hi people, I want to ask someone who knows which is the proper setup in bios for b450 tomahawk max to boost maximum my cpu r5 3600?
which settings in bios do I need to enable or disable (smt, pbo etc...)?
Iam totally noob what that all settings are for.
thanks 😊
First, if you haven't, is update BIOS to latest and get the AMD chipset driver package from the AMD web site and install it.
Second is set the following to ENABLED in BIOS: AMD Cool n Quiet, Advanced C-States, Processor CPPC and CPPC Preferred Cores. You don't want to leave them in AUTO because many times BIOS's interpret that as DISABLED.
Get HWInfo64, latest version, and set the sensor polling period to 500 mSec's. Now run a lightly threaded task, something like a Defender Quick-Scan works for me, and monitor the core multipliers (create a graph on the desktop for each of the 6 cores). You should see several cores, maybe all but never at the same time, boosting to rated clocks.
To get higher and longer boosting you'll have to play with PBO. It's not exactly obvious but start with enable it and increase some parameters to higher values: try setting EDC and TDC to 230 and PPT to 330. Sometimes, a very SLIGHTLY lowered VCore (do it with offsets only) can also help. This probably won't help so much with max boost clocks but instead with holding a higher mid-range boost clock when the processor is heavily loaded. That helps more with long-running benchmarks (like CB20) and real-world processing tasks, especially so if you also have good cooling.
Those settings work well in most cases but with Zen 2 PBO needs a lot of experimenting to get the MOST because what works best depends very much on specifics of your CPU and your motherboard. There is no one setting that works for everyone to get the best boosting and in the end the "seat of the pants" performance difference will probably be very small, unnoticeble even.
There is also an AGESA (BIOS) "bug" that can be exploited, a whole forum thread on it can be read here:
