Hardware Talk :: Unsuccess increasing RAM

I haved my lover DSL running over 486/DX2 66MHz with RAM 16MB. Slow, but running.
But when i increased RAM from 16 MB to 64 MB not boot, not memory test, nothing.
I do not think this problem could can exist and i not have motherboard documentation.
My hardward not soport 64 MB memory or exist an jumper, an set, something to resolved it?
Tanks.

Possible RAM missmatch

Double check to ensure you have everything seated properly and then if system will post do a memory scan!

Make sure all your connections are tight and well seated after making any physical changed to any machine (I have pulled cords loose and stuff by accident and didnt know) and I hate having to keep pulling the case off for something stupid

I checked connections before write in forum.
This motherboard is very old, i thinks exists an compatibility problem.
Is motherboard av7542 with chipsets SIS85c471 and SIS85c407. Perhaps somebody have documentation.

Does the motherboard take 72 pin modules? If so, it may not accept EDO-ram. If it is 30 pin, the max may be 32 MB.

Motherboard have two slots for 72 pines SIMM memory and 4 for 30 pines SIMM memory.
I installed two 72 pines memories. Each memory have 32 MB.
