Caution because you can only use MBP8,x SMBIOS under Mojave once/if you've installed the patched PlatformSupport plist. MBP8,x are not supported platforms...
Also be aware that 10.14.3 is probably the very last Mojave version to support OpenGL-only graphics acceleration for HD3000 (provided you install SNB graphics kexts from 101.3.6). Latest 10.14.4 beta apparently totally blocks non-Metal GPUs...
All in all, you'd be well advised to stick to High Sierra 10.13.6 on your E6320.
