Overclocking Athlon II X4 630

post #1 of 4
Thread Starter 
Hello, I am trying to oc my cpu to at least 3.5 GHz, I've read and read guides and posts and manage to get to 3.4 Ghz with full load temps of 38~40 ºC, bus is at 243. I underclocked the ram and adjusted the timings.

Validation

I noticed something weird, in the bios the vcore is set at 1.4 V and cpu-z shows it at 1.448 V.

But my question is, what can I do to get to 3.5 Ghz?

Thanks
Angela

That is called Vdroop. Higher end mobo's generally have better VRM's and a more dynamic phase control (4+1, 8+1, 8+2) You can tell by the number of square chokes stacked around the vrm section of the mobo in between the socket and the I/O panel in the back.

Yours looks like a 4+1 set up but the mosfets are not cooled so they may be jumping so much because of the heat. .048 seems like a lot of vdroop, you could try to increase your vdd voltage to 1.4 then match the cpu voltage to it to help narrow the core fluctuation under load.

To get to 3.5 you are going to have to get your Ref Clock to 250mhz. To get there I would up the NB voltage and cpu voltage while keeping the nb, ht and memory clocks pretty low.

As a first step you need to determine the maximum ref clock your processor can handle. To do that, set your ht/nb/cpu multipliers to their lowest and keep the voltages at stock. Then start upping your fsb, first 10mhz at a time until you find unstability, then go back to the last stable speed and go up 2 mhz at a time until you find the highest speed without voltage increase. Then increase voltage and move up from there, stress testing after each boot until you find your maximum stable Reference clock. Hopefully your max RC will be well above 250, if not, 3.5 will be very difficult.

So I thought that 3.4 was stable but it wasnt, now I went back to 3.2 with stock vcore of 1.375 and still shows a higher value in the os of 1.40~1.42. I dont know if should keep trying to oc more, or leave it there.

Your can go up to 1.55 as long as your temps are good.
