G.SKILL Aegis 8GB DDR4-2666 CL19

This single 8GB DDR4 module runs at 2666 MT/s with CL19 latency and 1.20V operation. It carries an Intel XMP 2.0 profile for automatic configuration on supported platforms. The black and red heat spreader distinguishes the Aegis line in a gaming build.

CL19 19-19-19-43 timing at 2666 MT/s

The decisive specification is the rated speed of DDR4-2666 (PC4-21300) combined with CL19 primary latency and 19-19-19-43 sub-timings. These figures determine whether the module matches the memory controller capabilities of the target motherboard and CPU.

Sustained-load behaviour with XMP 2.0 profile

Under continuous workloads the module maintains its 1.20V setting and rated timings without requiring manual voltage increases. The hand-selected ICs and validation across major motherboard brands aim to deliver stable throughput during extended gaming or rendering sessions rather than only in short benchmarks.

Questions about this item

What does the DDR4 2666 speed rating mean for my system?

The module runs at 2666 MT/s, giving your CPU a peak transfer rate of PC4 21300 bandwidth when the platform supports that data rate.

How does the Intel XMP 2.0 profile affect the timings?

The XMP 2.0 profile sets the stick to CL19 with 19-19-19-43 timings at 1.20 V so the motherboard can apply those settings automatically.

Will this single 8 GB stick fit my standard desktop motherboard?

Yes, it uses a regular DDR4 DIMM form factor with a black and red heat shield that fits standard desktop memory slots.
