Hi all,
I have Toshiba Portege R205. It came with standard with 512MB dual channel RAM. I want to change the 2GB Kingston module to it RAM, . I want to know that it is supported or not. So, what do you guys suggest ? I am using windows XP on it. Thanks in advance.
As the notebook memory expansion slot by the restrictions should therefore be chosen as large capacity memory upgrade. Capacity caused by the different speed memory embodiment may vary greatly, and this will directly affect the performance of the system. Because the reason notebook computers are smaller, generally reserved for the 1-2 expansion memory slot, and most of 2005 after the sale of notebook computers have a slot in which the plug a memory, And because the location of the slot by the need to disassemble the whole arrangement after the panel, so they do not take into account the warranty period, the principles of removable, the average consumer can not change his. Therefore, we can leave only one upgrade slot, if they can support 1GB capacity, which should never buy a 512MB. :biggrin:
Notebook PC makers for the stability of the machine or its own business interests, generally upgrade the memory requirements are more demanding, and some only recognize its own memory, and some books will not correctly identify a high capacity particles will plug the memory point is not on there machine, or capacity issues such as recognition errors. This is usually said that compatibility is not good, but the memory itself is not the problem, might change to other models on all OK. But with the gradual unification notebook architecture and open standards, the current situation has much improved, many of which are a common. All the best. :biggrin:
From the power consumption and heat dissipation aspects to consider, the fewer chips notebook products more conducive to the stability of a long run. Compared with the same capacity memory, if the more advanced packaging technology used, then the memory chips may be less than other products, it also simplifies the external PCB circuit board, reducing energy waste memory for notebook long-term use offers some help. At the same time, due to different capacity memory chips not very different from their own power, so a higher capacity memory chip and even less energy consumption, which means that the heat generated by smaller, more conducive to the stability of laptop time run.
Toshiba Notebook memory upgrade in capacity, on how how much it better? This notebook itself, according to the constraints and your application needs. Notebook memory constraints are mainly reflected in two aspects: the maximum capacity constraints and to effectively manage capacity constraints. Most models also on the maximum capacity of a single memory restrictions, specific instructions to view the machines, but some older models can be broadened by refreshing the BIOS limitations. For notebook memory is not the bigger the better, if the blind pursuit of high-capacity machine will only result in waste or shut out, which we must pay attention. :rofl_2:
According to the original Toshiba notebooks that have to use the memory frequency set, for example, a DDR2-533 memory and a DDR2-400 memory with, for the former is a waste. If you want to have replaced the original memory DDR2-533, and will have to see whether the system supports the external bus frequency, which is determined by the board, rather than memory (generally not recommended overclocking), If motherboard does not support, there is no need for memory, and a waste of money. Select the original memory frequency standard line, also help to ensure system stability. For memory latency, we use the CAS Latency (CL) to measure.
