Hey OC forum!
I could really use some help on how to set this up, so far system is clocked to 225Mhz with a 14 multiplier, all voltages set to auto. I have an awful AMIBIOS and its a pain in the neck to get my head around. Any advise is helpful!

maximum built in OC is 10%, which is 220Mhz, I have managed 225, but after that the PC restarts on stress tests using Prime95, so is auto voltages using too much power for the PSU? I do intend to upgrade it when I can, but for now I just need to work around it.
 
i'll pull the brand for the PSU when i can, but its bad and only rated at 400w i believe. i use the stock cooler for the processor, which from what i hear can actually be quite good
 
I suggest that you overclock manually. Don't use automatic voltage.

When you raise FSB, you also increase the DDR frequency and northbridge. Drop the CPU multiplier, and find a suitable clock for the memory first, use HCI MemTest or MemTest64 to test stability, and then run Prime95 on blend. You can boost the DDR voltage to 1.6v, or 1.65v if the modules have heatspreaders.

After you find the maximum stable FSB, concentrate on the CPU.

okay

as i said, its the annoying AMIBIOS, so i'm not entirely sure on what settings are the FSB, is it just the base clock?

this is a photo i pulled from google, its not the right page, but this is the BIOS i use
 
FSB = CPU/HT Reference Clock

You'll need to disable power saving features like Cool 'n' Quiet, C1E, and Turbo boost. Disable other bugged features like GPU and PCIE overclocking.

It will be wise to disable automatic reboot in Windows. BSODs can give you indication of which component failed.
 
ah i see
my reference clock atm is 225hz, using a multiplier of 14. so do you suggest i drop the multiplier and work on the ref clock? and as for mem clock, do i drop a frequency level down, say to 533mhz, and work on the FSB clock so i don't go over 1600? i'm using 2x8gb on 1600mhz so i guess its a 800mhz base frequency for each stick?
 
When you overclock the CPU via FSB (reference clock), if affects other components as well (DDR and Northbridge).

You'll need to stress test each one separately and sometimes increase voltage when needed.

The first step is to reduce both CPU and DDR multiplier and see how high can you go with the FSB.

Afterwards, you adjust the DDR clock accordingly. DDR3-1600 runs at 800 MHz (800x2=1600). You can overclock the DDR too and get better bandwidth, but it may require some extra voltage (Memory Over Voltage) and stress testing.

After you got the FSB and DDR in order, you can start overclocking the CPU.
 
what voltage should i set for it to begin with? it should be capable at 1.4, is that safe to start? and increase ref clk until bsod, then raise voltage?
