First off, hello. I just joined this forum so I would like to start up a few different discussions on things I have had difficulty getting input on before.
I also like to utilize C1E, C&Q, Spread Spectrum, and C6 as I like that the CPU mostly shuts itself down while in a idle state.
I would like to see if any of you have attempted to run default voltage overclocks, while having Turbo mode running in tandem. It is one of the things I have been testing out with my FX-4100 as while most programs can utilize 4 threads or more fairly well these days, there is still a handful of programs which sadly only execute on a single thread, or perhaps only two.
In the name of performance I want the best of both worlds, I do not like running high voltages for 24/7 overclocks so I began playing with the turbo function a little more since its inception on the AM3 E0 stepping.
Now I can gain marked improvements on my FX-4100 in single threaded programs by running it at 4400mhz 1.325v / 4800 1.4 boost state. There is just one catch, on my board, or more specifically on my board and chip combo, in order to use a turbo state greater then 1x multi I need to use APM (application power management).
This is where I run into the negative effect, while everything is stable and does its job correctly, i lose out on the multithreaded performance a little as while the CPU is under load, APM will randomly throttle one of the FX's integers down from 4400 -> 3300 then right back up, and will do this randomly across all of the threads while working on the work load.
But when I get to the single thread, or dual thread workload two threads will idle at their proper 1400mhz while two buzz away at 4800mhz
Findings.
CPB/APM Off @ 4400
CPB/APM On @ 4400/4800
CPB/APM On @ 4400/4800 (with multithreaded loads causing 3300mhz fluctuation)
Anyone else test something like this out?
