Crucial Memory for Nehalem Mac Pros?

Taking delivery of new Mac Pro tomorrow (dual 2.66MHz i7s) and need to add more memory. I've always had good luck with memory from Crucial. Anyone upgrade their memory for these machines yet? If so, from where? My new machine is coming with 6GB, but does it come in 1GB or 2GB sticks? ie. will I need to throw away the stock RAM? On second thought maybe it's better to do that anyway so that all the memory matches...
Any thoughts?

Take a look at this review: http://barefeats.com/nehal04.html
There is an open debate whether 3 sticks of RAM are better than 4 in these new machines. Something about groups of 3 allow for triple speed access, and groups of 4 reduce it to double speed access. I am sure I butchered that explanation. Check out the link from Barefeats. They explain it better.

UPGRADING AND MIXING MEMORY ON MY MAC PRO QUAD CORE DUAL 2.8 (Xeon)?

Hello,
I have a Mac Pro Quad Core Dual 2.8GHz (Xeons) with 4GB of memory (2 x 1GB Apple modules + 2 x 1GB other brand - Shown as "Manufacturer 0x855D") and now I want to fill the other 4 memory slots by adding an additional 16GB (4 x 4GB modules) for a total of 20GB of RAM.
My 2 questions are:
1.- In which order/pattern should I install these new 4 X 4GB modules along with my original Apple 2 x 1GB modules and the "Manufacturer 0x855D" 2 x 1GB modules the best way (for better performance)? - I have heard stories that if I do it improperly, I could slow down my Mac Pro...
This is how I have them configured right now:
Raiser A / DIMM 1 = 1GB (Manufaturer "0x830B") - I assume this is the Apple memory, right?
Raiser A / DIMM 2 = 1GB (Manufaturer "0x830B")
Raiser A / DIMM 3 = Empty
Raiser A / DIMM 4 = Empty
Raiser B / DIMM 1 = 1GB (Manufacturer "0x855D") - How can I find which manufacturer is this?
Raiser B / DIMM 2 = 1GB (Manufacturer "0x855D")
Raiser B / DIMM 3 = Empty
Raiser B / DIMM 4 = Empty
2.- What brand would be most compatible to work with my Apple 2GB (2 x 1GB) factory memory? Kingston? Crucial? Mushkin? iRam? Corsair? OWC? (Does OWC sell their own brand? or which one do they carry?-its not specified on their web)
Thank you so much in advance for all your help!

Memory Tests- "2008" Mac Pro
Ram should be installed minimally in matched pairs and optimally in matched quads. This means the memory modules are the same size and specifications. They should also be equipped with the Apple-certified style of heat sink.
Brand really doesn't mean much as long as they work.

How do I get more memory for my Macbook Pro Spring 2010 13-inch with 2.66GHz Intel Core 2 Duo?

How do I get more memory for my Macbook Pro spring 2010 13-inch with 2.66GHz Intel Core 2 Duo. Apple says no memory currently available for that model. I have 4 GB memory and 3.99 used. Help!

Also what do you mean that actual memory is 16GB but with Apple it's 8?
When I go to the "About this Mac" it says Memory 4G 1067 MHz DDR3, then when I go to System Report it says
Memory Slot
Bank 0/ DIMM0 2G DDR3 1067 MHZ OK
Bank 1/ DIMM0 2G DDR3 1067 MHZ OK
Sorry I'm clueless. Just don't want to buy something that messes up my machine more than it already is.
The Crucial site appears to have recommended the correct spec 4gB RAM stick for your model. Please note that you will need to remove the existing sticks of RAM to install new, so you will need 2x4gB to get to 8gB.
When your model of computer was designed/built, it was tested with readily available 2x4gB (8gB). After release RAM retailers have tested it with higher amounts, and Apple didn't update their quoted specs.

Where can i buy original memory for my macbook pro 13inc mid 2012 and how much is this ?

"Memory sold by the Apple Online Store is guaranteed to be compatible with your Macintosh."
http://store.apple.com/us/mac/mac-accessories/memory
Other than Apple there are only two vendors with which I have personal experience and can recommend: Crucial and OWC. People have reported problems with many other brands, yet Crucial and OWC's prices are as good as any you are likely to find.
Go to Crucial and download the little app that examines your system and recommends RAM upgrade options.
Their prices are good but don't have to buy memory from them - determine what you need and buy it from Crucial or OWC / MacSales. You'd be paying Apple a lot more than either one of them, and you don't have to.

Nehalem Mac Pro - long time to boot up?

