PowerPC G4 MDD Maximum Memory Allowed
Can't seem to find the information I'm looking for. I wanted to know the max of ram I can put in a PowerPC G4, and the type ...
The machine currently has PC2600-25330 DDR SDRAM 4 at 1g. Just curious if there was anything faster I could put in there.
Thanks

yep 2G's is the limit.
the MDD can have 2GB max.
I have 4x 512MB PC2700 DDR333 CL2.5 SDRAM DIMM's in my Mac.
always kind of funky when I see Apple System Profiler show them as PC2600. But oh well the computer runs!\
just be glad there isn't anything like RAMDoubler for OSX. LOL just got me going down memory lane to my old 68K days, stupid Performa with max of 52MB RAM, used RAMDoubler to make it think it had 104MB. hee hee hee...

Is there a Web site or Web tool that I can use to check the amount of maximum memory for my MacBook Pro?
Welcome to Apple Support Communities
Of course. The Crucial Memory Advisor Tool allows you to look for your Mac model and it tells you the maximum RAM you can install > http://www.crucial.com -
Hyper-V, Dynamic Memory, Memory Demand more than Maximum memory
Hi,
I have found that for some VMs Demand Memory more that Maximum Memory set.
Where can I found any documentation about this?A VM can 'demand' more memory than is possible'
But it will never actually be given more then the maximum.
In the VM the application is asking for more RAM from the virtual memory manager of the OS in the VM (not to be confused with any memory management that the hypervisor is doing).
When the VM hits its Maximum setting it is no different than a physical machine hitting its physical RAM cap - the OS begins paging to give the application the additional RAM it is asking for.
It simply means that you have a greedy application. SQL and the Exchange mailbox role have a long history of being very greedy applications (SQL made many changes to work in concert with dynamic memory) - taking all of the RAM they could get.
In your case, you have a startup of 32GB a minimum of 24GB and a Maximum of 36GB. And the application in the VM would 'like' to have 54GB. If you look in your VM OS you will probably find that it is paging to disk.
What is your allocation setting? The default of 20% Higher?
Personally - I see little value in using dynamic memory with such a small window of difference between the startup, minimum, and maximum. It is as if you are trying to micro manage the feature, instead of allowing the feature to work as designed.
Dynamic memory is designed to balance RAM between all of the VMs on a particular hypervisor at the same time. And to allow use of all the RAM the machine has, if there is a workload that can use it. If the VM wants 64GB, why not give it that.
Dynamic memory will not starve other VMs to give this VM more RAM (unless you give this VM a higher priority). But it will take RAM away from a VM (if absolutely necessary) to allow another VM to meet its requirements.
Any VM is always guaranteed its startup, at boot time. And dynamic memory will not starve it below it minimum - and if the VM is not using RAM it will take RAM away down to the minimum. And a VM will never be given more than the maximum, even
if the VM wants more.

