350Mhz Max FSB for Q6600 on Asus P5N32-E SLI Plus?

[obeseotron]

I picked up a Q6600 last week and I'm having some trouble getting it up over about 350Mhz on the FSB regardless of multiplier. 9x350 for 3150Mhz seems to be totally stable but it gets very dicey beyond that and 360 won't even get through post. I thought it might just be the limit of my CPU, but 360x8 for 2880Mhz doesn't get through post either. Is this just the limit of this motherboard or am I missing something? Settings below:


BIOS 0803
vcore 1.40
1.2v htt 1.35
sb 1.5
nb 1.40

ram: 5-5-5-12-2t 2.0v running at 800Mhz Async

Cooling?

 

[obeseotron]

Thermalright Ultra 120 Extreme w/ 1200rpm fan. Temps are roughly 37C idle, 48C dual core load, 56C quad core load.

Wait for a BIOS update, the board still has trouble with quads according to the XS thread on it. That AT article that came out a week or so was saying that all the 680i/650i boards are getting BIOS updated now/soon for better 1333FSB and Quad support.

I have the eVGA NF68-A1 and I hit the wall at (450fsb). It doesn't matter what multiplier I use, it just will post at all. The funny thing is, I've tried 487fsb and it boot, but two of the cores are disabled. Really weird. I was hoping I could run it at 450x8 for 3.6ghz so that my ram will be at 900mhz at 4:4:4:10:1T.

There are still some Nvidia based boards that do not overclock well with a quad regardless of the BIOS used. There was a design change to the boards at one point. This is why EVGA markets so many different 680i boards.

Thanks for the link, looks like what I'm seeing isn't out of the ordinary. Hopefully the BIOS update will help things a little bit. I mean with stock quads now using 333fsb, it's hard to believe nVidia is selling boards that can just barely do 5% better than that, even with upped voltages and such.

Q6600 is 1066 FSB stock. 266x9 = 2.4Ghz

You didn't know that Intel is selling quads with a stock 333 Mhz FSB/ 1333 Intel "FSB"? Here's the newegg link, in case you decide you want one: link.

Look at the Q6600

Don't show me what is not discussed

becides...anyone spending $1200 on a CPU is not a smart shopper anyway

I was actually discussing the QX6800 in that comment. 1333FSB support is in big letters on the box the board comes in as well. My point was that I was surprised there was so little headroom in the board considering that it is promoted this way, I fully understand my chip is 1066 (266), and that the QX chips are a terrible value.
