weird ryzen unstable memory oc needs enlightenment

[clutchmaster]

having a weird symptom of instability and would like to get some enlightenment
ryzen 5 3600

asus crosshair 7 hero (bios:4301)

g.skill flareX 3200 CL14 (samsung B-die)

symptom-- system hangs with some function witch also hangs (ie  right click menus/ open programs) forcing a reset button press seems to only occur with 50+ chrome tabs when switching or closing a tab or when im watching amazon prime video when skipping ahead or without skipping
but so far never happens while gaming 6+ hours of escape from tarkov which shows upto 14gb of total system allocation in rivatuner

also never get any errors after running memtest64 and dram calculators MEMBENCH for 12+ hours
edit: i never get a bsod and i have cpu oc disabled

 

3600mhz/3533mhz(fclk 1:1 mode) both crash system

soc voltage(LLC: LVL 4) 1.118v/1.112v
Dram  3600mhz= 1.44v/3533mhz= 1.42v
VDDG ccd =1.00v

VDDG iod =1.00v

Well you have an unstable oc when more load is put on the ram so basically go back to stock or a lower frequency. Not all ram ocs well.

[narrdarr]

that voltage is so high

maybe 1.375 16 18 18 18 36 to 42

Most probably this is not a Ram problem. check event viewer for the errors.

Totally unnecessary, but if it can finish it, i think the memory are fine.

 

Bdie can do a lot higher than 3600.

its samsung B die it scales very well with voltage it hangs under none loads light loads based on what i found from prime video hanging the system is related to memory corruption

if only i had another ssd to fresh install windows on but cant since im dual booting a test os and my main and the test os has a paid version of thaiphoon
do you know of any sub timings related to memory clears
and whenever the system hangs event viewer cant seem to log the event only errors a dns client service for system and coolermaster masterplus renew.exe

[clutchmaster]

also it only hangs after either with those apps open for hours on end or when i return from being afk for 30 minutes... and get 30 minutes or more into whatever im doing youtube/prime video or even hours into it.  but never while gaming and command rate seems to have no affect on this

i use 1usmus dram calculators memtest because it runs the memory much hotter then memtest64 upto 20 degrees F hotter highest temp recorded is 132F and the second stick only 130F

The best thing I've found for a fast stability test is y-cruncher, throws errors where I can run hcimemtest or p95 (large) for long enough to be considered stable.

Here's a guide on OCing ram. https://github.com/integralfx/MemTestHelper/blob/master/DDR4 OC Guide.md

You're running OC over the extreme memory profile.....

 

Loosen tRas to 36. Maybe trfc higher also.. even in the 700s if that's where you find stability. TRc you can try and loosen a little too..

 

Don't have my rig up and running to give you more timings to try.. sorry for that.

That may or may not help.. probably a little of both

i can actually tighten TRFC below 400 and the symptom doesnt get any worse nor improves im just running it this high so i can mess with it
also idk how tras could help since its only the total time of trcd and trp

From what I've noticed, the AMD systems like trc looser at higher speeds....

 

And of course some memory PCB does better on a 2T command rate like A2 memory PCB which is what my Bdies are running. So at high frequencies some 400+ mhz beyond where you're at (on an Intel system) 2TCR is the way to go.

 

Tweaking memory can literally take weeks of trial and error. So all I can really recommend is try and test.

figured it out it was either trdwr / trc / trtp finally achieved 3733mhz

 

Dram  3733mhz= 1.40v

I mean they're saying you need to start all over...

 

Also personal opinion idk why your voltage is that high... my ram is at 1.35v, oc'd from 3200 to 3600, and thats incidentally exactly the voltage it would run at with xmp, i have xmp disabled (however)

 

 

Did you try running xmp, is it stable and at what voltage?

Huh, so you figured something out, good. Whats the temps at?

I think my trc is comically  high... id need to check this sometime, but I kinda still think my mobo isn't fit for further  tinkering (msi b350m mortar, with dodgy bios  )

A few concessions were made to run at that speed with 1T GDM off. Were those concessions you made worth it?

In order to manually run an odd cas latency, you have no choice but to disable gear down or the board will force an even number latency and usually higher than desired set timing.

I usually set 2T gdm off with odd cas, but tighten everywhere else. I was just curious if he saw any real gains as I have not got down that route. I have a hard time with straight 1T.

Ah, excuse me, sirs,  I think my trc is kinda ok, its my trfc thats sky high?

(She approves, but she's also equally clueless as myself...  )

It's not going to make or break performance. The change of just that timing would be well under 1% of any difference.

Ah, ok, but it all adds up, right, so trc + trfc also doesnt do much then?

Just curious.

These timings can slightly lower latency together. 

 

So to really see performance "gains" you want bandwidth first (frequency) then go for lowest latency possible at that OC speed.

 

But speed first. 

[clutchmaster]

if you guys want to see if u are gaining anything performance wise download  linpack extreme trc if u can get it tighter can result in 3 gflops in performance trdwr can realy slow down ur performance so realy tighten that up trfc can gain an additional 5 - 8 gflops u can use 1usmus ryzen dram calculator to get recommendations but u will need to change ur latencys to nanoseconds with thaiphoon burner 

[clutchmaster]

figured out the instability issue turns out the system locking up was because of a failing hard drive even though the smart info says its all good 

[freeagent]

I had a short in a molex connector throw my entire system out of whack. It was to the point I set up an RMA to return my 5900X to AMD. Except I was having major issues running my 5600X as well. I inspected everything and I replaced that connection and she was back to stability and rippin. They can be sensitiff
