So I thought I'm relatively save, not overheating the P90. And I think this is the only thing that might happen, when overclocking a chip. Ok, the CPU works perfectly with 75 MHz, It made 2 make worlds and now I was supping -current the whole night long without problems. Can I assume, that the CPU should be completely damaged at any frequency, when I had overheated it ??? So that it's more likely, that the L2 burst cache is buggy ??? At what speed is the cache driven ?? Same as CPU speed ? Or has is the same base frequency as the oscillator (50,60,66 MHz) ??? I think base*something (1.5,2.0,...). The problem is, that a friend of mine has the problem, what to give back to his distributor, we don't want to have much trouble with his dealer .... Are there test programs available for the 2nd level cache .... Perhaps souns silly since this is not the kind of memory, one has directly access to ... But perhaps someone has a good idea, how to find out precisely, what's damaged and what not. Ok, I could start asking people, to give my their working P90 for a weekend ... but I don't know someone who could .... -- $$ apsfilter - magic print filter 4lpd @home : andreas@knobel.gun.de $$ ftp://sunsite.unc.edu @work : andreas@sunny.wup.de $$ /pub/Linux/system/Printing/aps-491.tgz knobel: >>> powered by FreeBSD <<<
