Guys!
Looks like the new Ryzen 4000 Vermeer will be able to deal with faster RAM like 4000MHz.
Building a Ryzen 3000 now and waiting for the new CPUs to arrive, but what about RAM?
What would be better, Crucial 2x32 3600MHz or Crucial 4x16 4000MHz ?
The 4x16 4000MHz modules are the great Micron E-die 8gbt chips and the 2x32 3600MHz
are Micron new 16gbt B-die, the old Micron 8gbt B-die are not much good...
Thanks!!

Here you go, not 3666 but 3600 CL16, 1.4V (which translates to about 1.43V on a GB board):

Ballistix Sport LT Overclocking

@MegaPinches these are the slightly updated ones which I think should work with most E-die kits & CPUs, should get you ~66ns in AIDA64 on a 2x SR kit: tCL 16, tRCD(RD) 20, tRCD(WR) 20, tRP 16, tRAS 38, tRC 58 tRRDS 4, tRRDL, 6, tFAW 16, tWTRS 4, tWTRL 12, tWR 16, tRDRD SCL 4, tWRWR SCL 4, tRFC...

I have those timings and seems to be it's stable at 3666MHz CL16 @ 1.43v.

What's causing cracking sounds while gaming for example PUBG when ram is overclocked to 3733MHz 1:1 1867MHz, while at 3666MHz 1:1 1833 MHz there's not such an issue.

Google say's that may be VDDG Voltage but i can't change it from auto 0.950v if i will go higher or lower system will crash ?

Tried really a lot of things in bios nothing seems to help.

MB - ASRock B550M Pro4
Ram - Crucial Ballistix 3600 CL16 2x8 (E-Die)

 

[Pictus]

It may be the VDDG IOD, here for 3733 I have like this

 

[AlwaysHope]

I tried dram calculator 1.7.3 it will not even post with these timings and voltages at 3666MHz fast preset. ASRock motherboard doesn't like new versions.

I've had that happen with 1.7.3
An issue to keep in mind is that bios & chipset driver updates have taken place since calc was updated.
So in effect, the calc is merely a guide, not a must do.
It recommends CL14 for my sticks but the system never could boot with that. CL16 fixed it.

I'm curios of this as well, but hesitant to upgrade unless it can be shown that early bios supporting them do not have too many "quirks" or faults in them.

16Gb Rev.B could be worse, but like all the other currently available 16Gb chips, it can't hold a candle to 8Gb ICs like B-die and Rev.E. tCL seems to be mediocre, voltage requirements don't seem to any better than other ICs, and tRCD and tRP are downright horrid. Pretty sure Rev.B does not even scale tCL with voltage even beyond just 1.4V either, but don't quote me on that; if true, that places Rev.B firmly in the low end category.

On the other hand, while Rev.E overclocks excellently on MT/s, 4 DIMM dual rank is undoubtedly a significant penalty to maximum achievable frequency on the vast majority of boards. But achievable max MT/s is still highly dependent on the DRAM voltage you're willing to run, and doesn't change the fact that Rev.E does better than Rev.B on timings and is generally just a better IC.

If you really need 64GB, I suppose it highly depends on whether you'll be just using your computer, or if you'll spend most days tinkering with your RAM. If the latter's the case, I don't think you won't be getting very far with any 16Gb IC. I suspect we'll only get a solution to this balancing act between 32GB-per-stick density and actual overclocking performance when DDR5 rolls around. Hell, we're in 2020, and mid-high end 8Gb ICs like DJR and Rev.E still can't match Skylake/X99 era 4Gb E-die on primary timings and therefore latency; as hard as Samsung has tried, 8Gb B-die is still king. We've only really been making strides on density, consistency, and MT/s overclockability.

I'm pretty happy with my ram, $170 - 2x16gb (32 total) in dual channel at 3600 cas 14-14-14-36 @ 1.43v and timings tighten with the calculator. I get 66ns

it's not the greatest ram in the world, but honestly, the gains are so small after that 3600 cas 14 baseline, its not worth it to me to go back to 8gb sticks.

It may be the VDDG IOD, here for 3733 I have like this

So turns out that i actually can select VDDG IOD to 1.050v and it works helps maybe slightly but still there are cracking noise while in 3733 1:1 1867 mode.

I do not understand why i cannot select VDDG CCD voltage to 1.050v as dram calculator 1.7.3 recomends ?

And the wreidest part is that at ram stock setings (all on auto) i can run VDDG CCD voltage at 1.050v and it works ? And this is only time when i get this voltage to work at 1050v. So seems to be that some of recomended settings from dram calculator 1.7.3 is blocking this voltage to work ?

