Frequently Asked Questions

What systems is this memory compatible with?

The G.SKILL Zeta R5 DDR5 R-DIMM 64GB (4 x 16GB) DDR5-6400 CL32 Memory Kit is RDIMM server memory with ECC error correction. It requires a server or workstation motherboard with RDIMM support. NOT compatible with standard desktop motherboards. Check your server's QVL (Qualified Vendor List) for compatibility.

What speed does this memory run at?

The G.SKILL Zeta R5 DDR5 R-DIMM 64GB (4 x 16GB) DDR5-6400 CL32 Memory Kit runs at 6,400 MT/s with CL32 timings. This is a JEDEC standard speed that works automatically without BIOS configuration.

Does this kit run in dual-channel mode?

Yes, the G.SKILL Zeta R5 DDR5 R-DIMM 64GB (4 x 16GB) DDR5-6400 CL32 Memory Kit includes 4 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 support ECC error correction?

Yes, the G.SKILL Zeta R5 DDR5 R-DIMM 64GB (4 x 16GB) DDR5-6400 CL32 Memory Kit includes ECC (Error-Correcting Code) support, which detects and corrects single-bit memory errors. This is essential for servers, workstations, and mission-critical applications where data integrity is paramount.

What warranty does this memory come with?

The G.SKILL Zeta R5 DDR5 R-DIMM 64GB (4 x 16GB) DDR5-6400 CL32 Memory Kit comes with a Limited Lifetime warranty from G.Skill.
