old skool dimms

[MrTom]

i have an old box which i'm upgrading slightly to be my new firewall.
the motherboard itself has 4 EDO ram slots of which two are used and what looks to be a 168 pin dimm slot.
i bought a 128mb dimm ($20 - silly prices) to replace the old edo stuff but hit a problem when putting it in. the slot is the correct length and has the right "blocked pins" to match the slots in the bottom of the dimm, but the two catches on either side seem to short, making it impossible to secure it properly.
has anyone ever used this kind of ram? is it really the same as modern day stuff, or was it before the design of sdram was settled?
TIA

Unlike SIMMs, DIMMs need to be pushed down into the slot much like an ISA or PCI card. If the slot was empty for a long time it could have dirt or some foreign material in the bottom stopping the DIMM from going all the way down.
Hope this helps. Good luck.

yeah, i'm ok with dimms. after i couldn't put it in the old box i just chucked it in my main machine no problem. and as i thought, the catches on the old dimm slot seemed to be shorter - but there was not much room in there and it was dark so maybe i wasn't trying hard enough

i just thought i'd check to see if those type of motherboards had the same kind of dimms as modern day machines.

it pains me too much to buy some EDO ram for the other slots when it's so much more expensive and rare than sdram.

Some system manufacturers (ie. Packard Bell, Compaq, HP, etc.) require proprietary memory modules. If you are sure you had the memory seated properly and it didn't fit you may need special memory modules. Go to

and use the configurator to find memory for your particular system or motherboard.
Also try

They are very reliable and may be a little cheaper.
Hope this helps. Good luck.
