He managed to recover all of my data onto an external 2Tb Toshiba drive (thank goodness) BUT he tried to reinstall Big Sur with no luck either. On Monday, I took my iMac to a repairer who did an excellent job in updating my iMac with a Samsung 2Tb SSD drive and maxed out my RAM. The bottom line is that having spent around 10 hours trying to reinstall big sur I kept getting the message 'application denied'. I contact 4 apple support people who were helpful, we went through diagnostics, recovery etc etc. I tried over and over again to reboot with no luck. On rebooting it progressed to around 50% and stopped.

Last Saturday my 2017 iMac 4k retina, crashed using the lasted Big Sur update.

Should you encounter a chipset that doesn't work, please let us know by following the instructions under the "Support" section in the help manual. While testing has been performed on approximately 20 different motherboard chipsets, we believe the following chipsets should work without any problem. Such as the module thickness, module width, maximum operating temperature and more. RAMMon displays the values stored on RAM module such as the memory capacity, the manufacturer, serial number, model part number, the CAS latencies supported and the module voltage.Īlso, depending on your RAM type, other specific SPD data can be retrieved as well. The SPD standard is intended for use on any memory module, independent of memory technology or module form factor. Serial Presence Detect (SPD) is the standard set forth by JEDEC for a host system to retrieve attributes of memory modules. This information provides a snapshot of the available data for each RAM module installed on the system. It uses SysInfo DLL SDK to gather the SPD attributes from RAM devices. RAMMon allows users to identify a multitude of attributes, of which, includes the manufacturer, the clock speed and other data of their DDR2, DDR3, DDR4, DDR5, XMP and EPP memory devices and even some older memory types.
