I am interested in getting the shuttle sn25p (small size) or maybe making computer out
of a nforce4 mini-atx board. (I think that msi is making one now).

I want ecc memory support of the unregistered dimms. The Asus A8n-sli Deluxe (according to bios option and manual) and the DFI nforce4 boards support ecc (according to a review I read). It does not seem from the info I have been able to gather that the shuttle sn25p does support ecc in the bios.

From my reading of an AMD tech document on the socket 939 processor, ecc is a processor thing. So that processor does support ecc of its unregistered DIMMs.

So my question is , if the sn25p does not support ecc in the bios, if I run the A64 Tweaker utility, will it really be able to override the bios and add the ecc functionality to the sn25p? Can someone tell me technically why it should or should not be able to . What could get in the way of that on the motherboard level? Will ecc unregisted dimms work in the sn25p, during the times the A64 Tweaker is not running? In other words , will the motherboard be smart enough to not use the extra ecc chip on the dimm during initial boot up?

Can a64 Tweaker be incorporated into the boot up sequence? After the ec switch is set iin the Tweaker, can you shut down tweaker and the ecc will continue withought having to have Tweaker continue in the background?

Thanks,

Oh, and how can you tell for certain the ecc is really being used, and not just see a Tweaker switch? How does that really work? Can you tell if you run a memory benchmark without ecc, then run the same benchmark with ecc, and there should be a like 1/8th decrease is memory speed or something?

Oh, I take it, that once you shut down the Tweaker program utility, all the settings you made will continue until the computer shuts down?

Will A64 tweaker be able to start up from inside the new 64 bit windows that is being realeased?

If I wanted to run Linux or 64 bit Linux but needed the ecc switched on, could I boot into windows, switch it on though the Tweaker, then boot into Linux without hitting the reset switch. I don't know what I am talking about here. Would there be any sequence that would keep the toggles on the memory?

Thanks so much for help.
