HT1270 maximum amount of memory

what is the maximum amount of memory i can install in a 15" 2012 macbook pro

Welcome to the Apple Support Communities
The Mid 2012 MacBook Pro supports 8 GB of memory officially, but you can install 16 GB of memory. You can buy memory in OWC or Crucial > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_160 0MHz_SDRAM

What is maximum amount of memory that oracle db can utilize ?

Hi
Thank you for reading my post
What is maximum number of memory that oracle database can utilize for each of its memory structure like sga, caches....
Thanks

ps, the following may help too
VLM) Configurations
Oracle Database for Windows supports Very Large Memory (VLM) configurations in Windows 2000, Windows 2003, and Windows XP, which allows Oracle Database to access more than the 4 gigabyte (GB) of RAM traditionally available to Windows applications.
Note:
This feature is available on Windows 2000, Windows 2003, and Windows XP only with Intel Pentium II and above processors.
Specifically, Oracle Database uses Address Windowing Extensions (AWE) built into Windows 2000, Windows 2003, and Windows XP to access more than 4 GB of RAM.
The requirements for taking advantage of this support are:
1. The computer on which Oracle Database is installed must have more than 4 GB of memory.
2. The operating system must be configured to take advantage of Physical Address Extensions (PAE) by adding the /PAE switch in boot.ini. See Microsoft Knowledge Base article Q268363 for instructions on modifying boot.ini to enable PAE.
3. It is advisable (though not necessary) to enable 4GT support by adding the /3GB parameter in boot.ini. See Microsoft Knowledge Base article Q171793 for additional requirements and instructions on modifying boot.ini to enable 4GT.
4. The user account under which Oracle Database runs (typically the LocalSystem account), must have the "Lock memory pages" Windows 2000 and Windows XP privilege.
5. USE_INDIRECT_DATA_BUFFERS=TRUE must be present in the initialization parameter file for the database instance that will use VLM support. If this parameter is not set, then Oracle Database 10g Release 1 (10.1) or later behaves in exactly the same way as previous releases.
6. Initialization parameters DB_BLOCK_BUFFERS and DB_BLOCK_SIZE must be set to values you have chosen for Oracle Database.
Note:
The total number of bytes of database buffers (that is, DB_BLOCK_BUFFERS multiplied by DB_BLOCK_SIZE) is no longer limited to 3 GB.
Dynamic SGA and multiple block size are not supported with VLM. When VLM is enabled, the following new buffer cache parameters are not supported:
o DB_CACHE_SIZE
o DB_2K_CACHE_SIZE
o DB_4K_CACHE_SIZE
o DB_8K_CACHE_SIZE
o DB_16K_CACHE_SIZE
o DB_32K_CACHE_SIZE
To select the block size for the instance, use the initialization parameter DB_BLOCK_SIZE. The buffer cache size is set by the initialization parameter DB_BLOCK_BUFFERS.
7. Registry parameter AWE_WINDOW_MEMORY must be created and set in the appropriate key for your Oracle home. This parameter is specified in bytes and has a default value of 1 GB. AWE_WINDOW_MEMORY tells Oracle Database how much of its 3 GB address space to reserve for mapping in database buffers.
This memory comes from the 3 GB virtual address space in Oracle Database, so its value must be less than 3 GB. Setting this parameter to a large value has the effect of using more of the address space for buffers and using less AWE memory for buffers. However, since accessing AWE buffers is somewhat slower than accessing virtual address space buffers, Oracle recommends that you tune these parameters to be as large as possible without adversely limiting database operations.
In general, the higher AWE_WINDOW_MEMORY is set, the fewer connections and memory allocations will be possible for Oracle Database. The lower AWE_WINDOW_MEMORY is set, the lower the performance.
8. Once this parameter is set, Oracle Database can be started and will function exactly the same as before except that more database buffers are available to the instance. In addition, disk I/O may be reduced because more Oracle Database data blocks can be cached in the System Global Area (SGA).
Note:
Registry parameter VLM_BUFFER_MEMORY, which enabled VLM configurations in earlier releases, is not supported in Oracle Database 10g Release 1 (10.1) or later.
VLM Instance Tuning
VLM configurations improve database performance by caching more database buffers in memory. This reduces disk I/O compared to configurations without VLM. VLM support in Oracle Database 10g Release 1 (10.1) or later has been re-written to integrate very closely with Windows. Compared to Oracle8i release 2 (8.1.6), VLM users should see better performance with the newer implementation.
Tuning for VLM is no different than tuning for configurations without VLM. It is an iterative task that begins by selecting appropriate DB_BLOCK_SIZE and DB_BLOCK_BUFFERS initialization parameters for the application being supported.
Note:
Oracle Database 10g Release 1 (10.1) or later VLM configurations do not support multiple database block sizes.
AWE_WINDOW_MEMORY, a new registry parameter specific to VLM, tells Oracle Database how much of its address space to reserve for mapping in database buffers. It defaults to a value of 1 GB, which should be suitable for most installations. If DB_BLOCK_SIZE is large, however, the default AWE_WINDOW_MEMORY value of 1 GB may not be sufficient to start the database.
Increasing the value of AWE_WINDOW_MEMORY will improve performance, but it will also limit the amount of memory available for other Oracle Database threads (like foreground threads). Clients may see "out of memory" errors if this value is set too large. As a general guideline, increase the AWE_WINDOW_MEMORY registry value by 20 percent.
For example, if DB_BLOCK_SIZE is set to 8 KB, AWE_WINDOW_MEMORY is set to 1 GB, and the number of LRU latches is set to 32 (16 processor computer), then database startup fails with out of memory errors 27102 and 34. Increasing the value of AWE_WINDOW_MEMORY to 1.2 GB fixes the problem.
Having a large cache in a VLM configuration may also slow down database writer (DBWR) threads. Having more DBWR threads will distribute work required to identify and write buffers to disk and will distribute I/O loads among threads. Initialization parameter DB_WRITER_PROCESSES enables you to configure multiple database writer threads.
A large cache can also introduce contention on the LRU (least recently used) latch. On symmetric multiprocessor (SMP) systems, Oracle Database sets the number of LRU latches to a value equal to one half the number of processors on the system. You can reduce contention on such configurations by increasing the number of LRU latches to twice (or four times) the number of processors on the system.

