Finally the long story comes to the end. The designed VRM is working, the mainboard is prepared and I could finally do the tests I planned to do for so long. To be honest I didn't know what to expect initially, which outcome this results would have exactly and I hope, you will find them interesting as well. In this video I'm throwing all possible upgrades into Asus P/I-P55TP4XEG mainboard and with the help of my DIY voltage regulator I'm testing various CPUs (Pentium, MMX, K6, K6-2 and K6-3+) and cache types combinations. The results are IMHO very exciting and this is definitely not the end of this story line, not only I'm going to improve the VRM, but also in the future I'll test more mainboards and compare the results. Also I'm going to compare those to a Super Socket 7 mainboard to find out how a mainboard from 1995 would compete against one from the year 1999-2000.
