P52s Usable Memory

Q: P52s Usable Memory

Have just bought a ThinkPad P52s Have setup a multiboot with Windows 10 (64-bit), Windows 7 (64-bit) and Windows 7 (32-bit) and have 3 issues: (2 of 3 ): Usable Memory on Windows 7 (32-bit) is 1.4 GBytes The Laptop has 16 GBytes Ram and the usable Memory on Windows 10 and Windows 7 (64-bit) is about 15 Gbytes. However on the Windows 7 (32-bit) this is 1.5 Gbytes. (I know that 32-bit system can only address upto 4 Gbytes)The system has reserved about 14 GBytes. What can I do to increase the usable memory by a GByte or so. Thanks

Preferred Solution: P52s Usable Memory

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Hey guys,does someone knows if there is compatibility list for memory from lenovo for the p52s? I couldnt find any infos on the website.Thank you 

A:memory compatiblity p52s

The safest is to buy Lenovo-branded or memory with Lenovo FRU.  After that, just avoid sticks with the word "value" in the name.

I recently did a new install of Windows 7 64 bit. I noticed windows showed 4Gb of ram (2.75Gb usable). I read tons of articles after googling this and tried several options to free up some more ram.

I have 2 options in bios to change memory remapping over 4GB. S/W and H/W.

When I enable S/W remapping, windows boots everything seems fine but I get a crackling sound from speakers. Bios shows 4Gb (3Gb usable). Windows shows 4Gb ram (3.0 available).

When I enable H/W remapping, windows BSOD during boot, but bios shows 4Gb ram and all 4 Gb available.

So, does anyone have any suggestions as to how to eliminate the BSOD after enabling H/W memory remapping? Try installing Windows 7 again? I read some people saying bump up the voltage on ram perhaps? I've never done any overclocking, but would try if someone thinks it may help.

I've tried several different setting. Any help would be greatly appreciated.

A:4Gb memory (2.75 Gb usable) memory remapping in bios causes BSOD

This sounds almost like a bios memory compatibility issue to me.
Have you tried checking the ram in both modes using memtest?
RAM - Test with Memtest86+
Since the memory is obviously the center of this I think it bares testing.
Keep in mind you'll need several passes each way with memtest to get any kind of accurate result and will take some time

Configuration: 1x Intel Optane Memory Module - 32GB M.2 2280 80m1x M.2 42mm to M.2 extension adapter Problem: Tried installing memory module in P52s chassis, chassis only supports up to 42mm M.2 add-in cards. Purchased aftermarket 42mm to ribbon cable extension adapter to fit the module into the chassis. Attempted to install Intel Optane Memory driver from Lenovo, the Intel Rapid Storage technology application did not report the prescence of the Optane module after the fact. Uninstalled Lenovo provided software, installed Optane software directly from Intel, Intel installer noted that my BIOS does not support Intel Optane Memory. Question: Will Lenovo continue to update the BIOS and will I forseeably have support for the module at some point in the future? What would be the avenue to escalate this issue if it is not currently on their roadmap?

i have a new HP Z400 workstation. it has a new install of windows 7 enterprise 64bit with all updates. the pc came with 6gb of ram installed. i purchased 6gb of kingston memory that was specifically listed for this workstation. the ram is installed as 6 x 2gb modules. slot 1 factory module slot 2 kingston module slot 3 factory module slot 4 kingston module slot 5 factory module slot 6 kingston module. when this pc just had the factory modules it shows 6 gb installed 5.83 usable. it now shows 12gb installed with only 3.23 usable. what is causing the decrease in usable memory as well as what is causing the usable memory to be a fraction of the installed memory?

A:adding memory results in less usable memory

First reseat the ram sticks.
I would change locations of the sticks too
If still have the problem, take Ram Test
Download memtest86 and test RAM
Run for 6 passes/

Just as the topic looks, that's what I'm having an issue about right now. Now, lets begin by laying some different things out on the line. 1) I used search, 2) I used Google, 3) I even tested this on different machines (will explain below), and 4) I put this in the right forum... I hope..

Ok, I work in an office and I got an agent to come to me to help them install Java. Knowing he ran Windows 7 - Home Premium, I checked the System menu for what version OS he was running. I noticed 64bit, but couldn't help to notice that he had 3GB installed (2.75 being used)... Right away this through up a red flag because I thought that Home Premium 64bit was able to fully use every bit of installed memory up to 16GB. Acer is the manufacturer of the laptop, so I don't know if they might have something messed up in the BIOS or if it is simply because he got it about a week after Windows 7 was released.

