Apparently some lucky dude has stumbled upon an "unlocked" Venice 3000+ :hap2:
More here: http://www.xtremesystems.org/forums/showthread.php?t=71723

However what is interesting is on the last few pages. The folks there are trying to figure out how to get all A64s unlocked.
Quoting someone there:
Okay, people. You want guide to unlock your A64 ?
Listen here.

It is simple.

1. take JTAG programmator. (most low-cost selfmade if 5$)
2. take PDF for JTAG implementation in A64 CPU (if you have any - send to me )
3. put cpu to programmator, poweron, flash register C0010042 and C0010041 with data from FX-57.
4. Enjoy your free-multi cpu.

dude please tell it in normal english, so that noobs like me can understand , How the hell do we unlock it? i dint get it, plzzz eddy simple dumbies guide to unlocking a64 plzzzzzz!!!!!!!!!!!!!
 
I'm not good at explaining this, but from what I know - A JTAG interface started out as an interface on electronic components for testing the components.

However JTAG is mostly used for programming/debugging the chips. A lot of CPUs including AMD's chips include this JTAG port as well. The basic idea is through the JTAG interface with suitable JTAG programming equipment, you can play around with the CPU's registers. Play around with the CPU registers and you can change multipliers ;)

The process isnt complete though, as I mentioned the folks are still working on it
 
so, is it similar to flashing the internal bios of cpu or smthin, in plain jane english, and what is a pdf to jtag converter ???????????, NO idea ? plz expalin and i had heard such similar things for athlon xps mostly barton cores where they used to short the pins on the cpu, and unlock all the multipliers, to that extent 1 of friends told me that on lamington road too, lot of such overclocked chips were unearthed, even on semprons ppl used to unlock the 512kb cache by some graphite pencil shorting method or smthin, so in that case if this can be done easily , why companies arent doling(like u get from bfg versions of card where they are overclocked) out such tweaked venice processors where the multipliers are unlocked, it will be a huge market , or this aint possible, practically though??????
 
Its not legal. AMD will not allow anyone to market such CPUs. It will be illegal. Yes you can do it for your own processor. But no company will be allowed to market such CPUs.
 
Definately not worth the risk. I had read this before on Wired and they said its very very risky (1/10 chance of unlocking, and 8/10 chance of ruining it).

Basically you have to reprogramme the registers on the CPU as Eddy said, which hold a small bit of info (like a miniature BIOS) but the catch is, once you fail you cannot restore it.

Also even unlocked CPU's face lots of stabiliity problems as they arent designed to run at those multiplier settings.

The article even said that if you manage to unlock the multi, many a times the mobo doesn't recognise the CPU thus rendering it useless again...

afaik we, are not reverse engineering the processor architecture,just tweaking the processor to extract that maximum juice, it will just void the warranty because here u own the processor once its sold to u, and unlike software it aint licensed where we need the rights given to u are not the whole proprietary rights, the licensee agreement here is

only relating to damges claim and any warranty related claims, which amd will surely abrogate of such tweaked processors, as far as u dont reverse engineer or come up with a product which has claims based on amd patents, i dont think there is any hassle, even if it goes to court amd has a lame case out here, as u arent licensed the technology on some terms and condition but sold it, theres a differnce between licensing and selling as far as proprietaryship is concerned....,,,by the way its a good contest if someone really comes out with such tweaks.

i feel it will still depend upon the firmware license or the internal bios licensee as here the tweaking firm will have to come up with something original and not fx series firmwares or smthin as the software is sure licensed

Good question, I dont have a clue. I guess people who are regularly working with embedded hardware like ARM processors and the likes would know.

What the guy meant was he wanted a PDF file showing the JTAG implementation in an A64. That would help him to play around with the registers.

The earlier AthlonXP's are completely different from the Athlon64s as per unlocking multis - those just had bridges to enable/disable multipliers. For the Athlon64 and later AthlonXP's its been "super-locked", the locking has been done inside the CPU core itself. Which is why playing with these CPU registers could offer a chance to unlock them.

AFAIK, there are companies like Alienware that market systems with OC'ed CPUs. Some dealers offer hand-picked steppings of CPU's that are known to OC well. But unlocking a multiplier and selling it as a higher rated CPU, is not legal. People were falling prey to it with the earlier AthlonXPs. Slower speed CPU's were OC'ed and sold as higher rated ones, and that is not acceptable.

