Pearl mining settings for RTX 30/40/50

One card measured, the method for all the others. No magic numbers copied from screenshots.

RTX 5070 — measured

Setting	Value	Why
Power limit	190 W (~76%)	heat drops, hashrate almost unchanged
Core offset	0	algorithm is not core-starved
Memory offset	0	stability matters more than a benchmark
Fan curve	60% < 70 °C, 80% above	quiet idle, real cooling under load
Thermal guard	throttle 78 °C, stop 85 °C	keeps the card alive unattended
Result	~124 TH/s, 74 °C, ~80% fan	Pearl (PRL), SRBMiner-MULTI

How to find your numbers

Start at stock power. Watch hashrate and temperature for 10 minutes.
Drop the power limit in steps: 100 → 85 → 75 → 65%. Note TH/s and watts at each step.
Pick the point where TH/s per watt stops improving — that is your sweet spot.
Only then try small memory offsets, and check rejected shares after an hour.
Set the guard before you leave the rig alone: throttle and stop temperatures.

Every card and every room is different. A 3060 in a cold basement and a 4090 in a closet need different limits. The method is the same; the numbers are not.

Why heat beats hashrate

A card at 80+ °C for months loses value faster than the reward drops. Fans at 100% wear bearings and still cannot fix bad airflow. Power limit plus a curve plus a guard is the cheapest reliability upgrade you can make.
