System hangs when XMP enabled at 3200

I've got this memory 2 x 8GB sticks:
https://www.overclockers.co.uk/cors...hannel-kit-black-cmk16gx4m2b32-my-456-cs.html

Thats with a 5600X and MSI B550 Tomahawk with EVGA 1060 6GB SC.



Which works fine at stock 2133 speed, but if I enable XMP at 3200 it crashes after about a couple of hours. The mouse keeps working, but all windows and apps arent responsive.

Looking at the shop, this one says Ryzen Optimised:

But surely the other RAM shouldnt cause it to crash?
 
The one from October that allows 5000 series CPU, but not the latest beta version.
It doesnt say anything about RAM on its release notes so I'm not tempted at the moment.
 
Yep - the 2nd and 4th slots. The non-beta one (whilst 4th nov on the website) has a build date of late october - thats the one I have. Reading more about this on Reddit and Corsair forums, it looks like Corsair have xmp issues with Ryzen more than most - which may explain why there is that "Ryzen optmised" version I linked to above. I would hope that it doesnt mean I cant get mine working though.

Thing is though, the info you've posted above shows you have Samsung B-Die which normally is the best for Ryzen systems, it's the Hynix from Corsair that normally causes issues.

Try with just one stick, then the other, also try memtest on them to see if that picks up any errors?

Also try and remove them completely, and reseat them.
 
I'll try memtest out and see how it goes - thanks.
I've just flipped XMP back on and I'll see how I go.

I think its the RAM, as when I put it back to stock speed, I havent had a single hang. If I get another hang now I'm back on XMP I'm sure its the RAM.
I'm also wondering what exactly the "Ryzen optmised" version of this RAM I linked to above does - is it a whole separate product from Corsair?

Is that taiphoon burner screenshot yours?

Normally the kit you have isn't Samsung B-Die, it's Hynix, which is known to have issues with Ryzen, that's why they released the AMD optimised version, which usually has slower & even numbered CAS ratings, but as I said you've been lucky enough to get the Samsung stuff.

Run memtest, that'll give you an idea. If it fails, run the test on each stick individually to find the culprit.
 
Yes, the Taiphoon Burner screenshot is from my RAM.
Memtest is still running, here is a screenshot.



After that I'll see how long it lasts in windows at xmp 3200.

It sounds like I have good RAM from what you say, just frustrating it doesnt seem to be stable at 3200.
Thanks for all your help so far.
 
Here are the memtest results, it seems ok.



I'll keep it running overnight on xmp 3200 with a few downloads going and see what happens.

Tried Ryzen DRAM calculator and inputting those values into Bios rather than using XMP?

I started to take a look at that but got a bit overwhelmed with quite how many changes I should (or shouldnt) be changing.
I think the changes I should make are these:


but after delving into the bios, the list of settings seems never ending! I can see why people like XMP!
 
How do those timings compare to your XMP timings and freq? How about the voltages in the top right?

I had a lot of success with that calc, I have 32gb of b-die (patriot viper) running nice and stable at 3600 CL14... it does require a bit of time finding your way around the bios settings though I agree.
 
Are you getting event 18/19 WHEA errors in event viewer?

Either way I'd still recomend going with the latest agesa 1.1.9.0 bios as it brings stability improvements.

I would agree with this - on my x570 unify/ 5900x the official bios was causing all sorts of issues when OCing ram. Things have improved significantly since I installed beta BIOS and even more so since the beta 1.1.9.0

Is that this data?
 
Yeah, so even on safe preset the DRAM calc is suggesting you can tighten it up over the XMP profile.

No problem running even the higher end of that voltage recommendation with B-die which may help with stability.

Worth spending some time in the BIOS to figure out where all the settings go imo but update to the latest one first as it's a bit of a faff to go back and change them again each time you update the BIOS. Once you've arrived at a stable set of parameters take some screenshots in bios to have to hand whenever you need to update.

I recommend Karhu ram test - much more efficient than memtest, a 60 minute run will have over a 98% detection rate... It's pretty cheap RAM Test - Karhu Software
