Pirs CPU has NOT been unlocked from the factory. And whatever happend, no clear signs are visible from the outside of CPU. BTW he tried another CPU in his MB and it was NOT unlocked.Quote:

You wrote no clear signs.. How do we know?.. have anyone else looked at the cpu besides pirs? It could be some small metal piece which you will need a magnifying glass to see.. it could also be visible under the IHS aswell if there´s something that happened there...
Anyway, we´re here to figure out how to unlock this baby :toast:
OKQuote:

i meant CLEAR signs ... if you need a magnifying glass it is NOT a clear sign :)
pirs told me he looked at his CPU numerous times and he couldn't see anything unusual.
Has anyone tried measure the fx series cpu and compared it to a non fx cpu??
It may not be as easy perhaps..
If we say that we compare these two and find no differences, then there propably is a pin which either isnt connected or theres two pins connected which in turn fools the cpu thinking that its unlocked? (on pirs cpu that is)
Dam.n.. if we just had pirs cpu so we could do some serious testing :(
Another thing we could try is to connect some pins..
To do that we need someone who can take a look at the amd cpu pinout diagram and see which one´s that doesnt make the cpu burn out :p
If we try connecting two by two then eventually we may break the code :banana:
An easy way to do this is to have an ordinary cpu cooler and have the motherboard outside of the case and simply solder on the backside of the motherboards cpu socket pins.. thats way much faster than fiddling with the wire trick..
Inputs?
YESSSSS!!!!!! :banana: :banana: :banana: :banana: :banana: :banana: :banana: :banana: :toast: :party:Quote:

didnt we go over this a few pages back?
the multiplier is set on die correct? and the FID_STATUS and MAX_FID comparison happens on die, so pinouts are useless in this little situation right? except for attemting to program FID_STATUS the bios has no effect on multipliers. At least thats how it reads in the 939 func data sheet. or are we trying to mess up that comparison by shorting out the circut that makes it?
Yes but think again.. do you really think that pirs cpu was programmed??Quote:

As i believe that something has been connected on pirs cpu somehow or a pin which is loose.. but i rather believe in that some pins are connected..
yeah that makes sense, did he ever try it in a different MB, i mean i know he tried it with a different proc, damm thats alot of work....Quote:

Pirs has some extraordinary luck i reckon...i wish some of it would fly over my way to Australia once in a blue moon :D

wel all pitch in $10, he would sell it
I'd be willing to toss 10 dollars into a hat to get a shot on unlocking all A64's
~Mike
i could scrounge up 10 bucks,
but anyone who gives money should hands down get the solution first and at no cost, not that i really think that that would be a problem here, but its happened before.
I see us (tndb) going over a lot of ground already covered... but he may have a point, sort of. We (ok, everyone else on here, I've just been keeping an eye on this thread) have done our homework,and found that athlon64's cannot just be reprogrammed by bios or software to become an fx. The only logical way to do that is to do what tin_eof is trying / going to try to do, and that's that whole jtag stuff (way over my head). But we overlooked one point, and thats because we are approaching this from a logical viewpoint (as well we should).
What if a bit of static discharge killed a couple of transistors or something, which (luckily) didnt kill the chip, but (even more luckily) messed up the whole FID_STATUS and MAX_FID comparison process. Random, yes. Bloody impossible to work out how to do that deliberately, yes. What I am saying is, despite the fact that the chips are designed not to easily unlock multipliers by the whole MAX_FID thing, that's only if that part of the cpu is in tact and functioning properly. Its behaviour when damaged would be unpredictable.
But for us hopeful overclockers, tin_eof's approach is the best step forward for now, as his way will be reproducible.
Is it possible that JTAG way will be able to much more things than unlocked multiplier?
e.g. make CPU think it is an FX, unlock locked cache and core...?
I'm thinking he works for AMD... :stick:Quote:

oh i am not opposed to pitching in $10 to help try to buy it.
but only thing is who gets the cpu? i would think it would need to be someone who is well respected and knows how to not kill the cpu while taking off the ihs and has a big magnifing glass. just my oppinon but it should go to a moderator that lives in the uk and he can then make the choice of where it should go if his measures fail at uncovering the unlockability.
I was kidding :p: but you can't tell me it's not kinda fishy that he's ]thaaaat lucky with the CPU he gets.Quote:

And that reasonable price comes too...$650. I'd sell it for that, at least :D.
The CPU is still For Sale here on XS. I'm hoping someone interested in this research will buy it... but if you want to do it do it while it is still available...! and PM me.
Hi to all.. I isolated each of NC pins one by one...but nothing happens. CPU still locked and working :).
Prueg I think the same way.
Damn, If I have enough money this time I would take pirs's CPU. But... ^(
By JTAG it is possible to change ANY register. So you can rename CPU, cut cache off, change CPUID, disable/enable features. But it is not possible to make FX57 from Venice :) It physically have 512K L2 only :) And more bad process... :) But except overclock power and cache size it's possible to make FX57 from Venice :)
Of course I'm not sure, But it is clear that this will be true..
Waiting for hardware from you :)....
P.S. I'm currently benching my Venice E3 3000+ at 2750MHz 1.8V (ICE Watercooled). Nothing changes. The speed the same. A little faster than FX55
P.P.S. Now I'm rebuilding my DD PC to -25C Chiller.
Ok, isolating the pins does nothing obvisually :(
My next thought which is a far more dangerous step is short circuiting pins, which could be any pin really..
Say, if pirs got something conductive on the cpu when it was laying between the ashtray and when he then mounted the cpu, the cpu got short circuited when he booted his computer and the venice was unlocked..
Ive described the easiest way to short circuit the pins (which I mentioned in earlier post) solder on the backside of the mobo.
But at the same time.. It could be about just any pin..
Isnt there a pin described in the amd sheet which is used for multi? maybe that one :P or not.. Well I dunno anymore, the jtag stuff is out of my area but keep researching.. We could possibly do other things with the jtag programming.
Doesnt pirs live in czech?
thats the area where the chyrnobyl cloud was, want it"?
maybe its readioation? :P
