HP Pavilion P7 series upgrade kit

This 8 GB kit contains two 4 GB DDR3 modules built for the HP Pavilion P7-1174, P7-1154, P7-1148P and P7-1147C desktops. The 240-pin DIMMs run at 1333 MHz with CL9 timings and 1.5 V. It is not for owners of other HP lines or for systems that require ECC or registered memory.

Low-voltage unbuffered operation

The modules are unbuffered non-ECC parts rated at 1.5 V, so they draw modest power and run quietly in the original chassis. No heat spreaders are fitted, leaving airflow unchanged. The dual-rank 2Rx8 organisation matches the factory specification for these Pavilion models.

Replaces factory 4 GB or 8 GB configurations

The kit fills two of the four available slots and supports the platform maximum of 16 GB. Buyers who want more storage or who need a second kit for a different motherboard should look elsewhere. The jump is worthwhile when the system currently runs with less than 8 GB and the workload benefits from extra capacity.

商品問答

How do I install the 240-pin DDR3 modules in my HP Pavilion P7-1174 and which slot order avoids the common mistake?

Power off and unplug the tower. Open the case and locate the four 240-pin DDR3 slots. Insert each 4 GB stick vertically until the side clips click. The error most people make is populating slots one and three first; use the paired sockets labelled channel A then channel B for dual-channel operation.

What maintenance or replacement will the unbuffered non-ECC kit need over its lifetime?

No scheduled maintenance is required. Keep the interior dust-free so the 1.5 V modules stay cool; they have no heat spreaders. If a stick fails, the limited lifetime warranty from Computer Memory Solutions covers replacement. Beyond a defective module, nothing wears out that needs routine service.

At what point does the CL9 1333 MHz timing become the bottleneck during sustained workloads?

The 9-9-9 latency at 1333 MHz limits sustained bandwidth to the PC3-10600 ceiling. In long renders or heavy multitasking the memory controller hits that throughput wall before CPU or storage does, so frame-times or compile times stop improving even if other components are faster.
