Dual Prime won't hit 100%??

Recommended Posts

Hi, here is the spec of my computer

 

AMD 4200+

FDI Lanparty Ultra-D (24/11/05 bios)

2x512 OCZ dual channel performance PC3200 RAM

Gainward Goes like hell 7800 GT

300 sata maxtor drive

audigy sound card

hiper 580w type-r psu

 

When I oc to 2600mhz dual prime won't hit 100% cpu usage. Anyone know why?

it's always on about 53% when I check with ctrl+alt+del.

 

I am at the first part of my OC process. I follow the OC guide here and is on the part to test the max CPU speed. superpi and occt and all 3dmark passed. prime runs too, but i don't know why it isn't using all the cpu resource.

 

I am running dual prime in 2 diffrent folders.

 

Please help....

Check your custom torture-test options. You might be allocating too much memory, causing it to spend more time paging than on CPU. There is a link at the bottom of the OC guide that tells you how to setup dual prime95. Make sure that the mem amount you use is less than 50% of physical memory for each core.

 

You might also have affinity set wrong.

Yeah, make sure that each instance of prime95 is running out separate cores (check the affinities). Using different folders isn't going to cut it.

According to your sig you have 2*512 memory..

 

Use custom test and allocate 400megs to each instance.. You make 2 different instances by making 2 shortcuts and add -A0 to the first and -A1 to the second in the command line option..

 

800 megs pr. instance is for 2gig rigs..

 

P.S. My rig hits 63% load with blend tests started on both cores - so yo HAVE to use custom test..
