Hi!
Consulting http://www.intel.de/content/www/de/de/support/solid-state-drives/000017245.html the Firmware of your Version is current, since there is an older Version 4PC10362 listed as the most current version.
However, this doesn't answer your question completely, since hp might provide even more current firmware-versions.
On my system the firmware version is the same as yours, 4PC10365, the only difference being: I already DID install the firmware upgrade!
There is another problem with the firmware upgrade 1.20 from the hp-downloads-site:
Installing this upgrade is working fine until necessary reboot: Reboot fails every time, producing an error 0x0000098 "application missing or corrupt", when the file loadvf.bin from the upgrade-directory should be booted.
I am worried that the firmware-upgrade might not be complete.
Intel-Tools all state that the firmware is fine and current, perhaps because they check for the older Intel-Version.
My Install of Windows X64 Pro is an EFI-Install. Might that cause the problem?
