This is an occasional issue that can happen after a long period of use.
Some cameras when formatting the card create a multiple File Allocation Tables (FAT). If the camera has formatted the card a number times the space used by these tables will have increased and therefore the available space for saving images will have been reduced.
To fix this, use a card reader to reformat the card using the DOS 16bit FAT. Remember to have downloaded any images you wish to keep before hand, as this will destroy all data saved on the card.
SD and MultiMediaCards are very similar in size and design but there are some differences.
technological advancements over MMC. These include the addition of cryptographic security protection for copyrighted data and a 4X increase in data transfer rates. To help support higher-density capacities, SD cards are slightly thicker than the original MMC cards. This means that most devices designed to support SD are also backward compatible to MMC cards, but devices designed only for MMC will not support SD. To confirm compatibility please see our flash selector.
Before using your flash card with your digital device, you must format the card in the device. Details on how to format the in your device can normally be found in the user manual.
CompactFlash (43W x 36H x 3.3D (mm)) is a NAND based flash memory storage device. CompactFlash does not require a battery to retain data. The cards have a 50 pin interface and comply with the PC Card ATA specification. CompactFlash cards, are a solid-state hard disks.
CompactFlash is rugged and reliable and is used in a variety of applications including PDA's, digital cameras and notebooks. The cards are made to operate with dual voltages (3.3 & 5V). Current capacities include 16MB, 32MB, 64MB 128MB, 256MB, 512MB, 1GB, 2GB and 4GB.
This is a speed measuring system adopted from the CD ROM industry. A 20X card is not 20 times faster than a standard card, which would be say 6X. It is in fact 2.5 times faster (1.2MB/s V 3.0MB/s). Actual speed results depend on the device.
The USB Flash Drive has two partitions on there. One is a 1.44MB size (size of the floppy disk) and the other is the remainder of the flash memory.
If your PC/MAC is not showing both partitions then there could be one of two things wrong (not serious).
1. On the side of the pen is a write-protect switch. Move the switch to the unlock sign and plug it into your USB socket. You should now have two drives in Windows Explorer. Make sure that you eject the device safely before moving any switches.
or
2. Issues arise when you already have an F drive assigned for a device (hard drive, CD-ROM, external device, etc). We recommend that to you if you are working in a company plug the USB Pen Drive in first and then switch on your computer and login as usual. If you already have a F drive assigned on your office computer locally on your machine you must change that drive letter. I advise that you speak to your Network Administrator for that.
If you are a home user (not logging in to a company domain), if one of your devices is assigned as an F drive, change this to a different drive letter.
Under Red Hat Linux v7.3 (kernel v2.4.18-3) the steps are as follows:
1. Format the USB Flash Drive (UFD), JetFlash, or JetFlashA as a FAT file system in Win98SE.
2. Create a directory in /mnt called "flash".
3. Mount -a -t msdos /dev/sda1 /mnt/flash. Linux recognizes UFD, JetFlash, or JetFlashA as a SCSI device; therefore, you should see it listed as "/dev/sda", "sdb", etc.
The reason for this error message is because a password has been applied to the USB Flash Drive using the Security Application that was supplied with the product (on the CD that was supplied and on the floppy partition of the USB Flash Drive).
If you have put a password on the device this will not allow you access to the USB Flash Drive without the password. You will not be allowed to format, or do anything with it.
You will need to use the same software to apply the password to unlock the USB Flash Drive and gain access to the device again.
When this device is used with the Security Application the larger partition will become the PRIVATE area and can only be accessed using the Security Application and the smaller partition will be the PUBLIC area which can be accessed at all times.
Be warned that if you enter the password incorrectly six times it will format the USB Flash Drive and will wipe it clean. You will NOT be able to recover the data.
The default file system of JetFlash is "FAT16". If you wish to copy more than 130 files at a time, use your computer to reformat your JetFlash as "FAT32".
