NT5CC128M16IP-DI DDR3 Memory Chip for Antminer S9 Control Board
The NT5CC128M16IP-DI is a DDR3 memory chip designed for use on the Antminer S9 control board. The chip's 8n prefetch architecture + differential clock and data strobe enable high-speed double-data-rate transfers up to 1866 Mb/s/pin — restoring full control-board performance after a RAM failure.
Control and address inputs are synchronised to an externally supplied differential clock pair; all I/Os are source-synchronous with single-ended DQS or differential DQS pairs. The chip is JEDEC DDR3 compliant and supports SSTL_15 (1.5 V VDD/VDDQ) — covering the standard mining control-board layout.
Typical Failure Modes Solved
- Antminer S9 control board fails to boot — DDR3 chip dead, kernel can't allocate RAM.
- Random crashes during mining — degraded RAM cell flipping bits under load.
- "DRAM not detected" boot error — chip not responding to address strobes.
- Production refurbishment — bulk DDR3 stock for S9 control-board rebuild lines.

FAQ — NT5CC128M16IP-DI DDR3
Q: DDR3 vs DDR3L — which to use?
A: This chip supports both VDD/VDDQ rails. Match the supply rail your control board uses (1.5 V standard DDR3 vs 1.35 V DDR3L) — check the PMIC on the board.
Q: BGA rework required?
A: Yes — DDR3 chips are BGA packages. Reballing requires a hot-air station, stencil and dry-bake of the chip + board before reflow. Bench rework only.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
