Memory limitation on T61

I have the following Lenovo notebook :
Product: ThinkPad T61 8898-55G [change]
Operating system: All [change]
Original description: T7100(1.8GHz), 1GB RAM, 120GB 5400rpm HD, 14.1in 1024x768 LCD, Intel X3100, CDRW/DVDRW, Intel 802.11abg wireless, Bluetooth, Modem, 1Gb Ethernet, UltraNav, Secure chip, Fingerprint reader, 4c Li-Ion, WinVista Business 32
I configured my Notebook with a Dual-boot Windowx XP Pro SP3 and Windows Vista Bussines SP1 (32 bit)
I have 2x 512 MB PC2-5300 667 MHz DDR2 memory inside.
I read on the Lenovo site :
Memory Compatibility
(**) Windows Vista supports up to 4GB maximum memory (32-bit versions of Windows Vista cannot support 4GB). Windows XP supports up to 3GB maximum memory
I like to update my memory with
2x 40Y7734 1 GB PC2-5300 667 MHz DDR2
or
2x 40Y7735 2 GB PC2-5300 667 MHz DDR2
I like to know if I choose for 2x 2GB , will :
Windows XP SP3 work just fine only it works with 3GB instead of 4GB installed memory
Window Vista SP1 (32-bit) with the 4GB (even not supported) work stable ?
Because the prices of 1 GB and 2 GB won't change much nowadays.
I prefer to use 2x 2GB modules, but I like to know will it work (even with the memory limitation) stable on XP or on Vista
or it is better/safer to use 2x 1GB modules
Can anybody help/explain me or advice me ?

You're better off with 2x2GB, you may decide to run a 64-bit OS someday...and you will notice a difference between 2GB and 3GB when running a 32-bit OS.

Memory limitation for session object!

what is the memory limitation for using session objects?
venu

as already mentioned there is no actual memory limitation within the specification, it only depends on the jvm's settings
how different app-server handle memory management of session objects is another part of the puzzle, but in general you should not have problems in writting any object to the session.
we had the requirement once to keep big objects in session, we decided to do a ResourceFactory that returns us the objects, and only store unique-Ids into the session.
We could lateron build on this and perform special serialization tasks of big objects in the distributed environment.

HT5642 I need to update iOS 6.1.3 on my iPad2 to 6.1.6, due to security issue. Why is no update available? I do NOT want to install iOS 7, due to memory limitations.

I need to update iOS 6.1.3 on my iPad2 to 6.1.6, due to security issue. Why is no update available? I do NOT want to install iOS 7, due to memory limitations.

Any upgrade will be to the most recent, compatible version, in this case 7.0.6.

Standard Edition Memory Limitations

What is the upper memory limitation for the SGA size when using Standard Edition 9.x on Windows 2000?
What about Enterprise?

According what I know the SGA in one OS is limited by the OS and the parameter SGA_MAX_SIZE. I have never heard that SGA has limitations related to the license.
SGA_MAX_SIZE
Parameter type
Big integer
Syntax
SGA_MAX_SIZE = integer [K | M | G]
Default value
Initial size of SGA at startup, dependent on the sizes of different pools in the SGA, such as buffer cache, shared pool, large pool, and so on.
Parameter class
Static
Range of values
0 to operating system-dependent
SGA_MAX_SIZE specifies the maximum size of SGA for the lifetime of the instance.

DV6500 Physical Memory Limitation to 3gb

Hi All,
My DV6500 Entertainment PC came with Windows Vista 32-bit preinstalled which limited my usable memory from 4gb to 3gb. I recently upgraded to Windows Home Premium 32-bit which I believe has a physical memory limitation of 4gb (http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778%28v=vs.85%29.aspx#physical_memory_l... but upon inspection my windows still shows 3gb usable memory. Is there something I need to tweek in windows or bios to fully use all 4gb as installed on my laptop? Thanks in advance.
This question was solved.

Hi:
That's what this forum is for...asking and answering questions.
So there is absolutely nothing for you to be sorry for.
Unfortunately, there is no way you can re-map or re-dedicate the memory configuration. It is what it is.
However, your PC's BIOS may have a setting to allow for more dedicated graphics memory to be used.
I was very surprised to see that in my dv6810us BIOS, there is a video memory setting. The default is 64 MB. However, I could change the setting to 128 MB or 32 MB.
So, I changed it to 128 MB.

