At 3000 cr1 cl 14 flat bar was like that
seems strong enough. Usually imc can handle the signal when this bar is 27 and above. You can place a sticker on the screen to mark the divisions.

Is this the validation you are referencing with that image? He used liquid nitrogen, with very high voltages, only one SR stick, 2T command rate, etc.



I'm not saying MSI boards are bad or anything of the sort. They make some damn good motherboards that are amazing at reaching high speed frequencies with B-die (SR & DR).


I was hoping MSI's Z490I Unify would be able to handle DR B-die @ 4000mhz+ / 1T with reasonable voltages / cooling for daily usage. Unfortunately, it doesn't seem like it's any better than ASRock's Z490 lineup in this regard. Hopefully a BIOS update changes this, but I'm not holding my breath...

Hi,
Nice, but you don't need hours of testing RAM stability.
Just need to increase RAM temperature to find highest stable temp for your settings you are comfortable with.
In your case, after 12 hours of testing, it's possible to crash in just few minutes when playing games for instance, because of the GPU throwing hot air on the RAM modules...

Everything is fine with games. The prime95 for 12 hours was with a large FFT setting, one and a half to two hours of memtest5 and Karhu. Which, in principle, is enough to identify 98% of the problems. The remaining 2% in terms of using a computer (games) is not important for me. For calculations and rendering, I use a system on amd 2950x with a memory of 2133 in nominal value.

My daily driver is currently 5.1GHz---4.7Ghz-cache---1.46Vcore(1.32 load)---LLC5---1.37SA---1.33IO---1.5VDIMM---4000Mhz-15-16-36-2T

My chip is SP78, but I think the IMC isn't very good. I had cache up to 48x but needed to bump SA/IO up higher. I have a 2x16GB b-die kit I'm going to throw in and see how far I can push it next.

What was your VCore in BIOS? R20 score is a little low. 5.3GHz should easily reach 6900+

Only 4700 ring and a bit slow memory. That is why the score is a bit "low"

5.3GHz core, 5000 ring and 4200 16-16-34 memory was 6948.

ring 4800 and slow memory (4000c16) - 4x8gb memory is slower than 2x8gb. If my memory worked for 4400-4600, you would be right.
Unfortunately, there is no reliability with memory 4x8 above 4100с17
