I have an MSI MB w/ Direct OC on it, has anyone used this and how good was the results?
I figured even being a newbie here myself I could at least answer your question. First off, I assume you mean the MSI 770-G45 board, or a similar model; that's the one I have. At first, I thought that the OC switch was nice, but after some testing I found it to be useless, especially with a 955 BE (or any BE/unlocked CPU to be honest) as most of the time you'd just crank up the multiplier and you don't need to adjust the FSB. However, even if you have a locked processor and want to adjust the FSB for OC'ing, the OC switches on the mobo are still (less useless, though) inconvinient. What if you want to set the FSB higher/lower for when you are playing games or just browsing the web/leaving it on overnight or something with minimal resources? The OC switch is much more of a pain to get to than booting into the BIOS and changing the FSB speed there.
Also, besides being a pain to adjust (as you could still change the FSB from the BIOS with it on), it actually made my 955 overclock at a lower speed for the same VCore, temperature, and stability.
Hope this is something of what you were looking for
