[SOLVED] No need to raise FSB on AMD FX black edition chips?

[GWARslave119]

I can't remember where I read this at...it's in my history but will take a bit to find but is this true that you don't raise the FSB speed when overclocking an FX black edition chip?

FSB overclocking was provided for owners of the non-black edition Phenom/Phenom II processors as all FX processors are mulitiplier unlocked. So for FX, there's no need to change FSB if you can simply change processor multiplier. But you can still do so if you're fine-tuning an overclock to get the final two or three MHz for both CPU and memory. Not that it results in meaningful performance benefits but it was something to tweak in idle times.

You can OC FSB but it also overclocks RAM and PCIe and with it SATA so those parts may not take it kindly.

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

Was kinda wondering if overclocking my ram would get any useful performance out of it, but I read it's best to overclock with 2 sticks and not 4

There's no enough room to OC from 1600MHz as latency would also go up negating positive effects on memory performance but yes on AMD it's difficult to OC memory or run it at high speed with both memory channels used

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 running at 4ghz all throughout, I was thinking of doing a per-app overclock with AMD Overdrive, but the AMD Smart Profiles elude me. I read a long time ago a post that said:

check CPU Core affinity 1-3, leave core 0 unchecked
check Boost State
Set core Voltage to 1.5v {careful w/ this one! - make sure you are not over volting}
Set P-State to P0
Core Multipliers I leave at default as I have increased Mult. via Bios. {+4}

it's from https://www.overclock.net/forum/10-amd-cpus/673657-overdrive-smart-profiles.html
but I don't remember if that 'profile' was to have said program set for multi-core optimizing or if that was some other forum. The setup for a Smart Profile is

The Predefined Rules section is blank/doesn't work. So if I want to only have my computer kick into higher gear when I'm playing a certain game, any idea how to go about that through this. I'm not familiar, and I tried looking it up, with the different P-states as well, the dropdown menu has P0 thru P4

Edit: Oh and where that guy says set Vcore to 1.5v, I'm sure that's for an older amd cpu, I can run with a 20x multiplier in bios (4ghz) at around 1.3v or so
