LCBQE/LCB9E 3GHz limit?

post #1 of 15
Thread Starter 
Has anyone hit 3GHz+ with their LCBQE/LCB9E's? I've hit a wall at 330FSB (2970MHz, unstable suicide at 1.4v), but it may have been the limit of this PSU for the Northbridge voltage.... Or the motherboard FSB MAX...

I have an LCB9E. I run it 3003 mhz (273x11) 24/7. Max overclocks are in sig.

I have an Opty 170 LCBQE I'm currently testing right now at 285 x 10 at stock volts with excellent load temps under a XP120. I'll let Ortho's run over night at this setting, if it's stable I'll bump up tomorrow and test again. I'll post back in your thread my results. Good luck with yours hope you can get the magic 3.0!!!!!

SORRY TO DOUBLE POST!

If anything I'd bet it's your mobo fsb max. Can you increase the chipset voltage a bit to see if it get's you any farther? BTW I wouldn't consider 1.4v suicide that's a low voltage for that processor. You'll be safe up to 1.55v or so as long as your cpu cooling is sufficient.


BTW check this thread out for different Opteron steppings, Overclock results, temps and volts.

I've tried 1.65v... nothing. To up the northbridge voltage, I need to voltmod. I'm waiting for the OCZ PSU to do it with. I want stability.

So do you have a new PSU coming or are you talking about the one in your sig? How difficult of a volt mod is it? Are we talking about a conductive pen or a soldering adventure?

The one in my sig is the one in the mail. the CR-450B is what I'm using now, but I changed my sig for the OCZ.

I can't hold very still.. I'm not sure yet. I have yet to look it up. I have a micro potentiometer in my desk... 100k-Ohm

Hey man, Just wondering what was up? Did you get your PSU yet? I hope it solves your problem, being so close to 3.0 would drive me nuts.

Power supply wasn't the cause. Here's my max for now:
