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.

HOW TO CHOOSE A GOOD VGA

You may have heard stories like this, or you've been there.
One day pack jason comes to a computer store and want to buy a VGA to his son who wants to play games. Mr. Jason asked in a computer store and ask a store to his desire. Because ignorance pack jason only know of children that have to buy a VGA at 1 mb and say at the store. then the store gave vga antecedent intention to pack jason with VGA saying that was enough for his needs. After pak amir home and try it, how disappointed he saw that the VGA can not play games on his daughter's intentions.
The story was often the case, so perhaps this article will help you choose the VGA is good and right when you shop.
Things need to ask the seller if you want to buy a VGA:
1. A large memory capacity VGA, ordinary buyers say 1GB or 512 MB (pack jason examples like buying a VGA to ask 1 GB). But it needs to be explained is not always 1 GB is better than 512 MB.Jelasnya can be read at point 4.
2. Chip in if you want, currently on the market there is a chip ATI or NVIDIA. based on our experience to work, Ati is better in the field of image and NVIDIA better in the field of video editing and more compatible to all games.
3. Ask the buyer how many bits wide VGA data is offered to you. the more bits the better because it will be faster, eg 64 bits, 128 bits, 256 bits, 512 bits.
4. Ask all memory used whether DDR2 or DDR3 or DDR DDR5 because the greater its louder. Please know of the memory does not determine speed. For example if you buy 1 GB DDR2 VGA is not better than you buy a VGA 512 MB DDR3 (usually store play it here).
5. See Heat sinks are "the bigger is better", but see also the attached memory space to get enough air or not.
6. adjust your monitor. The bigger your monitor, the greater the force that need a VGA to play the game. Examples for monitors 16 "GT240 can choose 128-bit DDR3, when the monitor is 19" to try GT 240 128 Bit DDR5, and 22 "can use 256-bit DDR3 GT250.
7. Brands do not dwell on is not always the best, based on the experience we all now follow the reference VGA quality so nearly all manufacturers of all brands have type2 sama.karena on everything from low to high. so the benchmark buyer of the option is only 1-6. 

  
We give examples of a common VGA in use and could be a reference and learning if you want to know more details. at the start of the general low to middle men who buy (VGA $ 400 we did not include)
For office or HTPC (range $ 40-50):
1. NVIDIA 210 GT Mem DDR 2 / DDR 3 64 BIT (512 MB / 1 GB) 2. NVIDIA 9400 GT Mem DDR2 64 BIT (512 MB / 1 GB) 3. ATI HD 5450 Mem DDR2 64 BIT (512 MB / 1GB)
To Game online or HTPC (range $50-80)
1. NVIDIA GT220 Mem DDR2 / DDR3 128 BIT (512 MB / 1 GB) 2. NVIDIA 9500 GT Mem DDR2 / DDR3 128 BIT (512 MB / 1 GB) 3. ATI HD 5555 Mem DDR2 128 BIT (512 MB / 1 GB) 4. NVIDIA 240 GT Mem DDR3 128 BIT (512 MB / 1 GB)
For Game Offline such as COD, Battle Field, Starcraft 2 (high RES) (range $ 90 - 120)
1. NVIDIA 240 GT BIT Mem DDR 5128 (512 MB / 1 GB) 2. NVIDIA 250 GT BIT Mem DDR 3256 (512 MB / 1 GB) 3. ATI HD 4650 BIT Mem DDR 3256 (512 MB / 1 GB) 4. ATI HD 5770 BIT Mem DDR 5128 (512 MB / 1 GB)
For a new game or the next 1-2 years (range $ 200 - 300)
1. NVIDIA 460 GT Mem DDR 5192 BIT / BIT 256 (758 MB (192 BIT) / 1 GB (256 BIT)) 2. ATI HD 5830 Mem BIT DDR5 256 (1 GB)
Similarly, info select VGA this time, hopefully to help you shop VGA and can be used to suit your needs thanks and congratulations to shop:)
