Question Did I buy the wrong RAM?

Hi there all.

Just built my new rig as follows:

- Motherboard: ASUS B650 E-E
- CPU: AMD Ryzen 7 7800X3D
- GPU: ASUS Strix 4090
- PSU: Corsair RM1200i Shift

I have used the following RAM: https://www.scan.co.uk/products/64g...ominator-titanium-black-pc5-48000-6000-cas-30

Upon post, the Q-Code goes to '46', before then resetting to '15' with the RAM LED indicator ON orange.

Having then searched to troubleshoot - I can see that this RAM is not listed on the Asus memory support page: https://rog.asus.com/motherboards/rog-strix/rog-strix-b650e-e-gaming-wifi-model/helpdesk_qvl_memory/

Does this mean that this RAM will categorically not work with this motherboard - or is there a work around?

Many thanks for your time.

Just because its not listed in the QVL, doesn't always mean its not compatible, as there is a limit to how much they can test and guarantee working.

The RAM should work though, so i suggest the following troubleshooting steps.

First, try booting with just one stick of RAM. Next, if it boots, try with the other RAM alone as well. If all goes well, change the slot and try different combinations to check if you can corner out one RAM stick or a slot that seems to not work.

That RAM should work fine.
Are you installing them in the second and last RAM slots (from the CPU)?
Note that RAM training can take a while, especially if it's an old (or original) BIOS. Reseat the RAM in the proper slots, power it on, and let it sit at least 3+ mins.

Also wouldn't hurt to reset the BIOS.

Edit - If you can't get it going, maybe try the BIOS flashback to update the BIOS to the latest without the CPU installed.

Seems to be happy with the RAM now. Perhaps a seating issue! I'm at BIOS now and installing Windows.

Thankyou for all your help 😉 @alceryes was the key - let it sit and learn for a few minutes!

Thanks all.
 
Just as a further query..

I initially purchased 2x32GB of the RAM, and before building added another 2x32GB to the build. Corsair did not offer a 4x32GB option.

The RAM speed is showing as 3200 in the BIOS. Turning DOCP on and selecting the RAM speed seems to force it into a Q-Code '15' where it will hold for a while before kicking me back to BIOS. From what I can gather - this is due to the mis-matched pair?

Whats the best way to try and achieve parity and near matched speeds? DOCP doesn't seem to be an option.

What do you need 4X32GB for? The problem with DDR5 is, adding any more than 2 RAM modules will cause it to default to a much slower speed. You have 6,000MT/s RAM but you'll be stuck at that 3,200 while you have all 4 installed. Unless you really need more than 64GB, I would remove a set to get the much higher speed.
 
Hand on heart - purely aesthetics! The two missing sticks on my old PC bugged the crap out of me for years.

Is there a potential use-case in the future for the 4 sticks or is it best to return?
