ASUS P5N32-SLI 680i Owners - Need your OC Profiles/Numbers

So I tried many custom settings that I read online for the P5N, and almost all of them froze the computer, and it wouldn't POST. I got it to 3.0GHZ and saw just the POST screen. I was wondering if you guys could share some overvoltage numbers and see how I can get close to the 1:1 ratio.

I have a:
1. Q6600 with G0 Stepping (MX-2 Thermal Application)
2. 4GB Patriot Extreme 6400 4-4-4-12 that's supposedly Micron D9 and has a lot of OC potential
3. ASUS P5N32-SLI Board (Rev. 1302 Bios 11/05/2007)
4. Zalman 9700
5. OCZ Memory Cooler with 2 Fans (and then 2 120mm fans in my case)
6. 2 x EVGA 8800GT KO SLI (675/1950)

Ram voltage for Patriots is at the recommended 2.2v (I know, I know)

The only thing that runs stable for me is the auto AI overclock at 15% with 5-5-5-15 timings... and that's a paltry 2.76ghz (306.51 X 9)

I've heard the Q6600 can go to 3.4ghz with this board, and even 3.2 on stock air. Please help!

PS: My northbridge fan should be coming soon to cool down this hot/unstable board.

The temps you are seeing is the Zalman at 40% with the AI Overclock at 15%




I'll probably need to know:

1. Did you change the multiplier from 9x? Or did you just raise FSB
2. Are your settings Unliked/Linked/Auto?
3. Did you disable the PCI-E spectrum? I heard the Asus mobo autoclocks the PCI Express lanes
4. Your voltages (cpu, nb, sb if possible)
5. Anything you changed!

I really, really appreciate this! =)

try and setup the FSB to be 1333 so you are at 3ghz, set the ram voltage to 2.0v in the bios and the cpu voltage to 1.3. Make sure to unlink your FSB and ram speed and under the Nvidia ram overclocker to manual and see what you get. Here is a link to a thread on another forums all about this board:

I tried 1333 even with ram at 800 but I'd get a POST freeze. I do not know how some are getting 3.4ghz on this board with no vcore change and 4448 2t timings. I just need this to hit 355 Fsb qdr with a 9x multiplier. Today marks the end of my rma refund day too with newegg open box

I got 3Ghz on this board with my E6600 without even trying. However, I don't think it's the best board for overclocking quads from what I hear.

citizen__erased:

Did you set your FSB (QDR) to 1333 and unlink the Ram to 800mhz?

Right now I'm somewhere like 1278 FSB and 920 mhz--if I try conventional ways like I've read online, the system won't POST.

I'm at 2.88ghz now with the VCore at 1.4 and memory at 2.2v (Patriot Extreme recommended voltage)

Yep, I just set the FSB to 1333 and unlinked the RAM. The only other thing I did was manually set the vcore to its stock value of 1.325. Shame that if I want to go up to 3.2Ghz I have to really ramp up the vcore. So I just leave it at 3Ghz.

Hmm, I'm wondering if 1.4v for the CPU Core for a Q6600 is a little too much... since I'm only hitting 2.86-2.88ghz anyway.

So, I tried my settings in:

1. Orthos: Failed a test within 6 minutes, everytime
2. Everest Benchmark: failed test 30 minutes in
3. Counterstrike: 1st few attempts resulted in crash
4. Team Fortress 2: some stutters at 180fps 1920*1200, fails every hour, nvlddmkm errors all over the place--Game is made unplayble

QDR FSB: 1274
Ram MHZ: 930

Ratio: 11:16

I cannot do standard unlinking and leaving the memory at 800mhz. The only things I've changed are the voltages (tried auto, 1.325, 1.4), and added a northbridge cooler, which is an active cooler master 40mm chipset fan.

I can conclude that this motherboard is the least reliable and least overclocker friendly mobo I have used. No more ASUS open boxes, even if I save a measly $60.
