Q9550 on a 680i

[Brock123]

Before I ordered I couldn't find to much info other then people saying it shouldn't work and a few saying that their friend's worked fine. So I figured I would post for those wondering.

My mother board is an EVGA 680i N63 so it is even the crappy 680i.

I am able to oc it to 3.347. My goal was to get the fsb to 400 but I didn't quite make it and had to stop at 394. Far from a huge over clock but plenty L4D and WAW only use around 50% of my cpu now compared to maxing out me e6600. My system seems pretty stable I haven't had it crash in the 2 days with my current setting.

Screen shots are easier then typing a ton.

I think I managed to get it stable at fsb 407. I just ran prime95 for about 40 min.

nice dude. i have an XFX 680i LT that i managed to get my e5200 to 3.2ghz on. 680i is a horrible board for OCing core 2 based chips on, thats for sure. i havent tried it yet, but eventually i want to drop my e5200 into my UD3P and see how high it can really go. the 680i has a bad SATA port on it and it's flashed to an evga 680i bios (probably the same as your boards) because the vdroop with the xfx bios was so bad it was making it dangerously high at 3.4ghz. i had to kick it back to 3.2 but it's been fine since lol. i wouldnt dare put my q9650 in there

What I find absolutely astounding is that you got a penryn quad to work on a 680i at all...My understanding was that if you wanted a 45nm quad you had to upgrade to the nforce 7 series. Did they recently change this with another bios update for the board?

Anyways, good quad OC for the 680i! Makes we want to play with the OC on my Q6600 and my 780i FTW a bit more...mb see if I can get it stable above 3.4 GHz. Right now I have it set to just 3 Ghz.

Also, I do believe that my old 680i LT did do an ok job of ocing the old e6320 I had, from 1.86 to 2.4 about, which was a good increase at the time and on stock cooling.

No its not suppose to work but I figured I would try if it didn't I have a p35 I could put it in. But I can't get nearly as good of ram timings on the p35. I did have to back down to fsb of 394. I crashed playing WAW at 407. So I couldn't quite get my 400 fsb.

i should mention that shmee and i are talking about the exact same board. we have a habit of buying and trading parts off each other lol. his q6600 lived in this board for a while as well

I actually have an evga 680i and popped in a Q9400 2 weeks ago and it actually worked for me too. I didn't try overclocking though, but from what I've read on the evga forums, these 45nm cpu's aren't supposed to work..or that's what everyone is saying. I guess we're the lucky few that are able to use these.

Just recently upgraded to a 790i now...

The main issue I read about was that it would end up defaulting the multiplier to 6x because it didn't properly recognize the CPU. Maybe it's a non-issue if you overclock and disable speedstep?

 

[Brock123]

I use speedstep and it works fine. Maybe the p33 bios are better then the p32. Most info that I found was on the p32 bios.
