Hey! Bit of an odd one. I had 2 x 8GB in and I've swapped them out for 2 x 16GB of the corsair vengeance (basically what they were before!)
Both 'about' and task manager are showing 16GB. This doesn't appear to be the issue where it shows 32GB but is only using 16GB I mean, it's literally only showing 16GB.
Bios is showing 2 x 16GB sat in place and I've done a mem test to confirm no issues. I've re-sat them and also made sure boot isn't limiting memory usage. I feel like I'm pulling my hair out here. Any ideas?
 
What is the motherboard and CPU being used?

What is the model number of the sticks?

Which version of Windows is being used?

Did you put them in the same slots?

Have you tried with all sticks in place, including the old?

Have you looked at msconfig?

Make sure your CPU is properly mounted - ie actually take it out and put it back in again.

Update your BIOS afterwards but I think a CPU socket pin isn’t touching properly.

The RAM is vengeance rgb pro SL. I was using basically the same before. I’m on Win 11 pro 64bit. Msconfig shows 16. No iGPU allocation.

I tried them singular and back in and in different slots. I’ve got replacement ones coming today just to see if it’s an issue with them but I can’t really see it. I’m really confused, I was just expecting plug and play like I always do with RAM :’)

PC is still a fairly new build so nothing looks out of place, all clean as a whistle in there

Doesn't matter, still try resocketing the CPU and memory.

I once build a brand new i7 930 (FCLGA1366) back in the day and nothing posted or worked at all and I was sure I got it right. Someone rebuilt it and it worked fine. Worst bit was that it was a build for the majority shareholder of the company I worked for and I told him too his face that it was faulty. I got a talking to for that.

Buying replacement RAM is fine but it's spending money when you might not need to.
 
So I’ve got a replacement and still the same issue! I’ve now removed the CPU and put it back with no changes. Both 8GB’s were in the same location and showing fine. As you can see the bios sees them both but is only reporting 16GB total. I’m so confused! https://imgur.com/a/CpDmsb8
 
You could try booting a linux live cd and see if that can detect all the ram in case its a Windows 11 issue.
