Blizzard 030 dont like my 32simm?

[ElectroBlaster]

Hi everyone :)

k i have a blizzard 030, my original phase5 one that i owned from 96 to 99 i think? anyway i got it back and also aquired some kingston 72pin simms that were still sealed and never touched so....

i took the original 16edo simm out and whacked the 32 in.. made sure the settings were right, 60ns etc!
the amiga will work for around a minute and will hard lock :(

the tower has a 200watt supply in it so i doubt its power related?
anyone have any pionters/advice?

:)

And by putting the original 16MB SIMM back in everything works fine ?

If so then I'd have to say either a faulty 32MB SIMM or an incompatibility with the Blizzard 030 :(

Hola, Electro. :)

I had similar trouble when trying to source a 32MB SIMM. Had to return one to the shop I got it from, although there was technically nothing wrong with it.

One possibility: your new SIMMs may be 'HyperPage Mode', as opposed to Fast Page Mode. Amiga cards don't seem to like this type, either reporting only 50% of capacity (problem I had), or not working at all.

Before replacing the new SIMMs, if possible test in another machine (PC if possible), just to be certain that they aren't faulty.

righty oh then!

all 8simms were tested in an old super socket 7 board with a k62 450 on it! the machine loved em! it seemed so much faster LOL!

i pick a stick at random, fit it and get 32.blah blah whatever! its same numbers everytime so nothing changes their!

it can work for 5mins or 5sec's, the disk drives can die on me, also the ram disk will bomb :( its gotta be the blizzard not liking this ram.... ahh well :sad

gotta stick to a diddly 16meg LOL

Also note that their could be a compatibility issue with Double Sided vs. Single Sided RAM. I've seen these packaged in both the SIMM and DIMM module formats now.

Even on PC mobo's this can pose a problem as some don't like one kind vs. the other kind.

If the 32MB SIMM has RAM chips soldered to both sides of the module then this is double sided, if only on one side then single sided. Kinda like the old floppy disk thing ;)

Also another thing to look at is the chip density, this is the actual chip size like 1Mb x 4 or 4Mb x 8, etc... This can play a role as to why it doesn't work, again a compatibility issue with the board.

[ElectroBlaster]

they are double sided for sure and 4mb x 8 i think?

shame really as kingston is a good make among pc overclockers so i thought the amiga would be sweet with them in!

You may find that plain jane generic-generic POS's work just fine in the Blizzard board :D

[ElectroBlaster]

suppose its best to get shot of these simms too a pc owner and then try to get some different brand then!

anyone know what make would be most likely to work 100%?

The best way to know whether a ram module will work or not, is to test it. I found a working SIMM for my Blizzard 1230-IV after trying four or five different SIMMs :rolleyes
