Can I install TWO HD 4870 cards in my Mac Pro?

Please can you help?
I've just bought an 8-core 2.66 Mac Pro and two Radeon HD 4870 graphics cards, but each card requires two power cables to connect to the logic board, which has only two connectors. Does anyone know where the two cables to the second card should go? The second card works fine, but I expect the cables are for the cooling fans, so I don't want to fry the second card!

It's just that I have bought two new Apple LED displays (with Mini-DVI connectors), and of course there's only one Mini-DVI port on the HD 4870, hence the reason why I bought two cards. I can't find a Mini-DVI to DVI adaptor anywhere for the second port on the same card,
You need a DVI to Mini DisplayPort converter. There are a couple available now:

does the GT120 also require a power supply from the logic board?
No.

HT4628 I can not use the internal wireless card with my Mac pro 2012, I don't know if it is broken

I can not use the internal wireless card with my Mac pro 2012, I don't know if it is broken. The problem is happen recently, I have to use an independent wireless card now. Thanks!

When you enable Internet Sharing in OS X, you are creating a separate sub-net.
There is no option to allow this to be a simple pass-through from Ethernet to AirPort (or the other way).
The problem is easily solved by getting an inexpensive wireless router. You can replace your current router OR disable the DHCP server on the wireless router and allow the wireless clients to get an IP address from the current router.

Can I install a Netgear pc card in a mac?

I got a netgear super G notebook network card. Can I install it in the card slot in my titanium powerbook? I already have airport installed inside the powerbook, but it's 802.11B as opposed to the faster G.

Maybe depending on which model Netgear card you have.
You will need to use the third party Orangeware Wireless Driver.

How can I install Windows7 -64BIT on a 1st Generation Mac Pro 2.66GHZ Quad?

Hi,
I posted this in Bootcamp but haven't received any replies so I am reposting it here where perhaps it really belongs.Is it possible to install Windows 7 64 bit on a 1st Generation Mac Pro 2.66Ghz?
Apple suggests that it's not possible and yet I've seen several Googled posts where the users have successfully installed 64 bit on a 1st Generation Mac Pro. The problem is that they've done this creating a bootable iso disk(whatever that is) using a Windows computer with imgburn and windows commands. I'm pretty good at following instructions but I haven't seen any instructions on how to install Windows 7 on this machine using a Mac based approach.
I'm using BootCamp and was able to partition the drive into NFTS and "proceed" with installation; however all the installations failed during setup and Windows would not boot; disk repair was not possible. Besides, from what I've gathered, 32 bit is problematic around memory issues.
When I try installing 64 bits, I never get past the "select cd rom 1 or 2" message where the keyboard won't work. It is at this point where others say they have successfully proceeded with moving forward by creating a bootable iso disk.
Problem is it's all Windows based with exe files and presupposes I already have Windows running.
I'm not sure I really understand how to create an iso disk, but I do have ROXIO TOAST 10 which is capable of burning "ISO" disks.Does anyone know how to do this and/or can you point me to a place where there are instructions on how to proceed?? While I realize Apple says that some mid 2006 mac pros aren't supported, there are multiple posts of windows 7 users successfully installing Windows 7 on a 1st Generation Mac Pro.
Thanks.
Mac Pro 2.66GHZ Quad Core

I have a March 2009 Mac Pro dual quad core running Win7 Pro 64 bit. I have Windows installed on a dedicated internal hard drive. There are no partitions, the entire drive is for Windows use.
Here's how I installed it, I did not start with BootCamp. Make sure the drive you're going to use for Windows doesn't have any important files on it because it will be formatted.
1. Update Snow Leopard
2. Place the Windows cd in the Super Drive
3. Shut down the computer
4. Remove all the hard drives except the one you want Windows installed on. Keep track of the order they are in and at the end replace them in the same order.
5. Boot the computer holding down the Option key
6. Boot to the Windows cd
7. Install Windows and format the drive to NTFS
8. When Windows needs to restart during installation you'll need to hold the Option key and boot to Windows, not the Windows cd.
9. After Windows installs, place your Snow Leopard disc in the Super Drive
10. The Drivers for Windows will be installed along with a Windows version of BootCamp.
11. Go to Start > All Programs > Apple Software Update
12. Update again until it's done.
13. You'll also find a BootCamp under Control Panel, check it out.
14. Shut down the computer and replace the hard drives in their original order
14. Now if you turn on the computer it will boot to Snow Leopard, but if you hold the Option key during boot you can select Windows or Mac.

