hy
i m new in oc, i would overc. my amd athlon ii x4 620 2,6GHZ to 2,8GHZ
I have asus m4a78-em motherboard,2GB DDR2 800mhz 555-15
with these values is will good the OC?

cpu oc: manual
-CPU over clocking>>220
-PCIE Overclocking>>100

-Processor Freqency Multiply. x4.0 1300, x5.0 etc. until x11.0 2200MHZ wich i must choose?
-CPU/NB freq.t >>>10.00x
-CPU over voltage.t >>>normal ?
-VDD NB-t >>>normal ?
-Loadline Calibration >>>0%

-HT Link Freq-t >>>>2000Mhz
-Link Width: >>>auto, 8 bit ,16 bit wich?


Video on my bios:


I cant set manual the cpu Voltage, (i maked bios update but not resolved,same can check)

thank you

you have to change the voltage on the CPU VID and
the NB VID for it to stick.. remember the memory
controller(northbridge) is on the chip its self so runs
at the same voltage as the cpu.. thus they must be at
the exact save voltage..

But i cant change manual, set one voltage.....i can check these:
-auto
-normal
- + 0,5 vn
- + 1,0 vn
etc.

Yep you can use +0.5v. If your default 1.4 + 0.5v semm too high , that need drop cpu vid

You mean 0.05v or 50mV...I have that board and it only give you the voltages option of 50mV, 100mV, and 150mV....or 0.05v, 0.10v, and 0.15v...

Hy
I dont want to give more voltage.....beacuase i want use the orginal cpu cooler(what was in the cpu box when i buy,this is simple cpu cooler.)

When i choose the NORMAL in cpu over voltage option this will good?
(beacuase i hear...the when i set in overclocking the cpu voltage is auto....that can the m.board give too much voltage give for cpu..............with NORMAL can be same?)




With these settings will good?


CPU over clocking >220
-PCI OC >100

Processor Freq. Multi. >13
-CPU/NB freq.t >10.00x
-CPU over voltaget>normalra
-VDD NB > normalra
-Loadline Calibration>0%
-HT Link Freq-t tedd >2200
