I really do not understand.
Before you say
but then you (correctly) state
So which one is it?
If Pixlas' mod is carried out correctly, with the correct cables, exc it is a
MUCH safer way than try to overload the mini6 pins of the motherboard until one finds the power limit.
If then we take into account extreme situations (e.g. a Fury X running furmark), well then obviously either way might still not be 100% safe. But Pixlas Mod would still be safer (if one made some basic math about the power consumption of his cMP.)
Funnily enough, I read a thread not long ago, of a person having a Titan Xp shutting down his/her mac.
And then it turns out he/she was running it with the mini 6 pins(!)
So
obviously it shut down.
I don't think I really understand how people can't see the risks of powering a TDP>225W graphic card with the mini 6 pins - and on top of that, there are other people actually starting threads misleading others into thinking it's OKAY.
Let me repeat (for the others, I know
you know), it's
NOT safe, and not okay. The fact some cMP user haven't experienced shutdowns
does not make something unsafe, safe.
As I see it, only Pixlas mod or an external PSU are the solutions to 1-2 GPUs with TDP>225W.
What is the official correct way to carry out the Pixlas mod? NONE!
Draw more from the 6 pin if OFFICALLY outside limit. But REAL WORLD proven can work flawlessly. (Same as Pixlas mod, if carry out correctly! e.g. Only draw <100W on any 6pin, but not go >120W)
Overload directly from the 6pin port is unsafe? But overload the wire behind the 6pin port is safe? They are still the same wires! Apple never ever OFFICALLY says where is the 75W bottleneck coming from. How do you know it's not the wire?
A TitanXP can shutdown the Mac, because there is a shutdown PROTECTION! Running the GPU without protection is safer? The shutdown proved 2 things.
1) the GPU draw too much
2) the protection works
Think this way, Intel CPU has thermal shutdown protection. If the CPU overhear, the computer shutdown. Is it safer to disable this protection (assume we can) and let the CPU keep running even overheat? Please think about what is "protection". Plxlas mod effectively bypass the shutdown protection only gives out more flexibility, but not make it safer. It's the other side indeed.
You put a GPU that outside the officials limit is NEVER safe. Bypass the protection won't make it safer.
My point is, NONE of those 3 methods are safe OFFICALLY, but all the them are proven safe to use in REAL WORLD (fact). You can pick the Pixlas mod and believe that's the safest. But that subjective (opinion). There is simply zero evidence to prove that any of these 3 work around is safer than the others objectively (fact).
May I make it clear. I am not arguing that overload the mini 6 pin is safer than Pixlas mod. But it work (if do it correctly). However. Pixlas mod is also not safer than overload the mini 6pin. But it also work (if do it correctly).
Either options has their own limit and concern. And ALL of them are not safe officially. NONE of them are OK officially.
Is delid safer than use washer when upgrade the dual processors 4,1 CPU. For the socket, delid is safer. For the CPU, washer is safer. That's is, none of them are officially safe.
We discuss lots of unofficial hardware upgrade / mod in this forum. And most of them are proven OK in real world. Is that means safe? Obviously NO (officially). But it's up to the user to accept the risk of not.
Is dual X5690 safe? NO (officially), but we know it works (real world proven).
Overload the 6pin is not good to the port, or to the logic board trace. But won't physically damage the wire (from PSU). And no need to touch the PSU.
Pixlas mod will physically damage the wire (just under control, it actually cuts the wire a bit). Or required soldering on the PSU. But safe for the logic board trace (simply don't use it).
Protential physical damage to the wire or PSU is safer than protential overload the port or trace? They simply cannot be compared directly!
It's just the users opinion to decide which one is safer (that's the users personal opinion, but not a fact).
