What this module is and who needs it

This A-Tech 8 GB DDR3 registered DIMM replaces Micron MT36JSZF1G72PDZ-1G1D1 and MT36JSF1G72PDXZ-1G1D1 modules in server and workstation systems. It delivers ECC error correction and registered signalling for platforms that require those features. Buyers who need unbuffered desktop memory or a different DDR generation cannot use this module.

The specification that decides fit

The module runs at DDR3 1066 (PC3-8500) with a CL3 latency, 1.50 V operation and a 4Rx8 organisation on a 240-pin DIMM. Your system must support registered ECC DDR3 at this speed, voltage and rank configuration; otherwise the module will not function.

Installation and common pitfalls

Insert the 240-pin DIMM into a compatible registered DDR3 slot until the retention clips lock. The most frequent issues are mixing registered and unbuffered modules, exceeding the platform's maximum rank count per channel, or installing in a board that only accepts unbuffered memory.

Questions about this item

How does DDR3 1066 (PC3-8500) perform once installed in a server?

The module runs at 1066 MHz with CL3 latency, delivering the rated PC3-8500 data rate; ECC and registered buffering add error correction and signal integrity for stable operation under sustained workloads

What does the PC3-8500 designation limit in practice?

PC3-8500 caps the maximum transfer rate at the DDR3 1066 standard, so the DIMM cannot exceed that bandwidth even if the platform supports faster DDR3 speeds

What physical slot and clearance does this 240-pin RDIMM require?

It fits a standard DDR3 240-pin DIMM socket; the registered design adds a buffer chip, so verify the motherboard supports registered modules and has enough height clearance for the 8GB stick
