Undestanding the Compatibility Test on Memory Modules

Hello,
I don't understand well the official Compatibility Test on Memory Modules.
For example, let's take my memory : Infineon HYB25D256800CE-5C 512 MB DDR400.
How should i read the sheet?
- It works when 3 modules are installed at the same time in Slot 1,2 and 3 and :
- It works when 2 modules are installed at the same time in Slot 1 and 3 ?
OR :
- It works whenever a module is installed in Slot 1 OR Slot 2 OR Slot 3?
I'm a bit confused....
Any help would be appreciated,
Thanks,
Nico'

Welcome to Apple Support Communities
The Mid 2011 Mac mini supports 8 GB of memory officially, but you can install up to 16 GB of RAM, so you can use 2, 4 and 8 GB modules. You can buy more RAM from OWC or Crucial.
If you are looking for memory at a local shop, make sure you buy 1333 MHz DDR3 memory. See > http://support.apple.com/kb/HT4432?viewlocale=en_US&locale=en_US

How to test 'Matching' memory modules - iMac G5 (ALS)

Hi there,
Does anyone know of a way of checking whether memory modules are working at 128-bit rather than 64-bit?
For reasons of cost and availability, I have installed two 1GB DIMMs from different manufacturers in my iMac G5 (ALS).
As per the Apple article:
http://docs.info.apple.com/article.html?artnum=300082
The specifications seem to be matching ie, they are both:
184-pin
Non-EEC
Unbuffered
PC3200U-30330
CL3
16 devices
So, in theory, they should be working at 128-bit in dual-inline mode. System Profiler just says they are both 1GB PC3200U-30330 modules and that they are both OK.
So is there a way of telling for definite...out of interest...my computer seems a bit nippier but that could just be the increase in RAM from 1.5GB to 2GB.
??

So, when ordering RAM, what's the trick to ensure you get matched 128-bit
capability? I missed the "gotta have stats".
From my experience, the biggest issues are:
1) same number of components (same chip count front and back)
2) same CAS latency
for example, in the numbers: PC3200U-30330
the first "3" in 30330 is the CAS latency. The other numbers after that can be different, but you want the CAS latency to be the same. I don't know what the other numbers mean.
PC3200 is just the type. Most likely you have the same type. Otherwise, you'd have other problems.
I've purchased, mixed and matched, and installed several different modules, and as long as they were the same CAS latency and chip count, they registered as "matched".
You can check the numbers for your modules by going into system Profiler, and clicking on the "Memory" in the list on the left.
System Profiler is in: Apple Menu --> About this Mac --> More info.
Hope this helps.

Pavilion dv7 blue screening - HP support assistant cannot test BIOS or memory modules but BIOS can?

About a month ago my dv7 started doing something strange - during normal use (not gaming, just word processing, showing a powerpoint presentation, showing a video on youtube, etc.) the cooling fan speed would suddenly ramp up to jet-engine speed and shortly thereafter the computer would blue screen, crash dump, etc. (no, I did not write down any info from the blue screen message - I will do so next time). Having experienced a blue screen issue with a Dell laptop I thought the hard drive was going bad, because about the same time I was suddenly unable to run a backup of the hard drive. After several attempts, I was finally able to backup the hard drive, and then replaced it with a new drive, re-installed OS with my recovery flash drive, worked through all of the windows updates that were recommended, and thought everything would be good to go. Now I have no problems backing up hard drive, etc. Then on day 2, after only a few hours of use, the cooling fan speed suddenly ramped up again and the blue screen returned.
A friend who is a tech suggested running HP diagnostics on everything, so I rebooted, hit F2, and started by testing the hard drive; as expected, no problems there. I next tried to test the memory (8192 MB total in two modules), and the test failed. I also tried testing the BIOS, and that too failed. The HP diagnostics reported that it couldn't even read the BIOS. Hmmm, strange. So I re-booted, hit F10, and went into the BIOS (BIOS date 10/5/11, revision F.1B). I HAVE NOT IN ANY WAY MODIFIED THE BIOS - I'm good, but not that good. Via the BIOS test utility, I tested both memory modules independently and then together, and everything checked out fine. I also tried switching modules between slots and re-tested via the BIOS utility, and that too checked out. I then returned to the HP diagnostics utility and tried re-testing the memory (both modules together - failed, one module at a time - both failed, in both slots).
HP tech experts, can you give me any guidance? This has been a great machine for me, I have taken good care of it, and am hoping to get a few more years out of it (I'm a middle-school science teacher, can't afford another one at this point). If I can't find a fix, I may have to go back to using my antique overhead projector in my classroom...

