Mixing memory is always risky, as there is likely to be incompatibility between the modules. This is likely to be the case here.

If using multiple modules, it is usually advisable to use modules from the same dual or quad channel kit to ensure inter-module compatibility.

So, ideally, get a dual (or quad) channel kit to replace all of the existing memory. The existing memory could be sold or kept as back-up.

Could try raising DRAM Voltage and/or memory controller voltage, but no guarantee that the modules will work despite voltage increases.
