Also had one since Release. Booting 8800 wasnt any problem.
If u cant boot 8533 its another Problem, Not the board🤣
not every board is the same, that’s the problem with poor QC. The later production batches tightened quality up a lot more.

You can disable the channels, like I did.By pulling an individual stick? That’s what I meant in that post — with the sticks on water, it’s too time consuming with the small amount I have to spend on this stuff these days.
If there’s an easier way to do it.. that could be possible, like disabling the entire channel via BIOS, but I haven’t looked into that.
Believe me, I tried with 3 CPU, and 3 kit.Also had one since Release. Booting 8800 wasnt any problem.

I guess I was unlucky. But 8266C34 was pretty fast. 😊Broken one. One slot Not ok, got also one from Amazon.
But a normal apex can boot 8600 ez. Got 3 apex all first batch and all boot ez 8600+
You can leave the sticks in and disable MC1 or MC0 in BIOS.By pulling an individual stick? That’s what I meant in that post — with the sticks on water, it’s too time consuming with the small amount I have to spend on this stuff these days.

The boards trained timings are wrong quite a bit. I would imagine the tXP being too low has more of a negative impact than tCKE being too high, but who knows?I will try disabling a channel and testing that way if I can't find something stable by tomorrow. tCKE is set to Auto right now, just letting the board train it how it wants. tXP is 26 apparently; I will try changing that to 31.
None of my changes today have resulted in anything better than what I did last night; if anything it's made it worse. I reloaded the 10hr/3error profile, and raised DIMM VDDQ 10mv. I am now at a 40mv in-mem delta of 1.50v VDD/1.46v VDDQ. We will see if this helps.
Edit—it doesn't help. Error 0 @ 16min, lol..

Tm5, karhu und yc wäre interessant.Die 14600k können schon was ^^

Sry für die Bildqualität, aber war nur auf die schnelle mal eben abgeknippst.
Very likely VDDQ_CPU issue.It is the strangest thing. @tibcsi0407 @Veii
Around ~1hr, Error 0 popped up. I am busy and didn't have time to reboot and try new settings, so continued to let it run. It's now at 2hr 45min, and no further errors, just that single Error 0. Just doesn't seem to be any rhyme or reason to it. On this run, I raised VDDQ TX to 1.235v from 1.230v..
Inside mem, voltage is ok to stay 60mV apart ~ higher the better, depends on how good powering is.Any word on VDDQ deltas for 48GBx2 greens to start off with?
I’m unable to train beyond 7600 C36. Tested 1.41-1.5 Mem VDD and they all boot. SA around 1.16 (tried 1.05-1.2, they all boot) gives me the least training inconsistency. I used the 60mV VDDQ delta rule, but this might not be the correct application for dual ranks.
Use https://www.hardwareluxx.de/communi...-ram-oc-thread.1306827/page-442#post-30268285 as orientation example ~ for PoC@Veii
Thanks. I will try adjusting VDDQ TX downwards. I've tried higher values and they don't seem to help, or they make it worse. I didn't expect below 1.23v to be viable, but at this point, it's worth trying I suppose.
0081 is a good bios, exception is randomness on what feels like MR10 or RTT ~ one of both. Against that randomness "final" 1801 can be used.Ok yeah i was pretty sure 24/4 was correct which in the end i did have to swap it back to that to get my memory stable again so maybe it just brute forced its way past it in the first rounds of 1usmus? otherwise no clue but careful on 0904, the ME firmware def changed something for me and @tibcsi0407 - idk fully for him but i had to change a couple v/f points around, the main one being v/f #11 needed to go down or up 0.003 can't remember now, even reverting back to 0080 i had to change my v/fs to what was needed on 0904 again, prob will swap back to 0904 again tonight to test some mem stuff although I'm still on air so only so far I can go
Ok so did some quick tests before I gotta leave again, messed with some v/f points - think I got the hang of it for the most part (hopefully), though I did remove the 6400 for now cause I figured it would be easier to tune/learn the v/f stuff with just normal tvb for now, maybe i'll go back for the 6400 eventually but really wasn't needed
here is my cpus v/f and new updated curve after messing with some stuff

