Hmm.. very interesting.. I have an AMD 720 right here.. and a few 790GX mobo.

So what are the exact steps I need to do to see if this works?

Drop one in and see if you have the Advanced Clock Calibration, set to auto, and reboot? That's it, I'm assuming. Then just test it--see if it's a reporting error or if there's actual functioning cores.

this is what people want. unlocking disabled cores, activating shaders etc. etc. good marketing from amd with taking no responsibilty

brilliant move by amd.... if a large percentage run error free this could be very profitable for them....

modify Advance Clock Calibration to Auto :rolleyes:

This is cool...
Let's get real though. How many people will actually learn about this? Then, of those, how many will splurge on hoping everything works out fine?

You'll see a very small percentage, but nothing significant.

If I was looking to make a new build, I would see how much success everyone else is having, and possibly make a go at this myself though! Like I said, this IS cool :)

If TDP is the reason they are converting those quads to triple cores why cant AMD sell those as Quads with a bigger TDP for the same price ?

No. Its mainly due to physical defects in the logic.

ok. so the extra core might cause more harm than good huh

Could you show us the official AMD doc that says so or are you just making this one up like you often do?

of course he does!! It's called FUD!

don't agree... this'll make X3 extremely popular against competitors Duals, it'll help mobo partners sell more SB750 mainboards, it'll create differentiation in AMDs portfolio, artificial yes, but still economical reasonable... if equation don't bring profit they can always swap those X3s with upcoming Propus, that will obviously meet well developed manufacturing process and high yields

Unless they make a massive TDP failure they would be sold as X4. Or the other option is that AMD canibalizes itself and sells X4 as X3. But thats pretty much suicide tactics. It would be cheaper just to sell X4s discounted to an OEM instead.

If things are too good to be true. Then they usually are. The person that couldnt get it prime stable at any speed is a good example.

Sure you can find some that will work. But you also find alot that doesnt. And what error you might get from these refurbed cores is pretty much up in the air.

Board Makers Confirmed Phenom II X3 Unlocking

http://resources.vr-zone.com//upload...20_to_X4_1.jpg

Quote:

Yesterday, a user posted an interesting piece of discovery in our forums and that had prompted enthusiasts to try for themselves. Till now, several users have reported success with the unlocking of the Phenom II X3 processors. To verify those claims, board makers too had done some internal testings and so far achieve some success as well. Above is test done on the DFI 790FX board and similar success stories are reported from the labs from Biostar, Gigabyte and others as well.

From what we know, only 0904 batches of Phenom II X3 can be unlocked. Basically, it just uses ACC core to trick the CPU to enable 4th core that has been classed unstable by AMD. However, not all unlocked Phenom II X3 will be stable so you will need some luck here.

Phenom II X3 processors are selling in the States for US$150 and if you wish to get locally in Singapore, the only place you can find them are in Cybermind, retailing for S$246. Last checked their batch is 0904BPMW.........

Now this is a much better way of saying what the different possibilities could be ;)

very interesting, I love these things that can be unlocked,
I had a 9500np running with 8 pipelines, and 6800le with 12 or 16 :)

Because motherboards weren't build for that, now they un-officially let you run 4 cores but if the disabled one was defective or needed more power they wont get hurt by this. Also if it needed more TDP and the motherboard cant handle that and blows up, the only guilty one is the user;)

Im sure there's quite some good working disabled cores, however it ain't guaranteed.

Although somehow I think there might be just a BIOS bug, this certainly might boost sales if the majority of the triple cores works flawless with 4 cores. If the bug would be removed (aka, it was unwanted), pretty sure there will be some modded BIOS's.

I'm in for more info. I have the right stepping in my 720 (0904cpmw) but no 790 board yet but could see myself buying a new board today if the numbers are true and it's stable.

If the motherboard manufacturer did not build their board with appropriate headroom there is no way it would live for very long without failure anyways.

Certain unlockable video cards come to mind.

where to find AMD Phenom MSR registers Prorgammers Guide? Setting up definite bit(bits) in definite MSR register will give us a key to how to unlock fourth core

If I remember correctly, it's somewhere in the BIOS developer's guide.
The problem is that you need to reset the processor after writing the registers to enable or disable a core. And that means you would have to reboot the system, so the defaults of the BIOS will be overwritten into the CPU itself anyway.
I'm not sure about this, but I think it's worth a shot. We need to look into this.

Very nice side step. But had you paid close attention, you'd see I was speaking UP for AMD, not trashing them. You wouldn't know a fact if it bit you on the @$S:rofl: Again, I'd said I mentioned this on another thread. Still got jumped by AMD Fans. Here's that post I was talking about and look at the thread's Date?

For instance a Dual Core@2.8 Costs more than a Quad Core at 2.2GHz. After binning the Quad Core AMD finds that 2 cores will only do 2.2GHz and the other 2 does 2.8 or better, sure AMD will kill the two slower cores and sell it as a 2.8GHz Dual Core. Wouldn't you?

I think folks want to be able to overclock each core independently because they know one or two of those cores might just be screamers. I agree with them.

Now please show what's wrong with that post?

Not sure about Core i7 (never heard of it mentioned alongside with this feature), but K10 is probably the first desktop CPU to have full multiplier control over cores.

So it doesn't matter that much if your X4 has a lame core. Clock the rest up, let that one stay at 3.3Ghz etc.
