FSB overclocking was available for owners of the non-black edition Phenom/Phenom II chips, since all FX processors have unlocked multipliers. This means you don’t need to adjust FSB if you can just modify the processor’s multiplier. However, you can still make adjustments if you’re fine-tuning an overclock to achieve the desired final speeds for both CPU and memory. It doesn’t significantly boost performance, but it can help with idle times.

You can change the settings for FSB but it also increases RAM, PCIe, and SATA speeds, which might not be well received.
Ok thanks, I was running on a x20 multiplier for awhile but wasn't sure if that was ok. If you do the OC tuner in the bios it does the fsb and drops the memory from 1600 to 1066
2 steps forward, 100 steps back lol... ok so I'm thinking of going back to trying out AMD Overdrive again, even tho the support for it seems almost non-existant, for on-demand overclocking/on-demand performance, instead of having my computer overclocked all the time. Not sure how familiar you are with the FX chips or associated chipsets/bios. Actually lemme run this by you before I go into the Overdrive thing...and actually yeah I just read
https://www.amd.com/en/technologies/amd-overdrive
has been discontinued. So in my bios I have:
The multiplier was at 20 but I set it back to 17.5 hence the speed difference
the timing section i'm going off an xmp or whatnot profile, which is slightly different than the DOCP profile, so everything in there is manual. I did change on this boot the command rate to 1T, not sure if that will do anything drastic. The driving control section is whatever the system decided, but I manually inputted the values after Auto picked it's thing prior to a reboot. Now I was setting all the voltages in Manual Mode like right there, and
but if in Manual Mode, then
shows, as opposed to Offset Mode which shows
so not sure if it matters what mode I'm in. And I also don't get the difference, if in Offset Mode, the Cool'n'Quiet option Disabled By CPU vs. the option Always Disabled. Then there's the fan control
which I remember changing it to Manual Profile a year or 2 ago for some reason I had read, before that I had it set to Turbo. Or should that even be enabled at all? Lastly there's the memory config which has been a while since I've changed
So instead of maintaining full 4ghz performance constantly, I considered applying a per-app overclock using AMD Overdrive. However, the AMD Smart Profiles didn’t seem to be accessible. I came across a discussion that suggested:
- Check CPU Core affinity settings (1-3, leave core 0 unchecked)
- Adjust Boost State
- Set core voltage to 1.5v (be careful not to overvolt)
- Choose P-State as P0
- Keep Core Multipliers at default since I increased the multiplier via BIOS (+4)
The guide came from https://www.overclock.net/forum/10-amd-c...files.html, but I’m unsure if it specifically mentioned a program-based multi-core optimization or another forum context. The recommended setup for a Smart Profile is as follows.
