Secret Rabbit is probably the most processor-intensive program I've ever used when you use the option "sync best." It totally eats up my 2.4 GHz P4 and crashes my PC eventually at higher sampling rates, especially higher than 96kHz.One trick is to lower the "sync" options a notch or two below "sync best," which greatly reduces CPU usage. The next notch down sounds basically the same to my ears.

My AMD 2 GHz XP system happilly upsamples to 2496 with NO issues on sinc best. May be you have background services running.
is when I run into problems; unfortunately, 176.4 KHz is the only rate worth running IME.If you keep an eye on processor usage via Device manager, even with Sync Best 176.4 KHz, processor usage shows only 70-80% most of the time, but if you use it long enough, a spike in usage (for whatever reason, foobar or PC) can crash the PC.
Hey F,My 1.8 amd can do that too. It is when one jumps to 176 or 192 that things come unravelled.
Well, my 1.8 ghz machine (not my audio pc) cant go higher than 96, no matter what setting.One day I hope to get my 3.2 ghz pc and try it with that, but right now, the audio rig has the fanless 1ghz pc, and it doesn't do secret rabbit that well, i think 48 is the highest it can go.
I believe my older Toshiba laptop has 1.4GHz Pentium. It runs 24/96 fine with SRC. Have you turned off everything else? Try looking at running processes to see what is hogging the PCU cycles - use CNTRL-ALT-DEL.
Thanks. It has been a while since I moved, but the system is not up and running.I think though that I rmember trying to track things down, and nothing else was hogging any resources, just Foobar. But, I will look again.
Besides eac and foobar, there are no additional programs installed, and I have stopped as many services as I konw how to. But, this is good advice, and I will look into it.ALso it just dawned on me, but my pc is not amd or intel based, but uses a via processor. I remember reading that that cpu is not good at multi video apps, so maybe its performance is skewed??
It's 176.4 or above that REALLY cause problems!
