Last message on previous page:
I turned off my paging file with my 8GB (BIOS only sees 7.5GB, stupid RD600 crap chipset) RAM and my pc is light speed - until I tried installing a wireless PCI card. I tried 3 brand new wireless PCI cards in all of my slots, and for the life of me could not figure out why my PC would completely hard lock under heavy traffic. Two of the cards were based on Ralink RT2860 and one on the older RT61. I had the newest drivers and am running Vista Ultimate x64 SP1 and was pulling my hair out for the longest time! I took out 3 sticks of RAM and it stopped freezing. I was thinking hmm, wtf mate! Put the 3 back in and it stopped freezing, then realized what fixed it. While removing the RAM I turned the paging file back on.

Apparently, with no paging file some drivers (or maybe something else) just dont operate right.

Paging shoud never be turned off... it can result in performance degradation rather than performance improvement.

Sorry to resurrect this thread from so long ago.
However this is the only article actually testing 8GB of ram on vista but it does so very badly.

The article is quite lacking and it would be nice to see an update including benchmarks and tests with various amounts of RAM.
Also the article mentions performance tests with no pagefile but doesn't show any. This too is not covered anywhere else and would be nice if it were resolved.

Just letting you know as it comes up quite frequently on google searches.

One thing I notice the article was that it mentioned your BIOS will not see 8gb ram until you enable a setting in it to use the memory mapping. While I have only worked with a handful of motherboards out there, every one I have worked with will see all memory installed up to the max it will support without having to enable anything. I have worked with Phoenix and Award BIOS' mainly.

They were talking about memory remapping which is required so a 32 bit OS can remap the blocked memory and use it despite the limitation. Having the BIOS recognize the memory itself has never been a problem and is in fact a prerequisite to use a 64 bit OS. Otherwise the 64 bit OS wouldn't be able to recognize the memory anyway.
