Official MSI P7N Diamond (780i) Discussion/Review/Overclock/Guide/BIOS Thread

On the striker with all 3 cards installed full load is 60-68c with fan set to manual on 80%. Of course the middle card always shows the hottest. The ss earlier the fan is set to auto. I havent touched any of that stuff yet. Yes i'm using vista 64 SP1. I havent heard of or had issues with super pi in vista 64. I haven't used it much though.

Was just checking as I know Fiskbit was having some issues with SLI and/or GPU temperatures, thank you for clarifying that. Your temp results look spot-on so that helps provide a good benchmark for determining if anybody is having overheating issues on auto. My card definitely runs hotter with this board, I imagine it has to do with the chipset more than anything; glad to see it wasn't my imagination. Guess I'll have to look into my Super PI issue some more...it makes me nervous, lol...although I passed a 2-hr run of CPU-focused OCCT last night plus loops of PCMark Vantage overnight without a problem.

Well, I wasn't having issues with temperatures, per se; I just didn't have the fan speed upped. I'm running them at 50% for the colder card and 60% for the hotter card. Current temps are 56 and 60 C, but case ambient is 5 or 6 degrees higher than usual because it's a hot day.

I had to do a complete reinstall of windows last night and will be looking at SLI again soon. Perhaps things will run more smoothly this time.

Sounds good, let us know. No new information for you, although I poked around SLI Zone a bit...only real cause mentioned was a CPU bottleneck. Oh well, keep truckin', a format is a clean slate.

Hey I just got my new pc and i am not yet used to the MSI BIOS setup lol. Its very different from my old setup. I have a Q9450 @ 2.66Ghz and i want to overclock it to about 3.5 Ghz (390x9). I cant figure out how to edit my FSB and my multiplier in these BIOS. Could someone plz help me. I know its in the cell menu but its so confusing. I know im a newb.

Also: What would be the best voltage for these settings?

[Fiskbit]

Well, firstly, have you flashed to a newer BIOS yet? The shipping BIOS is more confusing and buggy than the current available betas. I don't recall the link, but there are links to the BIOS within the last few pages of the thread. I also recommend reading through some of this thread to get an idea of what settings you'll need to achieve your goal and how to arrive at those settings. It also probably won't be as easy as you're hoping; no one can just give you settings that will definitely get you to where you want to be, as everyone's hardware is different.

If I recall correctly (I'm not looking at the BIOS right now), you highlight the FSB entry, type in a new value, and hit enter in order to enter a new value. The FSB term is four times the value that will be used with your multiplier to determine your CPU speed. It's also a good idea to run your RAM 1:1 with your FSB, so set RAM to half the FSB. To change various voltages, I'm pretty sure you highlight the item and press + or -. Be careful with voltages, as too much will cause damage.

I recommend reading through this thread; it's long, but it's a good read and you'll likely learn a lot.
