit appears first when all 64 GB run at 1600 MT/s continuously?

The DDR3 1600 interface and CL11 timing set the throughput ceiling long before the 1.5 V chips reach thermal limits.

How much heat and noise should I expect from the 1.5 V kit during all-day workloads?

Each stick draws 1.5 V with no active cooling, so the kit adds minimal heat and zero acoustic noise to the chassis.
