Tried enabling PLL Overvoltage?

When you say you cant get past 4.1ghz what exactly is happening when you try load up 4.2ghz and attempt to boot into windows?

yeh i have enabled pll overvoltage and tried upping it all the way to 1.9v so far.

i think all the info regarding your questions are listed on the front page as i have been keeping the first post updated with my progress. but basically i cant get the bios to post with anything above 4.1ghz (got windows to boot a couple times with 4.2Ghz but it crashed very quickly), it just freezes when i try save and exit the bios without restarting the computer or anything.

well i have tried 1.45v highest which seems ridiculous for the sort of OC im goig for, i only did that the once though just to see if it worked. My board has LLC levels 1-5. Level 1 has the least vdrop as far as im aware. my setup only seems to like being on level 4 or 5 - I have got 4.2Ghz to boot into windows a couple times and that only worked with LLC on 4 or 5.

to reach 4.8ghz ive changed:

phase control - extreme
duty dontrol - extreme

4.5ghz u need 1.320vcore
for 4.6-4.7 u need 1.35 - 1.38vcore
for 4.8 u need 1.39-1.41

also
dram volt set default 1.5v

your getting confused. CPU PLL Overvoltage is not the same as PLL voltage. One setting is either disabled or enabled, the other is a range amount.

vccsa is one voltage i haven't tried changing yet. i may give that a go. i feel quite uncertain about what safe voltages are so it feels really risky messing with some of them :/
