Serverworks chipset config on P3TDE6 ?

I have a couple of P3TDE6 in workstation use. The chipset and memory runs pretty
warm. I believe that this is mostly a result of constant cycling through memory
looking for ECC faults and rewriting if found. I understand that this is a feature
in a high-rel server, but in my workstation application it is more valuable to
reduce the power by slowing or stopping this hardware process.

Anyone know of a runtime utility or BIOS option that can change this ?
