Z68 Bios Settings Clarification

post #1 of 2
Thread Starter 
Hey guys,

I'm doing a build this weekend with the Z68 Extreme3 Gen3 and 2500k and looking at threads like these:

http://www.overclock.net/t/1190228/i5-2500k-asrock-z68-extreme-3-overclock-help-please
http://www.overclock.net/t/1155556/what-settings-to-get-to-4-5ghz-on-2500k-asrock-ext3-motherboard

there are some settings I'm unfamiliar with from my previous builds:

CPU Load-Line Calibration: What is this and what's the difference between levels?
CPU Core Voltage: Offset mode seems to be common, what's the advantage?
Turbo Boost Power Limit: What is this and why would I want it?

My current thought is (going for 4.5 ghz):

CPU Ratio Settings: Manual
Max Ratio: 45
Internal PLL Overvoltage: Disabled
Intel SpeedStep Technology : Disabled
Core Current Limit: ????

Power Saving Mode: Disabled
CPU Core Voltage: Find something stable, probably in the 1.3V range
CPU Load-Line Calibration: ????
PCH: Auto
PLL: 1.75
VTT: Auto
VCCSA: Auto

Disable All C States


Thanks

EDIT: Upon further review I see LLC is related to VDroop as I suspected, but on my board it was just yes or no to vdroop, here it seems more complicated (various levels mean partial or total elimination of vdroop and/or vdrop). This was helpful:

though i'm not dealing with a p67

Regarding offset, the advantage in setting this is that the voltage will drop when the computer is in idle. On my Gigabyte board, the CPU Core Voltage needs to be set to normal in order to set an offset. the setting is called DVID for me.

Manually setting the voltage to say 1.3V will always run the CPU with 1.3V.
