How to overclock GPU for KAS, ALPH, IRON, RXD?
There is no "the best" way to overclock a graphics card, as it depends on individual preferences. Some prefer achieving the maximum hashrate, while others want to reduce electricity costs.
We will provide you with some basic overclocking guidelines so you can find the optimal values for your specific mining scenario.
We will focus on overclocking techniques for Nvidia and AMD GPUs, specifically for the following algorithms:
- KASPA kHeavyHash (KAS)
- Alephium Blake3 (ALPH)
- Iron Fish Blake3 (IRON)
- Radiant Sha512256D (RXD)
How to Overclock Your Graphics Card
- Miners' settings: Service commands allow you to control the miner. You can use them both in the Kryptex PRO or other standalone miners.
- MSI Afterburner: This is a universal app that you can use to overclock both Nvidia and AMD graphics cards. You can adjust the the core and memory frequencies, fan speed, and power consumption.
- Native utilities: Graphics card manufacturers often provide their overclocking utilities. For instance, AMD GPUs have a built-in overclocking tool that gets installed along with the drivers.
Be careful using overclocking commands, as different miners have their commands.
The miner.download website provides detailed information on commands and scenarios for their use.
If you want to overclock a graphics card for the KAS, ALPH, IRON, or RXD algorithms, follow these basic rules:
- Reduce the GPU memory frequency as much as possible, as these algorithms don't use the memory.
- Adjust the core frequencies and power consumption to achieve the optimal hashrate and power consumption.
- Set the fan speed according to your preferences.
Let's take overclocking the RTX 3070 as an example. You can use the same method to overclock your GPUs, or you can find detailed settings for different GPUs in our Overclocking Database.
For KAS, ALPH, IRON, and RXD algorithms, reducing the memory clock to the minimum value will lower the temperature and GPU power consumption since these algorithms don't use memory.
- In MSI Afterburner, set the Memory Clock value to the minimum of
- In the miner settings (lolminer as an example), fix the memory frequency at
810Megahertz using the command
KAS, ALPH, IRON, and RXD algorithms use the core, which means that the higher the core frequency, the higher the hashrate, but the power consumption will also increase. RTX 3000 Series best clocks will be
- In MSI Afterburner, switch to the Core Offset step.
- In the miner settings (lolminer as an example), fix the core frequency at
1470Megahertz using the command
Increasing the core frequency offset will allow the GPU to raise the frequency without raising the consumption. However, be careful not to go too high! We recomend
- In MSI Afterburner, increase Core Clock by
- In the miner settings (lolminer as an example), set the core offset to
250Megahertz using the command
Limiting the GPU's total consumption will increase the mining efficiency.
- In MSI Afterburner, reduce the Power Limit value until the hashrate starts to drop significantly or until you reach the desired value for the GPU consumption. In our case, set the value to
- In the miner settings (lolminer as an example), set the maximum consumption threshold in watts to
Adjusting the fan speed according to your preferences:
- In MSI Afterburner, set the Fan Speed to
- In the miner settings (lolminer as an example), use the command
Tests and Results
You can overclock your GPU for maximum power savings or maximum hashrate.
Here are two options:
- For maximum hashrate: 615 mh/s and 100 watts consumption:
--coff 210 --cclk 1740 --mclk 810 --pl 200 --fan 50.
- For maximum savings: 460 mh/s at 48 watt consumption:
--coff 300 --cclk 1305 --mclk 810 --pl 150 --fan 50.
Remember that overclocking differs for each graphics card; even the same graphics cards can be overclocked differently. Therefore, you should independently select overclocking settings for each card and monitor stability. No one can overclock a graphics card better than you!
