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.

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?

I have 16 GB physical memory and my kernel_task file grows to use all my available memory. How do I fix it? It is now completely utilized and Kernal_task is 9.3GB.

MY computer is acting strangly and now my physical memory of 16GB is completely utilized all the time. I noticed that the kernal_task is now 9.3GB and I don't know why. If I restart the system I am only using about 6GB and then it starts to use more until it is completely utilizing everything WHY?

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.

How to make use of the spare physical memory under buffered I/O of Essbase

We encountered an issue of the physical memory allocation of the server running Essbase with buffered I/O mode. We have implemented some cache setting in Essbase but still found that the disk I/O is quite high. Also we observed that Windows 2003 server cannot make use of the spare physical memory available as the system cache for database files of Essbase.
As allocating more memory as Essbase cache might not help, we would like to know other than changing to direct I/O mode, any other options can improve the disk I/O performance?
Thanks!

Hi Hyperion_User,
1. Disk IO performance,It mighe depend on quite a few things , one of the aspects might be your storage system. It can depend on the disk configuration too ( i.e if your disk is SAN or NAS, then it depends on the configuration like Raid ..etc).
2. It depends on the HBA ( host bus adapter).
3. Let me try to explain with diagram.

4. It might depend on the HBA and even on the switch speed.
5. Buffered IO is a very generic setting,which most of them use( that should not be an issue).
6. Even if you have 30 to 40 GB free memory, every application in essbase has a limitation to it maximum usage ( 2 GB on windows ). Refer to DBAG for more information on this .

Thanks for your detailed advice. I just wonder if more physical memory can help to improve the disk I/O being used for concurrent read/write access. We are using Windows 2003 Enterprise Edition and not sure whether some spare physical memory can be used for this purpose.
Thanks again!

Early 2008 MacBook Pro RAM upgrade limited to 3GB??

My brother in law has an early 2008 MBP, 2.4GHz, I'm pretty much sure we are talking about the one described in this Apple tech specs:
http://support.apple.com/kb/SP4
Now, it says that it supports up to 4GB of 667MHz DDR2 SDRAM. He bought 2x2GB Kingston memory modules , but the shop sold him the 800Mhz ones. Still they do fit and if only one is present together with the old 1GB 667MHz one it works fine reporting a total of 3GB. With the 2x2GB together the MBP doesn't even start.
My understanding was that such a MBP could support up to 8GB of RAM with the new 4GB memory modules (well probably with SL at 64 bits, which works). Personally I have an early 2007 MacBook and I know there is a 3GB limit due to the GMA 950 (video chip) reserving higher addresses.
Is there a similar situation for the MBP? I thought the memory speed being higher shouldn't matter (and it works indeed with one 800MHz module). Or is that MBP really limited to 3GB maximum? Any idea?
Message was edited by: Michelasso

yes, he will bring everything here today. I think he didn't buy the KTA MB800 anyway (made for Apple by kingston). Just generic. They are too cheap. But I have to check. Reading around I've found out that only the Penryn MBP should have the problem with faster RAM. Here is a good guide:
http://forums.macnn.com/69/mac-notebooks/358184/a-guide-to-macbook-ram-upgrades/
Well, he's still on time to give the RAM back and get the refund. Thanks for your help anyway.

Reduce Physical Memory Amount on Windows 2003

Hi all,
I need more information about reducing physical memory amount on windows 2003 64bit.
I have Front End Exchange Server 2003 with 48 Gb Physical Memory, and i want to reduce physical memory to 16Gb. Is there any impact to exisiting OS or Exchange Server?
Regards,
Rengga Patria

Hi Rengga,
For the impact to the whole operating system, it depends on the server’s workload.
As to the impact to the function of the Exchange Server role, as far as I know, 4 GB of random access memory (RAM) is the maximum amount of memory that an Exchange Server
computer can efficiently use.
Regarding physical memory and Exchange server 2003, the following articles can be referred to for more information.

http://blogs.technet.com/b/exchange/archive/2005/07/05/407330.aspx
In addition, for this is concerning Exchange Server role, in order to get better advice, we can ask for suggestions in the following Microsoft TechNet Exchange Server Forum.

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.

Physical memory and paging

I know in SAP's world, memory means physical memory + paging. I want to know which program has contribution for swap.
Suppose there is 4G physical memory on an application server, em/initial_size_MB = 4G, abap/heap_area_nondia = 4G.
1) If there is no dialog processor running and one background job running which claims 2G memory, I want to know will swap occur?
2) If there is one dialog processor running which claims 2G memory and one background job running which claims 2G memory, will swap occur?

