Methinks you are exaggerating When's the last time you complained about Paul exaggerating? Here are some links: Neither 845 nor 850 based motherboards are safe. The same risk may apply to nForce based boards. All other boards (including all AMD and VIA based boards) are safe from this problem.We were merrily completing our new Intel i845-based 1.8 GHz Pentium 4 test system when we flipped the switch on the power supply and the system came on instantly -- which should not have happened. Too late. The smell of ozone was already wafting in the air, turning our stomachs. Our new i845 system was dead. vanshardware.com Current popular chipsets like Intel i815, VIA KT133(A), KT266(A), AMD 760(MP) etc. are supporting both AGP working voltages of 1.5 and 3.3V, whereas motherboards based on Intel's i845 or i850 chipset and nVIDIA's forthcoming nForce are unable to work with 3.3V graphic boards, absolutely requiring an 1.5V AGP graphic board for avoiding damage of both mother- and graphic board. For the same purpose it is compulsory to use only AGP4x slots on the concerned motherboards, yet applying to all available i845, i850 and nForce motherboards according to our present knowledge. Unfortunately some manufacturers put AGP2x graphic boards with AGP4x-shaped plugs on the market, therefore fitting into AGP4x coded slots. This should be no problem as long as these graphic boards provide a signaling level of 1.5 Volt or are solely used in motherboards with the above listed 1.5/3.3V-compatible chipsets. But exactly this seems not be ensured in all cases, as there was feedback from motherboard manufacturers and users as well, informing about hardware damage after plugging such a graphic board into an i845 motherboard and therewith providing the basis of our article. hardtecs4u.com
