I would like to know if it have anyway how you can see your 9GB of ram without installing a 64 Bit OS....

Currently i have vista 32 Bit on my AMD system and i am seeing 3.35GB out of my 4GB, and on my Intel system i have vista 64bit i am seeing all 8GB of ram.

My question

Does it have anyway how you can do this with Xp/Vista 32Bit to see all 8GB of ram?.

questions to ask yourself..is your amd processor a 64bit or 32bit..does your bios need updating..but to answer ur question
It's not just Windows, it's all systems. This is not OS specific, this is a
result of the BIOS. The system can only "address" up to 32-bits of ram. When
hardware communicates, you're really just sending data to it just like you
would store data in memory. This is why hardware in your system uses a
"memory range".

There is no way around it in 32-bit processing, no special switches, no file
replacements, no nothing. The maximum addressable space is 4GB--period. Your
SYSTEM (not OS) has to use a certain amount of that to be able to
communicate with devices.

A 64-bit OS does not run into this limitation.
ur welcome

exactamente....perfect explanation....so the simple answer to ur question is that u wasting ur time by buyin anyting more than 4 gb for ur 32bit system

but on dat note eekipoo, u seem knowledgeable so lemme ask u this....the current set of athlon '64' and intel core 2 duo processors which support 64 bit processing but are not themselves 64 bit architecture......will they support the 4 gb+ ram on a 64 bit OS?

Theoretically the 64 bit architecture is supposed to allow for addressing of 16.8 million terabytes of RAM. As a result limitations have been placed to limit the amount of addressable RAM. For example, the Athlon 64 is limited to 48 bits of the 64. This would (theoretically) mean 2^48 bytes of RAM are addressable...i.e. 281474976710656 bytes

eekipoo, thanks for the info. Definitely keep this in mind while searching for my next laptop. What I have to ask, How useful is all that ram to gaming. is'nt your FSB speed the ultimate fctor that would tell you how much ram will help your game?

bushwakka,
The current generation of CPU's do in fact contain 64 and (even) 128 bit registers. In this respect they can safely be marketed as being '64 bit' without the risk of enormous lawsuits for false advertisement. The use of a 64 bit address bus (physical or virtual) however presents enormous physical complication owing to the large address space. It is therefore safe to say that I did not use the wrong terminology.
