ASUS UEFI Steps
CPU Vcore –
Offset is advised if possible with a recommended value being .0165-200 depending on frequency needed (NO LLC is advised) as the VID automatically scales with the multiplier. In most situations manual VID will be selected and utilized with the VID needing to be defined for the frequency being attempted. For initial testing to ascertain CPU frequency and vid scaling alignment set your Vcore to 1.410 (Manual / LLC Medium) if the CPU is able to post and boot at this value the quality of CPU is solid and should allow for flexibility in the vid needed to operate at higher frequencies. If at all possible reduced vids are advised as you will have significantly lower power draw and heat output.
Manual vid selected with vid defined at 1.410 (Medium LLC)
If using an Offset vid do not use any LLC this helps to ensure superior efficiency and reduced voltage to the CPU at idle and load states. With a value of .200 and no LLC and all Cstates active (C1E-C7) idle vid should be approx 1.00x with load vid dropping approx to 1.432/1.440.
CPU VCCSA Vid –
This voltage is key to ensuring superior DRAM scaling as well as stability in 8 DIMM and 1600+ configurations. In most situations a fixed value of 1.100 is advised and not advised to exceed unless need for post/boot and memory load. To minimize aggressive overvolting of the VCCSA a setting of regular for the LLC is recommend to align with the 1.100 (manually be vid being applied). Should additional VCCSA voltage be required a setting of Extreme is advised prior to manually defining considerably higher levels like 1.200. In internal testing IMC frequency scaling has seen considerable range varying from 2133 up to 2700 (with varying support for those frequencies under 4 DIMM or 8 DIMMs loading). In some situations and some IC it may be required to utilize 1.200 vid.
CPU Load Line Calibration –
This setting helps to compensate for droop for the vid defined for CPU Vcore (whether it be Manual set of set via an Offset)
A value of medium is advised for most 1 to 1 voltage configurations. Be advised that at higher power draw loads which vary from application to application as well as synthetic stability tests, High may be a preferred setting to account for potentially higher droop and more consistent vid being needed to ensure stability. LCC settings exceeding High are not advised unless under extreme or exotic cooling.
CPU Current Capability –
This option is key an ensuring OCP trigger point is not hit when overclocking. This value needs to be defined dependent on the load of applications and potential stress tests. Overall a recommended for 4.6GHz is 120% with 4.8GHz and up are advised to set at 130%. 140% is red due to the load at that stage would be extremely high and can potentially exceed rated components parameters operating margins (heat , power etc).
VCCSA Load Line Calibration –
This setting helps to compensate for droop for the vid defined for VCCSA (whether it be Manual set of set via an Offset)
Advised to be set to regular to limit aggressive overvolting especially if higher manual vids are being defined for VCCSA voltage. A nominal value of 1.100 with a LLC of regular offer solid vid support for configurations at 1600MHz (including 8 DIMM configurations) for speeds in excess of 1600 first try 1.100 vid. If stability fails to be met first consider setting a more aggressive LLC setting this (between high or extreme) these parameters should yield better results for modules up to 1866 and potentially 2133. Should stability still not be met consideration for VCCSA ranges of 1.200 to 1.300 can be consider but are not generally recommended.
VCCSA Current Capability-
This option is key an ensuring OCP trigger point is not hit when overclocking as well as heavily loading memory. This value needs to be defined dependent on the load of applications and potential stress tests. Overall a recommended % is 120% this should allow for stability under heavy memory load for frequencies exceeding 1866 and voltages higher than 1.65 it is advised to consider 130%.
