Help with GIGABYTE GTX 560?

[malikelsan]

Hi guys, i recently got a GIGABYTE GTX 560 card want to over cLock its currently running at 830Mhz and want to over clock to 900Mhz do i need special cooling? like liquid cooling ? or wil i be fine (im new to OverClocking)

Thanks

Welcome to the forum.

You didn't include any hardware information, but it looks like you have the Gigabyte GTX 560 OC model.
I did a quick web search using: gigabyte gtx 560 review and looked at two reviews.
One review overclocked the gpu from 830MHz to 920MHz and the second site's overclock was 910MHz.
Your card might overclock a little higher or a little lower than their results.

You shouldn't need any special gpu cooling, but if your ambient temperatures are higher than ~ 25^o(C) your card might run too hot.
If your computer case has good cooling, this will help keep your overclocked card at reasonable temperatures.

It looks like you can't increase the gpu core voltage, but you should be OK with ~ 900MHz gpu speeds.
Read some reviews for your video card model to see what the typical limit is for overclocking your video card's memory.

We can best help you after you create a detailed hardware list in the System Specs
portion of your forum profile at the bottom of the profile page or in your forum signature.
Be sure to include brand names and model numbers.
When you are done editing or creating your hardware list, save the settings.

Hi,

I also have the GTX560 OC, and I have been experimenting with overclocking it using MSI Afterburner (which works brilliantly with my Gigabyte cards). I have overclocked my card to 872MHz and it has run stable at reasonable temperatures between 65 - 75 Degrees Celsius. I have also run the card at 912MHz, however I found that the card was getting a little too hot. To get reliable operation at these higher clock speeds I needed to adjust the Voltage on the Core (which Afterburner lets you do as well). With specific regard to cooling I personally don't use any special equipment.

Thanks

Thanks for your feedback.

The older GTX560 OC reviews that I read said MSI Afterburner and Gigabyte's Easy Boost didn't allow for voltage adjustments.

With my MSI N460GTX Hawk single and SLI overclocking I was able to increase gpu and memory voltages, but as you pointed out heat gets to be an issue and at some point you'll need to increase voltages (and heat and fan noise) a lot more just to get a really small gain in performance.

Re: Help with GIGABYTE GTX 560?

Absolutely agree on the small gain, at the higher end. I run my Core Clock at 872MHz (default is 830MHz), and whilst it does run (relatively) stable at 912MHz I am seeing a very marginal improvement in frame rate (1 or two frames) for a large increase in heat output ~ typically an increase of 5-10 Degrees C for card one, and 10-15 Degrees C for card two. With relation to frequency I saw no real gains by increasing the Memory Clock, so I simply leave this at default. Finally I also lowered my Core Voltage marginally from the default, and the card runs fine!

As a side note: when using 2 way SLI one card always runs hotter than the other - in my system - due to the fact that one card vents it heat directly into the back of the other card! Originally I had thought that my second card (purchased recently of eBay) was a dud, as it was running considerably hotter than my original card, however after swapping the cards around I came to realize that the issue is simply one of ventilation.
