System-specific DDR4 kit for HP Z workstations

This 16 GB kit contains two 8 GB DDR4 DIMMs built for HP Z238 and Z240 tower and SFF workstations. The modules are unbuffered, non-ECC and run at 1.2 V. They install directly into the four DIMM slots these platforms provide.

2400 MHz CL17 speed grade

The memory operates at DDR4-2400 with a CAS latency of 17 and 17-17-17 timings. This exact speed grade is required for stable operation on the listed HP workstations; faster or slower modules may not be recognised by the system BIOS.

Steady throughput under continuous workloads

Rated at PC4-19200, the kit sustains its 2400 MHz data rate during extended compute tasks such as rendering or large dataset processing. The 2Rx8 organisation and major-brand chipset maintain signal integrity without a heat spreader, keeping performance consistent over long sessions.

Questions about this item

Will the 2400 MHz rating actually run at that speed once installed in my HP Z240?

Yes — the modules are rated DDR4-2400 (PC4-19200) and will operate at 2400 MHz provided the workstation's memory controller supports that frequency.

These are 288-pin DDR4 DIMMs — does the Z238/Z240 use the same standard, and is there any speed ceiling I should know about?

The Z238 and Z240 Tower/SFF platforms accept 288-pin DDR4 DIMMs; the kit's rated 2400 MHz is the maximum JEDEC speed for these modules.

What physical clearance do the sticks need — do they have a heat spreader that could block the CPU cooler?

No heat spreader is fitted, so the bare 288-pin DIMMs fit the standard 1.2 V slot height in both Tower and SFF chassis.
