Windows 2k8 Advice

I have to put in a Windows 2008 standard server on a windows 2k3 active directory.

Assume this will work fine as long as it is a member server and not a DC ?

Also what is the most amount of RAM this will work with? I can get 16GB of ram for an extra 200 pounds but not sure if Windows 2k8 will go above 8gb on standard edition?

Thanks

Will work also as a DC! There's no problem at all.

Amount of RAM supported depends on edition and architecture (x86/x64). You cand find more details at: http://www.microsoft.com/windowsserver2008/en/us/compare-specs.aspx

Depends on what version of Server you get - 2008 32 bit will only support 4 GB - because that's the general 32 bit limit.  The 2008 64bit version supports 64 GB of RAM.  (Speaking of the "Standard" versions of Server 2008; the limits are different for Enterprise, Data Center, and Web)

You can also make it a domain controller - if you want and it's appropriate - you'd just need to run ADPREP on the existing DC to prepare it for a 2008 DC.

32bit has no such limit in higher editions so this is not 32 bit limit. 64 bit standard edition can use 32GB not 64GB.

32 bit systems ARE limited to 4 GB.  Enterprise and Datacenter allow you to go beyond this using Physical Address Extension (PAE - which STILL has some limitations related to 32bit addressing as not all areas of memory are "extended")

Yeah, misremembered the 64 bit limit - crossed it up with the Enterprise 32 bit limit.

In same post you are writing 32bit is limited to 4GBand can use 64GB.

I know the 32bit limitations. But system will use more memory than 4GB so your answer is not very helpful even if you use some theories about architecture.

Just look at link I provided for amount of memory in Windows Server 2008. Of course we can be smarter than OS developers but usually this doesn't look very well.

Ok thanks

I think therefore what is being said is that if I go with the X64 edition of Windows 2k8 standard then I can go to 32GB but if I stick to the X86 then I am stuck with 4Gb which isn't enough.

Thanks

Yes, you are right. If you can use x64 - use it.

32 GB of RAM on a 32 bit platform and 32 GB of RAM on 64 bit platform DOES NOT EQUATE to the same amount of RAM for all things.  Chastise me for not remembering the details/terms, but there are aspects (I want to say heaps and/or stacks) that cannot and do not take advantage of the RAM beyond 4 GB on a 32 bit system the way they can on a 64 bit system.

As for using 64 bit, Server 2008 R2 is ONLY 64 bit... that said, there ARE some applications that will not run on 64 bit - you would be wise to TEST them first.