The reason that I am fearing this is because I have a custom built desktop that is currently running 4GB (3.25 usable) of the Windows 7 RC Ultimate 32bit, so I know that I'm only going to get about that much out of my RAM. However; because it is soon time to reformat, I have a Windows 7 Home Premium 64bit CD + Key waiting to be used, and another 4GB of memory to be installed. I don't want to have an issue when reinstalling that I'm going to be missing any bit of RAM being used either just because I'm using Home Premium or any other reason.

A:Installed Memory (Usable Memory)

Hello Joshgt2, and welcome to the forums

Theoretically 64bit can address 128GB of RAm , although Motherboards typically do not support such amounts yet.

Certain chipsets (Such as AMD) using built in graphics, will use a certain amount of RAM dedicated to graphics only.
(naturally it pulls this dedicated graphics memory from you installed RAM)

So if it is set dedicate say, 512Mb in the bios, and you have 4GB of RAM installed...

In Windows you would see something like 4Gb installed (3.5 useable)

By the same token, if you have 8GB installed, it would show 8GB installed (7.5 useable)

If you install a actual graphics card, and disable the onboard, you will gain full use of your RAM again, As a graphics card has its very own memory onboard.

hope this answers your question

A:Installed/usable RAM memory?

Hi starterz and welcome to Se7en Forums

That looks about right. On 32-bit systems, the total amount of memory that can be addressed is 4GB. Within that address range, there are also the system I/O devices and other hardware. These in effect take up some of the available memory space, so the amount of physical memory available to your system actually reduces by that amount. Depending on your system's hardware and configuration, this can be anything ranging from 256MB to 1GB (typically 768MB). However, that can vary. In addition, on a laptop the GPU is allocated a portion of your RAM for its own use.

This is from my system. What does yours show for the Graphics section?

You didn't describe the motherboard in your computer, so it's possible that a setting change needs to be done in the BIOS, or a BIOS update needs to be done.

I used to have Vista (32-bit) on the machine, 4 GB RAM installed on the motherboard. Vista was able to allocate around 3.00 GB for itself, with a videocard that had 256 megs of RAM on it.

As my old video card busted, I changed it into Club3D's Geforce GTS 250 with 1 GB of memory, and naturally didn't take a look how much Vista had "available memory" after that. Got the Windows 7 update on Vista, and now I'm seeing in the system :

Memory : 4,00 GB (2,00 GB usable)

I took a look at Task Manager, and it also shows 2048 MB as available memory. Looking at the videocard's specs, I can see that it has 1024 MB of dedicated video memory, and shared system memory 767 MB.

Knowing that the maximum memory 32-bit Win is able to map is 4 GB, still the math doesn't seem to work for me. 2 GB for OS + 1 GB for the video adapter makes a total of 3 GB. If the shared memory isn't in the 2 GB Windows 7 shows as available, then we'd have 2 GB + 1 GB + 0,7 GB = 3,7 GB which starts to sound more reasonable.

For fact, I know that I have memory re-mapping on in BIOS, and BIOS check says 4096 MB of memory installed. The motherboard in question is ASUS P5B. Should I somehow be able to get Windows to use 3 GB of the 4 GBs installed, or is the latter math part right, and the system is already using all that it can?

First of all, the problem is this
I have a Custom-built Desktop PC with the following specs.

RAM 4.00 GB (3.00 GB usable)
Graphic card: Nvidea Geforce 9400 GT.

So, the problem is as you can see, I have recently installed 4 GB Ram in my computer, When  I open my BIOS it detects both the RAM sticks-i.e- 2GB, 2GB each (they are a model of HP) (the RAMs are DDR2). But when I start my windows 7 and open the system
properties, it says that only 3.00 GB is usable. And the problem for this is certainly not a bad RAM because 3 GBis usable so 1 GB of the supposedly bad RAM stick is usable.
However, I found the problem when I open my "Resource Monitor", where in the memory tab it says that 1096 MB is "Hardware Reserved". This is too much as many other computers have only 2 mb or near to it "Hardware Reserved". I really
need to solve it. Here are some points.

-Actually my mother board manual says that only 2 GB is supported but I heard that that limit isn't necessary to follow, and 3 GB is usable so it is already exceeding the limit.
-I have windows 7 32-bit, which has a limit of 4GB and since I am not exceeding that , then that should not be the problem.

Hi there,
I just bought a new 4.gb corsair DDR 3 memory card for my pc recently, and after installing it, it comes up saying it has 6gb of memory installed (2gb usable).
That is from the system tool in control panel.

Of course task manager confirms in the performance tab, that there is only 2gb available still.

