Try up to 1.55V VDIMM. And raise VSoC to 1.15V temporarily to rule that out as a probable cause.

 

Yep tried both no success, I think I'll try another aproach.
I can boot and pass the whole 1:45h of TM5 (anta@extreme) in 3866 1:1 FLCK
But I'm having wheas alerts in HWInfo (no BSOD) something like cpu interconect etc, trie with SOC in 1,15 no luck

 

run 16-20-20 and try running your tFAW at 20. This should help remove the need for extra voltage.

tRRDL and tRRDS could be a smidge looser at 6 and 4 rather than matched 4/4

Not an expert at all, but just spitballing what has helped me in the past. My X99 rigs were always super finicky with ram, and these settings helped calm them down a bit. Clearly worlds apart in architecture, but "relieving stress" of the memory controller is kinda universal to helping to push higher clock speeds!

 

Tried that, no luck but thanks anyway

 

I'm not familiar with e die at all. But I can tell you some types of ram do not scale speed with voltage. Some run slower. Some just refuse to work at all with much any adjustment. b die is VERY forgiving. I'd recommend reading up on e die and see what it is capable of and what it may or may not like.

 

Hmm. what are some of your voltages? specifically SoC, vcore, 1.8v, etc...?

Sometimes, ram voltage itself is a hinderance, rather than a helper.



reddit has a group that focuses on Micron E die, might be worth a check to see if there are any specific settings that the memory hates for stability, causing odd issues.

 

I'll look into this group, never heard about thanks
About voltages:

 

I did see a SoC votlage of about 1.08. This may need a bump to 1.125 or thereabouts to enable the use of higher speed ram. Dont crank the snot out of this votlage and leave it, but you can toss 1.15 volts at it, and if everything becomes stable, take some time to drop this down a little. 1.125 is reasonable, but a temporary jump to 1.15 will let you know if it helps right away.

 

I just noticed that you are on CR1 (1T). Try seeing what you can do on 2T.
Also, loosen tRAS. 28 is extremely tight.

 

I using Micron Rev-E Corsair 4x8gb 3600cl18 sticks @ 3800/1900c
You can give these settings ago. Only way for me to run with GDM Off 1T was to use 120Ohm on CLKDRVSTR. With GDM on I use 24 Ohm. These settings are stable for me.
In digi+ I am running extreme full phase mode and max current settings for all. Freq switching left to auto.
I am running Vdimm @ 1.415
VSOC 1.125
VDPP 1.05
CCD 1.05
IOD 1.05

 

tRDRDSCL & tWRWRSCL @ 2-2 usually requires voltage in the 1.550V and more to work.

I have some Micron Rev.E D9VPP from the early Micron rev.E batches.

My kits can take up-to 1.700V if you have some extra cooling. 24/7. Just keep them cool with some cooling.
Mainly to push lower tCL, tCL13 possible @ 3800Mhz with such a voltage on my kits.

tRCDRD depends on the bin of the individual kits. You get what you get your kits can manage.

 

Thanks will try that.
