Compatible HP Pavilion Upgrade

This 4 GB DDR3 module is built for HP Pavilion P7-1246S, P7-1261, P7-1370T and P7-1380T desktops. It installs in a 240-pin DIMM slot and runs at 1600 MHz with CL11 timings. The stick is unbuffered, non-ECC and operates at 1.5 V.

Not for ECC or Registered Systems

Buyers whose motherboards require ECC or registered memory cannot use this module. It is also unsuitable for laptops or any platform that uses SO-DIMM form factors. Systems limited to a lower maximum capacity than 8 GB should verify their limit before purchase.

1600 MHz DDR3 Speed Rating

The module is rated at DDR3 1600 (PC3 12800) with 11-11-11 latency. This speed figure is the primary specification that determines whether the part matches the system's supported memory standard.

Questions about this item

Will this 240-pin DDR3 1600MHz module run at full speed alongside the original memory in my HP Pavilion P7-1246S?

The module is rated for DDR3 1600 (PC3 12800) at 1.5V with CL11 timing. The system will negotiate the highest common speed with any installed DIMM, so mixed kits may run slower than 1600MHz.

How can I confirm the CL11 11-11-11 timings are active after installing the 4GB stick?

Open Task Manager or a tool such as CPU-Z and check the memory tab; it should report 1600MHz and 11-11-11 latency when the system is idle.

Does the package include only the single 4GB DIMM or are additional parts supplied?

The box contains one 240-pin DDR3 memory stick and nothing else; no heat spreader, cables or documentation are bundled.
