Builder’s Buying Guide: Fitting It Into Your Rig
Check Compatibility First
Confirm the memory kit plays with your platform and the rest of your 2026 parts before buying — get sockets, sizes, connectors, and clearances lined up first.
Match It to Your Budget
Spend on the memory kit in line with how central it is to AI workloads, then settle on the tier that weighs cost against room to grow.
Plan for Upgrades
The right memory kit buys you upgrade room, so go with one that won’t strangle a future swap and stays useful for years.

Frequently Asked Questions
How much memory do I need to run local AI models?
It depends on the parameter count and quantisation. A quantised model at four bits needs roughly half a gigabyte per billion parameters plus context overhead, so a seven billion parameter model fits in a few gigabytes while larger ones need tens. Thirty two gigabytes covers casual use, sixty four gives real headroom.
Does memory bandwidth affect generation speed?
Heavily, when the model runs on the processor rather than the graphics card. Token generation reads the entire weight set for each token, so throughput scales almost directly with available bandwidth. That is why a faster kit and both channels populated make a much bigger difference here than in normal desktop use.
Should I put the model in VRAM or system memory?
Graphics memory whenever it fits, because its bandwidth is many times higher. Offloading spare layers to system memory extends what you can load but slows generation noticeably. Size your setup so the model you use most often fits entirely on the card, and treat system memory as overflow.
Do I need special AI memory?
No. There is no separate product category. A standard dual module kit at the speed your platform supports reliably, with the profile enabled, is exactly right. Spend on capacity and on a graphics card with more memory rather than on exotic high clock kits that your controller may not run stably.
What is the sensible upgrade path?
Start with two modules totalling thirty two or sixty four gigabytes so both channels are populated and two slots stay free. If workloads grow, adding an identical kit is safer than mixing, though be aware that four populated slots usually force a lower clock and therefore lower bandwidth.
