Hey, here is the formula for the lineair weighted equation. Weighting based on testing time, with the weight of indepentent results being time/avg testing time (16.3hr at moment of writing)
Code:
Vcore=0,28153*freq-17,50661

(Frequency in MHz)


Based Weighted Least Squares using Macrobundle, http://www.bowdoin.edu/~rdelevie/excellaneous/#downloads, the WSL1 macro.
Code:
Coeff:       -17,50661206    0,281534063
StDev:  167,3160494     0,03659375
Sf:     55,62867207     
CM:     27994,66038     -6,118960445
        -6,118960445    0,001339103

More info on weighted results and the macro's can be fount in this excel document:
http://dahorner.faculty.noctrl.edu/Excel/weighted_least_squares_example.xls
Please just use this as reference and estimates...

Also this equation is linear, and I doubt the voltages actually square linear. So I'll repeat myself and just take these numbers as guidelines or reference to rate your CPU.

Unweighted plot and trendline:

So, a little update. After several successful 4.4 stability runs @ 1.168, I bumped the multi to 45 and now P95, IBT, and Cinebench appear to be crashing a few seconds into the tests. I'm assuming that I've reached the limit of 4.4 on 1.168v but why no BSOD or lockups? Is this common activity for just out of stable range with Ivy?

if 4.4ghz is stable with 1.168V vcore, and you only up the multi to 45,
it only means you have to up vcore also to make 4.5ghz stable,
you have to find a new vcore to make 4.5ghz stable again,
you need to up it till you can run cinebench, prime and ibt again,
the first limit you prolly run into would be temperature getting to high running IBT or prime

you havent reached any limit yet, you only found the vcore that makes 4.4ghz stable,
its not always that you get a BSOD first, then lockup , then programs crash,
it can be in any order, just means your oc isnt stable, whatever happens/comes first smile.gif

(evil laugh)...hehehe...

10.28 points at 5.1ghz wink.gif


used xmp profile for ram this time(9-9-9-24), and adjusted blck a bit(100.20) ..thnks biggrin.gif
o, used 1.610V vcore this time, to make sure Cinebench would run the first time..lol

I knew you could do it VonDutch!!! You were just a tweek away!!! Great job number three!!! thumb.gif

I'll play around with ram timings and see if I can get alittle more out of it. And its all fun I love this sort of thing.

Well, the heat is on kgtuning - you did notice that VonDutch did it!!! Maybe no way you could ever catch that 5.1 score of his!!!! hehehe biggrin.gif

Not sure if you still have headroom on the memory, testing kits yesterday I could jump the cinebench score up by .7 just tightening timings at the same clocks.

Good luck!
