Overclocking Gigabyte GV-N56GOC-1GI graphics cards in SLI configuration?

[Mr Davo]

Hi Everyone,

I have two Gigabyte GV-N56GOC-1GI graphics card in SLI configuration, and a few questions to ask the forum community -

1). What is a safe operating temperature for these cards? Typically they run between 42 to 50 Degrees Celsius when not overclocked. However I have started to experiment with overclocking and had them sitting between 55 - 60 Degrees C.

2). GPU to Memory Bus ratio: I have divided the Memory Bus frequency by the GPU frequency (the end result being approximately 4.2), and then when overclocking have simply nominated a new GPU frequency (of say +100MHz over default) and then calculated a new memory bus frequency using the ratio. Is this a good approach to overclocking the frequency on these cards?

3). I have been using the Gigabyte Overclock Guru II software, however I am wondering if I can get away with using MSI AfterBurner with my cards?

Any help here will be much appreciated.

Kind Regards,

David

Well generally speaking around about 100 degrees is maximum temperature for a gpu, so if they always stay below 65-70 degrees you should have no problems what so ever.

The thing with overclocking gpu's is that each individual card is different. So rather than go about calculating the ratio (even though it's a pretty good idea) you just need to experiment and learn the ranges of the card, increasing both by increments to see how they preform. Usually increasing the memory clock isn't necessary, but sometimes it allows you to achieve greater clock speeds when it is increased.

Yeah it's usually better to use the software which was designed for the certain cards, but msi afterburner will just work all the same.
