Hi,

Originally my 4530s had a i3 and I've put an i5 2430m in it.

I updated my 4530s to Yosemite using the clover update, worked fine, but very very slow. I ran DPCI Manager to check
the P states and it told me there were errors. The log show throttling to 1Hz, 2 Hz etc

I used the probook installer clover edition, and installed the config, DSDT, SSDT etc from there, so I dont understand what
went wrong.

thanks
Jon

The throttling errors you see from DPCIManager are normal and unrelated to your issue...

It is the other output that is important (pstates). What is it?

Download patchmatic: https://github.com/RehabMan/OS-X-MaciASL-patchmatic.
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,
Code: 
rm -Rf ~/Downloads/RehabMan
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Post contents of Downloads/RehabMan directory (as ZIP).

Also, post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

And output from:
Code: 
kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
 
DPCI Manager gives a warning alert - DMIDecode Error Detected.

Looks fine.

Test your pstates with AppleIntelCPUPowerManagementInfo.kext.
 
Im not sure how to test the p states with the AppleIntelCPUPowerManagementInfo kext. My problem was my
slow speed, borne out by the Geekbench test result of 626 single core and 1476 multicore. These should typically
be 2200 and 4700 so there is something really wrong here.

Yes, which is why you need to test your pstates.

Maybe you should do a fresh install being certain to follow the guide exactly.
