I ordered a 2100+ from newegg... i thought all 2100+ were supposed to be green, but mine is brown.
i have tried many times to unlock it and change the multiplier with my 8k3a+, but it just results in no post. ONE time i managed a 14x multiplier (instead of default 13) but this was playing around with an LCD connector, and i set the multiplier LOWER than 13....
anyway i measure EVERY contact and EVERY trace with an Ohm meter. The resistance between the bottom L1 contacts and ground is 350 ohms.. the resistance between each bottom contact is 650ohms the top contacts had no connection at all.
after connecting the bottom contacts with the top contacts.. the top contacts then also had the 350 ohm to ground and 650ohm between them. I tested EVERY contact and there is NO short to ground, and NO short between them... i have redone it about 10 times.. and each time tested out good, but i still cant change the multiplier.
super glue was used to fill the gap, then rear window defrost repair kit to connect. then GOOP over the top to preserve the traces.
oh and when i refer to the bottom contact.. it is the row with the triangle.
anybody know whats up? the cuts were pretty small as you can see in the L3 and L4 bridges... dunno if that has anything to do with it.
