Re: [LIB] Max Memory Question
Date: Sat, 19 Oct 2002 09:00:01 -0400 From: Gennadiy Tsygan [EMAIL PROTECTED] Subject: Re: [LIB] Max Memory Question I did some research on the memory question, and found the chipset used in Libretto 100/110 is the same as in other Toshiba notebooks with more memory. So I decided to try to replace chips on the upgrade module with higher capacity ones and see what happens. Then I found out, that high density EDO chips- needed to have 64 MB on 4 chips, are very hard to find and expensive. When I learned that my experiment will cost more then $350, and outcome is very uncertain, I decided to direct my energy elsewhere. The only component level performance upgrade available for Libretto is overclocking by changing bus frequency multiplier on CPU. When I had L100, I tried to overclock it by changing the bus speed itself, but it refused to work at 75 MHz. - Original Message - From: Lawrence Fieman [EMAIL PROTECTED] To: Libretto [EMAIL PROTECTED] Sent: Friday, October 18, 2002 8:38 AM Subject: Re: [LIB] Max Memory Question Date: Fri, 18 Oct 2002 08:30:54 -0400 From: Lawrence Fieman [EMAIL PROTECTED] Subject: Re: [LIB] Max Memory Question What restricts maximum memory? Why does a 50 or a 70 Max out at 32mb, while the 100 and 110 max out at 64mb? It seems that the workaround for this must be far too much trouble and expense. Otherwise I'd see more postings about upgrading maximum memory.

Otherwise I'd see more postings about upgrading maximum memory. Much as it'll be nice to be able to do this, you're not the first person to have asked this on this list ... unfortunately, it doesn't seem to be possible (or at least that's been the conclusion of previous discussions on the topic). Certainly the physical memory modules weren't produced in any bigger than 16MB for the 50/70 and 32MB for the 100/110 (which of course add to the 16 or 32 already on-board). Given that the system would not have been produced with the ability to add more RAM in mind, it would seem doubtful that even IF a way of adding more RAM was found, that things like suspend-to-RAM and suspend-to-disk would work without some BIOS hacking (which then brings the problem of where to get documentation on the BIOS ... apparently *someone* managed to get some info to get the FDD working under Linux but we've heard nothing further on that lead). Then there is the other problem of where to get the RAM chips required and how to manufacture a board of suitable dimensions. It's highly doubtful that you could just unsolder the existing chips and replace them with larger ones like you can with less advanced electronics such as graphics calculators and Palm organizers unfortunately :-/ Of course, I'm always hopeful to be proved wrong here, 64MB is *alright* for my L100 but more would be nice ;-) - Raymond --- /~\ | | Does fuzzy logic tickle?| | ___ | My HDD has no reverse.

Re: [LIB] Max Memory Question
Date: Fri, 18 Oct 2002 13:11:36 -0700 (PDT) From: David Chien [EMAIL PROTECTED] Subject: Re: [LIB] Max Memory Question 1) available parts . laptops were designed for xx max ram depending on what's available then. thus, the latest 1GB memory modules weren't in mind for the Libretto way back then. 2) space economy. 3) whatever the designer suggests. -- I'm sure that if someone traces the memory lines all the way through the machine and does a few low level tests, he'd find out if there's enough memory lines to support bigger,custom modules. but nobody's done that yet, so we're stuck with whatever we have. even if the HW supports bigger ram, the memory layout of the bios/machine may not, and that maybe something else you can't get around... still, it's worth a try just to see what'll happen... eg.the Libretto ff1100 can go to 96mb ram vs. the almost the same L110 at 64MB, so there suggests that the difference was simply availability of ram modules that were of high enough density. = adorable toshiba libretto The latest news and information for the Toshiba Libretto owner. http://www.silverace.com/libretto/ __ Do you Yahoo!?
