ZSUS X99-P4

The X99-P4 motherboard appeared in 2023. It’s a typical budget Chinese board aimed at entry-level builds.

You’ll most often find it branded as ZSUS, but it’s also sold under MUCAI, MOUGOL, MACHINIST, Atermiter, Soyo, and even Huananzhi.

There’s a simplified version of this board that retains the same PCB markings — the ZSUS X99-8D4.

Specifications

The X99-P4 doesn’t stand out among other budget boards. It provides the bare essentials in terms of modern I/O. The storage subsystem offers just 3 SATA ports (only one of which is SATA 6 Gb/s) and a single M.2 slot that is switchable via jumpers; it’s configured for NVMe by default.

The VRM is clearly not this model’s strong suit. It uses a classic budget configuration of three doubled phases and is not designed for high-performance processors. The board uses MOSFETs marked PQ PN0301 (x6 high-side) and PQ PN0302 (x6 low-side).

Audio is handled by the Realtek ALC897 codec. On the downside, the usual Chinese budget-board quirks apply:

Common Limitations of Budget Chinese X99 Motherboards:

Temperature Monitoring Issues

Temperature monitoring doesn’t work properly on most budget Chinese X99 boards. Onboard sensors are non-functional and display erratic readings (such as 120°C+ in monitoring software like AIDA64) due to faulty sensor implementation. However, CPU temperature monitoring via the processor’s built-in sensors remains accurate.

Limited Fan Control

Fan control only works with 4-pin PWM CPU coolers. 3-pin case fans run at constant speeds without automatic regulation. Consider using manual fan controllers or PWM adapters as workarounds.

BIOS Limitations

The BIOS implementation is often incomplete. You’ll find numerous settings and options, but many simply don’t function as intended or have no actual effect on system behavior.

Most critically, memory timing controls are hidden in the stock BIOS. This prevents manual RAM overclocking and fine-tuning. However, you can solve this by flashing modified BIOS versions that unlock these hidden advanced memory timing options and other concealed features.

AIDA64 Freezing

Chinese boards with desktop chipsets (H81, B85, Q87, etc.) have broken motherboard temperature sensors that freeze AIDA64.

Fix: Disable the faulty sensor in AIDA64

• Enable status bar: View → Status Bar
• Right-click the status bar at the bottom → HWMon Modules → uncheck PCH / Bibxy
• If this doesn’t help – disable all sensors and enable them one by one to identify the culprit.

Revisions

Different versions of the board exist, built on various chipsets: desktop H81 and server‑grade C222 and C612. While functionality remains similar across versions, their firmware may be mutually incompatible.
It cannot be reliably determined visually which chipset a particular sample uses. However, revisions with larger chipset heatsinks are likely based on the C612 PCH.

BIOS Capabilities

The stock BIOS is based on American Megatrends code and is unremarkable. The typical constraints apply, with the main limitation being the lack of RAM timing controls. Fortunately, the X99‑P4 is compatible with firmware from certain other Chinese boards that expose at least basic timing settings.

After flashing, reset settings to defaults (Clear CMOS).
