Maximum amount of supported RAM by the OS

Hi,
My Macbook pro currently has 4GB of RAM. I have another 4GB RAM module which I would like to install. But I have read from some non-apple site that the operating system supports maximum 4GB. Is this true?
Will it be able to utilize the additional 4GBs of RAM (total 8GB) efficiently ?
Thanks

Hiya.
The maximum memory is not determined by the OS but by the hardware. For example if you had a MacPro 8 core Xeon, you could have 32 GB of ram. The max you can install on your MacBook Pro is 4GB (2x2GB).

Maximum Amount/Defult Value as per the company in Travel Exp Type

Hi Experts,
I want to maintain the Maximum amounts/Default values as per the company code in Travel Expense Types. Can any please suggest me whether is this possible if yes how.
Thanks

Hi Srinivas,
Follow the below path:
SAP Customizing Implementation Guide > Financial Accounting (New) > Travel Management > Travel Expenses > Master Data > Travel Expense Types > Define Maximum Rates and Default Values for Expense Types.
Maintain your rates here per expense types.
Note that you cannot maintain per company code here, you have to maintain per Trip Provision Variant. In Travel Management, most of the settings are per trip provision variant and not per company code.
Hope this helps.
Best Regards,

Supported RAM in the new MacBook Pro

On Black Friday last year I purchased 8gb of RAM for the current MacBook Pro. Will this RAM be supported in my new MacBook Pro that I ordered right after the refresh Thursday?

You are best off to buy the specified new Ram modules 1333MHz DDR3 SDRAM.
Mac is finicky about RAM. Yes you could install your old RAM but I suspect out of nowhere in a week you will be wondering why all of a sudden you have a Kernel Panic. Just buy the correct RAM.
Send along the old RAM (1067 MHz DDR3) with your old MBP when you sell it.

Is There a Maximum Amount of RAM Loaded Per Core on the Processors

I hope I'm asking this question in the correct group.
We use AutoCAD Civil 3D which only uses one core of a multicore processor.
We seemed to have reached an impasse with AutoCAD and Windows with RAM usage. It appears that Windows will only load a maximum of 15.8GB RAM into the first core of a Intel Xenon or Intel I7 processor.
We have a rather large drawing that is roughly 48GB in size. This drawing opens on all the tested systems in about 33 minutes on a xenon system with 16 GB RAM, xenon system with 32GB RAM, I7 system with 32GB RAM and an overclocked I7 system
with 64GB RAM. The OS is Windows 7 64 bit and Windows 8.1 Pro.
Watching the resources on all the machines during the drawing opening the network throughput varies from 100Gbps to 500Gbps and when the first core reaches a maximum of 15.8GB RAM the throughput drops to around 72Kbps! These results are almost identical
on 4 different setups with RAM ranging from 16GB-64GB.
The 16GB system pulls all available RAM, 32GB and 64GB systems would only pull at the most 15.8GB to the first core.
Is this 16GB core limitation a Windows issue or an AutoCAD issue? AutoCAD is telling us we may have reached the core limit in windows.
Regards.

Hi，
As I know, there are 3 factors that limit the highest RAM amount your computer is able to see: 32 bit or 64 bit CPU, RAM limit of OS and RAM limit of motherboard. for CPU, 32 bit CPU can only has a limited 4 GB RAM, while 64 bit windows can has more RAM,
depends on the Windwos Version (you should also exclude some RAM used by audio\video\network memory). and motherboard manufacturer is the important one who decides the maximum RAM amount that can be supported, the only sure way to know is to consult your motherboard
manual\view the manufacture website\contact the manufacture.

Credit receipt exceeds Maximum amount allowed

Hello,
We were recently requested to update one of our expense type's "Default/Max. value", also we were requested to have the "Amount type" set to "Error message for exceeding maximum". We have now come across a problem where credit receipts that are uploaded to our system are above the maximum amount allowed and are receiving the error message, these receipts cannot be itemized with personal expense down to the maximum because of the error message, so the users are having to enter these receipts in manually.
Is there a way to keep the error message for the maximum value and be able to itemize the receipt even if the receipt is above the limit?
- Edward Edge

hi
no you cannot.
the only way you can change the system error message as warning and proceed.

Maximum amount of messages allowed

Please advise what is the maximum amount of messages allowed during the Automatic Message Propagation in Intranet applications.

Are you sure this is a report, and not an extract? If it's an extract there are better tools to use for the job. (SSIS perhaps?)
If you must run it through SSRS, you'll need to shrink your columns widths down to 454.5 / Number of Columns.
It might be worth considering displaying the data the other way, too.

What is the maximum amount of RAM I can install in a late 2011 Macbook Pro 17"?

What is the maximum amount of RAM I can install and will be suported in a late 2011 Macbook Pro 17"?
Thank you,

Although Apple states a maximum of 8 GB, OWC (macsales.com) has tested 16 GB, so if you want to install 16 GB, I'd go with OWC as they tested it and do guarantee their RAM to work with Macs.

Whats the maximum amount of ram and storage space i can fit into my 13" matchbook pro (early 2011)

I am looking to upgrade my mackbook pro and was wondering what's the highest amount of ram and maximum amount of hard drive space i can get.
also whats a good brand i should use for both ram and hard drive.

I like Hitachi (HGST) and have 6 of them in my inventory. I never had any WD drives and there are some who do not speak well of them who's opinions I respect.
I also have many Seagate HDDs and currently have 1 TB Seagate SSHDs in my MBPs. They are performing satisfactorily.
Ciao.

