MY first PC i built with a 7070s matsonic board....Couldn't OC if its life depended on it. Also i was getting a oddball memory errors on boot up, but couldn't figure out what the hell it was for the life of me..
Not to mention that VXD errors were pretty common during the Matsonic days, when to a slightly better MOBO company(Abit - notice i said slightly..

..) and haven't seen any yet..
Edit should acctually mention that i'm still using the board in my Linux Box..Works OK there, but it not exactly OC'ed.
