Performance surpasses 98Gbps! Unboxing test for the KLEVV CRAS XR5 RGB DDR5 6200MT/s 16Gx2 memory: stunning, exceptional performance

In the past six months, due to the support of Intel and AMD, DDR5 memory has gradually become popular, and the price has gradually dropped to a balance point that players can accept. With the launch of new platforms, the frequency and delay of DDR5 memory are also improving. From South Korea, The well-known memory brand KLEVV launched the CRAS XR5 RGB DDR5 dual-channel memory set, which has a capacity option of 32GB (16GBx2) and provides two frequency options of 6200MT/s and 6000MT/s. After turning on XMP 3.0 overclocking to After 6200MT/s, it can break through the high-speed performance of memory reading 95Gbps, and at the same time, it has RGB lighting effects and a super high-quality design.

Intel and AMD have officially pushed PCs to the DDR5 generation. KLEVV has also updated its own high-performance DDR5 product line. Following the standard U-DIMM/SO-DIMM products, it also launched a built-in heat sink and RGB lights. The CRAS XR5 RGB DDR5 memory has a frequency of up to 6200MT/s and XMP 3.0 overclocking support.

In terms of capacity, CRAS XR5 RGB memory currently only offers 16GBx2 (32GB) dual-channel sets. With the increasing demand for high-end software and the upgrading of computer hardware specifications, the single capacity of DDR5 memory is 16GB. It is already the market demand standard.

CRAS XR5 RGB comes with its own RGB ring-shaped light guide light bar and supports five brands of lighting control software, including four major motherboard brands, MSI, ASRock, GIGABYTE, ASUS, and peripheral gaming manufacturer Razer. Players can use the software to synchronize hardware lighting effects.

Support MSI, ASRock, GIGABYTE, ASUS, Razer lighting control software, and Intel XMP 3.0 one-key overclocking technology.

In terms of appearance, the heat sink made of KLEVV CRAS XR5 RGB white aluminum can effectively dissipate the heat generated by the memory particles and the PMIC power control chip, thereby bringing good heat dissipation performance and improving cooling efficiency.

The heat dissipation armor of CRAS XR5 RGB is divided into three design layers. The surface of the largest white block has many circular grooves. The golf ball-like texture on the heat sink can increase the heat dissipation surface area to improve the heat dissipation performance of the armor itself. The second layer, The black block, is coated with piano lacquer, and the words KLEVV CRAS XR5 RGB and DDR5 are printed on it, which greatly improves the overall texture.

A product label on the back of the memory lists the frequency, timing, voltage, single capacity, and the most important product model after XMP3.0 is turned on. When querying the memory QVL support list of each motherboard will be required for verification.

KLEVV CRAS XR5 RGB has a unique ring-shaped light guide light bar on the top of the memory. This appearance continues the characteristics of CRAS XR RGB DDR4 memory and retains the classic design of the new generation of DDR5 products. The corner light guide strip gives the 16.8 million-color RGB lighting effect a more vivid color performance.

The top adopts a ring-shaped light strip, a semi-transparent material when it is not powered on.
KLEVV CRAS XR5 RGB actual lighting effect display has a very unique shape.

KLEVV CRAS XR5 RGB uses a single-sided particle configuration, a total of eight SK Hynix memory particles with a capacity of 2GB. One of the biggest differences between DDR5 memory and the previous DDR4 memory is the integration of PMIC (power management chip) into the memory. It is different from the previous scheme of setting it on the motherboard, which can make the memory have better efficient in power management and more stable power supply capability.

DDR5 memory also adopts the new ODECC (On-die ECC error correction technology), which provides error detection and correction functions, allowing players to have a more stable operating experience while pursuing performance.

The mounting pins are DDR5 288 Pin, and the fool-proof hole is different from the previous DDR4. If it cannot be installed, please do not install it hard.

