4.4? On air? I might get the Q9550 to do that, but not for very long. That's deep into suicide run voltages. Still,

I had to back off 4.25 for now because I couldn't get it stable. I'm going to give it another shot later. But 4GHz looks like it's going to be good for 24x7 folding.

Some questions though: How high should CPU PLL be? When on Auto, the board seems to be pushing it to 1.75V or even higher. How much voltage can I give the NB? And the perennial question, how can I give my CPU more volts without cooking it like an egg?

I just put my e0 9550 on the board (well my second board, I bought another one). I'm going to do some testing with it and my Q9650 over the next week.

What are the northbridge temps at 500+ FSBs on this board? Presumably the chipset and MOSFETs are aircooled even if the CPU and GPU are water cooled.

Awesome thanks.

Nice results. I have an E7300 in my kids rig. Great chip

Welcome to OCN btw.

Please go into User CP and fill out your system specs.

kaxel · 12-08-08

I've only been able to get my e7300 up to about 3.4 ghz stable on the ud3r with voltages nearly identical to yours. Do you have any ideas as to what the problem might be? nice temps, what do you use for cooling?

I updated my sig specs but I use the Vigor Monsoon III LT

I am far from being a good OCer and I found my OC simple on this board. I do have a question about how memory speed and divider effect the bandwidth. I can change my OC to 400x9 same 3.6Ghz and although I cant get my RAM to run at 1200 like with the 10 multiplier, at 1066 my Read/Write/Copy all go up over 8500 and latency drops to 58ns. So my question is which is better, my logic says the later but is this correct?
