help with GA-X58A-UD3R (rev2) oc settings

[DeathEvil]

hey all,

I want 2 profiles in bios: 1 for everyday use, and 1 for benches/gaming/folding.

I already got the one for everyday use:

15x200 all voltages stock except cpu
i7 920@3Ghz undervolted to 1.008Vcore with HT on
memory at 1600mhz
cpu load line-auto
all energy saving enabled

all prime stable and never breaking 59C even on hottest days. with these settings the vcore stays the same during load and idle (1.008), so I'm happy with that setup.


now the performance profile:

20x200 all voltages stock
i7 920@4Ghz running at stock vcore (1.275 in bios is required for prime to be stable) with HT on
memory at 1600mhz
cpu load line-auto
all energy saving enabled

all prime stable and never breaking 81C on the hottest core even on hottest days. Now, I would love for this profile to change the vcore between idle and loat but for this I need to mess with dvid which results in a unbootable windows.

I need help setting up dvid/load line calibration so when I'm in idle the clock jumps back to 12x200 and around 1vcore and when in load to jumps back to the stock vcore (1.275 in bios).

any input is appreciated,
DeathEvil

My first thoughts are that you're almost trying to reinvent the wheel. A lot of the voltage and powersaving type options are already built into the CPU or can be leveraged using inbuilt software like DES2.

Your everyday use setup for example, is wasting power by not dropping voltage on idle. Rather than setting a fixed voltage why not supply an offset and enable DES? This should enable the CPU to power down to ~0.8v or less when idle, and DES will also shut off power phases and undervolt chipset and memory etc. components for more power saving.

DES might also help with your performance profile, if supplying an offset in bios is causing instability you can use DES to help save power where it can. But I would concentrate on trying different values to get the fixed voltage + offset stable if you can.

I would not use LLC as a means to obtain higher voltage at load, as it will cause an overvolt when the load finishes.
