I thought i found something, binding it to the "cheaper" cpus but according to other peoples experiences it just seems to spread over all alpha systems, just some have it and some don't. some less and some more. no common denominator to be found so far. I played with the machines for weeks and months and just couldn't find anything pointing in any real direction. nothing reliable. looks like everybody was banging it's head against that stuff for years and nothing worked so far... just turned them off after some time, had other things to do and was better for my electricity bill. ;) -sm
