Phenom II x3 710 run with 4 core!
-
-
Looks interesting. My budget asks if I have $220-230 to spare. :p:
-
acc unlocks extra cores?
not bad... but... doesnt really boost performance, does it? :D
-
Unlocking cores that have been disabled sound like a very risky thing. I dont think AMD disabled them for fun...
Abit odd they aint lasercut or something tho.
-
how is this remotely possible??
i thought the disabled core was defective?
-
FFS this is a 125USD chip.
I'm probably gonna get one and a 790GX board to play with such fun stuff. Aww.

It might be or not be. if it is you gonna end up with alot of garbage data over time or just BSOD etc.

Err... these cores are not laser cut/fuseblown.
They are probably worse binned proper Deneb X4s that did not meet the 125W certification, and hence programmed soft to work as 3. Hence the almost similar power usage (the X3s with 4 cores would use extra power on top on that).
Keep it cool and nothing major should happen.
-
WTF? Its really possible :)?never seen it before.
-
I dunno. It all depends on how well the x3's are selling. If there is high demand for them there could be ones with perfectly good 4th core out there but usually the 4th core should be defective or at least unstable.

Why not? I don't imagine AMD is having that many quad-core Phenom II's crap out on one core to be able to supply the volume of tri-core cpus that are being sold.....they are quite inexpensive compared to the full quad-core cpus and appear to be selling pretty well.
So, AMD is probably pulling weaker PII's out, ones that would "just pass" qualification, and labeling them tri-core, in addition to using the "failed core" chips that started the whole tri-core thing.
-
lol. wow
can't wait to try this one ;D
-
howabout comparing wprimes.
-
Very interesting.
Is it Prime stable at 2.6GHz with all four cores?
-
-
Wow.. unlocking CPU cores--now that's new for me! I remember when the 6800 could be unlocked into a 6800GT with full 16 pipelines (now called TMU's). That was pretty much the last popular "unlockable", right? Oh yeah, and unlocking SLI on DFI NF4 Ultra-D motherboards...
-
where did owner buy the cpu?
-
Any first-hand witness besides the original news poster?

This sounds similar to when the 6800 series Nvicia cards were around. When Nvidia disabled 4 pixel pipes on the core to arrive at 12 on the vanilla version while the GT and Ultra had 16 pipes. Remember all the hoopla that surrounded the vanilla when it was discovered you can re-enable the other 4 pipes for more performance?
Now of course there was a chance that if you enabled the other 4 pipes it would cause the card to artifact or behave abnormally, but there were a lot of them that operated just fine after the 4 pipes were unlocked.
-
A user over at OCUK has done this although even at 1Ghz couldn't get all 4 cores prime stable

Still you have the chance to stay on older BIOS and be lucky to find stable enough X3 4core CPU. It will be a game like in good old times with R300 chips. Some of them were really defective, most of them were simply downgraded to Radeon 9500!
Now if they decide to fix that BIOS bug we need a good hacker to unlock this feature in newer BIOSes ;).

:ROTF: this is great :D
Brings back memories of gfx card soft pipe-unlocking :cool:

If a statement from an AMD marketing agent can be taken as real:
Quote:
"...The vast majority of the products we sell as triple-core are fused from the factory as triple-core from inception."
http://www.betanews.com/article/AMDs...ead/1234220042
If I make the following assumption -- AMD began tri-cores as a yield recovery mechanism, but are now intentionally disabling functioning cores. An assumption I do not know is valid, but assume it is...
This is the danger of bringing in the original tri-core concept, they are now disabling otherwise functional silicon as yields have improved. This makes for an expensive way to service a new market.
-
Good stuff. I've been running my x800 pro with all 16 pipes unlocked since day 1 and no problems with this card whatsoever. :D I wonder if I could get as lucky with this cpu!
-
I remember when I started to hear about more overclocking computer stuff, I heard about X800 being transformed into X850XT PE by a simple bios mod IIRC. Great times ^^

Most interesting. Wonder if you can buy the X3 black edition and unlock to a 940 black edition.

That is basicaly what is being done. It has all the L3 and all 4 cores if the 4th core is good, actualy would be a 945be tho. I bet AMD is kicking there selfs over this.

Yes !:up:

I have a feeling this whole core unlocking story is quietly approved by AMD.
It triggers much higher product demand from budget limited enthusiasts and this has domino effect on whole DIY market.
I'm tempted now to get X3 sooner than planned :p:
-
Well at least it confirms high yields.
This Mod is just awesome, put everyone tempted to just get one of these + 790GX/FX :D
-
well seems like it is possible with a x3 produced during the 4th calendar week 2009

Brings back memories of pencil modding 8500LE ... except you don't need a pencil! Also brings back memories of unlocking 4 extra pipes in a 6200 with riva tuner. This could be very interesting... at least fun to give it a try.

Good point on the 945BE versus 940BE. I doubt AMD would be kicking themselves over this, should result in a lot of positive press and secretly lets them release a chip that isn't truly ready for the market.

I have a feeling 945BE will be a new stepping. Of course press should now better :)

There no way that's happening, they are just 945 that didn't met the specs, either by a lot, no functional core, or by just a detail, hence the 4 cores 3.8ghz overclock with one cpu, and 4 cores at 1ghz that fail prime with another one.

Why couldn't you do this with the old phenom tri cores?

