this is what came back from terminal: 54 0 0xffffff7f839fb000 0x4000 0x4000 as.lvs1974.RTCMemoryFixup (1.0.3) 2107893D-2CCA-30EF-A637-18A23310C289 <36 7 5 4 3 2 1>

I take it that means its loaded? - Will find out from cold boot in the morning if its fixed. Did a start a couple of times without issues so fingers crossed.....Appreciate your assistance Justin

yes, that means it is loaded. why don't you shutdown your machine and turn it on again to verify. I am not sure if this kext could fix the problem you had, i never had that issue, though.

You could always use the MultiBeast10.4 RTC option and remove the kext you downloaded (and rebuild caches after). Worth checking because it does indeed sound like RTC.

Can you send me your DSDT.aml? or let me your current BIOS version.

Here you go - BIOS is the last proper version for the board (F7). and thank you!....
