3D Mark Ultra problem / OCing

Ok so here goes. My first 3D Mark ultra run ...

5071

And my second...

4202

What I don't understand is the 2nd run, I had increased all the clocks, cpu from 4 -> 4.3 And an extra 100mhz on the core and memory clocks. I had also changed my RAM in the BIOS from 1333 to 1600. (Though 3D Mark won't show that for some reason). highest CPU temp = 54 deg C Highest GPU temp = 75deg C.

Anyone any ideas why?

Using these settings on the standard firestrike got me my highest score yet, 16K and it was perfectly stable. Thanks, J.

Ignore 3D mark it makes little sense.

I ran 3D mark today with my r9 270 and it wasn't showing the right clocks... Did the same with my GTX 780 ti.

Try another benchmark, Heaven or something else.
