Hi. A friend has brought me a P166 which gives a lot of problems. It is the typical PC sold in Spain (in fact, most PC's sold here are so), since after opening it, I saw the following: -The mobo is the one known as the "cheap $69 Houston mobo". -The mobo has no cache (although can be added with cache on a card). Well, at least it is not "fake" cache, but much slowness for little savings and much ignorance. -The Pentium is clearly fake (surely a P150). In fact, the ceramic is more reduced than others I've seen, and unequally (2.76 to 2.77 mm; original is 2.80): you can see it is thinner in some areas than in others. IMPP mark on beneath. -The memory is garbage. The chips are CW416804-6 (unknown manufacturer). They have a label "made in Taiwan". It should be known that there are only 10-12 reliable memory chip manufacturers. -The disk is bigfoot type (5.25"). It should not cause problems, but is very slow. -The CD is Cyber, which has a high failure rate. As seen, it only misses the fake cache soldered on mobo. This is what is the typical clone sold in Spain; I'm courious about what is found in the US and other countries. What I will do is put good memory, and if that does not work, I'll aditionally reduce processor speed to 2.5x60=150. ************************************ Javier Vizcaino. Ability Electronics.
