Microstar International Co | Ltd Firmware 1010 Hot

Previous "100x" updates have focused on:

Version 1010 builds on these foundations. It is widely considered a "hot" update because it addresses recent performance regressions or unlocks new overclocking headroom.

“Version 1010 enhances system stability and security. Temperature reporting aligns with AMD/Intel reference guidelines. Users may observe higher readouts while actual die temperatures remain within spec.”

No, if temperatures are within safe ranges. The 1010 update includes critical security/voltage fixes. Higher reported temp is often offset + better performance.

Yes, if you see:

From user reports and MSI release notes (circa 2023–2024), the “hot” aspect stems from two opposite issues:

| Aspect | Details | |--------|---------| | Hot as in “urgent” | The update was a recommended hotfix for a critical bug, such as USB dropouts, LAN disconnection, or boot failures. | | Hot as in “temperature” | Some users reported higher CPU idle/load temperatures after updating to BIOS 1010 due to more aggressive boosting or altered fan curves. Others saw lower temperatures thanks to better voltage control. |

Example from MSI forums (summarized):

“After updating to BIOS 7C56v1A (version 1.0.1.0) on my MSI B550 Tomahawk, my Ryzen 5800X runs 5–8°C hotter at idle. Disabling Core Performance Boost in BIOS fixes it.” microstar international co ltd firmware 1010 hot

Conversely, on some MSI X670E boards, BIOS 1010 reduced high VRM temperatures by adjusting the SoC voltage.

Multiple factors contribute to perceived or actual temperature increase:

| Factor | Explanation | |--------|-------------| | Temperature reporting offset | MSI changed the Tctrl (temperature control) sensor from Tdie to Tctl/Tdie average. Results in +5–10°C readout vs older BIOS. | | Aggressive boosting | 1010 lifts power limits (PPT, TDC, EDC) for X/XT CPUs. Ryzen 9 7950X may boost to 95°C by design (thermal target, not overheating). | | SoC voltage fix | Earlier BIOS allowed >1.4V SoC → high idle temps. 1010 caps at 1.3V, but some boards respond with slightly higher Vcore at low loads. | | Fan curve reset | BIOS update resets custom curves to “Standard” or “Silent” → fans run slower at same temp. | | DDR5 training | Memory context restore disabled by default in 1010 → longer/training cycles heat IMC. |

Fix:

The most significant change in this revision is the update to the Intel CPU Microcode. This is a crucial update for users running 13th and 14th Generation Intel Core processors.
