ASRock N68-GS CPU voltage increase - Is it possible?

post #1 of 9
Thread Starter 
SPECS:
CPU: AMD Athlon II X2 240 @3.35GHz (stock: 2.80GHz) It is the only important thing for this thread

So I'm in this overclocking stuff. I've read a few guide how to overclock recently, but if you want to see, here is my overclocking 'story" (Not including GPU, that is a different stuff)
*STORY STARTS
*
Once i've seen that my CPU usage is in the sky, and my FPS in game was low. So I've found that this motherboard supports the ASRock OC Tuner, Ive downloaded it. People said that overclock with BIOS, or don't overclock, but I've tired it. That was good, but it led to a lot of system crashes due to the method it uses. So I've tried the BIOS method, first that was a little bit confusing, and led to a lot of system crashed too, I only knew a few things about it. Then, I've looked up a guide how to do it properly, and now I'm here.
*STORY ENDS*
Now, I'm here with this situation: I've reached the max clock speed with the stock voltage (3.35GHz @ 1.384V), and I'm a little bit scared about increasing the voltage. I've read a post, what lists the motheboards what can handle overclock. My can handle it, but it's not on the list. I want to overclock it to the limits, but I wasn't able to find anything about the voltage increase for this motherboard. Do you have any experiences with this motherboard?

voltage increase has almost nothing to do with the motherboard.
The CPU determines how much voltage it can take.

Most AMD chips of that generation can do like 1.4 volts if you have good cooling.
But only under good cooling.
My phenom II ran at 1.5 volts, but I had that under water cooling.

Honestly you are being gimped most by the age of the platform, and the lack of CPU cores.
Your best upgrade would be to picked up a quad core or even a six core for your machine.

your board supports up to a phenom II 945 or a 1055t.

So i can increase the voltage to about 1.4V. The good cooling is... a stock in a bigger version, thermal compound is missing. The load temp is about 55 °C with the current clocks. How much will it increase? About 5-10 °C?

Now i've tried it, but it's not increasing the voltage, I think. I increase the voltage from 1.375 to 1.400, and the clock from 240 to 250. Reboot, not posting. It did the same thing without the voltage increase. Maybe it can't be overvoltaged?

It's probably something else that's causing it to not post. Are you keeping your RAM and CPU-NB below stock speeds to be sure neither of them are unstable? Could also be the the north bridge needs a little voltage increase to be able to run 250FSB. I would not go much higher than 1.20V on the north bridge unless it's required and you have good cooling on it.

I keep them near the stock speed, but the BIOS says that the max voltage is sitll 1.375, but the CPU goes above that. I can set the max voltage (in theory) but it does nothing, still 1.375V. The RAM is a little bit different story. I have to overclcok on modul, and underclock the other to get any signal. But they go on their way, due to the different base clocks.

I was looking around in CPU-Z, and found this:

CPU Name AMD Athlon(tm) II X2 240 Processor
Threading 1 CPU - 2 Core - 2 Thread
Frequency 9276.03 MHz (14 * 662.57 MHz) - Uncore: 6625.7 MHz
Multiplier Current: 14 / Min: 4 / Max: 14
Architecture Regor / DA-C3 Step (45 nm)
Cpuid / Ext. F.6.3 / 10.6
IA Extensions MMX(+), 3DNow!(+), SSE, SSE2, SSE3, SSE4A, x86-64, AMD-V
Caches L1D : 64 KB / L2 : 1024 KB
Caches Assoc. L1D : 2-way / L2 : 16-way
TDP / Vcore 59.4 Watts / 1.424 Volts
Type Retail (Original Frequency : 2800 MHz)

HOW? 9276MHz. Almost 4x of the original clock. But how? Is 1.424V enough? So it emans that I could even go over 4GHz with a small voltage increase? (Maybe I'm able to increase the voltage, but only with a BIOS unlock :/)

CPUz is reading it wrong or your motherboard is giving off false readings.

It isn't from my system and the motherboard is working correctly. But sadly the voltage increase can't be applied for some reason.