Question... unlike the 2008 and earlier models, why does the grey apple take a little longer to get to on the nehalem mac pro? If you put the 2008 and 2009 side by side, you will see that the time the grey screen shows the apple in the middle is really much faster on the 2008 compared to the 2009 - why is this?
I thought it was a problem with my 2009 mac pro.. it seems this problem is on all of the 2009 series.. Has anyone noticed that the apple logo takes a little longer to get to on a Nehalem than on the 2008?

Btw.. this is on all the models of 2009's.. and also most likely 2010 since they use the same logic board and processor tray for the most part..(details 4th coming..)..
But, does anyone have a solution to this?? My start up drive is already selected, but yet it still takes a bit longer to boot up.. would changing the memory to non-ecc solve this problem? I heard xeon takes both non and ecc. I really don't need ecc for what i use my mac pro for..
Is there a way to disable the tests?

Power consumption for latest mac pros?

I read on Apple.com somewhere that the 2008 Mac pro's maximum power consumption is 260+ Watts for a Quad-core. How different is it for the new Mac pros?

I guess English is a lost language now.
For the Mac Pro it is really really simple and based on 7 yrs of PowerMac G5s and then Mac Pro owners: 1500VA - you can get by with slightly smaller 1300VA and some people, because of better build, used SMART UPS 1000VA.
And as I said in another thread, the Mac Pro 'suffers' from inrush current that can knock out smaller UPS, and people that have tried to use 500-900VA units got into a lot of trouble and had to upgrade.
No one can know the total system watts used other than use a KILLAWATT on the power cord.
Look at the case, can an iMac dispel as much heat as easily? no. It is designed for lower power and much fewer components.
Core i7 has HyperTransport and Turbo boost for one thing. Apple had a huge coding problem with audio (incl iTunes and others), flash and Nehalem based systems. High cpu temperature and lost processor cycles and performance.
The 2010 Mac Pro can do more for the same, and DDR3 lowered heat and watts noticeably.
There are sites where you can plug in various components and get an idea of how large a PSU would be needed. Try one of those, too. PSU efficiency, and there is "overhead" needed for the motherboard chips and to run PCI Express for graphics, Firewire, etc. It all adds up.
Apple's example is low-end system configuration, the chart says CPU MAX, not SYSTEM (but then, most everything on hardware requirements lately needs a grain of salt).
Quad-core 2.66GHz configuration:
One 2.66GHz Quad-Core Intel Xeon "Nehalem" 3500 series processor,
3GB memory (three 1GB 1066MHz DDR3 ECC DIMMs),
640 GB Serial ATA 3 Gb/s 7200-rpm hard drive,
18x double-layer SuperDrive,
NVIDIA GeForce GT 120 with 512MB of GDDR3 memory
APC we know, whether PowerMac 2.0DP from 2003 or Quad G5, or Mac Pro, that 1500VA is strongly recommended.

Wait for new Mac Pro's or buy a 27" iMac?

Hi, I currently own an early 2009 2.66 ghz Quad Core Mac Pro with 8 gigs of memory. My Mac Pro has 4 internal Hard drives filled up with data (over 4 tb of storage space).
I plan to upgrade to either the new Mac Pro's (ariving in late July or early august) or the new 27" iMac. I'm aware that if I went with the Mac Pro then I will need to buy a 27" LED Cinema display.
How do the new 27" iMac's with SSD drives in terms of performance compare to my older Mac Pro? Storage space is important to me.
If I customized a 27" imac then I would get it with 16 gb of memory, a 256gb SSD and a 2TB Drive. unfortunately it's still not much space for me. One option is to buy a Drobo FS NAS and add additional storage to my imac that way. The other is to wait for the new Mac Pro's.
The other is the price. I don't want to spend more than $4000 for a new computer. If I customized a current Mac Pro with 512gb SSD and a 2tb drive, (I will add more drives in the future) a 27" LED Apple Cinema Display, 16 gb of memory then I will be paying over $6000.
That's way higher than I'd like to spend. Will the new Mac Pro's have much improved for cheaper?
What do you think that I should do?

Why not see what Barefeats and Macperformanceguide have already done in terms of performance and buying advice?
With iMac, you don't compete with say 6-core 3.33GHz or have upgrad options and may be limited in other ways. And of course you don't want to pay for Apple price and slow SSD. Besides which most Mac Pro owners use an SSD for system, and don't want 500GB SSD (which is what Apple's would be).
just buy a good SSD now from OWC now. Buy the minimal configuration from Apple, a WD Black 2TB is less than $149.
As for outgrowning a two year old Mac Pro... see if you can upgrade the processor.
Do you think you will be ready for having to use Lion and that your software will be too?
The 2010 2.8GHz $2119 + 3 x 8GB OWC, SSD, W3670 3.2GHz 6-core $600 is not even $3995. As for 27" I leave that to others and whether 3rd party. But, you're saying you can't use the monitor you have now?

