Still modern?

Wow, no one took the time to answer his last question? I'll give it a shot.

In terms of your percentage problem, it might not actually be a problem at all. I'm assuming you're using a version of Windows, which I'm unfortunately not familiar enough with to know how it deals with cpu percentages. But, to explain what I THINK is going on...

You have a cpu with 2 cores, or sub-cpus. So, you could either count the whole cpu as 1(100%), or you could count each core as 1. If you count each core individually, then you get the interesting situation of a Task Manager that can list a process(running computer program) as using more than 100% cpu. Myself, I have a Linux box, and I've seen another program(it was the distributed.net client) running with a listed cpu usage of 395%. It was because I have a quad-core and it was rather efficienty using all 4 cores.

In your particular case, I think the computer program considers your entire cpu as 100%. If you're running 1 exponent per core, then each core is at 100%, but each program is only using 50% total power because it's only maxing out it's 1 core. So 1 core is 50% of the available power, and you have 2 cores in your computer, adding up to 100%, or a little less because it has to take care of other stuff at the same time.

I've probably totally confused you since you're foreign, but I suck at explaining stuff. Just didn't want the thread to trail off without an answer.

FYI, Windows never has CPU percentages go over 100%. On a dual-core system like the OP's, it will work like this:

-For a single-threaded application (like v24 Prime95) using one core, Task Manager will say that application is using 50% CPU. Likewise, if you have two concurrent programs using one core each, it will show each using 50% for a total of 100% CPU utilization.

-For a multi-threaded applicaton (like v25 Prime95, the current version that the OP has) using both cores, Task Manager will say the application is using 100% CPU (or close to it).

In the OP's case, his setup is like the second case described above. He has Prime95 set to run both cores on the same exponent, which should produce a figure close to 100% for Prime95.exe in Task Manager.

Demondog11, if I'm understanding you correctly, you're seeing a figure of 50% for Prime95.exe in Task Manager, which would indicate that Prime95 is not configured the way you want it to be. Can you post a screenshot of Task Manager (sorted by the CPU % column) to confirm this?

Thanks again for the answers... (it is me Demondog, I now registered^^)

I had the computer work on a 100M+ exponent which I then had to sdee was useless (didn't want to wait till August 2022 just for LL Test). After I unreserved the exponent I made both Cores work on one World Record-size. THat'll just take about a 5weeks now that I'm done with all factoring,P-1....

It now is working at 100% (99%) again, so I guess something went wrong when I configured them 100M+worker. Since the problem is solved I think the thread can be closed?!?

Thanks to all helpers (and yes I did understand all the explanations ;) )

World Record-size of what????

I think this is rather obvious given the context in which "world record" appears.