FPGA memory limitation

Hi...
I have tried to use more than 2 MB memory (using memory blocks) on FPGA. During compilation Xilinx tool chain generated error "AR #21955"....which is explained as memory limitation (in xilinx website). Can't we create memory blocks of more than 2 MB?? (or) all memory blocks size in a vi should not cross 2 MB??. I need to create arbitrary wave forms of milli/micro second precision for some minutes......so i need many no. of points to get required waveform....Is there any way to achive it....when I transfered each point from a RT vi (not on FPGA) it takes more time (to transfer data from RT vi to FPGA vi for every iteration).
Thank you,
Cheers,
Ravinder

The size of the memory blocks you can allocate in the project and use in your FPGA VI is limited by the size of the memory available on your FPGA device. This memory is in the range of 80-192 kB depending on which FPGA device you are using. Please check the data sheet or manual for your device for details.
http://sine.ni.com/manuals/
So unfortunately you will not be able to store the complete waveform on the FPGA device.
Your best option is to stream the waveform from host memory to the FPGA device using DMA and generate the data from the DMA FIFO in the FPGA VI.

Physical Memory limitation

I have an HP dv6448se that originally came with Vista x86
I have recently upgraded the OS to Win7 x64
The listed memory limitation of the laptop is 2048 (2GB)
What is it that limits the ram to 2GB? Is it a hardware thing, or was it an OS thing? Would the new OS recognize two 2GB chips, or am I stuck with two 1GB chips?

Memory limitation to load a Jpeg

Hi all,
I want to use the loader component to load an image within my
Flash lite movie, when I try to do it with a Jpeg (612pix X 792 pix
/ 96dpi X 96dpi), the device emulator says me in runtime:
Problem with content: 11 - Not enough memory available to
decompress
if I do the same with another Jpeg (533pix X 526 pix / 96dpi
X 96dpi) there is no problem.
My question is: what are the memory limitations to load and
to display an Image (Jpeg or bitmap)?

Hi Thamis,
Take a look at the flash.net.FileReference class here:
http://livedocs.macromedia.com/flex/2/langref/index.html
This is the built in Flash support for file upload. You'd
handle the upload with a servlet/jsp/etc. server-side component to
save it to disk or as binary data in a database.
Best,
Seth

System defined Shared memory limits

Hello,
I am in a situation where I want to determine the system defined shared memory limits in a process on Solaris 7.
Is there a system call or a library function which can serve this information on the system?
I want to avoid using system() function or popen().

Your problem seemed reasonable. What were you doing wrong?

Apple OS/X 10.4.1 Memory Limitations?

I just read this about Linux memory limitations this morning...
http://www.linux.com/feature/119287
How does Apples OS/x 10.4.1 fit into this picture? What are the OS defaults when it comes to memory? What are the equivalent commands that I could use to check and configure this?
Thanks in advance...

I'm not sure what you want to check. I'm not familiar with all the Unix commands, so I'm not sure if Unix has a command that tells you how much RAM you can install, especially because that limit is more one of the hardware than the OS.
If what you want to know is how existing RAM is being used then you can use Activity Monitor (Utilities folder) or the Unix command 'top'. Use the Terminal in your Utilities folder to run 'top'.

Memory Upgrade for T61

Hi friends,
I have a T61 7663-xxx system, with 1 GB PC2-5300 667 MHz RAM. My Front Side Bus is 800 MHz ( I think so!), Everest software reports my memory controller is dual channel capable, and ~ 85% physical utilization of RAM. I have a nVidia Quadro NVS 140M 128 MB graphics card, but Everest reports 512 MB ?
I would like to upgrade my RAM, and buy some online.
a) Should I buy a similar 2 GB PC2-5300 RAM for my system for performance boost, running Windows XP 32 bit? If so, should I buy Lenovo RAM only, for maintaining my 3 year warranty intact?
Only ThinkPad and Lenovo memory will assume ThinkPad and Lenovo notebook systems limited warranty
b) What are the other best alternatives for good quality, reliable laptop memory, besides Lenovo?
c) Would it be better if I am able to buy RAM which can match my FSB? Will this have any performance benefit? Do these similar FSB speed RAM exist?
Kindly suggest top memory makers, if any.
I could not find any Lenovo 800 MHz memory from their website.
Kindly help me solve my memory upgrade problem.
I am a mechanical engineering student, hence I don't have any idea about FSB and the like, so I request the learned members to cast light on this area.
Info about reputed online sites in US, with fast delivery will be very much appreciated.
Thanks in advance.

