Easy Overclocking with a Single Click and Futuristic RGB Lighting Strip | Unveiling the KLEVV CRAS V RGB DDR5 7600MT/s 32GB Kit (2x16GB)
When DDR5 memory first hit the market, standard JEDEC frequencies were set at 4800MT/s, 5200MT/s, and 5600MT/s, with the 6000MT/s and 6400MT/s variants being the premium, high-end options. However, this year has seen a surge in the availability of high-frequency memory modules. For instance, the KLEVV CRAS V RGB DDR5 memory unveiled recently starts at what has now become the standard base frequency of 6000MT/s and soars to an impressive peak of 8000MT/s. Achieving such high speeds necessitates close collaboration with motherboard producers. KLEVV has partnered with the leading motherboard brands — ASUS, ASRock, Gigabyte, and MSI — and has conducted thorough QVL (Qualified Vendor List) tests to guarantee compatibility.
A standout feature of the KLEVV CRAS V RGB DDR5 memory is its 2mm-thick aluminum heat sink, designed to ensure efficient heat dissipation. The memory features a matching color scheme and a rectangular fin design that showcases the RGB lighting from both the sides and top, offering vivid illumination. It also supports the lighting synchronization software from these top motherboard manufacturers, allowing users to customize their setup’s aesthetic easily.
To reach such extreme frequencies, the KLEVV CRAS V RGB DDR5 memory utilizes a 10-layer PCB equipped with a PMIC (Power Management Integrated Circuit) to enhance power stability. It also incorporates On-die ECC (Error-Correcting Code) for reliable operation. Compatibility with Intel’s XMP 3.0 and AMD’s EXPO technologies facilitates simple one-click overclocking, streamlining user performance optimization.
The CRAS V RGB DDR5 memory is compatible with the RGB lighting synchronization software from the four major manufacturers, enabling users to customize lighting effects to their preferences. With a heat sink included, its height is 44mm, aligning with the standard size for mainstream RGB memory, ensuring compatibility with the majority of air-cooling systems.
KLEVV CRAS V RGB DDR5 7600MT/s 16GBx2 Memory Performance Test
For this memory evaluation, we utilized an Intel i9-13900K and a ROG MAXIMUS Z790 HERO motherboard to assess JEDEC standard frequencies, XMP (Extreme Memory Profile) overclocking capabilities, and manual overclocking potential, with the Memory Controller set to a DRAM ratio of 1:2. All other motherboard configurations were left on Auto.
It should be noted that DDR5 motherboards released earlier may not support such elevated frequencies. Before installation, it’s crucial to verify that the memory has passed the QVL (Qualified Vendor List) tests for your motherboard and to ensure that the BIOS is updated to the latest version. This is to secure optimal stability and performance for the system.
- CPU: Intel Core i9-13900K
- Motherboard: ROG MAXIMUS Z790 HERO (BIOS Version: 1303)
- Cooling System: ROG RYUJIN II 360
- Operating System: Windows 11 Professional Edition, version 21H2
- Power Supply Unit: Seasonic Focus 1000W
BIOS SPD (Serial Presence Detect) data reveals that the CRAS V RGB DDR5 7600MT/s 32GB (2x16GB) utilizes SK Hynix memory chips. The JEDEC default clock is configured to 4800MT/s with timings of 40-40-40-77-117 at 1.1V. The XMP (Extreme Memory Profile) is set to run at 7600MT/s with timings of 36-46-46-86-132 at a voltage of 1.4V.
Initially, we conducted tests using the standard JEDEC frequency, which means that XMP (Extreme Memory Profile) was not enabled. The results from the AIDA64 memory and cache benchmark were as follows:
- Read Speed: 75,673 MB/s
- Write Speed: 68,637 MB/s
- Copy Speed: 68,106 MB/s
- Latency: 89.7 nanoseconds
With XMP activated, the memory frequency is elevated to 7600MT/s. The AIDA64 cache and memory benchmark results under these conditions are:
- Read Speed: 113.45 GB/s
- Write Speed: 97,643 MB/s
- Copy Speed: 100.26 GB/s
- Latency: 64.8 nanoseconds
The read and write speeds showcase an improvement of approximately 50%, which is a substantial difference. It’s essential for buyers of high-frequency memory to enable XMP to fully utilize the memory’s capabilities; failing to do so would mean not taking advantage of the significant performance gains available.
After experimenting with manual overclocking, it’s apparent that 7600MT/s is already pushing the boundaries of this particular motherboard. The integrated memory overclocking parameters provided by ROG cap out at 7600MT/s. Nonetheless, aiming to push the limits, the voltage was increased to 1.45V and the timing was adjusted to CL40-48-48-128, which resulted in a successful system boot and completion of all tests.
The AIDA64 cache and memory benchmark under these overclocked settings showed:
- Read Speed: 116.83 GB/s
- Write Speed: 99,278 MB/s
- Copy Speed: 100.65 GB/s
- Latency: 65.4 nanoseconds
This represents a modest performance enhancement. It highlights the potential headroom available in the memory for overclocking enthusiasts, but also underscores the importance of a compatible and capable motherboard when attempting to exceed standard overclocking limits.
Utilizing PerformanceTEST to gauge the memory’s prowess, we examined various metrics including database operations, memory reads with cache on and off, memory writes, latency, as well as the ability to manage memory allocation.
At the XMP frequency of 7600MT/s, the KLEVV CRAS V RGB DDR5 32GB (16GBx2) memory kit attained an overall score of 4223, placing it in the 99th percentile of overall performance rankings. This score indicates that the memory kit outperforms 99% of the systems tested with this application, showcasing its superior performance capabilities when operating at the XMP settings.
In the final evaluation phase, Prime95’s Large FFTs test was utilized to stress the system, running for 30 minutes using the memory’s 7600MT/s XMP settings. The memory operated with commendable stability throughout this intensive stress test. On an open-air test platform, the peak temperature recorded at the memory’s SPD Hub reached 63.8 degrees Celsius, while the average temperature maintained a relatively cool range of 48 to 49 degrees Celsius. These temperatures indicate that the memory maintained efficient thermal performance even under heavy load, a testament to its robust cooling solution.
The KLEVV CRAS V RGB DDR5 memory blends gaming and technological aesthetics seamlessly. It boasts elegant aluminum heat sinks and proportionate RGB light bars that create a sophisticated texture with its tone-on-tone design. The memory sticks are crafted to a standard height of 44mm, ensuring broad compatibility with various computer builds and effective heat dissipation. This memory supports one-click overclocking technologies such as Intel XMP 3.0 and AMD EXPO, offering a range of frequencies from the entry-level 6000MT/s to the high-end 8000MT/s. This caters to gamers with different budgetary considerations and performance needs, offering a spectrum of options.
Having successfully undergone QVL testing with major motherboard manufacturers, the memory guarantees reliability and stability. The officially listed price for the 7600MT/s variant is $145 USD. Achieving higher frequencies would place significant demands on the CPU, motherboard, and memory. Thus, while gamers with more substantial budgets might opt for top-tier configurations straight away, those with a penchant for DIY approaches may consider starting with lower base frequencies and manually overclocking to maximize cost-effectiveness and performance gains.
