Pros & Cons
Pros
- ✓ Low-density 256x8 chips that the Dell Optiplex 780 requires
- ✓ Dual voltage: runs at 1.35V (DDR3L) or 1.5V (DDR3)
- ✓ Four 4GB sticks fill all four slots for a 16GB total
- ✓ Standard 1333MHz PC3-10600 at CL9 timings
- ✓ Lifetime warranty from purchase date plus free tech support
Cons
- ✗ 1333MHz is slower than 1600MHz DDR3 for boards that support it
- ✗ Desktop 240-pin DIMMs only, not for laptops (SO-DIMM)
- ✗ Non-ECC, so not suited to servers that require ECC memory
- ✗ 4GB per module limits future upgrades on 2-slot boards
Manufacturer description
Bring an aging Dell Optiplex 780 back to life with the Timetec 16GB kit, four 4GB DDR3 / DDR3L modules rated at 1333MHz (PC3-10600). Each 240-pin stick is non-ECC unbuffered and dual rank (2Rx8). The modules use low-density 256x8 chips, which systems like the Optiplex 780 Desktop, Mini Tower and Small Form Factor require. High-density DDR3 often goes unrecognized in those boards. This kit is built for them. The modules run at either 1.35V or the standard 1.5V, so they work in boards that expect DDR3 and in boards that support low-voltage DDR3L. Timings are CL9, the JEDEC standard for 1333MHz…
SpecPicks Verdict
SpecPicks scored Timetec 16GB KIT (4x4GB) DDR3 / DDR3L 1333MHz PC3-10600 Non ECC… using a rating × review-volume × price-fit model applied to published specs and reviews across the memory & ram category. Timetec's memory & ram lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for memory & ram of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Will this RAM work in my Dell Optiplex 780 SFF?
Yes. Timetec lists the Optiplex 780 Small Form Factor, Desktop and Mini Tower as compatible. All three require low-density memory, which this 256x8-based kit provides.
Can I use this kit in a laptop?
No. These are 240-pin desktop DIMMs. Timetec states the kit is for desktop computers and not for laptops, which use smaller SO-DIMM modules.
Does it run at 1.35V or 1.5V?
Both. The modules are dual-voltage DDR3/DDR3L and run at the JEDEC 1.35V low-voltage spec or the standard 1.5V, depending on what your motherboard supplies.
Is this ECC or registered memory?
Neither. The modules are non-ECC unbuffered (UDIMM), dual rank 2Rx8. They suit consumer and office desktops, not servers that require ECC or registered DIMMs.
What warranty does the Timetec kit include?
Timetec offers a lifetime warranty from the purchase date plus free technical support. You can also contact them with your motherboard make and model to confirm compatibility.