For a single-card device or Pen Drive, no driver is needed. However, both types of devices need USB support for 1.3.x or above. If using Mac OS 8.6, you can check the level of USB support by selecting USB Support in Extensions in the System Folder and Get Info (in the File menu). Please see http://developer.apple.com/hardware/usb/versionusb.htmf or more info.
If you are still having issues with the SD card after applying the patch, it is possible that the Tungsten T3 damaged the card. Please contact Technical Support who will help you with this issue.
Before formatting the card the N-gage mounts the drive. If you cancel the format or you lose power to the phone before the format has completed, the phone does not dismount the card.
To solve this need to reformat the card in another device such as a camera and then reformat it in the N-gage.
When the phone loses power whilst it writing to the MMC card during.
1. Taking a photo
2. Deleting a photo
3. Formatting the card.
It is possible that the File Allocation Table (FAT) will corrupt. You will need to reformat the memory card. This is normally achievable on your phone, or you can use a reader connected to your PC. For information on how to format the card in your phone please see your user manual.
When memory cards are used in mobile devices such as mobile phones they draw power, which affects battery life. Generally, the lower the voltage of a memory card, the less current it will draw to operate leading to a longer battery life. This is becoming more important with 3G/2.5G Camera Phones and Smart Phones.
Currently, MMC (MultiMediaCard) and RS-MMC (Reduced Sized MultiMediaCard) are 3.3 V (Range: 2.7V to 3.6V). They are also both 7-pin.
There are new DV (Dual Voltage) versions, DV-MMC and DV-RSMMC (both 7-pin) these operate at 3.3V (Range: 2.7V to 3.6V) and 1.8V (1.7V to 1.95V). The cards are designed to work in current devices and new dual voltage and single voltage devices.
Some new devices will only operate at 1.8V. Therefore they require the DV version of the card.
The Nokia 6630 is one of the first devices that will require DV-RSMMC - current non DV-RSMMC cards will not work. Other mobile phones that require DV-RSMMC are the Nokia 6680, Nokia 6681 and Nokia 6682.
In younger machines that are using either SDRAM or DDR SDRAM, you will be able to install modules of different sizes without any compatibility issues. For example, if your computer currently has a 256MB memory module, you would be able to add a 512MB module for a total of 768MB of RAM. However, within DDR machines if you have a "dual-channel" motherboard and want to take advantage of this technology, you will need to install the modules in matched pairs.
This problem my have been caused upon installation for your new memory module by knocking a cable within the machine. For a machine to be able to boot a complete circuit need to be made. To solve this issue all of the connections within the machine will need to be inspected to ensure that they are in the correct location securely.
If this doesn't help, please contact us at support@offtek.co.uk or phone on 0800 698 4100 and select the option for technical support.
CAS latency is the amount of time between the memory receiving a read request and the first piece of data being output from the memory. Latency is measured in terms of clock cycles. A CL2 module takes 2 clock cycles to respond to a command and a CL3 modules takes 3. After the first piece of data, all future requests are processed at the same speed, therefore the difference in performance between CL2 and CL3 modules is negligible.
Some motherboards use a system that divides the memory slots into banks. Your system may or may not use banks. If your computer has eight 30 Pin Memory slots they are probably banked into 2 banks of four slots. If your system is banked you will need to fill each bank with matching pairs of SIMMS. These banks are usually numbered, such as bank 0 or bank 1.
As a general rule, on a 486 based system, each socket operates as 1 bank, therefore 1 module can be installed at a time. # Modules must be installed in pairs for Pentium based system that use 72 Pin Simms.
168 Pin and 184 Pin Dimms can be installed in single pieces. Rimm modules are installed in pairs with motherboards that have 4 memory slots but can be installed in single pieces on motherboards that have 2 memory slots.
If you have a "dual-channel" system and want to take advantage of that technology, you will need to ensure that the modules in each memory slot are the same density.
