Quite different controllers, I wouldn't mix them although they just might work together. You wouldn't know until you try.I currently have a 8gb 2133mhz valueram ram and im plannig to add more ram with the same speed and capacity but with a different model such as the hyperx fury
should buy the same model as im using right now or is ok to buy a different model?
What motherboard do you have?
Is that 8 GB RAM one module, two modules, 4 modules?
The starting point is to determine what RAM modules are supported by the motherboard and in what combinations.
For the most part you should purchase identical modules that are tested and packed as a kit to be used together.
Another thing to do is to go to the various RAM manufacturer's site and use any provided configuration tools.
You can either enter in information about your computer (usually the motherboard) or download a utility that will scan the computer and identify the applicable RAM and possible installation combinations.
Details matter so always try to find a consensus with respect to the RAM module(s) and specs applicable to your motherboard.
Post what you learn and believe to be workable. Hopefully someone will be able to validate your choice(s).

Does the following link match the RAM 2 x 16GB kit you intend to buy?
https://www.amazon.com/HyperX-2666M...la-824476733911&ref=&adgrpid=82240853001&th=1
If so, the RAM should work. Do verify by checking specs and installation instructions per the motherboard's User Guide/Manual. Read the fine print.
so its better to buy a new 2x 8gb instead of buying one stick first and add the other later?So what that tells me is that you have a single 8 GB module now and plan to add a second 8 GB module to increase total RAM to 16GB - correct?
Buying a matched kit of 2 X 8GB modules is my recommendation.
