Well, the use of the adapter is certainly essential in motherboards with linear voltage regulators, I think that in that case selecting 6X or 400MHz, it would be quite hot, perhaps hot, the problem would not exist with switching regulators, from experience the linear ones without adequate cooling can create problems already at 200MHz, while with switching it goes smoothly at 450MHz and probably even beyond.
I don't know what MB you use, but a k6-450 can be easily installed in almost all MB S7 (not super), if they don't support the required 2.2V, several can generate voltages lower than 2.8V, usually 2.4V or 2.5V , but in case the minimum was 2.8V a simple modification could be made to lower the voltage to about 2.2V, it's not a modification I've ever done but I believe it is possible to get that voltage using one or two diodes.
Unfortunately I am not a technician but I know that these changes or other similar ones have been made in the past, unfortunately not all cards are the same, so the change must be made specifically for the card, afterwards if you have the right voltage, you have to understand if the BIOS recognizes the CPU correctly, if it is not recognized, you need to make a change to the BIOS.
Unfortunately I can no longer find the sites where there were the modifications for the socket7 VCore.
