If you've already overclocked your cpu and ram or have been following along in our overclocking guides:
- How to Overclock - Intel Core i7, i5, i3 CPU Overclocking Guide
- Memory (RAM) Overclocking Guide - DDR3
You should know your maximum BCLK, CPU, and RAM speeds.
However, there's a good chance that you needed one BCLK to achieve your maximum cpu speed and a different BCLK to achieve your maximum ram frequency. Additionally, your maximum BCLK is probably higher than both of these values.
So what should you do? In this guide, we'll go over the best ways to simultaneously optimize your BCLK, CPU, and memory speeds, so you'll be able to get the most out of your system as a whole.
Optimizing with a Fixed CPU Multiplier
Well, if you're using a fixed multiplier (turbo boost is disabled), you should try to lower your processor multiplier, so you'll be able to achieve the same speed at the highest BCLK possible.
For example, if you were able to overclock your CPU to 3.9 GHz (with a BCLK of 195 and a multiplier of 20) and your maximum BCLK is 210, you may be able to lower your multiplier to 19 and up your BCLK to 205 to achieve about the same CPU speed (205 * 19 = 3895 MHz).
You can do the same thing with your ram, but it is a little harder because most systems only have three memory multipliers. In this case, set your ram multiplier as high as it can stably go at the BCLK you just determined above. If you lose any memory speed by decreasing the multiplier, you can usually regain most of the performance back by tightening your ram timings (which we'll go over soon).
All things being equal, it's usually better to run your system at the highest BCLK possible (even if the ram frequency suffers as mentioned above), since this usually runs everything at a higher speed. However, this may not always be the case. In order to know which way is really better, you would need to benchmark your system in both situations to show which one gives you the highest overall performance.
Optimizing with Turbo Boost
If turbo boost is enabled, you're a little more limited in what you can do here because you can't lower your CPU multiplier to achieve a higher BCLK. If you did, it would disable turbo boost.
So, in this case, I'd just recommend running your RAM at the highest multiplier you can, and then just tightening the memory timings as much as possible to yield the best possible performance.
Tightening Your Memory Timings
We have another guide that goes over how to tighten your ram timings: Tightening Your Memory (RAM) Timings.
Once you've done that, your system should be optimized to perform at its best.
