MSI 870S-G46 8GB Ram Installed/Detected 4GB Usable W7U-x64

Hey folks,
So I have a rather iritating issue. I just upgraded to a MSI 870S-G46 and I have been having issues with my ram. I have 2 4GB DDR3 "1600mhz" sticks made by Kingston.
I AM running Windows 7 x64, infact I have done a clean install periodically through testing on my secondary drive. Same results. A pic just to make the point. (Alt+printscreen ftw!)
The bios has been updated to latest. Via usb. Set to optimum and poked with too. (Don't see any force remap switch... so I assume this board is supposed to always do remapping...)
I have tried both reseating(XD Been seated a good 4 times now in all for an identical result)...
AND another cpu(even reseated said other cpu once). No change.
Even tried with the stock heatsink that isn't as firm on as mine clamps down.
... And a fresh install several times throughout this process on aforementioned secondary drive.
Both ram sticks are good, have tried both individually in slot 1, and both combinations of slot 1 and 2. (This board has slot 1/2 and 3/4 paired with same color.)
@.@... ... ... Elp?

this recently happened to me, i updated my bios because i kept getting IRQL errors. the errors have stopped but now i have only 4gb usable from 8gb. (g.skill 1600 ram) slot 1 and slot 2.
when i put in slot 1 and slot 4 it read all 8gb but its very unstable. the IRQL happens 5 minutes in and boot takes a long time (other BSOD too). i tried lowering the speed but still no good.
im on bios version h.C0, updated thru live update.

Installed memory 4GB (932MB Usable )

i cannot fix this proble.
please reply fast.
i can't download cpu-z from geven link.

Hi,
There was a fix implemented in Bios version F.25 for your notebook series that corrected an issue with machines not using the full memory capacity when running a 32bit OS in conjunction with greater than 2Gb of ram being installed.
As HP Bios Updates are cumulative, you're probably better off just installing the latest version ( F.26 ) which can be downloaded from the link below. Although not noted on the page, the cva file lists this update as compatible with the following operating systems.
W732EN=OEM
W764EN=OEM
W732HB=OEM
W764HB=OEM
W732HP=OEM
W764HP=OEM
W732PR=OEM

Note: Once started, do not interrupt the bios update in any way until it has completed - the machine may perform several restarts and may appear to be doing nothing for short periods of time, but just let it complete until it has loaded back into Windows.

Nothing wrong with that. According to the spec, you should have 1 GB of memory.

Added memory to 4gb but 2gb is "inactive"?

I changed the memory in my 2008 24 inch IMac because I had very little "free memory" according to activity monitor. Now I have 4gb but 2gb always is inactive and I still very little free memory therefore the computer still is dragging.

From the help topic "Viewing system memory usage" for Activity Monitor:
Inactive memory contains information that is not actively being used. Leaving this information in RAM is to your advantage if you (or a client of your computer) come back to it later.
IOW, it is normal to have a lot of inactive memory. If your computer is slow, there may be some other reason for that, or it may be that you have a lot of applications open at once.

I'm need upgrade my memory ram but.... Wath diference for 4GB (two 2GB) of 1600MHz DDR3 memory and 1600hz ?

I'm need upgrade my ram 4GB (two 2GB) of 1600MHz DDR3 memory to 16GB (two 8GB) of 1600MHz DDR3 memory but wath diference in 10600hz to 1600hz

There is a big difference between 10600hz and 1600hz
The 2012 Mini needss:

Slower memory will not work in a Mini that requires higher speed memory.
Sometimes faster memory will not work in a Mini that requires a slower speed.

I would like to upgrade my OS to the latest version. I now have 10.6.8 and my machine has 1Gb of memory. Need 2Gb for the new OS. Is is possible (and practical) to add memory to a machine that's five years old?

You can put two 2gb RAM sticks in your model 2,1 but it can only use 3,3gb. This is a hardware limitation and cannot be changed.
http://en.wikipedia.org/wiki/3_GB_barrier
http://www.everymac.com/systems/apple/macbook_pro/faq/macbook-pro-core-2-duo-3-g b-memory-limitation-details.html
OWC tests have found that there is a slight speed increase with having two 2gb sticks in rather than one 1gb and one 2gb. Your model is in the gray lines at the bottom of the graph. http://eshop.macsales.com/shop/Memory_Benchmark/Apple_MacBook/
You can buy Lion for $29 from the App Store witht a model 2,1 MacBook. Lion will require at least 2gb of RAM but really needs 4gb to run smoothly. As for programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table
Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.
These are good online stores for Mac compatible RAM
OWC http://eshop.macsales.com/shop/memory/MacBook/DDR2/ - They offer Mac tested RAM at very good prices.
Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model
Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.

Recently upgraded memory, not usable

Hi, I have a HP Probook 6555b laptop which came with 4GB installed RAM. O/s is Windows 7 Professional 64bit. The specs says that the max memory that can be installed is 8GB.
I have upgraded the RAM to 8GB, 2x4G DDR3 SODIMMs.
When I go to system properties, it shows the installed memory as 8GB, but usable memory as on 2.74GB.
When I go to task manager, performance, resource monitor, it shows 5.3GB as reserved for hardware.
I googled a bit and a few people mentioned that I have remap the memory in the BIOS. The BIOS also shows the installed memory as 2x4B, but unfortunately the BIOS has no option to remap the memory. The BIOS is up to date.
Can anybody please help?
Thanks a lot.
This question was solved.
View Solution.

