Hi

I have upgraded my ram in my mac mini that runs Windows server 2008 now it crashes a lot.
I have upgraded to 8gb ram, from 4.

As soon as I run windows update it crashes.

here is the dump file I can't really tell what is wrong, if it is the ram or not

flip the two ram (1 -> 2, 2 -> 1), there is maybe a fault in a so-dimm. if still an error occurs, start with only one 4gb so-dimm.

well it had 4 gb before and was running fine but as soon as I upgraded it started doing strange things. I was reading some articles about that it could handle 8 gb maybe it's only 6? :S

See if this helps: Mac Mini - Maximum RAM:  http://forums.macnn.com/58/imac-emac-and-mac-mini/380349/a-guide-mac-mini-ram-upgrades/

Also http://www.123macmini.com/news/story/1155.html

Note, however, that newer Mac Minis will support up to 8 GB of RAM, so it is important that you let us know which model Mini you have.

If it was a new 2010 model, then it should support 8 Gigs of RAM. Can you tell us the model identifier You can get it by pulling down the Apple Menu to "About this Mac" and clicking on "More Info". At the same time, copy  the information there about what RAM is installed and an paste it into a message here. Also, does the Memory Status there show as "ok"?

My suspicion is that you either have the wrong type of RAM, faulty RAM or the RAM is not properly seated.

BTW, do you have the 64 bit version of Windows Server 2008? I don' t believe the 32 bit version supports more than 4 Gigs of RAM.

According to this:  http://msdn.microsoft.com/en-us/library/aa366778%28VS.85%29.aspx

the 32 bit versions of Windows Server 2008 support only 4 Gigs of RAM.

This would make your Mini a "Late 2009" version:  http://www.everymac.com/systems/apple/mac_mini/stats/mac-mini-core-2-duo-2.53-late-2009-server-specs.html  Also:  http://support.apple.com/kb/SP578

Officially Apple says it supports only 4 Gigs of RAM, although other links which I posted above say that 8 Gigs will work. Can't say much beyond that.

It needs 1066 MHz DDR3 SDRAM (PC3-8500) RAM, so it looks like you have the right RAM.

You could run a hardware test on the Mac (which will test the RAM) and see what it says:

At this point I am out of ideas. Apple says that only 4 gigs of RAM is supported. Other sites say 8 will work. I have no personal experience to call upon.

All I can suggest is to pull one of the memory chips and see if the server still continues to crash.

I have tried with only one ram 4gb at it crashed, then I tried with the other 4gb ram in slot2 and it crashed, and now I have inserted the standard ram 2x2gb that came with mac mini and it's working perfectly so what's the conclusion?

That rams are defect or the mac mini can't use 1x or 2x 4gb ram :S

See  if you have this firmware update installed:

http://support.apple.com/kb/DL888

See here for how to check: http://support.apple.com/kb/HT3706

Also

http://blog.macsales.com/2634-confirmed-owc-supports-8-0gb-memory-in-mac-mini-31-machines-2

In short it appears that you need the Mac mini EFI Firmware Update 1.2 installed to run more than 4 Gigs of RAM.
