Additional Ram Installation?

I bought the MacPro with 2 GB installed on 4 512 sticks, one pair up on riser A, the second pair on riser B.
I installed 2 additional GB's, as one pair as follows:
Riser A/DIMM 1 512 MB
Riser A/DIMM 2 512 MB
Riser A/DIMM 3 512 MB
Riser A/DIMM 4 512 MB
Riser B/DIMM 1 1 GB
Riser B/DIMM 2 1 GB
So is this optimal, as the heat seems pretty high in A1 most of the time, ~70C?

I have the same RAM as you have. I know that Apple suggest filling A1, A2, then B1, B2 Then A3, A4... Exactly as you did.
There's a site that suggest otherwise:

So my config is 4B. You can try it. The riser A has a higher temperature so if you put the 2 X 1Gig in riser A, the the cooling is easier since there is only 2 chips, letting more air go thru.

Lenovo G400 additional RAM installation

I have a LENOVO G400 laptop and added additional 2GB RAM from my previous ACER laptop. Aftern placing the RAM and turning on the power, my laptop screen display is blank. I dont see anything. But when i remove the RAM that I added, my laptop works fine. What seems to be the problem? Why wont it display anything when I add the 2GB RAM? Can anyone help me?

Hi gerardReeve,
welcome to the forums,
Maybe this is an incompatible RAM ? are you sure this 2gb ram stick is a DDR3 ?
Lets make 2015 the year of the #DO

T42 not recognizing additional RAM

I had to reformat my hard drive and in process of updating drivers. THe monitor image is very slow and I believe it may be due to the T42 not recognizing the additional RAM I had put in. Is there a way to download a driver for this RAM so it is recognized or another solution? Thanks in advance.

Hi and thanks. The screen is very slow meaning when in internet explorer and scrolling down a web page it sort of almost blurs. I initially though it was RAM but I was mistaken that on this particular T42 i didn't add any but just have the 500mb it came with. But I beleive something is causing the viewing to be slow. I just reformatted the computer so there is no programs running other than what is normal with XP installation. I played with the Display and brought down to 16bits 768 and it still slow on scrolling down any webpages.
The exact model is t42 - 2373 - h12.
I apologize for misdiagnosing but perhaps you might still know what the problem is? Thanks again.

Second internal HD, additional RAM & proper settings for them

Hi guy!
I want to thank you in advance for reading my questions and answering it. It may be long.
Today, I've received my memory upgrade 4GB (2X2) from OWC. And my 2nd hard drive Seagate Baracuda 500GB 7200.
I read all my the instructions and installed all memory and HD myself, all seams to be working, my system shows RAM and HD. However, there are some questions I have unresolved, I called tech support they couldn't tell me more than just "call the HD manufacture and ask them"
1st. After I've installed HD and started the computer, the window came and said that I need to initialize the HD. I clicked "initilialize" it took me to disk ut. I erased HD and gave it a name "Mac HD2" Now, it is showing me that I only have 465.64 GB of space available. It shows that only 108MB is used. Where is the rest? I know that it won't show the whole 500GB, but it ate up 35GB, itsn't that too much? So, my question about this is: Should I be doing something else with this HD? Should I be calling the company that sold HD and have them replce it? Or is it ok to hav such a loss?
2nd. What is the best way to place my folders & files on both HDs. I was thinking to take my Documents/Movies/Music/Pictures folders and just place them on HD2 and keep HD1 for applications only. Is this right?
3rd. My HD1 is 160GB (148.9 as per info.) My Documents/Movies/Music/Pictures folders are about 55Gb my application folder is 8 GB I should have about 86GB left (if we take 148-55-8) I only have 67. What am I missing? The user folder (yuriyork) is 60GB. I'm totally confused with where the space is.
With this said, I'm back to the 2nd question what files/folders I should move to HD2? I just want to do it right to try and up the computer performance.
4th. When I do move files/folders to HD2 should I just open HD1 and HD2 in finder and simply drug and drop folders from one window to another? I think it's not right way of doing it. I think I need to somehow specify to the system that Documents/Movies/Music/Pictures folders are now located on HD2
5th. With increase RAM, should I do any setting on OSX to tell it that there is lots of RAM and that it can use it as much as it wants? Like for example, I know that in Virtual PC I can set up the amount of RAM it uses. So, with that I thought that I may need to specify something like that in some other settings, if so than where?
I hope I didn't confuse you all with some much stuff. To hopefully simplify this, I'm going to put the JPG file on the web for you guy to see what folder are what size and may be give me an idea what is the best way to do it.
Here is the photo:
Again, thank you for taking your time to answer my questions, you guys have always been very helpful.
Thanks to all!!!

