HP Pavilion Slimline upgrade kit

This 16 GB kit uses two 8 GB DDR3 modules built for the HP Pavilion Slimline S5-1246La, 455-012D and 450-A30 desktops. It adds 16 GB across the two available sockets so the system reaches its maximum supported memory. Non-ECC unbuffered DIMMs keep installation straightforward for a standard office or home PC. The 240-pin form factor matches the board layout exactly.

Sustained load behaviour

Running at 1600 MHz with CL11 timing and 1.5 V, the modules deliver steady throughput during long work sessions or background tasks. The 11-11-11 timings and 2Rx8 organisation help maintain consistent bandwidth without voltage scaling. Unbuffered operation avoids the extra latency step of registered memory. Heat spreaders are not fitted, so airflow in the slim chassis handles cooling.

Build and daily use

Each stick is a standard 240-pin DDR3 DIMM using major-brand chipsets and carries a limited lifetime warranty from Computer Memory Solutions. The two-piece kit fills both slots for dual-channel operation where the board supports it. Product appearance may vary from the reference image. Compatibility is guaranteed for the listed Pavilion Slimline models only.

Questions about this item

How much power does this 16GB DDR3 kit draw at its rated 1.5V speed?

Each module runs at the standard 1.5V DDR3 voltage, so the pair draws only the normal power for two unbuffered 8GB sticks at 1600MHz.

What motherboard slot does this 240-pin DDR3 memory need to fit?

It requires a standard desktop DDR3 DIMM slot — 240 pins — and the system must accept non-ECC unbuffered modules.

Will these CL11 1600MHz sticks run reliably in the two-slot HP Pavilion Slimline S5-1246La?

Yes, the kit is validated for that exact model and its two DIMM sockets, so both 8GB modules will operate at the rated 1600MHz CL11 timing.
