@DrDave:
Die Spannung der HD 5850 ist noch @stock. Da es sich um eine Powercolor HD 5850 PCS+ handelt, bedeutet @stock hier bei 1,125 V.
Mit Trixx kann man die Spannung inzwischen trotz analoger Spannungswandler einstellen. Ob das gut klappt kann ich noch nicht sagen. Ich möchte zunächst das Limit mit Standardspannung austesten.

-> mehr CPU-Power steigert also nur noch die Physics Score
