Mac Pro :: Installed 4x2GB Memory Modules. Now, Have "Memory Slot Utility" Pop-up?
Mar 20, 2012
I installed 4x2GB memory modules. Now, I have a "Memory Slot Utility" pop-up(The memory modules are installed in the recommended slots) that pops up every time I start my computer. How do I get rid of this notice permanently?
I get the message: the memory modules are installed in the recommended slots. Every time I restart my 2010 Mac Pro. I upgraded my memory with 3 x 2GB OWC memories. They are properly detected, and the system is working fine.
I have a Black MacBook (Early 2008). I think that I still have the factory standard RAM sticks (I bought the Mac used from a friend). I noticed today that I am running on only one gig of RAM even though I have two gigs of memory.
3yr old black MacBook has bad memory slot. Will not boot with chip installed. Tried swapping chips and slot 1 or 2 and its the slot. So at least computer works. What are the odds 2nd slot will fail? Is that rare? Is it just a bad solder connection on main board for memory terminal? Or some tiny hidden board trace or other hard to find component?
I just bought a early 2009 MAC Pro and it came with 3GB of RAM, I ordered 3 2GB sticks of memory to replace the 3 1GB sticks that I had in there from Kingston. I turned off the unit, I popped the little levers and pulled the memory out of slot 1, 2, 3 and then replaced the memory with the new Kingston in slot 1, 2, 3
One of the sticks in is not working at all and I get the RED LED light no matter what slot I move that chip to. So I am running on 2 of the new Kingston memory chips.
Can I mix the memory and add the 1GB into slot 3 and 4 with slot 1 and 2 full of 2GB chips?
Also how to I run the memory utility again? I went to /system/Library/CoreServices/ and then I see the program Memory Slot Utility.app
How do I run this? I'm used to no spaces and I type ./then program name
While 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?
I 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?
I'm in the process of upgrading the memory on my 1st gen Mac Pro. (2 x 3.0 Ghz Xeon). Apple publishes a memory max of 16GB., but I have seen references to these machines running more. My question is, has anyone successfully run larger configurations of memory, and will these systems recognize 4GB modules?
So I read online that my PowerBook G4 that I've had since about 2004 may have the defective memory slot that caused Apple to introduce the "PowerBook G4 (15-inch 1.67/1.5GHz) Memory Slot Repair Extension Program" in 2008. However, my serial number isn't within the program's parameters, and as I understand it, the program ended in 2008. It says it applies to serial numbers W8503xxxxxx through W8518xxxxxx; mine begins with W84.
Basically, I have a couple of questions before I a) shell out money for diagnostics and possible repairs or b) buy a new laptop: Is this a memory slot problem? My 15" PowerBook G4 (Model A1045; 1 GHz; 256 MB; 60G; Combo; BT) had been getting the beach ball for awhile, and was very slow operating and online. My sound card had been on the fritz. The internal speakers would sometimes not work, but the headphone jack would still work. So yesterday, the mouse froze while in Firefox, and after waiting awhile, I forced it to shut down. When it booted up again, I got a blank screen and three short beeps, followed by the LED light blinking periodically. All these symptoms seem to point to what Apple said was the memory slot problem [URL]
If this is a memory slot problem, what might the repairs involve and are there price estimates available? Is it better to just get another laptop? (I'm thankful I've had it for this long without any major problems, it's had a good life). If I do get another laptop, am I able to retrieve my information from my old laptop and transfer it to the new one? Is this an expensive procedure? Or is this laptop entirely kaput and my files forever trapped on there? What the recommendations out there (if I buy a new one instead doing repairs to the G4) for a laptop that will be used as my only computer (i.e., what's a good workhorse Mac)?
For MacBooks with SSD drives and a SD card slot; is it practical to insert an "empty" SD card there and use it as spare flash memory to store files etc? Any downsides to doing this? Will the OS detect it like its a spare drive?
My Mac Pro doesn't boot when I have 16Gb of RAM memory installed. I want to know if is possible to deactivate slots memory in Mac OS X (Lion 10.7.4) because I will use only two slots with two 4Gb modules.
About 6 months ago my Core Duo MBP shut off and then rebooted with loud post beeps. Everything is fine since except that it can only run with 1 stick of RAM in the lower slot, with both or just the upper filled it doesn't boot and the optical drive sounds like it cant start. My 1 year warranty is out and missed the 2 year upgrade. Also does anyone know if this model can run 1x 2GB of memory? I used to have 1.5GB (came with 1x 512MB and added 1GB) and now been running with just 1 gig and missing the performance albeit a positive is Snow Leopard is a lot more snappy on 1 gig than Leopard .
07 Black Mac. 1 of the memory slots is flaky and computer will not boot unless memory is removed. Found local tech who said he could fix it for $100 or so. Does it involve changing actual memory slot? Or cleaning it?
I have a Powerbook G4 that I wanted to upgrade to 1.5G from 512MB. So I added Corsair 1GB DDR RAM to the notebook and it seems to have issues recognizing both at the the same time. When I put both of them in together, it never seems to recognize the bottom slot. Putting in the 512MB in the bottom w/o the 1GB the Powerbook boots up fine. Putting in the 1GB by itself and it gives beeping noises on bootup, but it'll boot up if I put it on the top slot.
My questions is what size of max memory and hdd could be installed in a A1181 white Macbook with 2.16Ghz (4MB L2 cache CPU) and GMA950 VGA? It is a 2007 model. Currently I have 2x1GB DDR2 667Mhz and 160GB Samsung SATA hdd.
I have a iMac DV G3/500 (Special Edition) from summer 2000. Anyway, I am using Mac OS 10.2.8. Recently, my start up disk's memory has gone done from 1.2 GB available free space to 668MB (currently). I haven't saved anything on this disk so I can not understand why this memory has dissappeared. I have also had icons on the start up menu disappear. Could someone please tell me how I can restore the missing memory?
I've had my iMac for just under a week now, and I wanted to play some games, so I did a Time Machine backup, and ran BootCamp. Vista install disk wouldnt work, so I used my copy of the Windows 7 RC1 32bit. That worked fine, its installed and working just fine, but when I went to check what it would show under "System" in the control panel, it shows my memory as 4.00GB and says 2.73GB useable. Is this normal? I know that 32 bit cuts off memory at around 3.23GB, and I was under the impression with Windows 7 and Vista SP1 the limitation was supposed to be moved to 4GB. Is this something I should be worried about? Also, I get some really bad lag spikes on Windows.
I have installed 4GB of extra ram to my MBP 13" (late 2010) to increase the performance of virtual machines. Though the VirtualBox doesn't recognize the 8GB of ram when i try to create a new machine for Windows XP 32-bit or Windows 7 64-bit. I haven't tried it with other operating systems. I have also reinsalled the VirtualBox but it didn't work.
