Ram for Toshiba notebook A100-331
Hi, the differents sites for detection and the purchasing of
memories for notebook say that you can install 2Gb a slot for 4GB maximum (2slot) and instead *some rather 1Gb per slot.. Which one is reliable? Answer: that of Toshiba. But you cannot find my model because maybe now too outdated. Maybe with the upgrade of the bios can you get 4Gb as max memory? The system has Win XP installed. Thank you for your attention! -- sent from Android system phone - Rome, Italy ----Android NewsGroup Reader---- http://www.piaohong.tk/newsgroup |

The system has Win XP installed. Thank you for your attention! Pretty hard to guess without specs. T2300 Core Duo ? 945GM chipset ? You might be able to verify those, using CPU-Z program from cpuid.com . This picture, is a page out of the 945GM datasheet (Intel) http://i61.tinypic.com/2wfs1oz.gif It appears to be limited to 2x2GB, assuming there actually are two SODIMM sockets in the machine. Another physical limitation, is 945GM has only 32 bits of address on the FSB bus. Which is another way to prevent more than 4GB from being used. The processor has 36 bit addressing, but the chipset is only 32 bit. T2300 | 2x2GB --- 945GM | ICH7M http://ark.intel.com/inc/images/diagrams/diagram-5.gif There are still risks with this upgrade, in that you should be using Google to find examples of A100 owners with 4GB installed. The type of SODIMM I would expect to work, would look like this (16 chips total, double sided). Crucial is careful to hide their composition info, so we can't verify it via the Crucial site. http://img.rakuten.com/PIC/32403503/...0/32403503.jpg Some BIOS have a problem with the higher density modules, in that nobody "tuned" the memory parameters in the BIOS for them. I have an Asrock motherboard, where the hardware takes a 2GB DDR2 DIMM, but the BIOS is only tuned for 1GB DDR2. And the 2GB DDR2, when installed, makes errors. Therefore, I had to remove the 2GB DIMMs and not use them. So there is some risk involved, and you should find evidence at least one person got it to work correctly. http://img.rakuten.com/PIC/32403503/...0/32403503.jpg When I checked the Kingston (valueram.com) site, the 2GB DIMM specified looks like this. http://www.pcsuperstore.com/prod-img...3514-image.jpg Newegg has pictures of both sides of that module, and it is a 16 chip module. So I think this is the kind of module you'd be looking for. http://www.newegg.com/Product/Produc...82E16820134663 Crucial sells DDR2-667 CL=5 (CL = CAS Latency) in 2x2GB kit. So now all you have to do, is find an article about A100 with 4GB total installed, where the user knows how to test, and the unit is stable. HTH, Paul |

At link: https://www.dropbox.com/s/y9vntqv8xy...argh-ant_brett i-notbookToshiba.jpg you have informations about subjected notebook. The notebook is not mine but my friend is the owner. I'll tell him for CpuZ prog to identify the chipset. As you can check on my linked photo the cpu is T2050 at 1,60Ghz freq. I have just bought two banks of ram and the online seller has just secure that the ram (2x2) will work. I hope that it will be so to avoid useless shippings.. I remember i had an old desktop pc that cannot work without an upgrade of bios firmware for a more performance cpu.. I hope that now it will not be so for ram -- sent from Android system phone - Rome, Italy ----Android NewsGroup Reader---- http://www.piaohong.tk/newsgroup |
