CF-M34 RAM Problem

wasp61 · October 30th, 2009, 05:23 PM

I have three Panasonic Toughbook CF-M34 laptops. All have 933mhz processors, 256 mg RAM and 100G+ HDD. I bought them as parts or repair machines and after a few problems were worked out, they all run great.
The one problem that I can't seem to solve is how to add additional RAM. I have tried adding 256 mg using the directed chip (256mg pc133 3.3v sodimm sdram) but once installed all the machines wil do is beep at me and not boot up. I don't have a clue as to what is wrong.
Anybody got any ideas?

You checked the beep codes to see what the problem was (as in what the beeps mean)?

**EDIT: The beeps that wasp61 heard are called "beep codes", and different patterns and lengths relate to different problems. Usually when you hear these, it's a good idea to google what they mean, because they are important.**

Beep codes? Never heard of them.

OK, Beeps relate incompatiable or defective new memory module. Thanks TC!

No problem.

Oh, and if you hear any beeps in the future during boot, assume that its a beep code, and google what it means.

Sorry for the post spam, but one last thought:

If you want to check and see what RAM is compatible with your computer, you can always try and use this: http://www.corsair.com/configurator/default.aspx

If your computer isn't listed there, then google it.

edit: and this interesting tidbit from Wiki;

"Q: Can you upgrade the RAM past 192mb?

A: Yes, but not very efficiently.. 128mb in the slot gives you 192mb total, 256mb in the slot gives you 192mb again but a 512mb gives you 256mb in total. So if you have a spare 512mb SODIMM going to waste its worth doing. (Update: See memory module density for a possible explanation!) (Update 2: the 256/512mb upgrade was with this SO-DIMM)"
