# PetscMallocSetDRAM
Set `PetscMalloc()` to use DRAM. If memkind is available, change the memkind type. Otherwise, switch the current malloc and free routines to the `PetscMallocAlign()` and `PetscFreeAlign()` (PETSc default). 
## Synopsis
```
#include "petscsys.h"   
PetscErrorCode PetscMallocSetDRAM(void)
```
Not Collective




## Note
This provides a way to do the allocation on DRAM temporarily. One
can switch back to the previous choice by calling `PetscMallocReset()`.


## See Also
