Thread: new motherboard help

all 32 bit os can support a maximum of 4GB only .... its has nothing to do with how the os ... more to do with 32 bit processing

32 bit Vista supports 4gb

really i didn't mean to contradict with others view.
To my knowledge, 32 bit os will have max of 4096 MB of address space.
it shares this address to all the device in the system like Display,port id and etc.
so the remaining address space is allocated to Main memory i.e RAM
that why we get 3.4 Gb RAM even we have 4GB installed.(i.e rest are unused.)

thank shadow for the answer.

correct
The various versions [of Windows] reported 3GB because that's all that was available to the user. The rest is used internally for housekeeping, which certainly makes it supported. That has been fixed with [32-bit] Vista SP1, which now reports all installed memory up to 4GB.

The answer depends on what u mean by "supported"

but shadow , i have used 2003 server sp2, it detects all the 4GB ram in my system.
it is also a 32 bit os.
do you know, how it is possible?

If you are ok with a little technically inclined answer u can look here...

Yes Windows Server and Windows Vista 32 bit will show you 4 Gb ram

xp and all these 32 bit os work the same way ....

only Vista and server have been corrected to show 4gb ram
There is no [or insignificant] difference in the way xp, server 2003 , 2008 and vista 32 bit use the 4gb

I know exactly how it works [Technically] .... i am just trying to explain it in non technical simple terms

Interested people can read up 'Memory addressing techniques' to get an idea about that

Both the 'old' and the 'new' pentium D are based on the NetBurst architecture which is the same as that used for P4
So like u said it can be thought of as 2 p4 cores on a single die .

Under Pentium D Intel introduced 2 processor families Smithfield and Presler .... i guess thats what u r referring to as old and new Pentium D ?

well, i need to make a correction. Wat i meat by 'new' is pentium D is pentium dual core. Pentium dual core (E2140, E2160, E2180, E2200, E2220) is based on the 'core architecture' .
You can see that here :

@ rajan1311 , ShAdOwCoN

Both of you guys are enough to confuse everyone about what processor is wat.

Yes i never said Pentium Dual core was not based on core micro architecture ....
You made a small mistake i.e

New/Old Pentium D is not Pentium Dual-core .... Pentium D processors are completely different .... Pentium D processors have been phased out [following the old Net Burst architecture]

Intel Pentium Dual-core is very similar to Core 2 duo so much so that many non technical people cannot make out the difference .....

quoting from same link

Although using the Pentium name, the Pentium Dual Core is based on the Core technology, which can clearly be seen when comparing the specification to the Pentium D series. For example, the Pentium Dual Core has a maximum of 2MB of L2 Cache while the Pentium D processors can have up to 4MB of L2 Cache. But the major difference is the Pentium Dual Core processors only consume 65W peak while the Pentium D consumes a considerable 130W peak consumption which shows its relation to the Core power-saving technology. Despite having a smaller L2 cache, the Pentium dual-core has proven to be much faster than the Pentium D under a variety of CPU-intensive applications

So

--> Pentium D is as different from Dual core as C2d is from Pentium D. So its wrong to call Dual-Core as New pentium D . people will def misunderstand [like i did] and will not know what you r referring to

--> My statement that Core micro architecture was never used before c2d still holds good because

The first c2d based processor was released around the year 2006
The first Pentium Dual core processor was released around the year 2007

After that ofcourse it was used by quad cores and all those till Nehalem based processors were released


So here is the hierarchy

Pentium 4 [Net Burst architecture] Outdated
Pentium D [Net Burst architecture] Outdated
Pentium Dual core/c2d/quad core [Core architecture] Current

yep i have made a mistake.

i was under the impression that the pentium D and pentium dual core were the same (i mean same brand name). But u have made things a lot more clear. Thx.

thanks pal.
i read it and had some info.

thanks for this
