How can I tell If both cores are being used

post #1 of 7
Thread Starter 
I followed this guide http://www.overclock.net/faqs/106983...re+stress+test to run 2 separate prime95 programs but I don't know where in the task manager it shows 2 cpu's. When I launch both prime95 apps, my cpu usage goes to 100%, but task manager shows both instances using 50 a piece. Does this mean that its working both cores?

100% means both are being used, if you run one prime95 it will only go to 50%

I dont have dual core so I'm not sure, but selecting one graph per CPU, at the windows task manager would do the job better.. tUDJ is right as well..

Download sp2004 Orthos.

it loads both cores 100% with the same test as prime95, and it's got a slick little GUI.

Trust me, you won't regret it.

and this WILL load them both at 100%.

Thanks that is a LOT more user friendly. I think I'll ditch the Prime95's now.

Your welcome man.

Hope it makes life easier (I know it REALLY helped for me when you have to keep doing it over and over again)

when it is showing your cpu usage it shows it as a total adding both cores together. so 100% means both cores are being used but when you go to task manager and that 50% is being used that means 50% of total CPU power or 100% of one core which leaves one core free to do what it wants.
