Hi folks, I've searched the forum but can't find an answer to this (I've looked elsewhere as well but getting nadda).

I've recently upgraded my very old 13 year system (intel i5 750) to a nice shiny AMD 5600X and Asus B550-F Gaming motherboard. For the ram I chose Corsair Vengeance RGB Pro (2x8GB) 3600MHz (Nanya chips) kit and purchased 2 of them to give me 32GB of ram.
Now the issue comes when I install all for Dimms. The system becomes very unstable, BSOD, random restarts and files being corrupted. Someone suggested it could be the ProcODT settings, which I played with but it made very little difference.
Things I've tried:
I've tried both sets of ram (16GB) by themselves and they are stable.
Updated the bios.
Reset the bios.
Tried XMP off.

What else can I try before I give up and replace with a 32GB kit??
 
Hey Brizzles,

I enabled XMP and increased the VDIMM voltage to 1.4.
I ran Memtest86 to see if it was stable and on test 8 i started to get errors. Ran again with just 2 dimms and it runs fine.
 
So I've spent this this morning changing the SOC voltages from the bios original 1.1000mv down to 0.9500 in small increments. I even tried up to 1.1250 and still getting errors in memtest86 on test 8.
1.1000 gave the best results out of all the tests I ran.
 
Thanks for the help Brizzles, I'd kinda given up and thought about getting a 32GB set and cutting my losses on the ones I have but thought I'd at least give it another shot before I do that.
Gone are the days of DDR2 when a few tweaks could give decent overclocks and the ram was less finicky about optimised matching dimms. If I'd kept up with things I'd probably go down the rabbit hole but i haven't and my partner uses the system for editing video's so it needs to be running and stable, not me messing around with settings that could potentially break the pc.
 
If I use 1 stick or 2, either SPD or XMP I get no errors, only when 4 sticks are used. I've checked this on both sets.

I did have a look on the Asus site for recommended memory and although I copied the ram I wanted from there to Google to find vendors I've ended up with ram not on that list. Lesson there is to double check in future.
 
But surely the list of recommended ram on the Asus site would be the same as AMD's list. I was under the impression that not all memory works well with AMD especially with regards to the infinity cache. Is this wrong?
 
On the board I have you need to populate the ram slots furthest from the cpu (A2 and B2), putting ram in just A1 and/or B1 flags up a ram issue but this is noted in the manual as well, so it's a known issue/thing
