Error creating open CL command queue

[Alizel]

hi guys for some reason Reaper and CGminer crash on my new rig.
it has 2 5870's

win 7 x64, I installed 13.1 catalys and it crashes.
I tried 12.8 and I get

Error creating open CL command queue

if I copy reaper from a rig that has compiled it crashes.

what gives?

the machine is an intel skt 775 mobo with a Pentium D, I used to mine BTC with it.

also I just set up 4 new PC's win7 x64 with 5870's fresh 13.1 driver and they hum along nicely.

so why is my Pentium D rig being a dink? ive reinstalled windows like 3 times.



thanks guys.
