My name is Michal Bergseth, I am 26 years old and I am pretty stubborn. I mean I am such kind of person which dosent give up until I find a sollution to it.

In February 2004 I got myself an PegasosII G3 600MHz motherboard. I allready bought keyboard, DDR RAM and HD. I took the Voodoo 3 2000 PCI card from my Amiga 4000 to my PegasosII and got my system to work after 2 days. Yeah, for once I couldnt understand how to read the CD as it was changed, and that the devices didnt want to show up or work as they should with lots of combinations. Yea, this was like a Myst game for me :) Well, after some very nice help on #morphos I bouth found out thats CD had change to CDROM -;) thanks!.. But the sollution to get my firmware to read all devices, was more tricky. Well, this one, I found out myself. CD-ROM on one IDE channel and HD on the other IDE channel. Maybe this had something to do with my TwinMOS memstick?

Well, in March 2004 I think. There was The Gathering 2004. An huuge event in Hamar each Easter here in Norway. Its very funny, since this Hamar increases its popullation by arround 5000 nerds/computer users inside the famous icehockey olympic hall which was constructed for the Lillehammer Olympic games in 1994. Well, there I bought myself an ATI Radeon 9200SE card for 150,- NOK (our money in Norway,.. we dont use EURO you know.)

During the show, errorbugs started to annoy me more and more. MorphOS crashed at odd times, like Songplayer and mplayer at that time. Also with having only Voodoo 3 2000, MorphOS even crashed on when changing screens. The crashings was unregular. I didnt know when it happened. Sometime MorphOS worked in 3 hours, other times just in 5mins maximum.

So I got some sollutions to try out from lots of people on #morphos which claimed it had to be something with my internal sound. So I bought myself an Soundblaster card :), but that didnt help.

At the very first PUSH, which I find the best ever done Pegasos/Amiga show in Scandinavia in a loong time! A Swedish man helpen my friend and me with installing Gentoo PPC Linux. It took some time, maybe 3 hours :) Well thanks to that mr. dholm. I didnt get the 3D to work under it, but atleast it worked as it should in software mode. Linux at that time was known for bad ATI support so,.. and my ATI Radeon 9200SE card is the worst of them all, but atleast I paid 150,- for it.. so I am happy :=)

Well, the same problems as in MorphOS started to happend in Linux aswell. In Linux such crashes must be much more dramatic than on MorphOS, as Linux needs a proper shutdown. I felt that on my knees for sure. After a while xwindows didnt want to startup as it should etc. Well, the soundproblems was the reason for the crashes here also! What the hell was it??? No one knew.. so I thought many times to send my motherboard away to Genesi for repair etc.

Some Suomi guy told me during these 2 years allmost, that it could be the mem. Well, hehe.. I bought another TwinMOS membrick. I also deleted Linux, since I found it useless and xwindows didnt want to startup anymore :) Sorry dholm, .. But MorphOS is way better to check if hardware got errors than Linux. Because MorphOS simply fully crash :) On Linux xwindows crashed first, then when I switched to the console, it hanged even more.. and when trying to kill dead tasks.. it was not possible and it freezed. Linux is to big and overhyped I think :) I admire though, those sitting with Linux all the time.. your geniouses in computing for sure.. We need you :=)

Well, now in November 2005 I finally bought myself Crucial 512MB RAM bricks! And you know,.. it helped :) It has fixed all of the hangups and strang lockups. Now I am typing, while the mp3 have been running for hours and Ibrowse is as good as it is! With TwinMOS it would crash in the middle of this bad written English article...

Well, my conclusion!:
Dont use TwinMOS. If you comment me with that TwinMOS works without problems, then you sure have to comment. As with G3, it might have some problems with some memfabricks names? Well, thanks to all that have tried to help me in everyway. I have really tried to find this sollution and that it happened Friday November 25 2005 is for me a mystery.

Keep the MorphOS alive! Now I am surfing without strange speedchanges. Windows scrolls smooth after 3 hours, which it didnt when I had TwinMOS installed.

Thanks again to all of you which have been helping me out! Have a nice Christmas and thanks for keeping the AmigaOS and MorphOS communities alive!

Regards,
Michal

what memory can do!

greetings Cor van Londen.

I have the exact same size/speed TwinMOS ram as you do, and it works fine .. these things are rarely vendor-specific but rather caused by broken ram or bad parts from a specific batch.

You should post the complete details (everything on the sticker plus whatever you can spot on the chips themselves) of your faulty ram (if indeed it is faulty (did you atleast do a MemTest EXTENSIVE (and/or REVERSE))) .. also the exact version of your OFW could be of importance as certain versions have exhibited various problems...

Last but not least, this is not the first time you claim that your problems have disappeared, are you really sure they are solved now (and that you didn't happen to change something else when you changed ram)? ;)


- CISC

The TwinMOS brick used:

TwinMOS MODEL NO: M2G5J16A-MK S/N: 349M35M46023487 PC2700 (CL2.5) 512MB DDR-DIMM


Here you have the memtest etc from my new Crucial mem. Well, things are that whole morphos is running better CISC. Before it could just hang when writing an text here with iBrowse and listen to music, thats not happening anymore.

Well, the reasons for me thinking its been gone, is because of the speed going up and down. At some points when the mem was working as it should, MorphOS was running. Then after a while, when it got warmer.. more often crashes happened etc. Now most of its gone, and yes I use MUI4 so I expect it to hang, but I love it.. so whatever.. Well, now it dosent crashes after 5mins.. rather its been working since 09.00 this morning..

Michal

No TwinMOS problems here either.

I can't speak for the Peg, but I've had similar problems using TwinMos memsticks on several pc's. Some motherboards I've owned (MSI, Abit) won't even boot with TwinMos memory. (PC2100, CAS2.5 and CAS3)

Anyway, my point is: every brand of memory has faults, but in mine (and MorphDelf's) case, it seems as if TwinMos is "cheap" and "not so good"

I run PC2100 REG ECC ram in my peg, and never had any problems with it. (although it won't boot with more than 1gig :)

Thanks.

My MorphOS now works even more stable. I changed my keyboard with another one, and now 68k and SDL programs have stopped to crash also.

The only thing left now, is the buggy MiamiDX. MorphOS dosent crash instantly after playing SDL games or listening to mp3s.

With Sonic making a very nice tcp/ip stack, MorphOS will become a nice OS.

Quote:

So MorphOS' stability depends on which keyboard you use. Interesting theory

FYI I use the same keybard on my peg now that you did before (the flat silver logitech), and still no crashes ;)

Some keyboard & mouse combinations can couse bad behavior (like mouse "going crazy")

Don't know if it can also couse crashes... Maybe with almost broken cable or something?
