5800x3d undervolt reddit My 5800X3D is only stable at -15 CO, so I used power limits to reduce temps a few more degrees without losing any performance. Thanks in advance. I could not tame the 5800x3d with the L9a. The memory controller slows down when you undervolt it, and since the VDDG voltages are derived from it, you also inherently must undervolt them ever further to hit the 40-75mV target distance between the steppings (SOC -> IOD -> CCD). Some guy suggested I go in BIOS and undervolt CPU by 0. Undervolting my 5800X3D was the best thing I've done in terms of tweaking my PC. 0.

I don't have a great airflow though, three front fans, meshed panel and a rear fan on a pretty tiny case but my temp are pretty satisfying imo, the 5800x3d can run way hotter. I've changed PBO2 to advanced and curve optimizer to negative 20 allcore and it seems pretty stable for an undervolt. Any other possible instabiity will also affect how far you can undervolt, those being FCLK and SoC/IMC On most motherboards, Auto LLC gets you the best -CO results. I've tried undervolting it with the Kombo Strike feature set on 3 in the horrible MSI bios interface (not the pretty red one I once had) but i feel nothing has changed. 35V (F4-3600C16D-32GVKC) - bios: 2. co Hello!

People are generally using the curve optimizer in BIOS for that -15 or -30 stuff. Since the 5800X3D is locked, you can't really do a whole lot more. My sample runs -30 on curve optimizer for all cores, which equates to an undervolt range of -90mV to -150mV (Curve Optimizer is a semi-autonomous undervolting method, which is why it works in terms of a range, with -3mV to -5mV per tick). curve gibt's bei den meisten boards erst ab agesa 1. The benefits of using a 5800X3D is the 3D cache. Just open bios, go down to voltage, and see if you can do "offset" instead of "auto".