I have double checked the motherboard specs for compatibility, and it has the DDR 3 cards on the support list, so I don't get why it's coming up as unusable...

The board is gigabyte gap55ud3
Running windows 7 ultimate 64-bit
I7 core Intel

What can I do to get this memory card working?
Could the board maybe only have a couple of slots that work in the frequency range of my card? (1333mhz)
OK, so after a bit of trouble shooting, I noticed a couple of things:
Firstly, the first memory slot (first on the left) on my motherboard is dead (due to the shop mounting my motherboard incorrectly, and shorting it out), so I had the 2gb card in the second slot, and had the 4gb card installed on the 3rd slot.
I took out the 2gb card, and replaced it with the new 4gb card, and it runs fine.

However, this still doesn't answer for the fact that it picks up the memory as unusable, if I install the card on the 3rd slot.
Could my guess earlier have been correct?
Could it be that only 2 of the slots are compatible with the higher frequency cards (1333), and the other slots only work with lower frequency cards?

A:6gb memory installed, but only 2gb usable???

Check the motherboard User Manual. When mixing and matching memory cards, there are sometimes specific slots for them to be installed into. And sometimes you cannot mix different sized cards. Again, it should all be covered in the User Manual.

In any case, installation wouldn't appear to be an issue. As you have already noted several times, the motherboard and OS are recognizing 6GB. Which would lead me to believe it's an OS related issue.

Old Dimension 5000, running Windows 10 Pro 64-bit better than it ever did any previous Windows version, quite surprisingly.
What I've always wondered and never fully understood is why usable RAM is less than the physically installed.  I know this mobo and chipset is limited to 4Gb, which is installed in the form of 2x2Gb.  Both memory sticks are tested and come back 100% ok, and Windows does recognize 4Gb, but reports only 3Gb of it "usable".
Interestingly, when I played with different new video cards for an upgrade, the usable memory varied between 2.25 and 3.25 Gb depending on the card.  The card I ended up keeping since it worked best in this old system leaves Windows with 3Gb usable RAM.  This would indicate to me this issue is also rooted in the mobo and chipset, and maybe limited options of the rather archaic BIOS.
I've been using 64-bit versions of Windows 7, 8, and 10 on this machine, and showing the same amount of usable RAM with the video card I used at the time, so I'm assuming they're all behaving the same here.
Any insights beyond my assumption that this issue lies in the hardware/architecture?  Any remedies maybe?  I know I have the latest BIOS v07.

A:usable memory problem

I see you have 32-bit (x86) Windows 7. 32-bit Windows cannot use a full 4GB of RAM. A lot of people report only having 3GB usable, so you are actually getting a little more than many. The only way to be able to use the full 4GB is to use 64-bit (x64) Windows, but if RAM is your only concern, you won't see much difference.

Hi there,

I have just added 4Gb Crucial memory (2x2Gb) to my existing 2Gb RAM (2 x 1Gb) for 6 Gb total. The system info shows 6Gb but only 4.94Gb usable.

Any suggestions as to the difference and how I might get more usable memory?

n.b. When only 2 Gb was installed it all appeared usable.

(I have looked and Max Memory is unchecked in msconfig)

A:Memory upgrade not all usable

I know that crucial tells you what you should use, but the first rule is dont mix and match, nothing but trouble
Second take a memory test to see if its the slots or the sticks or neither

To the future posters, lets not get into the mix and match thing. If thats not the problem, here fine, lets just find out what is the problem.

VGA Memory heatsinks, re-usable?


I'm helping someone transfer their VGA Zalman fan on a dead video card to a new one, but are the Heatsinks re-usable? Especially since the thermal tape probably wouldn't stick anymore if removable at all.

Or should this person just throw in cash for new ones?

A:VGA Memory headsinks, re-usable?

remove and get new thermal tape. Simple solution

Question is just where to get new ones.

I have looked in several forums, including this one. and every option i have found. dont help me so much ;(

I have also checked the BIOS . but there is no place where i can dissble " Dram over 4Remapp" or something like that.

everything i can think of i have checked.

I know 32bit can't handle more than 2 or 3GB memory, but it can handle 2gb, that much i know.
when i start my computer. it show 1024mb ram . that counts that up. but in everything else it shows 2GB bit 1 usable.
and it says that 1024mb is hardware reserved, ( maybe it is that ? how do i change that ?
I have run a test. nothing wrong with either of the memory sticks
I also have seperat graphic card with 512BM Ram on

can someone help me , please.

