MacPro2,1 with ATI Radeon HD 4890 fan issue

[onesixright]

Hi All,

// MacPro2,1 Quad Core Intel Xeon (3.0)

Some time ago I installed a ATI Radeon HD 4890 (PowerColor), it works fine. Only the fan drives me crazy. Just a simple Safari visit and (while scrolling up/down) the fan goes waaaay up, making that annoying sound fan. One of the things i love(d) on my MacPro was that with the X1900 it was always silent, now with the knew card its utterly frustrating.

its that bad, i rather use my MB Air, then my macpro...

Anyone that has a 4870 installed, do you guys also have this same fan issue? Anything i can do? Or should i install a new card? I'm almost ready to get my old X1900 back.....

Any (other) card that does work fine, including fan, connections, etc.?

Help appreciated!

Is the card an official Apple card which is under warranty?

Apple does not sell 4890's.



Get a PC 6870.

OK, thats a answer, its a card from the Apple Store, or can i take "any" card and flash it?

Thats a AppleStore -> MC742ZM/A ? do all the ports work?

Thanks!!

As Cindori stated it did not come from an Apple store.

Have a look at this link:-

Hi, thanks. But thats related to the 4890, i already have one and i know you can't buy it @ Apple's. My question is about the 5770 (Etherz10 post) is this the card from Apple (MC742ZM/A)

And does it all work....?

 

[Cindori]

yes
yes
yes


but really, PC 6870 is much cheaper, much faster, and also works out of the box.

Are you saying any PC 6870 should work? or only a specific brand?

I was looking at the: Club3D HD6870 ? So that should work then?

Thanks!

ye, in lion

Cool I'm running Lio, you said any brand right? So the
Sapphire Radeon HD6870 - 1GB - PCI-E
(the other card was out of stock) Should work?

One more question about the power, i have 2 cables going to the 4890,do you know if i can use these same power cables? Or anything else i need to order?

 

[Cindori]

yeye, plug n play. same cablorz.

might be worth noting you won't get bootscreen atm. since it aint flashable (for 2.1mp), yet

out of the box, steam and dvd players doesnt work, to fix,

ok, super thanks for the quick reply! I go order 2night.

By the way, i get a access denied on the link when downloading the package (webpage loads, but download link doesn't).

When you say 'works out of the box', do you mean also works with all video outputs (specially two dvi with two monitors at the same time) without applying nothing ?

I'll use it on a MacPro 3.1 (2008)

thanks

ok, so I must be doing something really stupid, as I can see everywhere that a 6870 should work as is on a MacPro wiht Lion, but not mine ...

The instructions are very simple, if you have an extra power cable with the card, connect it. This card has two sockets for plugin an extra power, but there's only one cable that fits in the card that has two power connectors.

Those two connectors are connected to the Dvd power and the extra power, but the screen is black, and the card has always a red light.

What I'm missing ?

thanks

One power cable. You need two of this kind: https://forums.macrumors.com/posts/13020536/

This is what I thought, but in the card there's only ONE cable, that is splitted in two, I thought maybe was the same or a new model ...

In the card instructions just say plug this power cable in the card, and in the picture there's two plugs and just one cable plugged.

I'll try to arrange another cable and see ...

thanks

It's PC card and nowadays any ATX PSU has at least one line for PCI Express.

 

[Cindori]

and the card must be in bottom slot, it will run like crap at 8x PCIe 1.0

Hi Cindori,

Thanks, got my card, running perfectly. With a Dell U2711 Indeed the DVD player is crashing, well got the files. The access denied has to do with the country your downloading from.

Thanks!

Thanks for your replies, finally I've created a Hackintosh i7 and I'm using with it, all works great and smoothly

Thanks!
