BIOS Setup
My OC Gene Long duraton mantaned
Ths 󰘰eld allows you to customze Long duraton mantaned for OC Gene functon.
My OC Gene Short duraton power lmt
Ths 󰘰eld allows you to customze Short duraton power mt for OC Gene functon.
My CPU Core Voltage/ My OC Gene CPU I/O Voltage/ My OC Gene DRAM
Voltage/ My OC Gene GPU Voltage
These tems are used to spec󰘰c the voltage of CPU, Memory, GPU and chpset for
OC Gene functon.
Current CPU Core Voltage/ Current CPU I/O Core Voltage/ Current DRAM Voltage/
Current GPU Voltage
These tems show current CPU/ CPU I/O/ DRAM/ GPU voltage. Read-only.
DRAM Reference Clock
Ths tem allows you to spec󰘰c the DRAM Reference Clock for CPU. Please note the
overclockng behavor s not guaranteed.
DRAM Frequency
Ths tem allows you to adjust the DRAM frequency. Please note the overclockng
behavor s not guaranteed.
Adjusted DRAM Frequency
It shows the adjusted DRAM frequency. Read-only.
Extreme Memory Pro󰘰le (X.M.P)
Ths tem s used to enable/dsable the Intel Extreme Memory Pro󰘰le (XMP). For further
nformaton please refer to Intel’s o󰘲cal webste.
DRAM Tmng Mode
Select whether DRAM tmng s controlled by the SPD (Seral Presence Detect)
EEPROM on the DRAM module. Settng to [Auto] enables DRAM tmngs and the
followng “Advanced DRAM Con󰘰guraton” sub-menu to be determned by BIOS based
on the con󰘰guratons on the SPD. Selectng [Lnk] or [Unlnk] allows users to con󰘰gure
the DRAM tmngs for each channel and the followng related “Advanced DRAM
Con󰘰guraton” sub-menu manually.
Advanced DRAM Con󰘰guraton
Press <Enter> to enter the sub-menu.
Command Rate
Ths settng controls the DRAM command rate.
tCL
Controls CAS latency whch determnes the tmng delay (n clock cycles) of startng
a read command after recevng data.
tRCD
Determnes the tmng of the transton from RAS (row address strobe) to CAS
(column address strobe). The less clock cycles, the faster the DRAM performance.
