Overclocking Athlon II 245 need help

[Koda]

Hi guys, I decided I want to overclock my Athlon 245 to 3.190 Ghz on an Asus m4n78 SE and a tiny stock cooler. I went to bios and increased the cpu bus speed to 220Mhz and that did it. At the moment I am stress testing it using CPU Stability Test 6.0 and I'm monitoring the temps with Everest, SIW and Speedfan. Also I'm getting voltages as high as 1.408v is that high??

The thing is I'm getting some confusing readouts from all the apps I'm using.
With everst I'm getting:
Motherboard 35 °C (95 °F)
CPU #1 / Core #1 48 °C (118 °F)
CPU #1 / Core #2 48 °C (118 °F)
MCP 64 °C (147 °F) <-- What is MCP and should it be so high?
Aux 59 °C (138 °F) <-- Same question as above.

CPU temp is constant at 48 °C under load and I'm content with it.

In SIW core temps are at 49 °C constant Under load but I also get this:

TMPIN0 60 °C (139 °F) 59 °C (138 °F) 60 °C (139 °F)
Assembly 41 °C (105 °F) 40 °C (103 °F) 41 °C (105 °F)
What the hell are these readings???

BTW this is my first overclock and I don't know if I'm doing it right. Should I be doing something differently?? Any help will be greatly appreciated.

MCP is the chipset, under the yellow heatsink:



Since it's nVidia, it's no surprise it's at 64c and it generally stays at that temperature but overclocking may rise it a bit. So it won't hurt mounting some fan in that area.

Aux - it's up to the mb makers where they put it or if that even gives correct value at all - it could be under the cpu pins (but i doubt it in your case).
It could indicate the temperature of the MCP from a different place or it could read the temperature near the voltage regulators for the cpu.

Anyway... if you're gonna up the voltage and keep it there you should pay attention to the chips above the cpu (in the picture) - they regulate the voltage sent to the cpu and if your mb looks like in the picture, the mb makers considered they'll be cooled enough by the air from the cooler. If you have a small/weak fan ... you may overheat them.

It's simple, in order to overclock safely you must keep things cool, it doesn't help that you have the Northbridge at 65*C and the CPU near 50*C and that's just idle.

First get better cooling I don't care if you have to tie a box fan to the case, cooling is critical!

It allows you to handle higher voltage.

Two what's the stock voltage for your processor? Frankly raising the voltage by .5 isn't going to kill your processor, well if you don't keep it cool that is.
Hell I took something from 1.3 to 1.5 and 1.4 to 1.8 and it ran fine. I've seen people push over 2 volts.

Some times you may have to raise the voltage on the northbridge to obtain higher clocks.

Three: Use prime95 or orthos. This allows you to stress test memory along with torturing the CPU to make sure the higher clocks are not screwing your timings.

As for everything else: they say to bump only 10-20mhz, but I always jump by 50-75 mhz to see if it boots, if it doesn't. Fail-safe boot it and bump the voltage up by .5 or lower the clock if that doesn't work.

everyone makes overclocking sound like it's complicated but it's not. Keep it cool and bump voltage when you need it and don't keep pushing it after you hit your desire clock and you won't have any problems.

Yes there is a risk but only if you do a 200% Overclock without proper cooling and the components overheat and burn-out or the chip or board couldn't handle it due to poor quality then *poof!

I would not do it...unless its not an nvidia chipset. nvidia chips are known for dying, including from heat. overclocking just makes things worse

So what you are saying is I pretty much shouldn't do any overclocking on this chipset??

You can do it, but don't expect reliability. AMD chipsets are generally better for OCing, i've got the same chip as you running at 3.5GHz, but that's with decent ram (though the timings have been retarded to allow this frequency) and the stock pipecooler with good case airflow. good case airflow and it should be okay. the board won't last long but by the time it breaks you will most likely want/get a better board anyway. try to avoid the MCP chipsets and go for the distinct ones.