Is there a maximum memory allocated?
Dear all,
Anyone knows if there's a limitation to the maximum memory
that labview can allocate in Win98?
I cannot allocate more than ~ 19500 KB and my computer has
1GB.
Cheers,
ErnestIt seems it is a problem with the working set size and locking of pages. We have developed under Win2000 and have a double buffer daq application. The problem was the application was too late in the loop to get the data from the driver so it gets overwritten. Think of calling AI Read in a loop and the loop stopped for some time.
I suppose you have no documentation for the windows API so I give you some from the MSDN.
VirtualLock is the function which locks memory into RAM.
"The VirtualLock function locks the specified region of the process's virtual address space into physical memory, ensuring that subsequent access to the region will not incur a page fault.
All pages in the specified region must be committed. Memory protected with PAGE_NOACCESS cannot be locked.
Locking pages into memory may degrade the performance of the system by reducing the available RAM and forcing the system to swap out other critical pages to the paging file. Each version of Windows has a limit on the maximum number of pages a process can lock. This limit is intentionally small to avoid severe performance degradation. Applications that need to lock larger numbers of pages must first call the SetProcessWorkingSetSize function to increase their minimum and maximum working set sizes. The maximum number of pages that a process can lock is equal to the number of pages in its minimum working set minus a small overhead.
Pages that a process has locked remain in physical memory until the process unlocks them or terminates.
To unlock a region of locked pages, use the VirtualUnlock function. Locked pages are automatically unlocked when the process terminates."
The SetProcessWorkingSetSize functions allows you to get more locked memory.
"The SetProcessWorkingSetSize function sets the minimum and maximum working set sizes for the specified process.
The working set of a process is the set of memory pages currently visible to the process in physical RAM memory. These pages are resident and available for an application to use without triggering a page fault. The size of the working set of a process is specified in bytes. The minimum and maximum working set sizes affect the virtual memory paging behavior of a process.
The working set of the specified process can be emptied by specifying the value -1 for both the minimum and maximum working set sizes.
If the values of either dwMinimumWorkingSetSize or dwMaximumWorkingSetSize are greater than the process' current working set sizes, the specified process must have the SE_INC_BASE_PRIORITY_NAME privilege. Users in the Administrators and Power Users groups generally have this privilege. For more information about security privileges, see Privileges.
The operating system allocates working set sizes on a first-come, first-served basis. For example, if an application successfully sets 40 megabytes as its minimum working set size on a 64-megabyte system, and a second application requests a 40-megabyte working set size, the operating system denies the second application's request.
Using the SetProcessWorkingSetSize function to set an application's minimum and maximum working set sizes does not guarantee that the requested memory will be reserved, or that it will remain resident at all times. When the application is idle, or a low-memory situation causes a demand for memory, the operating system can reduce the application's working set. An application can use the VirtualLock function to lock ranges of the application's virtual address space in memory; however, that can potentially degrade the performance of the system.
When you increase the working set size of an application, you are taking away physical memory from the rest of the system. This can degrade the performance of other applications and the system as a whole. It can also lead to failures of operations that require physical memory to be present; for example, creating processes, threads, and kernel pool. Thus, you must use the SetProcessWorkingSetSize function carefully. You must always consider the performance of the whole system when you are designing an application."
But these functions will not be supported under Win98. I know from some other function which was stated to be not supported under Win98 were supported under Win98SE.
But thats the time to get an answer from NI personal with more insight into what NIDAQ and the lvdaq.dll does.

Permanent and temporary partition sizes execeeds maximum size allowed
I receceivd error 818
permanent and temporary partition sizes execeeds maximum size allowed on this platform
I'm currently using TimesTen 32 bit version running Solaris and I increased one of my data storage size
to
PermSize=1700
TempSize-350
which is around 2G.
The system has 16G of memory, and the shared memory is set to 0xF0000000 which is almost the max of 32 bit.
Does anyone know this error is a sytem limit (32bit), or it can be fixed by tuning the system paramter? The system limits section does not have any information on the partition size limit. Anyone has any idea?That's correct, the 1 GB limit is specific to 32-bit HP/UX. All other 32-bit Unix/Linux platforms have a maximum size limit of 2 GB and as Jim mentioned this limit is such that:
PermSize + TempSize + LogBufMB + ~20MB < 2 GB
If you need anything larger you need a 64-bit O/S and 64-bit TimesTen.

Hello,
I own a Macbook Pro 15" (late 2011) and I would like to upgrade the memory. I want to go with two 8gb sticks but if the motherboard only supports 8gb then I will have to stick with 8gb. Also, the ram that I have in currently, which is the 4gb that came with the mac, is 1333 Mz. Would I be able to upgrade to 1600 Mz on this laptop?Max is 16 GBs. Do not attempt to use memory with specs that differ from those required by your hardware.

VHD Size is Maximum Size Allowed Without Using All Space in OS
Hello - I have a Hyper-V VM whose maximum size allowed is 700GB. Currently, the VHD file size is 700GB yet the OS is only using ~400GB (300GB free). Shouldn't the VHD size be about 400GB instead of 700? Every other VM I have checked matches the size being
used in the OS.
As I was typing this I think I answered my own question. This VM has a fixed size and all of the other VMs we have are dynamic. I assume this is why? It is a SQL server so I guess it is fixed for better performance. I didn't set this up
Can I safely shrink the VHD down a little bit? When trying to get replicas of this VM, it keeps crashing the VM due to space limitations. It is on its own Cluster Disk but it only has a few GB free which is why I believe it is failing. How much free
disk space is needed where the VHD is located in order for replication to work?
This is our SQL server so I am a little cautious in what we do with it.
Thanks for your help,
MikeHi Mike ,
Based on my knowledge for vhd , when you delete a file then this file was not deleted on disk thoroughly , just give it a deleted tag (the "old space" was not recycled until there is no new space for writing).
I think you can not make it smaller via shrinking .
Maybe you can try to compress the vhd file ( "edit disk..." ), before you doing this please backup your VM first .
BTW , it is recommended to use fixed disk for SQL server .

