AMD A8-3870K & GIGABYTE A75-UD4H LN2 overclocking by froxic (WRs inside)

[froxic]

I dont know, but more voltage didnt help at all. I adjused frequency of only one core by PSTcheck (for validation and spi/hexus runs). With all cores at this speed it will be much worse.

More strange is that I have some scaling problems on Windows 7. Tried 12.2, 12.1 and 11.8 drivers - no difference.

LN2 @ 5000MHz: 1778 http://hwbot.org/submission/2265316_...50d_1778_marks
WC @ 3600MHz: 1635 http://hwbot.org/submission/2255998_...50d_1635_marks

LN2 @ 3900: 1865 http://hwbot.org/submission/2203006_...50d_1865_marks (by Iron)

I have +- same efective RAM (clock/timings ratio), higher GPU and CPU clock. If drivers doesnt do the trick... It must be of some sort of throttling. But on the other side, wPrime 1024M on 5Ghz runned smoothly (without throttling). Vantage was same and in Heaven I received same points (at 5.2GHz) as on WC (3.6GHz). With 3DM11 i tried even lower clocks 4.6/4.8 but it was even worse. Any thoughts?
