Windows 7 and CF-28 ALSO how to add memory

I recently purchased a CF-28 and would like to put Win 7 on it. Has anyone had any experience with Win 7 on this device? Also, how and where do I add memory?

Thanks,
Brian

 

Memory is under the battery. Factory maximum is to add a 256MB stick of PC-133, for a total of 512MB. But many folks here have good results adding a Kingston 512MB sticl for a total of 768MB.

Above is only for Mk.2 (800MHz processor) and Mk.3 (1 GHz). If you have a Mk.1 must use PC-100 and limited to a 256MB stick.

Read through the FAQ's for more details ....

 

I have windows 7 installed on my CF-28, it works fine. IE8 is slow so I am currently using Opera as my browser. I have not yet found a touchscreen driver that works for Windows 7. The driver for Win XP seems to cause random lockups and blue screens. Once I uninstalled the everything was good.

If you search the forums you will find that several of us have installed Win 7 on our computers.

 

FWIW, both my MK2 and MK3 were able to run 768MB RAM. I pulled some form old Macintosh computers and they worked perfectly. Just PC133 SODIMMs.

 

The Mk1 is the REALLY picky one of the CF-28s; they will ONLY work with JEDEC-standard low-density PC100 RAM up to 256MB(There IS NO SUCH THING as JEDEC-standard PC100 RAM that is any larger).

The Mk2 & Mk3 will use pretty much any low-density 512MB PC133 SODIMM. I've tried DOZENS - only a few wouldn't work and they were all NEW recent-production models. You get a "pull" from any Mac or IBM from a similar vintage, odds are it will work in your Mk2 or Mk3.

All RAMmed up and no place to go...

 

oh puff'ed up dwagon, humor me if you will. What essentially is the difference between low-density and those referred as high-density. Are these interchangable specs or...????

Ron -

No, I'm afraid they're NOT interchangeable; that fact is pretty much the entire point of this discussion.

We've discussed the concept of high-density vs low-density at great length on this forum; the Forum Search will yield about 3 pages of threads with info (That is, threads in which I'VE spoken on the subject; I'm sure there are many more - search string mnem low density).

Essentially, any RAM which adheres to the JEDEC standard for its type (PC-66, PC100, PC133, PC2700, etc) will be what we call "Low-Density"; by definition, it IS the standard used by manufacturers.

As a memory type evolves, manufacturers will modify their design (making their new design NON-JEDEC COMPLIANT) to allow for ever-larger memory capacities being demanded by their customers.

This practice was especially common (and problematic) in the days of PC100 and PC133 RAM; those memory types lasted unusually long in the industry, and as such they survived long past the time when the JEDEC standard for those types was adequate to the demands of the customer base.

As an example - I've seen Xeon-powered servers that use PC133 but support up to 32 GB RAM. The JEDEC standard for PC133 only defines modules up to 1GB capacity; so in order to have a full load of JEDEC compliant RAM in this machine, you'd need 32 slots for RAM!

Nowadays, the standards are evolving fast enough (in general) to keep up with customers' demands; if a memory type isn't fast enough or large enough, the manufacturers themselves meet & agree on a new standard that is.

If you're having trouble finding the answers you need in the Forum Search, this search on eBay's Reviews & Guides section will yield several useful primers on RAM selection:

In particular, I found the one by seller sbc_memory to be quite educational.

I'm sorry if the content seems a little dry; it IS a VERY technical subject and as such, it is pretty hard to make it interesting to those without the "geek gene". If you think they're bad, just try looking up the actual JEDEC standard documents for one of these memory types...