How can i install again the audio card of my mac,

it doesn't work I don't know why... yesterday it was perfectly fine

You can not install iOS 5. It is no longer signed by Apple. You can only install the current version of iOS. For a 3GS, that's 6.1.3.
However... if you have 4.2.1 on your phone, odds are it is not a 3GS, it is a 3G. If that's the case, you've reached the end of the road for that. It can not run anything higher than 4.2.1.

Top two best video cards for older Mac Pros?

I have some older Mac Pro towers that vary from:
2.66 GHz Quad Core Intel Xeon
..to this:
2 x 2.93 GHz 6 Core Intel Xeon
Looking for at least the top two video cards that are tried and tested that would work best with at least Premiere Pro and AME. I just need to narrow down the unwieldy list that can be found here: http://www.adobe.com/products/premiere/tech-specs.html

Are you adverse to using aftermarket cards that have been converted to work properly in a Mac? If you aren't, then I'd recommend talking to Dave @ MacVidCards because he can cook you up an nVidia 700-series card that will boot properly in a Mac Pro, run at PCI-E 2.0 speeds, and work wonderfully in Pr/AME.

Can I install SATA6 drive in my early 2009 Mac Pro

I want to add an internal hard drive to my Mac Pro. Most of what I'm finding with the speed I want are now SATA6. My manual says to use SATA III. Can I use a SATA6 drive in my early 2009 Mac Pro?

Can I use a [6Gbits/sec SATA-3] drive in a 2009 Mac-Pro
Executive summary: Most regular commercially-available drives you buy new today will install and work fine. It IS worthwhile to pay extra for a drive with a bigger buffer, but do not pay EXTRA for SATA-3 alone, it is all specsmanship.
If you buy a weird older drive, or you have a really old Mac, it may not work properly. [WD Raptors and VelociRaptors work fine.]
RE: SATA Bus speed:
Rotating drives available today, whatever their SATA spec, can source data off the spinning platters no faster than about 125MBytes/sec.
SATA 3 is rated at 6G bits/sec, which theoretically is about 750 Mega Bytes/sec
SATA 2 is rated at 3G bits/sec, which is theoretically about 375 Mega Bytes/sec
SATA 1 is rated at 1.5G bits/sec, which is theoretically about 187.5 Meg Bytes/sec
None of the SATA Busses is a bottleneck for consumer Rotating drives you can buy today. Trying to speed up the SATA Bus will not provide any real-world performance increases for Rotating Drives.
Even most common SSD drives are not bottlenecked by SATA 2.
If you put the drives on a PCIe card, they are not bottlenecked by the SATA on the card either, as it will typically be SATA 3.
But unless you have the very fastest SATA drives available, you are in no danger of having the existing main SATA 2 Bus in your Mac Pro slow you down. The card is only needed for the fastest SSD drives available today, and will not provide much current speed improvement even in that case.

Can I install a Lacie D2 Drive in my Mac Pro

newbie question, sorry!
I have a Lacie D2 500 gig external drive that has crapped out on me. I was told that it could be possible that the enclosure is the problem and not the drive itself. If I take the drive out of its enclosure can I install it in one of the Bays in the mac pro?
thanks

It could just be the dead/defective power adapter Lacie seems to be a known for. Before you crack the drive open, i would strongly recommend that you test it with a known, working power adapter. Perhaps a friend with the same drive? If you're lucky, i've seen some of the Lacie drives set up in Apple Retail Stores, and perhaps an employee might let you test your drive there. Worst case scenario, you could order a new adapter which will set you back $19.00.

Can I install the ddr2 pc5300 memory from my Mac Pro 1,1 in a Mac Pro 3,1 that requires ddr2 pc6400?

I have replaced a Mac Pro 1,1 with a used Mac Pro 3,1. I am trying to canibalize as much as I can. Will the slower RAM from the 1,1 work in the 3,1? Dare I just stick it in and try, or might I cause damage?

