Introduction
First, a disclaimer: I have never overclocked anything in real life and don't really have any desire to. Everything in this guide is base on my experimentation and observation within the game only. That being said, it's my understanding that overclocking in this game isn't that much different than actual overclocking—a little simplified and a lot less volatile—but similar nonetheless.

You have two basic actions when overclocking in this game: increase the speed of the component (RAM, CPU, or GPU) and give it the extra power (voltage) it needs. Only one of these actions is catastrophic if taken too far, at least for now. Giving RAM or a CPU too much power will cause it to break. Setting RAM voltages at 1.85 or higher runs a real chance of breaking it, and the breakage chance at a voltage of 1.90 is nearly 100%. Similarly CPUs start breaking consistently at voltages of 1.75 or higher. The program for overclocking GPUs, on the other hand, doesn't appear to allow voltages high enough to cause failure—yet.

So for now, safe initial voltage settings are:
  • RAM - 1.80v
  • CPU - 1.70v
  • GPU - Full
How high a component can have its voltage raised before failure is randomized in the game. This is probably part of how 3DMark scores of 25,000+ have been attained and posted in the forum. People get part after part, testing the limits of each until one is found that exceeds the limits of those tested before it.
RAM (Available at Level 1)
All motherboards appear to be capable of overclocking RAM, but they all have a maximum RAM overclock MHz setting (See the Motherboard chart in the CPU section below). All RAM appears to be overclockable. Here are the steps:
  • Make sure the RAM you want to overclock is installed on the motherboard.
  • Go to the monitor and start the PC (P) holding either F2 or Del to access the BIOS.
  • On the BIOS screen, look for RAM OC and click on it.
  • Here you can increase the RAM Speed and RAM Voltage. Increase RAM Speed a couple of ticks and increase RAM Voltage to around 1.80.
  • When you're done setting Speed and Voltage, find and click on Settings, click “Apply changes and restart”, and confirm by clicking Yes.
  • When the PC boots to the operating system, install and open either 3DMark or OCCT (if you have it). Run whichever testing program you are using. You won't need to run the testing program through a full cycle. If it runs fine for 10 seconds, you are not going to get a blue screen error—at least not because of the RAM. If you do get a blue screen error, reduce the RAM Speed setting in the BIOS. If not, increase the RAM Speed and test until you do get a blue screen error. Then back the RAM Speed down one notch.
When you've reached the highest MHz without a blue screen error, you are done overclocking your RAM. The higher MHz coming from the RAM will now boost your CPU score a little in 3DMark.

Here are some (hopefully helpful) settings that consistently worked for me in my testing while developing this guide:

CPU (Available at Level 6)
Not all motherboards or CPUs support overclocking (See the tables at the end of this section). Here are the basic steps for overclocking CPUs:
  • It's a good idea to get a base 3DMark CPU score before you start overclocking.
  • Make sure the CPU has thermal paste and a cooler installed. Usually, the better the cooler is, the higher you will be able to overclock the CPU. Adding high Air Flow case fans to the PC should also help.
  • Go to the monitor and start the PC (P) holding either F2 or Del to access the BIOS.
  • On the BIOS screen, look for CPU OC and click on it.
  • Here you can increase the Base Clock, Ratio, and [CPU] Voltage.
  • Note the starting CPU Speed in MHz; this is what your actions will be increasing. Increase the Ratio 5 or 6 ticks and increase Voltage to around 1.70. You can increase Base Clock too if you like, but this will also change RAM speed under RAM OC. If you do this, you may need to increase the RAM Voltage to compensate, making sure not to go so high as to break the RAM (1.80v is usually safe for RAM). I'd advise changing only one speed setting at a time, either Ratio or Base Clock, and testing each time. That will make it easier to track down problems.
  • When you're done setting Speed and Voltage, find and click on Settings, click “Apply changes and restart”, and confirm by clicking Yes.
  • When the PC boots to the operating system, install and run OCCT. Note the rows labeled CPU Temp and CPU Throttled. Keeping your eye on the Max column for these two, click the On button to start the program testing. If the Max Temp rises to the point where "CPU Throttled" goes to Yes (usually from 95 to 100 degrees) or if you get a Blue Screen error, reduce whichever Speed setting you changed in the BIOS. If not, increase the Speed and test until you do get CPU Throttle or a Blue Screen error. Then back the Speed down one notch.
  • Install and run 3DMark. If your CPU score is really low (usually 3-digit score when throttled) or if you get a blue screen error, then back the Speed down one more notch. Run 3DMark again.
You are done overclocking your CPU. Your 3DMark CPU score should be higher than when you first started.

GPU (Available at Level 13)
All GPUs in the game can be overclocked to some extent, and there is currently no way to break a GPU overclocking it. You will need to buy both the OCCT and GPU Tuner programs if you haven't already.
  • It's a good idea to get a base 3DMark GPU score and to note the size of your power supply before you start overclocking.
  • Install the GPU(s) you wish to overclock onto the motherboard.
  • Start the PC (P) to the operating system. No need to open the BIOS for this.
  • Install and run both the OCCT and GPU Tuner programs. Arrange them so that both are fully visible.
  • On the OCCT program, pick Test Type: Infinite and click the On button to start continuous testing. Wait until the Power Draw has stopped rising.
  • Since there is no way currently to break a GPU with too much voltage, slide the Core Voltage on the GPU Tuner program all the way to the right. Slide the Core Clock to the right to about halfway between where it starts and the far end (red covering about 3/4 of the slider bar).
  • Hover your mouse over the Apply button of the GPU Tuner program. While watching the GPU Temp and Power Draw displays on the OCCT Program, click the Apply button on the GPU Tuner program. Both GPU Temp and Power Draw should go up.
  • You are looking to get the initial GPU Temp around 94 degrees and keep Power Draw below your power supply limit. If you are well below both of these, slide the Memory Clock to the right and hit apply.
  • Once you've reached around 94 degrees and assuming your Power Draw is still well within limits, start creeping both Core Clock and Memory Clock to the right, hitting apply each time you move one. You can use the + at the end of the sliders for fine control. At some point, your PC will get a blue screen error.
  • Restart the PC and back down the last setting you changed.
  • Run the 3DMark program. If you get a blue screen error again, back the settings down a little more and try again.
Once the PC passes 3DMark, you're done. Your score should be higher than what you started with.

As with CPU overclocking, you will get better results here if you install high Air Flow case fans on the PC.
Advanced Overclocking
My guide is meant to be a very basic overclocking guide to get you started and to maybe save you some money in your playthrough of career mode. If you'd like to push the limits of the game and find the highest 3DMark score possible in the game, you need to check out Turbo's Guide to Binning and Overclocking:

Ill say this, if ur cpu and gpu arent smoking, the you haven't pushed the overclock hard enough. I recommend 6.9 volts for the cpu and gpu just full send.

Memory clock seems to do nothing in my testing. So underclock the gpu memory as much as you can, then increase the core clock as far as you can.
Troughy Dec 30, 2020 @ 2:56am 
Does it matter for higher GPU score if I have the Core clock or the Memory clock set higher?
