Frequently Asked Questions

What motherboards are compatible with this CUDIMM memory?

The Kingston FURY Renegade RGB DDR5 24GB 8400MT/s CUDIMM Intel XMP (CUDIMM) — KF584CU40RSA-24 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 CL40-48-48-96 timings, enable Intel XMP in your motherboard BIOS. This is a one-click setting in the memory overclocking section.

Can I add more memory later?

Yes, the Kingston FURY Renegade RGB DDR5 24GB 8400MT/s CUDIMM Intel XMP (CUDIMM) — KF584CU40RSA-24 is a single 24GB module. You can add additional compatible DDR5 CUDIMM modules to populate empty slots. For best performance, use matched modules of the same speed and capacity to enable dual-channel mode.

Does this memory have a heatspreader?

Yes, the Kingston FURY Renegade RGB DDR5 24GB 8400MT/s CUDIMM Intel XMP (CUDIMM) — KF584CU40RSA-24 features a Aluminum heatspreader with RGB lighting. The module height is 44.7 mm. Check clearance with your CPU cooler — tall heatspreaders may interfere with large tower coolers.

What warranty does this memory come with?

The Kingston FURY Renegade RGB DDR5 24GB 8400MT/s CUDIMM Intel XMP (CUDIMM) — KF584CU40RSA-24 comes with a Limited Lifetime warranty from Kingston.
