Server Memory Upgrade

This 4 GB DDR3 registered DIMM is built for servers and workstations that require ECC error correction. It replaces Hynix modules HMT151R7AFP8C-G7, HMT151R7BFR8C-G7 and HMT151R7TFR8C-G7 in compatible systems. The module runs at 1066 MHz with a CL7 latency and standard 1.5 V operation.

Registered ECC Requirement

The single specification that decides fit is the registered ECC RDIMM 4Rx8 organisation. Your motherboard must support registered error-correcting memory with this rank configuration; unbuffered or non-ECC DIMMs will not work in its place. Verify the platform documentation before ordering.

240-Pin DIMM Installation

Installation follows the standard 240-pin DDR3 DIMM procedure: align the notch, press firmly until the retention clips lock. The usual issue is mixing registered and unbuffered modules or exceeding the server's maximum rank count per channel, which prevents the system from posting.

Questions about this item

What does the 1066 MHz speed mean once the module is installed in a server?

The module runs at 1066 MHz DDR3, delivering a PC3-8500 data rate of 8500 MB/s when the platform supports that frequency.

How does the registered DDR3 interface affect what the system can use?

The 240-pin registered DIMM presents a buffered signal to the memory controller, so the motherboard must support registered ECC DDR3 to operate correctly.

What physical slot and clearance does this 4Rx8 module require?

It fits a standard 240-pin DDR3 DIMM socket; the 4Rx8 organisation uses the full module height, so verify that the server chassis allows full-height DIMMs.
