Maybe you should ask this on the MSI Forum!
I know I had issue testing both on the same computer, I found it best to uninstall both and delete any profiles and then install and test one at a time.

might want to try CCleaner for registry errors oh and make sure nothing is set to auto in msi afb

Ccleaner will clean registry errors. My advice would uninstall both AB and precision. Not sure what you  mean by reading the same, There sensor algorithm/ and reporting rates might be different.
1:uninstall both through control panel.
2:Run CCleaner --> registry tab--> Scan for issues --> fix all issues --> Backup registry ( JUST IN CASE)
3:Restart after Cleaning
4:Download both, run EVGA first... Restart computer.
5:Run MSI afterburner. i would restart again.....
DO NOT DO THIS IF YOU DON'T FEEL COMFORTABLE THIS WILL BREAK YOUR SYSTEM IF NOT PERFORMED RIGHT.. RECOMMEND SETTING A RESTORE POINT!!!!!!!!!!!!!!!!!!!!!!!!
If running win7 go to globe/start menu. type in the bottom "regedit" hit enter
you will see five choices
expand as follow
Afterburner and percisionX16 should be gone.. After running CCleaner
1: HKEY_CURRENT_USER--> Software--> MSI--> Afterburner ONLY!!!!! delete Afterburner
and any EVGA folder. right click on HKEY_CURRENT_ USER select collapse This return the column to normal
2: Next go to HKEY_LOCAL_MACHINE--> Software--> Delete any EVGA
If their are entries to MSI or evga.
As for Overclocking look up your motherboard that is where i would start.
Hope this helps if still having issues :-)
