Yep, I have two 4870x2's in mine.

Here is my build log:

quick question, how to covert mV to V ? example:
the defult CPU VTT is 1.1v = +0mV .

[Fitseries3]

+50mv would be 1.15v
+100mv is 1.2v

and etc

[Splave]

1mv = .001v
100mv = .1v

[quattro_]

gotcha, thanks for the fast reply .

[quattro_]

1mv = .001v
100mv = .1v

now im lost again then why is 1.1v = +0mV ??

The default CPU VTT is not 1.1, its 1.2. I`m using for 24/7 +0V = 1.2 measured with DMM and + 0.05 = 1.25, + 0.075 = 1.275, +0.1 = 1.3 ...
The default just cant be 1.1 because of the diffrence between VTT and memory voltage if its 1.1 it ll be 0.55 when memory is running at the default 1.65V, but higher diffrence than 0.5 can kill the CPU.

[Splave]

say your stock is 1.2, the way it works is you add to the original number.
100mv = .1v so if you set +100mv in the bios you get 1.3v


+100mv = +.1v
.1v + 1.2v = 1.3v

[quattro_]

good enough thanks again

hard one for easy question.....

What B2B settings are you guys using? I've heard 4 is best if you can pull it off?

Yep.

I`m using 3, cant see any diffrence if I leave it auto, havent tried 4.

BTW I checked CPU tweaker 1.2 and it shows me B2B = 4.

[Splave]

Im using 4 atm, everest read and aq3 seem to really like it so far

[cheapseats]

on s61a (and b ?) need to set B2B 3 in BIOS to get 4 in cputweaker.. bandwidth and 32M suggest cputweaker is showing correct value for B2B.

BIOS set 4 (tweaker 5) is slower than Auto/disabled/0 at clocks i tried.

Is it best to leave Vdroop enabled with the EVGA boards? I have read arguments from both sides, it seems better to leave it on and add the little extra Vcore to the CPU to supply power under load, although I could be wrong. Will the voltage spikes with it off ruin any equipment or will the power supply system of the Classified be able to handle those spikes?

Nah, VDroop is not good for OCing IMO.
Can only ruin your PWM if it's crappily built, but with 10 phase digital PWM you're absolutely fine.

[The_Game]

Never tried turning Vdroop on lol. Its not DFI, where if u leave it on and the PWM cant be cooled on air. I`m using 1.4V BIOS measured 1.39 idle, and 1.41 load Without Vdroop and the PWM temp was max 50-55 during the hottest summer days.

The newer BIOS' (61A & B) play a lot nicer with 12GB of RAM than the previous BIOS'. Previous 100% stable OC was 4.24GHz, now 4.5GHz (215x21 set in BIOS, not ELEET).

to the forums!
And that's very nice low vCore for 4.5Ghz!
Care to post your settings?

I am having some major problems trying to get the classified stable past 4.1Ghz, now I think it might be a problem with the new memory I had just got, the HyperX 2000mhz cas 9 kit, with the BBSE elipisa (spellINg?) based chips. Now I never ran my uncore at 4000mhz before, what kind of Vtt voltage will I be looking at in order to keep the system stable. I am trying to run my RAM around 1000mhz or more, and my Uncore will be a min of 4k mhz, any ideas, I tried Vtt of about 1.500v and I get green screens and system hangs with even a high 1.40 Vcore, which is what I need for 4.4ghz on my UD5, not 4.2, I only need 1.344V Vcore on my Ud5 I would think the classified would shave some off and maybe give a lower voltage. I am okay in linx with a 2:6 memory divider, but 2:10 is all ted up on me. I would like to try and see what my new RAM kit can handle so I want to push it, my memory timings are also loose at 9-9-9-24 1t. Any ideas? The classified is taking some time, a learning curve I would say options I never had before, but also some options less than the UD5, now is there a HPET option on the classified? I dont see one.

The new s61B Bios, I think those are the newest ones...And updating the BIOS with a USB drive is a job compared to the ud5, which was like a hot knife through butter it was so easy.

I am just not used to the settings and options the board has this is my 1st time really sitting and trying to OC it. Now the MCH strap I have on auto, since there is no memory controller on the IOH, so what does this control now, the MC in the i7? I also have the 3 PLL voltages on auto I will check the rest of my settings.

[Splave]

try increasing the qpi/pll a bit?

[Jakethesnake011]

What would be a good increase on such? 50 mV? Or more, I never had a QPI PLL on the UD5 I was using.

[Capper5016]

Jake, take my template and fillout your settings. I'll be around all night and would be happy to help anyway I can.
