Chapter 1. Overview

GPUMon is a GPU diagnostic and monitoring utility for NVIDIA® products.

GPUMon includes the following features:
 Monitor GPU temperature, clocks, P-state, utilization, and TGP.
 Enable/disable thermal control, NVIDIA GPU Boost™ technology, and fan control.
 Check DevID, driver, VBIOS, strap, and power.
 Set PCI Express Gen speed, link width, ASPM feature.
 DisplayPort (DP) link training, drive strength, and DP device AUX read/write.
 Log GPU-related information, including EDID, PCIe error, GC6.
Note that GPUMon replaces ThermSpy and ThermSpy is no longer supported. All references to
ThermSpy in NVIDIA product collateral should be replaced with GPUMon.

1.1 Limitations
GPUMon relies on NvApi interface, and its functionality may be limited if one (or more) of
following cases occur:
 If running on system with older drivers (depends on when particular feature was exposed
over NvAPI).
 If NvAPI call/underlying RM support is not available for given GPU.
 Incomplete VBIOS settings.

Chapter 2. The GUI

GPUMon shows slightly different user interfaces depending on the NVIDIA product. As shown
in the following figures, GPUMon is composed of two parts: Control Panel (the left-hand side)
and Display Panel (the right-hand side). Both panels contain selectable tabs to switch between
various functions.

2.1 Control Panel

The following sections describe GPUMon control Panel.

2.1.1 GPU Information

This section displays GPU name and state:

NVIDIA CONFIDENTIAL
GPUMon ReadMe DA-08558-01_v04 | 3
 The GUI

 GPU Name
• If running on a multi-GPU system, users can cycle through the GPUs by clicking on the
Next GPU button.
• On a single GPU system, the Next GPU button is grayed.
 GPU State: GPU ON/OFF/IDLE (and GC6 for Notebook).
• For Win10 systems (wddm 2.0 or above), IDLE state will be shown as ON.
 Poll Period
• Poll Period cannot be less than 20 ms.

2.1.2 GPU Core

This section displays core information of the current GPU:

 GPU TJ: The current GPU temperature in Celsius

 TempSim: GPU temperature simulation (to manually override with a fake GPU
temperature)
• This function may be unavailable if VBIOS is locked, or the system uses external
thermal sensor.
• Check the “Thermal Overrides” section in VBIOS to unlock; external VBIOS may need
[HULK_License] to do so.
 Mem Temp: Memory Temperature
 GPCCLK: The current GPU's GPC Clock
• Green bar shows current clock percentage, which indicates hardware clock divider
kick-in when system hits power/thermal threshold.
 Mem Clock: Memory clock
 GPU Util (%): Shows current GPU core utilization
 FB Util (%): FB utilization

NVIDIA CONFIDENTIAL
GPUMon ReadMe DA-08558-01_v04 | 4
 The GUI

 P-state: Shows current GPU P-state, can also indicate P-state lock (in red).
• Use Set P-state to loop between two states or set any P-state including [Virtual P-
state]
• PerfCap Reason (with monitor bar): Show current and past performance-capping
reason as in the following table.

Table 2-1. PerfCap Reason

Name Color Description
pwr Reduce workload when TGP or core power exceeds the specified
threshold.
thml Reduce workload when temperature exceeds the specified threshold.
VOp Capping NVVDD when it hits max over-voltage limit
VRel Capping NVVDD when it hits reliability limit (default or reduced lifetime)
Util Increase P-state based on core clock utilization.

 NVVDD (W): GPU NVVDD Power in watts on supported products.

 FBVDD (W): Memory Power (memory devices + GPU FBIO) in watts.
 TGP (W): Displays TGP power in watts on supported products.

2.1.3 PCIe
This sections sets/monitors PCI Express Links, Gen, and ASPM feature on both GPU and
ROOT. This functionality may not override the PCIe settings if:

 GPU chip HW capability register disables certain link width.

 Link width can only be reduced, that is, ×16→ ×8→ ×4→ ×2→ ×1. To restore Link width
back to the default value (for example, ×16), the user must reboot the system.

2.1.4 NVIDIA GPU Boost

This section exposes the NVIDIA GPU Boost settings on GeForce® products that can be
modified for qualification or end-user overclocking purposes. Note that this GPUMon menu is
not supported on Enterprise products.

 Target Temp: Input number must be within max temperature range.

 Power Steering Enable: User can enable/disable this feature (check box is checked when
enabled).
 Thermal Controller Enable: Ensure that GPU will operate within a predefined max
temperature.
 Boost Clock Enable: Increase NVCLK limit to specified ratio (predefined in VBIOS).
 D-Notifier Limit: D-Notifier status indicator; D-Notifier power states act as a secondary
power state, with the primary power state being either AC or battery.
 GPU Clock OFFSET: set GPU clock within OC limit.
 MEM Clock OFFSET: set Memory clock within OC limit.

 GPU Clock Offset: GPU clock frequency increase at every voltage on VF curve
 Memory Clock Offset: Increase to the high frequency memory clock.
 NVVDD Offset: Increase maximum voltage beyond stock limits.
 Power Target Operating: Power target (TGP), default 100 percent
 GPU Temperature Target: The NVIDIA GPU BOOST algorithm automatically raises or
lowers the clock to prevent the GPU temperature from exceeding target temperature. If
the target temperature cannot be maintained if the board is under the power cap limit, the
NVIDIA GPU Boost feature will be disabled, and the clocks will lock to base.

In this section shows fan-related data for Desktop and Enterprise. GPUMon supports both
RPM and PWM units:

 Fan: Shows Minimum fan speed, Current fan speed, and Max fan speed
 Fan Sim: Manually set fan speed.
• RPM unit may not be able to set the speed precisely, due to fan speed granularity.
 Fan Curve: Overrides the default GPU fan curve.
 Fan Stop: Enabling this feature allows the fan to stop under the condition of TJ or TGP (or
both) less than minimum threshold.
• This feature is only available to certain SKUs.
• When disabled, fan will restart with a sequence of steps to avoid overshoot.

2.2 Display Panel

Display Panel contains of four (or five) tabs: General, EDID, PCIe, and CPU. GC6 tab shows if
the GPU is a Notebook SKU. In addition to displaying the information on the Display Panel,
GPUMon also captures the information in a text log file. Refer to the Log Start section for