Hi @Vhypur, I hope you are doing well. I'd like to ask you if you can share me your V/F Offset. We have a very similar V/F factory curve, in my case I have a 14900k SP105, but the V/F are pretty similar. Veii suggested me to use your values. Thanks
I tend to drain residual power (power button with PSU off) before a cold boot between adjustments. Is that sufficient or do I have to cut power for a minimum time?Maybe it can be easier calculated
If you sample minimum delta and max delta
Then use like 75-80% of the value as "optimal level"
I guess, its near 75-100mV delta for 48gb dimms. Probably min 50mV max 150mV. Test and report back
Test in 30mV steps, make a cold-boot (psu off) .
A psu off (switch) is plentyI tend to drain residual power (power button with PSU off) before a cold boot between adjustments. Is that sufficient or do I have to cut power for a minimum time?
@perlibuverstehs nicht.
Hi @Veii! I'm also so so, but still pushing. Long story short, there was once a very happy OCN member with a good setup for his 13700k and 7200 with a Hero . But well, the desire to improve components and performance made me change everything. I bought an Encore, I managed to reach 8266MT/s with false stability, since by mistake, like many of us, I limited the voltage, in my case with an AVX offset, that's why YC never failed. Then I bought some 8000 2x16 Gskill A-die memories, to lower the voltages and temperatures a little, and until then, everything was fine. Then I bought the 14900k, which to my surprise and because it was a first attemp of purchase on Amazon US, I got a good one, SP105.Hello, Good timezone~
So so
You ?
Ok i see.
In such case you can just copy it from both either tibcsi or zebra_hun.
And slightly reshape it because mid-low differs too much between CPU binns.
That Blue bios looks soo strange.
Unusual
30mV step on P3 is huge
The Vmin was the same on new BIOS, but something was messed.* @@tibcsi0407 if curve got messed up , just increase AC_LL higher and problem is resolved.
It's that easy, hence we use a mix of both. So we can scale if whole substrate for memOC needs more voltage or not.
Much easier to linearly scale that way. Cleaner too.
You can try my current curve. I have AC_LL 0.65, so you can just lower that to reach your Vmin.My VF curve that I showed you in my previous post did not seem so stable, I think starting at 700mV is too low, I left that 15mV that you suggested. But in P3 I need to go up to at least +25 so it's not so flat. From then on it seems to me that the curve is well "rounded", but I don't know if 1320v for 6000 is not enough. I see the other users reach 6200 or 6400 in the end. Should I apply a positive offset to the rest? This would be my curve and now I'll tell you my nightmare with the OC of the memories.
heatkiller, kein Frame. Alles normal. Eingespannt, Kühler mit Federschrauben, u-Scheiben. Hatte nie Probleme bei dem.@perlibu
Wie ist deine CPU montiert.
Alles liest sich nach einem Socket-Pressure Problem.
Von meiner Sicht aus
Frame ja, nein ?
Welcher Wasserblock ~ Federschrauben/Abstandshalter?
Da wirst du nicht drum herum kommen, alles neu auszuloten.. also SA und CPU VDD/VDDQ. Womöglich war der IMC vom alten KS einfach gutmütiger?Hhm... vielleicht hat jemand tips. Hab die CPU getuscht. Alt: 13900KS, 1.488V 6 GHz VID - der hat 8400 easy mit 1.195V VCCSA, 1.375V VDDQTX, 1.45V VDDQ und 1.56VDD gemacht. ycruncher und retrain stable.
Jetzt ist ein neuer 13900KS drin, 1.422V 6 GHz VID und auf den P Cores auch taktfreudiger (e Cores und Cache etwas schwächer als er alte). Mein Speichersetting läuft nun überhaupt nicht mehr, was ich soweit sehen kann, ich brauche mehr VCCSA.
In welche Richtung würdet ihr gehen zum finden der Spannungen?
Hi @tibcsi0407, how are you? I couln't change my nickname here, I'm lmfodor@OCN.You can try my current curve. I have AC_LL 0.65, so you can just lower that to reach your Vmin.
You want to see ~flat line on the bottom and a double S shape after. For the bottom I like to set 730mV to have a little headroom. With lower Voltages I have stability issues.
P 2x60 5x59 7x58 +2 TVB E 8X46 16X45 R 0-50X
Core VID max is hugely differ from Vcore max, it's because my Pcore0 requests for higher Voltage for some reason. I have no idea why, that's not even getting the highest ratio.
