thanks :thumbsup:

now looking in ebay for 512 ram ... pc133 . alls brands is ok ? just look for... 512 ram pc 133?

Most of your older toughbooks were picky about the ram they used.

 

any advice for a known working ram 512 ?? :-(

 

Use PC133 LOW DENSITY RAM module.

 

512MB PC133 SDRAM CL3 NP SO-DIMM 144 pin NOTEBOOK LAPTOP SODIMM RAM LOW DENSITY | eBay

this ok ? is indicate...for toughbook cf-28 :-(

 

Yes, low density RAM with correct speed will work with ANY computer brand, including the "picky ones" like Panasonic or Apple... High density is manufacturing rejects.

 

and this ? in italy ??

RAM KINGSTON SDRAM 512MB PC133 PC100 144 PIN LOW DENSITY | eBay

 

Seems fine too.

 

from ebay seller..

don't know either, as I said from experience you need a 1000Mhz cpu for this ram to work. You can buy and test if it will work or not, if not you can send the ram back to me, I will refund your payment.

 

The 28 was a real pain finding memory that worked. Read here http://forum.notebookreview.com/panasonic/210510-cf-28-f-q-read-me-before-posting.html

 

I have ordered some newer ram sticks available for a CF-28 before. The first three I ordered and they worked. So I ordered more from the same place. The second batch didn't work. Same ram, but different batch number. They were cheap and were sitting for a few weeks so I didn't return them. A few months later I tried them in a IBM T22 and they worked fine so I swapped the ram out of the IBM and put them in the toughbook.

So if you can get a return guarantee. That is the one I would get.

 

Personaly, I'd go with samsung RAM, much better than Kingston (chips can be second choice, and labelling...)

 

..but now seller mail me ...
warning... " max ram in cf-m34- 866 cpu is...512...please buy only une 256 for your panasonic..not 512 "
