3.44 GHZ Q9400 Slow Dolphin Framerate

[blkhockeypro19]

Hi there,
I bought a q9400 at 2.66ghz. (FSB 333 x multiplier 8)

I bumped up the voltage and FSB till I was stable with safe temps at 3.44 ghz. (FSB 430 x multiplier 8)

I then set my RAM multiplier to 2.66D, which resulted in a RAM frequency of 1143mhz. (It is capable of running up to 1333mhz.)

These 2 changes resulted in a FSB : DRAM ratio of 3:4.

Finally, I have an 8800GT at stock speeds.

So the real problem:
Before over-clocking, I was getting between 20-30 FPS in Super Mario Galaxy.
After over-clocking, I am getting the exact same numbers.
Is something bottlenecking another component? I understand hardware can only go so far, when the software still hasn't been perfected, but I've gotten to a decent over-clock, with absolutely no performance gain. Any idea why?

What is the % of use of the four cores ?

Cores 1 and 4 are at about 60-85%
Cores 2 and 3 are at 30-50%

thats the problem , dolphin should only use two cores ( maybe three with the DSP thread )

Tell me, are you running Dolphin optimally?
Dolphin runs fastest when you use the Direct3D9 plugin, with EFB Copy set to Texture, having the latest revision helps too. (R5164)

Alright, should I just use task manager to set the affinity to cores 3 and 4 or something?

And I am using the opengl plugin because direct3D9 causes a 5-10 drop in FPS. I would like to use directx, but the performance just isn't as good for me.
I've read that opengl works better on nvidia with dolphin, and directx works better on ATI with dolphin.

hmm,

enable dualcore
enable lock thread to cores
disable stepspeed in your BIOS
see if enable DSP LLE on thread makes any difference

most of the above comments are fairly useless. Dolphin won't benefit from four cores but the way windows works is that the workload is distrubuted accross the cores. (not evenly though.) Just turn of efb to ram and change it to efb to texture, enable dual core but disable idle skipping if you want framelimit set to auto. It syncs the jit and graphics better.

I'll try those suggestions in a few minutes. Also setting affinity to 2 cores works, but decreases frame rate by 10FPS.
EFB to texture is already enabled, dual core is enabled as well. I will try to disable idle skipping and set frame limit to auto.

What are everyone else's FPS on SMG? Using native resolution or your display's resolution?

I get about 80fps with an i5 750 at 2.4ghz. It seems your hardware is not the issue and that the problem lies in your config. You're using the dx9 plugin right?
