How do I know if my processor can handle 64-bit?

English Hardware
#1

Where do I look to find if I can install 64-bit openSUSE?

My processor: AMD Sempron™ Processor 3100+

#2

the Sempron 3100+. The Sempron 3100+ is based off of the “Paris” core. Paris is the 256kb L2 cache version of Newcastle, with a few features missing, like the x86-64 compatibility.
I found that in a review
AMD Sempron 3100+ Review

#3

Have a look at the result of:

cat /proc/cpuinfo

I have Sempron 3100+ which is 64bit, 4-5 years old, but before that there were 32bit versions.

In a terminal type


cat /proc/cpuinfo

and check if the processor lists the lm flag (long mode) then it is 64 bit.

I suppose you want to know before hand. But if you try to install the 64bit version and the processor can’t do it, the install program will stop and display a message that it cannot proceed.

From Windows you can examine using wmic (assuming you have it):

wmic cpu get datawidth

Ideally, that should give you 64 if 64bit capable.

You can also make normal Win32 WMI requests for the info.

Can’t guarantee the accuracy of this… but I think it will work.

Looks like some Sempron 3100+ are, while others are not 64-bit. If you have the part number (it is written on the chip itself) you can tell exactly.

“Paris” (Socket 754, CG, 130 nm)

* All models support: MMX, SSE, SSE2, Enhanced 3DNow!, NX bit

Model Number Frequency L2-Cache HyperTransport Mult 2 Voltage TDP Release Date Part Number(s)

“Palermo” (Socket 754, D0, E3 & E6, 90 nm)

* All models support: MMX, SSE, SSE2, Enhanced 3DNow!, NX bit
* SSE3 supported by: all models with an OPN ending in BO and BX
* AMD64 supported by: all models with an OPN ending in BX and CV
* Cool'n'Quiet supported by: 3000+ and higher models

Sempron 3100+ 1800 MHz 256 KB 800 MHz 9x 1.40 V 62 W April 2005 SDA3100AIO3BA
SDA3100AIO3BO
SDA3100AIO3BX
SDA3100AIO3CV

So, no for these:
SDA3100AIP3AX
SDA3100AIO3BA
SDA3100AIO3BO

And yes for those:
SDA3100AIO3BX
SDA3100AIO3CV

If I am not mistaken …

Darn. Looks like i’m stuck at 32bit. These were the flags:

fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext 3dnowext 3dnow up

Yes this is 32 bit, but to be honest that should not really make much
difference in performance, it only means you need to install a 32 bit
version.
