We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS, MSI, Western Digital and Corsair.

The line-up of boards includes the MSI 990FXA-GD80 we looked at recently with the AMD FX-8150. Alongside that, we've got an A75 based ASRock board using our A8-3850 along with a H67 based ASUS board using our 2600k.

As for the rest of the system, there are no changes, so let's just get into the overclocking side of things. While AMD say we can go as high as 1.515v on the CPU core, we didn't want to go near that at the moment. Instead we wanted to sit around the 1.45v mark.

Surprisingly enough, our overclock was really strong coming in at 4.73GHz. This is only 30MHz lower than what we saw on our first FX-8150 sample which was running at 1.512v.

You can see below that this was done via the help of our multiplier which was pushed to 23.5x. Combined with the 201 BCLK, we come in at 4.73GHz.


I would've loved to push the voltage up to around the 1.5v area like we did with our original FX-8150 to see if we could get higher, but after having ours die and hearing about others dieing, we're a little skeptical at the moment.

Let's get started!
