I used the bios lightman posted Sapphire_HD3870_fixfan_unlock.bin on my two
Sapphire 3870 and it fixed the 862 GPU Clock Limit but also fixed the fanspeed its no longer at 25percent on both cards now it varies beetween 40-50percent on both cards keeping them in the upper fourties.Hope that helps and I was also wondering does the www.iax-tech.com bioses also have different fanspeed then the original?
