Hello guys
This is my first post here at Ubuntu Forums. Been using Ubuntu since Hardy Heron.
I want to run the Ubuntu 10.04 Lucid Lynx x64 on my almost 2 yr old laptop. Itís a Intelģ Coreô2 Duo Mobile Processor P8400 3 MB Level 2 cache, 3GB RAM. These are my complete specs if it would help (http://is.gd/cJ7dc)
This page has details about my processor (http://processorfinder.intel.com/details.aspx?sSpec=SLB3R)
I cant find any information anywhere which would tell me if it would work fine or not. I donít wanna install and damage my processor and motherboard if it does indeed not support it.
I would really appreciate any help and facts which can lead me in the right direction.
Thank you!
Cheers!

According to Intel (http://ark.intel.com/Product.aspx?id=35569), your Core 2 Duo Processor P8400 is 64-bit, so no problem. You can install 64-bit Ubuntu 10.04.

Also, there's no need to worry about damaging anything. If you tried to run a 64-bit operating system on a 32-bit processor, you'd just get an error message saying you can't do it; nothing would be damaged at all.

My laptop is about the same age\spec, and runs 64bit ubuntu with no issues.

Just make sure you install the correct 64bit flash player (if you need flash)it's well documented on here.

Dont worry, if you try to run a 64bit CD/DVD on a 32bit only system, it will refuse to run, and there will be no damage.

BTW, from inside linux, you can run the command-

lshw

Then check the output. What you are looking for is this-


*-cpu
product: AMD Athlon(tm) 64 X2 Dual Core Processor 4800+
vendor: Advanced Micro Devices [AMD]
physical id: 1
bus info: cpu@0
size: 2500MHz
capacity: 2500MHz
width: 64 bits
capabilities: fpu fpu_exception wp 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 x86-64 3dnowext 3dnow rep_good extd_apicid pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch lbrv cpufreq


If there is 'lm' or 'x86-64' in 'capabilities' then you have a 64bit capable systme ;)
