Can't get higher multiplier than 11.5 on Epox 8K7A using unlocked XP1600+ Please Help

[gnawrot]

Basically, I unlocked AMD XP 1600+ CPU and cannot get higher mulitplier than 11.5 and multiplier setting on mobo versus what I get is strange because mostly I get 9.5 than 11.5, 7.5, 5.5. I don't think that I am able to get any other multiplier. When I pushed FSB to 166 multiplier multiplier dropped from 11.5 to 9.5 by itself. I used unlocking kit on L1 bridges (kit sold at hardcorecooling). Cooling is not an issue because I have AX7 and YSTech variable speed 80mm fan (under stress temp is around 44 at XP1800+ after a whole night of encoding in TMPGEnc). This unlocked CPU was running at XP2000+ once but now I get this strange behaviour. Do I have to redo this L1 bridge mod because it could go bad with time? I guess this is the only explanation I can think off. Used newest BETA BIOS update for EPOX 8K7A.

Can anybody else help me please?

If you can only get 5.5, 7.5, 9.5, 11.5 on a default 10.5X 1600, then you have problems analyzed as follows.

10.5X has .5X, 1X, 2X, 4X Bit Values all set HI.

So inabilty to get 10.5X says that the 1X Bit Value circuit has been permanently reset LO, confirmed by the fact that all settings you do get do NOT require 1X to Be HI.

Then if you cannot get the integer Multipliers like 5X, 6X, 7X etc, then that says that you cannot reset the .5X default HI to LO.

Translates into this:-
1st, leftmost, .5X L1 is probably still open/not closed so bios can't affect change/turn .5X BV from default HI to LO.
2nd from left, 1X L1 is probably "directly grounded", which sets a permanent LO that can't be reset HI by bios.

It will be difficult to fix just those without disturbing the other 3 L1s, but try if you can.

PS If your kit was greasy conductive stuff, we'd recommend the rear window defogger repair kit stuff which dries hard...just be sure to clean the laser cuts first and refill with also hard drying insulating material.

Thank you very much for your very satisfying answer. I was not very eager to check L1 bridges because it is difficult to install AX7 in Epox 8K7A but I have no choice now. Yes, I was using conductive grease which is not permanent and now it seems that it not very reliable.