Ok, found the solution.
Nothing to do to with BIOS remapping, etc.
Opened 'msconfig', went to 'boot' tab, clicked 'advanced options', and unticked 'maximum memory'. After the restart, it now shows usable memory as 7.74GB.

How do I add more memory to my Imac, I only have 1GB of memory and need 2GB to download Yosemite!

How do I add more memory to my Imac, I only have 1GB of memory and need 2GB to download Yosemite?

Janet,
This is why the question rkaufmann87 asked about your model is so important:
[click chart to enlarge if needed]
The list covers the early iMacs with Intel processors that shipped with either OS 10.4 or 10.5 and have only two RAM slots. As you can see, some have limits to what version of OSX you can install. If the step rkaufmann requests does not narrow down your model, you can do one more thing.
While the "About this Mac" window is open, click the "More Info..." button at the bottom of that window to get this (assuming you are really running OS 10.5.8 as shown in your profile):
The code I've indicated with the red arrow corresponds to the codes in the second column on the chart. Post the code your computer reports--again don't post a serial number.
If your iMac shipped with only 1GB RAM, I fear it is one of the earliest models that cannot be upgraded all the way to Yosemite.

On each machine turn on iCloud and sync all the available apps. Apple explains how to set up iCloud in http://www.apple.com/icloud/setup/
After doing this run software update on each machine and install all the suggested updates. If you still need help installing the most up-to-date versions of iLife and iWorks open the Mac App Store - click the Purchased tab and update all that need to be updated.

NF520T-C35 compatible with GTX460 video cards?

Hello,
to cut it short - I have problems installing Msi Cyclone GTX460 768MB/OC on this mobo. Until now I had Asus 9800GT which worked flawlesly. Preparation is done as usual (cleaning old drivers), vga in case, login to windows (XP Home, SP3), installation of new drivers (from MSI DVD that came with vga), restart... Then I came to the Windows logo screen, keyboard initialized but mouse NOT, and then after a few seconds - black screen. Fans are working, nothing I can do except for restart.
After that I can boot to the safe mode, mouse will sometimes initialize, sometimes not, but I can at least logon to safe mode via keyboard. I did other varants that came to my mind:
-deleting drivers in safe mode, rebooting, normal logon in Windows, then installing the newer ones from Nvidia site. After the reboot, exact the same hanging after Welcome screen.
-deleting drivers in safe mode, reboot to normal Windows, installing the older drivers (last ones from 9800GT) - no help, because drivers do not recognize 460GTX, and ask for a newer drivers
The usual suspect in this case is a power supply (Cooler Master 450W Real Power, 12A/10A at 2x 12V rails in continuity, 18A/16A at peak 60. sec), but I doubt that it is a problem - even if the supply is not strong enough for excessive 3D, it can at least have enough power to boot into Windows?
So, the only other explanation that came to my mind is that maybe my mobo is not compatible with GTX460 card? Why, because I found reports that some people needed to update mobo bios for GTX460 to work, but without any specific details about manyfactuter, chipset, etc. The latest bios is installed on my mobo, from May 2010.
Any help will be highly appreciated!

So I gave up on waiting for a miracle to happen, and bought a new motherboard (Gigabyte GA-M720-US3). Straight instalation, not a single problem, vga is fast as Usein Bolt... All the other components in rig are exactly the same, as well as Windows XP instalation (no, I did not reinstalled it), so it is pretty clear that for some reason MSI NF520T-C35 motherboard is not compatible with GTX460 cards. Is it a problem with this specific mobo or with a design of GTX4XX series, it is hard to tell - I have found many reports that people are having identical problem (hanging at a Welcome Screen) with GTX4XX cards from other manufacturers, on many different motherboards, in all MS OS's. But for the end user, conclusion is clear...
Big thanks to all the people who tried to help me! Problem not solved, rather overcomed.

My start up disk Macintosh HD is full on my McAir OSX 10.9.4 memory 4GB. I need to clear the disk so that I can update it with the new software IOS 10.9.5 requiring 2.05GB. Need guidance on how to clear space.

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

How do I install memory into the Pavilion 17z-F2 series laptops?

How do I install memory into the Pavilion 17z-F (17z-F200, product L2H13AV) series laptops?
HP appears to have no maintenance guide available for this model series. What's up with that?
Please, do not offer the generic (and out-of-date) Pavilion 17 Notebook PC Maintenance and Service Guide. It does not appear to apply to the 17z-F series. This guide instructs to remove the bottom service panel which I could have figured that out on my own. However, the 17z-F series does not appear to have any removable panels at all. I took an up-close look at the Pavilion 17z-F100. And, it does not have any removable panels on the underside, except for the battery. So, I presume the 17z-F200 to be the same.
I am a computer technician. And, this is the first laptop I have seen without any service panels. I am probably going to have to disassemble the entire outer-shell to install memory (or to replace the hard disk drive once the time comes). But, every laptop I have worked on in the past had its own special array of hidden screws or special tricks for disassembly. So, having a maintenance guide is a necessity to avoid damaging plastic mounts, clips, guides, etc.
This question was solved.

How about this one:
Pavilion 17z Manual
Don't get me started on this. It's one of my pet peeves, too. HP is not the only one doing this. Acer and Toshiba, etc. also are selling "closed" systems now. I hate it. I will absolutely never knowingly buy one but I am spending a lot of time here answering questions just like this. Good luck and let us know how you do. Sounds like you will be fine.
