Fat alloc error


> FAT ALLOC ERROR

FAT == File Allocation Table (like a 'Table of Contents' in a printed book)

ALLOC == Allocation

ERROR == ERROR

Some of the contents of that 'Table of Contents' are invalid.

So, copy all the files from the Memory Card onto your computer, to save a copy of those files.

Burn a CD/DVD disk with a copy of those files.

Then, "reformat" the Memory Card, to write a "new" and "empty" 'Table of Contents' onto the device.
Then, copy all the files back onto the Memory Card.

Added 1G memory, for a total of 2GB. the system still only sees 1G


If you installed total 4GB memory, the system will detect less than 4GB of total memory because of address space allocation for other critical functions, such as:

- System BIOS (including motherboard, add-on cards, etc..)
- Motherboards resources
- Memory mapped I/O
- configuration for AGP/PCI-Ex/PCI
- Other memory allocations for PCI devices

Different onboard devices and different add-on cards (devices) will result of different total memory size.
e.g. more PCI cards installed will require more memory resources, resulting of less memory free for other uses.

On a SLI system, since PCI-Ex graphic cards will occupy around 256MB, another 256MB will be occupied after you install a 2nd PCI-Ex graphic card. Hence, 2.75GB memory left only if two SLI cards installed on A8N-SLI Premium while 3.0GB memory left with one graphic card without other add-on devices.

This limitation applies to most chipsets & Microsoft Windows 32-bit version operating systems.

If you install Windows 32-bit version operating system, we recommend that you install less than 3GB of total memory. If more than 3GB memory is required for your system, then below two conditions must be met: 1. The memory controller which supports memory swap functionality is used. Chipsets later than Intel 975X, 955X, Nvidia NF4 SLI Intel Edition, Nvidia NF4 SLI X16, and AMD K8 CPU architecture support memory swap function. 2. Windows 64-bit OS which can address more than 4GB memory. You can check below URLs for reference:

I am lookng for a increase in graphics in my acer aspire 4315


The video card is part of the motherboard and cannot be up graded.
The video RAM uses part of the main RAM but you might be able to increase the allocated video RAM to the max configuration in the BIOS.
Refer to the video specs I copied for you.
Video
  • Graphics Processor / Vendor Intel GMA X3100
  • Video Memory Dynamic Video Memory Technology 4.0
  • Max Allocated RAM Size 358.0 MB

Hey there, I have an Acer Aspire 7720. I checked in BIOS (v1.25) that only 8MB video memory is avaliable (out of 2GB), and couldn't change the settings. Could you help me solve the problem please?


dynamically allocated memory is borrowed from the system memory; ie, your GPU is using shared memory. Increasing the allocated VRAM is not going to increase your performance by much simply because this kind of video memory is so slow.

You might want to consider updating your graphics driver and checking your temps to make sure that the GPU isn't overheating.

Limited memory for anniversary-calendar


Hi. You can't actually increase the memory for this feature, as most modern mobile phones now use 'Dynamic Memory'. This means that there is a pre-allocated maximum amount of memory for each individual feature, based on what most would be expected to use. For example, much more memory is pre-allocated for Games, Music, Photos, and Text Messages, than for less popular applications like a Reminder or a Calendar. This is why most camera phones have a Memory Card Slot, as the manufacturers know that people will often need extra memory space for photos. What you can do however, is to buy the largest memory card that your camera phone will support, and store most of your photos and music on it, keeping lots of space on your phone for other things.

Toshiba L305-S5907 how to increase video memory allocation


Ok, so I talked to a toshiba rep about this (i have a satellite l305-s5911). And what you need to do is restart your laptop, and press ESC+F2 at the same time. It might take a few tries. If that isn't working try pressing F2 repeatedly at the first screen you see when starting your computer (not windows vista screen).

From there you'd be in the internal menu, and you can change the video settings. 

Be FORWARNED the rep also told me that if you happen to change the wrong setting, it MIGHT (not likely though) void you warrenty

Hi rnb brother,

It sounds like you may need to udate you BIOS. It may be a memory allocation issue. This is an issue when the accessed/pointed memory allocation does not totally close, allowing a little bit of info out to disrupt normal operation. BIOS is closely related to access/pointed memory allocation and upon udating will close this path competely. I hope this helped a little, if not, hit me back, we have other options i.e. running dual cards.

Thank you for using FixYa.com
