64bit OS but my thinkpad shows only 3gb ram

[mattbiernat]

I am not sure where this topic belongs. I got a 64 bit Windows 7 on X300 but my thinkpad only shows Total Memory of 3061MB. Any ideas?

You sure you have 4 GBs (not 2+1) installed? Look under Control Panel -> System, there you should be able to find the complete amount of RAM installed.

Cheers,

EDIT: Sorry, I oversaw that you have Win 7 beta installed...

[mattbiernat]

yes under computer properties it shows:
Memory (RAM): 4.00GB
System Type: 64-bit Operating System

Hm, probably some reporting bug in task manager of the beta. If you have any heavy application (or some suitable benchmarking utility for the purpose), try to launch multiple instances of it to max the physical memory usage (green bar), you should be able to cross the 3 GBs if it´s only a reporting bug of the beta...

hmm i tried opening like 22 Ie windows but the good old days of FF or IE eating all of your memory are gone. where can i get a benchmarking software to increase RAM usage?

You can try Passmark BurnIn. It´s not exactly a benchmarking utility, but it should do for the purpose

Interesting reading! Though I have to disagree with the author that there isn´t much point in installing 8 GBs for "normal" users, it actually has...

Back on topic: Win 7 x64 should be able to use nearly all 4 GBs on the new machines (like X300) just like Vista x64 does, right? (I think 1 GB difference is pretty much for reserved addresses, besides, a X300 doesn´t have that "much" of hardware....)
