If you have less than expected boost clocks, and/or get too low effective clocks (stretching) at default Vcore settings, then yes I would look into it. I believe the latest BIOS (1616) has this set to Enable which gave me some BSODs. For example, if you have a PPT of 75W, the processor will receive around 60W. 5. TLDR: My 7900x is stable (at least from 24 hours of torture testing and ovber 48 hours of normal usage) with a -30 Offset per Core. When you're done with PBO (weeks of testing each core by 1-2 offsets at a time finalized with 12h corecycler per core) you can try reducing EDC slightly and test between if you go down in several benchmarks (geekbench, occt is pretty quick). The only setting I've really done is enable AMD Expo, and adjusting the fan curves to how I like. Thoughts on 750W being sufficient or not? I've read that if I undervolt I'd be more comfortable in that range, but I'm not sure I want to fiddle too much with power for like 99% of pc users it makes more sense to have a power optimized build that sacrifices a couple percent performance for huge power drops rather than this full-bore crap amd, nvidia and intel have been pushing lately. Instinct tells me for 3090 and 7900X I should go at least 850W but then I miss out on quieter options. Anyone serious about productivity software that can use multi-core effectively and doesn't care about gaming should get a 7950X and anyone serious about gaming and doesn't specifically need multi-core productivity should get 7800X3D. Overclocking. Save, Apply. 08v. I idle at 30 in BIOS, or 39-45c in Windows. Disabling this lets me run EXPO settings 100% stable at the cost of 10-15 secs additional POST time.