Unfortunately there can also be times when installations slow down the machine. If you have come across this problem then the likely cause will be that the machine does not have enough Cache to handle the extra memory. Therefore in order to upgrade the machine you will need to first obtain a new motherboard.
EDO (Enhanced Data Output) and FPM (Fast Page Mode) modules can be buffered or unbuffered. Buffered modules contain a buffer to help the motherboard cope with the electrical load when the system has a lot of memory.
DDR (Double Data Rate) and SDRAM (Sync Data Random Access Module) modules are either unbuffered or registered. Registered modules have a register that delays the transfer of data by one clock cycle.
Unbufferred modules are generally found in desktops and laptops. Bufferred and Registered modules are typically found in servers/workstations where data is extremely important.
By adding more memory to your machine you are allowing the system to use the memory as and when it needs to. If you are running intensive memory applications such as games, image software or large databases then the more memory you have installed the quicker and easier the system can cope with the data processing requirements.
If you have installed a memory upgrade and you cannot see any performance advantage you may find that they system does not need to utilise the memory for the applications that you are using. Also take into consideration that memory is not the only upgrade available to increase the performance of machines.
If you have begun to see your machines system performance start to slow down and you can also hear the hard drive working constantly then you will need to upgrade your memory.
The hard drive is working overtime as there is not enough RAM memory for the system to use in order to complete its tasks. Therefore the system is sending information to and from the hard drive to accomplish this. As RAM memory works faster then hard drives the system performance will therefore seem slower.
For EDO or FPM modules you will see with Parity or Non-Parity modules. Parity modules detect single-bit data errors.
With SDRAM and DDR modules you will see ECC or Non-ECC modules. Error correcting code (ECC) modules detect and correct single-bit errors, but they also detect and report double-bit errors.
It is very straightforward to add memory to a machine. The task generally requires you to locate the memory expansion slots on the machine, push the memory into the expansion slots and then re-boot the machine. The system will then recognise the memory automatically.
A 168 Pin Dimm is approximately 5 ¼ inches in length and 1 inch in height and contains 84 Pins on either side. It is referred to as a 168 Pin Dimm because it reads both sides of the Dimm simultaneously. The Dimm is different from the Simm in that it has two notches on the contact edge and inserts into the socket straight down, without the need for tilting. Dimm sockets also have release tabs at each end which acts as a lever to push the module up out of the socket during removal.
There are several different flavours of Dimm, including FPM, SDRAM (7, 8,10,12 Megaherz), EDO (Buffered, Non-Buffered, 3.3V & 5V). ECC (Error Correction Code) and Registered. It is imperative to select the correct type of module when upgrading and memory search facility located on our home page will identify the correct upgrades for your model.
As a general rule, SDRAM is backwards compatible, therefore a PC133 Dimm can operate at 133Mhz, 100Mhz and 66Mhz. Certain systems though that require 66Mhz SDRAM modules will not accept PC100 or PC133 modules. In addition to the speed, the chip configuration of the module is also important. Use our memory search facility located on our home page at (http://www.offtek.co.uk) for guaranteed compatibility.
2-clock SDRAM refers to the first generation of SDRAM that used 2 CK, or Clock lines, to synchronize the memory chips with the motherboard. The important thing to note is that systems that require 2-clock SDRAM won't accept 4-clock SDRAM and vice versa.
A 184 Pin Rimms is approximately 5 ¼ inches in length and 1 inch in height and contains 92 Pins on either side. 184 Pin Direct Rambus Rimm Modules delivers pure performance where it matters most: leading-edge applications. RDRAM's 32 bank architecture supports up to four simultaneous transactions per device. Clock frequency currently offerred include 800Mhz and the latest 1066Mhz modules.
