Yesterday, I unlocked both of my XPs. My 1700 is doing fine, but I had a lot of trouble with my 1800. Didn't seem to work correctly, so I re-did the mod several times using Electro-Wash solvent to clean the L1 area and start over. After re-doing it the 1800 would only post at BIOS default of detect multiplier and would hang when I selected a multiplier in BIOS. I re-did it and now the 1800 won't post at all. Have tried it in two boards in which the 1700 runs fine.
I've examined the L1 area closely with 5x magnifying glass and I cannot find anything wrong. The trenches are "copper" colored now so I guess I exposed the underlying "mesh" (or whatever it is). The core is completey in tact, always used arctic silver compound, always used good heatsink when testing. Have examined all other bridges - they're clean.
I cannot find anything wrong with this chip yet it will not post on either of my boards. I'm wondering if exposure of the underlying copper in the ceramic has something to do with the chip not posting. Some of the L3 and L4 trenches look slightly copper, too, from the cleaning.
Shouldn't the chip boot even though these copper like trenches have had their original covering removed, or is that the problem?
I don't really think the chip is "gone" so I'm not ready to toss it in the trash.
Anyone have any ideas or suggestions?
