BP_FID , have they been disabled by AMD?

[Slappy5]

Just finally got around to reading Anands article on Duron OC'ing way back when, and he had expressed concern about AMD disbling the four BP_FID pins effectively (as far as I can tell) curbing all oc'ing attempts... any word on this, because I am have a HELL of a time co'ing my Duron 750 on my MSI K7TPro2a, even with adequate cooling and silver epoxied (er..) l1 jumpers I cannot go past 750. I can UNDERCLOCK, as in set the multiplier below my rated spec of 750, so I know it is unlocked, but I get that infamous funky jumper thing that underclocks when I try to over clock. Any thoughts?

afternoon bump... this is kind of funny

You sure you made the right connections and no connections touched that shouldn't?

Erase all of the pencil marks on the cpu and do it again. AMD did not disable anything. It would be all over the internet by now. I have done a bunch and never had a problem. Even the newer AMD chips are not disabled. I have seen lots of people here that had to repencil several times to get it right. good luck!

Well, I actually used silver based epoxy and it didn't appear that I crossed any jumpers when I applied it. I guess I'll take a closer look. But isn't it odd that I can accuretly and successfully underclock the chip? Help?

um are you talking about arctic silver adhesive? Um I dont think it is conductive, you might get a capacitive effect, but I don't think it is. Go to Checker Auto parts and get the rear window defogger repair kit and use that stuff. Or just use a pencil.

"From Arctic Silver's site"
Negligible electrical conductivity.
Arctic Silver Thermal Adhesive was formulated to conduct heat, not electricity.

Even though Arctic Silver Thermal Adhesive is specifically engineered for high electrical resistance, it should be keep away from electrical traces, pins, and leads. The cured adhesive is slightly capacitive and could potentially cause problems if it bridged two close-proximity electrical paths.

Not sure if Silver based Epoxy is any good. The Loctite 15067 Defogger Grid Repair kit is the best to use when connecting bridges.

ok, hmm... I'm still a bit confused as to why a I can change my multiplier at all if I hadn't done it correctly (afterall, it does underclock like a champ!) As for the arcitc silver, by all means i did not use that for connecting the jumpers

IS there perhaps a way to hardwire some pins or do I perhaps need to fiddle with the other multipliers on the chip, ie L6 etc?

Thanks for you replies, I really need the input here.
