Right, it's time to put our reasonably priced CPU to the test and also have a look at a Clarkdale processor. Here you can see the Core i3 530 processor.

The Core i5 series is compatible with P55, H55 and Q57 chipsets. For P55 motherboards be sure to have the latest BIOS / firmware installed supporting Clarkdale. Be aware of the fact though the P55 does not support the IGP -- thus you'll need a dedicated graphics card.

As you can notice we are dealing with a vanilla Intel sample here. This particular Clarkdale processor is tagged as Q3GR ES with the ES standing for engineering sample.

Here's a photo of the backside of the processor, that's LGA Socket 1156.
