Question Memory issues on b450 tuf gaming plus

[Mr_3ppozz]

Hello everyone,

I am running a Asus b450 tuf gaming plus board with a ryzen 2700x..
For a good long while I ran a 16gb kit of crucial ballistix 3000mhz memory and it worked well.
Not to long ago i upgraded to a new 32gb crucial ballistix kit this one is 3200mhz

When I instal the kit separately it works fine. But I figured why not use both sets... however when I plug in both kits, the system won't boot. It won't even post. There is power to the board and the fans start turning.. the very first time I get a post error beep ( long long short short short iirc) and that's it... every time I try to reboot absolutely nothing happens, not even the post beeps.
I then have to clear the cmos to even be able to boot either of the 2 kits.
This was all strange enough but I just gave up and tried setting the docp profile on the 32gb kit...
However, the moment I enable it. The exact same problem occurs... the same post beep error... and again a reboot makes it completely dead apart from rgb lighting and turning fans...

A quick cmos clear and a reboot and it works fine but again without docp and only a single kit...

Is there anything I can try to see if I can solve this problem?
I tried using the Asus desktop software to update my bios but it says I'm up to date... and I honestly have no clue how else to update it... normally I would think a usb drive would work but either I'm completely blind and can't find it, or there is no bios update tool for my board from Asus?

I hope this is enough info and someone can help. I can provide any details needed and even make a quick video of the post problems with both kits installed...

My settings in the bios are completely default. Nothing chanced as any change makes it angry apparently

Thanks to anyone that can help
Kind regards,
Mr_3ppozz

Welcome to the forums, newcomer!

Please don't mix and match kits of ram to get a cumulative number. You should look at ram upgrades like you would with buying shoes and if you loose a shoe out of the pair. You can go to the shop to buy the shoe but the people there won't sell you one, instead you need to by a pair. That being said, there a reason why we ask to have all the sticks on your ram channels be the same - it's to maintain stability.

You should give up on mixing and matching two different ram kits on that platform. Which BIOS version are you currently on for your motherboard? Got a link to the 32GB kit you're trying to get to it's advertised speeds?

Hi Hi,

Thank you for the very fast reply

The mixing and matching of the kits was done after a chat session with a crucial support employee. They did say it should work but could not guarantee it, which is why I gave up.

The kit I'm trying to use is this one:
Crucial Ballistix 32GB Kit (2 x 16GB) DDR4-3200 Desktop Gaming Memory (Black)
BL2K16G32C16U4B

The bios version is 1804
Release date 07/29/2019 (which seems old to me)

But when I check EZupdate it says there is no need to do anything. And does not give me a option to pick a different version

If I can figure out how to add a picture to the thread I can show you the printscreen of it (via Twitter is also an option if that's allowed and works)

Thank you

here is the EZ update printscreen that says there is no need to update
