cadavecaDidn't AMD say that they DIDN'T use non-functional dies, and the non-working dies were just spacers without any transistors? Or was this more BS by sites that AMD should have never supported? :p ROFL :kookoo:

I wonder what would happen if you stuck a TR CPU in an EPYC board? Would there possibly be a way to enable those "EPYC Failures"??

:slap:


:laugh:


:roll:

gdallskSockets are electrically different, so if you actually tried it wouldn't work.

cadavecaAre we sure about that? I'd be willing to try... :p

gdallskYeah, AMD said so themselves, the layout of the pins might be the same, but the roles could be switched... but you're welcome to wreck a 1k dollar CPU and god knows how expensive the motherboard is :roll:

Red_Machine"Sir, why did you destroy a one thousand dollar CPU?"

"FOR SCIENCE!"

btarunrPC enthusiast Der8auer, with access to a Ryzen Threadripper processor, took it completely apart for science. It won't be the first time that a Threadripper HEDT processor was de-lidded (its integrated heatspreader removed), revealing that it has four "Zeppelin" 8-core dies, making it practically identical to AMD's 32-core Epyc processors; however, it's the first time that someone completely removed the dies from the package.

Ryzen Threadripper processors are built by completely disabling two out of four "Zeppelin" dies on an Epyc multi-chip module (MCM). Two diagonally opposite dies are disabled. The disabled dies can't be reenabled, at least not on an X399 chipset motherboard, as the Threadripper HEDT platform lacks DRAM, PCIe, and possibly even power wiring for the disabled dies.

VSGAMD's phrasing was that these two dies were non-functional, with transistors that did not work. It remains true here as well, but was vague enough to where some had misinterpreted it, including me.

SlizzoIt was my understanding that in statements from AMD that two of the "dies" were blank silicon to even out pressure on the heat spreader, and two dies were actual Ryzen dies?

OSdevrAFAIK AMD always referred to them as "disabled" but many people (myself included) thought they were just blank. I thought yields were over 50% so why would you throw away good dies when you could just use spacers?

theoneandonlymrkIt was a partner and not Amd that said they were packing, if i recall right pc world, AMD did exactly as i thought they would and im sure i poo pood the two space filler dies comments then.
It's simply the most economical and practical solution, build test bin , drag out of bin invent consumer line.

OSdevrUnpackaged dies can be tested these days. If they didn't HBM would have a miserable yield before ever being attached to a GPU. Remember that supposedly only the top 5% of Ryzen dies go into TR.

GoldenXWouldn't it be great if we could return to the Phenom II days and unlock them?

theoneandonlymrkI know ,They could always be tested to a degree , in reality their will be several check stages during production and packaging each presenting a new binning opportunity.
My last line was mild satire, or a try at it.

nemesis.ieI'm sure CaseKing sponsored him rather than it coming out of his own pocket, trade price at least.

newtekie1I'm pretty sure the CPU was already dead. In his original TH de-lidding video he said that the CPU did not survive the de-lidding process. So I'm guessing he used that dead CPU.

And he wasn't intending to kill the CPU when he did the original de-lidding, it was unfortunate that it died.
