The automatic profiles then still have some work to do. Loading a DRAM OC profile instead then defaulted the CPU clocks back. This however defaulted the memory to a lowly 2133MHz. Voltages this time did get changed to a safe 1.35V for Vcore and 1.25V for the uncore. The overclocking profiles instead gave us something more useful – by selecting the profile for a “gamer’s 6 core profile” – this then loaded a fully manual setup to give 4.5GHz for 1-3 cores and 4.3GHz for 4-6 cores. This seemed a little silly but is better than nothing if you are a beginner: On our test system it didn’t screw with any voltages but simply chose the fastest XMP profile only this time it used the 100 strap and a 42 multiplier to give us the expected 4.2GHz. The “Level Up” functionality lets you choose a preset frequency and the bios will mess around a bit and pop back up with that frequency. If you are new to overclocking there are some settings you can use here. A 5960X on the other hand averages about 100MHz less still. 4600MHz is about average for a 5820K or 5930K and this CPU was definitely average. You can also see the “target” frequencies are shown at the top. This is because in the early days this showed a lot more stability. When you select XMP on any “high” speed kit the bios also increases the cpu strap to 125 automatically. Here we can see a few things – I like to use the XMP profile for memory first as a baseline. “Extreme Tweaker” is where you’ll spend most of your overclocking time in the BIOS: It should be noted that in these screen shots I had been attempting some memory overclocks that caused only 3/4 DIMMs to post. We’re only going to focus on the “advanced” version of the BIOS. So with all this in mind let’s take a look at the bios. A simple overclock would again mean turning up your core voltage and upping your multiplier – if you’re new there are even some predefined overclock profiles that essentially do that alongside a fairly safe and mild overclock. Things are a bit more complicated with X99 but not dramatically so. Suddenly all that mattered was a good chip, your vcore and your multiplier. Back in the “good old” X58 days overclocking was more complicated, then the 2600K arrived and simplified everything massively. Now that we’ve had a detailed look of the board and all the accessories it’s time to take a look at performance, after all that’s why we’re here! Let’s start off with the basics of overclocking on X99 then.
