Ah, I just re-read your mail and then re-read my motherboard manual. So I'm running with an effective fsb of 66.8MHz [penny] That's what I get with the default settings of JP29 & JP23 on the motherboard [duh] If I was to jumper them at, say 5-6 & 3-4 respectively, this would give me host clock 3x (100 - 124MHz) [er] which I assume would then show up in the BIOS? [oh] could I then set it to the specified 100MHz x 6 ?:-] I assume that's what my system would prefer. [ps] One day I might get the hang of this hardware stuff. [clunk] I realise this is probably elementary stuff for most of you. It's a flippin' revelation for me :-) Little note for Steve Harris: If I'm right, this means I've been successfully running JAMin on a severely _underclocked_ Celeron 600, so stick that in your minimum system requirements ;-] thanks for your patience & assistance. tim hall Last Saturday 24 July 2004 01:42, I went: > Last Friday 23 July 2004 22:32, Rick B was like: > > ? ? ? ?Yes, I would think that you would notice a big difference.
