LSI SAS Controller brings RAM Issue

[Bernd83HN]

Hello,

i have a Z600 Workstation. newest (3.61) BIOS.
2 X5650 Xeon CPU´s and 48GB of total RAM

The Workstation works fine. but when i put my LSI 9270 Raid Controller in it.
I become a bootfailure that the RAM in slot 1 CPU 1 is incorrect.

I tried all diffent BIOS setting. i also tried to dissable the Option ROM from the RAID.
then the controller shows not at boot up but the failure is still there.

I tried diffent FW Packages of the Controller from LSI/Broadcom.

The Controller works also fine.

When i pull out the Controller, the RAM Failure is gne and all 48GB works fine.

Has someone a Idea?

Regards from Germany

is this a retail or OEM 9270 controller?

i have seen this issue with dell perc controllers and it's caused by the controllers custom firmware conflicting with the HP motherboards Bios/SMbus 

if your problem is this you need to cover two pins on the  card 

The pins you need to mask are:

B5 (SMCLK, SMBus clock) an B6 (SMDAT, SMBus data)

this link shows the pins

I´m not at Home but i think it´s a M5110 Card.
but i Flashed the FW Package from LSI direct.

I Don´t know if the Update erased complet all old data on the card or only Updated the FW part.

i will try your Tip with the PIN´s

Thank u very much

If your card is a OEM (IBM M5110), it will have the SMBus issue (which is why this was my first question)

note that retail LSI 9266/9270 cards will not have this problem as their firmware is a bit diffrent, and crossflashing LSI firmware does not replace all of the cards onboard firmware, only parts of it

note also that flashing the LSI firmware will not remove the need to use any IBM option keys (if used on this series card)

the generic LSI keys will not work, you must use the option keys from IBM to enable optional features on this card

the card will still register as a IBM card indevice manager as the device ID is hard coded and not affected by replacing the firmware with the generic LSI firmware

update: the M5110 card uses a LSI SAS2208 chip making it a very close clone of the LSI LSI9266 not the 9270 as the 9270 does not need feature keys to enable options, as they are allready enabled
