How much memory is "sufficient"?
Some yield tests
To illustrate the importance of the quantity of memory we have realized a few tests based on the suite Microsoft Office included with the program Winstone 99, centred not in the punctuation but in what more well-known the user: the time that is taken in doing the test (deducting the load in itself of the programs from the hard disk, for being independent from the quantity of installed memory).
Since it can be observed, from 96 MB scarcely change exists in the numbers, but to spend from 32 to 64 MB supposes an increase of the yield of neither more nor less than 42,5 %, and to spend from 64 to 128 MB an additional increase of 6,9 %. Bear in mind that this is a test, not the "real life", but anyway there is no doubt that to be employed with only 32 MB at Windows 98 is almost a madness.
An essential remark before throwing the bells to the flight and going out to buy memory: a memory EXCESS does not increase FOR ANYTHING the yield, only improvement will be appreciated if we needed more memory. So if it already has 48 MB or more and makes a use exclusively domestic or ofimático of the PC, he does not bother to install any more.
Advices and conclusions
Very well, it is already well of theories; let's go on to the action. If he is going to buy a new computer:
If it already has computer, this is a moment as good as any other an enlargement of the memory appears. Despite the fluctuations of last year, the current price continues well below 300 ptas/MB, what for the "elders" expert in these topics turns out to be the cheapest to us (in 1.992 it was to 5.000 ptas/MB). Bear in mind that:
Certainly, in "ancient" computers with grooves DIMM, generally Pentium MMX or the first Pentium II, often turns out to be problematic to install modern modules of memory of PC100 or PC133, for very diverse and controversial motives (size of the modules, number of faces of the same ones, speeds of access, specific incompatibilities of the chipset or the motherboard...). In these cases perhaps the best thing is to ask them to extend the memory in a shop where they give him guarantees, or to risk yourself. Sometimes the problem is solved simply changing memory mark or replacing the existing modules, but in other cases simply it is not solved...
To buy modules of second-hand memory (and/or to sell them), I recommend to him the bulletin boards or specializing web sites of Internet, as www.ibazar.es or www.mercadolibre.com; and if he wants to know more on the update of the memory, pulsate here to go to the corresponding paragraph.
In the future the tendency seems that it is not going to change: every time we will need more memory (Windows 2000 already "recommends" 64 MB and adds that any increase on this quantity will improve the yield), and it would not be strange that within one year the computers were coming like minimum with 128 MB, instead of 32. And that despite the famous phrase of Bill Gates in the beginning of the age PC: "nobody should need any more than 640 memory KB"... for the one that does not know it, 640 KB is neither more nor less than 0,625 MB.
