upgraded cpu's

Recommended Posts

Hi all,

 

I just upgraded the cpu's on my Asus A7M266-D motherboard from Athlon MP 2200's to MP 2600's and was wondering if there was anything I needed to do for the system software wise, ie reinstall the kernel or anything like that. Mandriva 2008.1

 

I wasn't expecting any really noticeable performance improvements and running HardInfo seems to confirm that. In fact in some of the benchmarks I seem to have lost a little ground and others slightly improved. Maybe normal variation. Maybe not.

 

Anyway, one of the reasons I am asking is because Firefox has started randomly freezing up on me when loading web pages. Had it happen here and on the AVS (Audio/Video Science) forum. So far I have only seen this in Firefox. I played WoW for several hours last night and had no problems.

 

Thanks,

Sean

AFAIK you need to do nothing, the kernel will detect the new processor automatically.

 

How much RAM do you have and which kernel do you have installed, desktop586, desktop, laptop or server?

2 Gb RAM and kernel-desktop-2.6.24.5-1mnb to get past the 880 MB memory problem.

 

uname -a:

 

Linux localhost 2.6.24.5-desktop-1mnb #1 SMP Tue May 27 12:42:16 EDT 2008 i686 AMD Athlon XP GNU/Linux

 

Just had another Firefox freeze where I couldn't bring a tab to the front. Had to close the active tab to get back here to continue writing. This time Firefox didn't completely freeze up on me. Guess I could remove/reinstall FF and see if that fixes it. Maybe its just coincidental that it broke after upgrading cpu's?

You shouldn't need to reinstall Firefox, perhaps it's just your Firefox profile that is screwed. You can easily do this by:

 

cd /home/username
mv .mozilla .mozilla.old

 

then run Firefox again to create a new profile. Replace username with your user that is experiencing the problem.

Firefox seems to have cleared itself up for now. Not sure why.

 

I booted into the latest desktop i586 kernel and ran benchmarks with HardInfo. Not much performance difference between any different run:

Not much difference, nor did I expect much, but a little something woulda been nice for my $60. :huh: I guess I fell for some old marketing hype.

 

Thanks for the proffered help and suggestion.

Edit: More likely I just don't understand the magnitude of the changes.

 

Edit: Major edit of codebox for readability. Sorry.

Your motherboard houses 2 cpu's? I am using a A7M266 (single processor) motherboard with a XP2100 cpu.

 

Old school! :pimp2:

You don't have to change anything in the system, nope.

 

I suspect what's happening here is the MP-2600 is not actually much better than the MP-2200. Or, just possibly, you were using manual BIOS settings for the old CPU, so you're actually running your new CPU at the same speed as the old CPU. Go into the BIOS setup and check that.

daniewicz,

 

Yeah. 2 cpu server version of yours. Old school motherboard but it was a looker back in it's day! :D Just trying to milk a couple more years out of it without spending much money on it before I go for a complete system upgrade.

 

adamw,

 

I will look into the BIOS settings. Right now it is set to JumperFree and as far as I know should detect the cpu's on its own.

 

Thanks all.

 

Sean

You might need to go into the BIOS and choose Optimised Defaults as it'll help change everything for the new CPU. Although, this is based on the BIOS's I see in most home-build systems.
