Hello,

I have MSI Meg Ace z390 motherboard. It was overclocked to 5.0 ghz both bios and windows previously (I checked this with both HWinfo and cpuz) but after I upgraded the bios it now gives frequency of 4.7ghz in windows. Noticed this a little later on when wanted to check temperatures with HWinfo.

I used the MSI guide as a reference to the overclocking: https://www.msi.com/blog/intel-9th-cpu-overclocking-5ghz-with-z390-motherboards

I don't know what has changed that I only get 4.7ghz in windows?? Just now I loaded the latest bios in and still the same. Tried looking around internet but found no help. I have loaded default setting in bios and it shows that base frequency is 3.6ghz. When I overclock again it shows 5.0ghz in bios but only 4.7 in windows??

Please if anyone has any ideas I'm all ears!!

Best regards

Mika

Can you show me full screenshots of HWinfo64 "Sensors" with all sensors expanded (click on the little <--> arrows on the bottom)? Preferably let it run a bit while in idle, so we get some "minimum" baselines for the values, and then run a non-AVX full load like Geekbench. Make the first screenshot when it gets to the end of that. Then you can run a AVX full load like Prime95 torture test for example and make another screenshot.

Note that when you overclock the CPU according to that blog, you're basically saying goodbye to all energy saving mechanisms, as well as substantially increasing the power consumption under load. So this is not very efficient anymore, to say the least. It depends on your CPU if it's even worth it, with most 9th gen CPUs it already wasn't really worth it, if you give any value to power consumption and heat production. The 8th gen was probably the last gen where CPU OC was actually worthwhile.

If you have a 9900K for example (something you should mention when talking CPU OC is your CPU model), the heat output with OC will be quite something. Only very good air coolers can handle that, or maybe you have an AiO. Otherwise you might run into thermal throttling.

Hopefully the screenshots will give a lot of clues.
