32GB DDR4-2933 DIMM for HP Z4 G4

This 32GB DDR4 module runs at 2933 MHz with CL21 latency and 1.20V operation. It is an unbuffered 288-pin DIMM validated for the HP Z4 G4 workstation. Intel XMP 2.0 support allows the rated profile to load automatically on compatible platforms. The module carries RoHS certification.

Unbuffered 288-pin build with XMP 2.0

The standard DIMM form factor fits regular desktop memory slots without extra clearance concerns. Unbuffered signal processing keeps the electrical path direct for typical workstation workloads. Intel XMP 2.0 lets the BIOS apply the 2933 MT/s profile without manual timing entry. RoHS compliance confirms restricted-substance limits are met.

DDR4-2933 bandwidth ceiling

At 2933 MT/s the peak transfer rate reaches PC4-23466, which caps throughput for memory-bound tasks on this platform. CL21 latency sets the minimum response window for random access patterns. The 1.20V rail is fixed by the DDR4 standard, so voltage headroom for higher frequencies is not available. Builders needing greater capacity per slot or faster data rates must choose a different module.

Questions about this item

What DDR4 standard and speed does the 7ZZ66AA-AX module run at, and what bandwidth does that cap?

The module is rated DDR4-2933/PC4-23466, so the peak transfer rate is capped at 23466 MB/s.

What physical slot and pin count does this 32 GB DIMM require?

It uses a standard 288-pin DDR4 DIMM slot, unbuffered, and fits any desktop board with that socket.

How is the XMP 2.0 profile enabled, and what step do builders often miss?

Enter the BIOS, enable XMP 2.0 for the installed DIMM, then save and reboot; skipping the save step leaves the module at default speed.