Windows 4 GB RAM Tuning (4GT)
The following Windows operating systems include a feature called 4 GB RAM Tuning (4GT):
· Windows Server 2003
· Windows 2000 Advanced Server
· Windows 2000 Datacenter Server
This feature allows memory-intensive applications running on Oracle Database Enterprise Edition to access up to 3 GB of memory, as opposed to the standard 2 GB in previous operating system versions. 4GT provides a tremendous benefit: 50 percent more memory is available for database use, increasing SGA sizes or connection counts.
Large User Populations
Several features allow Oracle Database to support an increasingly large number of database connections on Windows:
· Oracle Database Shared Server Process, which limits the number of threads needed in the Oracle Database process, supports over 10,000 simultaneous connections to a single database instance.
· Oracle Net multiplexing and connection pooling features allow a large configuration to connect more users to a single database instance.
· Oracle Real Application Clusters raises connection counts dramatically by allowing multiple server computers to access the same database files, increasing the number of user connections by tens of thousands, as well as increasing throughput.

Maximum amount off memory?

Ok ive done some searching and find some people saying the macbook max out at 2gb some say 3 and others say 4. Im buying a new macbook in the very near future and will probably just upgrade the memory myself. I know running dual cards with the same amount (ex 2x2gb) will give best performance but I just need the maximum. Thanks in advance
PS - Im buy the black macbook if that makes a difference

It depends on the MacBook model. The current model, introduced in late 2007, can handle up to 4GB of RAM. The previous models can accept up to 3GB, though Apple's official specifications only state 2GB.
And no, the black is strictly cosmetic. There are no technical differences between the white and black models.

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).
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007609%20600000410%20600213067&IsNode...
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.

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.

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...

