MP 1,1-5,1 4,1 flashed and chiped

[Puretexan2]

Wasn't going to flash my 4,1 to 5,1, but decided to anyway. Bought the cheapest Nvida Geforce GT 710 2GB. Bought two
chips on ebay, and went from 2.66ghz to 3.03 ghz. That worked perfect. I did use the squash your chips in the vice and delidded them.
I was going to clean the solder off like everyone does, but decided to pass on that. Worked perfect. So you can buy a cheap graphics card that has a boot screen and makes your flashed 5,1 metal. Also can stop wasting time scraping the old solder off your delidded chips .

Please post the temperatures in Celsius with MacsFanControl.

Doing a thing wrong and it works initially means not that it's right...

Ok wouldn't let me do a screenshot. a diode 40 a heatsink 39 a core 44 b diode 36 b heatsink 32 b core 38
Ambient 29.
Hope that is what you wanted.

I'm guessing that you think since I didn't remove the solder that was wrong. I saw posted in several places they said not to remove it because it was a good heat sink.

Thing is the solder will not be flat, and the best contact is silicon to thermal paste to heatsink, nice and flat. I have never seen flat solder after deliding a CPU. you are best to remove the solder from CPU.

Well me playing with these is just for fun. If it quits, there is another 2012 hooked up right behind me on another
desk. If it does mess up I would rip all the inside out and make a Apple Mac Pro cabinet to hold all my vaping stuff.
I really don't need two and they are cheap around here, so the loss of one really doesn't matter. It seems to be running
fine so far. I am glad ya'll are watching out for my best interest though.

Yet, the gaps and scratches are filled with paste. But that will wear over time.

Also the voltage regulators on the side will have worse contact.

The problem is that the CPU is too thick with the solder on. Too much pressure to the cpu sockets will bend them.

Even if I have a spare one I would not damage working hardware…

I'm not sure if I understand it correctly.
You didn't have to flash this graphic card to have the boot screen on your Mac.

You have to flash a 4,1 to 5,1 to use Mojave. Then you have to have a metal Graphic card. There is
a woman on you tube that said to use a cheap Nvidia Geforce Gt 710 2gb card. I paid $20 for mine used.
It will make your mac have the metal required. It also has a boot screen without having to be flashed. Then
Apple will download Mojave for free.

Thank you for the answer.

I have Mac Pro 2012 (Catalina) with GeForce 630 GT 2 GB from MacVidCards.

I'm not sure if it will the better graphic card than the current one.

The price is great and maybe I will have more luck with Mafia 3 for Mac.

 

[Puretexan2]

I'm not sure the card is that great for games . When you see one ,it looks like it should have come out of a box of Cracker Jack. It is not worth more than $20 tops. It will give you a boot screen and its plug and play nothing else.

 

[Puretexan2]

On my 2012 mac pro, I bought a Radeon RX560 and I think you could play a few games with it. That
one is $100 new and looks a little better built and also has a boot screen with no flashing. Plug and go.
Also will give you the metal designation apple wants for Mojave.

You got lucky on buying a used and already flashed card, PC cards doesn't have pre-boot configuration support with Mac Pro.

Humm the kid I bought it from was about 11 and I doubt that he had any idea how to flash anything.
My Radeon RX 560 was new in the box and it has a boot screen.

Seems you misunderstood what is considered "boot screen", having the progress bar midway loading macOS is not pre-boot configuration support.

Please read here:

An explicit definition of "boot screen" and its implications?

No GPU besides original Apple Mac Pro GPUs from 2008 to 2012 (HD 2600XT, 8800GT, Quadro FX 5600, GT120, HD 4870/5770/5870) or 3rd party Mac EFI cards like Sapphire HD 7950 Mac Edition, eVGA GTX 680 Mac Edition, NVIDIA Quadro 4000/K5000 Mac Edition or self-flashed/MVC flashed cards have what is...

Again, PC GPUs doesn't have pre-boot configuration support from factory.

Well there ya go. Tell that other guy so he won't buy one thinking it has something it doesn't, and I won't post anymore. See Ya!
