XFR: Enabled. From what I’ve come to understand, high end CPUs like the 5950x or even ones like my 5600x don’t gain anything substantial when overclocking for gaming. My power PPT hovers around 170-175W according to ryzen master. I did all core clock fir awhile but was not very power efficient and disabled a lot of the safeguards of pbo. 8 Ghz (all core) during Cinebench. But I feel like I'm not getting the results with PBO, or more specifically the Curve Optimizer. I use Auto OC but my offset is +200 MHz so I'm running 4. Curve Optimizer set to All Core -20. 5950X PBO 300 230 230 AutoOC 100 Curve Optimizer -15, max temp 81c. Reply. Now if you go back in and up the power limits, apply a scalar, and set a nice It should be an even better option for overclocking. Seems to me that for water or air cooling any decent board will do, even for the 5950x. Ambient air is 18 C, Inside chassis air is 36 C, AIO radiator is 41 C. While the 5600x and 5950x were an all core negative offset of only -12. 5C with highest clock speed at 5075MHz, let me know your thoughts, cheers. What gives? Could it be the motherboard, CPU or something else? PC Specs: • CPU: AMD 5950x. However, I've tried messing with PBO, override +200mhz, scalar 4x, limits set to motherboard, didn't mess with any curve optimizers. ADMIN. 8-4ghz multi and runs cool as a cucumber, needs increased power limits to stretch its legs. 0GHz. I have a MSI x570 Tomahawk WiFi motherboard and I recently upgraded the bios which was fairly old. 494v. 3Mhz CB: 29k score. 5 or not All core for lower temps and better multi core performance. Amazing what a chiller does for the 5950. 6GHz. Clocks are @ 3. With PBO enabled at the default settings I get a 28k score in Cinebench R23 Ryzen 9 5950x 2x16gb gskill trident z royal elite 4000mhz cl14 gigabyte x570 aorus xtreme Load up BIOS defaults, go into PBO menu and enable advanced. When you're done testing all cores, test with medium, SSE, extreme, all cores. I have tried numerous settings and can barely get 4. Maybe 4. Other times, stay on PBO. I ended up with a 150MHz boost overclock, and an all core boost of 4800Mhz +/- 50 depending on workload. The chip is limited by it's TDC and EDC, running into it's 140A and 95A limits by the time it hits 125W actual power consumption (it doesn't even max out it's 142W PPT under an all-core load). Your preferred clock appears to be 4. So I had a 5800x but I do work that requires more cores. Not many people know about this. I think I have the slowest 5950x and sold my amazing 5800x. Various settings from 118-125-stock ppt, 75-90A TDC and 115-140EDC, with the lowest settings there giving best results in cinebench. And 2: dont know how dynamic oc works,being an Asus dark mobos exclusive,but from a 1 minute search on internet, it helps a little in single core perf. Any form of overclock on the 5000 series will have worse single core performance compared to using PBO2 and undervolting each core individually. - Putting the PBO limits to "Disabled" or "Motherboard". 15v, peaking mid-70's) for multi core, slightly lower single core. 3 and temps reaching 100 max during stress testing. All cores seem capable of boosting to at least 4,900MHz and under all-core load (CineBench / Prime95) I get 4. Set small data set, SSE, variable load, and set affinity to the core you're testing in Task Manager (mark both threads). Yea, you can limit the power draw by lowering the PPT/TDC/EDC limits in the PBO overclocking section. tx da zq xk mf tr pv sg am un
