Your memory upgrade did not provide the expected result? Here you may find possible reasons for the most occurring problems when upgrading memory. Please check, if one or another below mentioned reason can help to solve your problem. Otherwise, our support team will be pleased to take further technical measures using the information you obtained through the performed tests.
- Did you consider the configuration guidelines of the system manufacturer?
- Are BIOS, operating system and driver up-to-date and set correctly?
- Please remove the memory module and install it again
- Is your system running stable? Test your RAM!
- Refine your diagnosis!
- Your OS does not recognize more than 4GB of memory even though you have installed more?
1. Did you consider the configuration guidelines of the system manufacturer?
Before installing new memory modules, it is absolutely necessary to read the documents provided with the device by the manufacturer/distributor (manuals, homepage of the manufacturer, etc…). Often, there are specific configuration guidelines, which need to be considered when upgrading with memory modules.
You should pay attention to the following:
- Is there a certain order to follow when equipping the slots?
- Are there any restrictions or guidelines on how and if different modules or kits can/ should be mixed?
- Please check if our website contains specific references about your model.
2. Are BIOS, operating system and driver up-to-date and set correctly?
Basically, manufacturers of a computer system expect the BIOS version to be up-to-date before any installation of new hardware. While there are many cases where a BIOS update is unnecessary and the system runs stable after the installation of new hardware, a BIOS update is the first method of choice in case of problems after or during installation.
The following symptoms are typical for an outdated BIOS and/or operating system:
- The RAM is recognised only partly by the BIOS and/or operating system.
- The system does not boot with the newly installed memory.
- During operation, reproducible crashes occur during specific applications or actions.
- The system is remarkably slower than before or freezes.
- The system is running and the memory is recognised, however, another component is not working anymore as expected.
- Recommendations for action:
- Please check possibly extended settings (ECC, Hot-Spare-Memory, Mirroring etc.) regarding your RAM in the BIOS setup for correctness.
- Should your BIOS allow settings regarding RAM timings, please make sure that these are set to automatic detection. Otherwise, false, manually set values are likely to lead to an instable system as well as harm your motherboard and the memory modules.
- Make sure that you only use the latest version of your operating system and all drivers. An extension of your working memory means that the new resources have to be distributed and managed by the operating system. This is often blocked by outdated, defective software.
- The above is also valid if your system ran stable before the upgrade.
3. Please remove the memory module and install it again.
- When function errors occur, they sometimes arise only from a mechanical contact gap! Often, dust or similar have settled on the yet unused contact surfaces of the memory slots. Just remove and insert the module repeatedly.
- Is the module really engaged?
- Is the module, resp. are the pins or the contact banks damaged?
4. Is your system running stable? Test your RAM!
- You can use the Windows Memory Diagnostic Tool by Microsoft to test if the memory, independent from the particularly installed operating system, has been integrated properly into the system by the BIOS:
- When no errors occur during the tests, that means the memory is being tested as O.K.. The error can be assumed to lie in the installation/configuration of the operating system.
You will find an instruction on how to test your memory for Windows systems in our blog.
- Alternatively, you can use the free tool Memtest86, independently of the installed operating system, for all x86 Intel and AMD platforms.
5. Refine your diagnosis
The following steps help to localise the fault quickly:
- Have the modules been installed professionally and ESD-protected?
- Module/kit runs, but not together with other, resp. the already installed memory.
- Module/kit runs, but not in a single test.
- For more than one installed module, you will find out the “right” module by using the CompuRAM method “Turn 4 into 2”.
6. Your OS does not recognise more than 4GB of memory even though you have installed more?
Please make sure that you really use a 64-bit operating system. If so, the following phenomenon may be the reason:
- The 4GB phenomenon: A part of the memory is reserved for different system resources
