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

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

Possibly not, but I just use a flat head screw driver. Just shut down the PC, I personally turn off the power on the PSU as well, touch the screw driver blade to the two metal prongs for 10 seconds, turn power back on the PSU and try powering the machine again.

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?

VaderDSL · 24 Dec 2020 at 14:57

Sadly not, it doesn't give any feedback when it's done/if it's done.

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.

Yes, you need to enable XMP or your RAM will run at 2400MHz. It SHOULD be enable and go. Make sure your board sets the memory voltage correctly (mine sometimes doesn't) at 1.35v though- I imagine it will.

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?

VaderDSL · 24 Dec 2020 at 15:27

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?

Tetras · 24 Dec 2020 at 15:28

I don't have your motherboard, but from a video I saw it is in OC settings, DRAM frequency and DRAM voltage. I'd let the board choose the timings.

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.