Is there a default maximum memory allocation ?
Hi,
I would like to ask if there is a default maximum memory allocation in the virtual machine?
I know there are params for setting the initial und maximum size but I'm not sure if the vm will take as much memory as I have in my computer or not.
thanks
guenterHi guenter
Are you looking for the -Xmx parameter?
According to the below link, the default maximum is 64MB

What's the maximum memory ram for Macbook Pro?
Hello,
May I know what's the maximum memory ram capacity for Macbook Pro?
I am having Macbook Pro - 2.53GHz Intel Core 2 Duo
Thank you!
AlvinHate to resurrect a dead horse but....I was looking in the instructions for memory upgrades and the instructions specified that the computer will only recognize 3 gigs. Will that still be in effect if I upgrade to Snow Leopard when it becomes available? Or do I need to save my pennies for a Mac Pro? What I am getting at is: is the reason for the RAM cap due to software issues, 64 bit not being native, different version of leopard used on notebooks, or is it due to hardware issues.

Maximum Memory Size & Memory Size
Will a server's memory automatically increase from Memory Size to Maximum Memory Size as the VM requires it? Or is this only valid for adding memory to the Memory Size value manually?
keithrust wrote:

Or is this only valid for adding memory to the Memory Size value manually?No, there is no automatic increase in memory. The max memory size just specifies the maximum amount to which you can manually adjust the memory of a running VM. I've now taken to setting the max memory size to the total available memory on my Oracle VM Servers, with memory size set to something reasonable. This way, I can adjust right up to the limit of physical memory without rebooting. -

Turn maximum memory available/user in Solaris OS
As part of the operating system turning for weblogic performance, how to check and turn the maximum memory available for a user process for Sun Solaris 2.6?
Thanks in advance.It's clear that MathWorks have not updated their software to 64 bits: I'd like them to, (and I have asked them when they will!) but I am wondering if there are limitations that stop me from getting more than about half of the 32 bit memory space.

Increase memory allowed to a program?
Hi,
Is it possible to increase the amount of virtual memory allowed for a particular program? I am running a big analysis (on a macbook with MAC OS 10.4) and my program tells me that I need to increase my memory to perform the analysis?
thanks,
sebHi Seb,
Nope, it's all taken care of automatically in OSX, (unless you're speaking of a "Classic" OS9 APP), what it likely means is that your HD is running critically low on free space.
How much free space is on the HD, where has all the space gone?

Maximum connections allowed for AMS 5.0.1
How can I find out the maximum connection allowed for adobe media server 5.0.1 standard license?
...that would depend on your application.
For a one-way video-on-demand system that streams recorded video at the user's request. Adobe Media Server serves only one stream to each user.
Here are the bandwidth calculations you would make:
Calculating server bandwidth needs (BWs):
BWs = N × S
where N = number of simultaneous users (subscribers)
and S = average bitrate of encoded A/V content
For example to calculate the overall server bandwidth needed to stream video encoded at 500 Kbps to 1000 simultaneous users:
500 Mbps = 1000 × 500 Kbps
The above assumes that content is encoded at a constant bitrate. Most often, however, you will vary the bitrate of the content to suit the viewing audience. This affects your bandwidth needs at both the client and server level.
For example, suppose you estimated that half of the 1000 simultaneous users were going to connect via 350 Kbps DSL modem and the other half via 3 Mbps cable modem. Suppose further that while the video encoded at 500 Kbps was appropriate for the cable viewers, you wanted to encode a separate video at 150 Kbps for the DSL modem users.
In this case, the total bandwidth required of the system is lowered to 325 Mbps:
325 Mbps = (500 Kbps × 500) + (150 Kbps × 500)
This help ?
