A guide to digital inspiration
Foreword:
The pursuit of computer performance and the ability of machines to play a better role are the basic requirements of productivity. For computers, in addition to the basic board is better, the performance of memory has always been the main concern of ordinary users and gamers. For the general public, manual overclocking is always a hurdle that cannot be overcome, and various parameter adjustments are really impossible to achieve without real technology, so they can only choose a more expensive high-frequency memory module to turn on automatic overclocking, which is unattainable for manual overclocking and high frequency.
Prologue:
If you happen to belong to the public group who will not manually overclock this article, then this content will definitely make you gain a lot, the author's recent test experience of a set of "KLEVV cras v RGB 6400 DDR5 memory module (16GB*2 suite)", its fool-style (no need to adjust complex parameters) manual overclocking to 7200MHz performance, absolutely let you use the most suitable**, harvest a set of memory with outstanding performance.
xmp 3.0 expo one-click overclocking for dual platforms:
The CRAS V (aka: CRA Yanlong V) 6400 DDR5 memory module (16GB*2) has a tacit frequency of 4800MHz and supports Intel XMP 30 One-click overclocking technology with AMD Expo dual platform, automatic overclocking can be turned on through the BIOS, reaching 6400MHz. At the same time, this series provides 6000MT S, 6400MT S, 7200MT S, 7600MT S, 8000MT S five different speed specifications of the sleeve for us to choose from (recently launched 8200MT S and 8400MT S two styles, and also added a new color of crystal white), if you really can't even adjust the timing and voltage, the preset higher rate (expensive) specifications will be more suitable for you. This time, the author started with the 6400MT S, a set of lower (cheaper) specifications, through fool-like manual overclocking, you can easily achieve a higher rate, and the performance potential far exceeds expectations.
Technical Parameters:
According to the technical annotation of this set of memory modules by KLEVV, the CRAS V RGB black PCB board has up to 10 layers, integrates PMIC (power management chip), temperature sensor, and On-Die ECC error correction technology, which meets the requirements of DDR5 technical specifications. Among them, the 6000mt s and 6400mt s versions have a lower driving voltage, only 135V, 7000MT S, 7200MT S drive voltage is 14V, 8000MTS reached 145V, the power supply requirements for the motherboard are higher.
Test platform:
The test uses the Intel Core i5 13600KF processor and the ASUS B760 F ROG WiFi D5 motherboard, with the 13th generation LNTEL processor, the i5 13600KF processor can be said to be a low-end CPU.
Silent Frequency One-click overclocking performance test:
1. CPU-Z parameters.
From COU-Z, we can see that the silent frequency of COFU CRAS V (6400MTS) is 4800MHz, the timing is 40-40-40-76, and the line period is 116, which is relatively conservative.
Go into BIOS to turn on XMP 30 key overclocking can reach the preset frequency of 6400MHz with a timing of 32-38-38-78, with a lower timing, the line cycle is still 116.
2. AIDA64 performance test.
Tested separately on the AIDA 64 tool at 4800MHz, 4800MHz was 70042 MB s read, 67732MB s write, and 901ns；
The 6400MHz has a read of 92,220 Mb s, a write of 85,846 Mb S, and a latency of 705ns, compared to 4800MHz data, the read is increased to 13166%, write increased to 12673%, and the latency is reduced to 78 of the silent frequency24%, the bandwidth is greatly improved, and the latency is shorter.
Manual over-pre-pre-order:
About manual overclocking,To say that there is really no technical content, really don't get it.,It's a really torturous job.,It takes countless times to change the parameters-restart the computer-reset the BIOS-in order to catch the really stable frequency point.,It's common to do a bad job or even burn memory or other hardware.,Not to mention the general public.,Personally, I'm rarely going to engage in manual overclocking now.,It's time-consuming and energy-consuming.,It's too torturous.。 However, this time I got this set of Kefu CRAS V memory module, but it gave me a very big surprise, in the state of not changing the small parameters, only changed the timing and voltage, it easily exceeded the frequency of 7200MHz, which is really unexpected.
