Jul 4, 2012I've bought new memory for my by my Mac Pro 2.8Mhz Quad Core mid 2010. It is 4x Kingston KTA-MP1066QR/8G memory. Installing went well, but it's clocked down to 800Mhz by the Mac. Why? And more important how can I fix it so I will have my 4x8GB @ 1066Mhz?

Jul 30, 2010I am planning to upgrade the standard 4gb of on my April 2010 Macbook Pro (the basic 2.4ghz model) to 6gb.
Over on Crucial memory suppliers they advise using two identical modules, i.e. 2 4gb sticks rather than 1 2gb + 1 4gb.
Can anyone chip in on whether this is good advise or just them trying to make a few more bucks?
For my needs 6gb should be perfect, I have a desktop already with that amount, although to be fair the desktop is 3 * 2gb modules.
Laptops :: Macbook Pro Ram Upgrade - Removed New Ram Modules And Refitted The Old Ones?
Jan 8, 2010I have a macbook pro of 8months old.The machine is fitted with 4gb ram, 2 x 2, but is able to be fitted with 8 gb.I bought 2 x 4gb of the same type of ram: 1067 MHz DDR3When it was fitted, the computer performed great, Autocad was flying.
Alas, after a few hours the computer went berserk and started to behave odd, refused to open a prog, refused to stop and finally refused to re-start.
When I removed the new ram modules and re-fitted the old ones, I found out that my hdd was not mountable. I did resolve the issue but lost some data in the process.
Mac Pro :: RAM Modules Must All Be Of The Same Manufacturing?
Jan 16, 2010I want to know if the wool is being pulled over my eyes by OWC. The site says that their 4GB modules for a Mac Pro Intel Xeon Quad-Core 2.66MHz can only be put into the tower if the original Apple modules are first removed. Something makes me think that this is a salesman's bluff. Anyone know for sure? Sorry if an answer to this question has already been given elsewhere.

Jul 30, 2010I know the newer Intel QPI processors have three main-memory channels, and I've seen much discussion and several complaints on these threads that Apple didn't expand their memory risers to squeeze in six DRAM sockets instead of four, so that the module count on each riser could be a multiple of 3. (And also that they should have done this for the 2009 Nehalems).
Here's my question: what kind of performance would I be losing and why if I got one of these new Westmere machines, discarded Apple's stock memory and replaced it with 4--rather than 3--OWC 4GB sticks? What I specifically don't understand is, can't the QPI fetch from any 3 of the 4 modules at once?
IMac :: Using 2 Or 3 Memory Modules?
Nov 18, 2009While browsing around I've stumbled over a few references to things like "tri-channel memory" and such. From what I understand (not that good with these things) some computer architectures / CPUs are optimized for using 3 memory modules, and some for using pairs (2 or 4).
I just read some benchmark tests of the i7 with different memory configurations, and the 12Gb was is most cases on par or better than all the others when it came to performance, even better than the 16Gb one. Is the new iMac (i7) best suited to use 3 memory modules?
Mac :: RAM For 6 Core Westmere Pro In 3x1GB Modules
Oct 10, 2010I've read many of the threads regarding RAM pricing and configurations for the 6-Core systems. I planned on ordering my Pro with 6Gb instead of the default 3GB, but my friend at Apple forgot when he placed the order. what I understand RAM module placement and type may significantly impact system performance for this platform. As I need to double the RAM, should I purchase 3x1GB modules to add or purchase 3x2GB models and sell the 3x1 that came with the system? Also, which is the best RAM retailer, OWC, Crucial, etc?

Mar 29, 2008I recently installed (4) - 4gb RAM modules and I'm worried that they may be running too hot. The image attached is from the machine just essentially sitting idle all day. Only 1gb of the 17gb are wired. When I do put the Mac to work, either through Handbrake or running Autocad through Fusion, the temp on module A1 reaches 173 degrees and the fan speed just about doubles.

