Hello all, I am I guess a I-Opener newbie considering I just got the thing about two weeks ago. So far I have added my own internal NIC via the 2nd USB port (a D-Link unit), added the Hdd mod kit from badflash, and popped in more ram. Now I am researching for the CPU upgrade to a K6 II/III(+) 450 and I have been reading through all the posts on the board for a couple of days, leaving me very frustrated and even more confused. Probably because my technical knowledge is not up to par with my saudering skills (got to thank PSX mod chips for that). Anyway I guess I will just fire away with the assortment of questions I haven't been able to find directions too. All I want to do is get a cpu running at 100mhz fsb at 450mhz. I can deal with the heat problem as I have knowledge with this from past R/C work.
I tried following along with Tackheads post:
but it looks like this is to only get a single Vcore at a time without resaudering or adding resistors. Or did I just completely miss something?
Also do I still only need 1 switch as in the V3 mod, or do I need the two, one for Vcore and one for FSB settings?
Also I know that the difference between the K6/II and K6/III is the extra cache, but what differentiates the + from the models? Would a regular K6/II and III still be comaptible with these mods?
I am obviously not an electrical engineer as it seems many of you guys are, is there any possibility of a dumbed down V1 mod instructions? I understand most of the current one, except what in the hell a "Pot" is and what it does, could someone clarify this for me, doe this replace the need for the Vcore switch?
As for the cooling problems on Q16, I have a couple of suggestions that should provide much more relief than the current L shaped copper solution Badflash proposed and other various solutions. My first idea is to use a copper strip about the width of Q16 and about 3-4" long, placing the strip dead in the middle of Q16. Connect with Thermal glue (If anyone can figure out how to keep it on without glue, then Arctic Silver compound would be MUUUCH better), and curl each end up and into itself zigzagging inward and then stick a true small heatsink on top of the surface the zigzags create. This should make for a fin type heatsink unit that should draw away much more heat than a regular copper strip.
My other idea is to simply bond a strip from Q16 onto the baseplate of the HSF unit for the cpu. I think this has the possibility to work even better but would require a heckuva lot more fiddling to work correctly.
One other possibility, although I dont know if they exist, is to simply bond a true small heatsink to Q16 and its surrounding area with a buttload of thermal epoxy. And if large enough add a small Video Card type fan to the top for added effect.
Thanks for any help you guys can give me, I really appreciate it all, this is one of the greatest home projects I have ever seen!
