4GB DDR3 1600 UDIMM for desktop upgrades

This 4 GB DDR3 1600 module uses the standard 240-pin UDIMM form factor and runs at 1.35 V with CL11 latency. It is built for desktop boards that accept non-ECC unbuffered memory and is validated against the Dell SNPVT8FPC/4G A6994459 part number.

Major OEM chips tested under load

Samsung Micron or Hynix DRAM components are assembled on each stick and then stress tested at full load before shipping. That validation step replaces the usual guesswork when mixing modules and reduces the chance of boot failures or data errors.

1.35 V operating voltage

The module operates at 1.35 V rather than the older 1.5 V DDR3 standard. If your motherboard or BIOS only supports 1.5 V operation this stick may not post or may run at reduced speed so verify the board's voltage capability before purchase.

Questions about this item

Will the 240-pin DDR3 module need any re-seating or cleaning after long-term use?

Standard UDIMM contacts benefit from occasional re-seating to clear oxidation; no moving parts or heat spreader mean no scheduled replacement is required.

What limit appears first when the CL11 1600 MT/s stick runs sustained workloads?

The single 4 GB capacity caps multitasking headroom before the CL11 latency or 1.35 V operation becomes a bottleneck.

How much heat or fan noise does the unbuffered 1.35 V module add during all-day operation?

Low 1.35 V draw and no heat spreader keep thermal output minimal; it adds virtually no audible noise to a typical desktop chassis.
