Stressing 4 cores in vista

[WoodButcher]

From what I have read many of you are testing your quads for stability with orthos. I'm running vista and can't seem to set the affinity for orthos to run all 4. This screenshot shows by core temp, task manager and performance monitor I'm only working 2 cores. Toadster suggested Boinc and it works great for stability testing, stresses all four cores [I ran about 8hrs @ 3.4, my avg. temps 43-44c] but this is not built for testing, it's time log is cumulative, you can't change the tests in order to stress different components, ram, cpu. Can the affinity be set in orthos or prime to run in vista?
Yes, I tried Prime as well, in xp I could run multiple instances but vista won't let me, I'm so ashamed ,,, I feel inadequate,,, help?

Run two instances of Orthos and set the affinities. Problem solved.

Nothing should stop you from running two instances.

That's an older beta version. Apparently, 25.3 is out now:

Forget Othos. The new Prime95 25.3 replaces it!

Orthos is a pain to set up with four cores. Prime95 much better.

I did get orthos going on 4 instances. I used orthos sp2004 from 4 different files. I find that vista is such a memory hog that orthos fails quickly. I had to slow the cpu to 3.0 to run all 4. I have 2G ram installed, maybe tommorrow I'll add 2 more and see how it does.

Hmm, interesting... my version of Orthos stresses two CPUs with a single instance. I have no idea where I got mine, but it says ORTHOS BETA at the top. Cool. The "About..." says v041.110.18. I don't know if it matters, but maybe that will work better than four instances of Orthos.

All orthos copies that I know of stress two cores at once.

I think that vista is not the reason the tests are failing, it is probably running 4 copies of orthos.

The "sp2004" runs 1 core at a time , the newer does 2 but I can't choose the affinity,
In the screenshot I posted here note that the task manager shows only 2 cores stressed, the two running small FFTs, the other two are running blend. The two guages are vista toys the little one being the memory usage. 2gigs of toast.

If you make four separate copies of prime95 (i.e., in four different folders), then you should be able to run them all at once.

I did try that and for some reason each time I opened a new instance from the next folder the original would come up. I tried it when prime was running and not. I'm sure there are command lines to make this work but I don't know how to use them.

Just make 4 shortcuts to prime 95, or use the new prime95 25.3 (which stresses all 4 cores in one instance).

If you want to use the older prime95, make the 4 shortcuts to the same exe on your desktop or whereever. Right click on each shortcut and select properties. In the target window, add -A0 to the end of the target for the first one, -A1 for the second, -A2 for the third shortcut, and -A4 for the fourth.

You will still need to set the affinities in the task manager. CNTRL+ALT+Delete, and go to processes. In the list you will find the 4 copies of prime95. Right click each one and select "Affinity". Give each one it's own single CPU.

Of course, it is easier to just use Prime95 25.3, which will do all of that in one exe. You can download it Here.

Beauty! thanks, adair I appreciate your help. Sorry I'm such an ignorant fool but with help like all you guys offer my ignorance will fade and I'll just be a fool!

My friend has a version of Orthos that auto-detects and spawns worker threads for a quad-core CPU automatically! He doesn't remember where he found it, and I can't seem to google it sucessfully.
