On my 5950X I see about the same voltages, etc. no matter what I set the scaler or boost max to. Once PBO is set to motherboard limits changing those does not change what my CPU does. Using +200 boost max seems to cause it to run slightly slower.I didn't say it was completely stock. I said scalar, boost max, and CPU voltage were stock. We have people running around with 10x scalar, positive vcore offset, and maxed LLC - that's going to be way more wearing on the CPU than leaving those things alone.
I was simply pointing out that you can get these CPUs to run a very aggressive voltage/load with a curve optimized PBO, more than you might expect. A positive voltage offset or crazy LLC settings would be pushing harder, but you can get a very strong push (high voltages) out of PBO without messing with those too.
Huh? The point of TDC is to drop the power so you do not overwhelm the cooling (maybe VRM cooling, but it is about cooling). The is why it exists. The VRMs are so overkill on X570 OC boards that they aren't even a concern. You would destroy the CPU before they even get hot.Because that's how power delivery works. Those are motherboard delivery specs to let the CPU know what's available. Surely the VRMs are not able to deliver the same continuous current as they are able to deliver peak/spike current. So if someone is just running with these numbers at maxed values so as to be "uncapped", then that's fine and dandy. But running TDC higher than EDC makes no sense whatsoever - which is exactly what I said in my original post.
Running a TDC below EDC makes no sense whatsoever, at least not on a custom water cooled system with overkill VRMs. What do you gain?
Well, I get better benchmark scores for one. Also, lower temps. A negative curve offset causes the CPU to use higher clocks and more voltage for higher power loads (as does PBO itself), so I like to drop that some. I have run without the voltage offset. Without the offset I need to use slightly higher (less negative) curve offsets to be stable; performance is only a tiny bit better in pure single threaded benchmarks (~1 point in CBr20) and worse in multicore benchmarks.Why? It doesn't appear to be too much for AMD at bone stock settings, so why do you feel it's too much for you?
I don't think that is true. It is well known you need to benchmark Ryzen to validate an OC. It is easy to get it to clock higher but score worse, as you have seen.But the problem I've noticed is that's everyone is all about what boost speed they're getting and judging their OC on that, rather than about what performance numbers they're achieving.
But most of the time clocks do equal performance.