KLEVV CRAS XR5 RGB DDR5 6200MT/s 16Gx2 memory performance test

First, check the relevant information by CPU-Z. On the SPD page, you can see that KLEVV CRAS XR5 RGB has three JEDEC values ​​and one set of XMP 3.0 values. The JEDEC clock and timing in the BIOS default state are 4800MT/s CL40 -40-40-76, use SK Hynix memory particles and support the latest Intel XMP 3.0 one-key overclocking technology.

The test platform this time uses the Intel 12th generation platform that supports DDR5 memory and XMP 3.0, uses ASRock Z690 Taichi Razer Edition and i9-12900K to test KLEVV CRAS XR5 RGB DDR5 6200MT/s 16Gx2, and test the preset JEDEC 4800MT/s, XMP 3.0 6200MT/s, and overclocking to 6400MT/s and 6600MT/s, how about the read and write performance at the four speeds.

Overview of CPU-Z information.
Enable XMP 3.0 overclocking in the BIOS, and set the file to 6200MT/s CL 40-42-42-78 voltage 1.3V.

Test Platform
Processor: Intel Core i9-12900K
Motherboard: ASRock Z690 Taichi Razer Edition
Memory: KLEVV CRAS XR5 RGB DDR5 6200MT/s 16Gx2
Display Card: NVIDIA GeForce RTX 2080 Super
Operating System: Windows 11 Home Edition 21H2

The JEDEC default clock of KLEVV CRAS XR5 RGB is 4800MT/s CL40-40-40-76, using AIDA 64 to test read and write as 74356MB/s, 68802MB/s, copy as 67916MB/s, and delay as 85.4ns.

After enabling Intel XMP 3.0 one-key overclocking, the XMP profile is 6200MT/s CL 40-42-42-78 voltage 1.3V, using AIDA64 to test read and write as 95004MB/s, 85596MB/s, copy as 86244MB/s, delay It is 69.3ns.

Without changing the voltage and timing settings, it can be directly overclocked to 6400MT/s. At the same time, the memory read and write performance is improved to 96844MB/s, 86948MB/s, the copy is 87804MB/s, and the delay is 70.9ns.

If you want a higher frequency of 6600MT/s, you can achieve it by manually adjusting the timing. Manually overclock to 6600MT/s CL 34-40-40-84 voltage Auto. The test results are read and written: 98246MB/s, 90818MB/s, copy 88319MB/s, delay: 66.7ns. If the frequency is higher than 6600MT/s, it cannot pass the self-test program with the setting of CL34. If you want to run at a higher clock speed, you can manually adjust other parameter settings and try to see different parameters. There is still a good chance of running at frequencies over 6600MT/s.

Then, test the pressure stability of the memory through AIDA64 System Memory. The test set is memory XMP 3.0 overclocking parameters 6200MT/s CL 40-42-42-78 voltage 1.3V.

On the naked test platform without a fan blowing directly on the memory, the temperature of the SPD Hub reached a maximum of 47.5°C after 15 minutes of testing, and the temperature performance is quite good! In the situation where players install and use the computer, fan airflow will help the memory dissipate heat, so the actual use environment temperature will be lower.

AIDA64 system memory temperature test, bare test with fanless direct blowing test platform SPD Hub up to 47.5°C.



KLEVV CRAS XR5 RGB memory has a unique styling style. The ring-shaped RGB light bar design on the top makes it look like a double beam when installed and looked down. The snow-white aluminum heat dissipation armor provides sufficient heat dissipation performance for the memory particles and the PMIC power management chip. It also has a good temperature performance in the AIDA64 System Memory test. Let CRAS XR5 RGB have a very high texture score overall.

The memory particles use DDR5 contemporary most acclaimed SK Hynix M die particles, so CRAS XR5 RGB will also have a good overclocking performance. After adjusting the parameters in this test, the frequency can reach 6600MT/s and break through the reading speed of 98Gbps. For write performance, players who like extreme memory overclocking can manually adjust the parameters and voltage to obtain better read and write performance and latency performance.

With the gradual popularization of DDR5 becoming mainstream, if you are looking for a memory card with good read-and-write performance and a simple style in appearance, you can refer to this KLEVV CRAS XR5 RGB DDR5 memory.
