first time post for me so I hope I get it all right and dont forget any important details.
I disapprove of overclocking, so please consider all information as operated at default speeds (besides who'd overclock such a system anyway?!)
In addition I seem somewhat addicted to updating all my hardware to the latest firmwares, regardless required or not. Hence rest assured every flashable device in my machine is up-to-date.
Settings of all components are down to manufacturer's defaults, except for onboard storage controllers of any kind which I deactivated.
Just a few specs on my workstation's interior:
S5520SC Board (FW Rev. 55;55;30;112, PBA-Rev. -304)
2x X5680 processors
1x 4GB ECC Reg Hynix DDR3 @ Slot A1 (approved by official compatibility list; just to get it running)
Adaptec 5805 RAID PCI-e 8x SAS/SATAII (FW Rev. 5.2.0 Build 18252, controlling 6 x 1.5TB Seagate SATAII HDDs)
Using onboard VGA
...which is about it really. Before I beef it up with all the neat extras (Dual gfx, RAM galore, etc.) I want to make sure the base components work as expected.
...which they DON'T do as you might guess
In particular the RAID HBA is giving me the hikkups.
The whole box boots and runs just fine when the RAID adapter is operated in either of the two PCI-e x16 Slots; I can enter Mainboard-Bios, RAID-Config, install software, all peaches n cream.
BUT since I am planning to use the x16 slots for a dual gfx solution in future, I dont wish to use my RAID adapter in there.
Thus I slipped it into the x8 mech. slot and what do you know?! Black Screen....
Box is up and running though. CPU fans spinning like mad, status LEDs all green. Ready to fire up actually. After waiting for half an hour (the adaptec ROM is renowned for extensive loading time) I cut the power.
I forgot to mention: No onboard SAS module present, PCI-e x8 mech. should be available.
Another indicator for a compatibility issue is the fact that the RAID adapter has a row of red status leds (pretty much resembling the moving "eye" of a well known black Trans-Am) moving left right while the Adaptec ROM is loading. When seated in the x8 slot it suddenly halts right in the middle of the booting process never to move or blink again.
No error beeps no error codes by the MB's status leds...
I'm forlorne and fear that either the x8 slot is totally incapable of hosting RAID adapters (conflicting with onboard SAS-functionality?!) or the adaptec refuses to operate in x4 elec. slots. Latter seems unlikely though, as prior to the S5520SC I used the adapter in a DX48BT2 "Bonetrail" (in x16 mech. x4 elec. PCI-e slot) with no problems at all.
Any experiences with similar configs or help of any kind is extremely welcome.
Thanks alot & kind regards,
