DS4 overclocking help!

[richieboy]

So, i have been following the two threads for the DS3 and DS3/DS4/DQ6 owners about overclocking etc. I have increased voltages as mentioned, set other settings, increased memory multiplier and host frequency etc all as stated...

But everytime i put these settings in, i save and reboot and after posting i just get a flashing underscore up in the top left of the screen and nothing else happens, i just have to turn off manually...

What am i doing wrong, can anyone help?

I have the latest BIOS etc

Ok it seems that disabling CPU Enhanced Halt (C1E) and CPU EIST Function gave me this problem as when i enabled them all was fine.

Here are my results so far, with the system thingie (!) at 300 and the memory multiplier at 266...is this any good? Im using an Arctic Cooler 7 and idling at around 30c at the moment in Windows.
