V-Color Manta XFinity RGB DDR5-6400 C32 2x64GB Review: Two-Module Powerhouse

The V-Color Manta XFinity RGB DDR5-6400 C32 isn't something to sneeze at and easily competes with some of the best RAM. Many mini-ITX and microATX motherboards have only two memory slots, a limitation that has long frustrated small-form-factor (SFF) builders. However, the introduction of DDR5 technology and new 64GB modules has transformed the landscape. SFF enthusiasts can now pack 128GB into dual-DIMM motherboards, transforming compact systems into powerhouses capable of handling demanding workloads and multitasking.

V-Color’s Manta Xfinity RGB memory modules come equipped with a sleek aluminum heat spreader, available in black or, depending on the SKU, white. The 1.5mm-thick heat spreader not only improves heat dissipation but also adds a modern touch with its geometric groove design. This minimalist look emphasizes both function and style. The memory modules stand at 1.69 inches (43mm) tall, ensuring broad compatibility with most systems. However, if you use a giant CPU air cooler, it’s wise to double-check your available clearance space before you pull the trigger.

Like many enthusiast kits, the Manta Xfinity RGB modules feature a semi-transparent light bar housing 16 vibrant LEDs for stunning lighting effects. V-Color doesn’t provide proprietary software for lighting control, which simplifies installation and setup. The company lists Asus Aura Sync, MSI Mystic Light Sync, ASRock Polychrome Sync, and Biostar RGB Sync as compatible ecosystems.

Unsurprisingly, the 64GB memory modules utilize a dual-rank design, featuring integrated circuits (ICs) on both sides of the black PCB. Each module contains 16 ICs in total, each with a 4GB capacity, arranged in two groups of eight on either side. These ICs are H5CG58MHBDX051 (M-die) from SK hynix, while the 0P=BH 3YM power management IC (PMIC) points to Richtek.

When first installed, the memory modules will operate at DDR5-4800 with 40-39-39-77 timings. The kit provides only AMD EXPO support with a single available profile. This profile sets the modules to DDR5-6400 with 32-45-45-96 timings and a DRAM voltage of 1.4V.

Comparison Hardware

The Intel system features the Core Ultra 9 285K processor and the MSI MEG Z890 Unify-X motherboard with firmware version 7E20v1A60. Conversely, the AMD system utilizes the Ryzen 9 9900X processor and the MSI MPG X870E Carbon WiFi motherboard with firmware version 7E49v1A64. The Corsair iCUE Link Titan 360 RX LCD CPU liquid-cooling solution efficiently maintains optimal temperatures for both the Arrow Lake and Zen 5 processors, ensuring efficient thermal management across platforms.

The MSI GeForce RTX 4080 16GB Gaming X Trio efficiently handles demanding graphics workloads, preventing any bottlenecks during our gaming RAM benchmarks. The TeamGroup A440 Lite PCIe 4.0 SSD balances performance and capacity, delivering 2TB of ultra-fast storage with speeds up to 7,400 MB/s—perfect for Windows 11 24H2 installations, benchmarking software, and gaming applications.

The Corsair RM1000x Shift ATX 3.0 power supply delivers reliable and ample power to our test systems, directly supporting the GeForce RTX 4080 via its native 16-pin (12VHPWR) cable. The Streacom BC1 open-air test bench offers flexible, tool-free accommodation for all hardware components, streamlining assembly and component swaps.

Intel Performance

The V-Color memory kit consistently outperformed the G.Skill, thanks to its higher frequency. While the performance gap is modest, V-Color delivered measurably better results across both application and gaming workloads—though gaming performance likely isn’t the primary draw for buyers considering this kit.

AMD Performance

The AMD platform told a different story: the G.Skill DDR5-6000 memory kit overtook the V-Color kit despite its superior specifications. The limitation wasn’t the memory itself, though. Our Ryzen 9 9900X can’t handle DDR5-6400 at a 1:1 ratio for the unified memory controller clock (UCLK) and memory clock (MEMCLK). It shows the reality that not every Ryzen chip can do it.

Overclocking and Latency Tuning

Overclocking high-capacity memory modules isn’t always rewarding. Increasing the DRAM voltage by 0.05V reached DDR5-6466 while maintaining the same timings as DDR5-6400. You could always push higher voltage or accept looser timings for better speeds, but the trade-offs often aren’t worth it.

Lowest Stable Timings

SK hynix ICs have shown that there isn’t much headroom to tighten timings. Vendors typically bin these chips to their absolute limits, which isn't a bad thing since it saves you the hassle of manual tweaking. With this memory kit, we could only reduce the tRCD, tRP, and tRAS timings by 1, 1, and 4 clock cycles, respectively.

Bottom Line

The Manta XFinity RGB DDR5-6400 C32 is an impressive memory kit that offers an excellent balance between high capacity and strong performance. It delivers the performance necessary for productivity workloads and demanding applications.

Unfortunately, this launch arrives during a global memory shortage, which means availability may be extremely limited and pricing could be higher than normal.

Before the memory crisis, this kit sold for $479.99, which was already in the premium category. It's understandable given the early production costs of 64GB memory modules. With the ongoing shortage, the Manta XFinity RGB DDR5-6400 C32 has become even more expensive and increasingly difficult to find. Currently, V-Color has only the DDR5-6800 C36 variant in stock at $1,999.99, which we consider excessive. We strongly recommend waiting until the DDR5-6400 model returns to stock at more reasonable pricing before making a purchase.