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 DDR400 mem on MS-6728 board

I was wondering if my MSI 865Pe Neo2-LS board is able to work with four modules of 1Gb DDR400 memory in dual channel mode without reducing the speed automatically to DDR333 (some websites indicate this).
In "Test Results" on the support page of my mainboard is this configuration not tested. Only 4x 512Mb is tested, but the MS-6728 supports up to 4Gb.
This matter is important to me because I want to upgrade my memory (which is currently 1Gb) to 4Gb.

How cone?
It is Vista 32bit (my CPU is 32bit --> P4 3.0GHz Northwood core) by the way.
Can I install Vista 64bit onto a system working with a 32bit CPU and thus use the full 4Gb?
A certain amount of memory is taken by the bios for hardware memory addressing, the limit for physical memory seen by a 32bit Operating System is 3.25Gb, the rest is taken by Bios.
Ok, so if you wish to go ahead with 4Gb's fine. The price of DDR1 memory is 3 times as much as DDR2.
You will have to adjust memory manually in bios, for the 4GB to work.......disable SPD and set timings & the voltage. Value or Generic will be a 50/50 chance.......
No you cannot use a Northwood with a 64Bit OS..... going to 64Bit is a big hassle, great if you know your hardware and can access drivers to support hardware. Very bad if, no 64Bit drivers available or never will happen..... (Creative Labs)

Amount of memory not stable

i know that using certain type of OS with a CPU can result in lowered amount of memory
i updated the mainboard using "liveupdate"
Mainboard : MSI 990 FX GD-80
OS : windows 7 ultimate 64 bit
CPU : FX 4170
Memory : 4x4 GB 2133 MGHZ
PSU : XION 1000(W)P14F
all BIOS settings remain default and it result in such behavior
the memory randomly go from 4 GB to 16GB when i booted until i restart it
i've never overvolted my memory sticks
DRAM frequency is auto
my DRAM voltage is auto
and timing is auto
my programs doesnt crash
i think it might be timings.. cuz i checked voltage from various programs and it seem okay
and when i undervolt it(just a little bit).. programs crashes

i found the spec on the webpage of the memory manifacturer -> http://www.mushkin.com/Memory/Blackline/997015.aspx
Q: if it did that before live update...
A : lol i dont know seriously.. the first thing i did is update
http://imageshack.us/photo/my-images/831/meht.jpg/
http://imageshack.us/photo/my-images/819/spdj.jpg/
ok ill bump it from 1.52 to 1.54
Q: if i bought that in a kit of 4
A : i bought 2 kit of 2.. infact..lol but its the same models
** edit
infact the problem is not that if its seen or not.. its like..
i recently boot up and it seem i can only access 1 dimm of memory
because apparently 12 GB is allocated for hardware and the BIOS or something

Amount of memory cunsumed by iView

Hello experts,
Could you please tell me the amount of memory consumed by an iView?
Of course the amount is affected by the contents, but here I am asking about the iView itself.
I need to estimate the memory consumption amount necessary to load a page in EP.

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.

Firefox 8 is using massive amounts of memory, currently 2 G with only a few tabs open.

I just upgraded to Firefox 8, but it is using such enormous amounts of memory that my computer has slowed to a crawl. According to Task Manager, memory usage is now down to 1.3G but still that's so much that it's hard to see what I'm typing. The previous versions of Firefox didn't use nearly so much. If this can't be fixed, I will have to use Google Chrome or IE even though I much prefer Firefox. Closing tabs in Firefox maxes out CPU usage, and this is a new computer with lots of memory. I think this is a bug. I don't want to have to go in and disable features that I have been using. Can you tell me when there will be a fix for this?

I'm running Firefox 8.0.1, no add-ons, no themes, no bells or whistles. Firefox takes up large amounts of my memory and brings my computer to a crawl. I'm well educated in A+ Network+ and Cisco CNA I am by far a very educated user and can not solve this problem myself.
I hate to say it, but Firefox is slipping in quality and I may have to switch to Opera if this problem can not be resolved. It's been an issue since v.5 and continues to be a pain.