#1: The primary reason for the discrepancy is numbering convention. To hard drive manufacturers, a kilobyte is 1,000 bytes, a megabyte is 1,000,000 bytes, and a gigabyte is exactly 1 billion bytes, so 500GB is 500,000,000,000 bytes. Computers, using the binary system, don't use 1,000 to represent a kilobyte; instead they use 1,024.
Therefore, when you divide 500,000,000,000 by 1,024 (KB), again by 1,024 (MB), and again by 1,024 (GB), you'll get 465.66 GB, which is almost exactly what you're seeing.
#2: When I installed a second hard drive in my G5, I moved my Music, Pictures, and Movies folders to this drive. Then, I just had to point iTunes and iPhoto to the new directories. The sidebar links still take me to the original folders on the original drive, but that could likely be fixed if I replace the folders with an alias or symbolic link that pointed to the new location.
#3: Try downloading an app such as Omni DiskSweeper to help locate where all the space has gone to. It'll give you a breakdown by each folder and subfolder on the drive.
#4: As I stated in #2, an alias or symbolic link should work if you want the sidebar links to continue to function after moving the folders. Otherwise, just direct iTunes and iPhoto to the new locations.
#5: OS X manages memory on its own for each application. There's no longer the need to allocate RAM to each app like there was in the pre-OSX days.
When installing additional RAM, it's often recommended to reset the NVRAM to ensure that the computer recognizes all of it properly. To do this, reboot the computer while holding down the Command, Option, O, & F keys. This will boot you into open firmware. At the prompt, type the following (and press return after each one, of course):
reset-nvram
set-defaults
reset-all
The computer should reboot after the final command.

Installing additional RAM into hp s5150t

I have a quad core s5150. I recently tried to add two additional RAM modules. I verified that I had purchased the correct RAM on curcial.com and by speaking with their reps. The computer would not take the RAM in any configuration. We tried seating the new RAM into the old modules one at a time and it still would not work. At last, the crucial rep told me to try and update the BIOS. Hard as I tried, for three hours, I was unable to find the BIOS update on the HP website despite looking where the HP video told me to look. There were lots of update options but no BIOS heading. The auto detect tool could not identify my computer for some reason. The HP Update tool installed with the machine said no updates were available.
I am wondering a few things, 1) Where can I find the BIOS update on the HP site? It is not in the list of updates on this page, where it is supposed to be:
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4063&lc=en&cc=us&dlc=en&sw_lang=&product=4002...
2. Is it possible there is a problem or conflict beacuse the machine shipped with Windows Vista and I updated it to Windows 7? Looking in the BIOS, the last update was May of 2009, long befoe Windows 7 was updated from the old VISTA files.
3. Any other reason you might know for the modules to not be working? We exchagned them for a fresh set already and still the same problem. They are clicking into place. Not sure what to try.

Thanks for your support, Jaco. I appreciate your input.

Additional RAM needed

Trying to load new software, both of which tell me I need 1-2 GB of RAM. Where do I determine how much RAM I have, and can I simply buy and upload additional RAM to this model?
Thanks.

Hi
+"Where do I determine how much RAM I have?"+
Apple Menu > About this Mac.
+"can I simply buy and upload additional RAM to this model?"+
Yes. You buy RAM and physically install it. Depending on the model you may be able to do this yourself with an appropriate screwdriver or pay/get an authorised Apple Technician (or someone else who is capable of doing it) to do it for you. There's no upload involved.

Do I need additional RAM?