I don't quite understand. I do plan to try installing the old ddr2 pc5300 667 from my Mac Pro 1,1 into my Mac Pro 3,1 one pair at a time, just to confirm each pair is in working order and happy in its new home. I have 8x2 GB of RAM I hope to move.
I am uncertain what you have said from there. Yes, the cost would be cheap, free in fact! Is this what you meant? You had suggested buying 667 from Amazon, or similar -- but I don't need. And you have made the point that 8 DIMMs is beneficial--which I will have covered. (great tip)
I think what I am most uncertain about is the comment about what will run cooler. Maybe you mean if I purchased newer memory, the design has become more efficient, so the expense is worth considering?
Thanks in advance!

Can't install my Mountain Lion again on my Mac Pro -- help please.

I can't install Mountain Lion again on my Mac Pro: got this message: This copy of the Install OS X Mountain Lion application can't be verified. It may have been corrupted or tampered with during downloading. Delete this copy of the application, and go to apple store ...

Well, the hard disk has been replaced and the Apple people replaced but innstalled the older OS (
X Lion 10.7)! So I tried to reinstall the newer OS which from App Store under Purchases but I had the problem I stated earlier: This copy of the Install OS X Mountain Lion application can't be verified. It may have been corrupted or tampered with during downloading. Delete this copy of the application, and go to apple store ... Hopefully, I can get this fixed! thanks!

Can't install OSX 10.7 Lion on old Mac Pro...

i've got an old mac pro... i think it is 2007 or 2008 vintage... it is the 2.66mghzzz model...
it is so old it can't run OSx 10.8 and up... so I am stuck running 10.7xxx
anyway, system disk died recently...
made an OSX 10.7 install thingy on a 8gb USB drive using my new Macbook Pro...
problem is the install keeps hanging after starting the install... i've attached screenshots showing how far it gets...
i've let it sit for a few hours and no progress... i reckon it should normally finish installing of a USB stick in maybe 30 minutes or so?
is it possible that the 4tb SSHD drive i am installing onto is too big for this machine?
it has been using other 4tb drives so not sure this is an issue?
really stuck here... argh...
thanks

thanks for your reply...
yes, I realize it will only install on older macs... my Mac Pro is the 1,1 model... the 2.66mhz processor is from the 2006-2008 era....
i believe it shipped with 10.4 or 10.5 OSX...
it was previously running 10.7.5 which is the newest OSX that was allowed to be installed on it....
so it should allow 10.7 to be installed? Or do I have to start with the much older osx?
I downloaded Lion 10.7 from the mac app store and it of course wouldn't let me install it on anything, even the 4tb SSHD drive when I connected it via USB/SATA adapter to macbook pro as it is too old for running 10.7 install on this machine but I was apple to use SuperDuper app to make a boot drive of the 10.7 download form the mac app store onto a 8gb USB flash drive and make it bootable...
The 4tb SSHD drive appears to work on system as I can run disk utility and format it and mount it etc etc...
Perhaps there is something wrong with my install USB flash drive I made? I am really stuck here...
thanks for your help...

Installing GeForce 8800GT Graphics Card in Early Mac Pro

When I install the NVIDIA GeForce 8800 GT card, is it necessary (or desirable) to remove the existing graphics card that came with the Mac Pro?

If you have 10.5.6, that is all you need or available under OS X all graphic drivers - outside of the rare "Graphics Update 1.0" are bundled. I actually hoped we would also see stand-alone graphics, but not to be, was a one time shot last year around now.

I wanted to get more RAM, but I want to be able to upgrade it later, can I install two different RAM cards?

I currently have 4GB in my Macbook Pro. I'm realizing that this isn't sufficient. I like to edit photos and have Photoshop, Lightroom, and a web browser open at the same time. I'm pretty sure that maybe 10GB of RAM will do (I'd buy one 8GB card and keep one of the 2GB cards already installed), so in case I would need to upgrade again I could buy another 8GB card. Is it possible to have two different sizes of RAM in the two bays?
15-inch Macbook Pro (Early 2011) 2GHz Intel Core i7 4GB 133MHz DDR3

Yes, you can have two different RAM sizes in the slots. Apple doesn't recommend that, but it works. If anything make sure the RAM is the same brand. You'll need the standard 1333MHz DDR3 memory. See HERE for info on installing the memory yourself.
