AMD 5500, undervolt question..???

[Volanaro]

hi guys so im a old school overclocker from intel, im used to voltage manual setting not offsets. i have no idea how they work, now i upgraded from a 6700k -> amd 5500 im trying to undervolt it, i can do it in the amd master program, and its stable at 1.087v easy as i can pick the volt i want to set, now in the bios () it only gives me a offset for the voltage i change, and i have no idea how it works. do i need to put an offset of,  0.170.. or something? i honestly have no clue

 

cheers

In BIOS, PBO, manual Curve Optimizer, set all to -30

If you have crashes put best cores to -20 then -15

ok thanks ill have a look, i have the asus b450 plus ii, so what dose this all mean? -30 etc etc

i personally have no clue when it comes to dynamic overclocks so ill just give some reference for manual voltage

 

Set 1.15v medium/no llc, see whats the highest max stable freq you can get, then proceed to do the same for 1.25v and 1.35v

 

Once voltage scaling starts to drop off try for a middle setting like 1.3v or 1.2v

 

This will give you best v/f, lowest voltage for the highest freq, basically you are searching for the optimal setting that is right before you hit diminishing returns

Itll be worse than Curve Optimizer if OP is going to run stock boost clock. But yeah, that is the old school undervolt for ya.

Optimum Tech made a much clearer explanation on what PBO does, and how to undervolt with it.

welli did a undervolt ov - 30 and for some reason when i booted i was running at 1.5v ?

Are you using the latest bios?

ahh i needed to disable the pbo limits seemed to fix the undervolt,
