Viper Elite II DDR4 4000MHz Kit Review

Testing Hardware:

• Asus ROG Strix Z490-I Gaming
• Intel Core i9-10900K
• Kingston KC2000 1TB
• 16GB (2x 8GB) Viper Elite II 4000MHz

Testing Software:

• Microsoft Windows 10 Professional 21H1
• Thaiphoon Burner
• CPU-Z
• AIDA64 Extreme Edition
• Passmark Performance Test 10
• SiSoft Sandra

CPU-Z is a freeware that gathers information on some of the main devices of your system:

• Processor name and number, codename, process, package, cache levels.
• Mainboard and chipset.
• Memory type, size, timings, and module specifications (SPD).
• Real-time measurement of each core’s internal frequency, memory frequency.

CPUz shows us we have two XMP profiles available, one at 3600MHz effective at 20-26-26-46 and the spec’d 4000MHz effective with the same timings that we are running for our testing.

Thaiphoon Burner

Thaiphoon Burner is the number one solution on the software market to work with SPD firmware of DRAM modules of PC. Thaiphoon Burner provides powerful features for reading, modifying, updating, and reprogramming SPD firmware of SPD EEPROM devices. The program fully supports all popular JEDEC standards for Serial Presence Detects and third-party enhancements, such as NVIDIA EPP and Intel XMP. Comparing to other software Thaiphoon Burner creates the most completed reports for any of the following SDRAM types of DIMM modules: PC SDRAM, DDR SDRAM, DDR2 SDRAM, DDR3 SDRAM, DDR2 FB-DIMM, DDR4 SDRAM, LPDDR3, and LPDDR4. This is achieved due to the universal built-in SPD decoding engine.

Thaiphoon shows us Patriot is utilizing 8x Hynix DRAM modules but it doesn’t read exactly what series. Based on our testing, We believe it to be CJR series dies.

Here is the full readout if you want to look deep into the specs.

AIDA64 Engineer Edition

“AIDA64 Engineer has a hardware detection engine unrivaled in its class. It provides detailed information about installed software and offers diagnostic functions and support for overclocking. As it is monitoring sensors in real-time, it can gather accurate voltage, temperature, and fan speed readings, while its diagnostic functions help detect and prevent hardware issues. It also offers a couple of benchmarks for measuring the performance of individual hardware components or the whole system. It is compatible with all 32-bit and 64-bit Windows editions, including Windows 10 and Windows Server 2016.”

Viper’s Elite II modules run at 4000Mhz effective and provide around 56GB/s writes and 51.4GB/s on reads. Reads seem a bit slow due to the C20 latency but overall land around what we expect.

The C20-26-26-46 timings hurt latency a bit here, but still provide a decent response time.

Passmark Performance Test – Memory Mark – Threaded

“Fast, easy to use, PC speed testing, and benchmarking. PassMark Performance Test 10 allows you to objectively benchmark a PC using a variety of different speed tests and compare the results to other computers.”

Passmark really likes bandwidth which is mostly a function of speed so the Elite II kit does ok here, but the C20 latency seems to hurt a bit.

SiSoft Sandra

“SiSoftware Sandra provides a robust package of diagnostic tools for testing your system and teasing out its problems–or potential headaches.”

SiSoft aggregate memory scores land at 44GB/s exactly which is pretty close to expected here.
