Frequently Asked Questions

What motherboards are compatible with this CUDIMM memory?

The G.Skill Trident Z5 CK DDR5 48GB (2x24GB) 8400MT/s CUDIMM Intel XMP (CUDIMM) — F5-8400C4052G24GX2-TZ5CK is a CUDIMM (Clocked Unbuffered DIMM) module requiring a motherboard with CUDIMM support. This is available on Intel Arrow Lake (LGA 1851) platforms with Z890 and B860 chipsets. CUDIMM modules are NOT backward-compatible with standard UDIMM DDR5 slots on older platforms.

Do I need to enable Intel XMP in BIOS?

Yes. Out of the box, DDR5 memory runs at JEDEC default speed (typically 4800 MT/s). To achieve the rated 8,400 MT/s with CL40-52-52-116 timings, enable Intel XMP in your motherboard BIOS. This is a one-click setting in the memory overclocking section.

Does this kit run in dual-channel mode?

Yes, the G.Skill Trident Z5 CK DDR5 48GB (2x24GB) 8400MT/s CUDIMM Intel XMP (CUDIMM) — F5-8400C4052G24GX2-TZ5CK includes 2 modules which enable dual-channel mode when installed in the correct DIMM slots (typically A2+B2 or slots 2+4). Dual-channel doubles memory bandwidth compared to single-channel configuration. Check your motherboard manual for optimal slot placement.

Does this memory have a heatspreader?

Yes, the G.Skill Trident Z5 CK DDR5 48GB (2x24GB) 8400MT/s CUDIMM Intel XMP (CUDIMM) — F5-8400C4052G24GX2-TZ5CK features a Aluminum heatspreader. The module height is 44.0 mm. Check clearance with your CPU cooler — tall heatspreaders may interfere with large tower coolers.

What warranty does this memory come with?

The G.Skill Trident Z5 CK DDR5 48GB (2x24GB) 8400MT/s CUDIMM Intel XMP (CUDIMM) — F5-8400C4052G24GX2-TZ5CK comes with a Limited Lifetime warranty from G.Skill.
