What do I need to do to make DRAMs work properly in Dual Channel mode?

Make sure that the memory is built on the same chip organization and is installed in correct slots, marked with the same color. The first module should always be places in the first slot located closest to the CPU

What is the difference between the Single Rank and Dual Rank modules?

Single and dual rank are terms describing one of the features of the memory module construction. Mounted on the memory module they are grouped in ranks, the amount of which depends on the number of systems used and the type of PCB. Consumer modules usually have one or two ranks. Due to the requirements of the motherboards being the basis of each computer, when purchasing memory modules, pay attention to the current configuration of the computer, read the motherboard’s manual, and then select the correct module. Newest models of motherboards are mostly characterized by proper cooperation with single and dual rank modules regardless of module installation slot.
GOODRAM single rank memory modules have an additional code in the product code in the form of the letter S before the mark /.

New module is not working. What could be the reason?

Problem with a proper operation of new memory module may be due to the following factors:
– Incompatibility between memory and motherboard (incorrect capacity, organization, speed)
– BIOS error
– Memory failure
We recommend that you check the device compatibility and BIOS settings for the given memory configuration in the first place.

I have a memory module from different brand. I would like to expand my memory by installing GOODRAM memory modules, but doubt if modules manufactured by two different brands will cooperate with each other?

If your motherboard/processor supports a particular memory type, then adding another memory from other brands is usually not a problem. However, for the memory to work properly in dual channel mode, it is recommended to install two modules of the same type, i.e. with the same capacity, timings and organization (single-sided or double-sided modules). GOODRAM recommends memory modules with DC marketing, that are specially paired for dual-channel operation during the production phase.

What are the brands of memory chips GOODRAM is using for their modules?

We build our modules using the components manufactured by the world biggest chip companies like Micron, Hynix, Nanya and Samsung.

How do I check whether memory modules work with a particular motherboard?

You can check this information by going visiting the motherboard manufacturer’s website. There, you should find a specification of memory modules that are compatible with your motherboard.

The memory capacity available to the user is different from that specified by the manufacturer. Why is this happening?

The actual storage capacity of solid state drive depends on the technology used. In the case of newer NAND FLASH technologies, the controller reserves space for the operations and execution of tasks that happen during the use of drive. As the latest NAND flash memory require larger system structures, the controller uses additional space to ensure correct operation of the wear levelling algorithms. In practice, this means longer SSD lifetime, optimized memory performance and significantly increased data security.

Exactly how much is the factory space for over-provisioning?

The value of over-provisioning on SSD GOODRAM is fixed at 7% rounded.

Why SSD is freezing my operating system?

Very often sudden freezes may result from driver issues or power management services within the operating system. Another reason may be that the drive is under massive load, causing internal garbage collection mechanisms to slow down the drive’s operation. These mechanisms are activated in idle mode, but there may be cases when they operate while the drive is in use. If you are experiencing such problem, do not hesitate to contact us.

Is the GOODRAM SSD warranty limited by TBW?

Yes, the warranty for GOODRAM SSD is limited by the TBW value.

Is the SATA III SSD compatible with a computer that supports SATA II only?

Yes, the drive will be compatible with the SATA II interface, but its performance will be limited to performance, provided by SATA II interface.

When connected, memory card shows 0 MB of usable capacity and asks for formatting every time. What should I do?

First, please try to use your memory with a different device and also make a backup of the data to avoid data loss. Try deleting the partition and creating a new one. The partition can be removed / created under Windows operating system, e.g. with a free Active@ Partition Manager application. Under Windows Vista/7/8, you can use a system tool called Diskpart. Under Linux, you can use Fdisk, GParted, or other similar tools

Memory card cannot be formatted, I can’t perform any operations on files, saved files are missing or files rename themselves. What can I do?

If the memory card enters read-only mode, it means it’s damaged. In this case, please file a complaint at the place of purchase of the product. If you experience any issues with saving files, the memory card can be checked, for example, with the free Flash Drive Tester by performing a read/write/compare test.

Memory card is not detected by computer or other device. What can I do?

Check if the Windows operating system has assigned a drive letter to the memory card. You can check it as follows:
Click Control panel -> Administrative tools -> Computer management -> Disk management and assign the drive letter manually if needed. If the problem persists check the memory card on other device. If the problem also occurs when the memory card is connected to another computer or device, it may be damaged.

I have a problem with writing a file bigger than 4 GB to a memory card with higher total capacity e.g. 8 or 16 GB.

First, please make a backup of the data to avoid data loss. Then format the memory card using the exFAT or NTFS file system. FAT32 has a single file size limitation. The file cannot be larger than 4 GB, so that’s why there are limitations in uploading large files.

Operating system doesn’t allow the access to my flash drive?

First, please make a backup of the data to avoid data loss. This problem may be caused by a virus blocking access to the flash drive. In this case, we recommend performing a system scan using an antivirus software or removing or formatting partition e.g. under Linux operating system. The second option is to format it using the tools provided by Windows operating system. Flash drive should be formatted in FAT32 or exFAT file system. No special software is required for formatting.

Files disappeared from my flash drive and are not visible but the occupied space remains the same.

This can be caused by a virus and we recommend scanning the USB flash drive with an antivirus software. To access locked files, please follow the following steps (for Windows only):
Determine the name (letter) of USB flash drive/memory card e.g. “d:”, “e:”, “f:” (you can check it in My Computer section)
Select Start>>Run. Enter: “cmd”
Type you drive name e.g. “d:”, followed by the “dir /ah” command. You will see all hidden files.
To access locked files, type in “attrib [name of file/folder] -r -a -s -h”.
