Overclocking

Well my overclocking on the reference card from Nvidia gave me was very impressive. But I was very interested in seeing how consistent my results would be. For one, the way they select the GPU’s for a card like the GTX 760 with some of the SMX cores turned off means they are able to use GPU’s that may have failed for other cards like the GTX 770. This is great for keeping prices down but sometimes this can lead to inconsistent overclocks from card to card. Going off our previous results I was able to start with a 200 Mhz GPU offset to save a little time. Interestingly enough though, the GPU clock speed with a 200 Mhz offset was 1215 Mhz. This was noticeably lower than what we saw with the reference card. In fact, when I continued on I wasn’t able to get any more out of the card with my only other pass result being a 215 Mhz offset with the same resulting speed.

When it came to memory tests my results were a little more promising than the GPU. After a little work I was able to bump it up to a memory offset of 525Mhz without experiencing any artifacts, glitches, or crashes. Of course going to 550 resulted in a catastrophic crash of both 3DMark and my display driver, so be careful to not push it too far. This gave me an end result of 3524Mhz or 7048 Mhz. Not bad at all!

In the end it is clear that not every card is going to perform consistently when it comes to overclocking with the GTX 760’s. It will be luck of the draw even more so than normal, but even so I was still able to get respectable results with this card. They just were not as impressive as with our reference card.
