[Failing] Mac Mojave, OpenCore, i3-540, Intel DH55PJ board

I am trying to install mac Mojave on my i3-540 with intel DH55PJ mother board by following opencore guide. But there is some issue-

1. Not booting to mac installer
2. Open core boot menu not showing install mac Mojave
3. Whole process is damn slow.

Please guide me to get Mojave working in this old pc. Thanks.
