RE: Re: Ross RT625 in SS20

That indeed has been my experience! Mind you, the 166MHz modules run very hot, so be careful if you have *two* of them in the SS10. They were orginally specified by Ross for the roomier and better-ventilated HyperStation systems.

A good de-dusting of the SS10 PSU vents etc before you start is a wise precaution.

<http://mbus.sunhelp.org/systems/sun/ss20.htm> says you need 2.25R
only for the 'D' version of the HyperSPARC.

<http://mbus.sunhelp.org/modules/index.htm#hyper> says the 'D' version
are all 180 MHz or higher.

I read this as, if your HyperSPARC are 166 MHz or lower, 2.25 should be enough.

Cordially,
