The Z890 Valkyrie has a robust 20+1+1 VRM design that handles high component loads well. Even though it’s not the best option on the market, it’s more than enough, as new Intel processors are less demanding than the last generation and the new motherboards are improved. BIOSTAR also points out an 8-layer PCB, which is above average but also not the top option.
We couldn’t hear any coil whine or other noises from the motherboard under high load. All voltages were perfectly stable, but the CPU was overclocking worse than on competitive brands.
The motherboard supports all desktop Core Ultra processors and DDR5 RAM up to 9066MT/s+. Anything above 8600MT/s will use the clock driver, so in other words, it will be CUDIMM. However, the Z890 Valkyrie had difficulty working with our CUDIMM memory kits. It could work up to 8533MT/s with the Kingston FURY Renegade 48GB 8400MT/s and 8800MT/s kits. It was the limit, while both memory kits were tested on other brand motherboards at 9333MT/s+. We also had problems running Gear 2 mode at more than 8000MT/s, while other brands handle 9000MT/s+. Since our memory kits are market standard and all CUDIMM use the same Hynix IC, the short conclusion is that the Z890 Valkyrie is far from optimal RAM support.
BIOSTAR also suggests that the Z890 Valkyrie uses premium audio components but still uses the old Realtek ALC1220 codec. The overall audio design is pretty good and isn’t much different from what we can see on higher-series competitive motherboards. Brands like Gigabyte also use ALC1220. Audio is not getting old as fast as other features, but we still wish to see something from the latest series.

The Valkyrie gives us six M.2 sockets, which are as many as the top competitive models with the Z890 chipset. One socket supports PCIe 5.0 SSDs, while others are in the PCIe 4.0 standard. The performance is about as high as expected.
The layout is pretty good, and there are no compatibility issues. The Valkyrie also supports EZ-release for the graphics card, a huge advantage for all who replace graphics cards more often or use the motherboard for tests. The mechanism works without issues. M.2 sockets still use standard screws, but most users don’t replace SSDs more often.
The new Intel series doesn’t have native USB4 controllers compared to new AMD motherboards. However, all Z890 motherboards have Thunderbolt 4, which supports USB4 devices. Thunderbolt 4 is a better option for some users, providing more functionality, but most users won’t see a difference.
The Valkyrie has a BIOS flashback button on the back I/O and a dedicated USB port, so we can update the BIOS even without the CPU.
BIOSTAR decided to install two NICs on the Z890 Valkyrie. One is already standard 2.5Gbps, and the second is a 5Gbps port. Both chips come from Realtek, which is good news for those who want to use less popular or server operating systems, as most of them have built-in drivers.
The disadvantage is that the Valkyrie, like other BIOSTAR motherboards, doesn’t have a WiFi and Bluetooth controller. The specifications suggest WiFi 7 and Bluetooth 5.2 support, but we have to buy the card and install it in the M.2 E-type socket designed for it.

The list of Key Features is also available on BIOSTAR’s website.
BIOSTAR lists many features, but most have been a solid standard for years or are standard options for the new chipset offered by every other brand. Everything seems correct, but we could expect some more from the top motherboard model.
Retail Packaging and Accessories
The motherboard arrived in a retail package. The package design and contents are the same as those in stores. The box is typical for an ATX motherboard but large enough to protect everything well.
Inside the box, we will find four SATA cables, a quick guide, smart front panel connectors, and Valkyrie stickers. The motherboard doesn’t have WiFi antennas, even though headers are pre-installed on the I/O back panel. This means that if we wish to use a wireless connection, we will need not only a WiFi card but also a set of antennas and probably compatible headers, as they are not guaranteed to fit.
A Closer Look at the BIOSTAR Z890 Valkyrie
The Z890 Valkyrie has a unique design and doesn’t share the PCB with any other model. The layout seems just right, and everything is easily accessible. We shouldn’t have a problem with large CPU coolers or other devices. The motherboard is standard ATX size, so it should fit every popular ATX case.
Large heatsinks cover the front, so the VRM, chipset, and M.2 SSDs should be well-cooled. On the back, an aluminum backplate cools the VRM area via thick thermal pads.
The motherboard has six fan headers, which can be controlled in the BIOS. The headers’ rating is not provided, so we should assume they have a standard wattage of around 12W per connector. They’re enough to connect a large liquid cooling setup with multiple fans.
The Valkyrie doesn’t use additional fans for a chipset or VRMs, so it’s silent during work, and we don’t have to worry about moving parts.
The Z890 chipset has a single-die design and doesn’t generate much heat, so a small heatsink can efficiently cool it. The Valkyrie’s chipset heatsink is connected to the M.2 heatsink with a thermal pad, and nothing is overheating, which confirms it doesn’t require any exceptional cooling for complete stability.
Below are additional close-ups of the motherboard’s ICs. There are no surprises, as similar components can be seen on competitive motherboards. Audio and connectivity controllers are also popular on motherboards with AMD chipsets.
UEFI BIOS and Software
BIOS/UEFI
The Valkyrie BIOS has most of the options that competitive Z890 motherboards have. There is nothing we couldn’t see before, but there is everything that most gamers and enthusiasts need. The RAM support is another thing, as we had difficulty making most of our higher-frequency memory kits work at XMP profiles. The Gear 2 mode also works much lower than on recently reviewed ASRock and Gigabyte motherboards. Other devices seem to work fine.