A 232 Pin Rimm is approximately 5 ¼ inches in length and 1 inch in height and contains 116 Pins on either side. 232 Pin Direct Rambus Rimm Modules (PC4200 - 32bit) are an industry first high-speed RDRAM module. The module has a 2-channel feature boasting record operating speeds of 4.2gigabytes per second (GBps). This is 4X faster than a conventional SDRAM module and 2X the performance of DDR SDRAM module. Present RDRAM based PCs are found with single channel modules that normally has at least two modules working as a pair. In contrast, the RIMM4200 module can be installed in single pieces which facilitates easier memory upgrades for the end user.
A 184 Pin Dimm is approximately 5 ¼ inches in length and 1 inch in height and contains 92 Pins on either side. 184 Pin DDR Dimms are designed for the latest desktops and servers. Each 184 Pin Dimm provides a 64-bit data path, so they can be installed singly in 64-bit systems. To use DDR memory, your system motherboard must have 184-pin DIMM slots and a DDR-enabled chipset. DDR SDRAM (Double Data Rate-Synchronous DRAM) is a type of SDRAM that supports data transfers on both edges of each clock cycle, effectively doubling the memory chip's data throughput.
DDR memory has been manufactured to be backward compatible so you can add faster memory modules to your machine. For example, if you install a PC3200 module alongside an original PC2700 module the memory will wor and be fully compatible but you will not gain any performance benefit, as the PC3200 module will be clocking down to PC2700 to run alongside the original PC2700 module installed.

Dual channel refers to the DDR/DDR2 chipset on specific motherboards that have two memory channels. Motherboards with this feature can provide upto an additional 10% performance improvement. In order to take advantage of this technology you simply need to order and install the modules in pairs but they must be exactly the same specification to perform correctly.
DDR2 memory modules are currently offered in three frequency ranges, 400MHz, 533MHz and 667Mhz.
240-pin DIMMs are used to provide DDR2 SDRAM memory for desktop computers. Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered modules), so they are installed singly in 64-bit systems.
240-pin DIMMs are available in DDR2 PC2-4200 (DDR2-533) SDRAM or DDR2 PC2-3200 (DDR2-400) SDRAM. To use DDR2 memory, your system motherboard must have 240-pin DIMM slots and a DDR2-enabled chipset.
No, DDR2 DIMM memory modules are not backwards compatible with DDR DIMM, due to incompatible pin configurations, core voltage, and memory chip technology. DDR2 modules are designed with a different "key" in the edge connector to prevent insertion into incompatible memory sockets such as DDR motherboard. A DDR2 SDRAM DIMM will not fit into a standard SDRAM DIMM socket or a DDR DIMM socket. DDR2 modules use a 1.8V power supply, providing a big power saving over the 2.5V DDR modules.
A 200 Pin DDR SDRAM Module is approximately 2.625 inches in length x 1 inch in height and are designed for the latest laptops. Each 200 Pin module provides a 64-bit data path, so they can be installed singly in 64-bit systems. DDR SDRAM (Double Data Rate-Synchronous DRAM) is a type of SDRAM that supports data transfers on both edges of each clock cycle, effectively doubling the memory chip's data throughput.

Manufactured using premium brand chips from Samsung, Hyundai, NEC etc.
A 144 pin SoDimm is approximately 2.625 inches in length and 1 inch high and are commonly found in laptop computers. Each 144-pin SODIMM provides a 64-bit data path, so they are installed singly in 64-bit systems. 144-pin SODIMMs are available in EDO, PC66, PC100 and PC133 SDRAM.
A 144 Pin SDRAM MicroDimm is approximately 1.545" x 1 inch in height and is designed for laptops. Each 144-pin MicroDimm provides a 64-bit data path, so they are installed singly in 64-bit systems. 144-pin MicroDimm are available in PC100/PC133 SDRAM.
A 172 Pin DDR MicroDimm is 1.75" in length x 1.25" high and is designed for laptops. Each 172-pin MicroDimm provides a 64-bit data path, so they are installed singly in 64-bit systems.
