Help with Prime SP2004

[gcaster]

Hello.

I'm having what I think is a bit of a problem with Prime SP2004 Blend.
I have a Core i5 2500k running at 4200MHz watercooled which hits about 55C at full load and survives the Small FFTs test fine. I run 4 instances of Prime SP2004 to test my system.

However, when I run Blend it all goes a bit funny - I get a little red block stating 'Paging' which stops the tests completing. I've posted a photo below of the screen taken 17mins into Blend showing the problem. Since then another 15mins have gone and only the top right instance has progressed (and only to test 5!).
The bottom 2 instances (started last) haven't moved at all.

Could someone please let me know what's going on. I guess this isn't normal!

EDIT: Another 5 minutes and the top-right instance has progressed through to test 12. Obviously the progression only occurs whilst not Paging.

EDIT: Problem solved. Blend was trying to use all of my RAM for each instance of Prime. Have knocked the amount of memory to be used down to spread all RAM across all four instances.
Sorry for the clutter, got myself in a bit of a fluster there.
