Compatible DDR3 1333 Upgrade

This 4 GB DDR3 module runs at 1333 MHz with CL9 latency and standard 1.5 V operation. It uses a 240-pin unbuffered DIMM form factor built with major-brand chips. The kit is designed as a direct replacement for the Crucial CT51264BA1339J part number.

Suitable for legacy desktop refresh

Owners of older AMD or Intel desktop platforms that accept DDR3 1333 non-ECC memory can use this stick to add capacity or replace a failed module. Systems requiring ECC, registered DIMMs, or speeds beyond PC3-10600 should select a different product.

Tested reliability and lifetime coverage

Every module undergoes quality-assurance testing before shipment to confirm stable operation at the rated frequency. A lifetime warranty and US-based technical support are included with the purchase.

Questions about this item

Does my motherboard need a 240-pin DDR3 DIMM slot to use this module?

Yes, this is a 240-pin DDR3 DIMM that requires a matching DDR3 desktop memory slot on the motherboard.

Will this 1.5 V DDR3 1333 module work if I keep my existing 1.5 V DDR3 1333 sticks?

It will operate alongside other 1.5 V DDR3 1333 modules at the shared speed and voltage.

How can I confirm the module is running at 1333 MHz with CL9 timings after installation?

Check the memory frequency and CAS latency reported in your BIOS or a system-information tool such as CPU-Z.