Well AMD ought to be making some profit on each of these chips sold, so the worst they're doing is driving up the sales of their chipsets and processors. Imagine if every Tom, *Richard*, and Harry went out and bought a 790GX board and an X3 710 or X3 720! They'd be "rolling" in new profits, and so long as one of these ordinary Joes can unlock his X3, they'll only sell more. And for those that can't unlock it? They'll still get what they paid for. For the cost of a 790GX and X3 710 ($200-230 in USA), you get a pretty good processor, a good board, and a lot of features that you can't find on similar $100 Intel boards (like CrossFire support, RAID, &c).
-
ROFL, very nice discovery :)
Maybe AMD left this Easter Egg for us?
Discrete Product Marketing any one?
any way, lets hope they leave all their X3's like this.
give us overclocks something to do :)

How have the overclocks and heat been on the regular 3 cores? If if failed QC to become an X4, then how do you know the 3 good cores you are spending money on are any good?

Because it's being sold. Very, very few Intel or AMD chips are ever DOA. The chips are binned so incredibly well that even degraded they can still exceed the needs of the consumer.

why is everyone assuming its a 945 that got cut? Why not a 925? They don't "make" 945s with an unlocked multi, its an afterthought.
For that matter, even as a 925 it may still have not made the cut, as the cpu may well have a higher TDP than required.
You simply can't tell for certain any of these cpu's we've seen are perfectly good quads.. yet. need more solid stability testing. not to mention power consumption
-
yeah these unlocked pitted against x4 940, x4 920, x4 810 etc on power consumption, stability and overall performance would be great.. also, people please save the current versions of bios on your motherboards!

True, which is why binning such as this exists. Some will be 100% error free, and just crippled to meet demand. Others will have severe issues, which will lead the end-user to just disable it again. It's still just a $120 chip and a $100-110 motherboard, and will provide a significant upgrade for a lot of people. And the enthusiast knows this and decides whether or not to try this. If it succeeds, free extra core. If it fails, you still got something fast.

Not to mention you still got craving for 4 cores, so sooner or later you will buy bigger brother X4 chip.
This is great marketing move, costly but great :up:
-
Does this work on the 720BE? That would be best, then you dont have to worry about the CPU bus speed as much. Better chance of getting a disabled core to run at proper speeds. Could down speed the bus and up the multi.
-
Should just go ahead and nickname this the gamblers chip lol. Very sweet though. I LOVE stuff like this.
-
as JJ has already said some amd tri cores are quad cores with one core disabled. if they didn't have enough cpus with one bad core they got fully functional quad cores and disabled a core to make a tri core. im not sure if you can actually enable them again but if you could some tri cores might actual be able to become quads since some of them have no problems.
-
Does this bios mod just work with phenom II and not phenom (1) X3?
And in that case, why?

True dat. And even if you get a quad-core without overclocking headroom, the people most inclined to do this (well, us!) would have the craving not just for a quad-core, but a fast quad-core. And thus the X4 925/945/&c will be coming in. So you have a 4-core X3 710, what's the point if it maxes out at 2._ GHz?

This does NOT work with phenom I AFAIK.

it shouldn't work with phenom II either and if it truly does i can gaurantee you that they would release a fix. either that or just stop making tri cores because all they are are a cheap way to get a quad.

Yes, they'll make a fix, but word's still out. Odds are Biostar will release a BIOS update, so don't update and should keep a quad-core on the cheap. If not, they'll keep it as it is, as a bonus for the DIY channel.
-
Is there any reports of this working on boards besides a biostar? I have a DFI JR 790GX sitting near me I was going to sell it, but if I can get a 720 and unlock it I'll have second thoughts.

Someone on OCUK was able to do it with an ASUS with 790FX and SB750.
You should get it anyway :) As long as your board has "Advanced Clock Calibration", it should work.

Well manual did not have it. Found out it was in there though. This is so tempting Newegg dropped their price down to 145 for the X3 -.-.

$119 and $144 as compared to $175 and $184 is hardly anything to get worked up over. BTW, do you get a cut on sales at AMD? I couldn't help but notice how you compared for better impact LOL! So we compare $119 to $175 = $56 then $144 to $184 = $40 Doesn't make much sense to compare the 2.6GHz to 2.8GHz since yes we know it costs more. 4 FULLY working cores should cost more as well.
In between getting flamed, I posted in the other thread that AMD would have some of the X3's that had all four cores working but one might have been slower, needed more power and etc... than the other three. Some of those X3s will have defective cores so folks buying them and thinking otherwise is kind of lame.

idk i was just looking at the fact that locked 710 is 56.99(have to get down to the pennies now because you can't tell a difference between 99 cents and 0 cents) cheaper than the locked 810 and both the chips run at 2.6ghz. close of a comparison as you can get for triple vs quad phenoms besides the fact that the 810 has a 4mb l3. and i compared the 720 to the 940 because they both happen to be unlocked although the 720 is only 2.8ghz. yes the 720 and the 920 both run at 2.8ghz but the 720 is unlocked and is am3. and where are you getting this 144 to 184 thing from? last time i checked the 720 is 145 and the 920 is 190. :confused: so i really don't know where you are getting your facts from but w/e. so if you think im trying to do some kind of trick to make the difference look much bigger you are wrong. don't know how you think you are getting flamed but w/e, and yes if this trick does work and you can turn on another core it isn't guaranteed to get you one because some cores work and were just downcored and some are bad cores and i would not recommend someone to get a 720 if they wanted to get a quad just because they could turn another one on. so just chill out when im trying to point of obvious facts, its not like im playing mind tricks.

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....

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 :)

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.........

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.

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.
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.

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.
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.
