Getting "Out Of Memory" errors?

Clarity is a 32-bit process, which means it can use the max of 2GB RAM, but if you use more than one demanding instrument, it can still be beneficial to have 8 GB RAM, so the PC has enough RAM left for OS and other apps.

In Clarity 9.1, we reduced the risk of out-of-memory events when using Agilent ICF due to improved memory usage. Operations with modules utilizing Agilent ICF are moved to a separate process so it can use another 2GB RAM. So we recommend upgrading to the latest version.

If you still get the "Out Of Memory" error, e.g., when opening a chromatogram in the Chromatogram window, it may be caused by using a particular method, which has been saved over and over again due to some modifications. Since version 8.3, every saving of such a method results in creating another method version (the number of versions is displayed at the top of the Method Setup dialog behind the method name as "- #number"). These versions increase the Method file size; memory can be depleted when such a large method is used, forcing the software to misbehave.

As a remedy:

• Try to save the method using the command Save As under a new name. This will save your method without previous versions, decreasing the file size.
• Do not use "Open chromatograms in Overlay" when running a Sequence.
• Do not open resulting chromatograms when Sequence is running (Disable the checkbox in the Open column).