By ST03N you can check the workload, by OS06 the swap .
By transaction ST02 you can check the folllowing parameters:
SAP Roll area parameters
- ztta/roll_first          : First amount of roll area used in a dialog WP
- ztta/roll_area             : size of the local SAP Roll area in the work process
rdisp/ROLL_SHM      : size of SAP roll Buffer
rdisp/ROLL_MAXFS     : size of entire shared SAP roll area
SAP Extended Memory main parameters :
em/initial_size_MB : size of SAP extended memory allocated when                         the SAP instance starts up
em/blocksize_KB : size block which split SAP Extended Memory
ztta/roll_extension : maximum size of a user context in the SAP Extended memory
SAP Heap Memory main parameters :
abap/heap_area_dia       : quotas oh SAP heap memory that a dialog                                 process can allocated.
abap/heap_area_nondia : quotas oh SAP heap memory that a nondialog                    process can allocated.
abap/heap_area_total     : size that can be allocated in total by all work                    process.
abap/heaplimit           : Workprocess restart limit of heap memory
if helpful reward point is appreciated

Physical Memory Upgrade [SAP, Oracle parameter changes]

Hello Guru,
Good day!
I'm not sure if I'm in the correct forum, please bare with me if I'm not.
We are actually planning to increase our Production [Physical Memory] server from its current size 15360GB including [oracle, SAP & OS] to 44GB memory.

I feel the best way to get the parameters which needs to be adjusted is to go for EarlyWatch Check after increasing the Physical Memory of your SAP system, as we cannot say how and which parameters needs to be checked and changed.. as there is some dependiblity also between the parameters...
All the best !

IPOD causes "Blue Screen of Death" with physical memory dump

Plugged in the IPOD into USB port on computer. It shows "found USB device" and then 5-10 seconds later I get the blue screen of death and a notification that there is a driver error and a physical memory dump as occurred.
Spent two hours with Apple people and Dell people this morning and nothing. I have updated drivers, flashed my bios, uninstalled and then reinstalled the latest version of Itunes.
Any help would be greatly appreciated.

what numerical and text codes are you getting with it? (ie 0x[zeros/letters/numbers] CAPSANDUNDERSCORES)
if the blue screen mentions a specific file, let us know what that is called too. (exact spelling, please.)
here's a reference on the sorts of things i'm asking about:
Troubleshooting Windows Stop Messages
if you're just seeing a flash of a blue screen, we can use this technique to make hidden blue screens appear for us:
1) Open your system control panel (Start->Control Panels->System).
2) Select the "Advanced" tab.
3) Click the "Startup and Recover" section's "Settings" button
4) Verify that under "System Failure" the "Automatically restart" checkbox is not checked.

Physical memory cache behavior in Windows Server 2008 Enterprise

I have a question regarding how windows manages the cache portion of phyiscal memory. I have 2 servers which are identical OS configurations, hardware and experience nearly identical workloads. Server 1 appears to use its cache a lot. I often
see physical cache at at 75% of total memory (total is 16gb for both servers). I also see that the cache stays this high
even when overall memory utilization is minimal (say approx. 3-4gb out of 16gb for long durations). I suppose this means windows memory manager is keeping pages in the cache because it anticipates it may need them again, but would overwrite them with
new data if new processes needed it (I think of this cached memory when the system is near idle as "available" but correct me if I am wrong?)
Server 2 (again same workload and identical hardware, OS, configuration) doesn't appear to use cache as much. In fact, cache is always low round the clock (2 gbs usually) even when there is little to no memory utilization from processes outside the OS. Basically,
it is low when the server is near idle, while the server 2 keeps it very high during the same period of minimal workload. Why the difference? Does this behavior sound normal? Please advise. I am not a Windows Admin btw. I have a rudimentary understanding
of memory.. or so I believe at least : )
Thanks.

Hi,
Although both server are identical OS configurations, hardware and experience nearly identical workloads, there are still differences between them. We can use task manager on both server and Check which processes are using physical memory, please go through

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.

How to get the amount of free physical memory?

How to get the amount of free physical memory?
(without sudo or root)

vmstat will give it to you.
Although the question depends a bit on what you mean by free memory.
The figure vmstat labels free (in any reasonably recent version of solaris) actually represents memory mostly filled with cached file contents. So it represents memory that can be easily released if needed by something more important.
Like most unix versions, solaris will use any free memory to cache files thats have been read/written previously just in case they are needed again

HP Pavilion dv6 Vista Recovery - Physical memory dump w/ error code 0x000000F4 (and others)

Hello Everyone,
This is my first time posting in the forums so I hope that I have chosen the appropriate area and will do my best to be brief but informative.
Computer: HP Pavilion dv6000
Operating System: Windows Vista.
For the past 6-8 months it has been unable to perform Windows Update citing that the most likely reason was a virus. I have tried numerous trouble shooting options when it was recommended that I perform a chkdsk. After initiating a chkdsk in Command Prompt, my computer restarted and had a black screen with no cursor. After watching this for 2 hours and realizing that none of the usual chkdsk progress or text was coming up I made the decision to force shut down.
When I rebooted, I was told to enter system recovery which I did and completed a system recovery from the hard drive. After the system recovery finished and the laptop restarted, I experience a Blue Screen of Death due to a physical memory dump. The error codes are STOP: 0x000000F4 (0x0000000000000003, 0xFFFFFA8006671040, 0xFFFFFA8006671278, 0xFFFFF80001D01DA0).
I am not able to boot in safe mode. In the start up repair, I am able to enter command prompt from which I started chkdsk again. Both chkdsk f/ and chkdsk r/ passed with no errors. Additionally, the computer passed both UEFI Hard Drive and Memory tests. I have system recovery CDs for the computer but they fail at 78% completion.
Please let me know if you have any questions or require anymore information. I would appreciate any and all advice!
Thank you!
