Mac Pro Max resolution

Hi - I bought last week a brand new Mac Pro 2010 with 12 core processor and the ATI Radeon HD 5770 card, I have two 27 inch displays both capable of resolutions of 2,560 x 1,440. I am using a DVI to mini-port adapter for the second monitor and the DVI port for the primary monitor. The max resolution I am given on the secondary monitor is 1920 x 1080. However the primary monitor using the DVI port comes in at a much lower resolution. Any ideas on what I am doing wrong. I thought I would be able to run both monitors at 2560 x 1440 resolution. Any help would be greatly appreciated. Thanks in advance!

DVI to mini-port adapter for the second monitor
The 5770 card is perfectly capable of running 3 30" displays.
To run a display wider than 1920 wide, you will need a Dual-Link DVI converter from Mini DisplayPort. Dual-Link means the three main data lines are doubled in the adapters, connectors, and cables to support the higer data rates required. Dual-Link DVI connectors must always have the entire central grid of pins present.
Apple sells a very nice one for US$100. It uses an additional USB pigtail to pick up extra power to run the signal re-drivers. Accell makes a similar one for a few dollars less.

Upgrade Memory on 2009 4 core Mac Pro - Max? Non-ECC?

I've been doing research on what I can do to upgrade my RAM on my Mac Pro and I think I did something I wasn't supposed to do a while back.
During my last upgrade adventure, I apparently purchased and installed a 2GB stick of Non-ECC (PC3-8500 1066MHz) RAM to fill the one empty slot. The computer shipped with 3 bars of 1GB ECC memory.
Now, as I scan the web for info on what kind of memory I can get away with, everything I'm seeing says that you should not mix ECC and Non-ECC. But I've been running both for about a year now.
So my questions:
1. Should/can I use Non-ECC Memory?
2. If so, should I not be mixing?
3. What is the Max amount of memory my Mac Pro can handle? I'm seeing some info that says 4x2GB, and I'm seeing other info that says 4x4GB. Which is correct?
Thanks.

When you get a lot of memory in a computer, it is more likely so suffer an occasional memory error. This can cause serious problems that can lie hidden for months. It can take a very long time to isolate the problem and find the bad component and remove it, and the damage may have propagated throughout the files on your Hard drive.
Use System Profiler \[About this Mac > More Info] and click the "Memory" category. You will see an indication of whether each DIMM is ECC, and also a main status of "ECC ON" or "ECC OFF".
You are very lucky to own a Mac that has additional Hardware to support Error Correcting Code ECC Memory. IF ECC is active, you get enormous peace-of-mind. Any single-bit errors will be corrected, and double bit errors will stop your Mac immediately -- long before the problem can contaminate anything else.
I suggest you use only ECC memories, and make certain ECC is always ON.
Apple does not currently sell 4GB DIMMs, but others do, as noted above. Most sellers of 4GB DIMMs also warn you that you cannot mix 4GB DIMMs with 1GB or 2GB DIMMs.

10.5.2 and Mac Pro monitor resolution issue

I installed 10.5.2 this morning from Software Update and it has now defaulted to a resolution that my LCD monitor cannot display. I can't even boot into Open Firmware, to the Mac Pro DVD, or bring up the drive selection screen (holding down Option when booting) as my LCD continues to say that it cannot support the resolution of the Mac Pro.
I had the settings set to the native resolution (1280x1024) before installing the 10.5.2 update and had all updates before the 10.5.2 update installed prior to installing it. I have reset the PRAM many times, reset the SMU, and tried connecting the LCD via both VGA (with the converter) and DVI. I plugged in an old CRT monitor and was then able to get into System Preferences but even after setting the LCD to the correct resolution and refresh rate it continues to say it is being sent an unsupported resolution. My LCD is a Samsung monitor but I don't recall the exact model number right now.
With the CRT monitor I was able to start downloaded the latest graphics update via Software Update but had to leave for work before I could install it and see if that fixed the problem.
I have seen a number of Mac Book Pro users with an external display problem after updating but was wondering if any Mac Pro users were having this problem or if anyone knows how to fix it. Thank you for your assistance.

