This was seen with both AMD and Intel processors.
It boils down to how the memory is configured, or rather the memory “rank.”
However, that’s not always the case.
So when using two single ranked modules for dual-channel operation, the memory is configured as a single rank.
Hitman 2 is another CPU/memory sensitive game, and we’re looking to be GPU bound with the5900X.
Let’s focus on the 1% low data for our comparisons.
With the 3900X we’re looking at an 8% performance increase with 4 sticks.
But again we suspect we’re running into a GPU limitation for the average frame rate.
This configuration will be tested at DDR4-4000, 3800, 3600, and an underclocked 3000 config.
This time we’re seeing a ~5% performance delta between the fastest and slowest memory configurations tested.
Therefore F1 2020 is another game that isn’t particularly sensitive to memory performance.
There’s also little to no difference between single and dual rank memory configurations.
Another game that isn’t heavily influenced by memory performance is Rainbow Six Siege.
Here we’re looking at less than a 2% change between the top and bottom configurations tested.
Memory performance makes a reasonable difference in Watch Dogs Legion.
We’re looking at a 6% performance increase by just adding two more DDR4-3200 modules.
Then by overclocking and tuning up, performance was increased by a further 3%.
As seen earlier, Hitman 2 is very memory and CPU sensitive.
Shockingly we’re looking at a ~23% reduction in 1% low performance.
Still, dual rank memory makes a big difference in this title.
It’s also faster than the single ranked DDR4-3600 CL18 configurations.
Beyond that though, we’re not gaining much with the manually tuned DDR4-3600 and 3800 memory.
When compared to our review setup, we’re looking at just a 3% boost on average.

But wait, there’s more.
Right now something like Crucial’sBallistix 16GB DDR4-3600 CL16kit looks great and costs just $75.
Should you want, they will offer a high degree of tunability.
G.Skill also offers anaffordable DDR4-3600 CL16 kitfor around $80.
Chances are, you’ll never spot the difference.
As for the debate regarding2 sticks vs 4 sticks of memory.
There’s nothing new to report since our own test almost a year back.
The performance uplift forZen 3is no different to that ofZen 2orcompeting Intelprocessors.
The margins will also depend on the quality configs used, and of course, the hardware.
