Sapphire HD 7970 Vapor-X EZ OC Question

Hi all,

I recently purchased a Sapphire HD 7970 Vapor-X 3Gb. Saw the EZ-OC button feature of this card. I am an OC noob and here are my questions:

1a) Should I press the button to activate EZ-OC, making sure the OC function is off in CCC, and them just sit back and enjoy gaming; or

1b) Should I press the button AND change OC settings on CCC; or

1c) Not to use this EZ-OC button at all and use CCC to overclock my card by my own.

Also,

2) At what frequency should I OC my GPU and memory to (and not pushing the limit. I do want this card to last for at least 3 years just to be safe)

Finally,

3) Should I use TriXX or CCC to overclock the GPU (and memory)?


Here is the spec of my desktop:
CPU: i5-3570K
MB: Gigabyte Z77X-UD3H
GPU: Sapphire HD 7970 3Gb Vapor-X
RAM: Corsair Vengeance (2x4Gb) CML8GX3M2A1600C9
Fan: CM Hyper 212x
SSD: Samsung 840 Pro 128Gb

Thanks for helping!!!

Just use the EZ-OC button...since the memory is clocked at 6000MHz just bump it up to 6100Mhz & change the core clock to 1200MHz

So I use the EZ-OC button and then go to CCC and change the core clock to 1200MHz?

If the the EZ-OC button only lets you click it to overclock...just use the button as it's easier, if it doesn't go to CCC and change it. You either do one not both

You are probably using the Vapor-X 7970 GHz edition, because I can't find any other Vapor-X 7970 apart from the 6GB GHz.

The EZ-OC button basically activates the Powertune Dynamic Boost feature which is a preset overclock. Pressing the button will overclock your card by a pathetic 50Mhz.

You may use EZ-OC or overclock yourself, but not both at the same time. Overclocking yourself will definitely achieve greater performance boost, but will void the product warranty if it fries.

It's definitely the 3GB version (well I don't mind if it is a 6GB it's a lot more expensive lol). The button is next to the Crossfire X ports.

Also, the free version of 3Dmark11 is okay for testing the OC performance right?

3DMark is a benchmarking software, it generates a score for you to compare and see how well your computer fares at heavy 3D applications.

When you overclock, you will want to test for stability instead of performance. FurMark is designed to test just that. It is also free.

There is little point in stability testing a preset overclock. You'll only want to do it when you manually overclock it by a greater amount.
