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.
crosshair tweak mode 2

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.

Found myself unexpectantly having to get a new rig and now that I finally have it physically together I am looking to do some overclocking, emphasis on some. I am looking for long term stability over raw performance. I was going to roll with whatever EXPO sets for voltages and see what that can run and call it a day.

I have no idea what I am doing and not looking to understand the ins and outs, just not to leave performance on the table. I am finding very mixed results when it comes to guides though and I'm not sure where to go next.

Foolproof extreme + EXPO tweaked

I found this "fool proof" guide and mostly followed that to step A3 with extreme settings.
I have not touched CPU yet or GPU, I was going to do RAM first. (only unlocked ReBAR I think). I got the F5-6000J3040G32GX2-TZ5N sticks which appear to be M-Die Hynix.
All I did was set EXPO tweaked, and then first optimal and now extreme settings from the guide.

That gave me roughly the same results as the optimal settings, more like a sidegrade.
Got similar latency and read on memory, but with higher read on l2 and ,lower write on L2.
But I just did 3 hours of Vt3 and TM5 with the ryzen 3D setting, so stable enough I suppose.

In terms of games there is probably not much more to gain here? But looking at some other screens it seems latency could be improved quite a bit still. If so, I would like to try for that. I found that to be rather noticeable on my last rig (DDR4 3600 4x8GB CL14 with I think around 50 ns iirc). Especially with boot times.

Both settings went without a hitch, I just set the values and tested for errors, so far so good.
But I would need some guidance on what to try next, before messing with FLCK. I reckon the latency can be improved with lower timings for example? To lock down timings before messing with FCLK?

But then there are also a ton of additional new settings since I last checked that I have no idea about but they seem mostly aimed at finetuning an already tightened set of timings for stability increases rather than performance?

RAM is watercooled. I ran the extreme setting with VT3 for 3 hours and the hottest they got was 37.8 with the loop running half speed fans and 90 l/h. I don't expect temp issues.

I wanted to see what people might have to say here before I go blindly copying numbers for others screenshots.

Noobclock round 2 - still looking for smarter minds.
