XMRig vs. SRBMiner for Monero on RandomX: Which is More Profitable and How to Set It Up on Windows

We compare XMRig and SRBMiner for Monero mining on RandomX : hashrate, stability, features, fees, Windows settings, huge pages, and MSR. We also provide practical batch files, pool selection, and income-per-watt calculations.

⚡️ A scene from the life of a miner

The computer hums like an old refrigerator. The Task Manager displays a smooth loading screen, and the console displays neat “accepted” lines. And here’s where things get interesting: two systems with the same CPU can produce different results. Not because of “magic,” but because one miner can handle Large Pages and MSR tuning, while the other can’t. And you’re not losing just a few percent. Sometimes, you’re losing half your annual salary. Okay, I’m exaggerating… but it’s still unpleasant.

🎯 What is your real goal?

If you translate your request into human language (without the marketing fluff), the goal is this:

Achieve maximum profitability with adequate support for the Monero network —that is, not just “more hashes,” but also stable operation, fair shares, clear diagnostics, a normal pool, and less downtime .

And yes, you’re thinking correctly: performance + functionality is like “engine + transmission.” One without the other sometimes looks nice, but performs poorly.

🕳️ Blind spots that are often forgotten (and then criticized)

Here’s what even experienced guys usually don’t take into account until they get burned:

Power consumption is measured “by eye .” CPU Package Power isn’t the whole system. You need a power meter on the outlet (or at least a smart PDU). Otherwise, “income/watt” is just a gimmick.
RAM and its settings . RandomX loves memory and latency. Sometimes proper XMP/timings can yield the effect you’re trying to squeeze out with “magic flags.”
Large Pages / Huge Pages : Without them, you’re literally sacrificing speed. The XMRig documentation clearly states that huge pages typically provide a 20–30% boost, while on RandomX the boost can reach up to 50% .
MSR mod . In XMRig, the wrmsr(MSR mod) parameter can provide up to a 15% speedup, depending on the system.
Pools and centralization . The pursuit of the “biggest pool” sometimes undermines decentralization (and the overall vision of Monero). There’s also the risk that a pool will become too dominant.
Security hygiene . Miners often trigger false alarms from antivirus software, and people disable protection “for a moment”… and hello, a rogue miner in startup.

🧩 RandomX without fog

RandomX was designed to prevent ASIC farms from “consuming” the network , while keeping mining accessible on regular CPUs. This is one of the reasons why Monero maintains its mining popularity and is valued by private miners.

This leads to an important conclusion:
the CPU is the main player . A GPU running RandomX is possible, but it usually loses out in terms of efficiency (and sometimes even common sense). Still, you asked to consider both options—we will.

🛠️ XMRig — RandomX’s “Swiss Army Knife” 🔧

XMRig is a high-performance, open-source, cross-platform CPU/GPU miner, complete with a benchmark, proxy, and configuration wizard.
The current version at the time of review was 6.25.0 (Windows builds available).

XMRig’s strengths:

Flexible JSON configuration and convenient settings structure (no need to keep everything in one batch file);
Rich documentation: huge pages, RandomX optimization, CPU backend parameters—everything is explained;
stability and predictability (in a good sense, “boring,” which is a compliment).

Where it can be annoying:

Some optimizations require care (Large Pages, rights, sometimes running as administrator);
If you’re looking for an all-in-one mining rig with tons of algorithms and features, SRBMiner is often a more fun option.

🧰 SRBMiner — a “combine” with character 🧪

SRBMiner-MULTI is marketed as a miner capable of mining up to four algorithms/coins simultaneously and supporting CPU and GPU (AMD/NVIDIA/INTEL) on Windows and Linux.
The releases indicate that the project is still active; for example, the release branch includes 3.0.7 .

Pros of SRBMiner (especially if you like “hybrid”):

a wide range of algorithms/modes, multi-mining as a concept;
On some configurations, people report good results on Ryzen (depending on the bundle, drivers, and settings—yes, this is a case where “you need to check”);
An interesting feature for those who play with hardware: SRBMiner has parameters for controlling frequencies and power limits on NVIDIA via the command line ( --gpu-cclock, --gpu-mclock, --gpu-plimit).

Cons/nuances:

This is closed software (unlike XMRig), which is important to some people;
The dev fee for RandomX is often listed as around 0.85% (check for your version/algorithm, the numbers may change).

