Hey everyone, I am new to reddit so i dont know if this is the right subreddit. I’ve been tuning my system for better performance + efficiency and wanted some opinions from people who know their stuff.
Specs:
- GPU: RTX 2070 Super
- CPU: i5-12400F
- RAM: 32GB (2x16GB) Corsair Vengeance DDR4 3200
- Mobo: ASUS H610 series
GPU Tuning
- Undervolted using MSI Afterburner curve editor
- Current behavior:
- ~1950–1995 MHz core clock
- ~130–160W power draw
- Temps ~70–77°C under load
- Goal: keep near-stock performance but reduce power/heat
Observation:
- Very stable in games (Spider-Man 2, etc.)
- But Blender (Cycles GPU compute) caused system-wide lag once (GPU/CPU usage dropped, Windows at ~3 FPS)
CPU Tuning
- Adjusted power limits in BIOS:
- PL1 ≈ 125W
- PL2 ≈ 165W
- CPU boosts properly (~4.0 GHz all-core)
- Temps under control (~60–70°C gaming)
RAM Tuning
- Running DDR4 3200 MHz (Corsair Vengeance 2x16GB)
Primary Timings:
- tCL: 16
- tRCD: 18
- tRP: 18
- tRAS: 36
- Command Rate: 1N
Secondary Timings:
- tRFC: 500
- tREFI: 65535
- tFAW: 24
- tWR: 12
- tRTP: 8
Notes:
- Voltage is on AUTO (H610 limitation)
- Gear mode not accessible (assumed Gear 1 at 3200 MHz)
- Stability tested in games (no crashes so far)
Observations:
- Noticeable improvement in frametime consistency
- Better 1% lows compared to XMP/auto
- System feels more responsive overall
Open Questions:
- Can tRFC be pushed lower safely on this kit?
- Is tREFI = 65535 safe long-term?
- Worth tightening further vs attempting 3600 MHz?
In-Game Performance (Spider-Man 2 PC)
- Very High preset
- DLSS 3.1 Frame Gen ON
- Dynamic resolution scaling ~45
Results:
- ~90–150 FPS depending on scene
- 1% lows ~80–100 FPS
- GPU usage ~95–99% (mostly GPU bound)
Issues / Questions
- GPU undervolt stability
- Stable in games but crashed/bugged out in Blender
- Is this normal for compute workloads?
- Memory overclock scaling
- Tried +900 MHz VRAM → almost no FPS gain
- Is this expected for this GPU?
- RAM tuning headroom
- Worth pushing 3600 MHz on H610 + 12400F?
- Or tighten timings at 3200 instead?
- Overall balance
- Am I CPU limited anywhere?
- Or is this a well-balanced config now?
Goal
Max performance without unnecessary heat/power, but still stable for both:
- Gaming
- Light Blender work
Would appreciate any suggestions on:
- Better undervolt curve
- RAM tuning (primary/secondary)
- Anything I might be missing
Thanks 🙏
I would be happy to post benchmark results from CapFrameX and run additional benchmarks and tweaks later. Any help is greatly appreciated.
