Probably won't work unless you can also underclock the CPU with jumpers but what the heck, better than waiting a month :P

Yeah i cannot believe it! Thanks for the info. And again, thank you for all your input and knowledge about this. Will keep you posted when the HIP6004CB (What i think is the right  :-DD) Found a seller on ebay in china.

"1PCS HIP6004BCB HIP6004BCB-T SOP20 SMD Buck and Synchronous-Rectifier PWM
 $3.28 or Best Offer FREE Economy International Shipping" one also looks good

Probably will have to wait over a month again. Seem to be impossible to get hold of these in Europe?

20 year old highly time period specific (relevant for only ~3-4 years) chip, I would look for Slot1/socket370 motherboards with compatible chip at the scrap/local classifieds, or hotwire $3 "100W" chinese DC-DC module

Waiting a month doesn't seem so bad if it means getting exactly the correct part you need to fix your board.

I have run a 733MHz P3 underclocked to 533MHz on 1.25V (normal core voltage about 1.8V) for a pfSense router in order to reduce heat and power consumption, worked flawlessly for years until it was replaced with a newer system. (Quite a few pfSense builders back in the day did similar stuff, although undervolting was not very common.)

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

Yeah, that will also work. But i ordered "5PCS HIP6004CB Encapsulation:SOP" instead. Do have the exact (atleast in the title) as in the datasheet we used.

Yes you are right! And hopefully it will be the right part this time  :-DD

Thats cool, thanks for the input. Although tempting, i will just have to wait :-//
