HP DL380p G8 Populating the RAM

I bought a DL380p with 168GB, was working fine until it came up with a DIMM error on the front panel. I wrongly thought I could just move the ram to a different slot. Now I can only get it working with a maximum of 112GB of ram.

Tried using the HP ram configurator tool but that doesn’t have the ram mix that I have. The ram I have is:

16 GB 647653-081 x4
8GB 647650-071 x12
4GB 647647-071 x2

It’s all HP ram and has been working fine for the last 9 months with no issues, I don’t have an ILO licence so can’t check there.

Any help in getting this working is much appreciated.