Thank you

Errrr I think you mean you have 2gb but it will only use 1. Is the slot for the RAM card working? Also is the Ram chip still working, a pin might not be working

HiI have a problem with the usable RAM memory of the Acer Aspire V5. The machine cames with 4GB of RAM but only 1.44Gb is usable, which is very low and make the system unusuable when trying different applications.This problem started since I had to replace a damaged HDD and I reinstalled Windows 10 from an USB Stick. (The same problem shows up on Windows 7 32/64bits)Full Model: Acer Aspire V5-122P-0642Windows: Vesion 10 64bits.Full RAM: 4GB.I tried:1) In Windows 7 and Windows 10 the MS tips about it. "msconfig- Boot tab -   Advanced options and uncheck "clear the Maximum memory check box". It didn't work.https://support.microsoft.com/en-us/kb/9786102) The BIOS doe snot has any options on about " AGP video aperture size" or "Memory Remapping". I was not able to find anything like that (help is welcome) 3) The BIOS of the machine is updated to the latest: 2.12 - 2014/07/24Please, any help or idea is welcome. I don't remember what was the amount of memory usable before (with the older crashed HDD) since I didn't have that lacking memory problems.Regards

I'm sorry to post again about this problem but it drives me mad!
I just can't get my memory to work.
Got 8 x 2GB sticks and when all installed the Buzz of death goes off and that's it.
If only installed in slots 1 and 2 everything's OK.
If in 1, 2, 3 and 4 ... Buzz of death.
If in 1 and 2 and 7 and 8 as in image below, 8GB installed 4 GB Usable
Please can you help?

So that's that.
My operating system is 64-bit windows 7
i put up a txt that has all the info of my machine i thought might be remotely relevant taken from "cpu-z" program.
I took the picture of my discomfort (from panel control>System)
And i also took a picture of task manager>performance while pushing my system a little more than ive ever done so.. showing under "commit (MB)" over 2000.
The bios says that the 3gb are both installed and usable

I suppose that as stated in another post i found elsewhere the system is actually using the 3gb tho not really showing it. (considering that i pushed it far enough that it would have crashed if it only had 1).

I want it to show that it has the 3gb usable.

Anybody that suggests memory diagnostic without a more complete set of suggestions dont bother posting -.-

A:Solved: 3gb installed memory (1gb usable)

Hit your windows key or the start button, type 'windows configuration' and then press enter.

Select the Boot tab then select advanced options. Make sure that you do not have the 'Maximum memory' box checked.

Also check and see if the BIOS on your motherboard has the ability to do memory remapping. If so, for your 64bit OS, turn it on.

Hi, hope everyone had a great Holiday
I have windows 7 home premium 64 bit, 6 GB and so does the os, but why is it only allowing me to use 2.96gb. How do I get the pc to read the full 6 GB ?
In the task manager and the sytem properies it reads : Installed memory (RAM): 6.00 GB (2.96 GB usable) . Is this correct? Is is allright to have more Ram avail. for me ( How do I do this?????) or is this the way that it's meant to be and I need to simply buy more RAM If I want more?
Thanks in advance for any and all help.

A:Installed memory (RAM): 6.00 GB (2.96 GB usable) . Is this correct?

You should have about 5.2 GB available. Some of the 6 GB is used for your Video Card. Right click on Computer and Left Click on Properties. Use your Snipping Tool to give us a Screen Shot. Thanks,

Hey guys, so today I received my My 1GB Kingston memory module;
which I thoroughly checked that it was compatible for my laptop before purchase,
My Laptop has two memory module slots.

The previous RAM setup I had was 512MB + 256MB = 768 (759 Usable)
After implementation of the 1GB RAM = 512MB + 1GB = 1.50GB (768 Usable)

These were/are from on my system properties info.

IS the 1GB memory Module defected?
OR is should I have nothing to worry about?
Additional info:
Toshiba Satellite Pro U200 (Notebook)
OP: Windows 7 Home Premium 32bit
Processor: Genuine Intel(R) CPU T1300 @ 1.66GHz
Graphics Card: Mobile Intel(R) 945 Express Chipset Family

Plus the Motherboard can handle upto 4GB of memory installed; (2GB for each slot).

You guys reckon swaping the memory modules around would help?
Since the 512MB module was the main one from the start...

I have Windows 8.1 32-bit installed and have fitted my PC (Dell Inspiron 531) with 4GB RAM.

The system only reports 3.25gb as usable - where has the remainder gone?

Is it the Graphics card (ATI Radeon HD 2600 XT)?

I understand that Win8.1 32-bit can utilise a full 4GB of RAM?

Also in the Task Manager, it reports that I have used "2 of 2 slots", however I have 4 RAM slots inside the machine where the RAM is fitted (4 x 1GB fitted).

Any help?
