New RAM wont boot

Yeah I think I've done as suggested. Will the 2933 be slower than 3600? Should I have just bought 3000hz ram?

Well, yes it will be slower. Noticeably slower? Probably not.

Quite a few people are having memory-related issues (it's happened with every gen of Ryzen so far...). Find a setting that will run, perhaps 2933MHz, and leave it there. There will certainly be BIOS and AGESA updates in future- it's still a very new platform.
These teething troubles seem to be more commonplace now, especially on the AMD side of things.

Be worth seeing which BIOS version you're on also. The initial release of the BIOS supporting the 5000 might work, but later BIOS revisions often fix things/make things more stable.

AshB1989 · 24 Dec 2020 at 15:54

Do these figures appear to be correct?

Edit: updating to latest BIOS (V1.30 -> V1.54)

That's running at 2933, I didn't suggest it to leave it forever, just to see if it worked.

AshB1989 · 24 Dec 2020 at 16:12

Alright. Wondering if it's worth trying 3600 again now the BIOS updated?

The timings are very slow. You could probably shave those down quite a bit.
It's a c18 kit at 3600MHz, running slower than that should mean faster timings but I guess your mobo is playing it safe (your speed is correct, btw- will show as half-speed because that's how DDR is).

You could try upping the speed a notch or two at a time, maybe say 3200 and see how it goes. If that works, try 3466, rinse and repeat. Let's see if the new BIOS helps...
We need to get the MHz sorted first, timings can follow later!

My Teamgroup 3600Mhz RAM (2X8) does the exact same thing, if I use XMP profile 1 it reboots and will not power on. I then have to reset BIOS and use XMP profile 2 in the BIOS which works fine, no idea why the profiles look identical when looking in CPU Z (assuming CPU Z shows the correct details) not sure if you can choose a different XMP profile?

So I tried this, whilst setting it to 3600hz and upping the voltage to 1.35 and it appears to have worked - thank you so much. No idea why the profiles would be different in any way.

This look good?

That will do for now!

The timings can probably be improved, but yes, you're now at 3600MHz. Stuff the timings for now, that's not a biggie in the grand scheme of things.
The 22s can almost certainly all become 18s, and that Trfc is ridiculous.. but it's working and that's the main thing!

Changing the timings will involve manual entry of the values- there's a thing called Ryzen DRAM Calculator which will give you the recommended timings. This is not as tricky as it sounds, so as and when you'd like to try, myself or many others here can talk you through it.

For now, I'd say enjoy your system over Christmas...

EDIT Apology for over-use of the term 'for now' in this post.

That'd be brilliant. I'll leave that for now haha. Your help is much appreciated - thank you.

The new Ryzen ranges have all had their hiccups... my RAM won't even do the speed it used to, as I'm pretty sure I've ragged the memory controller a little too hard (2nd gen very hit'n'miss- you got a good one or you didn't...).
I'm stuck at 2933 with only 16GB now, and boy is that annoying.

These things are sent to try us.

Make sure you fit the sticks into slot A2/B2.

AshB1989 · 26 Dec 2020 at 10:52

@DoneADougalOnSofa I've just downloaded the DRAM calc and it appears to only support/recommend for zen2. I've not bothered tinkering with it as I don't want to cause more damage.

DoneADougalOnSofa · 26 Dec 2020 at 13:44

Ah, fair enough. I'll keep an eye on it, I imagine they'll update it for the new chips some time soon.
