Slim consoles don't use CPU_PLL_Bypass signal, and this fix works only for FAT consoles, which they glitch much much better then Slims even without any Fix

Usually the Jaspers I do glitch instantly without any fix applied at all.
the best you can do for a Slim to improve boot times, is to use a long wire on point A (CPU RESET) about 50cm and route it around the Fan itself and avoid any ground points, also the point B wire (POST signal) must avoid any ground points , use stranded wires on all points, use thick wires on VCC and Ground (Ground shortest possible) and clock wire/ point C shortest possible.
Another thing to consider is using higher Capacitor value between point A and ground (some Slims glitch well with the default 220pf, others need 270pf to work, and some few needs 330pf to glitch)
Good Luck.