In the meantime, I slowly overclocked from the base of 6400MHz and slowly worked my way up, increasing the timing and voltage (1.).4V), all the way to 7400MHz, the stability of the boot test is wrong, and finally it is returned to 7200MHz (timing 34-44-44-84, voltage 1.).4v）。
The 7200MHz passed with 0 errors in a variety of memory test tools, which was perfect, and the AIDA64 performance was improved to 10085GB s, write 10432GB s, latency of 663ns, compared to 6400MHz, the read is increased to 11217%, and the write has been increased to 12465%, latency reduced to 94 at 6400MHz04%, with better bandwidth and lower latency.
Stability Test:
At the same time, 7200MHz is available in TestMEM5, TechPowerUp MEMtest64 and more professional RunMEMtestPro 45. Pressure stability test is carried out in these three tools. Among them, TechPowerUp Memtest64 ran 10 laps in cycles, RunMemtestPro 45 burned for nearly 1 hour, the progress reached more than 102%, and the three major tools were all 0 errors, which was perfect.
In addition, a benchmark comparison was performed with 7-zip, and the default frequency compression score of 4800MHz was 114658 gips, decompression score of 128033gips with an overall rating of 121346gips；The compression score for the 7200MHz frequency is 133290 gips, decompression score of 129290gips with an overall rating of 131621gips, a relative increase of 847%。
PCMark 10 Performance Test:
The 7200MHz frequency was used to conduct a multi-comprehensive stress simulation test with PCMARK, including a comprehensive test of office applications, documents, processing power, etc., and obtained a score of 11175 for productivity and 10942 for digital content creation, with a comprehensive score of 7961, which is not bad.
Comparison of memory scores:
Use the entertainment master to compare the running scores of 4800 6400 7200 three rates, respectively263450 351129 397216, 7200MHz Compared with 4800 silent frequency running scores, the running score has increased by 133766, this data has changed very much, and the improvement is particularly obvious.
Summary:
There is no need for more complex small parameter adjustments, just a simple change of timing and voltage, COLEV CRAS V 6400 DDR5 memory module (16GB*2) can reach a rate of 7200MHz, for the general public, manual overclocking is no longer difficult, with 6400MHz **, you can enjoy the performance of 7200MHz specification, which is really great.
Secondly, for my Intel Core i5 13600KF processor and ASUS B760 F ROG WiFi D5 motherboard, it was really good to be able to achieve such results. If combined with the 13th generation i7 i9, the CRAVOS V RGB can also play even better. If you are even willing to toss, with the performance of this set of memory modules, and then adjust the small parameters, manual overclocking to 7800 or even 8000MHz should be no problem for stable use.
Design Style:
The CROS V RGB is mainly black, and is equipped with RGB full color gamut lighting effects, which supports the divine light synchronization (lighting effect management) of common mainstream motherboards, which is also a factor for me to choose it, because my host and board are mainly black, and the memory module used in the early stage is white (given by a friend), which is really discordant, and this time it is perfect.
The CRAVS V RGB body is flanked by aluminum alloy heatsinks with an overall height of 34mm and a thickness of 8mm, which will not affect the installation of air-cooled radiators. Secondly, it covers the 8mm thickness of the heat dissipation vest, and for the motherboard with double card stags, there are also enough heat dissipation and ventilation gaps to ensure the heat dissipation effect of the memory module and ensure stable performance.
In terms of design, the line design of COFU CROS V RGB is not bad, and the RGB full color gamut lighting effect is my favorite, dynamic marquee, static monochrome is very cool, and the ** rhythm of the motherboard can also be synchronized, very nice, you can't dislike it.
Conclusion:
While it's important to have good memory performance and support for overclocking, it's important for the general public to focus on peace of mind and hassle. In this regard, the KLEVV CRAS V RGB series is very good, and it is rare to try to manually overclock to 7200MHz at 6400MHz without adjusting the small ginseng and can be used stably. Secondly, one-click overclocking to 6400MHz, which is also very friendly to users who are completely novices, without unnecessary operations, in one step. Secondly, there are 6000MT S, 6400MT S, 7200MT S, 7600MT S, 8000MT S, 8200MT S, 8400MT S (black and white two colors), a variety of rates can be selected on demand, to have performance, to have good looks, and more simplified manual overclocking, KLEVV CAS V RGB series is worth having.
