1090T overclocking on GA-890FXA-UD7

post #1 of 7
Thread Starter 
so i just got my new H70 and got it in and running can already see about 20c drop, now im new to OCing, can someone help me with the gigabyte bios please. For OCing my cpu what features do i need to turn off and possibly on, also i noticed im running my Vcore at 1.45 but my board has a feature that auto reduces the voltage to around 1.28 when not under load or something does this mean that when i set my power to manual config i should decrease my voltage to 1.28 before i start Ocing?

My advice first off would be to turn Core Boost and Cool N' Quiet off in the BIOS, as they can have unwanted effects on your settings.

Anyway, have you got your chip up to 4.0 GHz already? 1.45v-1.475v should be enough to get you there if your chip is decent.

blend is for ram,cpu i think
small is for cpu, cpu/nb i think
i could be wrong i usually use intel test burn 30 runs at maximum and run 2-4 hours of memtest for windows then if that passes i run some crysis benchmark/ heaven dx11 loops if they pass bfbc2 for hours

try 4.0 settings
I don't have a unlocked multi so i don't know what divider times what cpu clock you need
My multi is stuck at 14 so i have to enter 286x14=4004 but your multi will go above 14
turn off turbo,cool and quiet.and c1e
disable any spread spectrum anything
vcore 1.450-1.475
nb 1.2
cpu/nb 1.325
set your memory voltage and timing to stock <----worry about tweaking that later
set ht link to 2000
set cpu/nb to 2000<-- once again worry about tweaking that once 4.0 is stable

if thats stable.,.,. try running the ht link as close to 2000 as you can and the cpu/nb as high as 3000 as you can get it,may need more cpu/nb voltage but i doubt it
If you do need more cpu/nb volts use the next lvl up in the voltage spectrum and retest

For 4ghz you usually need 1.475-1.5 and dot forget CPU/NB is sometimes preferred with thuban, so if a OC is unstable, first pump th CPU/NB volt
