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
