ASRock Timing Configurator

ASRock Timing Configurator is a free Windows utility from ASRock that shows the full set of DRAM timings your memory is running at, and on some ASRock boards lets you adjust them, without rebooting into the UEFI setup. People searching for “asrock timing configurator” usually want to check what XMP/EXPO and the board’s auto-training actually applied, or to fine-tune memory on an ASRock motherboard.

For miners the interest is mostly CPU mining. Memory-hard algorithms such as RandomX, used by Monero, depend heavily on how the memory is configured, so seeing the real primary, secondary and tertiary timings is the first step before tuning. The tool is made for ASRock boards only, and the build you need depends on your board.

ASRock Timing Configurator at a glance

What it does

• Shows the memory frequency, command rate and primary timings (tCL, tRCD, tRP, tRAS).
• Shows secondary and tertiary timings such as tRFC, tRRD, tFAW, tWR and tREFI, which most monitoring tools hide.
• Displays values per channel, so you can spot a mismatch between channels after auto-training.
• On supported boards, offers a set of DRAM settings for tweaking from Windows, as ASRock describes it.
• Gives a quick before-and-after record when you change memory settings in the UEFI setup.

How miners use it

Check what XMP or EXPO really applied

1. Install the build listed for your board and run it as Administrator.
2. Compare the frequency and primary timings with the values on your memory kit’s label.
3. Check tRFC and tREFI: the board’s auto values for these are often loose and can be tightened in the UEFI setup.
4. Take a screenshot as your baseline before changing anything.

Tune memory for CPU mining

1. Record your baseline hashrate with your CPU miner, for example XMRig, over at least 10 minutes.
2. Change one group of timings at a time in the UEFI DRAM settings, then boot and confirm the new values in Timing Configurator.
3. Run a memory stress test before mining; unstable memory can produce invalid shares or silent errors.
4. Re-measure the hashrate and keep only changes that are both faster and stable.

Audit identical rigs

1. On each machine with the same board and memory kit, open Timing Configurator and compare the values.
2. If one machine is slower, different auto-trained timings are a common cause; copy the working UEFI profile across.

Install and first run

Use the build from your board’s page. ASRock does not have a standalone product page. The utility appears in the Download section (Utilities) of individual motherboard pages, and ASRock support advises using the version listed for your board, because others may not work or not work correctly.

Windows 11 and driver blocking. The tool uses an ASRock kernel driver to read memory settings. Older builds (for example 4.0.9) use a driver that Windows 11 blocks, so the program fails to start. Users on ASRock’s forum report that 4.1.0 from recent board pages ships an updated driver that works. Do not turn off Windows’ vulnerable driver protection or Core Isolation to run an old build; look for a newer build instead.

Other brands. ASRock only ships the tool for its own boards. It may start or show wrong values on other motherboards; for MSI, ASUS or Gigabyte systems use a tool designed for that platform.

Mining OS users. Linux-based mining systems cannot run it. Check timings on a Windows install or in the UEFI setup.

Limitations

• ASRock boards only, and only boards whose download page lists it. AMD-platform support depends on the board and build.
• Changes made from Windows may not survive a reboot; permanent settings belong in the UEFI setup.
• Tight timings and higher memory voltage can cause instability, data corruption and, in rare cases, hardware damage. Overclocking may void your warranty.
• Closed source, no public changelog, and version numbers vary between board pages.
• Better memory timings help memory-hard CPU algorithms, but they do little for GPU mining.

ASRock Timing Configurator vs alternatives

On AMD Ryzen systems, the free ZenTimings utility is the usual way to read timings on any brand of board. Thaiphoon Burner reads the SPD chip on the memory module itself, which shows what the module is rated for rather than what the board applied. For CPU and power behaviour rather than memory, Quick CPU shows core parking, frequency and power settings in Windows. If you want to update the firmware of an older ASRock board instead, see UEFI BIOS Updater.

FAQ

What is the latest ASRock Timing Configurator version?

Version 4.1.0 (September 2024) is listed on ASRock’s Z590 OC Formula download page; newer 4.1.x builds have been reported for recent boards. Always take the build listed for your own board.

Does ASRock Timing Configurator work on Windows 11?

Recent 4.1.x builds do. Older 4.0.x builds use a driver that Windows 11 blocks, so update rather than disabling security features.

Does it work on non-ASRock motherboards?

ASRock does not support that. Use a tool made for your platform, such as ZenTimings on Ryzen systems.

Is there a portable version?

ASRock distributes it as an installer from motherboard pages; unofficial portable repacks are not from ASRock and are best avoided.

Is ASRock Timing Configurator safe?

Reading timings is safe. Changing them can make the system unstable, so change little at a time and test before mining.

Will tighter timings make mining profitable?

They can raise hashrate on memory-hard CPU algorithms, but profitability depends on electricity cost, hardware and coin prices.
