Hi everyone,

So I finally got Scope working with my AMD dual-core CPU in single-core mode. However, I'm really disappointed I can only use half my CPU. I tried making the Scope software use only one CPU in the taskmanager, but it still crashed because that didn't affect the drivers. Is there a way to make a driver process use only one CPU as well? That would enable me to use Scope in multiprocessing mode.

Thanks in advance,

Shayne

Either of these might work:

Earlier, you disabled hyper-threading, correct? I found HT to be bad voodoo, but I'm doing fine in general with dual-core.

Ah, you can do: CTRL-ALT-DLT to pop up the taskmgr, and go to Processes and highlight the process and right click... affinity is right there... nice.

Scofield, that Microsoft IntFilter says it's a Windows 2000 thing, and I have Windows XP. I'm not sure if it would work. However, Process Explorer looks promising, and when I get to my audio PC later today, I'll check it out and let you know if it fixes my problem.

Stardust, AMD processors don't do hyperthreading, and you can't turn off dual core in the BIOS. I had to do it in Windows using an obscure option. Thankfully, I can revert it back to multiprocessing.

Thanks for your help,

Shayne

Update: I just tried Process Explorer. It tells me lots of things, but it doesn't have any CPU affinity options that TaskManager doesn't have. SFP isn't causing the crash apparently, it's some DLL or device driver. It happens when I change the ULLI setting.

There's nothing that can set the CPU affinity for dlls and such?

What mobo is that?

EPoX EP-9NDA+ is what I have, BIOS upgraded.

/INTAFFINITY
Directs the standard x86 multiprocessor HAL (Halmps.dll) to set interrupt affinities such that only the highest numbered processor will receive interrupts. Without the switch, the HAL defaults to its normal behavior of letting all processors receive interrupts.

in boot.ini


setaffinity in when win have booted?

I have not had the time yet....

I have a feeling it might work though ...

And just to repeat from elsewhere, the freeware/shareware app "PowerStrip" has a feature for automatic application affinity setting. http://www.entechtaiwan.com/ps.htm

Not sure if it can get down to the driver level, but probably good if you want to force two apps to live on the same CPU automatically.

a bit tricky, but works
