Only I know for real which one is which. You have a 50% chance of guessing. I'll give results another time. One of those 2 chips is a Ryzen 3 1200 and the Other is Ryzen 7 2700x. They L@@k Identical. I found it quite interesting!!  |

It's the one on the left; looks like it had indium on it and the Ryzen 3 1200 from memory uses thermal paste under the IHS.

Ryzen 3 on the left, 2700X on the right.

It's the one on the left; looks like it had indium on it and the Ryzen 3 1200 from memory uses thermal paste under the IHS. Both chips where soldered. The one on the left had the solder scraped off but hadnt been lapped yet. The Ryzen Athlon 200 and 220GE with Vega graphics are not soldered however. |

2700 on the right. Too many hints. One on the left is unlapped, and the 2700 was the first you delidded so I assume you lapped that right after completion.  Didn't even need the picture. |

Yes the one on the right is in fact the 2700x processor.
I had expected a difference between the 1st and 2nd Gen Ryzen processors and obviously they are the same.
We can see the 1200 is a Octo-core processor and has 4 cores and SMT disabled.
Imagine we could alter Agesa code and activate some cores or SMT hmmm....

Interesting good if it does unlock weather its 100% stable though is a different story.

Well I don't have the slightest idea how I'd go about doing it. When install the 1200, SMT options in bios dissapear. XFR also gone. This chip doesn't "boost" either. It will manually overclock thankfully for that AMD.
So really it's the firmware on the processor that commands bios. There's probably no chance for an unlock.
They do not have different physical features either. I gotta get a high powered light and possibly a microscope to see through the PCB for cut tracings....would be one way to look for physical differences.

Thanks Eddie. When I pull the HTPC out for spring cleaning, the Ryzen 1400 will be next. That processor is the same as the 1200 with SMT enabled. I have a feeling it will look exactly like the two I've already popped the tops on.

Yeah all the Ryzen chips are basically the same die but with parts disabled, bar ofc the APUs.

Its a crying shame AMD did away with core unlocking. Think of all the possibilities lost... The core unlocking was on the motherboard side of things. ACC or advanced clock calibration was meant for fine tuning an overclock or in correlation of, but it wound up being the go to setting for unlocking cores. So the Agesa code in modern chips is likely what prevents a core unlock as you would also see XFR setting removed in bios when using a processor that is not equipped with SMT or x core count. Other than that, the processors look exactly the same physically aside from Athlons and APU series chips. I do wish unlocking was available.... It would be sweet! |

But ACC was an AMD technology, not developed by the motherboard manufacturer. AMD knew ACC could be used to unlock cores. They did away with that functionality with Ryzen, that's all I'm saying.

Gotcha. It would be nice to unlock, but then again, they won't make sales of the bigger unlocked chips at higher prices I guess. AMD needs the loot. After 2020, we'll be looking at 5nm AMD Ryzen 4 chips.

Core unlocking was a side effect of Advanced Core Calibration. It was not the intended function.
When AMD was hurting for production, they filled orders with bigger processors than what was actually called for. They just disabled cores, damaged or not, via code instead of laser cutting them like they do now. You will never unlock again.

I remember unlocking well. You know this chip Scotty. Phenom II 565BE. Man that was such a sweet chip. It got beat to hell and back XD Here's x2 unlocked to x4. That thing would cruise at 4.4ghz all day no problem.  |

What do you mean when you say laser cutting? I've never heard of this term before. |

AMD never advertised unlocking processors. Doesn't matter if they advertised it or not, fact remains they created the technology to unlock cores in the first place. All I'm saying is its a shame AMD did away with core unlocking on FX and Ryzen, would have made for some very unique processors. |

AMD created the code to lock cores. Somebody, either internal or hired by a board manufacturer, reverse engineered the code and wrote a piece of hybrid firmware to unlock those cores. AMD had absolutely nothing to do with it. I believe the first manufacturer with an unlocking board out was Gigabyte. They had an option in the bios, under the ACC tab , to use either standard or hybrid firmware. When you chose Hybrid, that's when cores were unlocked. It wasn't even really a piece of ACC. After that, all the major players had boards out that unlocked.. |

It's all good. AMD loses money every time somebody unlocks a cheap CPU into a bigger more expensive model. No company would do that intentionally. That's why when AMD disables cores now, they disable them mechanically on the CPU by laser cutting them. No code brings back mechanical damage. |

Lol, every body was like wow back when these where released. Super hype. I remember seeing images from Asia of unlockers while we waited for release in the US.
It was a very fun platform 100%. The phenom II's did ok under LN2 and dice also.

If You can change pin layout on a 1151 board with a beta bios so a newer gen cpu becomes workable, we still have some hope to cure laser cutted parts ! :DDDD (troll off) |

The core unlocking was just amazing, couldn't believe it when they allowed us to do that. It took budget performance to an all new level. Would have been cool to see it live on, but alas its not the case. Its even funnier that two of the people who helped me clock that chip are sitting in the thread directly above me on another site!  |
