Overclocking the AMD Phenom II fun!
 

To put it in easy I've been overclocking my system to find the right amount of volts, FSB Speed, and Multipliers necessary to keep a stable overclock.

I just figured I share my fun results. I say fun because of the trial and error of shutting down and rebooting many a times.

AMD Phenom II X4 940 (3.0GHz)

Stable Overclock 1 (Under a 3 hour stress test on all 4 cores at once)

3400 MHz (3.4GHz)
FSB = 200
Multiplier = 17x
CPU Voltage = 1.3750 (New Voltage Test and Passed 3-hour stress test)
FSB Voltage = 1.2000

Stable Overclock 2 (Under a 3 hour stress test on all 4 cores at once)

3500 MHz (3.5GHz)
FSB = 200
Multiplier = 17.5x (17.5 * 200 = 3500)
CPU Voltage = 1.4000
FSB Voltage = 1.2000

My next step is to increase the FSB(Front Side Bus) Speed to 210 and archive a slightly higher clock so that I don't have to clock the Multiplier and CPU voltage as high.

This is a first step, I'll post the others when I finish overclocking to 4.0GHz.

I'm running a water cooled system and the system is staying anywhere from 34C to 40C. So I'm not real worried about the heat.

Nice! Do you set the VCORE manually? How long have you run relevant stress tests, and what memory frequencies do you use?

Yes, I set the VCORE manually, it was quite a mess getting it just right.

As far as stress tests go, I did an extra 3-hour stress test on the 3.5GHz overclock after I'd done these and it lasted and went up to 47C. Which is a tad bit high.

The memory frequency is 400MHz.

Sorry for double posting, but I updated the first post with pictures of CPU-Z information.

It looks like we use the same models of RAM sticks. As for temperatures, <40ºC sounds very low. C2D/C2Q overclockers generally let their load temperatures reach 60ºC - 70ºC, and it doesn't sound likely that Phenom II can't at least get fairly close to those temperatures without resulting in a thermodynamical cataclysm. I think you can push your vcore another 0.5V without much additional risk. However, you should probably procure some 1066 MHz Corsair sticks (e.g. PC3-8500 if your motherboard can handle it) if you want to overclock it a bit more.

You both are too intelligent, and have way more money then I will ever possess.

Faggots.

By this you mean you think the Phenom II can get that high right? Well if it is, the AMD Phenom II, as far as I know, can get hotter and colder than the Intel Quad Cores can. They've tested it in -280ºC with 6.5GHz overclock. I'll try it and see how hot it can get before I start smelling smoke or at least weird stuff starts happening.

Nah, I'll get it higher, if I start worrying about temperatures, then I might do something.

-273.15°C is absolute zero. Anyway, I don't think heat will be as much of a problem as the vcore. Once/if you hit 1.5V and find your best, stable overclock, it's probably your limit unless you want to put your system under significant stress and risk.
