How hot is too hot for DDR5 RAM during stress testing and under full load?I've mentioned before but when you overclock, the MB can push some voltages too high which can cause stability issues. In my case that was the SOC SA voltage.
I have different system - MSI Pro Z890-A WIFI, 265K with 2x32GB but here are my settings:
IA CEP - Disabled
CPU Lite Load - Mode 13 (0.800/1.200 mOhm AC/DC LL)
P Cores ratio - Auto
E Cores ratio - Auto
Enhanced turbo - Auto (Disabled)
Ring clock - Auto
D2D - 3300
NGU - 3200
RAM - 6933 (6600 XMP)
VCC Core voltage - Offset -0.140v
P Cores voltage - Offset -0.100v
E Cores voltage - Offset -0.080v
Ring voltage - Offset -0.150v
SOC SA - 0.900v
SOC NGU - 0.950v
VccSA - 1.070v
VnnAON - 0.780v
VDD2 - 1.200v
CPU IO - 1.250v
RAM VDD - Auto (1.400v)
RAM VDDQ - 1.350v
The timings are more complicated because I'm using MSI Memory Extensions, in my case Memtest mode, which automatically sets certain timings and I'm manually setting just a few of them. There is a screenshot with the timings:

In your case with 285K probably you won't be able to undervolt VCC Core and P Core voltages that much. Some of the voltages probably are with different names and some others could even be missing.
Good luck!
With the 2x48 96GB G Skill M-die kit at 6400 MT/s with a few optimized timings, my RAM is hitting around 65°C to 70°C during the OCCT memory test, and it'll even spike up to almost 80°C for a minute or two. During Testmem5 and Y-Cruncher it peaks at around 65°C and sits mainly between 55°C and 60°C
Are those temps okay? If I overclock to 7200MT/s is it going to push temps too high under full load or during heavy stress testing?
My PC case doesn't really have the setup to be able to put another fan in there for my ram unfortunately and don't think I'm experienced enough to put my current ram kit in new heatsinks yet lol

I have no idea but in my opinion your kit is way too hot. It shouldn't be a problem but you won't be able to push tREFI to an optimal value. You can try to lower the voltage at the expense of the CL and the other couple of first primary timings.
That's mind blowing. Proof that I'm not the only lucky one with a great sample

It's going to get hot while stress testing, that's the whole point of stress testing. Test it under actual work case scenario, like gaming or actual workflow, for a couple of days and see what it sits at. But if it's still stable at those temperatures without any issues it should be fine under normal use case. But if it still hits those temperatures under normal use case, you're definitely going to have to get some air flow to them or make a compromise somewhere.
I have a custom RGB profile that I run that adds 10°C that I use for testing just to find the thermal ceiling. I'm running G.Skill kits with stock heat sinks that do not have thermal pads on the PMICS. They will gladly hit 71°C to 73°C during testing, but at idle they are at 25°C, and normal use case they are 35°C to 55°C. Zero issues.

Is there a control for these voltages on the Z890 Unify-X? I couldn't find any options on my PRO Z890-A WIFI.
EDIT: Founded in the "Misc Volt Item" under the Advanced DRAM Configuration menu. But the values are weird from 1 to 65535, have to figure it out how it works

Post showing that M3 Max throttles while M4 Max doesn't. M3 Max is based on N3B, the same process used for Arrow Lake compute tiles. Guess Intel has a knack for cursing itself inadvertently?

You are fine at 70°C PMIC, at default tRFC on 32767 tREFI.
It is also fine to use tighter timings on still JEDEC-like tRFC.
Most ICs are rated till 80°C (PMIC), or around 95-100°C pure.
You will have 3 stages of issues. PMIC above 42°C, above 55°C and above 70°C
Passing 70-72°C and you are fine for HOT targets.
So what you say is: watercooled dimms is still meta 😁
There is a new MR and uCode around the corner:

Or you can just do what I do in my home office with twin A4-H2O's stacked one atop the other.. they sit on the left end of my desk directly next to the office window, I run a 450w dedicated window air conditioning unit that blows directly into both of them and keeps abient room temps at 65°F-75°F. Ambient room temperature stays incredibly consistent throughout Michigan seasons with outside temps from 95°F to -5°F. Typical ambient of 65°F-68°F under usual use case, and 72°F-75°F if gaming all day long.

I don't know
I was hinting that tRFC isn't such a big factor in terms of performance and memory remains scaling with tighter primaries.
Else that HOT stability is unforgiving on tRCD.
You will struggle above told 3 targets till you fully stabilise it.
Once after the 2nd hour mark and once approaching ~5h, 4:20-4:50h somewhere there.
There are quite some margins on colder temperature.
XMP verification in general should target HOT stability past the 6h mark
EDIT:
Oh also hinting that most 55-70°C issues are not due tREFI
Its very often bad powering.

Is that on your Gigabyte motherboard? I've tried adaptive + offset but I wasn't able to stabilize like I was with per-core adaptive and setting the SVID (without offset) -- in part because my Gigabyte motherboard doesn't have full per-core VF tuning like the Asus featured in the skatterbencher guides

I needed higher voltages in this mode compared to fixed voltage. But the power draw is less.

What is "bad powering"? Some problem with mobo power delivery?EDIT:

Impedance mismatching of 70 traces from PHY out to DDR5 Slot
so also Dynamic, Parked & Nominal RD/WR state.Well over-generalized term for any non-time related synchronization target.
TX (transmit) vs RX (receiver) DFE falls into it.
Else time related ones can mean,
bad Vref ↕ margins, badly trained comp (very common issue unfortunately) and co.
I do call powering mostly non time-related targets.
Mostly Ω mismatching of signal send vs termination received, as (V) target alone doesn't matter too much.
Causing back-reflection or (more common again due diff-temp targets) dropping out before receive
EDIT:
NEXT & FEXT are rarely issues on consumer side. Even at "hot above common-sense" targets.
It's very commonly just either trace delay (due capacity & cold-targets) or straight impedance mismatching,
due skewed targets between PCB design vs common voltage base on MRC ↔ DIMM.
Every DIMM-PCB is unique and even unique between SKUs of the same Vendor.
#30,437 and a few more (recent) posts are interesting on the same manner.

I have a funny feeling that the 285K is better than what YouTube(rs) betray(s), Warhammer mirror of madness, 500fps avg with 443 or 434 (cant remember) minimum, which is better than what i got on a 7700, 458 avg and minimum into the 340-350s.
Supposedly the 3d cache doesn't help in this benchmark but I'll test it myself.
Talking about this specifically:

I'm not convinced his 285k system was set up properly. He not only didn't overclock optimally but crippled his 285k with 24h2.

Tech media turds.
A 265K competes no issue at all with a 9700X in gaming, and blows it doors off in literally everything else.

He is a clown and he is brain dead right now.
In his testing, the 14900K can only hit 3000 fps in shawdow of tomb raider 1080p built-in benchmark while my 13900Ks can do 350.
With some tuning, it can hit 370.
I don't know how he got those numbers.
And besides, in his testing of the 5090 waterblock, his water temp was above 40C.
What is he doing? Is he trying something innovative like hot water cooling?
