Thank you!!
I will def give this a try.

BTW: is 1.45v a safe voltage for 24/7 usage ?
I know that its possible to go beyond that voltage but honestly im fine with 3600mhz and tight timings.

Regarding the SoC, should i keep this on AUTO or manually put it around 1.1v?
I saw that AUTO can become a issue with higher frequency 4000 +mhz.

Try 1.1v manual, it may work fine with lower than that. Check up on VDDG IOD, CCD and VDDP voltage, those should be max 1.05, 1.00 and 0.9. Some motherboards runs VDDP at 1.1v which is way too high.

 

[Ohnoitzbryan]

I checked within RM if the values are in range. Seems to be fine even tho i use AUTO settings on most values within my BIOS.

Lower your RFC Rest looks good.

 

[mstenholm]

So now you just need to set 1.1V and 1.45V and test. Yes it is safe for b-dies. People run them at +1.5V and some are even 1.45V XMP.

 

[Ohnoitzbryan]

Really appreciate the assistance!

Any recommendation for the RFC values ?

I changed the SoC from AUTO to the 1.1v manually to be on the safe side. RAM is set to 1.45v and i ran OCCT for a short time earlier today (1hour).

Temperature wise in OCCT it can get quiet warm ( 60C ) , Corsair recommends to think about active cooling at around 70C and the modules are rated up to 90C (according to their response via mail)

During normal usage (Browsing,Gaming,cinebench) they seem to be in the low 40s.

@Taraquin wanted to say thank you again for your assistance!

I lowered the RFC values, gonna run stability test for a few hours.

 

[Cowboystrekk]

240 on RFC may work, but 256 is quite good already The next room for improvement is trying to get it working with GDM off or trying higher speeds. Maybe 3800 can work?

Bad news, 2nd run of OCCT gave 1 Error after 50 minutes.

Try setting ram voltage 0.01v higher.

 

[Ohnoitzbryan]

ill give it a shot.
Curently running another test with my old frequency of 3400mhz @ 1.38v which ive used in the past but i kept the tight timings.

Gonna see if this runs stable, then im gonna try what you mentioned and go back to the 3600mhz @1.46v.

Would have been too sweet if it would have worked flawless on the first attempt.

1.46v has been stable for 90 minutes so far within OCCT, ill have to wait and see if it stays this way over a longer period of time.

Ryzen scales good up to 3800. You can basically run identical timings except CL, RCDRD, RP, RAS, RC and RFC which must by increased if speed goes up.

Generally
3400cl14 equals 3600cl15 and 3800cl16 in latency, but bandwith is higher on higher speed so gamingperformance increases. For every 200MHz increase you must raise the 3 first timings by 1, RAS/RC by 2 and RFC by 15-30.

I tested the system for 2 more hours and it has been stable so far, also tried some gaming afterwards.

Wanted to give 3800mhz a try but my PC wouldnt keep the settings, it turned off and restarted twice before reverting to default settings.

You can try 3800/1900, soc 1.15v, 1.05v iod
CL 16
RCD 16
RP 16
RAS 32
RC 48
RFC 280
Keep rest as is.

Nah, nothing has changed. Most people top out at 1800-1900, some can do 2K, some a little more.. but by the looks of things nothing has changed. Maybe with AM5.. not going to hold my breath though as I will probably make my way back to Intel around that time.. we’ll see.

I appreciate it, it must have been the voltage on the iod.
I was able to boot and been running OCCT again for the last 15 minutes.

Im having a question btw.. I checked within AIDA64, my Bandwith increased more but my latency didnt get affected at all in a negative way, its still below 60ns even tho CL was changed from 14 to 16.
I always thought that especially CL has the highest impact on latency ?

Aida scales latency with ram speed. What I would do next is try to disable gdm and run 1t, run stability test after disabling gdm. If unstable try setting DrvStr to 30 20 24 24, 40 20 24 24 or 40 20 30 24. If that don't work try gdm 2t. Next is trying 15 15 16 15 ras 30 rc 45, cwl 14. If that works try 15 15 15 15, ras/rc/cwl same. Next then is rfc 270, 260, 250 etc. Gdm makes cl and cwl run even numbers, cl14 at 3800 takes a lot if voltage and cooling so I recommend cl15 first.

Hello again!

i was not able to boot the machine with GDM off + 1T , i tried it will all the DrvStr combinations provided.

I put DrvStr back on AUTO turned GDM off and set 2T.

I skipped the 15 15 16 15 timings and instantly went for a test with 15 15 15 15.

OCCT ran for around 90 minutes without errors.

Looks very good, latency is a bit high, many background prosesses? Try aida in safemode, see how that goes

I dont have much running in the background.

Argus Monitor for Fan Control
DisplayCal
MSI AB + RTSS
SoundBlasterCommand

But yeah latency actually was much lower in safe mode.

Is it normal that it doesnt show all the information ?

Check msconfig for what processes that boots. For instance, epic games, antivirus, steam etc can eat some resources. For me I get avg 51ns in safemode and avg 51.7ns i win.

Lowest i could achieve was 55.0ns within WIN, all tasks killed and i actually found a few processes which were in autostart which are not even on the machine anymore. "java updater" for example or CCX by Adobe.
Disabled those and restarted but the lowest i got was 55.0ns still.

Also found AMD services which i didnt know exist. Probably has to do with the GPU, in case you OC it will report the issue and revert back to default settings.

Maybe there is also a difference in Windows 10 versions? Currently using pro.

55 is good Safe mode will always be faster, I have disabled all I can.

Just wanted to say thank you again for helping me optimize my RAM kit !!

Hope it stays stable, will keep it like this for a while now and then either try to dial a bit back on the 1.46v or lower the RFC values.

Really appreciate your help and hope you have a amazing weekend ahead

EDIT:
@Taraquin
Sorry for the ping but i ran into some issues yesterday in the evening.
Since OCCT only runs for max 1hr without subscription i gave Karhu Ram tester a try.

On my first run i got a error after 80minutes, i went into the BIOS and disabled my PBO/CO just to make sure its not the negativ curve offset.
I ran it a 2nd time and after around 2 hours i got another error.
Went to BIOS again and changed the ClkDrvStr to "40"
I ran a test over night and those are my results now.

Would you say its most likely stable now?
Can i keep the DrvStr like this or should i lower it if possible?

 

[Cowboystrekk]

May be more stable now, mlst important is if it's gamingstable
