Sensor readings disappear (Asus Maximus IV Extreme-Z with AI Suite II)


Recommended Posts

When running AIDA64 and AISUITE II at the same time, after some time AISUITE II displays warning message that iGPU voltage is zero. After this message appears sensor readings disappear from AIDA64. Sometimes CPU temp reading reads196C with memory voltage zero.

AIDA64's SMBus access is set to ACPI (ASUS).

It is definitely a conflict between Asus AI Suite II and AIDA64. We've already contacted Asus a while ago, and asked them to implement the now industry standard mutexes that many sysinfo and diagnostics software use (e.g. AIDA64, HWiNFO32/64, CPU-Z, HWMonitor, SpeedFan, SIV, etc) to make sure their low-level code doesn't collide with each other when you use multiple of such software in the same time. But Asus don't seem to care about that at all. So in case you observe any collisions between such 3rd party software and AI Suite II, then I'm afraid it can only be solved if you put a bit of pressure on Asus to improve their software.

Hi, I had a similar problem when running the 2 together, AI Suite reported 2nd VTTCPU voltage as 0V every now and then and PCH temps ranging from -50k to 800c.... Weird, And the CPU temp would lock to 40C after a while - guessing it got stuck when both of you tried to read it :(

I'll try to add my voice to the choir to make Asus use mutexes.

BTW, why is AI Suite able to see so many more sensors than Aida64? THis is on RE4.

Rampage IV Extreme uses a peculiar bank switching mechanism on its EC (Embedded Controller) chip. Due to the collision between AI Suite 2 and 3rd party applications, potentially it would be dangerous to switch EC banks from AIDA64. Hence AIDA64 only reads the sensor values available in the default EC bank (which is bank #0).
