🤔 What Is RAMUP?

RAMUP is a Linux memory extension engine that makes your cheap VPS behave like it has way more RAM — for free. It combines ZRAM, smart swap, kernel tuning, and a real-time auto-adjust daemon to squeeze maximum performance out of minimal hardware.

Your VPS (4GB RAM)  →  After RAMUP  →  ~11GB Effective RAM
Cost: $0
Time: 30 seconds

No kernel modifications. No proprietary software. Just proven Linux features, automated and optimized.

🎯 How It Works

1. 🗜️ ZRAM Engine

Creates a compressed block device inside your RAM. Data gets compressed at ~2.5:1 ratio.

2. 💾 Smart Swap

SSD-aware disk swap as overflow. Auto-detects SSD vs HDD. NVMe swap is fast enough for most workloads.

3. 🔧 Kernel Tuning

Optimizes vm.swappiness, vm.vfs_cache_pressure, vm.overcommit_memory, and dirty ratios.

4. 🤖 Auto-Adjust Daemon

Systemd daemon monitors memory pressure in real-time: Low → Medium → High → Critical.

---

📊 Smart Sizing

Your RAM	ZRAM	Swap	Effective
512MB	768MB	1.5GB	~2.7GB
1GB	1.25GB	2GB	~4.2GB
2GB	2GB	3GB	~7GB
4GB	3GB	4GB	~11GB
8GB	4GB	6GB	~18GB
16GB	5.6GB	8GB	~30GB
32GB	8GB	11GB	~51GB
64GB	9.6GB	16GB	~90GB

⚠️ "Effective" includes ZRAM + swap. ZRAM ≈ real RAM; swap on disk is slower.

🛡️ Safety

1. 📸 Backup First — Full backup before changes
2. 🧱 Proven Tech — Standard Linux features only
3. ⏪ One-Command Rollback — ramup off or ramup restore
4. 🛡️ Safe OOM — Never kills apps unexpectedly
5. 📝 Full Logging — Every action logged
6. 🔄 Upgrade-Safe — Clean upgrades over existing installs

---

⚠️ Important Notes

• "Effective" RAM ≠ "Real" RAM — ZRAM ≈ real RAM; swap on disk is slower
• Swap on HDD is slow — Use SSD/NVMe for swap
• Overcommit risks — vm.overcommit_memory=1 may trigger OOM killer
• Not a replacement for real RAM — Helps survive spikes, not sustained pressure
