So you can only adjust the voltage offsets, and not the voltages themselves.
By manually adjusting the voltage, you should be able to OC much higher.
I believe your stock voltage on your CPU is between 1.18 volts to 1.26 volts (It will vary a tiny bit as your processor comes under load. This is normal. ) Please double check me, because if i am wrong you could damage your CPU. Use CPU-Z to check on your current voltage --> http://www.cpuid.com/softwares/cpu-z.html
So I believe your be able to go up to an offset of about +1.25V before you have to worry about damaging your processor from too much voltage (typically your processor will start overheating long before you get to that voltage). I would increment the voltage +0.2 volts at a time, testing for CPU temperature after each change.
A tiny but of voltage change might make a huge jump in temperature, (epically at higher voltages) so be careful. The temperature increase is exponential. Increasing from a 0.2 to a 0.4 offset might only increase your temps by lets say 3 C hotter. Where a offset increase from 1.0 V to 1.2V might change your temps by lets say 20 C hotter.
If your memory divider is adjusted so that your RAM is still running at close to stock speeds, you don't need to over-volt your ram. If your running your RAM above stock speeds, your need a little voltage boost to get stable. How high can you go with the RAM? Well, that entirely depends on the manufacturer of the RAM. High performance RAM heat spreaders can take as much more voltage than cheap RAM with heat spreaders (usually).
Stock for DDR (1) is 2.5V, so I am assuming you have DDR RAM. 2.8 volts is the the max "guaranteed" safe voltage. So, try a offset of up to +0.3 V for the RAM. I have heard people run as high as 3.0 volts without a problem, but I would not recommend it.
Just curious, is English your second language?
Thanks for running Prime95. If the computer does not crash with Prime 95, then it will not crash wile your doing something intensive. If it does not overheat during Prime95, then nothing will overheat it. :-)Edited by crimsontears809739 - 4/4/13 at 9:36am