RAM overclocking is such a time eater.

User's with ASRock B550/X570 and Micron E-Die should notice something similar.

 

[Pictus]

Yes, it is...
Sadly I am not a memory specialist to proper guide you, but
did you placed the RAM sticks in the right slots?

Did you updated the BIOS and after the update clear the CMOS?

Disabled Spread Spectrum?

 

[AlwaysHope]

Spread Spectrum can be necessary, each system will vary with its stability option. Best to experiment with the setup before disabling it. I have successful RAM overclocks with it set to auto.

If you want to set the VDDG CCD voltage to 1.05v and above, the SOC voltage has to be higher than 1.05v, since the VDDG CCD voltage is derived from it.

Hey guys, can someone tell me what type of memory do i have?

Thanks you!

If you mean what die they have, it appears to be CJR.

Yeah sorry I'm new to memory tuning.. Having issues with my kit sometimes didnt boot sometines boot perfectly..
I'm trying like crazy!
Thanks!

Would anyone know why I keep.getting random reboots with my ram? It's the gskill 3800 c14 trident z neo kit.

Occasionally the pc will reboot with no bsod and end upon the lockscreen. Event viewer shows kernal power error 41. Thanks

Are you sure it's RAM? What are your other settings? Could also be FCLK instability.

i have cpu at 4.3ghz 1.32v pbo disabled, ryzen 3900x

 

[Tomorrow]

Are you running XMP or custom timings and settings suggested by the calculator? It could be that one of those settings is causing problems.
The calculator sometimes suggests some pretty weird things.

I'm using xmp and only setting the speed and FCLK so I get 1:1

I'm finding it very difficult to pinpoint the fault

This sound like fclk/infinity fabric, I can say 99% sure that this is not ram-related as I have the exact same issue at 3800/1900. I suppose you run 1900 IF? There are 2 possible solutions: Try increase SOC-voltage to 1.125-1.15V and try VDDG IOD 1.075V-1.1V, there must be 50mv between them. If that does not work your I/O-die is not binned for 1900 so reduce to 3733/1866 which for 90% is stable and tweak subs instead. I can run 3800/1900 stable at 1.175V and 1.125V VDDG IOD, but this is above my comfort sone so I run 3733 instead which is 100% at 1.07V soc and 0.95V VDDG IOD. If doing 1900 requires a much higher voltage I would drop it as it could lead to other issues running SOC and VDDG that high.

Can’t you see in EventViewer whats the description for that error 41?

It just says pc lost power unexpectedly, I did noticed last night I could hear crackling when playing music whilst running randomx. Iv since lowered the frequency to 3666 and I'll see if it's stable. Problem is with xmp enable it fails memtest5 for some strange reason, even when I run at 3600mhz

First time user of DRAM Calculator for Ryzen. I have version 1.7.3. I'm an OC noob. I would really appreciate some help and advice from the experts here.

The DRAM is CMK32GX4M2B3200C16, which I ordered because it's on the support list for the MB. It's XMP3200 certified. When I enable the XMP profile, the system will not boot or even POST. The DRAM is running at 2133.

According to Thaiphoon Burner, the DRAM manufacturer is Nanya Technology, which is not supported by DRAM Calculator for Ryzen. There is a reference to Micro Technology, reported by Thaiphoon Burner. Should I set Memory Type to Micron A-die? Also, should I set the DRAM PCB revision A0/B0, based on the Reference Raw Card: B0, reported by Thaiphoon Burner?

I would appreciate suggestions to see if I can get this DRAM running faster. Also wondering if I should return it and exchange it for something else. Thanks in advance.

First thing to try if you're using xmp profile is manually set the voltage to what is on the ram sticker, sometimes xmp tries to use much less than you need. If your mobo boosts the voltage set it lower until you get it as close as you can to the sticker value. Mine is 1.45 in the picture below you can see how my mobo boosts the value I set. Yours is 2 values listed on corsairs own website as 1.2v and 1.35v so idfk I hear corsair isn't the greatest ram.

Nanya ram is micron I think so setting to micron should work. Also yes set to what thaiphoon burner lists. Best option is to return and get samsung b-die, I use Patriot Viper ram which is samsung b-die and not overpriced like most. I would recommend getting a faster kit than you need, like 3800mhz or more just in case you can clock it that high or somewhere in between.

 

[purecain]

oobymach is right, you need to manually set the Ram voltage to 1.40-1.45v in the bios.

I just read about your ram, if this doesn't work try a different set, something with E-die or older B-Die like previously recommended. Good luck!
