New RAM, and issues.

Hrm.

I recently managed to find an inexpensive source of RAM for my trusty old server, nexus.zyp.org (an old IBM IntelliStation, dual Pentium Pro 200, formerly with 192MB of RAM, now with 448MB). I bought a 256MB DIMM for it (it was beastly trying to find a decent price for this stuff. . . it takes ECC EDO 168 ping DIMMs, which were only really used for high end PPro servers/workstations, and a few early PII's, because then SDRAM came out, and due to it's much greater speed, was quickly adopted), and installed it Friday night.

Within an hour, the machine had crashed, with page fault errors. I rebooted it, went out to get something to eat, and returned to find it down again. With page fault errors. I rebooted it again, and this time it didn't even make it through loading the kernel before just hung.

At this point, I was getting understandably upset. I rebooted it one last time, after letting it set for a few minutes, and this time dropped it into single user mode. I ran memtest on all available memory, and it went through three iterations without finding a single problem. That took almost 9 hours.

At that point, I threw it back into multi-user mode, started things back up, and figured I'd see how things went, since it'd already been up for 9 hours without problems.

When I woke up today, it was still going. Right now, it's at 24 hours, 14 minutes.

So, should I be worried over the crashes?

Or happy that I haven't seen any problems in the past 24 hours?

Bad RAM, and good computers.

Hey, if you ever need more RAM for that box, check out kahlon.com. They carry a 256MB DIMM for for it for $48 (they claim to guarantee compatibility and such), which was as good as I could find.

As far as what I have now, I was thinking mostly along the same lines as you. I'm gonna give it a week or two and run it fairly hard, and see what happens. If I don't have any problems, I'll call it good. If I have one more problem, I'll give a really intense memtest86-from-bootdisk a try, and probably send it back.

It is rather impressive how well these old Dual PPro's hold up, isn't it? Mine started out as my primary workstation back in '97, and when I got a newer computer, it became my primary server. Since then, I've loaded it up with more and more tasks, and it just keeps on chugging. Every six months or so, I start thinking that maybe I should see about replacing it. . . it is rather old, after all. But then I remind myself of the fact that even though it's not the fastest box around, it's still managing to keep up with everything I throw at it.

It looks like we actually use ours for fairly similar uses, too. Mine is my "do everything" box, running my gateway and firewall, which also handles DHCP for the LAN, hosting a couple of small web sites (my personal one, a few screw around ones, and a few for friends), acts as my primary DNS server, mail (and mailing list (thank you Qmail/ezmlm)) server, database server, ftp server, jabber server. . .

Come to think of it, this old box has probably been the most stable, reliable, and hard working machine I've owned.

Thank you, IBM. You made some mighty fine dual Pentium Pro machines. ;-)

RAM issues.

Nope, haven't touched a thing, other than the power button.

I was actually rather worried that it may be heat related, as this box is getting rather. . . erm. . . crowded. . . at the moment. And it does get a little warm.

I figure I'll give it a good week or two,a nd if I haven't had any additional problems, I'll call it good. If I have one more problem, I'll send it back for a replacement.

200mhz P-Pro

Heh, you guys are gonna LOVE this... I found an old IBM dual 200mhz P-Pro on BABER.com for 90 bucks as a bare bone. I mean BARE. No memory, no hard drive, nothing but the case and motherboard with 1 processor in an antistatic bag.. I had a few processors I picked-up at computer shows for like $15 - $20 bucks, just because the things are so damn big and pretty...heh. Anyway, the reason why the processor wasn't in it's socket is because some idiot had managed to pull the cpu sockets off the motherboard leaving behind some pins soldered in and some sheared off at the board. Now, i'm an electronics tech so I have a PACE desoldering station and went to work removing the old pins or what's left of them. After trying to find replacement ZIF sockets for about 2 weeks for a Pentium Pro I gave up. I decided to solder the processors right into the board. This created a problem, because now I don't have a base to clip the heat-sinks and fan assemblies to so I used some thermal epoxy and away I go. Hunting the drivers down for this thing was fun and playing Intel mechanic, even more fun. This thing runs like a champ and easily replaced my old burnt-up server. I just thought you fellas would enjoy hearing my little adventure with my $90 dollar 90 hour P-Pro project. Keep On Servin'.
