allready checked that: look here:
http://www.dell.com/support/drivers/us/en/04/DriverDetails?DriverId=R269683&FileId=2731095787&DriverName=Dell%20PERC%20H800%20Adapter%2C%20v.12.3.0-0032%2C%20A02&urlProductCode=False

latest update is july 2010. i've been down this road with dell many
times and I would advise RMAing the whole server -- that will at least
get their attention. dell performance/software support is worthless
and it's a crying shame blowing 10 grand on a server only to have it
underperform your 3 year old workhorse.
