Be wary of "selling for cheap". Products could be faulty, counterfeit, going obsolete.
And depending on the computer itself, over-clocking may or may not gain anything. There are other considerations involved.

Update your post to include full system hardware specs and OS information.
Include PSU: make, model, wattage, age, condition?
Disk drive(s): make, model, capacity, how full?
You need to go back a couple of steps.
First go online and find the applicable User Guide/Manual for your computer's motherboard.
The User Guide should provide detailed information regarding supported RAM and supported RAM configurations. Over-clocking options being part of that.
The User Guide will also likely refer you back to the motherboard's manufacturer's website for more up-to-date information. Do so and double check everything. Details matter.
For example: the QVL (Qualified Vendors List) for supported components such as RAM. What is and is not supported. Mixed RAM may work but only at the speed of the slowest supported module(s).
In many cases, you need a matched pair of RAM modules to ensure dual channel support. Other unmatched RAM combinations may or may not work.
Or simply be problematic with negative impact on reliability and/or performance.