Update: My monitor is a Samsung 913T and is less than 2 years old. I installed the driver update via Software Update but there was no change in behavior. Any CRT monitor I hook up works fine but I don't have another LCD to test. I tried reinstalling the 10.5.2 update but there was no change with that either.
I am now using Time Machine to roll back my Mac from right before I applied the 10.5.2 update. I doubt this will fix the problem as it seems to be deeper than that but I figured it was worth a try. I'll also be calling AppleCare support on Monday (hopefully they aren't closed for the federal holiday). I am still seeking any help or suggestions on this front. I don't have the money for a new monitor at this time and would really like to get my current LCD working as it was before with 10.5.1.

Mac Mini Max Resolution?;CRT

I just bought a Mac mini and am looking to buy a CRT. What are the max resolutions the mini can support? (VGA analog, not DVI digital)
And, if the mini's supported refresh rate for a given size is say 100Hz and the CRT is only 70 Hz, will it still work?

For DVI it'll go up to 1920x1200. For VGA, probably higher, though I doubt it really matters at that point. For the refresh rate, you can lower it on the Mac, so it shouldn't be a problem.

Mac Pro max GPU power consumption limit?

Hey guys,
What's the max power consumption limit for the Mac Pro's 2 GPU Mini PCl-e power slots? I have to know because I have to decide which GPU I plan on buying. I'd be thankful if someone helped me with this.
Oh and it's a Mid-2012 12-core Mac Pro.
Cheers!

you might want to look at www.barefeats.com and then probably limit to Mac edition cards. Budget and what you hope to achieve. And whether you want it mostly for games in Windows and w/o boot screen or even willing to add a 2nd PSU just for power and 2 x 8-pin plus 2 x 6-pin power.
EVGA Mac Edition GTX 680 is two 6-pin and $580 area.
AMD has Mac Edition 7950
You will actually find more about unsupported cards and their use on MacRumors. And you do need 10.8.3+ for most anything beyond Apple's ATI 5x70.
I don't think looking at power usage is where I would have started my search.

Camileo Pro Max Resolution D1 or VGA?

Hello,
I am confused with the resolution specifications of Camileo Pro.
All the product specs, description and ads say VGA (640 x 480) as max resolution.
The manual however claims a max resolution of D1 (720 x 480) .
What is correct?
Any experience? Have you tried out?

As far as I know you can record the movies with a MPEG-4 640 x 480 resolution and 30 Frames per second.
Please check the manual again maybe the mentioned resolution is not related to the movie recording

Mac Mini max resolutions for 2 screens?

Hi all. I have the latest Mac Mini and I'm currently running a Samsung 24" at 1920x1080 from the Mini Displayport socket via a DVI adaptor, and also a second display at 1280x1024 from the HDMI socket via DVI adaptor.
I'm looking to upgrade the Samsung to a screen that's 1920x1200 resolution - I'm assuming the Mini can handle this slight increase but I can't find specs anywhere for this. Would it even run a 2560x1600 screen alongside the 1280x1024 one?
Many thanks in advance.

The > Mac mini (Late 2012) - Technical Specifications doesn't clearly state what the maximum resolution for each output is.
Funny part is, that the Spec's for the previous Mac Mini 2010 and 2011 models does.
One would think that they are the same? Unfortunately that would be pure speculation and contrary to the ASC Terms of Use.
On that note: Your best bet might be to > Contact Apple Support and get some clarification.

The resolution on my Mac Pro is suddenly wrong. I can not find a size that works. Help?

Mac Pro: the resolution has changed to be slightly larger than my screen. I can not find a setting to correct this. Any suggestions? Thanks.

Have you checked that zoom is turned off? Open System Preferences > Universal Access, and turn off Zoom. You can also try to hold the Control key and scroll down, so zoom will be turned off.
If it doesn't work, open System Preferences > Displays, and choose the biggest resolution

Original Mac Pro Installation Discs won't allow me to reinstall!

Hi All
I just got hold of a second hand Mac Pro. All seems good until I notice that there's no iPhoto on it, and thats a bit of a must as its for a Photography Studio!
Went to install from the "Mac Pro Applications Install DVD" and get an error:
Alert: You cannot install this software on your computer
So I thought I'd just reinstall the whole system (don't really have time to spend hours troubleshooting) but I get the same problem with the "Mac Pro Max OS X Install DVD".
So any ideas? The discs came in the box with the Mac and everything else seems ok.... has someone fobbed me off with the wrong discs?
Cheers
Mark

The disks it came with aren't for that model, aren't OEM
And it would have been better to "troubleshoot" the iPhoto, though I would say it isn't a Pro app or one that a Studio would rely on and use.
A box set of retail OS X + iLife/iWork
2006 had dual / dual-core, and 2009 had a single processor quad-core.
5GB though won't take you very far.
If the Install DVD says "10.4.x" what do you see inside or in System Profile about hardware model, graphic card, processors, type of RAM?

