kernel panic attempted to kill init !


Ok, I browsed over the previous threads about this problem. But none of them explains about my situation
Well, Here is what happend ,
I have a celeron 600 128 MB Ram server ( 2 stick Ram)
I bought 2 x 256MB RAM sticks more from bestbuy. Installed them into the server (All 4 RAM slots are now full) then tried to make a fresh install... While the installation goes through, (It's a RH 7.1 system)
It stopped responding and gave the error I mentioned in the subject. kernel panic attempted to kill init
Well, I took off the old 2 X 64 MB RAM sticks and left just the new ones. It gave me the same error..
Then I installed them again and removed the new ones 2 X 256 RAM. There we go, It worked..
Why my new RAM's won't work?
Any ideas??
Thank you.

checklist

maybe u passed all these steps but it's worth a try.
a: are the ram sticks the proper ones suitable for your system?
b: did u check your mobo's guide to check if 2x64 + 2x256 is possible?
if yes: make sure u have this setup
Slot: stick:
1 256mb
2 256mb
3 64mb
4 64mb

so dont do: 64,64,256,256 or -,-,256,256.
it's just a wild guess it's the only thing that comes in my mind

I tried every possibility and could only be half successful.

Now I can only run 3 Ram Sticks, they're
1 X 64MB
1 x 64MB
1 x 256MB
there is no other way that my linux accepts the 4th one, which is the other 256MB stick..
By the way, this is a second handed server so I couldnt' check the mobo's manual.
Thanks..

As KayJay said, the system might not support the 2x256/2x64 RAM configuration.

Two other possibilities:

1.You're exceeding the maximum amount of RAM that can be installed in that system. Maybe the max is something like 384M; you would have to get the mobo specs to verify that.

2. Replace the currently-installed 256M stick with the "leftover" 256M stick. If it doesn't work, you just found your duff RAM stick- exchange it for a good one.

Ok, now get ready to hear the weirdest..
I have created a small table showing what happens when I switch RAMS..
I'd like to let you know that 2 X256MB RAM sticks are NOT the same physically. One of them has a total of 16 chips on it, the other one has 8 (one side only)

1st test

Slot1 Empty
Slot2 Empty
Slot3 256MB RAM (8chips)
Slot4 256MB RAM (16 chips)

BIOS shows 512 MB RAM but computer won't boot..

2nd test

Slot1 Empty
Slot2 Empty
Slot3 256MB RAM (16chips)
Slot4 256MB RAM (8chips)

BIOS shows 393MB RAM and computer boots OK.

3rd test

Slot1 Empty
Slot2 64MB RAM
Slot3 64MB RAM
Slot4 256MB RAM (8chips)

BIOS shows 262MB RAM and computer boots OK.

4th test

Slot1 Empty
Slot2 64MB RAM
Slot3 256MB RAM (8chips)
Slot4 64MB RAM

BIOS shows 393 MB RAM and computer boots OK.

Now guys, something's wrong, the 8 chipped RAM is bitching.
I couln't completely understand what is going on..
Is this 8 chipped RAM junk?? or what , man,
now I'm confused..!!

Lightbulb re: Problems with one-sided ram

I also had problems running this "one-sided" ram in my celeron box which was an ABIT BP6. Using the 2-sided (16 chips) 256MB peices solved it. I think they call that sort of memory "registered" or "bufffered" - not sure, just know it worx.

Anyone have more info on this?

O.K., I'm curious...

Post the part numbers for the chips on each stick of RAM and I'll look them up.

Looks like your basic PC-133 unbuffered SDRAM. If the stick has 8 of the chips, it's a 256M stick.

What's the number of the the other 256M stick?

If you haven't run off to blow up BestBuy yet, try putting the two new sticks in slots 1 & 2 (and leave slots 3 & 4 empty!) I've heard that some mobos can use unbuffered/unregistered RAM in the first two slots only.

this is p'bly unnecessary and after the fact, but I'd say that motherboard won't take above 384Mb of RAM, no matter what you do... don't bother getting another stick, 'cause it p'bly won't work any better :-/

Howdy,
i think your ram problem is to do with the "density" of the first stick in either pair of slots - your 8 chip 256MB is the most dense as it gets 256MB on 8 memory modules - your 16 chip 256MB is less dense as the 256MB is spread over more chips ( still with me) .
The first Dimm in the pair of slots is probed by the m/board to assess what memory you have - whenever the 8chip dimm is the leading dimm in a pair it is "strapped down" to 128MB as the board can't handle the density - the second dimm in the pair is then ok to proceed at 256MB. When ever the 8chip dimm is the second dimm in a pair the other dimm has been probed at a lower density so the board has a spaz when it tries to apply that density to the more dense 8chip dimm.
In conclusion - that dimm will only ever run at 128MB ( as the 2nd dimm in a pair) as your borad can't handle it.
HTH
