Miner: Kryptex native v5 (Cuckaroo29 backend).
MSI Afterburner: PL 75%, Core +100 MHz, Memory +200 MHz (optional; use 0 if you prefer the lowest VRAM heat), Fan 100%.
System: Windows power plan = Best performance, NVIDIA "Prefer maximum performance" for kryptex.exe/miner.exe, HAGS ON, AV exclusions for Kryptex folders.
Why this OC: Cuckaroo29 is core-driven and almost insensitive to memory. Core +100 with PL ~75% gives stable performance on RTX 4090 without unnecessary VRAM heat.
Stability rules:
- If you see invalid/shares or UI stutter → set Memory to 0 and/or reduce PL to 73%.
- If power rises without speed gain → PL −2%.
- Keep VRAM ≤ 90 °C and GPU ≤ 65 °C (typical on this profile).
Typical results on RTX 4090 (room ~23–25 °C):
- Power ~300–320 W
- GPU temp ~58–62 °C
- VRAM temp ~84–90 °C
- Reject/invalid ≈ 0