Is the new Core i7 MacBook Pro as fast as my quad core Mac Pro?

Hello,
I'm wondering if someone could advise me about the relative power of my current Mac Pro (2 x 3 GHz Dual-Core Intel Xeon 8GB RAM), and the new 17" MacBook Pro (2.66GHz Core i7 8GB RAM). Is there a website that details such comparisons?
The reason being that I'm thinking of exchanging my Mac Pro for a MacBook Pro, so that I would be able to have a more mobile system. If the processing speed, on tasks such as video encoding, was similar between these machines, then I am tempted.
Other than processing speed, I'm wondering if there would be any disadvantages to going ahead with this swap. One thing that comes to mind is that I would need to unplug a number of cables when taking the MacBook Pro on the road, but as I wouldn't be doing so a lot I don't see this as a particular issue. In terms of storage, I would be getting external enclosures to house the SATA drives currently in my Mac Pro and connecting them to the Macbook Pro through FireWire 800, which presumably means slower transfers between the drives, but again, this isn't a particular concern as transfer speeds would still be pretty fast.
My Mac Pro is connected to an Apple Cinema Display so obviously I would keep hold of that as a display for the MacBook Pro, and use my Apple keyboard/mouse as well.
Are there any other disadvantages that I haven't considered?
Thanks
Nick

OK. Here's some test results. The most intense process I use on my Macs is using Handbrake to encode either DVDs or mkv files to mp4 files which generally pushes all cores to the max. I am using the latest 64bit version of Handbrake on both Macs.
So I took a sample mkv file of 65 seconds length and ran it using the same settings on both the Mac Pro (2 x 3 GHz Dual-Core Intel Xeon 8GB RAM) and the Macbook Pro (2.66 GHz Intel Core i7 4GB RAM), straight after starting up both Macs so that there was plenty of RAM to spare on both. I ran the test two times on each Mac and got similar results both times, with the best results on each machine being as follows:
Mac Pro: max RAM used: 380MB, Time for encode: 102 seconds
Macbook Pro: max RAM used: 495MB, Time for encode: 84 seconds
This was for a 2-pass encoding with Turbo first pass to 2200kbps MP4 file from 720p mkv file.
So the Macbook Pro is coming in considerably quicker for this particular task. I'm not sure why the Mac Pro used less RAM, and whether this is the main factor in the time difference. Like I said, there was plenty of unused RAM on both Macs when I ran the test. I am no expert on the inner workings of Macs!
Needless to say though, I am happy with the results and very happy with the new Macbook Pro.

I have a new macbook pro and an LG w2361v monitor. The max resolution the mac is allowing me to set is 1400x1050, why can't I get to the max resolution the monitor can accept (1900x1080)

I have a new macbook pro and an LG w2361v monitor. The max resolution the mac is allowing me to set is 1400x1050, why can't I get to the max resolution the monitor can accept (1900x1080)? I know that the monitor is able to accept this resolution but It can't seem to find it. Is it something to do with the new thunderbolt port? or the fact that I'm utilizing the VGA adaptor? I could go HDMI if that works better.

Use DVI or HDMI.
VGA runs out of steam after a while.

