# WARNING this tool not being optimal for very high memory systems

[sonnguyen-dba]

Hi Alexey Vasiliev,
Can you support "optimal for very high memory systems"?
memory > 3000G

@sonnguyen-dba how much a memory mean "> 3000 G"? Like 5000 GB RAM?

For workstations, the biggest amount of RAM that you can take is around 2TB (For AMDs TR4, X399 chipsets). What kind hardware from 2021 support more, than 3000 GB RAM?

P.S. I ready to support high capacity systems, just provide me math model with test for all combinations of params. Thanks.

Hi @le0pard, I using Oracle X8-8 3TB RAM.
P.S. I ready to support high capacity systems => yes.

Thanks

Ok, but what mean "> 3000 G"? How much memory utility need to support?

[sonnguyen-dba]

thanks, It mean from ("> 3000 G") 3TB.

Thanks, I think we shouldn't waste any more time on this.
Thanks you very much.

Yep, warning is correct. I don't have tests and numbers for high RAM systems for PostgreSQL. So that is why I need math model for this

Thanks @le0pard, I see! Best wishes to you!
