Overclock Asus M3A78-EM with Athlon II x2 250

Certainly a great change .Not a bad result, but does not indicate the voltages of the plate. Put the PCIe to 101 or 102, normally lets you upload something else. Disable the C & Q to try. 

With respect to the voltages, higher values will certainly be reading the wrong, to me sometimes I marked 10V on the 12V channel, which is impossible. 

If you do not play not worth climbing the chart. ill also say that in 3300 I have a review board to rise from 700 to 800 without touching anything and without seeking the limit. The 3200 can do just what 

I have seen several sites that say that this says it is not good to give much VCore, besides which apparently does not rise much further by the fact of giving more VCore, but I wonder if you can climb a little higher HTT giving a dot over the VCore voltage or NB, or chipset, or good with any parameter that escape ... NB Frequency I've seen in several places that are recommended not to exceed, and the HT Link a little below the stock 2000MHz to 1920MHz, but dont know whether it is worth raising the multiplier at x9 instead of x8 and is at 2160MHz, although performance is the same or better leave 2000MHz below what I think is desirable.

I tried with the 101Mhz PCI-e and I managed a good time with prime95 stable at 3750MHz (HTT to 250MHz), but having to turn up the VCore 0100 mV and 0050 mV NB voltage and temperature also the up about 4-5 º C rather than the configure and the difference in performance just a bit better with Super PI eg so almost prefer to leave it as is without touching voltages and some better temps too. 

Well, the truth is that I use to go with more than enough RAM to 3.6GHz and 960MHz, I prefer not to push things from the limit and not have touch the voltages and lower temps, which eventually will provide more life to my machine

Sapphire Radeon HD 5870 Vapor-x overclocking

Sapphire Radeon HD 5870 Vapor-x seems nice card for gaming for overclocking this card what is stress that it can handle ? how much noise it use to obtain ? is that already overclocked ? any one can tell me ?

It seems obvious technical characteristics, the proposed Sapphire, thanks to the heatsink more efficiently than the reference solution, is delivered with an operating frequency higher than the standard ones the GPU is set at 870 MHz, 850MHz compared to the canons, while memories have been brought to 5GHz, instead of 4.8 GHz In order to maintain operational stability during any kind of use, Sapphire has chosen to go even to alter the Vcore voltage, from 1.15V to 1.162V. The impact, at least in theory, you should have on consumers in this case higher, and the heat, cooling system technology Vapor chamber is a clear advantage for the proposed Sapphire

you have to choose it for overclock therwise restricted by control panel driver while MSI Afterburner can be used for the management of schemes rotation of the fan and the voltage v-core. The presence of a vapor chamber cooling technology would eliminate at least in part, the problems of excess heat, to overcome in order to track these kinds of problems during in overclocking the rotation of the fan is set manually 100%.

The ability to set even the operating frequencies directly from MSI Afterburner is not functioning usable in the case of Sapphire Radeon HD 5870 Vapor-x as often happens with the arrival of new market models is necessary to wait for a special software release to succeed to have full support. The software used in this case, the above you can see the graphical interface so best known RivaTuner.

The card is to be stable using the core voltage higher than the standard version, the GPU is increased smoothly at a frequency of 950MHz while the memory can increased up to 5.100MHz. The increase in performance, in this case is sensitive and certainly more tangible than that charged by default on Sapphire. To achieve the frequency of 1GHz was not necessary to set the voltage to 1.2V vcore, memories have proven to create major problems if you wear more than 5.100MHz, so left intact this value. Above this threshold, despite various combination of voltage and frequency, the card has proved unstable. For Sapphire Radeon HD 5870 Vapor-x level of overclocking is very good, leaving the standard voltage settings, and can reach very easily and without too many problems, the frequency of 950MHz, an attractive level, and allows you to enjoy a significant performance increase
