Seeking optimal MSI Afterburner settings for RTX 3090 during intensive LoRA training

I'm using a GeForce RTX 3090 ASUS ROG Strix OC Edition (previously used for mining) for LoRA training, which is pushing the card to its limits. My setup:

• Windows 10
• 64GB RAM
• ROG Crosshair VIII Hero MOBO

Issue: Memory temperatures spiking past 100°C during extended LoRA training sessions.

Current solution:

• Using MSI Afterburner with a voltage curve based on this video: https://www.youtube.com/watch?v=SIlXT32fOMk
• Results: Memory temps now between 94-96°C, GPU and Hot Spot temps down by ~3°C

While this is an improvement, I'm aiming for even lower memory temps for safer long-term use. I'm willing to trade some performance for better thermal management.

Questions:

1. Does anyone have experience with optimizing RTX 3090 settings specifically for ML workloads like LoRA training?
2. Are there better MSI Afterburner curves or settings you'd recommend for my use case?
3. Any additional tips for managing VRAM temperatures on the 3090 during intensive, extended workloads?

Thanks in advance for any insights!
