ati radeon hd 4870 mac pro 2009 4.1

Eirikstrand1996

i have a radeon hd 4879 for the mac pro 2009 4.1 model, but 3 of the capacitors are broken and i need new ones. but i dont know the number / value of them. kinda need a service manual or something, or someone with det same card can  send me a picture. I can not install the os on the mac without the right card

If you can, take a picture of the card and I'll do my best to tell you what you should use. The card may be  a "reference design" that's sold under other brand names and it may be easy to figure out what was used.

 

if the cards are pci express, then if they're near the pci-e 6/8 pin connector , most likely you'd have to use 270uF or 330uF or 470uF 16v polymer capacitors. For input power into the card, the exact capacitance value doesn't matter that much.

If they're somewhere else, probably 560.. 820uF 4v or 6.3v rated polymer capacitors but really can't be sure, don't take what I say as correct.  Here the actual capacitance does matter a lot.

Those are all on 12v , so you should use 16v rated capacitors.

Based on other similar layouts i see on Google , 68uF 16v polymer (solid) capacitors seems to be the right choice.

It will probably work just fine with 100uF or 150uF though.

Surface mount capacitors would be ideal but you could also use capacitors with leads and just bend leads and solder them to those pads.

keep leads as short as possible, it matters.

Personally just throw another card in that machine. It's unlikely that any modern MacOS has support for that card. Get a 5770 or any card that has been in any mac since.

No you don't. If you make a bootable USB it will just run off the USB as it's the only thing that is bootable unless you have partitions on the hard drive that work.

Why are you trying to install snow leopard? Also Mac will not let you run an old version of mac installer on a newer version.

dont think the mac pro 2009 can run sierra, but i think it can run snow leopard. what do u mean with: ''mac will not let you run an old verson of mac installer'' ? i got the mac from an it guy i know from my college without a harddrive so i bought a new ssd

Yes the 09 Mac Pro can run sierra. Just needs to be flashed to be a 5,1 instead of a 4,1. The reason it was crossed out is because it is an older installer than the current OS so mac won't let you run it.

Try installing sierra onto the hard drive after applying that hack and then putting the hard drive into the machine. That should also boot.

sierra wont work on 2009 mac pro.