Hello to all,
Though I am not presently facing any trouble while editing, yet I am feeling discomfortable seeing the free space remaining on my 8 GB RAM which sometimes drops to less than 500 GB when I have just my internet and FCPX on. Do I have to go in for additional RAM?
Any guidance in this matter is most welcome.
DR.SOMANNA

If it ain't broke, don't fix it.
If everything works to your satisfaction you don't need it.
You may want it, but that's a different matter.
If you decide to get some, buy it from Crucial or Kingston, who provide the highest quality at the lowest prices . . . . just a fraction of the cost of getting it from Apple . . . . . and by "a fraction", I mean a quarter!

HT3918 Can I leave the installed 4gb (2 X 2gb) of ram in my iMac and add 8 gb (2 X 4gb) of additional ram to the available (empty) slots?

Can I leave the installed 4gb (2 X 2gb) of ram in my iMac and add 8 gb (2 X 4gb) of additional ram to the available (empty) slots? I will ultimately swap the remaining 2 X 2gb out for 2 x 4gb. If so, does this affect how the ram is used/accessed (i.e. will the original ram be limiting because it is in the installed location rather than in the other previously open slots?) Thanks.

That's exactly the RAM arrangement I've been running with for the last couple of years with no issues.
2x2gb on one shelf and 2x4gb on the second.

Buying additional RAM

I want to buy additional RAM for a brand new iMac.
1. Is there anything in particular I should be looking for when buying more RAM? Do I just get anything that says "1600MHz DDR3 SDRAM "? Is there a particular brand, etc.?
2. What is considered the going price for (2x8GB) for the new iMac?
Thanks.

1. Is there any advantage to the Crucial brand vs. OWC?
2. I want to buy the new iMac with the least amount of RAM possible 2x4GB, try it out, and add more RAM as needed. Is there a way to measure when I could benefit from the additional RAM? Some way to measure how much is being used while having Photoshop, Premiere, etc. running?
Thanks.

Anyone install additional RAM into your new MacBook?

I slapped a new 1 gig stick into my MacBook and noticed that after removing the bracket in front of the ram slots, adding new ram and putting it back that the bracket wasn't quite flush due to the pads that cover the ram slots, even after screwing the bracket back in. Anyone else experience this? I am just curious as to whether or not it is normal. When I removed the bracket initially to get at the RAM, I don't recall if the bracket was dead flat against the slots.

oh no, the RAM installed just fine. I am speaking to the metal bracket that covers the RAM slots and needs to be removed before installing ram. This bracket has cushions that cover the slots. When I put the bracket back on after installing the RAM, I was unsure whether or not these cushions should fit under the top of the RAM slots so that the bracket is flat after being screwed back in?
If you remove the battery and look at the RAM slots, is the bracket after RAM installation completely flat?

Installed Additional RAM - anything else?

I just installed an additional 512mb of RAM on my iBook, bringing the total RAM up to 1GB. The installation was pretty painless, but now I'm wondering: is there anything I should do to double-check the RAM to make sure it is working properly? On the 'About this Mac' page, it does show that my Mac now has 1GB of RAM, which is a good sign - but should I pursue anything else like a Hardware Test or the like just to be sure?

Usually, you'll be alright, but if things start acting odd, like your machine stops booting, etc. that's when you might start thinking there is something wrong with your RAM.
Until then, chill out and enjoy things.

W520 - Additional RAM?

I was considering purchasing an additional 4GB PC3-10600 DDR3-1333 Low-Halogen SODIMM Memory for my W520.
I am currently configured with Intel Core i7-2620 2.70GHz with 4GB RAM installed.
Can someone confirm this is possible and give me an idea of how to perform the installation?
Thank you in advance,

I just followed the manual and removed the two screws as it suggests. The keyboard came out with just a slight pressure with my fingers.
I would recommend you should only loosen the remaining screws if at all necessary.
W520 (4270 CTO) | i7-2820QM (8mb cache) | BIOS 1.40 | 1920x1080 FHD | Sensor |

