Hardware Asylum checked out the GSKill Trident Z 4133Mhz RGB CL19 DDR4 Dual Channel Memory
A quote from the article:
When it comes to performance memory there are a variety of brands to choose from each with different product lines and product offerings with unique frequencies and module timings. Any one of those modules will give you adequate performance in a normal gaming PC however, when it comes to overclocking the list of vendors gets reduced down to a handful.GSKill Trident Z 4133Mhz RGB CL19 DDR4 Dual Channel Memory Review @ Hardware Asylum
In this review I'll be looking at the F4-4133C19D-16GTZR Trident Z memory modules from GSKill. This is a 16GB dual channel DDR4 memory kit running at 4133Mhz with a CAS latency of 19. What is really impressive about these modules is that while they are some of the fastest DDR4 modules you can buy they are also fully RGB enabled with a multi LED light bar across the top of the module.
