The latest driver for your adapter is dated 08/20/2008 and is version number 126.96.36.199. The software updates that you see posted on intel.com are compatible with older adapter designs like yours, but the driver component for your adapter is very stable and no longer gets updated.
The other software in the package does get updated. The exact files updated in each package are mostly focused on adding support for new adapters and adding support for features that are available in the latest hardware. Although many components of the package are updated each year, the driver for your adapter is not one of components that is updated.

That explains it. i was expecting if a package was dated 2010 then the driver should have been updated.
I will open up a case with support on the card in general then.
I've found that when receiving very large transfers (300+GB) that the NIC eventually slows to a crawl.
It will start out transferring at over 20MB/s then eventually drop down to 1-2MB/s
On the destination server that has the NIC i have all offloading enabled, i've doubled the receive descriptors and haven't seen much help.
The SYSTEM process will use up 50-70% of the cpu, process monitor shows something related to mmisdriververifying
It is a decent server, quad core xeon CPU, 8GB of ram. Storage is a high end adaptec card with a 6 disk RAID10 array.