A link to the Wired article would be good :)

I believe with the JTAG interface, you can play around even with "dead" CPUs. So I dont see how you cannot restore it should it fail. In fact the guy at XS who has offered to try it out, is working on dead CPUs ;)
 
No, Eddy it wasnt online it was in March 2005 issue of Wired. My uncle got me a copy from the states...

dude but u missing the point the companies wont be fleecing the customers by overclocking the cpus, they will be offering unlocked cpus ;) , and not overclocked 1s, so theres a major difference ,u see, and wheres funky dude , seems like ultimately i have hit upon a good idea , lets start a firm where we sell
cpus with mobo combo and ur oc wizardry and sell it off ,,,like alien ware ,;)

i sell lotta green here........,:cool2:
 
@Viking

It is illegal to sell CPUs with unlocked multis when the manufacturer has locked the multis. If you unlock the multis on a 3000, then who will buy a 3200 or a 3500?? It does not make business sense. And that is why they lock the multis.

And if you commercially sell the unlocked multi CPUs, it is illegal;.

Which law says that??????????
even if it does say,its highly contentious issue, as far as
monoploy and restrictive trade practices law is concerned.

I agree u cannot tinker around with software as u dont own it,as its only licensed, and i also agree that if i reverse engineer the product then it will infringe their patent as far as commercial exploitation is concerned, but if i tweak around the processor which i fully own (its not licensed but u are buying the propertiorship from amd of that piece of silicon)without the reverse engineering, or wrongfully using their software, (considering their software is copyrighted or patented otherwise, cud even use their software without any legal claims) there is no illegitimacy around?

Yes, agreed that amd will not offer me warranty claims then but , they cant stop someone from selling it with multipliers unlocked, as its only a better use of their product which has been found out, but even then as this is highly interesting, i will ask 1 of my law prof. (if they do understand any of the stuff ;) ) .

As to whether and what law works behind this rationale, if dc can do with modded cars , why not with proccy?

Fine dude.... go ahead and sell unlocked multis.

Dont count on us to help you out if you are sued or arrested. I am not wasting any more server space trying to convince you.

U getting it all Wrongo, dude, first if theres a procedure to unlock the processors , many fellas wud have dun it successfully and then even sold it,
the thing is that ,if u feel its acrime please show me the law which says so???

And i am pretty sure theres no such law, but as ignorance is bliss, there might be, but always support ur arguments with proper sources,or logical reasoning, dont give subjective judgements, if u come up with good logical reasoning or sources(bankable sources) to support ur claim then , why not i be convinced,
i really dont wanna get arrested hey ;)(howsoever i wont be as this ,,if at all is proved a crime, this is a civil crime and not a crimal crime so no arrests atleast till the indian courts prove it, and even if they prove it ,it wud take years and the result will be damages[punitive fine]only, so no arrests)

Yeah,,,to comeback to the topic so, i was thus tring to say that if there are no legal complications involved , and if its "REALLY POSSIBLE" to unlock the venices, companies sud take advantage of this ......????

As, ur logic goes, u say why wud then ppl buy 3500+ or 4000+, hmmn well u can unlock these same to higher potential and lemme confirm this from some ip professionals if there is any law which specifically doesnt allow, unlocking of chips>>>>>>>>> thats the reason niks if u give me a good logical argument with somethin to back it up , i will surely call it, In ur say, but u givin me no reasonings,........

And jus JUDGEMENTS ,, if u get somethin substantial to prove, it will , hear ur
call and respect it.......
 
Simple things.

You can do whatever you want to with your CPU.

As long as its for personal use its fine.

Processor is piece of hardware. But the technology still belongs to the manufacturer. You can mod it for your personal use. No issues there. You only loose warranty.

But you cannot mod it and sell it to make profit. Thats why few months ago police raided some places in ASIA where Axps were sold after modding multiplier and sold as different CPU.

Its just that you cannot use it to make commercial profit. The technology behind it is still AMD or Intel property. They have the right to stop you from doing that for commercial use. For personal use you are free to do whatever you want.

AFA 3000+ goes, many 0518 3000+ were unlocked upto 11 multiplier.

It is legal to sell unlocked CPUs if you sell it as unlocked and make clear that AMDs warrent is void!

It is illegal to sell unlocked CPUs as a different faster and more expensive model like them in ASIA did!

Damn the law is so easy to understand, why all that fuzzel?
