HP ENVY 700 DDR3 Upgrade

This 4GB DDR3 1600 CL11 UDIMM is built specifically for HP ENVY 700 Series desktops that use DDR3 memory. It targets owners who need a straightforward capacity increase for everyday multitasking and office workloads.

240-pin 1.5V Non-ECC Module

The single-rank 1Rx8 stick fits a standard 240-pin DDR3 slot and runs at the JEDEC 1.5V specification. No heat spreader is included, so clearance inside compact ENVY chassis is maximised. The unbuffered, non-ECC design matches the platform's native memory controller requirements.

Replaces Slower or Smaller DDR3 DIMMs

Swapping out a lower-frequency module or adding this stick to a free slot raises total bandwidth to PC3-12800. The jump is worthwhile when the system currently runs below 1600 MT/s or has less than 4GB per channel, eliminating a memory bottleneck for general productivity.

Questions about this item

Will the CL11 latency limit bandwidth during sustained workloads?

CL11 is the rated CAS latency for this DDR3 1600 module; it operates at 1.5V and meets JEDEC PC3-12800 timing specifications.

Does the module run hot or draw extra power during all-day operation?

The 1.5V DDR3 UDIMM has no heat spreader and conforms to standard JEDEC power limits for unbuffered desktop memory.

Must the HP ENVY 700 Series already have DDR3 slots free for this 240-pin DIMM to work?

Yes, the system must be an HP ENVY 700 Series desktop that uses DDR3 memory and has an available 240-pin UDIMM slot.
