8GB DDR4 3200 ECC RDIMM for HP Servers

This 8GB DDR4 3200 ECC RDIMM module is built for HP server and workstation platforms that require registered memory with error correction. It matches part numbers P07638-B21, P07638-H21, P07638-K21, P11441-191 and P20499-001. System administrators expanding memory capacity in compatible HP systems use this single-rank 1Rx8 DIMM.

Sustained load behaviour with registered ECC

The registered buffer reduces electrical loading on the memory controller, allowing stable operation when all slots are populated under continuous workloads. ECC circuitry detects and corrects single-bit errors in real time, preventing data corruption during long compute tasks. CL22 latency and 1.20V voltage maintain consistent timing and power draw across extended duty cycles.

1Rx8 rank decides slot population limits

The single-rank 1Rx8 organisation determines how many modules the memory controller can address per channel. Systems with strict rank-per-channel limits need this exact configuration to reach maximum capacity. Builders requiring dual-rank or quad-rank density per module cannot use this DIMM.

Spurningar um þessa vöru

Does the 1.20V DDR4 3200 module run hotter or draw more power than standard server DIMMs?

It operates at the standard 1.20V DDR4 voltage, so heat output and power draw are in line with other registered ECC modules at this speed.

What must the motherboard provide for this 288-pin RDIMM to function?

The board needs DDR4 DIMM slots that support ECC registered memory at 3200 MHz and a BIOS that recognises 1Rx8 modules.

Will this CL22 1Rx8 stick work alongside other DDR4 3200 ECC RDIMMs already in the system?

Yes, if the existing modules are also DDR4 3200 ECC registered DIMMs the system will typically run all sticks at the common 3200 MHz CL22 setting.
