i never actually even been on ddr5 on air until last month. even during ES kit i went straight water.

Air is terrible. its harder to diagnose the cause of instability.

Asking again maybe i didnt express myself correctly, what would be safe daily long term voltage limit for Hynix M on Air ( which never broke 42c++ ) 1.55v or 1.50v ?

the ram bsod if hot
pmic has a temp that will bsod

so.. again depends on your cooling
i run 1.65-1.7v 24/7 for months

An update from me after my frustrations with failing XMP RAM stability tests:
Perhaps maybe the lower heat spreader underneath the Noctua NH-D15 Fan is better for my setup as well as the Trident Z5 are taller and less room to maneuver the NH-D15 fan.

commenting for first time because of the D15 LOL!
i had one many years ago so i understand but as soon as i read your comment i was like ohhhhhhhh....
it does sound like your ram kits are not getting enough air flow. i had to learn that the hard way myself
and I'm on a external water loop direct die with a ton of phanteks t30 fans lol!
I've had the Samsung, M die and now A die Hynix.
i would like to learn how to water cool my gskill 7200 kit.

Is it a DDR5 problem or any RAM problem. Cause I refuse to do any water cooling!!

I have only had problems thus far with DDR5 not even CL14 3600 Samsung B.Die DDR4 at XMP behind the NH-D15.

ok, I thought you were just getting errors. My unifyx wont post 7200 with cpu vddq/vdd2 in increments up to 1.55 and dram vdd/vddq up to 1.65 and very loose primary/secondary settings, only way Im posting 7200 mdie is with another mobo or cpu or both.

A die easier to run higher frequencies, stable 7400c34, but 7600 no post.

I can post and daily stable 7200c32 m-die on unify x

Don't have newer screenshot but lowered RDRD and WRWR TO 15. Also changed tREFI to 120***. Can't recall exact number. And tRAS to 30. Scores even better.

I am at a tipping point and near ready to go back to DDR4 with my DDR5 frustrations. Though I really want 6400 CL32 or faster to work as per Gamers Nexus it does provide a gaming boost in CPU limited situations.

Is the bottom line that to get DDR5 at 6000MHZ or faster Samsung or Hynix kit fully stable, is active cooling needed or at least extremely high case airflow so temps never exceed 40-45C something on SPD Hub in HWInfo64?? Or is that not necessarily true??

Would it be worth purchasing a 2 DIMM board like the MSI Z690 Unify X and could that help a lot.

Or is it a lost cause if I insist on using a Noctua NH-D15 cooler with 2 140mm fans to cool my CPU which makes space much more limited near RAM and maybe restricts airflow and just better off going back to a good DR4 Samsung B.Die 3600 CL14 kit.

Or is it too hard to say??

when you share nothing but primary timings and speed , it’s hard to understand what you actually are testing.. 👍

scaling. voltage. mhz. understanding adie
simple thing ppl cant even seem to answer cause everybody chasing mhz.. etc

timing .. it all depends on your rams. i dont see any point posting it cause timing is all about cooling etc.

simple question right now, whats a good bin adie? whats a golden bin adie? whats the mhz scaling?

yeah, some unify-x/cpu imc combos can run 7200 or higher on mdie and 7800+ on A die, some cant. my unifyx/cpu/imc combo tops out at 7000 MDIE and 7400 Adie, just typical variation in motherboard and/or IMC capability.

And not surprisingly, your 7200 mdie works with reasonable voltages/tight settings, which is typical... ie if it is going to post it is usually effortless with scaled voltages/loose settings, then tighter from there. If scaled voltages/loose settings dont post, instead of beating a dead horse, you need to find and replace the limiting factor, whether that is cpu/imc, mobo or ram.

Anybody a bit more versed in DDR5 able to help get these sticks stable on my 13900K?
I bought this kit and crossed my fingers:

F5-6400J3239G16GA2-TZ5RK
https://www.amazon.com/dp/B09QS2K59B

Even at stock settings, with XMP enabled, I'm able to boot, but fail shortly after starting an AIDA stability test with CPU/FPU/CACHE/MEM checked.
With XMP disabled, I'm able to run an AIDA64 test all day (Stock 4800MT/s)

My MOBO is the Gigabyte Aorus Z690 Ultra

I have tried lightly boosting the VCCSA but figured I would ask here before I go pushing numbers too high. I am aware that there is a VDDQ CPU and VDDQ2 which (correct me if I'm wrong) are the memory controller voltages for the CPU and DDR5 "on die" controller, correct? Any setting I can enable or voltages I can increase to try and get this kit stable? Thanks in advance!

Fellas, I'm looking at the Bitspower DDR5 kit or Bartxstore.

Bitspower:

Bitspower 2-DIMMS RAM Water Cooling Module (DDR5, Single-sided)

Bitspower 2-DIMMS RAM Water Cooling Module (DDR5, Single-sided) The RAM covers only fit for single-sided DDR5.

Bartxstore:

Custom RAM copper heatsinks for DDR5 / DDR4 - Bartxstore

Custom made copper RAM heatsinks for memory extreme overclocking using dry ice or LN2. Designed for DDR4 and DDR5 memory
bartxstore.com bartxstore.com

The thing with the Bartx is that it's direct contact on the memory IC. Bitspower uses thermalpad for the IC. Might be better pressure with the thermal pad contact. In the past I've found that direct contact with memory IC can be hit or miss depending on the soldering tolerance of the PCB.

Another vendor I looked into is the Supercool one, but no stock. Between the Bitspower and Bartx, which would you guys lean towards?
