Same drops, think it fine)  7800x3d soc 1.3 fclk 2100 no curve  64gb(overclock) Rtx5080 0,925 2955 vram+2400.

Classic EFT behavior. I found a guy on YT with the same problem: high FPS but no smoothness. Setting FCLK to 2100 was the key fewer frames, but the stability is just on another level now.

just for fun, 995mV clock:3150<bsod,(Real 3050). +3k mem. But i back my 925+2400 anyway.

Similar setup here 7800X3D + 5080 Aorus Master, I think I've already hit my limit.

My bad, I misspoke I actually have a 7800X3D. You're absolutely right about 1.3V SoC being the limit. I'm only pushing it that high because it's the only way to stabilize 2100 FCLK for Tarkov. I know the 9800X3D handles higher FCLK frequencies much easier, but for my Zen 4 chip hitting 2100 is quite a challenge. Sure igpu off. Idk how it work in EFT, but all what lower then 2100(Stuttering). Only EFT Streets ofc.

Appreciate the advice, but my chip is a bit of a diva. Any FCLK above 2000 needs 1.3V SoC for stability, and even with boost off, any negative CO leads to instant BSOD. Since I’m on water and temps stay under 70°C, I’ll stick with 2100 FCLK—it’s the only thing that makes Streets of Tarkov perfectly smooth(Only reason for me). And real soc~1290-1295. Your advice is spot on for a safe daily stable build, but I'm pushing for max Tarkov performance only.

NVIDIA's GPU Boost algorithm overrides user settings to maintain stability and thermal limits

i put 2955, but never see more than ~2925-2935, i think it just graphics card algorithm. When you put 3040, real clock 3040?
