Questions & Answers
What are the key specifications of SKU 0A65732 4GB PC3-12800 DDR3-1600 RDIMM?
This module offers 4 GB capacity, 1600 MT/s transfer rate, PC3-12800 data bandwidth, DDR3 technology, registered ECC buffering, and a 240-pin RDIMM form factor.
Is the 4GB PC3-12800 DDR3-1600 RDIMM compatible with my server motherboard?
It’s compatible with servers and workstations supporting 240-pin DDR3 registered ECC memory at 1.5 V and 1600 MHz clock speed; verify your motherboard’s QVL for confirmation.
Does this memory module support ECC error correction?
Yes, this RDIMM features ECC (Error-Correcting Code) to automatically detect and correct single-bit memory errors for enhanced data integrity.
What’s the difference between RDIMM and UDIMM?
RDIMMs include a register chip to buffer commands and addresses, reducing electrical load for higher stability, while UDIMMs are unbuffered and lower cost.
Can I mix this 4GB RDIMM with non-registered (UDIMM) memory?
No, mixing registered (RDIMM) and unbuffered (UDIMM) modules is not supported; use only identical RDIMM modules for system stability.
How many modules can I install per channel?
Most server platforms support one RDIMM per channel; consult your server manual, as some chipsets allow two but may reduce performance.
What is the CAS latency for PC3-12800 DDR3-1600?
This module typically operates at CAS latency 11 (CL11), balancing low latency and high throughput for reliable performance.
What voltage does the DDR3-1600 RDIMM require?
It runs at a standard 1.5 V, ensuring compatibility with most DDR3-capable server power designs.
How do I install the 240-pin DDR3 RDIMM?
Align the module notch with the slot key, insert firmly until latches click, power off before installation, and follow anti-static handling procedures.
Will this module work in dual-channel or quad-channel setups?
Yes, when installed in matched pairs or sets per motherboard guidelines, it enables dual- or quad-channel interleaving for higher bandwidth.
What operating temperature range does this module support?
It’s rated for 0 °C to 85 °C ambient operation, suitable for standard data center and office environments.
What warranty coverage is included with the 4GB RDIMM?
This module comes with a limited lifetime warranty covering manufacturing defects and failure under normal use conditions.
Can I return or exchange the module if it’s incompatible?
Yes, our 30-day return policy applies provided the module is undamaged and in original packaging with proof of purchase.
How does upgrading to PC3-12800 DDR3-1600 benefit system performance?
It boosts memory bandwidth to 12.8 GB/s per module, reduces latency, and increases multitasking capability in server applications.
Does using registered ECC memory require BIOS configuration?
Most servers auto-detect ECC RDIMMs, but you may need to enable ECC and set memory speed in BIOS/UEFI for optimal operation.
Is this module compatible with DDR3-ECC LRDIMM platforms?
No, RDIMMs and LRDIMMs are not interchangeable; use only RDIMM-specified slots as indicated in your server’s memory population guide.
How can I verify the module’s authenticity and grade?
Check holographic labels, serial numbers, and SPD information via BIOS or system utilities; genuine modules match manufacturer specifications exactly.