Hi @h20roks ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv7 and getting the BSOD and shutting down. I recommend to restore the BIOS defaults with this document selecting the reloading the BIOS default settings. Not rollback.
Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that could need updating.
Hope this helps you.
Thanks.

When I sync my Ipad when it goes to compatability testing it goes to an APPCRASH with exception code c0000005. What do I do to remedy this so the syncing is fully complete.

When I connect my Ipad to my laptop which uses Windows 7, the Ipad now appears to go through the sync process and then proceeds to the compatability testing where it crashes and stops (and for example new photos on laptop are not synced with Ipad). The problem event name is APPCRASH. Application name iTunes.exe. Fault Module name QuickTime.qts. Fault Module Versioni 7.70.80.34. Exception code c0000005.
What do I need to do to remedy this issue.

I googled the code and found it's a fault some system file in Windows 7 and needs to be fixed. Here is a link which offers two possible solutions. Personally, I'd go with option 2 and revert to an earlier date when you know you were able to sync without issue:

Has the duff memory module screwed my MB

I have a Neo2 Platimum AMD64 3200+ (standard heatsink)
Memory is Corsair CMX512-3200XLPT (2.2.2.5)
2x 512Mb twinX
Everything has been working fine for the last 2 weeks, but this morning the PC died
I was getting memory initialisation errors on the LED's
So I've now tested each memory module in turn in each of the dimm sockets.
Skt1(P) Skt2(G) Skt3(P) Skt4(G)
Dim 1 FAIL WORK FAIL WORK
Dim 2 FAIL FAIL FAIL FAIL
So It look's like the MB is broken and the memory too.
Could the memory module have stuffed up the Motherboard ?
The memory controller is on the CPU, could that have been affected ?
Has anyone else had this sort of problem ?
Andy Cooper

Not having any spare DDR memory I purchaced 128Mb dimm (PC2700) and proceeded to test the slots.
It worked in skt 2 and 4 (same as the working corsair memory module).
So I definitly have a fault on the motherboard and it also looks like I have a fault on one of the corsair dimms.
So either the MB killed the dimm or visa versa.
Looks like 2 RMA's in the offing

Memory Slot Utility "memory modules are installed in the recommended slots"

I've got two Mac Pros that give me this message. Every time I boot them up the Memory Slot Utility gives me the message that my memory modules are installed in the recommended slots.
This started after I installed an additional 8GB of RAM, bringing them up to 16GB. 8x2GB sticks.
I checked the login items and it's not there, so what else could I be missing?

I have this problem too on a Mac Pro Quad Early 2009.
Has 2x4GB + 2x1GB Runs fine with 10GB, but everytime I log in the memory utility pops up as if I have a problem.
How do I stop it annoying me?

Changing memory modules in Satellite M30X-165

The Notebook has two memory modules with 512 MB each module. I have received a used 1 GB module.
Can I remove one of the 512 MB modules and install the 1 GB module to get total 1,5 GB RAM or need both modules the same memory size?

According notebook specification you can upgrade your machine up to 2GB of RAM so you can use one 1GB RAM and one module with 512MB. Important is that you use 100% compatible memory modules.
Just for your info: compatible PC2700 1GB memory module has part number PA3313U-1M1G.
Make upgrade, test it and post some feedback.

Problem with memory module

The problem with upgrade memory module.
Available:
Cisco 2951 router with the default memory module 512Mb.
Additionally purchased:
Memory Module MEM-2951-1GB (SG572288FG8P6ILMH4)
Problem Description:
When you start seeing a hardware router modules, after loading the ROMMON
reading failure IOS image
The first module is worth the default 512M, 1G second unit acquired
The permutation modules as well as single use module 1G situation has not changed.
Work whether the module supplier sold me?

It shouldn't cost you a fortune, John. I usually find Apple re-sellers very obliging on matters like this. Where did you buy your memory from? If it was Apple retail they may help and explain about the residue at the same time.
It's not unusual to meet difficulties with the fitting of memory but the residue is something I haven't met before.

TS1587 I tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on you can hear the fan run, but the display stays dark. Any ideas what to do? Thanks Maja

My iMac won't start up, or wake from sleep. I've tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on, you can hear the fan run, but the display stays dark. Any ideas what to do? Thanks!

