Capacity and platform fit

This 48 GB kit ships as two 24 GB DDR5 modules rated at 8000 MT/s with CL38 timing and 1.35 V operation. It targets Intel 700 and 800 series platforms including Z790, Z890, B670 and B760 chipsets for high-performance gaming or content-creation builds. Buyers who need more than 48 GB of memory should look elsewhere.

Intel XMP 3.0 profile

The kit includes an Intel XMP 3.0 profile that stores the 38-48-48-128 timings and 1.35 V voltage in the SPD. Enabling the profile in the BIOS applies the rated DDR5 8000 speed without manual tuning. Systems that cannot load XMP 3.0 profiles will run at standard JEDEC speeds instead.

Aluminium heatspreader and 288-pin layout

A streamlined white aluminium heatspreader covers each module to dissipate heat during sustained loads. The 288-pin DIMM form factor fits standard DDR5 desktop slots, and the dual-channel kit populates two slots on compatible motherboards. No onboard lighting is present.

Questions about this item

Will this kit run at 8000 MT/s on an Intel Z790 board with a Core Ultra 200-series CPU?

Yes, the kit is validated for Intel 800-series chipsets and Core Ultra 200-series processors, and the XMP 3.0 profile sets 8000 MT/s at CL38 with 1.35 V.

Does the 48 GB dual-channel kit fit in a standard four-slot ATX motherboard?

The two 24 GB modules use the regular 288-pin DDR5 form factor and a low-profile aluminum heatspreader, so they install in any standard DDR5 DIMM slots without clearance issues.

What BIOS setting is needed to reach the rated speed without manual tuning?

Enable the Intel XMP 3.0 profile in the motherboard BIOS; it automatically applies the 38-48-48-128 timings and 1.35 V required for 8000 MT/s operation.