4x NVIDIA GeForce 7300 GT cards in a Mac Pro run below max supported speed

Hi,
We have 4 "identical" NVIDIA GeForce 7300 GT 256MB cards in one Mac Pro (to support 8 DVI monitors for a Network Operations Center). One card came with the system, the other cards were purchased from Apple at the same time. This was a refurbished computer, so we didn't have the build-to-order option. I put identical in quotes because they seem to have different ROM revisions.
The system mainly shows graphs on webpages and HP OpenView (via X11), so no heavy-duty gaming or refreshes.
We have been running with 6 monitors for the past 4 months with the following monitors:
- 1x 42" LCD with 1280x768, 32 bit color, DVI
- 5x 22" LCD with 1680x1050, 60Hz, 32 bit color, DVI
When I restart the system, at least one of the 22" monitors takes 5 or 10 minutes of flashing on then off (mostly off) before it finally syncs up and shows a constant image. The 42" LCD won't go to its native resolution (can't recall what that is right now), so have to go down to a less optional 1280x768. In the next day or so, I'll be connecting one more identical 22" LCD and then soon after another 42" monitor, but am wondering if they will work. Yesterday, I saw a post about firmware update for this video card (http://www.apple.com/support/downloads/geforce7300gtfirmwareupdate.html). I also noticed that two of the cards have ROM Revision 3008 and two have 3011 ROM Revision of the cards (in System Profiler). I'm not sure yet if this firmware update increases the ROM Revision.
Running the Expansion Slot Utility (/System/Library/CoreServices/) shows that my PCI Express profile is set to Two x8 Lane + Two x4 Lane slots. All slots say that they are running below maximum speed.
The store.apple.com site still shows this configuration as a valid build-to-order, but I wonder if they do something different or extra.
Does anyone else have experience with 4 of these video cards with this many monitors?
Any experience with the Firmware Upgrade that I should know about?
Thank for any insight!

I notice that the flasher is connected to a card with ROM revision 3011, the later one.
I noticed this too.
now, to the slot profiles.
you say;
"The first one that I enter is the one to the right (looking from the back of the system)."
so you mean that the mac is laying on its side and your in the back, and what you call 'slot 1' is to the right? is that correct?
No, the system is upright, but the cards are horizontally seated. Pardon my ascii art, but here's the layout if I look from the back of the Mac Pro:
| DVI DVI ---->> slot 4
| DVI DVI ---->> slot 3
| DVI DVI ---->> slot 2
| DVI DVI ---->> slot 1
So, there are two DVI ports on each card (which is in a slot). I'm not sure which lane is which.
Either the left (as pictured) is lane 1, or the right (as pictured) is lane 2.
i ask because i'm wondering if your reproducing the way the expansion slot utility is graphically portraying it. I'm pretty sure the utility is showing the slots as if the mac is upright and the person is looking into the side of it with the access panel off.
Okay, sounds logical!
if you say that you have two x4 lanes and two x8 lanes, then i'm deducing that your flasher is on an x4 lane, and as it is, one of your x8 lanes has only one lonely monitor on it.
Probably correct.
In my utility window, it is the fourth configuration, so you would have at the moment;
slot4__x4__22" and 22"
slot3__x4__42" and 22" flasher
slot2__x8__22" and empty
slot1__x8__22" and 22"
I think that you have 2 and 3 reversed.
i would suggest trying the third configuration thusly;
slot4__x8__22" and 22"
slot3__x1__22" and empty
slot2__x8__42" and 22" flasher
slot1__x8__22" and 22"
in other words, check off the third configuration in the utility, then
exchange the connections on the second and third cards, leaving the first and fourth cards be.
Okay, will do.
as far as running below max speed, i figure as long as your workload doesn't suffer, then its fine.
Oh, and another question, does it always, always flash when you boot-up?
Do you guys shut down the system every night?
We rarely reboot it, and I'm not the only one that would see it reboot. This system is in a 24x7 Network Operations Center. I just know that rebooting takes a while for the monitor to come up all of the way.
Thanks for all of your help and guidance so far!

Windows 8.1 Pro on Mac pro resolution problem

I have created a partition for windows 8.1 pro on my 13' retina display mac pro via boot camp, everything is fine except the resolution, when i open the browser, i could see pixels, the words aren't very sharp, but this isn't my biggest problem, when i open the Solidworks software i'm working on, the icons are too small, or the texts are too big for their boxes. what is happening here? anyone knows what is all about, or how to fix this? changing the resolution of the display didn't solve the problem.

This is how the words look like in the browser page, you could see pixels. The maximum resolution for this machine is 2560*1600

Appreciate your support and if possible , how to do this?

If you want to work with Mac OS X, you need one computer per simultaneous user.
What you are describing, " Multiple simultaneous logins to a single computer" is not avialable on a regular Mac of any description, unless you decide to use Unix tools instead of Mac OS X.
Server will happily store files for many, many users and provide them to multiple (up to hundreds) of computers at "near hard Drive" speeds over Gigabit Ethernet. It can make the File Sharing part easy.

When I power up my Mac-Pro I only get a flashing file folder with a ? inside the folder. I suspect my hard drive is maxed to capacity can anyone help me as to what I should do?

Whatever the problem is you no longer have a bootable system. You need to try reinstalling OS X.
Reinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
