Compatibility & Purpose

This 64 GB kit contains four 16 GB DDR4 SO-DIMM modules built for the Acer Predator Helios 500 PH517-51-72NU, PH517-51-98Y7 and PH517-51-98EE. It targets owners of those specific notebooks who need the maximum factory-supported memory capacity.

Build Integration

Each stick uses the 260-pin SO-DIMM form factor and runs at 1.2 V unbuffered, so it drops straight into the four soldered slots without extra power or cooling hardware. The non-ECC, CL17 17-17-17 timing profile matches the platform’s native memory controller settings, leaving the existing thermal solution untouched.

Sustained Load Behaviour

Major-brand DRAM chips rated for DDR4 2400 (PC4 19200) deliver stable throughput during long rendering, compilation or virtualisation sessions. The dual-rank 2Rx8 organisation keeps bandwidth consistent across all four channels, preventing the throttling that can appear with mismatched or single-rank configurations.

Questions about this item

Does the 2400 MHz DDR4 speed limit bandwidth under sustained loads?

The kit runs at DDR4 2400 (PC4 19200) with CL17 17-17-17 timings; this speed and latency set the maximum sustained throughput for the Helios 500 PH517-51 models.

How much heat or power does the 1.2 V unbuffered kit add during all-day use?

Each 16 GB module operates at 1.2 V without a heat spreader; the low voltage and unbuffered design keep thermal output and power draw minimal during continuous operation.

Which specific Acer Predator Helios 500 models must I already own for this 260-pin SODIMM kit to work?

Compatibility is guaranteed for Acer Predator Helios 500 PH517-51-72NU, PH517-51-98Y7 and PH517-51-98EE; the 260-pin DDR4 SODIMM form factor fits only those listed systems.