BIOSTAR Software
BIOSTAR adds its software, which includes RGB adjustment, fan control, overclocking and diagnostic options, memory settings details, and software/firmware updates. Two applications provide all these features.
The RGB illumination and software management worked only with devices connected via ARGB headers. We couldn’t make it work with any popular RAM brands, including G.Skill and Kingston.
Fan control works without issues and can be easily managed by the software.

In AIDA64 synthetic tests, we see lower performance than on previously reviewed Z890 motherboards, including ASRock and Gigabyte motherboards that are not listed in our comparison.
For comparison purposes, all the results were made on the 6400MT/s memory kit, so we can count on much better bandwidth if we use high-frequency CUDIMM. However, the Valkyrie doesn’t work above 8533MT/s manually, and we couldn’t make it run at XMP profiles from Kingston 8400MT/s and 8800MT/s CUDIMM. Both Kingston memory kits can reach 9200MT/s+ on all previously tested Z890 motherboards.

The PCMark 10 Applications benchmark results are also close between all Z890 motherboards.
Gaming Performance
Gaming benchmarks show that the Valkyrie is slightly slower than other Z890 models. The difference isn’t significant, so I assume it will be corrected with the upcoming BIOS updates.



We have published one more motherboard review with the Z890 chipset, while Intel has yet to deliver the promised Arrow Lake-S improvements. As long as motherboards are stable and perform similarly, we wish to see performance improvements.
Storage Performance
M.2 SSD

The M.2 performance has been tested using the Crucial T705 2TB NVMe PCIe 5.0 x4 SSD. The maximum bandwidth is around 12.45GB/s, which is expected on Intel-based motherboards. On the other hand, low queue random operations are up to 20% faster than we can see on motherboards with AMD chipsets, passing 95MB/s in the random read test. The M.2 performance is as high as expected.
USB

Since the Z890 chipset doesn’t have a native USB4 controller, we use Thunderbolt 4 with USB4 tunneling to perform USB tests. Our USB SSD performs well, and longer tasks have no problems.
Network Performance
LAN

The Valkyrie has 2.5Gbps and 5Gbps Realtek LAN ports, so we focus on the higher-speed option. Since reaching or passing the maximum throughput is impossible, around 4800Mbps is as high as we expected. We also had no problems with the connection stability during longer work.
WiFi
The Z890 Valkyrie lacks a WiFi module, so we skipped this test.
Power Consumption

Above, you can see our results for the whole test rig. It’s a typical high-end PC. The Valkyrie uses about as much power during work as most other Z890 motherboards. The power delivery seems fine.
Overclocking with the BIOSTAR Z890 Valkyrie
Intel Core Ultra processors don’t overclock as high as the last Intel generation. However, on ASRock and Gigabyte motherboards, we could reach a frequency of about 100-200MHz higher than on BIOSTAR Valkyrie. The maximum P-core frequency was 5.5GHz, while the maximum E-core frequency was 4.8GHz. Raising the voltage didn’t help to stabilize higher clocks. It’s still not a bad result, but we expected some more.

I already mentioned that our maximum RAM frequency was 8533MT/s Gear 4. It performs worse than 7600MT/s Gear 2 at the XMP profile. 8000MT/s or higher couldn’t work at Gear 2, which is disappointing. We could even reach 9200MT/s Gear 2 on the ASRock OCF motherboard, while 8800MT/s runs without issues on all of the ASRock and Gigabyte motherboards we tested. This considerable difference makes CUDIMM pointless on the BIOSTAR Valkyrie.

The BIOSTAR Valkyrie performs well, but it’s hard to call it an overclocker’s dream. It lacks high RAM frequency support and offers a limited overclocking potential.
Conclusion
The BIOSTAR Z890 Valkyrie is a stable motherboard with new features and the latest Intel processor support. Less demanding users may see it as a good motherboard, offering everything most users need. However, as a flagship BIOSTAR model, it lacks too much to recommend it to overclockers and computer enthusiasts. We had problems with RAM and RGB illumination support. The performance in some tests could also be better.
The Valkyrie doesn’t offer anything above any competitive brand. We could even say that mid-shelf models of other brands offer as much as the Valkyrie. The lack of a WiFi controller certainly doesn’t help, as it’s a standard feature in all competitive motherboards. Audio is also not advantageous as other brands moved to newer audio codecs when BIOSTAR stuck with ALC1220.
We couldn’t find the Z890 Valkyrie in any larger online store. The Z790 Valkyrie costs $400, so the new model is expected to cost more when a similarly equipped motherboard can be found for $300. However, we can’t judge the price until we see it in stores.
BIOSTAR Z890 Valkyrie is not a bad motherboard, but it offers a little above the average, which makes it hard to recommend as a flagship model designed for the most demanding users.
