An EPYC Threadripper: Der8auer Gets EPYC CPU Working on X399 Motherboard

[lexluthermiester]

Same was said for BIOS flashing of pretty much everything and almost everyone does it these days...

You mean flashing a custom GPU firmware? Or updating a mobo bios?

I remember back in the day literally everyone modded R9500 to R9700. It was free unlock of texture units and you got a high end card from a mid end one. If money can be saved, people will do it.

I work with both TR and EPYC based platforms and I can tell you there is definitely more to this.

First off, there are specific pin differences that reference communication between different parts of the platform tropology..

by blocking the pin as he did, he simply stopped a hard fault condition. you could likely force a EPYC to perform a full bootup if you ousted specific pins but stability would likely be compromised as therte really is quite a difference between the two from a functional level especially in IMC.

Thats where a eprom flash would need to occur for stability reasons

Ah ok, gotcha. Heck I did that. Had one of the good ones that literally became a 9700Pro with just the FW flash. Needed a new HS/fan but otherwise run great for years. That was still an elitist/hobbyist thing. And what this article describes is a serious rigmarole.

EDIT; Fricken auto-correct. Always getting it wrong..

He is testing the possibility of getting an epyc stable in a TR platform, sort of like 771 xeons being used in 775 boards.

If he succeeds it opens the platform up to further upgrades, now if he figures out a multiplier hack there would be some sweet rigs out.

Oh, totally get what he's doing. It's interesting for sure. Just a heck of a process. The 771 CPU to 775 socket mod was a great example of just what can be done. Did it once with a C2Q 9775. It worked and is still running(AFAIK), but was a serious effort. But that was an extreme edition CPU the owner bought for a great price thinking he could just slap it in. So that mod was handy and saved his day. However, it was a very rare exception to the rule and happened after Intel had abandoned the socket/platform.

My original point was that AMD has nothing to worry about as this will likely never become mainstream.

Yeah only likes of myself would do such a mod lol

Exactly. People like us are hobbyist/elitists/tinkerers willing to give such an endevor a go because such things do not scare or intimidate. Like the guy in this article, we are the in the very small minority. Which is why folks come to people like us to solve problems most mainstream techs would scoff at. While I can't speak for you, it seems likely this applies.

The ePROM flash is not the end all tell all.... there are physical topology differences in the platform which have to be accounted for.

you can possibly "Make it work" but it would not be ideal by any means and likely from just a cursory look on my part of both platforms, there is a high likelihood you will lose core functionality if you get it to work at all.

Correct, and the same problem exists for the 771>775 mod. It will be interesting to see if this works.

 

[Punx223]

oh I definitely agree and Roman is a very good dude and a friend.... and he's quite intelligent with this...

I would love to see how it sorts out... I kinda wish I had time to allocate as I could potentially double the research effort on this... but I digress.... things to do.... (adulting sucks)

I know about bridging, it would need contact trace tape like 771 xeons did

It does apply, this kind of mod I would do, course there are times I just don't bother. @buildzoid does very insane franken-mods though.
