Do I have a crappy PhII 1055t?

post #1 of 5
Thread Starter 
Got me a 1055t today. Popped it in and naturally started overclocking the thing.

I can't even attain 3.64GHz at 1.5V. I've disabled virtualization mode, turbo core, C1E, ACC (though I've tried using ACC), and CnQ. I reduced the HT link and NB speeds to below 2GHz, so that shouldn't be an issue. RAM is running well below stock and at very relaxed latencies. I tried using 13, 13.5, and 14 multipliers, to no avail.

I read about disabling PCIe spread spectrum, but I can't find an option for that in my BIOS. Could not find an option for LLC. So, am I doing something wrong? Or is the chip a crappy OC'er?

Stepping is CCBBE CB 1034MPMW if anyone's interested. Google returns nothing but one result for this stepping.

Make your ram Stock, make ht 2000 MHz, make CPUnb 2200mhz to start out (stock is 2ghz) then make CPUv 1.45 with llc on. Then also make cpunbv 1.25. Respond if it is stable. Then we will work from there.

Why would I do that? I'm just trying to find the max core speed by isolating every other component. At any rate it's stable at completely stock settings.

I can get to 3.58ghz at 1.45 before it fails linx. As stated in the op, I can't find an option for llc.

It might be a weak NB multiplier; try a different one. I had problems with x7 and x8 on my mobo until BIOS F8F.

Does that apply even for NB multis that result in a clock below 2GHz? Stupid question, but I just wanted to make sure. It certainly fits the symptoms... I've never gone beyond 1.175v for any of my overclocks before, but I had to crank to 1.25v to get stable.

Will try again later. Thanks.
