I grabbed our reference AMD Radeon HD 7750 video card from the package, installed it in my testbed and thought I'd see how overclocking went. Firing up MSI Afterburner it came as no surprise that we didn't have voltage adjustment. So, heading into the Catalyst Control Center I maxed out the core clock and memory clock which was +100MHz and +400MHz QDR respectively.
3DMark 11 fired up and froze straight away. All of a sudden I found myself with something that was going to become real boring, real quickly. Of course it then clicked that just because we don't have a CrossFire connector it doesn't mean CrossFire can't be used.
Looking at the AMD website for the HD 7750 you'll find that CrossFire is of course supported on the model and I figured why not pair it up with our HIS HD 7750 we looked at and see what kind of performance we can get. It would be interesting to see what would go down with CrossFire scaling on this lower end model which carried with it no CrossFire bridge.
We're not quite sure how many people are out there wondering how the HD 7750 would go in CrossFire and up until a few hours ago we weren't either. We wonder what can this $200ish US setup do for us, though.
There's only one way to find out, but before we do that the first thing we need to do is take a closer look at the reference HD 7750 which of course doesn't come with a package since it did come from AMD directly. Once we've done that we'll take a quick look at our testbed and cover the cards we're using today before we get into the performance side of things.
