Intel Core i5-760 Review

Overclocking / Turbo Mode (CPU/Motherboard)

The i5-760 like the 750 before it includes Intels Turbo Mode technology which allows the CPU to vary its top speed depending on the workload. In an application which is using a single thread/core the CPU will increase its speed up to 3.3GHz. Mulit-threaded applications we tend to see 2.93GHz operation. Here are the results comparing 2.8GHz and 2.93GHz in Cinebench 11.5.


Earlier in the article we noted that the ECS BIOS allows us to choose between some pre-set profiles for overclocking. To test this feature we enabled the High OC profile when running with the Core i5-760. This increased the BCLK speed to 160MHz (from 133MHz) and this combined with the Turbo Multiplier of 22 gave us a CPU which ran at 3.5GHz in multi-thread scenarios.

It was a very simple process, as it should be, and even novice users should be able to use the ECS board to maximise the potential of their CPU.

Of course enthusiasts will be more interested in the potential of the board in a manual overclocking scenario. To test this we upped our voltages to a reasonably safe level for our components and began raising the BCLK (the i5-760 is not an unlocked CPU). We soon passed by 200MHz without issue, eventually hitting 210×21 (4.4GHz) with complete stability. This is an overclock of 1.6GHz from stock.

Anyone with Photoshop can claim a huge overclock though so here is our CPUz validation of this frequency for those who wish to see it. Always look for this type of link when viewing reviews to ensure you are not being misled about the potential of a component or system.


Using Cinebench to test the difference between stock speed and 4.4GHz we can see that the overclocked result is vastly superior. For those with a decent cooler, this should be achievable and with a little more time to tweak, even 4.45-4.5GHz should be achievable.
