Server Memory Upgrade

This OWC module is a single 64GB DDR4 3200 ECC Registered RDIMM designed for specific Supermicro motherboards including H12SSL-CT, H12SSL-NT, H12SSW-iNR, H12SSW-NTR and X12DPG-OA. It targets administrators upgrading workstation or server platforms that require registered error-correcting memory. It is not for standard desktop computers or systems needing unbuffered or load-reduced DIMMs.

Registered ECC Requirement

The decisive specification is the registered ECC design with 2Rx4 organisation, which only functions in motherboards wired for registered modules. Mixing this stick with unbuffered or load-reduced memory will prevent the system from posting. Buyers must verify their board explicitly supports registered ECC DDR4 before purchasing.

Straightforward Slot Installation

Installation follows the standard 288-pin DIMM procedure: align the notch, press firmly until the retention clips engage, then power on. The most common issue is seating the module incompletely, which causes boot failures or memory errors. Because registered DIMMs place a heavier electrical load on the memory controller, populating every slot may require a BIOS update for full stability.

この商品に関する質問

What does the 3200 speed rating mean once the module is installed in a Supermicro board?

The DDR4 3200 module runs at up to 3200 MT/s when the motherboard memory controller supports that data rate; the actual operating speed is set by the platform firmware.

What does the PC4-25600 designation tell me about the interface and its practical limit?

PC4-25600 is the JEDEC standard name for DDR4 3200, confirming the module meets the 3200 MT/s specification and 1.2 V operation defined for that speed grade.

What physical slot and clearance does this 288-pin RDIMM need to fit?

It requires a standard 288-pin DDR4 DIMM socket; the registered design adds a buffer chip so the module will only work in boards wired for registered ECC memory such as the listed Supermicro models.
