Manufacturer description

Bring an older desktop back up to speed with the Timetec 8GB KIT (2x4GB) DDR3 / DDR3L 1333MHz memory upgrade. Each 240-pin module runs at PC3-10600 speeds with CL9 timings. The kit is listed for the Dell Optiplex 780 in its DT, MT and SFF versions, so it gives that office machine or a budget retro build a simple path to 8GB. These are dual-voltage DIMMs. They meet the JEDEC 1.35V DDR3L standard and also run at the standard 1.5V, so they work on boards that expect either voltage. The modules are non-ECC, unbuffered and dual rank (2Rx8), built on low-density 256x8 chips. Older desktop chipsets…

Frequently Asked Questions

Will this Timetec kit work in my Dell Optiplex 780?

Yes. The kit is listed for the Dell Optiplex 780 in DT, MT and SFF versions. It is 240-pin DDR3 1333MHz PC3-10600 non-ECC unbuffered memory, the module type that desktop uses.

Can I use this RAM in a laptop?

No. These are 240-pin desktop DIMMs, and Timetec states they are for desktop computers, not laptops. Laptops use smaller SO-DIMM modules.

Does it run at 1.35V or 1.5V?

Both. Each module meets the JEDEC 1.35V DDR3L standard and can also run at 1.5V, so it works on boards set to either voltage.

What does low density dual rank mean for compatibility?

Each 4GB module is dual rank (2Rx8) and built on 256x8 chips. Many older desktop chipsets only support this low-density layout and may not detect high-density 4GB DDR3 sticks.

What warranty comes with this memory kit?

Timetec provides a lifetime warranty starting from the purchase date, plus free technical support. Check the product listing for current claim terms.
