New hardware. 64 or 32 bit ?

[Dr.Paneas]

Hello guys,

I've just installed Ubuntu 10.10 32 -bit on my machine. My hardware is Intel Core i5 2500K, ASUS ITX motherboard, 2x2GB DDR3 Corsair So-dimms and Vertex 3 SSD on SATA 3. I use the integrated graphics of Intel.

Do you think I should remove my 32bit installation and then apply a new 64bit one ?
or even with 32-bit it's ok ?

Welcome to UF Dr. Paneas,

Yes if you have a processor that compatible with 64 bit OS's use it, but the 32 bit is fine if you want to stick with it.

Hello and welcome to the forums,

I'd go with 64bit. It is faster.:D

Dr.Paneas,

If you have not yet begun to customize your Ubuntu install too much, installing the 64bit to use all your ram (right now you can use about 3.6 gig of the 4 gig) might be an educational experience for you.

If your computer is only running Ubuntu, you can do a clean install or the 63bit and wipe the disk, no help from is needed.

If you are dual-booting, we can still walk you through reinstalling 64bit without hurting anything (but we need to take a moment to help you plan it, you will have to do a manual install for that).

If you want to install the 64bit, and are dual booting, please do this while running in Ubuntu:

In the Terminal (Menu to: Applications >> Accessories >> Terminal), please run this command: (the -'l' is a lower case 'L')

sudo fdisk -l
Then copy the text from the output and paste it into your next post.

p.s. If you are happy with what you have, don't sweat it and enjoy Ubuntu.

Thanks for the warm greetings guys,

I would prefer to use 100% all of my RAM, instead of using on part of my memory and not all of it. So, I will go with the 64bit.

Maybe a secure ssd erase with gparted or hddparm is a better choice. In the past I have seen a kind of performance degradation using the traditional f-disk way.

Here is the link from G.Skill forums which I am going to follow its instructions : http://gskill.us/forum/showthread.php?t=5901

Hopefully my next forum post will be 64-bit :popcorn:

Hehe great, I am on 64bit Ubuntu now

However, I have to say that I was faced a little trouble with secure erase. The problem is that disk was frozen.



Security:
supported
not enabled
not locked
frozen
not expired: security count
not supported: enhanced erase


I tried to unplug/plug the SATA cable that this didn't work out. So eventually, I removed the power connector from the SSD and the plugged it back. Magic:



Security:
supported
not enabled
not locked
not frozen
not expired: security count
not supported: enhanced erase


Then just typed the appropriate command and disk is erased successfully :)


ubuntu@ubuntu:~$ sudo hdparm --security-erase NULL /dev/sdb
security_password=""

/dev/sdb:
Issuing SECURITY_ERASE command, password="", user=master


Thanks,
Dr.Paneas

Nice work! Don't you feel better already?!?

Nice work! Don't you feel better already?!?

I can't fell the difference, but benchmarks do ;)
btw I've updated the kernel to 2.6.38 prepatched and installed all the new xf86-video-intel, libdrm, mesa-dev and xserver to the latest of ppa-xorg-edgers. Before doing that I was completely unable to play any game...lot's of artifacts on the screen with "zero floating point performance" since I got 0.72 fps on lightsmark :p Hehe, now it's ok :)

Cheers and thanks :)

Dr.Paneas,

You, sir, are a 'keeper'.

I look forward to your future postings...
