Strange FSB/CPU MHz values on MSI 870A-G54


Recommended Posts

I've been using Everest for a long time to display various values on my Logitech G19.

Without having changed anything on my PC, something went wrong after a reboot. Everest always read the correct values for my Phenom II X6 1055T (2.8 GHz @ 200 MHz FSB or IDLE 800 MHz @ 200 MHz FSB), but after a reboot the values went crazy and Everest showed 3156 MHz @ 193 MHz FSB and IDLE 2184 MHz @ 188 MHz FSB.

Then i upgraded Everest to the new AIDA64, but it also reads the wrong values!! The FSB speed switches from 70 - 213 MHz, but never shows the correct value of 200 MHz, also the IDLE frequency is wrong it always shows 11 x 198.40 MHz = 2184 MHz in the overclocking section and on my G19.

My PC isn't overclocked, the CPU and the FSB run @ standard frequency!! Every other program (eg. Open Hardware Monitor or CPU-Z) reads the correct values!

What can i do that AIDA64 reads again the correct values?? A re-installation of AIDA64 haven't helped so far!!

My system: Phenom II X6 1055T on a MSI 870A-G54 mainboard, OS: Win 7 64 bit.

Sorry for my bad english ;-) !!!

We've completely revamped the CPU core clock, CPU multiplier, and HTT clock measurement on AMD K10 family processors (e.g. Phenom, Phenom II, Athlon II). Make sure to upgrade to the latest beta version of AIDA64 Extreme Edition available at:


After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

Let me know how it works.

The new Beta improved the reading of the FSB frequency, now it's shown correct as 200 MHz all the time.

But the multiplier is still not correct read, at IDLE it shows all the time 11x200 MHz = 2200 MHz, CPU-Z shows again the correct value of 4x200 MHz = 800 Mhz.

Waiting for the next Beta :)
