System Overview & Testing
We installed the Viper Elite II in our Z590 test system and the first thing I noticed was that the stickers on the memory faced out, which was a bit odd. I’m not sure how Patriot overlooked this.
Our test system is made up of the following components.
Processor: Intel Core i9-11900K
Graphics Card: MSI GeForce RTX 3080 Gaming X Trio
Motherboard: Gigabyte Z590 AORUS Master
Memory: Viper II Elite 32GB
Storage: SK hynix Gold P31 M.2 1TB
Power: Corsair AX860i
Cooling: Noctua NH-U12A
Case: Open PC Test Bench
Taking a look at CPU-Z we can see this memory is running at its XMP profile, operating at 4000 MHz with timings of 20-26-26-46 at 1.4V. This kit actually has a second XMP profile that runs the kit at 3600 MHz with the same timings at 1.35V.


For testing we will run the memory at its stock or XMP profile settings using the below benchmarking software. Below is a list of benchmarking software that we use.
– SiSoftware Sandra Memory Bandwidth Benchmark
– SiSoftware Sandra Cache & Memory Latency Benchmark
– SiSoftware Cache Bandwidth Benchmark
– AIDA64 Cache & Memory Benchmark
– 3DMark Fire Strike Physics test
Now let’s get to testing!
To start things off we have SiSoftware’s Sandra. The first test is the Overall Memory benchmark. Higher scores are better here.

Next is the Memory Bandwidth benchmark, higher scores are better here.

Next we have Sandra’s Cache & Memory Latency benchmark that will measure the memory kits latency. Lower scores are better here.

AIDA64 has a built in Cache & Memory benchmark that measures read, write, copy and memory latency. Higher scores are better here.

Finally we wrap things up with 3DMark’s Fire Strike benchmark. We will be taking the Physics score from our benchmark as it will change the most when you change memory speed. Again, higher scores are better here.
