Biwin HX100 Silver 48GB DDR5 6000MHz CL28 Kit Review

My last take on DDR5 category was G.Skill Trident Z NEO RGB kit with a capacity of 32GB operating at 6400MHz CL30. This kit is optimized for AMD platform. This time I am taking a look at a kit from Biwin, which is HX100 48GB operating at 6000MHz CL28. The operating voltage is 1.40V.

This kit is available in silver and black colors, and it is non-RGB. Biwin has focused on the cooling aspect in particular, hence we have a tall profile on this kit. This kit retails at around £124 and USD145. It comes witha limited lifetime warranty.

Specifications

Packing Box

The kit comes in a standard packing box made of paperboard material. Biwin has focused on Heatsink UDIMM. I have got a silver kit.

Box Contents

The box comes with only the kit of RAM, which is standard these days anyway.

Closer Look

The HX100 series is a mainstream category from Biwin, unlike the DW100, which carries premium RAM kits. The following speed kits are available in HX100:

• 6000 MT/s
• 6400 MT/s
• 6800 MT/s
• 7200 MT/s

Tested latencies (CL) start from an impressive 28 and go up to 36, depending on the transfer speed rating. The following capacities are available:

• 2x16GB
• 2x32GB
• 2x24GB

These kits come equipped with AMD EXPO and Intel XMP unless stated otherwise.

Each module is 16GB. The heatsink is in silver color and features fin design that you can see towards the base. The black border adds a nice addition to the overall look and feel of the kit.

The kit utilizes an efficient thermal silicon pad for effective heat transfer, which is like a cherry on top of an aluminum alloy heat sink design.

Looking at the backside of the same module, we can see that the overall layout is similar to the front. The main difference is a label pasted here. Removing this sticker would void the warranty. Wondering when manufacturers will move on from the warranty void mindset!

The part number of this kit is BXH54860HX1-D28FS. In addition, the timing, speed, voltage, and serial number of the kit are also printed on the sticker. This kit is an unbuffered DIMM with a 288-pin layout. Each module has 1Rx8, meaning a single rank design using 8 modules.

The top of these kits has a minimalistic design, which is understandable as these are non-RGB kits; hence, there is no thick diffuser running over the top, and Biwin has wisely not put any branding on the top for that clean look.

One side of the kit has a pad that runs the entire length of the module, confirming that it is a single-sided module (1R). The PCB seems to have 10 10-layer design. The other side of the PCB is populated with DRAM chips and circuitry.

The PCB has a total of 8x chips. The PMIC chip is in the center. This gives a 24GB capacity in 1Rx8 using a 3Gx64-bit design. This kit uses SK Hynix Die. The PMIC controller is from Richtek, having a part number of PMIC5100. This kit is manufactured in the 16th Week of 2025. The kit has a single XMP and EXPO profile each programmed using the same parameters, 6000MHz 28-36-36-72 1.40V.

Testing

I have used the configuration below for testing:

• AMD Ryzen 9 7950X
• ARCTIC Freezer 27 eSport Duo [Performance comparable to the NH-D15]
• GIGABYTE X670E AORUS MASTER
• XPG NVME SSD 1TB [For OS]
• Sabrent Rocket 4 Plus 2TB PCIe 4.0 NVMe SSD
• ASRock Phantom Gaming RX 7600 OC 8G [For Display]
• Be quiet! Straight Power 11 850W Platinum
• Praxis Wetbench

Other kits are:

• Kingston FURY RENEGADE DDR5 32GB 6400MHz CAS32
• G.Skill Trident Z NEO RGB DDR5 32GB 6400MHz CAS30
• XPG Lancer RGB DDR5 32GB 6000MHz CAS40

I have used the software below for testing:

• AIDA64 Engineer
• SiSoftware Sandra Suite
• Performance Test
• 3DMark Time Spy
• Super Pi

BIOS Run

I did not experience any issue in the BIOS setting up this kit. The EXPO loaded the programmed parameters fine, and the system booted up on the next restart as it should. The SPD information confirms the programmed parameters. The JEDEC frequency (Default on the kit) is 5600MT/s using 45-45-45-90 timings at 1.10V.

CPU-Z Readout

The above is a CPU-Z screenshot. It confirms that the kit is operating at 6000MHz with correct timings. The kit is in quad-channel. The reason for that is that DDR5 kits have two channels (32-bit wide) per module.

Results

Let’s take a look at the result:

We can see that both kits operate in a close range in AIDA64 Memory Read, Write, and Copy benchmarks. This is mainly due to the same speed of 6000MHz. The result would be in the latency department.

The Biwin kit has a tight timing with CL 28 compared to CL 40 on the XPG kit. This has resulted in a better latency on the Biwin kit.

Both kits have similar scores in SiSoft Sandra Overall Memory benchmark.

The Biwin kit has a better timing, which is coming from its low latency or tight timings compared to the XPG kit.

We have a comparable performance from both kits.

We are seeing a tight competition again between both kits with a marginal difference.

Conclusion

I have tested the Biwin HX100 Silver 48GB kit. This kit comprises 24GB modules and comes in black and silver colors. The rated frequency on this kit is 6000MHz with a tight timing of CL28, making this kit an ideal companion for your AMD platform.

This kit supports AMD EXPO and Intel XMP profiles with the same parameters. This kit conforms to JEDEC 5600MHz default speed using 1.10V default voltage, which is even better than the G.Skill and Kingston kits since those have JEDEC speeds of 4800MHz. One reason for this is that both kits are from the start of DDR5. JEDEC revised the parameters starting from Intel’s 13th and 14th generations.

The dimension of the Biwin kit is 136.60x47x8.40mm (LxHxW). The 47mm height makes this kit a high-profile or taller one. You may want to check on the clearance with respect to the air cooler. This kit does not pack RGB lighting.

This kit has a limited lifetime warranty from the manufacturer, and it is retailing at £124/USD145, providing a good value to the user, given its tight timing for the same speed in this class and more capacity. In our testing, this kit has performed marginally well against the XPG Lancer RGB DDR5 32GB @ 6000MHz CL40. It comes recommended by us.

Pros:

• 6000MHz High speed
• CL28 tight timing
• Stylish Aluminum Heat Spreader
• 1x AMD EXPO Profile
• 1x Intel XMP Profile
• Competitive Performance
• Limited Life Time Warranty
• Price

Cons:

• Availability
