TL;DR:
Seems stable, looking for any guidance or feedback on where to go next.
Looking for long term daily stable OC, but I also went delidded for the first time.
So it would be a shame to not make use of that.
And really really would need a fool proof guide on CPU OC.

Didn't get quite the engagement I was hoping for on a previous thread and I still have no idea what I am doing.
So I had to resort to a lot of chatgpt and getting bits and bobs from various guides. Overall though, I struggle to find any complete guide, nevermind one that is idiot-proof.
There seems to be a lot of conflicting information, or I just don't get it.
System specs:
custom water loop
delidded 9950x3d on liquied metal
Trident Z5 Neo 2x32GB – hynix M-Die – 30-40-40-96 DDR6000 (also water cooled)
I tried booting with ddr6200 and TCL28 but both individually or together caused errors and I don't know how to get them stable. The latency gain and bandwidth seemed somewhat minor compared to the voltage increase needed, so I decided to go back to ddr6000 and TCL30 and try to make that more efficient instead. That seemed to require a lot less voltage, figured less might be more, especially for a long-term stability goal.
Not sure how much improvement can be had here? Judging by the low voltages i reckon higher memory clock and/or lower TCL should be possible, no?
I Ended up with the timings in the screen.
9 hours TM5 ryzen profile, 8 hours VT3+FFT. No WHEA errors.
Seems stable, also at 1.05 VSOC though I only tested a few hours with that. 1.05 seemed low,so I walked that back one step to 1.10 to have a bit of a buffer.
As it turned out the reason I ended up getting this rig in the first place was simply low CPU voltage. Could not get a boot and constant random crashing after a few years. All I had to do was increase voltage… Rather not repeat that again.
LLC level 5
cpu and vrm spectrum spread disabled.

I did not do any dedicated CPU OC except for setting PBO to enhanced at level 2 thermals(80 degrees). I was hitting TDC limits at like 60 degrees in linpack extreme which I thought was weird. Now, in linpack, it hits around 75ish degrees at 194A TDC, 208A EDC. 45k in Cinebench R23.
I suppose the score has more to do with the delid than anything else? Ran a sweep of corecycler with VT3 at 6 minutes per core (3 hours), no WHEA error. No Curve Optimzer or anything else. No clock stretching that I can tell.
Could not find a good (and simple) guide to do any CPU OC.
Most I dismissed as I they recommend setting motherboard limits. Unless something changed since my last time, that is dangerous advice, and certainly does not help longevity.
Skatterbench has a post that is recommened bt that was way to deep for me and also seems to just remove limits. Didn't strike me as a daily safe guide?
And related to my previous post, I had audio crackling before but I think I fixed that now, turned out that the speaker audio sampling rates were not aligned. Needs a bit more testing but I haven't heard it since aligning them. Doesn't seem to be related to the memory overclocking.
