RAM is one of the easiest places to either overspend or get burned by buying too little. For a Malairte mining PC the honest answer is "less than the marketing implies, but with some caveats worth understanding." Let us break it down by what each part of the rig actually does with system memory.

What GPU mining uses

The GPU mining process itself leans almost entirely on the card's own VRAM, not your system RAM. The miner executable, the driver, and the operating system together hold a modest footprint in main memory. A single-GPU mining session rarely touches more than two or three gigabytes of system RAM on its own.

What CPU mining uses

CPU mining is more memory-sensitive, because many CPU-friendly algorithms are deliberately memory-hard to resist ASICs. Each CPU mining thread wants its own slice of memory, and on a memory-hard algorithm that slice can be a couple of gigabytes per thread. If you intend to mine heavily on an eight-core CPU, your memory needs climb quickly.

What running a node alongside uses

If you run a Malairte node on the same machine to validate and relay, budget another couple of gigabytes for it plus the operating system's file cache, which the node benefits from heavily.

Sensible capacity targets

  • 16GB: comfortable floor for a GPU-only mining PC running Windows and a single card
  • 32GB: the sweet spot if you also mine on the CPU or run a node alongside
  • 64GB: only worth it for heavy multi-thread CPU mining on memory-hard work

Speed and channels

Memory speed matters more for CPU mining than GPU mining. Run your kit in dual-channel — two sticks, not one — and enable the XMP or EXPO profile in BIOS so the RAM runs at its rated speed rather than a conservative default. The difference between single-channel and dual-channel can be meaningful on memory-bound CPU algorithms.

What not to waste money on

RGB heat spreaders, exotic low-latency kits, and four-stick configurations chasing tiny timing gains are not worth it for a mining build. A plain, reliable 32GB dual-channel kit at the platform's rated speed covers almost every home scenario. Spend the savings on a better GPU or a quieter cooler instead.
