Memory clock over 2000 MHz? Here’s the trick!
Now we come to the most exciting part of the article. You want to increase the memory clock above the limit of 2000 MHz set in MSI Afterburner and are wondering why some users – especially some Chinese overclockers in 3DMark – seem to achieve higher values than you? Perhaps you have already tried other tools such as ASUS GPU Tweak, only to find that your card allows a higher memory clock, but switches to base mode and performance drops drastically (see section on boost clock problem).
I’ll show you how you can work around this limitation and achieve both a high core clock and the maximum possible memory clock in a stable manner – without any complicated workarounds or loss of performance. You will need the following tools from page one:
- MSI Afterburner
- EVGA Precision X1
Before you try this method, you should have already determined your maximum stable values for the core clock and make sure that your VRAM can handle the 2000 MHz without any problems. Only when you know these basic values can you optimize further.
Proceed step by step in the following order:
- Start both the MSI Afterburner and the EVGA Precision X1.
- Enter the already determined stable values for core and memory clock in the MSI Afterburner and apply the settings. It is important that both tools remain open during the entire process.
- Set your fan curve and other settings in the MSI Afterburner as you want to keep them later. Example settings would be: 400 MHz core clock, 2000 MHz memory clock.
- Now start a 3D application in windowed mode – this can be a 3DMark run in windowed mode or a game of your choice.
- While the 3D application is running, increase the memory clock in the EVGA Precision X1 Tool. If your card has good cooling, 3000 MHz can be achieved directly in many cases. The core clock will initially drop slightly, but the offset from the MSI Afterburner will be retained and added to the base clock frequency. This avoids the usual limitation of driver telemetry. With this method, you can use both a high core clock and the maximum possible memory clock without the card switching to base mode and the performance dropping.

After you have adjusted the memory clock in the EVGA Precision X1, you should now also readjust the core clock there accordingly. In most cases, you can set a similar offset as in the MSI Afterburner to get back to your previous stable clock rate. However, there is often a small offset in the actual clock rates, which is why it makes sense to start about 50 MHz below your original value and gradually work your way back to the maximum stable frequency.
For example, if you were able to use a stable 400 MHz in the MSI Afterburner, start with 350 MHz in the Precision X1 and slowly increase until you reach your stable limit again.
If you also want to adjust the power limit – be it an increase for maximum performance or a reduction to increase efficiency – you must now also set this in the EVGA Precision X1. The power limit adjustment in the MSI Afterburner no longer has any effect in this setup as soon as the settings are applied in the Precision X1.
Example settings in Precision X1 after the adjustment:
- Core clock: 350 MHz (increase further if necessary, up to the stable limit)
- Memory clock: 3000 MHz
- Power limit: Increase or reduce as desired
With this procedure, you can bypass the telemetry limitations and maximize both the memory clock and the core clock without the card switching to base mode or losing performance.
Congratulations, you have outsmarted Nvidia and are now smarter than some of your Youtube colleagues across the pond. With a good card, you can now go on a record hunt. Have fun with it!
