Each CPU has multiple chiplets. My 5800x was running a ridiculous 1.328vcore under full-load and 1.288vcore under Prime95 load. But if you want to overclock, as Azulath said, go with Curve + PBO. They also share a large 32MB L3 cache. While not all processors are innately capable of reaching . Got a 5900x on pbo with curve optimizer, got a 240mm ek aio with push/pull fans in a sealed positive air pressure case with filtered intakes (absolutely a must if you have a lot of furry animals running about like I do) and ambient temp is 24C. However I was curious about LLC setting and Digi+ in general. This will be our Current Threshold value for Dynamic OC Switcher. Hi I have a 5900x on a Dark Hero board, i'm using PBO + curve optimizer with those settings below and I have an EK AIO 360 . While AMD offers aggressive frequency boost for single threaded applications, it does not offer to set the single threaded boost frequency when manually overclocking. It took me some time and alot of stress tests to figure out a stable setting: Curve optimizer magnitude (-20, -10, -25, -25, -25, -20, -20, -10). Afterward, find the maximum stable frequency for that voltage and temperature. Im told rumour the prior dynamic oc switcher which was x570 exclusive to the asus dark hero motherboard only will be in the future present in many asus motherboards for am5, Being a dark hero owner myself, all the tweaking on my own 5950x showed a direction involving PBO2 + CO + OC infinity fabric and RAM + under volting gave the best outcomes.has anyone done better in measurable ways using dynamic oc switcher? Something tells me these CPUs are going to be switching to all-core when you want PBO, and be too slow and stupid to switch out of boost when you want all-core. Dynamic OC Switching allows us to ehr, dynamically switch between Precision Boost Overdrive and OC mode. I tried a lot of settings: All core and single core undervolting, from values around -5 to -30. Set CPU power draw limit to near max in bios, Scan this QR code to download the app now. Hi I have a 5900x on a Dark Hero board, i'm using PBO + curve optimizer with those settings below and I have an EK AIO 360 .

When this happens, check the CPU current in HWinfo. Yeah, sounds like a mounting / thermal paste issue. Also, you can not configure the boost frequencies by specific use case (i.e. Lastly, by default the fabric, memory controller and memory frequency operate in synchronous mode. The much-touted-by-everybody EDC trick never worked for me, because it's not even remotely stable. 1.3 is average for speeds of 4.7 if you want to try locking the cpu to avoid the high heat, you won't get individual core boosts but you will have much less heat at the top end. I am using PBO for some nice single core boots of over 5GHz, and then using a manual overclock using the Dynamic OC function to switch from PBO to manual OC at a desired current draw, great how the Dark Hero supports best of both worlds! in gaming? With the benefit of custom l. Gradually increase the amount of Prime 95 threads until you see the operating frequency drop below your desired manual overclock. First thing, it's one of most powerful CPUs, chances are that you may not need any classical OC at all because of it's fast and aggressive boost but instead familiarize with and concentrate on most effective settings in auto-boost modes. This is the first overclocking trade-off: settle for lower single threaded performance with higher all core performance, or the other way around. Ryzen handles voltage different to what I'm used to on Intel platforms. One way of identifying the right trigger point is to check the CPU current during a benchmark workload. It adjust the fit voltage limit set by amd for boost algorithm. For more information, please see our All the chiplets communicate each other via the fabric interconnect. Reddit, Inc. 2023.
