What is SRBMiner-MULTI and can it mine Monero?
SRBMiner-MULTI is a standalone mining program that supports several cryptocurrencies and mining methods. Yes, you can use it to mine Monero (XMR) with your computer’s processor, provided your version supports Monero’s RandomX mining method.
What SRBMiner-MULTI does
Mining software makes your hardware perform calculations that help secure a cryptocurrency network. In return, you may earn a share of the mining rewards.
The “MULTI” in SRBMiner-MULTI means it supports multiple mining algorithms. An algorithm is the set of calculation rules a cryptocurrency uses for mining.
The program supports CPU and GPU mining, though hardware support depends on the algorithm and software version:
- Your CPU is your computer’s main processor.
- Your GPU is its graphics processor, usually used for games and other visual work.
SRBMiner-MULTI runs as a separate application on supported Windows and Linux systems. It is not a browser extension or something you run inside a web page.
How it mines Monero
Monero uses RandomX, a mining algorithm designed to favor ordinary computer processors. It replaced Monero’s earlier CryptoNight-based algorithms on November 30, 2019.
In SRBMiner-MULTI, the Monero-compatible algorithm is commonly identified as randomx. Check the documentation included with your release before copying a setup command, since supported options can change.
Although SRBMiner-MULTI supports graphics cards for various algorithms, that does not make graphics cards a good choice for Monero. For XMR, focus on its CPU mining support.
RandomX also needs memory. Its fast mode uses a dataset of about 2,080 MB, plus additional working memory. For efficient mining, you generally want about 2 MB of L3 cache per mining thread. L3 cache is fast memory inside your processor; a thread is one stream of work. Using every available thread is not always the fastest setting.
What you need to start
For a typical pool-mining setup, you need:
- A Monero wallet address where you can receive payouts.
- A mining pool, which combines many miners’ work and shares rewards.
- The pool’s server address and connection settings.
- A compatible SRBMiner-MULTI release configured for RandomX.
Your miner needs your public receiving address—not your wallet’s recovery phrase or private keys. Never enter those secrets into mining software or a pool website.
Download only from the project’s official distribution channels. Fake miner downloads are a common way to spread malware. Security software may flag legitimate miners, but you should not assume every warning is harmless.
Mine only on devices you own or have explicit permission to use.
How it compares with XMRig
XMRig is another standalone miner commonly used for Monero. A key difference is that XMRig is open source, meaning its source code is publicly available for inspection. SRBMiner-MULTI is distributed as closed-source software.
Neither name alone tells you which will perform better on your processor. Compare them using the same pool, thread count, and power settings. Check each release’s developer fee or donation settings, too.
Watch electricity use, heat, and noise—not just hashrate, the number of mining calculations completed each second. Check a live profitability calculator rather than expecting a fixed daily income.
The bottom line
SRBMiner-MULTI can mine Monero through its RandomX CPU support. It is an alternative to XMRig, not a browser miner, and the better choice for you depends on measured performance, fees, and how comfortable you are using closed-source software.
