DDR5 memory nowadays is way more mature compared to how it used to be back in late 2021 when was first introduced to the consumer market alongside the 12th-gen Intel Core processors and 600 series chipset motherboards. As of today, we’re seeing DDR5 memory that is not only significantly cheaper but also kits that come with an XMP profile that goes up to DDR5-8400 or 8400MT/s. We won’t be looking at DDR5 memory kits with profiles that go up to 8000MT/s+ this time but rather, a DDR5 memory kit that is made ready with both Intel XMP and AMD EXPO profiles – the KLEVV CRAS V RGB DDR5-6000 32GB CL30.

Unboxing
The KLEVV CRAS V RGB DDR5 ships in standard packaging which you can expect to see for most of the DDR5 memory kit nowadays. Around the box, you’ll find information such as the speed and capacity of the kit, the AMD EXPO and Intel XMP certification, and RGB software which can be used to sync the RGB lighting on the kit to the motherboards that is on the supported list.
Design-wise, the kit comes with two different color variants of obsidian black and brilliant white that fit the requirements of most system builders nowadays. Despite not being as fancy as the CRAS XR5 in terms of design, I find the design of the CRAS V RGB DDR5 goes very well with the newer motherboards.
Although KLEVV is known to rebrand the memory chips they used on their kits, we can tell that they’re SK Hynix A die based on the specs, which is renowned for its excellent overclocking headroom when paired with a good motherboard and CPU with a strong IMC.

Memory Overview
Even though the manufacturers offer settings for both Intel and AMD systems (XMP and EXPO), they often play it safe by using slower speeds than the memory might be capable of. This ensures the RAM works well on most computers. If you’re comfortable making adjustments, some DDR5 kits can be overclocked for better performance. How far you can push the memory frequency will depend on the quality of the memory chips used aside from the CPU and motherboard you’re using.
For this test, we’re using an AMD X670E chipset motherboard because most DDR5 memory kits with Hynix A die we’ve tested so far can easily go more than DDR5-7600+ on an Intel Z790 chipset motherboard. Also, since AMD has put in a lot of effort on the AGESA update which allows DDR5 memory kits to finally able to go beyond DDR5-6400, we thought of giving it a try just for the fun of it.
With the EXPO profile enabled, the kit will run at DDR5-6000 CL30-36-36-76 and it’s already better than older DDR5-4800 kits and some of the newer DDR5-5600 kits out there. If you’re not feeling that adventurous but somehow still want to optimize a bit for slightly better performance, you can adjust the value of the following:
- tRFC to somewhere around 380
- tRAS to 30
- tRRDS to 4
- tRRDL to 6
- tRTP to 12
- tFAW to 16
- tCWL to 30
- leave the rest on auto
If you’re one of the early adopters of AMD Ryzen 7000 series desktop processors, you’ll notice that DDR5-6400 can be difficult to achieve and you’ll need a reasonably good X670E motherboard and CPU to achieve that. With the newer AGESA update, DDR5-6400 is very easy to achieve now and you don’t need to bump up the voltage much if you’re not going for really tight timings.
For our case, we got the kit running at DDR5-6400 CL32 with very minimal adjustments – sub timings remain the same as our DDR5-6000 CL28 settings, primary timings increased to CL32-38-38-30 and DRAM voltage at 1.43V. Performance gain might not be that significant for basic usage such as internet browsing and office work, but you will notice a better 1% low in games.
And just for the fun of it, we gave DDR5-7200 a try and it didn’t take too much effort to get it running stable at this speed but you will need to bump up the DRAM voltage to about 1.46V. You will need to have a reasonable cooling solution around the DIMM slots area because the kits will need some proper cooling to ensure the system is running stable at all times if you’re running at this speed.
Final Thoughts
Similar to many Hynix A-die kits we’ve tested, the KLEVV CRAS V RGB DDR5-6000 shows promising potential for overclocking on both Intel and AMD platforms. At the price of RM 629, the KLEVV CRAS V RGB DDR5-6000 is a strong option for those seeking a good DDR5 kit, not just for overclocking but potentially for gaming as well.
Even if you’re not aiming for super-high speeds, tightening the timings from the XMP profile is easier compared to some earlier DDR5 kits. This is a good thing, but keep in mind that results may vary depending on your motherboard and the quality of the memory controller (IMC).
For those who are already rocking with the best motherboard and CPU they can get and just want the best DDR5 memory kit out of the box instead of going through the pain of finding the best settings, the KLEVV CRAS V RGB DDR5 does come with models that have a higher rated speed at DDR5-8000+ but that will come at a higher price if you manage to find it.
