High-Speed DDR5 Kit for Enthusiasts

This 48GB dual-channel kit pairs two 24GB modules rated at DDR5 8400 with CL40 timings. It targets builders using 14th Gen Intel Core processors on 700 Series chipsets who want maximum bandwidth for gaming and heavy multitasking. The 1.40V operating voltage and XMP 3.0 profile deliver validated high-frequency stability out of the box.

Matched Pair with Aluminium Heatspreaders

The two modules are factory-matched to run together at 40-52-52-134 timings without manual tuning. Each stick carries a black brushed-aluminium strip set into a matte white body that dissipates heat from the ICs. Customisable RGB lighting runs along the top bar and synchronises with motherboard software. Mixing this kit with other memory is not supported.

Sustained Load Stability at 1.40V

Hand-screened DDR5 ICs maintain the rated 8400 MT/s transfer rate during extended sessions rather than only in short bursts. The 1.40V supply and dual-texture heatspreaders keep thermals controlled when all threads stay saturated. XMP 3.0 applies the 40-52-52-134 profile automatically so the bandwidth holds steady under continuous compute or rendering workloads.

Do not mix memory kits. Memory kits are sold in matched kits that are designed to run together as a set. Mixing memory kits will result in stability issues or system failure.
Memory kits will boot at the SPD speed at default BIOS settings with compatible hardware.
For memory kits with XMP, enable XMP profile in BIOS to reach the rated potential XMP overclock speed of the memory kit, subject to the use of compatible hardware.

Questions sur cet article

Will the 1.40 V required for DDR5 8400 CL40 become the first limit under sustained load?

The kit is rated at 1.40 V for the 8400 MT/s speed with 40-52-52-134 timings; sustained operation stays at this voltage unless the platform pushes higher.

How much heat and noise should I expect from the aluminum heatspreader during all-day use?

The black brushed-aluminum heatspreader passively cools the hand-screened ICs; it adds no fan noise and runs warm but within DDR5 thermal limits.

Which motherboard feature must I already have to run this dual-channel kit at its rated speed?

An Intel 700-series chipset board with an XMP 3.0-capable BIOS is needed to load the 8400 MT/s profile automatically.
