Review: Overclocking NVIDIA GeForce GTX 590

A few months ago, NVIDIA released the latest variant of the GTX 500 series graphics cards they are NVIDIA GTX 590. NVIDIA GTX 590 is a dual-GPU graphics card that uses two chips GF110. GF110 chip is the same as used on the NVIDIA GTX 580.
The lowest price range NVIDIA GTX 590 is $ 699. This price is quite high. The high price makes it only a handful of gamers / users who can enjoy the NVIDIA GTX 590. Moreover, high-performance system needs to issue a full performance from the NVIDIA GTX 590. Such systems have a price is not cheap. However, the price paid for the NVIDIA GTX 590 quite commensurate with performance and features that you'll get.
Capitalize GF110 two chips, a NVIDIA GTX 590's performance in the standard state is already quite high. However, NVIDIA GTX 590 still have a hidden force which can still be issued. This time, we will release the hidden power with overclocking. Intrigued by NVIDIA GTX 590 performance improvement after the overclock? Consider the results of our overclocking experiments below. 

NVIDIA GTX 590 

Specification 



Two chips GF110 on NVIDIA GTX 590 has the same specifications as the specifications on the NVIDIA GTX 580 GF110. However, specifications on the NVIDIA GTX 590 clocked lower than the specifications of the NVIDIA GTX 580 clock. Supposed to raise the clock specification NVIDIA GTX 590, NVIDIA GTX 590's performance is capable of approaching or matching the performance of two NVIDIA GTX 580 in SLI mode. However, if the clock is as easy as it reaches the specifications of NVIDIA GTX 580? 

Overclocking 




After seeing and reading some of the events "death" NVIDIA GTX 590 when the overclock, we decided to do the overclocking NVIDIA GTX 590 securely to prevent the NVIDIA GTX 590 we meet the same fate. To overclock the NVIDIA GTX 590, we used the MSI Afterburner tool. In addition, we also replaced the 800 Watt power supply us with a 1050 Watt power supply to prevent power shortages due to increased power consumption due to overclocking.
For the first experiment, we managed to raise the NVIDIA GTX 590 core clock to 661 MHz. Core clock is classified as (fairly) safe because it can be achieved without the need to raise GPU voltage. Meanwhile, we set the fan speed at maximum speed (95%). 

As for the second experiment, we raised the voltage to 0975 (default 0938) and a 688 MHz core clock. We also set the fan speed at maximum speed (95%). 

Filled with curiosity, we finally went to overclock the NVIDIA GTX 590 to a higher level again. With voltage 1013 V, we managed to achieve 742 MHz clock speed and memory clock of 3600 MHz.
