New RAM wont boot

AshB1989 · 24 Dec 2020 at 13:56

Just upgraded to Vengeance Pro 3600 32gb and now it wont boot.

I have a B550 Mortar board and Ryzen 5 5600x CPU.

When it originally booted it went to BIOS and I just saved and exited, now I don't get anything. No display. Nothing. I cannot seem to get into BIOS now.

Any help would be massively appreciated.

Update your bios to latest version using the flashback tool

How do I do that? I cannot get anything up on my screen - it appears to be working yet cannot see a thing.

Get the file and put it onto a usb stick then use the button on the back of your motherboard (providing you have one) look in your manual for instructions.

Only have the one computer, bud

Edit: keyboard isnt recognised/turning on, which could be why it isnt entering bios

Reset BIOS with the jumper on the board?

I'm sorry, but how do I do that? Never had to do it before

AshB1989 · 24 Dec 2020 at 14:44

Brilliant, thank you. Would the jumper cap be supplied with it?

AshB1989 · 24 Dec 2020 at 14:56

Did exactly as suggested, but made no difference.

Is there any way to know it has reset the CMOS?

AshB1989 · 24 Dec 2020 at 15:08

Okay, so I messed around with the USB (keyboard wasnt working) and I can now get back into the BIOS - thank god (and Vader).

Now I remember reading something about the A-XMP profile, which was disabled. I am sure I remember reading that I should enable it, could anybody advise on this please.

AshB1989 · 24 Dec 2020 at 15:19

So I enabled it, saved and exit now I'm back to square one - wont boot.

Try manually setting it to 2933 at 1.35v?

I am a complete novice when it comes to ram. How would I do this? Advanced setting in BIOS?

AshB1989 · 24 Dec 2020 at 15:37

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

Okay - I'm up and running. Does this seem correct? I remember trying to figure something out before with ram and had no idea.

AshB1989 · 24 Dec 2020 at 15:54

Do these figures appear to be correct?

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

AshB1989 · 24 Dec 2020 at 16:12

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

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.

@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.