Maximum amount of RAM on Y570 and Z570

What is the maximum amount of RAM that the Y570 and the Z570 can support? Is it 8GB or 16GB?

velenoso666,
I think you are all right - this is peer to peer support, and customers / non-employees who participate here do provide the vast majority of the answers. I think that is actually a really good thing, and it makes sense if you think about all the different possible scenarios - combinations of various software, OS versions, 3rd party option accessories, and environments being used.
Indeed, I think Lenovo does learn from our customers in many ways, and I think that is a good thing too. I continue to be impressed by the kinds of people here - many who are engineers or professionals with advanced degrees, some like AndyP who work on our systems on a daily basis (and have for years) based on their "day jobs" , and some who may just be brilliant on their own account.
In terms of providing "official answers" when it comes to specs, we have to answer based on reference doccuments - PSREF sheets, content on support or marketing site (except when a mistake is noted there).
When it comes to memory or HDD compatibility - the official answers are what is published, and those come from a combination of the test plan and the products that we sell at the time the spec was published. For example, if we didn't sell an 8 GB module, it may well work, but we may not have tested. We have to provide an answer for what we are prepared to support through engineering.
In many cases, the community may report that things actually do work in configurations beyond which Lenovo offiicially supports, and I think that's a good thing too. Another value for having our customers pool their knowledge and experience here.
Thanks for your feedback and suggestions / knowlege you share with others here.

Maximum Amount of Ram

I recall reading, somewhere, something that gave me the impression that there was a limit to the total amount of RAM that one can have in a MacBook Pro, and any computer really.
Is this true? And if it is, how can I tell what the maximum amount is that I can put in my computer, or if someone can simply tell me, that works too.

A recommendation for your consideration:
3rd Party sources have you remove the one or two 4Gig cards you have now in your MBP and replace with one(1) with their 8Gig card or two (2) of their 8Gig cards for a total of 16Gigs.
MBP has only 2 memory card slots on 17" MBP (early 2011)
Higher density RAM will be available hence even higher RAM options in the near future.
Big time question would be :"is this an appropriate "upgrade" from a cost-benefit perspective"!!
One wants to optimize NOT maximize in all choices.
Let 'er rip and...

The Maximum Amount?

Thanks to several users, 90% of my Mac problems have been solved and both of my Macs have been running smoothly for nearly a year now.
I currently have an iMac 17" (G4) from 2004 that runs smooth as butter. But the one I use most of the time is my MacBook Pro 15" 2.16 GHz Intel Core Duo. It was bought refurbished Winter 2006 and had 1 GB of memory installed.
There's still one empty slot in my Mac and I just bought the game Spore and would love to be able to run it at (close to) Maximum settings.
I have read that the maximum amount of memory my particular model can take is 2 GB. But I believe I have seen 2 GB RAM (on one card) being sold for my model.
So my question is this: is the maximum amount of memory for MY particular model of MB Pro limited to 2, 3, or 4 GB?
I've also read that www.datamemorysystems.com is a reputable seller.
Thanks for any replies!

I've also read that www.datamemorysystems.com is a reputable seller.
To add my two cents--for the last five years I have bought the majority of my RAM from DMS with the remainder being from OWC. I find the DMS RAM finder system to be helpful and easy for inexperienced buyers to navigate, and I've yet to find incorrect information.
Only once did I have trouble with DMS RAM and it was due to an oddball pickiness on the part of an old G3 PowerBook. DMS worked with me to get past the issue.

I just bought a docking station for my iPad so I could plug into a mixing board and record a live show. I was disappointed at the time limitation for the recordings. What is the maximum amount you can record a song into GB for the iPad?

I purchased a docking station for my iPad so that I could record a live recording of my band directly from a mixing board this weekend using GarageBand. Unfortunately, I was unaware of the song length limitations of the iPad version of this program. Basically, was unable to capture more than 15 minutes of the gig. I've read other conversations on this forum and can't really determine the maximum amount of time this application can record. Can anyone tell me how long GarageBand for ipad can record at one single time and how to adjust the settings to achieve this? Also, is anyone aware of any other apps than could be used to record a longer please share. Thanks.
CP

I received an email reply from George, the Founder and CEO of Studiomini, he indicated to me that their app does not have any time limitations in regards to recording like GB does, you are only limited by the amount of free space on your iPad. Fo what it's worth, I think the Alesis IO Dock is an amazing piece of equipment. I would highly recommend purchasing the IO Dock and plugging your mixing board into the dock to capture your rehearsal. Hopefully the feedback I received from Studiomini is accurate and I can capture my entire rehearsal at one time. I hope this feedback helps. One last note, apparently their will be a update soon to view Studiomni in the landscape view on the iPad instead of just the portrait view.

What is the maximum amount of memory my laptop can have?

I have a HP Pavillion DV6-7028tx with WIndows Home Premium installed, and I was wondering how much memory i can upgrade to?
The hp website says that 8gb is the maximum that it can handle, but the Corsair system scanner says that it should be able to hold a total of 16gb.
I've read that the maximum memory home premium can have is 8gb, so does that mean that if I upgrade to proffesional, I will be able to have 16gb?
Also, if I upgrade the memory myself, will it void my warranty?
This question was solved.

Hi:
Below is the link to the service manual for your PC.
http://h10032.www1.hp.com/ctg/Manual/c03216834.pdf
Supported memory can be found in chapter one, page four.
The specs page shows 8 GB but that is contradicted by the manual. Plus you got confirmation from the corsair scanner that can run 16 GB in your machine.
What does it say about the FSB speed? The manual states you can run PC3-1600 (PC3-12800).

W7 Home Premium will recognize up to 16 GB of memory so you do not have to upgrade the OS. Only beyond 16 GB would you need to go to W7 Pro.
You will not void the warranty if you read the service manual and follow the procedures for installing the memory, unless of course you fat finger something and physically damage the hardware.
The memory you install will not be covered under HP's warranty of course, but most quality memory carries its own lifetime warranty.
