I have four socket 939 processors that consist of semprons and athlons and I have over ten socket 754 processors that also consist of athlons and semprons. I haven't tested them all yet but the half a dozen or so that I have tested all have the same problem.
During "Gaming test 1" the screen goes black right aftter the two fireflies exit the tree trunk. I know from testing on newer systems the screen should not go blank there. But in every test I have done so far the with older systems the screen goes blank at that spot and every once in a while (1 out of every 50 or so) the test will complete even though the screen goes blank. I'm guessing the scores that do complete are bugged runs ???
Anyway, maybe the minimum system requirements should be updated. Just tested this: http://3dmark.com/pcmv/420386 and again I only got one successful run out of 10 this time. Chances are I can run it another 10 times and it wont complete again.
