slower core

[turbotoaster]

does a weaker core normally run a program slower

i was bored today so was messing with prime

core 0 is weaker by a long way

started dual prime, core 0 about 10 seconds before core 1 and now core 0 is 1-2 tests behind core 1

is this the same with every body

just wondering

 

[turbotoaster]

running dual prime, if you have a weaker core, it will always fail first, and the other one will keep going

 

[turbotoaster]

if ya run prime, and put the priority higher/lower than normal, does it make a difference to it, just thinking with ya saying 1 core might have to deal with running windows as well

install prime95

then right click the exe and send a shortcut to your desktop. rename this Prime95-1. Right click the shortcut and put a space after the last character in the Target box, and then -A0 (thats an A and a zero)

then right click the original exe for prime and send another shortcut to the desktop. Rename this Prime95-2. Right click on this shortcut, and at the end of the target line, put a space and -A1.

so it should look like this:

double click each shortcut and you should get both prime95 boxes up.

Next you have to go to Advanced - Affinity. This tells Prime to only use 1 instance per specific cpu!

(thx for all of you that found my error in the original!)

Now go to Options - Torture Test...then down to Custom. You will see in the circled box how much memory Prime95 wants to use (this rig has 1GB of memory).

what you have to do is remember that you have TWO instances of this running, so divide this number in half. I always like to give a little leeway, so half of 927MB is 414...so I only use 400MB per cpu (this assures that the system wont over-use the physical RAM and end up accessing the pagefile...keep in mind both cores @ 400MB of memory each is VERY stressful!!!)

open your Task Manager (crtl+alt+del) and you'll see two physical cores in the cpu box...click OK on one of the primes, and you will see 1 core go up to 100% use.

click OK on the second prime and you will see the second core go up to 100% use.

I never use memtest coz it means floppys and dos and i don't do either of those...
Unless theres an easier way?

there you go, you can run memtest though windows, dead easy
