Great Value!
Review Summary
The Biwin HX100 Black Opal 2×24GB DDR5 kit delivers strong performance at 6000MHz CL28, making it an excellent match for AMD systems and a solid choice for Intel builds, too. It skips RGB lighting for a clean silver or black look, comes with both XMP and EXPO profiles, and features efficient cooling with an aluminum heat spreader. Tight timings give it an edge over similarly specced kits, and there’s even headroom for overclocking to 6600MHz if you’re willing to raise the voltage. With good build quality, stable performance, and a reasonable price, it’s a practical, high-performing memory kit.

Earlier, I tested Biwin’s premium RAM solution in the form of the DW100 RGB kit. This time, I’m taking a look at the mainstream HX100 series from Biwin. The kit in the spotlight is the Black Opal 2×24GB, operating at 6000MHz CL28, making it a solid option for AMD users.
This kit comes with both Intel XMP and AMD EXPO profiles, programmed with the same parameters. The series does not feature RGB lighting but is available in black and silver color options for a bit of visual variety. The maximum available speed in this series is 7200MHz, with capacities of 2×16GB, 2×24GB, and 2×32GB.
This non-binary kit carries a price tag of £124, with an expected price of around $145.
Key Takeaways
- The Biwin HX100 48GB DDR5-6000 CL28 is a clean-looking DDR5 kit with tight timings, solid cooling, and great performance, especially for AMD builds.
- You should buy the Biwin HX100 if you want one of the best-timed kits for AMD at 6000MHz CL28 and prefer a clean, non-RGB design available in silver or black.
- You should not buy the Biwin HX100 if your build has limited RAM clearance, as its 47mm height can cause issues with some air coolers.
Here are the key specs:
| Memory Type | DDR5 CUDIMM |
| Capacity | 2x24GB |
| Tested Speed (EXPO/XMP) | 6000MT/s |
| Tested Latency (EXPO/XMP) | 28-36-36-72 |
| Tested Voltage (EXPO/XMP) | 1.40V |
| Warranty | Limited Lifetime |

What Makes It Different?
Biwin HX100 DDR5 kit operating at 6000MHz CL28 is a no-frills, full of performance kit that would be handy dandy for your AMD platform in particular. What makes this kit even more potent is its overclocking potential. You can’t go wrong with this kit.
Packing Box
The kit comes in a black color packaging box made of paperboard. We have got the silver edition. The memory modules are nicely tucked inside the transparent container.
Design
These are the salient features of the kit:
- The kit has XMP 3.0 and EXPO profiles
- The kit uses specialized cooling, reducing the temperature by 5°C
- The kit supports Overclocking
- There is a meticulously layered aluminum fin structure
- The Aluminum Alloy Heat Spreader
- Limited Lifetime Warranty
- The kit has a power management chip for stable and effective power usage
The silver color cover on this kit speaks for itself. You can see the fin design near the base of the modules. The black color border gives a subtle touch to the overall look and feel of the kit. HX100 DDR5 is printed on each module.
The kit utilizes an efficient thermal silicon pad for effective heat transfer, which is further enhanced with a fin design aluminum alloy heat spreader. You have got the aesthetics without a compromise on thermal performance.
The back side has the same layout as the front. You can see a sticker over the fin area. Removing the sticker voids the warranty. The part number of this kit is BXH54860HX1-D28FS. A serial number, speed, timing, and voltage ratings are also printed.
This kit is an unbuffered DIMM with a 288-pin layout. Each module has 1Rx8, meaning a single rank design using 8 modules. These kits are made in China. This kit has dimensions of 47×136.6×8.4mm (HxLxW).
The kit does not come equipped with ARGB LEDs, and it has no branding on the top; hence, there is nothing fancy over the top of this kit. The only thing adding some look is the cutouts.
The PCB is black, which is standard for DDR5 modules. One side is populated with the ICs and active circuitry, while the other side is blank and fitted with a thermal pad of the same thickness, ensuring the PCB sits evenly between the heat spreaders.
There are four memory chips on the left of the integrated PMIC chip and another four on the right, providing a total capacity of 24GB in a 1Rx8 configuration using a 3G x 64-bit design.
I have used AIDA64 to read some hardware data since Thaiphoon burner could not read the bus. Memory chips are from SK Hynix. The PMIC controller is from Richtek, having a part number of PMIC5100. This kit is manufactured in the 16th Week of 2025.
This kit has Intel XMP Revision 3.0 and AMD EXPO profiles programmed. Both profiles have the same parameters:
- 6000MHz 28-36-36-72 1.40V
Testing
We are using below mentioned configuration for RAM testing:
- Intel Core Ultra 7 265k [Stock, Auto]
- Lian Li GA-II Lite 360 Performance
- ASRock Z890 NOVA WiFi
- Sabrent Rocket 4 Plus 1TB PCIe 4.0 NVMe SSD [For OS]
- Intel Arc B580 [For Display]
- Fractal Design ION+ 2P 860W Platinum PSU
- Thermaltake Core P6 TG Snow Edition in an open frame layout
I used these benchmarks to test the performance of the kit:
- AIDA64 Engineer
- SiSoftware Sandra Suite
- Performance Test
- 3DMark Time Spy
- Super Pi
BIOS Run
The kit has a single XMP and EXPO profile. The programming is accurate, and the motherboard on auto picked up the programmed data.
CPU-Z
The above is a CPU-Z screenshot. Looking closely, you will notice that the software is reporting the kit to be in quad-channel configuration. The reason for that is that with DDR5 kits, we have two channels per module with each being a 32-bit wide.
Results
Let’s start taking at the results one by one.
AIDA64 Engineer
The overall result of the kit operating at 6000MHz is marginally better than the XPG kit operating at the same frequency. The difference comes from the tight timing on the Biwin kit. However, the read operations are slow on Biwin for some odd reason.
Other Benchmark Software Results
The Biwin kit has a better performance compared to the XPG kit, operating at the same speed. The advantage of the Biwin kit is its super-tight timings.
Overclocking
I managed to push the kit to 6600MHz, with still a better timing of CL30, though I had to use over 1.50V to achieve this result, with which I am not super comfortable for 24/7 operations.
Should You Buy It?
Buy It If
✅You want the best timing kit for AMD: 6000MHz is still the best pick for the AMD platform, and the advantage would come from the kits operating at tight timings. The Biwin HX100 kit operates at 6000MHz with CL28.
✅RGB is not your requirement: This kit is available in silver and black options, making it an ideal fit for the stealth builds.
Don’t Buy It If
❌RAM Clearance is an issue: This kit has a height of 47mm. This is a tall profile and could be problematic for the air coolers.
Final Words
“Where form meets function” is a fitting description for Biwin’s HX100 series DDR5 kits. These non-RGB kits deliver the same strong performance at a lower cost. I tested the Black Opal HX100 2×24GB DDR5 kit, which runs at 6000MHz with CAS28.
This kit is an ideal choice for AMD platforms, and with some patience, you can further tune the timings for even better performance. The series is available in silver and black, and each kit includes a single XMP and EXPO profile with identical parameters.
The timings are set at 28-36-36-72 at 1.40V, though aggressive overclocking will require higher voltage. It uses SK Hynix chips with a PMIC from Richtek. On Intel platforms, which typically favor higher-frequency kits, this kit still outperforms the XPG kit at the same frequency but with looser timings.
Measuring 47 × 136.6 × 8.4 mm (H × L × W), it features a solid cooling solution with a fin design, aluminum-alloy heat spreader, and thermal pad. Backed by a limited lifetime warranty, this kit earns our recommendation.
