Can I run 64bit OS?
This is what my system monitor says
Ubuntu Release 9.10 Karmic Kernel Linux 2.6.31-16-generic GNOME 2.28.1 Hardware Memory 2.0 GiB Processor 0: Pentium(R) Dual -Core CPU E5200 @ 2.50GHz Processor 1: Pentium(R) Dual -Core CPU E5200 @ 2.50GHz My question is, under this specs can I run 64bit Ubuntu? Are there any ways to check, using command line, if my system can? |
64 bit is dependent only on your processor. But to answer your question, yes you shouldn't have problems with a 64 bit OS
|
The way to check is with the output of cat /proc/cpuinfo.
Under the flags section make sure you have lm listed. Here's an example from mine: Code:
flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow rep_good pni cx16 lahf_lm cmp_legacy sv |

For those of us who don't have the Intel model numbers memorized, the next step is to find the page for E5200 on intel.com. I found it at: http://processorfinder.intel.com/det...px?sSpec=SLAY7 Then you find "EM64T" in that page and see whether it is listed as supported, supported by only some revisions, or not supported. In this case, we see supported, so that CPU can run a 64 bit OS. Quote:

I don't mean to imply you didn't know the answer, just that supporting details make it easier to trust an answer. |
