ASRock X870E Taichi OCF Review: Overclocking Features Meet AM5 Reality

ASRock X870E Taichi OCF blends overclocking-focused hardware with mainstream AM5 features, raising questions about its real purpose.

While we were still working on the ASRock X870E Taichi OCF motherboard, AMD sent us a sample of the Ryzen 79850X3D. The OCF acronym stands for Overclocking Formula, which means this board is a high-end choice for people who want to overclock their computers.

At first, I had a lot of questions about the board, so I put it aside for a bit to focus on the CPU review. Later, AMD supplied this motherboard along with the Ryzen 9850X3D. This brought the spotlight back to the X870E Taichi OCF and made it easier to compare it to the ordinary X870E Taichi.

Differences in Design Between Taichi and Taichi OCF

The standard X870E Taichi is an EATX motherboard with four DDR5 RAM slots. There is an M.2 slot with its own heatsink between the memory slots and the main power connector. In comparison, the X870E Taichi OCF uses an ATX form factor and supports only 2 DDR5 memory slots. ASRock removes the extra M.2 slot and installs a row of micro buttons in its place. These buttons are only for overclocking.

Both boards have a lot of the same hardware when disassembled. The VRM arrangement looks the same on both the ordinary Taichi and the Taichi OCF. In terms of connectivity, the differences become evident. The standard Taichi has six SATA connectors arranged at right angles to each other, but the OCF has only two. The location of the connectors along the bottom border is also very different on the two boards.

Focus on Overclocking and Rear I/O

The standard X870E Taichi has a typical arrangement on the back I/O panel, with several USB Type-A connectors and two USB Type-C ports that enable USB4. Taichi OCF has a physical flick switch that lets you switch between BIOS A and BIOS B, which replaces part of this arrangement. It also has a PS2 port, which overclockers like since it stays reliable even when USB input devices fail under duress.

We may compare this method to the MSI Z890 Unify-X, an Intel Arrow Lake motherboard designed for overclocking. The board has many USB ports, two DDR5 slots, and dual PS/2 ports. It also has substantial protection and a big VRM. In light of this, ASRock's design decisions for the X870E Taichi OCF align with what overclockers want these days.

Things to Think About and Worry About on the Platform

X870E Taichi OCF supports socket AM5 and is compatible with AMD's Zen4 and Zen5 processors. That makes it useful for people who like to do things themselves, especially since AMD's 3D V-Cache chips are popular for gaming. But as the Ryzen 79850X3D test shows, these CPUs don't overclock well. This makes it hard to use typical overclocking methods on motherboards and processors that don't get much out of them.

Another concern comes from ASRock's poor record of reports of broken Ryzen CPUs. These reports come up a lot, whether they are true or not. When contacted directly, ASRock said they were aware of the reports, but didn't say anything else. That makes it hard to know what to expect from X870 motherboards in general, especially those made for enthusiasts who might want to manually change the voltage and clocks.

ASRock's Claims About Overclocking

ASRock talks a lot about memory overclocking, including AMD EXPO and DDR5 speeds of up to 10400. They have tables that show voltages, timings, and frequencies. Memory voltage is between 1.4V and 1.45V at DDR58000. At higher speeds, the numbers reach 1.55V. You might wonder whether it makes sense to use such a high voltage on expensive memory.

ASRock also talks about some CPUs, including the Ryzen 58500G and Ryzen 38300G, that work with these memory targets. Those CPUs aren't useful for modern enthusiast builds. Next, we'll talk about the VRM. The VRM design is the same as the standard X870E Taichi; there are no problems. The ability to handle fast M.2 SSDs is a big deal, but this is true for all flagship boards.

The OC button guidance is the most important part. The purpose of these hardware buttons is to increase the base clock speed. ASRock says that exceeding 104 MHz might require raising the CPU core voltage. Given the existing concerns about how voltage works on Ryzen systems, manually boosting it doesn't make people feel good about it.

How the BIOS Works and how the Buttons Work

We looked at the ASRock overclocking tools with the system running BIOS version 2.01 and GSkill memory set to EXPO DDR58000. You may alter how much the base clock varies and save profiles in the BIOS. But tapping the buttons did not change anything.

In Windows, CPU-Z always showed the base clock at 100 MHz, no matter which button was pressed. You could only change the base clock with ASRock's Windows program. This means that the physical buttons didn't work during testing.

Problems are due to the BIOS chips on the board, which came with BIOS 0.2, which appears to be a beta version. There are just two BIOS versions for the OCF on ASRock's website. BIOS2.01, which had processor support notes when it was first installed, has since disappeared. Even if it works fine, the lack of clarity about BIOS support makes people less sure about the board's main feature.

Results of Performance Testing

We tried a small change to the base clock: from 100 MHz to 103 MHz. Geekbench6 ran on its own settings, and with the higher base clock, it produced somewhat lower results, indicating the system was unstable rather than performing better. So, tweaking the base clock was no longer done.

The test setup included a Phanteks Glacier 360 CPU cooler, an MSI Ventus 3X RTX 4090 graphics card, a G.Skill Trident Z5 DDR5-58000 RAM, and a Seasonic Focus 1000 PSU.

Taichi OCF and the ordinary X870E Taichi performed almost the same in Geekbench 6 multicore and single-core testing. The OCF showed slightly lower results than predicted in AIDA64 memory bandwidth tests. In Far Cry 6, the OCF was ahead by a few frames at 1080p, but at 1440p the results were almost the same.

Design, Features, and Ease of Use

X870E Taichi OCF works with Ryzen 7000, 8000, and 9000 processors that fit in the AM5 socket. It has two DDR5 slots that can hold up to 128GB of memory and support DDR510400 when overclocked. Expansion features a PCIe 4x4 slot and two PCIe 5x16 slots that can be configured as x16 or x8/x8. There are two Gen5 M.2 slots, three Gen4 slots, one Gen3 slot, and two SATA connectors for storage.

There are 22+2+1 controllers and 110A smart power stages in the VRM. Two USB4 Type-C ports can transfer data at 40 Gbps, many USB3.2 Gen2 connections that can transfer data at 10 Gbps, front-panel headers that can give up to 36W of power, 5Gb Realtek Ethernet, Wi-Fi7, and Bluetooth5.4. There are three ARGB headers, one RGB header, seven PWM fan headers, and an extra PCIe power connector.

There are lights on the back I/O shroud and around the bottom of the board. Even though it has an overclocking label, the board supports full RGB, making it like a regular Taichi with more controls.

On an open test bench, the small buttons for power, reset, debug display, and BIOS switching are helpful. Their utility goes down once they're in a case, but they're still handy for hands-on testing. It's easy to see that the power and reset buttons don't light up, unlike the other buttons.

Final Thoughts

The hardware feels strong, the design is unique, the micro buttons and debug display are helpful, and the back I/O BIOS switch lets you recover from problems. There are still questions about the safety of Ryzen CPUs, the hardware overclocking buttons didn't work during testing, and it's not certain when they will be available, even if the price is projected to be under $500.

We don't want to raise the base frequency or the CPU voltage. Curve Optimizer is still the best way to tweak Ryzen processors. The board gets a 3 out of 10 for its overclocking philosophy. If you think of it as a more feature-rich version of the ordinary Taichi and don't use the manual overclocking buttons, it becomes closer to 8/10. It can still be a good high-end AM5 motherboard if you can locate it at a good price.
