Those mainboards in the wiki are all that we (let's say the "useful" members of this community) have experience with. Sure people have tried other motherboards as well, but they can't seem to bother to share that experience with the rest of us. Maybe some of them would like to answer your question, but I doubt it.
Thanks for bringing the count up to 9 totallymaxed. I'm a bit surprised you had no trouble with SATA on that mainboard, then again I suspect it's also related to the amount of memory used (or maybe even the drives). Anyway the support for the SB600 SATA controllers should be fixed by the newer kernel in the upcoming 0710 release for once and for all.
Hi Zaerc. The Gigabyte_GA-M61P-S3 seems fine with two SATA drives attached. We will 'load it up' with two more in the next few days and i will update the Wiki page if it causes any problems. I have also been testing it with 0710 today and it seems to run equally nicely. Hmmm... I think we have the Gigabyte_GA-M61P-S3 configured with 1Gb RAM at the moment (I'll check that in the morning though).
I plan to put some more MB's up on the Wiki by the weekend hopefully.