Jul 25, 2008I bought a refurbished Mac Pro (8 core) from the apple store and added 4 Gb (2x2Gb) to the 2 Gb tht came installed. I am having a peculiar problem in seeing all four of the memory modules. The only setup that shows all 6 Gb of the memory is to have the modules in the following format: a) 2Gb modules on Riser A, positions 1 and 3 plus 1 Gb mods on Riser B positions 1 and 3; b) 2 Gb and 1 Gb mods on Riser A positions 1 and 3, respectively, and the same on Riser B.
When I put them in the logically (and aesthetically better) intuitive configuration of paired mods in positions 1 and 2 of each Riser, I can only see the modules that are in position 1 of each riser. Is this something expected in the new MacPros? Is there a disadvantage of keeping this configuration? I note that a memory installation video on line stated that the way memory is installed in the early 2008 Mac Pros has changed. Does this issue result from that change?
PowerPC :: G4 RAM Modules And Error Code
May 4, 2009I have an old PowerMac G4 (AGP Graphics), which has served me dutifully for a long time. However, I recently took all but 128mb of the ram out to temporarily use in other computers, and when I went to put the modules back in, basically none of them worked. Here's the deal: I have 2 256 modules, and when I put those in my computer, whether individually, together, or with other modules, I get this message on-screen and the computer does not boot: localhost:/ root# []. Similarly, I have 3 128mb sticks, but if I put more than one in the computer at a time, I get the same message. I'm thinking the computer may have some issue with more than 128mb of ram, but why all of a sudden? I don't really know anything about code or whatever the computer is trying to tell me.

Aug 18, 2008I have this 1.42GHz G4 Mac Mini that my mother uses for very basic stuff but still gets bogged down by skype videoconferencing or by having more than a couple of tabs open on the browser. I was thinking of adding some RAM to its original 512MB (DDR 3200 on 1 module).
I checked prices on Ebuyer and 1GB of DDR3200 SODIMM will set me back �26 while a DDR4200 module of the same capacity will cost �13. I was wondering if it would be OK to mix the 2 memory types and get 1.5GB, or if I should replace the original RAM completely.

IMac :: Adding Single 4GB Module To Existing Two 2GB Modules?
Apr 16, 2009I've got a refurb 21.5" iMac 3.06GHz/4GB RAM/500GB HDD arriving soon.I believe it has two 2GB modules installed in two of the four memory slots, with two other slots unused. I have a few questions before I order more RAM for my machine.
Is it advisable to have ALL the RAM modules be of identical brand and size?Can other brands of RAM be added to the two empty slots as long as they are of the same specifications? Do RAM modules need to be added in pairs or is single ok?Can the added RAM modules be of any size (1GB, 2GB, or 4GB) and still work fine with the factory installed 2GB modules?
For example, would there be any performance problem by adding a single 4GB module to the existing two 2GB modules? Or would it be better to add two 2GB modules rather than a single 4GB module?

Software :: How To: Delay Printing Change Name Change Setting Of Printers
Apr 29, 2002Q1: how can I delay printing? This was possible in OS9.
I have a thermal printer wich permits me to change the ribbon (Black, CMY, CMYK). If I have a mixed type of files to print, I'd put on hold (in the "print" window) the files that requires the unloaded ribbon while waiting for the other to print.
Of course, I can print all the CMYK, wait until it's done then print the B/W ones but I don't find it practical. Or I can also rush to the print center and hope to have the time to suspend manualy the ones that need it.
Q2: Once a printer is created, how can I change the associated ppd? This also was possible with OS9.
Q3: It is possible to change the printer name once it is created?
Software :: Change Permissions Whenever Access And Change By Another Account
Jun 6, 2009I've been changing the permissions on some of my folders and files in my normal user account so they can be accessed and changed by another account. Problem is, I have a program that saves new files into a particular folder. When it saves the new file, the permissions are the default, meaning I have to change them myself in order to make them writeable by the new account. So my first question is - is there a way to make my first user account always save files with a set of permissions that I specify?
My next question is - what should these permissions be? Both of the accounts are admin accounts. Should I therefore set group to be 'admin' and give rwx permissions to the group? Or is it possible to set owner to 'admin'? Can a file be owned by a group? Looking forward to your answers! This UNIX stuff is fun!
