Patriot Viper Steel DDR4 4000 MHz CL19

A (2x8GB) 4000 MHz Viper kit, is it an actually a steal?

Today we are reviewing Patriot Viper Steel DDR4 memory. This is a new variant of the Patriot Viper series, which quite surprisingly doesn’t have RGB support (unlike the Viper Gaming RGB kit that we checked out previously). I’m not saying that there’s anything wrong with that, as not everyone likes lighting in their PC. The set from Patriot that we reviewed last time was rated at 3200 MHz, and now we’re looking at something much faster. 4000 MHz does sound impressive, doesn’t it? But that’s not all. In this series, you’ll find memory as fast as 4400 MHz!

The kit that arrived consists of two 8GB 4000 MHz DDR4 modules. It’s one of many variants of this series. The other available options are listed below (and some new ones will come at the beginning of 2019):

8 GB 3000 MHz (single module)
16 GB 3200 MHz KIT
16 GB 3866 MHz KIT
16 GB 4000 MHz KIT (the one reviewed here)
16 GB 4133 MHz KIT
16 GB 4400 MHz KIT

Besides the first two models, the range looks very promising and overclocking-friendly because, according to the manufacturer’s info, it’s supposed to be based on Samsung’s B-Die memory chips.


SPEED	LATENCY	VOLTAGE	BANDWIDTH	Capacity
DDR4-3000	15-19-19-39	1.35V	PC4-24000	1 x 8 GB (8GB)
DDR4-3200	16-18-18-36	1.35V	PC4-25600	2 x 8 GB (16GB)
DDR4-3866	18-22-22-40	1.35V	PC4-30900	2 x 8 GB (16GB)
DDR4-4000	19-19-19-39	1.35V	PC4-32000	2 x 8 GB (16GB)
DDR4-4133	19-21-21-41	1.35V	PC4-33000	2 x 8 GB (16GB)
DDR4-4400	19-19-19-39	1.45V	PC4-35200	2 x 8 GB (16GB)

The kit that we’ve received is not the fastest one in the Steel Viper series, but we are still going to try to squeeze something more from it (maybe even reach 4400 MHz?). Of course, you can always stay on the safe side and stick to the advertised frequency and latencies using the Intel XMP 2.0 memory profile. No QVL list has been provided as of yet. The memory is optimized for use with the latest Intel motherboards and processors, but there shouldn’t be any problem with AMD systems either. For our test, Patriot supplied a dual (2 x 8GB) gold DDR4 kit rated at 4000 MHz with CL19, which is ideal for a Z370/Z390 system (dual-channel).

Patriot Viper Steel RGB 3600 MHz (2x 16GB) review
Today, we are looking at Patriot Viper Steel RGB 3600 MHz CL20 (yes – 20!) memory in a 32 GB set consisting of two 16 GB modules. I can say that we’ve had our fair share of experience with Patriot RAM. We had an opportunity to test a similarly clocked kit (3600 MHz) from the Viper Steel series (so no RGB there), but the capacity was 2 x 32 GB back then, and the latencies were quite surprisingly better, at 18-22-22-42. Before that, we also reviewed one of the fastest 2 x 8 GB kits in the range, clocked at 4000 MHz with CL19 latency.

Patriot Viper Steel DDR4 3600 MHz (64GB) review
Today, we are looking at Patriot Viper Steel 3600 MHz CL18 memory in a 64 GB set consisting of two 32 GB modules. At the beginning of 2019, we had an opportunity to check a higher-clocked kit from that series (4000 MHz), but the capacity was 2 x 8 GB. Patriot’s Viper Steel Series is offered at speeds ranging from 3000 MHz up to 4400 MHz, with XMP 2.0 support.