Hmm. As far as I know, the internal graphics card can't be upgraded. There's some dock you can buy that lets you add a graphics card for use with an external monitor, but I don't know much about it. The cpu is more likely to be upgradeable, but don't attempt unless you know a decent amount about hardware servicing. Also, make sure the cpu will be supported by the motherboard! Best not to buy one with a clockspeed higher than what Lenovo sold (core 2 duo at 2.6 ghz).
Why do you want to upgrade so much? I run 2.1ghz with discrete graphics and 2gb ram under Vista, and it runs beautifully. If you have integrated graphics, then that might be a bit of a pain, but hey, you've got better battery life!
Anyway, I'd look more into de-cluttering your computer to speed stuff up. Remove anything you don't need, especially Lenovo tools that run in the background and you may not need. Turn off search indexing (slower searches, but faster overall performance). There are some nice guides online, if you google "vista tuneup."
Good luck! Enjoy your T61 as it is! It's a lovely laptop

Intel Turbo Memory 4GB on T61 ICH8M Controller

The little 1GB Turbo Memory on my 4GB RAM system was of little use. So I had the great idea of buying the 4GB Turbo Memory card so I could use User Pinning. Unfortunately, I didn't read that it only works with the ICH9M Serial ATA controller - my system has the ICH8M controller (which only works with the 1GB module).
Now I've got the 4GB Turbo Memory module installed but neither ReadBoost or ReadyDrive are usable.
Does anyone have any ideas/suggestions now to make this work? It's a type 6459 T61.
Thanks
Herschel

In Thailand, There's someone that can use ITM4GB with T61, ICH8M chipset but It can use ReadyDrive only (ReadyBoost not work!).
You may try this step
1. Update Intel Matrix Storage Manager Driver at http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-70477
2. Double Click Install will extract files to C:\DRIVERS\WIN\IMSM\PREPARE
3. Double Click at install.exe
4. Restart, press and hold F1 key and Config Sata -> ACHI
5. Save & Exit Restart & Give a try
With ITM4GB, you can use ITM Dashboard to configure application you want to ITM load, so these app will run faster and they also claim that battery usage time is up about a hour. I don't know it will work for your case or not. Good Luck...

Memory limitation on MBP

To call myself a Mac newbie would be a severe understatement. This is my first post/question. I am considering my first Mac (can't take another day with Vista!). In researching, I was surprised to find that the MBP max's out at 4GB of RAM. Is OS X a 32-bit OS and, therefore, unable to address more than 4GB? Is OS X much more memory efficient that Windows? I do plan to use VMware to run virtual machines on the MBP, so that's a concern as well. Do I need to be worried about this hardware limitation?

leopard osx is 64-bit http://www.apple.com/macosx/technology/64bit.html
the 4gb limit in the current mbp is just apple's design decision
i use vmware, in 4gb i run two virtual appliances, and ubuntu, and zeroshell, together with various things on the mbp
these may interest you...

Memory limitation on 32-bit Server 2000 pltfrm

Looking for the definitive explanation of why/what is limiting the ability to allocate more than 1/2 of the available system memory to Oracle SGA & PGA. Specifically: 4GB total system RAM on a MS Server 2000 32-bit system platform. Unable to appropriate/allocate more than 1/2 (2GB) of memory to Oracle 9.2.0.4 processes - SGA & PGA. I've read some discussion that Windows appropriates certain amounts - perhaps half - of all available RAM on 32-bit systems. e.g. 2GB total RAM results in 1GB to Server 2000 system processes and 1GB available to Oracle. Is this thinking on the right track.
Need Oracle to utilze more memory. Can anyone offer or point to an explanation of this limitation..... a work around
Thanks,

Following an excerpt of Note 225349.1 in MetaLink
"Implementing Address Windowing Extensions (AWE) or VLM on Windows Platforms"
AWE Memory implementation on Windows 2000
A common question on the Windows NT/Windows 2000 platform revolves around
how to take advantage of systems with more than 4 GB of RAM. As discussed
in Metalink NOTE:46001.1 and NOTE:46053.1, the 32-Bit process address
space for any process on Windows equates to a total of 4GB of addressable
RAM. Of this, by default, 2GB is reserved for the process itself, and 2GB
for the kernel. On systems running either Windows 2000 Advanced Server,
or Windows NT 4.0 Enterprise Edition, this ratio can be changed by adding
the /3GB switch to the boot.ini, allowing a process to address 3GB and
reserving 1GB for the kernel. However, the total addressable memory for
a single process is still only 4GB.

Memory Limitation on EXPORT & IMPORT Internal Tables?

Hi All,
I have a need to export and import the internal tables to memory. I do not want to export it to any data base tables. is there a limitation on the amount of memroy that is can be used for the EXPORT & IMPORT. I will free the memory once I import it. The maximum I expect would be 13,000,000 lines.
Thanks,
Alex (Arthur Samson)

You don't have limitations, but try to keep your table as small as possible.
Otherwise, if you are familiar with the ABAP OO context, try use Shared Objects instead of IMPORT/EXPORT.
