64 Bit supported?

Hi i would like to ask if my pentium 4 Prescott 3.0GHZ supports the 64 Bit cause in the BIOS i read it does but i am not that sure
 
It depends, i have a Pentium 4 Prescott 3ghz, but it aint 64bit, it was socket 478 tho, they started putting 2mb l2 catch and EMT64 on the cpu's with LGA 775, download CPU-Z that will tell you if it does, its not a big deal if it doesent, are you wanting to upgrade to windows xp 64-bit edition?, if so, your not going to see anything good, and i dont think alot of stuff is supported by it too.
 
No it doesn't it's a Socket478 i just wanna know cause in the BIOS said 64 Bit supported:stickout: but i think it's the motherboard who supports 64 BIT

Forget that it's an LGA 775 but before upgrading i want to know the advantages and disadvantages of the 64 bits
 
hmm thats wierd, never thought you could get 64-bit cpus that were in skt 478, it must be the mobo that supports 64bit then :s
 
well, are you sure you CPU is socket 478? is the actual socket the CPU is in like a cream colour, or is it metal and black looking or somthing?
Also how much L2 catch does CPU-Z say you have?

*EDIT*** well if the mobo i am looking at right now is the same as yours, you cpu is LGA 775, and CPU-Z will tell you if its 64-bit, just look for EM64T.
 
If it's a Pentium 4, it doesn't have EM64T. Some of the newer Pentium D's do (I believe it's the 6xx series and up).
Look on the Instructions line on the first tab in CPU-Z. If EM64T is there, you have 64-bit extentions. If not, you don't have them.

The packaging has nothing to do with EM64T. These are extentions added to some of the Pentium D cores.

LGA=Land Grid Array. The pins are in the socket, not the CPU.
PGA=Pin Grid Aray. The pins are on the CPU packaging.

The numbers signify how many pins each socket has. LGA775 have 775 pins, PGA478 CPU's have 478 pins.
 
It supports it, CPU-Z sais mine is A Pentium 4 630 And in the instructiuons tab there is EM64T:cool:

Now before upgrading tot 64 BIts i would like to know if is a good upgrade or if is better to stay in 32 bit?


EDIT:The cache is L2 2048 Bytes
 
This is a Wikipedia article about EM64T:
EM64T - Wikipedia, the free encyclopedia
I'm no expert on this topic but it would appear as though EM64T was first used on the E revision of Prescott P4s. Revisions F, 2M, and on the Core 2 Duos and late Celeron Ds. The article is a lot of technical garbage but I think that EM64T is implemented on late P4s.

Stick with 32-bit for right now. 64-bit support will come, but I don't think it's going to hit full force until Vista comes out. Major hardware players are all supported, but if you have a niche market product, good luck.

Unless you have a specific need for 64-bit, I'd wait. There's still work to be done on it. If you do go, make sure any and everything that important to you has 64-bit support.

You're right:good: i'll stick to 32 Bits for now if it hasn't reached full support ill wait and when ill come to full power:guns: ill upgrade to 64 bits. for now let's not change nothing:beer:
 
Anandtech reviewed the new beta revision of Vista -- it is STILL lacking. If you're a gamer, don't even transition. They have made some improvements in Vista, but the main thing you'll be getting is the "look and feel" - pretty much they're begining to turn into a Mac OS with how windows are presented and all the "pretty" colors.

The real benefit from 64 is that security is about to increase.
 
Many people won't necessarily switch for real functionality but because they want the newest OS. I know I will get it simply because I want it.
 
well you can get it now, there is an open beta on the Microsoft site, cant remember which one, but they let you download it, and try it untill i think some time in june next year, i think june 7th maybe?

Anyway, when i first got my AMD64, i tried 64-bit windows, it was not very good, infact it was slowing down my normal 32-bit apps, and some drivers would not install, i gave up in the end and went back to 32-bit windows xp pro.
 
I would to ask, if i want to try Windows x 64 Edition i could make a partition which in the boot up i could choose between 32 bit and 64 bit?
 
So i think i will do a partition for Windows X 64 and one for my actual Windows Professional in this way if i am unsatisfied with 64 bits could stick to 32 bits:chk :chk:
 
no, i bought this PC, had an illegal version of x64 edition, ........ IT SUCKED, I couldn't install my webcam / gamepad / USB Modem drivers, and there were no 64 bit ones on the internet,

32bit apps commonly use a 16bit installation program or something, but i know that you can have:

16bit & 32bit
32bit & 64bit

But you cannot have:

16, 32 and 64,
64bit and 16bit
