The Cras V RGB DDR5-9600 C46 absolutely screams performance and is a strong contender for the title of the best RAM . Having launched almost six years ago, DDR5 has finally hit its stride. Capacious 64GB memory modules are now available, increasing the memory kit capacity. On the other hand, retail DDR5 memory kits are aggressively pushing toward the jaw-dropping DDR5-10000 barrier, thanks to the conception of CUDIMMs.
However, just when DDR5 is flourishing, a memory shortage rains on its parade. It's such a terrible time for high-end memory kits, such as the Cras V RGB DDR5-9600 C46. However, it represents the pinnacle of DDR5 performance and deserves a place in the spotlight, even if it's unobtainable for many.

Admittedly, the previous review was of a more modest DDR5-6400 configuration . For those unfamiliar with the Cras V RGB's design philosophy, the memory modules feature a premium aluminum heat spreader with a matte finish that's available in either obsidian black or brilliant white trim. The kit we're testing today features the former.
The heat spreader flaunts an angular design with a raised central ridge that tapers toward both the top edge and sides. Klevv has exercised restraint with the Cras V RGB and kept the branding to an absolute minimum. Even with the RGB diffuser, the memory modules only measure 1.73 inches (44mm) in height. The good news is that you don't need proprietary software to customize the lighting. The Cras V RGB is compatible with Asus Aura Sync, Gigabyte RGB Fusion 2.0, MSI Mystic Light Sync, and ASRock Polychrome Sync.

Removing the heat spreader reveals eight SK hynix H5CGD8MHBDX021 (M-die) integrated circuits (ICs) residing on a single side of the 10-layer black PCB. Each M-die IC contributes 3GB to the total capacity. Power management duties fall on the 0P=CD 5YB power management IC (PMIC) from Richtek. Although not advertised as a CUDIMM on the packaging, the Cras V RGB DDR5-9600 memory kit employs CUDIMM technology, specifically the DR5CKD1GC0 clock driver (CKD) from Rambus.
When first installed onto the motherboard, the memory will run at DDR5-4800 with the usual 40-40-40-77 timings. There are two memory profiles on the memory modules, supporting Intel XMP 3.0 and AMD EXPO. The primary DDR5-9600 profile will increase the timings to 46-58-58-125 and DRAM voltage to 1.45V. Surprisingly, the secondary profile is just a notch below with data rate and timings at DDR5-9200 and 42-56-56-148, respectively. The DRAM voltage remains at 1.45V.
