Prime 95 Strange Behavoir

[FrostyAMD]

running prime 95 64 ver 26.4 on Asus Pro P8P67 with 2600k and Patriot PC1500 1866MHz ram running 1600MHZ with 9-9-9-24@1.6. Start the program and all cores show progress except core 3 (never shows any progression stays at first test) when I stop all workers says test completed with no errors. First time seeing this happen. Any suggestions ?

Check the bios, make sure all cores are active, I think under CPU configuration or so.

Open task manager, see how many cores actually show active
