The memory I've put in my iBook appears to have gone bad, it's only really surfaced when I've been compiling stuff and getting bus errors and other nasty sounding things. A quick run of Rember has revealed some rather extensive errors so I'm going to try taking advantage of Corsair's lifetime warranty. So I type www.corsair.co.uk and what do I see? A toiletries company, better try www.corsair.com instead.