SSDs for 2008 Mac Pro

I'm thinking about buying an SSD for my Mac Pro (see specs in my signature), any recommendations? I've been a big fan of products from OWC in the past, so I'm considering their Mercury line. On the other hand, Crucial drives are a bit cheaper (especially on Amazon). Question: would there be any point in my getting an M4 from Crucial rather than a V4? My understanding is that the primary difference is the 6gb/s vs. 3gb/s transfer rates, but that my Mac Pro can only handle 3gb/s anyway.
I'm still on Snow Leopard for now, but I'm looking into whether or not Mountain Lion will be a worthwhile upgrade for me--still not sure about compatibility of certain key apps in my workflow.

The main improvement in performance in a Mac Pro is establishing a boot drive with only System, Library, Applications and the hidden Unix files including paging/swap.
The bulk of the performance increase is not from the speed of the Boot Drive, but from what it is NOT doing -- it is not moving the Data Drive heads away from your data files to go "snacking" for system files or Paging in the middle of your production work. At a cost of tens of milliseconds for every access plus that much time again to get back to the Data areas.
ANY separate drive will produce the majority of the improvement.
A faster drive will produce a slight incremental improvement. A low-latency SSD will produce another slight incremental improvement. These incremental improvements will be most perceptible in a very slightly faster boot-up time and very slightly faster Application launch times.
You are concentrating on the absolute LEAST important issues, that will have the smallest, possibly not even perceptible performance impacts.
My Advice: Get a Boot Drive that is cheap and live happily ever after.

New HD for a Mac Pro

This is my first time buying an internal hard drive so i want to make sure I buy a good one. The one I'm looking at right now is the Seagate Barracuda XT ST32000641AS 2TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive. Will this work with an 8 Core Intel Xeon Mac Pro G5 (early 2009 I believe)? Also I'll probably get 2 if I buy this HD, if that makes any difference.

Hi Manged,
The early 2009 Mac Pros have Intel Xeon "Nehalem" processors, and, as Clio 1 has already advised you, G5s are not Mac Pros.
Mac Pros were first released in 2006, and have always had Intel processors, whereas their predecessors were Power Macs which had PowerPC G5 processors.
There were no 8-Core Power Macs, and so it would seem that you have an early 2009 8-Core Nehalem Mac Pro.
You can confirm what model you have by clicking on About This Mac/More Info, and then looking at Model Identifier under the Hardware Overview heading. If MacPro4,1 is listed, then you have an early 2009 Nehalem Mac Pro.
Very few Mac Pro users would recommend Seagate drives. Western Digital and Hitachi are regarded as being better and more reliable.
The Western Digital Caviar Black is an excellent choice, and is probably the HDD which is most often recommended on these Mac pro pages
http://macperformanceguide.com/Storage-Drive-WesternDigital-CaviarBlack-2TB.html
The above link is a bit out of date, and this is the manufacturer's current website page for its Caviar Black Range:
http://www.wdc.com/en/products/products.aspx?id=100
You have stated that you want to make sure that you buy a good drive. So my advice, is to disregard the Seagate Barracuda, and buy Western Digital instead.
Buy the WD Caviar Black, unless you intend to set up a RAID configuration with these drives, in which case the more expensive RE4 Enterprise is a better option.
If you do intend to set up a RAID, one very important consideration is that all the drives in the configuration should be identical.
Regards,
Bill

What is a recommended internal hard drive for a Mac Pro 1,1 (2006)?

What is a recommended internal hard drive for a Mac Pro 1,1 (2006) model? I would like to
add more hard drive space by utilizing the three available slots. However, from my understanding,
Apple does not produce hard drives for my older computer so I'll need to turn to a third party.

You are very much over-due for some new larger more efficient drives.
the most common best approach goes something like this....
SSD 120GB for system
WD Black 1-2TB for data (and put all your data and media files, all your home account sub-folders)
Backup. I use WD Green but use what you want. I have a small boot volume, TimeMachine, and 3rd that is a clone image of the boot drive volume.
Very fond of WD 10K VelociRaptor drives. Not much louder now than the WD Black 2TB, $100-200 for 250GB to 1TB.
You can use any size SATA 3.5" drive, most now are 1TB and up to 4TB.
You should have always bought Amazon or Newegg or outside of Apple, Apple can often charge 3x what those places charge.
Probably want to add or replace FBDIMMs you have, these are excellent and price in the last year has fallen.
2x2GB FBDIMM DDR2 667MHz @ $29
http://www.amazon.com/BUFFERED-PC2-5300-FB-DIMM-APPLE-Memory/dp/B002ORUUAC/
WD Black 1TB $93
http://www.amazon.com/Western-Digital-Caviar-Internal-Desktop/dp/B0036Q7MV0/
WD Green 3TB $149 - backup
http://www.amazon.com/Western-Digital-Caviar-Green-Desktop/dp/B004RORMF6/
WD VR 10K 250GB $103 200MB/sec boot drive :
http://www.amazon.com/gp/product/B007V5A1BK/
Those last and last and make a nice boot drive.
SSD: Samsung 840 128GB
http://www.amazon.com/Samsung-Series-120GB-internal-MZ-7TD120BW/dp/B009NHAF06/
Over-due to upgrade and replace the graphic card most likely it sounds like also:
ATI Radeon 5770

