Pros & Cons
Pros
- ✓ Dual voltage: runs at 1.5V on DDR3 boards or 1.35V on DDR3L
- ✓ Low-density 2Rx8 dual rank works on older boards that reject high-density
- ✓ Lifetime warranty from purchase date with US-based tech support
- ✓ Matched 2x4GB kit avoids mixing mismatched single sticks
Cons
- ✗ 1333MHz PC3-10600 is the slow end of DDR3 speeds
- ✗ CL9 latency is looser than CL7 or CL8 enthusiast DDR3
- ✗ Desktop 240-pin UDIMM only, will not fit any laptop
- ✗ PCB color varies between black and green by production batch
Manufacturer description
Each module runs at 1333MHz PC3-10600 with CL9 timings in a 2Rx8 dual-rank, low-density configuration, which matters if you are reviving an older Core 2, first-gen Core i-series, or AM3 board that rejects high-density chips. The dual-voltage design is the practical win here: the same stick operates at 1.5V on legacy DDR3 boards or drops to 1.35V on DDR3L platforms, so you do not have to guess which spec your motherboard wants before ordering. The modules are non-ECC and unbuffered, matching what consumer desktop chipsets expect from Intel and AMD alike. Timetec backs the kit with a lifetime…
SpecPicks Verdict
SpecPicks scored Timetec 8GB KIT(2x4GB) 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 work in a laptop?
No. These are 240-pin UDIMM desktop modules. Timetec states the kit is for DDR3 desktops with Intel or AMD CPUs, not for laptops, which use 204-pin SO-DIMMs.
Is this DDR3 or DDR3L?
Both. The modules are dual voltage and meet the JEDEC 1.35V standard, so they operate at either 1.35V on DDR3L boards or 1.5V on standard DDR3 boards.
What is low density and why does it matter?
Low density refers to the 2Rx8 dual-rank, 256x8 chip layout. Many older DDR3 motherboards only post with low-density modules, so this configuration improves compatibility with legacy boards.
What warranty comes with these modules?
Timetec lists a guaranteed lifetime warranty from the purchase date, plus free technical support based in the United States.
Why is the PCB a different color than pictured?
Timetec notes the PCB may arrive black or green depending on the production batch. Both colors are the same part with the same 1333MHz CL9 specification.
