SLURM script for running RSEM star fails

If you have worked on cluster with submitting jobs, please help me in resolving the following error.

I am running rsem pipeline to generate star index. In principal STAR requires more than 30G of RAM for human genome.

I have following script

#!/bin/bash
#SBATCH --mail-user=<your_email_address>
#SBATCH --mail-type=end,fail
#SBATCH --job-name="job01"
#SBATCH --mem-per-cpu=10G

rsem-prepare-reference --gtf ~/Genomes/Homo_sapiens.GRCh38.100.chr.gtf -p 5 --star --star-path ~/Tools/STAR/bin/Linux_x86_64/ ~/Genomes/Homo_sapiens.GRCh38.dna.toplevel.fa ~/Genomes/GRCh38_100
 

The process fails as soon as it starts to generate genome files using star. Below is the error complaining about the memory.

I have put 5 threads for star usage and 10G for each cpu.

here is the error

EXITING because of FATAL PARAMETER ERROR: limitGenomeGenerateRAM=31000000000is too small for your genome
SOLUTION: please specify --limitGenomeGenerateRAM not less than 168632691637 and make that much RAM available

Plase check if you provide correct parameters/options for the pipeline!

Could anyone of you tell me how to fix this.

Thank you
