AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

[superleeds27]

So after ages of stability my ram has started throwing up errors, Firefox crashes, games crashing. The lot.
I think I fixed it by lowering the ram speed to 3400 from 3600 but it makes me sad to do so.
Any reason this has happened? I haven't touched it for ages only updated the bios and chipset recently

Could be a change in the BIOS I guess?

Bump the voltages slightly?

I tried the volts up and down and made the timings slacker, still produced errors fast. It's the f6b bios, it's that a thing that the bios made my previously stable ram lose its marbles?

If you haven't done any update (BIOS and Agesa), then it depends on the voltages you were running.

Could be degradation on the memory controller or the sticks. Looks like you have b-die which is fine for 1.5v daily so if you're below that might be the IMC.

Show us the profile you used please We might be able to help.

I can tell you of the top of my head that it was 3200 cl14 8 pack ram.
Running at 3600 and 3600 IF @16,16 16,16 32, 42, 312, 16 the rest of the timing at auto, t1 at 1.45v
I can post the rest when I'm home
I tried 48 and 34 and 414 to slacken them, I tried 1.48v and 1.42v, andd always error.
Lowered to 3400 ram and infinity together and seems okay now.

Have you not had quite a bit of bother with this ram and were potentially going to RMA or am I confusing you with someone else?

 

[Shac]

Stable settings with one bios are in no way guaranteed to be stable with a change of bios.
Be prepared to dump what you thought was good and start from scratch with a different bios.

I think so too, I'm doing that now, resetting everything to default and starting again

Yep found the post by 'Gigabyte Matthew'

Q: XMP doesn't work!
A: Make sure you are:

• Using slot A2/B2 - From CPU skip a slot, RAM, skip a slot, RAM. I cannot emphasize this enough. If you are helping someone T/S a problem this should be your first question.
• You are using the latest BIOS.
• For debugging RAM please keep everything else default.
• If the above don't help post your RAM kit and any steps you have tried to fix the problem.

Thanks a lot for pointing this out to me. Funny thing is that is how I had it in my 4770K system I believe, but it has been so long that I completely forgot why or even that it was a thing.

When I get the time to go back on the pc later on today I will certainly change them over and try xmp once again, touch wood (touches head) it solves my issue!

How are you getting along with solving the spiking issue? Have you tried messing about in Ryzen master? I was happy to see setting all cores to 4200 and locking vcore to not go above 1.25v worked and passed cinebench and run cooler doing it. On default it spike to 1.42v a lot which seems excessive to me!

Lots a tweaking to do to see what this chip can do. Hopefully I got lucky like I did with my 4770K which has been running 4.7GHz for me for from the time I purchased it.

 

[michty_me]

No not I

Apologies, Obviously my confusion. There was someone with the same RAM that was having big problems getting it stable.

Me?

Though I only started last night so maybe someone else that you are talking about.

We have the same ram? And both just started having problems at the same time?
Did you update bios, Windowsor chipset or anything recently. Maybe we have the same problem

You do know if you manually tune the ram on Ryzen you have not only use subtimings but set things like Gates, resistors, SOC, VDDP etc.
And all in perfect balance

Thats why I want the screenshots form the DRAM Calculator you are basing your settings (it has a screenshot button to save image), in addition to the other application to show us your factory ram config.

Nope, just had a look at your RAM. Mine is a poorly 16GB Corsair 3200MHz CL16

Did not think it was worth spending more than £75 on RAM as this will not be my long term system and is destined to go into my partners PC as soon as AM5 platform is released in 2021

Agreed. I tried doing it manually the normal way 2 times yesterday and it did not save at all and just went back to defaults. Still not changed my RAM into the correct slots, going to do that in a bit and see XMP works. If no luck with that will be getting that screen shot for you and requesting your help Panos

Hey Panos, I wanted to ask. Been playing with Ryzen Master and have made 3 profiles so far which all pass the default 30 second stability test on Ryzen Master and get trhough CineBench without issues.

Profile 1: 4GHz on all cores at 1.2v.
Profile 2: 4.2GHz on all cores 1.25v.
Profile 3 4.3GHz on all cores 1.3v.

Each one starting from 1 to 3 naturally get hotter and get a higher score on CineBench so it is working. Only question is how stable are they? What tests do you guys run to test stabilty on Zen 2? On my 4770K it used to be handbrake. If it passed that then you was golden. Handbrake would find any instability that other programs or games would not for me.

Also I noticed, Ryzen Master seems to prefer all cores at the same speed. If I do say 4.4GHz on C6 and 3.8GHz on all the rest of the cores then two of those cores would be stuck at around 3.52GHz. This is also true for many other combinations I tried. You end up with a lower score on things like CineBench when going down this route. Going to experiment a lot more with this later as I would not mind having one core at 4.4 or 4.5GHz and rest at 3.6GHz for my daily use. What have your finding been?

Show me a screenshot of your Ryzen master. It should look like this (minus the numbers)
Pay attention to the symbols next to CCX and CCD (added the correct image)

That bellow is per core overclock done correctly

Here you go:

 

[Panos]

Here you go:

Then you need to set the number accordingly. One by one per core, but not all cores the same highest speed, as they will be unstable.
Also raise the voltage. 1.35 min - 1.4ish is OK. 1.45 with good cooling.

Is that for more stabilty? As I find more volts (obviously) leads to more heat when spiking. Like I did the test with the steam downloading a game just now when everything on 4Ghz at 1.2v and now it is around 50C max instead of the default profile (used about 1.42v) it going to 65C with some spike which caused the fan to ramp up.

Also, you never answered this question: What tests do you run to test stability on Zen 2?

After a quick run the usual crap (like Cinebench), surprisingly World of Tanks. Anything that's missed by 3D Mark etc is always been picked up by it crashing. And I dont mean the benchmark but actually play few battles
I do not touch Prime as is completely crap and archaic method.
