the i7 3820 oc tweaker in bios doesn't preserve the multiplier setting
I own an ASRock Extreme4 motherboard and I'm just curious about what this outdated chip can achieve. Using 44x100 with AXTU and adjusting the offset voltage worked fine, but my multiplier is fixed, so I entered BIOS and tried 36x125 to reach 4.5GHz, setting the fixed voltage to 1.35 just to test. If I attempt anything above 36 with a 125 bclk, it immediately restarts at 4.5GHz, even though my BIOS claims 37x125. This is my first night experimenting with overclocking from BIOS, so maybe I overlooked something obvious?
Temperatures during Prime95 at 4.5GHz were acceptable, but if the motherboard is restricting me to 4.5 or similar, I should revert to 4.4 and adjust the offset voltage. Thanks in advance, I hope I didn't ask a too simplistic question.
I only changed the OC in the bios. Why are you adjusting the base clock and not modifying the multiplier in the bios? Do 45x100? I meant to do 4.4x100, but I couldn't reach that without hitting the max overclock I could due to BCLK. Anyone above 4.5 GHz is at 125.