Wallstreet and Tiger: no OS X 8GB "limit", issues if 512MB RAM installation

Since I felt that I could improve the performance of my [Wallstreet with Tiger|http://discussions.apple.com/thread.jspa?threadID=1390427&tstart=30], I decided to give a try to the break of the 8GB barrier as already reported in this forum so taking the occasion to substitute the 4200rpm 80GB disk with a 5400rpm one.
Again, acknowledgements to jpl, Tinkerman and others I do not recall for the helpful messages in the forum showing, if not else, that all this is possible. Unavoidable acknowledgements to the XPF developer too, of course.
I must admit that, while this time I was expecting a rapid installation after the method set out last time, actually I spent hours with any kind of issues of OS 9 either not installing or not booting even if from a disk cloned from the past working one. I was starting to think to some failed areas in the new disk but it appeared working in any other circumstance so eventually I realised that I was operating not only without the original CPU (Sonnet Crescendo 500MHz G4) but with 512MB of RAM and someone else already reported this as potential source of problems. Actually I realised it when, during one of the numerous serial attempts, the PowerBook remained with a black screen and suddenly produced the frightening "breaking glass sound", i.e. issues with the memory. Well, that was thrilling since I did not realise immediately what it was and I never heard it before...
So this time the method was the following:
- old disk removed from the Wallstreet and installed in a Firewire enclosure
- created three disk images on another recent PB G4 from the three partitions of the old disk (OS9, OS X, documents)
- new disk in FireWire enclosure, connected to the recent PB G4
- created two partitions in Utility Disk: 1GB HFS+, therestGB HFS+ Journaled
- installed new disk in Wallstreet
- reduced Wallstreet RAM to 256MB
- installed OS 9 from CD (and upgraded till 9.2.2) in the first 1GB partition together with XPF 4
- removed the disk and reinstalled in the FW enclosure
- cloned the old OS X disk image from the recent PB to the second big partition of the new disk
- reinstalled on the Wallstreet, started in OS 9, set XPF options as last time (Use Old NDRVs), boot in OS X
- copied all content of former third partition for documents in Documents
- restored the RAM to 512MB
Therefore the result is OS 9 in the first 1GB partition and OS X in the second 73GB and something partition. XPF mildly complained about the disk not having been formatted on OS 9 but setting OS 9 as helper was enough to satisfy it.
I am not 100% sure, say 95, but I have the feeling that, even after reducing the RAM to 256MB, the method to clone the old OS 9 partition to the new one did not work in the sense that the Wallstreet remained stuck at the question mark. Definitely it did not work with 512MB.
Summary (nothing new, just confirmations)
- OS X does not require to be installed in the first partition
- others (Tinkerman?) reported that this partition has to start in the first 8GB and not being included
- OS X partition can be more than 8GB
- watch out the RAM amount during installation (here it worked with 256MB but others reported 192 as maximum)
Hope this will help someone else.
Regards,
Giulio

Another installation procedure (still, similar to the previous one).
- reduce RAM to 256MB (some says 192 is better but now for me it was not feasible)
- with OS 9 CD: partition the disk,1GB/around 75GB, both HFS+ (there were few hiccups and I had to try more than once since the initialisation was failing and eventually I got a sort of ghost 5KB partition "for free")
- install OS 9 from CD to the 1GB partition
- update OS 9 to 9.2.2 through the installers
- mount disk in external enclosure connected to another system: initialise the around 75GB partition as HFS+ Journaled and cloned the old OS X partition to such partition (or install it for the ones that do not have such OS X partition ready)
- reinstall the disk into the Wallstreet and set up XPF (Use Old NDRVs); curious enough, here for the first time it said it could not boot from the second big OS X partition since it was "extending beyond the 8GB" or something similar still just choosing OS 9 as helper solved the issue
- restore the maximum RAM
- reboot in OS X
The OS 9 installation was done with the USB PCMCIA inserted and the USB mouse inserted in it. I do not know whether this was the solution (since also the previous time I selected all the USB additional extensions during OS 9 installation) but this time at the 9.1 update the mouse was recognised, not before, and it kept working since.
The Wallstreet just boots in OS X each and every time unless instructed to do differently through XPF.
The magnetic sensor issue still occasionally shows (apparently it needs "some time" or the Wallstreet just boots/wakes up nicely if just switched off or set to sleep). I will try to create some magnetic shield as already reported somewhere. Alternatively removing the two bays and waiting some five minutes or so does the trick.
What remains a bit unclear to me is the use of a magnet close to a hard disk, something I would consider the source of all evils if not properly done. I will study more, test and hopefully solve the issue.
Thanks,
Giulio
