Orthos X for quad-core testing?

"In order to simulate a 100% LOAD to all four cores I chose Prime95 v25.5a. This and Orthos X are the only two programs which currently support Quad core testing."

Hmm, "Orthos X". Where can I find this? Sounds new to me.

I can' find it either....I see where people will say Orthos x 2 or x 4 for the number of cores they are running but I couldn't find ortho X as a name of a program....

You can use regular Orthos to stress 4 cores.

Orthos will stress dual cores basically.

You can run two instances of Orthos at one time.

To run Orthos on four cores:

Open up two instances of orthos but don't start them, go to task manager (ctrl-alt-del), under processes find the two Orthos, right click on one of them, you'll see at the bottom menu 'set affinity', click it and you can choose which cores to run that instance of orthos on, set one instance to run on CPU0, CPU1, then the other on CPU2,CPU3

then run them, check task mgr under performance and you'll see 100% usage for all four cores.

simple to do really..

yeah, duvie larry, run two instances of orthos at the same time, duh

why not just p95 v25.6? it tests all 4 cores + lots more ram.

and isn't orthos and p95 the same test essentially? why bother running 2 versions of something when 1 is enough.

 

[dampeal]

yep:

32bit- http://mersenne.org/gimps/p95v256.zip

64bit- http://mersenne.org/gimps/p64v256.zip

not really...

ive had stress test fail prime and pass orthos. After i noticed it a lot on B3 quads i decided to give up on orthos. Its a great program, and should be enough to keep you gaming stable, but i WCG, and if you F@H or WCG, you know what stability means.

But in General, i wouldnt look at orthos anymore. Prime25.6 should be the program you look at.

yea i mainly test with p95 25.6 right now and a little bit of HCI memtest

Yeah, what dampeal said. Use version 25.x of p95 and be sure you enable the 'round off checking' or else it won't report errors.

I don't think that's true. If you select torture test, it seems to enable round-off checking automatically.

Torture test IS made for testing machine stability, so what you said makes sense.

Yes, I think it does report errors without round-off checking; however, when I used round-off-checking, I got a different error message about there being a hardware problem. So either round-off checking is more intensive, or the error message was changed.

Anyone have more information?

Dude. a little advice. DO NOT call out Duvie. He will eat you.

I dont need to...I run prime95 new version and it runs 4 cores for me automatically...

I remember the days when I ran separate instances....I use to have to run 4 instances of F@H before they cam out with an SMP client...