Your OEM 7300GT isn't helping now and with Lion or the X1900 dust magnet and out of date too. If you have a functional 8800GT still working you are lucky and no need.

How do I use Airport Extreme to act as a wireless receiver for a Mac Pro?

Hello -
I'm trying to use an Airport Extreme (1st Generation) as a wireless receiver for a Mac Pro but I can't figure out how. My main modem / wireless router (non-Apple) is upstairs. My Mac Pro is down stairs. I'm looking to get internet connection for that Mac Pro downstairs. Is it possible to use the Airport Extreme to connect the Mac Pro to the wireless internet provided by my wireless router?
Thanks for the help.
Nathan

Is it possible to use the Airport Extreme to connect the Mac Pro to the wireless internet provided by my wireless router?
Unfortunately, Apple designed their routers to work with other Apple routers. It would be extremely unilikely that the AirPort Exteme could be configured to work with a router from another manufacturer.
The AirPort Extreme would need to be configured to "Extend a wireless network", but an error message is almost surely to occur when you try this.
There are other alternatives, but they would involve more hardware. Post back if you are interested.

Can an iMac be used as a monitor for a Mac Pro?

Hi all,
I'm getting nowhere looking in the search, so I'm hoping someone can clear something up for me:
is it possible to use an iMac as a display for a Mac Pro?
I am beginning to think I'd better get a Mac Pro, but I already have an iMac, for which I've been researching getting external storage so I can do Final Cut Studio editing and back up of it all... as someone suggested, might be better in the long run to just get it all in the Mac Pro, and have the option and simplicity to upgrade as and when... but then there's the need for a display for the Mac Pro, which does whack the price up... but if I could use this iMac, what a beautiful monitor...
I thought someone said that Final Cut would not allow another computer to be attached though... is that the case, anyone know?
Thanks for any knowledge and help, much appreciated... I'm learning to not rush into anything, as you learn more the whole picture seems to change!
Cheers, Syd

The current 27-inch iMac can. Other iMac models can't outside of a VNC setup or ScreenRecycler; all such solutions require a standalone monitor for setup and troubleshooting.

I have a belkin 7 adapter for additional USB slots for my Mac Pro. It was working well till just recently I am getting a message that says the usb port on the Mac Pro is shutting down due to a very high power drain. Then it shuts the usb port down.

I have a belkin 7 adapter for additional usb ports for my mac pro. It worked fine without problems till recently when the message regarding usb port drawing too much power and the computer shuts the port on the mac pro down. The strip comes with its own power supply adapter. The attachments are additional hard drives used as backups and independent data. Other than disconnecting it are there any fixes?

You're getting the message because you're exceeding the available current, probably as a result of bus-powered drives. The power sources for hubs are rather small. Try using drives with their own power supplies.

Where can I obtain the AHT on disk for my Mac Pro 4.1?

Where can I obtain a disk (iso) of the AHT for my Mac Pro 4.1 (latest OS X Yosemite) that I am busy upgrading?

If you can fiddle with file permissions without going nuts, the original gray discs or the downloads mentioned (once the .dmg is mounted) provide a roughly 60 to 100 MByte .diagnostics [invisible] directory at:
/Volumes/disc_name/System/Library/CoreServices/.diagnostics
You can see this folder (on the DVD or in the download) with the Finder by looking in CoreServices, using the Find command and specifying name .diagnostics and Visibility [invisible].
Open a second Finder window and navigate to the comparable place in the current Directory structure:
/System/Library/CoreServices
drag and drop the .diagnostics directory from the DVD or the download in one window to the current Core Services folder in the other window. Observe carefully to see that it actually does the copy, as Find-ing it in the current directory structure is quirky.
You may have to authenticate as Admin, or you may already have access --
-- otherwise you can change the permissions of the current CoreServices folder to allow you to Read & Write
-- don't forget to change permissions back if you modified them.
NOW try Restart and hold the D key.