📊 Profitability and Revenue per Watt 💡 (How to Calculate to Avoid Miscalculations)

The most common mistake is comparing hashrate in a vacuum. For money, this pair is more important:

H/s per watt and uptime without any fuss .

Mini-formula (without philosophy)

You take the average hashrate per hour (not per minute).
Use a wattmeter to measure the power consumption from the socket .
Do you think:

Efficiency = Hashrate (H/s) / Power (W)

Example (purely illustration):
If the system produces 20,000 H/s at 120 W , then
20,000 / 120 = 166.67 H/s per watt .

Next, you plug this into a profitability calculator (CryptoCompare and similar tools) — Monero guides directly advise first deciding on profitability based on your rates.

Why Huge Pages Are “Almost Free”

We enabled Large Pages and saw a performance boost that’s sometimes unachievable with overclocking without generating excess heat. For RandomX, the boost can reach up to 50% if everything is configured correctly.

Why MSR mod isn’t magic, it’s customization

In XMRig, the MSR mod ( wrmsr) can provide up to 15% speedup, but requires care and understanding of what you are doing.

Setting up XMRig on Windows without unnecessary mysticism 🧷

The official Monero guide for the XMRig pool on Windows is simple and straightforward: download the release archive, unzip it, and configure it.

Pre-launch checklist

Unzip XMRig into a folder without Cyrillic letters and spaces (yes, it’s trivial, but it saves your nerves).
Add the folder to Defender exclusions (carefully and consciously).
Enable Large Pages (Huge Pages). This is critical for RandomX.

An example of a batch file for a pool (minimalist, but functional)

@echo off
cd /d C:\miners\xmrig
xmrig.exe -a rx/0 -o POOL:PORT -u YOUR_WALLET.RIG -p x --tls
pause

What needs to be tweaked more “like an adult”

--threads/ auto-tuning of threads (sometimes less threads = higher efficiency, unexpectedly, yeah).
huge-pagesmust be 100% in the log – otherwise you are just heating the room.
wrmsr(MSR mod) – if you understand what you’re doing and are ready to test.

🧷 Setting up SRBMiner on Windows for RandomX 🧰

SRBMiner is traditionally loved for its all-in-one functionality and the ability to tweak many parameters directly from the command line. It’s also loved for its multi-algorithm support.

Example of a batch file for RandomX

@echo off
cd /d C:\miners\srbminer
SRBMiner-MULTI.exe --algorithm randomx --pool POOL:PORT --wallet YOUR_WALLET.RIG --password x
pause

About the GPU branch (if you really want to)

SRBMiner can set frequencies and power limits for NVIDIA directly using command-line parameters ( --gpu-cclock, --gpu-mclock, --gpu-plimit).
But honestly? On RandomX, this is more of a “sport” than a business. It’s usually more logical to send the GPU to algorithms where it excels.

🌐 Pools, payouts, and contributions to the Monero network 🧭

The Monero Project explicitly states that they do not “endorse” specific pools, software, or hardware ; the information is for reference only.
However, choosing a pool is both about money and decentralization.

Practice for profitability

Large pools provide stability in payouts, but can concentrate the hashrate.
Algo-switching (like MoneroOcean’s approach) sometimes increases profitability because it mines the “most profitable” and pays out in XMR—it’s a separate philosophy.
To “support the network,” many are looking toward more decentralized options (including P2Pool)—this is about the ideology and stability of the network, not just about numbers.

Commissions and “little things” that aren’t little things

SupportXMR is often mentioned as a pool with a fixed fee of 0.6% (after that, the payout conditions and thresholds become important).

🧠 Quick choice without guessing 🤝

In short (but to the point):

Choose XMRig if:

you want the most “reference” RandomX stack with strong documentation and clear debugging;
transparency and an open-source approach are important to you;
You are ready to carefully set up Huge Pages/MSR once and then just get on with your life.

Choose SRBMiner if:

you need versatility, multi-algorithm support, and experiments with CPU+GPU in one combine;
you like to control hardware parameters (including NVIDIA power limit from the console);
You’re comfortable with closed-source software and willing to pay attention to the nuances of the dev fee.

🧾 Final thought (a little personal)

I wouldn’t make a “religion” out of it. Real mining is boring: set it up, measure it, compare, and then stick with whatever gives you the best yield per watt and doesn’t drop at night . That’s it.
And arguing “which is better” without a wattmeter is like comparing cars by the exhaust note. It’s fun, but… well, you get the idea.
