I replaced my FOXCON H61 MXE-V with used ASUS P8Z77-V-LE PLUS motherboard
Everything was great until i encountered severe stutters,high cpu/gpu temperatures,shut downs,black screen,ram problems etc.... you can read more here :http://www.tomshardware.co.uk/answers/id-3757957/problems-mobo-pcie-ssd.html
Now i got back my H61 mobo and installed fresh Windows 10 but something its not right,in CPUZ (Task menaget too) i can only see 1596MHz and sometimes goes up to 3200 or 3395MHz max cpu speed.The i5 3470 has 3.2 GHz base and turbo up to 3.6GHz but its never reaching 3.6GHz like it was before.

I can see cpu spikes all the time and most of the time core speed sits at 1596MHz but if i do something core speed goes wild like from 1.5GHz-3.2GHz-1.7GHz-2.5GHz it wasnot like before.
Also in bios i can see temperatures going up to 45C,before it was like 30-35 max.
Have i somehow damaged my cpu?

It seems unlikely to me that the motherboard caused high CPU and GPU temps. Usually motherboard issues are in the 'work/don't work' or 'unstable' category.

I can't read that other thread. When you switch to the Asus, did you do a clean install of Windows?

In the now, with your old board, you write about things you notice but don't write about actual performance. Is it performing well? As far as current temps, you've changed the thermal paste so that could account for the difference in old vs new temps. If you used too much thermal paste or used too little thermal paste that could explain it.

Have you replaced the thermal compound between your CPU and heatsink? Attempting to reuse the old dry compound will result in poor thermal transfer and high CPU temperatures, which can keep your CPU from performing at its rated speed.

If you have not done this, power down the computer, remove the heatsink from the CPU, and carefully clean both CPU and heatsink of old thermal compound. Then apply the recommended amount of new thermal compound to the CPU and mount the heatsink accordingly. Monitor temperatures using software like "Core Temp" afterwards to ensure you have everything correct. Avoid monitoring temperatures in the system BIOS as it will not give you the best idea of how your computer is behaving during CPU load.

Concerning your CPU frequency bouncing from 1.5 GHz - 3.2 GHz, this is usually normal behavior of your CPU reducing speed (and power consumption) during low use times, in turn when higher speed is required it will bump up to 3.2 GHz for added performance. However if your CPU is running into thermal throttling issues, you would probably not see it boost to 3.6 GHz. Which could be a result of several issues like: not replacing old thermal compound, having a poorly mounted heatsink, poor case air flow, or high ambient (summer?) room temperature, etc.

Yes i cleaned the cpu and cooler and applied deepcool Z5 thermal paste.Now i will do stress test with Prime 95 and see temp and speed.Im really scared if that used Z77 have somehow damaged my cpu