Mac doesn't boot
Can you hear the fans and hard drive and see the white boot screen? Flashing question mark? The circle just runs and nothing happens? Only black screen and nothing else? These can be very helpful to diagnose the source of the problem. [1]
Flashing question mark [2]: This is usually a sign of a failed hard drive. This indicates that boot up volume can not be found.
Black screen: This is usually a sign of a failed logic board. There is no single reason for this and this may be caused by failed GPU, screen, CPU or RAM.
Circle of death/no circle/blue screen: This is usually a sign of a hard drive failure. This may NOT be a dead hard drive, just broken permissions or something
Gray screen/Apple logo/spinning gear or globe/prohibitory sign/folder with flashing question mark [3]: This could be a sign of faulty hardware but more likely a software issue, i.e. broken permissions, failed software update, etc.
[edit]
What to do
First, hold down the option key (also known as the alt key) just after you've pressed the power button. This should show all the available options to boot from, so if you have Windows installed through Bootcamp or a disk in your SuperDrive, you should be able to see them along with your OS X drive/partition. Select the OS X partition with arrow keys and press enter. Startup key combinations
If that doesn't help continue doing the steps from below:
1. SMC reset [4]. Shut down and unplug all cables including power cord for at least 30 seconds and then plug in power cord and keyboard/mouse.
2. PRAM reset [5]. Hold down option, command, P and R while booting. Start it when you hear the sound and don't let go before it reboots.
3. Safe boot [6]. Hold down shift while booting to boot into safe mode. If this works, open Disk Utility from Utilities and repair your permissions and verify the disk
4. Hardware test [7]. Insert the install disk (disk 1 in Mac which shipped with OS X 10.5.4 or earlier, disk 2 if shipped with OS X 10.5.5 or newer) and hold down "D" before the grey boot screen opens. Follow on screen instructions
5. Boot from install disk. Boot from the disk that came with your Mac. Hold C while booting. Select Disk Utility from top bar and repair permissions and verify the disk. Reboot normally and see if it works now.
6. Boot from another Mac (Firewire target disk mode). Connect the machines with a Firewire cable. Power on your Mac and press T. Select the other Mac's hard drive. Download the current OS X combo update. Run the combo update installer and select the drive that won't boot as the destination.
7. "Repair" OS X. Boot from the install disk as in point 5. and reinstall OS X. This should NOT erase any data, just replaces the system files which may have caused your booting problem. Now install the latest combo update for OS X and repair permissions on your drive with Disk Utility.
7.1. Install OS X into an external hard drive and then boot from it [8] and try to copy your data from the hard drive before proceeding. If you have done a backup recently, you don't have to do this.
8. Restore OS X from Time Machine backup. Boot from the disk that came with your Mac and choose the Time Machine restore option. This step will lose any changes made since your last backup but the system and your data will be put back to exactly as it was on that date.
8.1 Reinstall OS X. Boot from the install disk as in point 5. and select Disk Utility again. Now erase the whole hard drive and install OS X again. If you had a Time Machine backup and step 7 worked you don't have to do this.

Crucial Memory gives me this module - is that correct?
http://www.crucial.com/uk/store/mpartspecs.aspx?mtbpoid=A332E10BA5CA7304
Found this via Kingstons site - is this also correct?
http://www.dabs.com/productview.aspx?QuickLinx=4P3V
Would really appreciate some official clarification here.
Many Thanks

It must be PA3513U-1M2G. You must check if this module is compatible with your notebook model. I think so.
Anyway I recommend you to buy high quality product like Kingston modules.

What's the right memory module for an iMac G4 Flat panel 15-inch?

Hello!
A new program I've recently bought requires me to expand my iMac's memory, which is currently 256 MB.
After searching the Apple Store web site, I think I've come to the conclusion that what I need is an Apple memory module called "512MB DDR266 SO-DIMM (PC2100), 200-pin". As I don't know any expert who can give me some advice, and as I'm no expert myself, could anyone please tell me if that's right?
Thank you!
iMac G4 Flat panel 15-inch Mac OS X (10.4.8)

Ciao e benvenuto alle discussioni di Apple.
There are actually 3 different types of user slot installable RAM for the iMac G4 models so you'll have to check what your processor speed is (Go to  Apple Menu > About this Mac > ):
iMac G4 15" and 17" 700 or 800MHz, PC133 144pin SODIMM.
iMac G4 17" 1GHz, PC2100 200pin SODIMM
iMac G4 1GHz 15" or 1.25GHz 17"/20", PC2700 200pin SODIMM.
So although I can't tell you exactly what RAM you need I can tell you that if you have a 15" screen the PC2100 is wrong.
I'd advise using Crucial memory in Europe as the prices are amongst the best and they are Mac friendly. I wouldn't recommend Apple memory; it's overpriced. I also wouldn't advise buying a cheap brand as it could cause trouble.
Here are the fitting instructions.
mrtotes

I am going to replace the memory module, will I loose the existing stored memory

I have a imac desktop with one memory module,, would like to insert 2 new memory modules,, will I loose stored memory

No. Nothing is stored in RAM when the computer's off, and you'll need to turn it off while upgrading its RAM.
RAM and drive space aren't the same. Back up the contents of the internal drive.
