What batch are you on?

A side note, it seems my cpu is unstable after 50+ BCKL. if i said it in 51 i have to give to much core in the cpu to be stable. But if i set my BCKL to 50 and multiplier to 102.1 to get 5.1ghz it runs stable at much less voltage. I have learn that if even you have a high BCKL and can boot to windows, it doesn mean you can get it stable.

You're getting your BCLK and multiplier mixed up. But 5 GHz at 1.45v is very good with HT on. Make sure it's stable - so run Prime95 in blend mode.

i now switch to 5.2ghz ht off because i get smoother gameplay in my games with ht off. I'm not talking about higher FPS just is that the movement of the screen is more buttery smoother without it. 5.2ghz 1.48v i have to update my sig but would like to prime blend alot longer.

Here's my Blend 1hr test for you.

It took a small increase in Vcore over what small fft's needed. 1.450v failed and 1.475v passed.

The true test for these CPU's is proving to be Blend, not small FFT. Drop the small FFT requirement for 2 hours of Blend instead, or even just 1 hour as it is now. People have been running small FFT for 4 hours with no errors, then crashing within 10 minutes in Blend and games.

I'm leaving it the way it is because of two reasons.

1. I have already changed the rules around so much in the last month that members were getting agitated and I don't want to upset the masses.

2. With the current rules setup, blend IS included, and unless you have screenies of both, you don't get in. So it still blasts those unstable oc's to the voltage needed to be "TRULY" stable, and I post the highest vcore of the two screen shots.

I no longer have my board or cpu - I've RMA'ed both. The board was RMA'ed because I want to get the sata 2 fix done quickly, and I also RMA'ed my chip in the hope of a slightly better one.


Wish me luck
