Microsoft Windows 2008 R2 Maximum Memory Limits bypass

My Windows admin skills are limited but I believe you can install as much RAM as you want in the server.  Windows will only see up to 32Gig.

I'm curious, why would you want more RAM than the OS can address?

Hello slightwv,

we are running an oracle DB, our users and data are getting bigger. everytime we add new DBs, memory usage rises. Target is to have this server running on 64GB. But with Server STD memory limitation, the STD OS only recognize 32gb.

Hello Lee,

that would be lots of work involve. Not to mention the possible impact to our DBs when we run the upgrade. thoughts?

If the OS can only see 32Gig, how do you expect Oracle to use the rest?  Unless there is some deep level magic I'm not aware of, Oracle takes memory from the OS.  So, it only has access to the same 32Gig.

Solution: Upgrade to Enterprise or Datacenter.

I think the wrong comment was selected. The selected comment was the author restating the problem. The solution is clearly to upgrade to Enterprise (suggested first by Lee, then by PET) or Datacenter (suggested by PET).

Agree - and tomfontanilla - why would you allow your production database to run in an unsupported state.  I don't know if there's any other thing you MIGHT be able to do, but the ONLY way to keep Windows in a SUPPORTED state is to Upgrade the edition or product.  Note: If you purchase Windows 2012 R2 standard, you SHOULD be able to use 2008 R2 Enterprise - which should be a less painful process, I believe a DISM SKU upgrade.  BUT you have to purchase a volume license for it.

Great response

recommendation is good.

noted. thanks.
