RamGuard
by Rener
RamGuard is a client-side Forge utility that checks whether the game has enough memory allocated before a player reaches the main menu.
What it does
Players who run a modpack on too little RAM often see slow or unstable sessions. RamGuard lets a modpack author set suggested minimum and recommended memory thresholds in megabytes, and it compares them against the memory the client has been given. When the allocation falls short, the mod can block access to the menu until the player raises it, which keeps a pack from launching under conditions it cannot handle.
The mod is built for modpack makers who want a clear warning built into the launcher flow. Its configuration covers the thresholds, the messages shown, the colors and text of the UI, and an external link that can point players to setup instructions. Memory values appear in the messages with automatic formatting, so an amount shows as MB or GB without extra work.
RamGuard works only on the client, so servers do not need it. It is released under the MIT License and is open source. The only published loader is Forge, and the only game version with files is 1.12.2, where version 1.0.0 was published on 2026-08-18.
Key features
Memory thresholds
Minimum and recommended RAM limits are set in megabytes, and the client is measured against both.
Menu access block
An option can require enough RAM before players are allowed into the menu, stopping launches that fall short.
Full UI control
Header text, line colors, button labels and button actions can all be changed in the configuration.
Memory placeholders
Placeholders insert the detected and required memory into messages, formatted automatically as MB or GB.
External setup link
A button can open an external page, so players are sent directly to the pack's setup instructions.

Use cases
Modpack launch checks
A pack author sets a minimum RAM level so players with too little memory see a warning before the pack loads.
Server-hosted pack guidance
Pack authors who host documentation can link the warning screen to the setup instructions for their pack.
Who it’s for: Modpack authors who ship Forge packs for Minecraft 1.12.2 and want to warn players about memory requirements. Players who install a pack that uses RamGuard see its warning screen, and no server setup is needed.

What the author says
Have you ever had players complain about crashes or low frame rates only to discover that they were using your 250+ ModPack with 2 GB of RAM? RamGuard detects this immediately upon launch. It saves you from repeatedly responding to troubleshooting questions by reading the memory allotted before the main menu loads…
