Does upgrading motherboard/CPU actually work? Also, 64bit vs. 32bit....
I've never done this before with any OS so I'm a little wary in general. But I have a P3 800 that I'm thinking of upgrading as prices are really low and I have a little money right now. Is it a fairly trouble-free process to install a new motherboard/CPU on an existing install or do you have to reinstall the OS? As I've never done this before I have no idea how it will turn out, if SuSE will recognize the new hardware and just deal with it or if it will be looking for old hardware when it boots and be unable to readjust. Thoughts on this? Also, if I decide to do it, is there any advantage to going 64bit? Obviously that would require a reinstall, but I'm curious, though. Since I have a 64-bit OS it's pretty tempting. Are there any performance gains to be had over 32-bit? For help in answering this I'm a java/web/database developer. So that + reading email, ripping MP3s, burning CDs, browsing, etc. are what I mainly use this computer for. Any advice is appreciated. Preston

If your using 9.1 then you should be able to go from what you have now to a new MB/CPU without a reinstall. If you pick something that's the latest and greatest then you may have issues that not even a reinstall will fix. I went from an AMD Duron 800mhz /w an ASUS A7V motherboarrd to a P4 2.4ghz on an ASUS P4PE/GE using SUSE 8.2 with no issues at all... in fact it's still running 8.2 because I'm lazy and I use my 17' Powerbook 99% of the time now.
Also, if I decide to do it, is there any advantage to going 64bit? Obviously that would require a reinstall, but I'm curious, though. Since I have a 64-bit OS it's pretty tempting.

Yes, you would have a great advantage. The bus through put in the AMD64 is quite a bit faster then ia32 systems. I think you'd see a large difference. But with this choice you'd have to reinstall because you would be using the AMD64 compiled versions of the OS. But this shouldn't be a big deal.. just remember the mantra of BACKUP, BACKUP and more BACKUPS. :) -ben -- "There is no need to teach that stars can fall out of the sky and land on a flat Earth in order to defend religious faith."

over time I've gone from AMD K6 to P3 to Athlon XP to Athlon 64 and back (today) to an Athlon XP again. If your hard drives are hanging from the regular IDE controller, swapping mobos should be no problem. Afterwards, you'll need to run Yast2 to reinstall the drivers for your network adapter, sound controller, etc. If you go from P3 to AMD, you'll need to re-install the kernel, but do it last, make sure it works with the older kernel.

64bit is being taunted as giving you higher performance. Note that these are new motherboards, they may not be supported 100%. I bought an MSI board with an AMD 64 3000, it comes with two SATA controllers and 4 IDE ports (one set by Promise, the other set by VIA). Both SATA controllers are supported by suse, but the Promise IDE controller was not and I could not get IDE drives on that bus to work. In fact, after removing the drives my system would not boot (plugging the drives back in allowed the system to boot, a pain in the ass). I swapped the MSI board in and kept my suse 9.0 installation intact. I did not see an appreciable performance improvement. I even tried a new installation on a separate partition of the 64bit version of Suse 9.1, I couldn't feel a big difference, but i didn't use it much. I decided to go back to an Athlon system. I write software, too late I realized that developing on the 64bit system, it would give me 64bit-processor only binaries. In our company we don't use 64 bit systems, and I don't have the time to set my system up to cross-compile for 32bit processors. Since you develop databases, make sure your applications will not have portability issues if you go for a 64 bit system. Another potential problem are general applications ported to 64 bit systems. There may be subtle issues with some software packages compiled for 64bits. I don't know of any at the moment, but I'm not up-to-date on that topic. The bottom line is that swapping mobos is not terribly difficult, just pick the right board for you. -- Rafael

I have both this 32-bit Athlon XP3000+ box and a 64-bit XP3000+ laptop, same amount of memory, but the laptop has 1024K cache as opposed to 512K on the 32-bit box, so that may make a difference. I can start a kernel compile on the 32-bit more than 5 minutes ahead of the 64-bit laptop and the laptop will finish a goodly 2 minutes before the 32-bit box. The cache is double the size, but the processor speed is only 1800Mhz on the laptop, 2200 on the 32-bit box. There is a mix of 32-bit and 64-bit apps and the blurb says you can expect no degrading of performance on 32-bit apps, which indicates that you won't see 32-bit apps running any faster. Building from sources -- still a number of apps don't build, probably a SuSE thing, suddenly it will be linking with libraries in /usr/lib64, /lib64, etc., i.e with libsuffix=64, then it heads off into /usr/lib and complains it can't find a library that's only in /usr/lib64. I had a guy from SuSE on here who suggested I try everything I'd already tried, then the guy who said he built the 64-bit apps was on, he said everything should build fine, if you blah-de-blah, I said now way, haven't seen him on since. May be 9.2 will straighten that out. I've often wondered if there are similar problems in other distros, but I've not been able to find any via google. Regards Sid. -- Sid Boyce ....
