The most current BIOS, as of today, is 5112:
However, and just to be 100% sure, before you update the BIOS, try the following:
Restart the system into BIOS by pressing <F2> during the boot process. Once in the BIOS setup utility, press <F9> to restore BIOS default settings. Reset any customized BIOS settings. Clear all DMI event logs by setting the option to "Enable", which is located in the Advanced/Event Log Configuration section of the BIOS Setup utility. Press <F10> to save the new settings and reboot the system.
A golden rule:
Don't upgrade the BIOS if there are no problems related to the current installed BIOS.
New BIOS means that a known bug may be solved, but then can be also introduced a new bug.
so, don't fix if it ain't broken.
In your case, switch back to an older BIOS.
