32/64 bit?

coops1992 · 3 Nov 2012 at 13:59

hello,

i have an old motherboard and processor lying around, i need to work out if it is able to run a 64 bit OS. I know theres ways of doing it if it had an OS installed but at the moment itts on it own and not running anything,

Whats the best way to work out what it it before i spend time and effort inot building it and money on getting a PSU for it>

Any info etched on the CPU surface or die package?

coops1992 · 3 Nov 2012 at 14:04

if thats the only way im going to have to clean it up, its got a load of thermal paste dried on the face as i havent used it for a year

INTEL Core 2 Duo
6400 SL9S9 MALAY
2.13Ghz/2M/1066/06
Do i need dets from the mother board too?

i presume this is it here, http://ark.intel.com/products/27249/Intel-Core2-Duo-Processor-E6400-2M-Cache-2_13-GHz-1066-MHz-FSB and yes it can run 64-bit

Thanks

im presuming it is to, although there was no E inscribed on the chip itself before the '6400'

Can the motherboard affect whether or not 64bit os will run?

coops1992 · 3 Nov 2012 at 14:21

Thats definately the processor just found a pic of ad E6400 on google and it doeesnt have the E enscribed on it. Thank you

out of interest, what would happen if you load a 64-bit OS on a non 64-bit CPU ?

It doesn't load.

coops1992 · 3 Nov 2012 at 14:36

does the mother board afffect if 64bit os can runn or is it only dependant on the CPU?

stulid · 3 Nov 2012 at 14:42

Its the CPU that matters.

I thought that all CPUs from 2006 onwards (e.g. Intel Core²Duo and AMD X2 3400+) were 64-bit ready to make way for the release of Windows Vista later on in that year?

No. Intel Core2Duo T2300 (2006) has 32-bit instruction set only, for example. Vista has nothing to do as there are both 32 and 64-bit revisions.

That's a Core Duo, not a Core 2 Duo though. Core Duo (Codename Yonah) was mobile only and based on the older Pentium M CPUs, whereas Core 2 was a desktop and mobile platform, and was a new system entirely (and all 64-bit).

I remember CPU's as early as 2003 (skt 754 Athlon 64s)? being 64-bit ready.

Rooster212 · 4 Nov 2012 at 20:19

AMD chips were 64 bit before Intel ones were I believe.

Unless you have more than 4gb of ram go for 32bit, uses less space and more programs will work (that said a majority will work on 64bit these days)

Worth getting 64bit, you can carry it over for whenever you switch it up down the line.

First 64bit Intel chips were the very late Pentium 4's. I have a P4 3.06 HT running Windows Server 64.
