SDRAM DIMMs for Laserjet

This is a two-part question:

1) My HP Laserjet 5000 manual does not prohibit non-HP memory chips to be installed in the printer.  It only specifies using either EDO DIMMs or SDRAM DIMMs, and gives their part numbers.  Of course, I want to just purchase top-name-brand DIMMs at the rock-bottom internet market prices.  Non-HP memory is also available at higher capacities than their highest 32MB modules.  I did this clever swap with an older HP230E inkjet plotter using SIMMs from my old Macintosh.  It's been working fine for over two years.  Will I get into trouble with the newer laserjets and the newer SDRAM chips?  Of course I do not want to take HP's advice literally -- I'd rather get advice from third party experts.

2)  What's the difference between regular 3.3v SDRAM DIMMs and 3.3v PC-100 SDRAM DIMMs?  Their prices seems to be the similar.

Yes, you can use dimms with a non-HP brand in the laser printer. However, the dimms in the HP laser printers are 100 pin dimms if I am not mistaken, and they are not compatible with the memory from a PC. We usually purchase memory from Kingston for the HP laser printers.
The PC-100 part in the SDRAM description means that it is meant for a 100Mhz bus, and the standard SDRAM dimms are usually for a 66Mhz bus. Neither one of these will be compatible with the HP laser printer due primarily to the number of pins required by the HP printer.
if you have the HP part number, you might go to:


and see if they have a cross, great memory products, support and warranty

Thanks!  I didn't know that the number of pins is different.  Guess I simply lucked out with the old Mac SIMM in the HP Designjet plotter?  It's been working fine, tough.

Also, thank you Oldgreyguy, for the very helpful tip on Kingston cross-matching.  I've been able to locate their equivalent, and comparing it to the more expensive HP, I think I'll go with Kingston's lifetime warranty.
