IMO that BIOS setting could have have been clearer to say something like "allows VID increase with unlocked turbo multi's". With a setting of 0 (Auto?) that means for instance the 2500k VID plateaus after 37x multi. By changing that value to 0.200 then VID will increase to something like 1.5V at the 50x multi. IIRC Intel spec is for 1.52V max VID but it seems to stop at 1.5000V.

I had a closer look at VID. It seems with C3 and/or C6 enabled VID goes a fair bit lower with only one thread loaded. Asus calls disabling C3/C6 an enhancement to overclocking but it seems to me to be a work around for a buggy Sandy Bridge. Would be interesting to hear what an Intel engineer would have to say about it. So with offset which is dependent on VID that would mean using extra voltage or losing the highly efficient power saving of C3/C6. C1E can still be used without C3/C6 to give an idle power of ~12W vs ~5W with C3/C6 or if using fixed voltage then VID doesn't come into the equation and C3/C6 can be used without that problem.

Here's showing the difference with C1E/C3/C6, all other settings the same, EIST disabled and running 45x multi. With C3/C6 enabled the VID seems to be a bit jumpy, whether that's due to the software sampling it idk but you can see the difference in Vcore is quite large. I should also point out that while one thread is tied up like this then C1E isn't going to give any enhanced power saving, i.e. it's just going to act like C1.

My new replacement b3 board needs more volts for 8hr prime stable. bah.

Mine doesn't need more volts, but the calibration is way different.

Using the Additional Turbo Voltage and CPU Voltage Offset example for 48x multi...

Old board: +0.005V offset, +.184 turbo VID
New board: +0.030V offset, +.192 turbo VID

My concern is the settings combined with the new board cause bigger transient spikes in CPU voltage when going from high-load to idle.

Will my current heatsink fit on the new 1155 boards? I found a store that has various P8P67's (B3) in stock and ordered my P8P67 Deluxe along with a 2500K. I get back in here when I start putting it togather, but in the mean tim e i need to know if I have to buy a new cooler? Will my ninja fit socket 1155?

In theory all LGA1156 coolers should fit LGA1155 (they use the same mounting holes), but you should always check the clearance from your motherboard's heatsinks and RAM slots.

Is it this one? If yes, you'll probably need to buy an adapter.

just want to check with u guys

m4e has this issue with ai suite reverting the dram vref to 0.50x as compared to the bios. as long the sensor on ai suite is loaded , values are reverted.

is this the same with all the boards??..

Well my new B3 Asus P8P67 Deluxe arrived a few days ago and for sure does not Overclock the same as the old.

I Just passed a 5 hour run with prime , also a 3 pass with Memtest. Bios 1305.

Thanks for the input, SB is kind of alien to me considering I only OC'd on LGA775 before :clap:

hmm u guys should complain as m4e was given a max power option so users dont have to configure any of the turbo parameters.
just click max power.
dont get it why they didnt give this option to del atleast the one i have been doing for my friend

hmm c-states. i tend to off them completely for initial barage of test to pass
and then final test of stability with them on to adjust pwm frequency etc.

If it does not overclock the same,then how does it?Better or worse :)?

hmm play around with ure dram timings as ure ram is rated for 2k C9 on a p55.
vdim to vdim is about the same on p67 and p55 on dual channel rated rams.
pretty sure ure overvolting because of subtimings

I would say it's a bit worse b/c it needs a bit more voltage on the offset and that gave me a small rise in Temps 5c or so. Also the LLC AND Phase settings have changed from the old b2 , 1305 bios. I could not get stable with my old settings at all. Mabey b/c I was using Corsair Vengeance 8GBCMZ8GX3M2A1600C9 as they run at 1.5v , I don't know mate just my mind is bent at the moment been up all night fooling with this mess.

Don't get me wrong Overclocking this just needs the right mix and I've almost figured it out.:eek:

I've tried so many timings with this ram it's unreal , 2133, 1922, 1866 , 1600, and 1866 @1.62v 8-9-8-24 1t seems to be the best out of them all.. Memtest passed with those settings , If I lower anything it fails. Believe me I put these modules in so many configurations it's mind bending. I wanted to see how good and what all the hype was on the GT. $139 A Set at MC , so I got 2. Now there $169 ,, added AirFlow Pro and that was a bit of a pain as the cables are short and should be done before you have the MB in the case. Also have 1/2 in feser tubing in the way as my dual rez is in the 2nd & 3rd slot FROM THE TOP on the Antec DF-85.. it was a job , but it's done.

so far in sandbridge i noticed this
say example 4750 my 24/7 clocks

vcore is between 1.400 set to 1.420
glops will pass between 79 - 82glops

lower end glops neeeds 1.4
higher end glops needs 1.42

but heck if u have a 5ghz proc that does 1.36-1.4
dont think that 0.02 hurts lol

btw dont follow too much in some of the overclocking guide out there
a lot of speculative and theoretical guide
so far the asus one is the most accurate

Hmm, my G.Skill F3-16000CL9D-8GBRM do DDR3-1866 @1.55V 8-9-8-24-1t as well and they cost $150 right now. They also do DDR3-2133 @ 1.6V 9-11-9-24-2t, which is what I have them set to right now...

The Modules work in all those settings don't get me wrong .. I was just testing with Sandra and AIAD64 Extreme to see what resulted in the best performance out come. As trying to find reviews on these Modules , I had not much luck. Yes I have a 2 sets of G.SKILL Ripjaws X F3-12800CL9D-8GBXL , I been a big fan of G.SKILL as there Trident series preformed outstanding and hooked me on the brand name of G.SKILL and a set of Corsair Vengeance CMZ8GX3M2A1600C9.. I just could not pass up the $139 a set on the DOMINATOR GT's , listed @ $215 on newegg..

And yes I do agree the Overclocking guides out there are not real life down to earth all that true. I had to take a few from here and there and piece them all together when I first started back in Jan/ playing with Little Miss Sandy , now the new B3 board I got you cant use the same settings you used with the old boards well in my case , they just don't work for me.. Needed a bit more on the + Offset Voltage , LLC & Phase Control changes were needed also to keep Prime Stable.

No biggie I just had to take a couple days & nights trying changes , Stress Testing , from scratch pretty much on my own.. Now that I got a stable 4.5GHz and as close to 2000MHz on the Ram I will fiddle a bit more with it but I want to see what the Max is on my Chip & Board.. With my old board the 1st 2 ram slots stopped working and the x16 PCIE slot also.. So I never could have any fun with it..

I just preordered a p8P67 Deluxe from Directron to replace my P8P67 Pro while it gets shipped off to Asus rma

got my Deluxe B3 today in exchange for my gigabyte UD4. liking it much better :up: much more features.

although a bit weird that offset vcore on auto seems to really want to overvolt way over 1.4v for small overclocks even. there should be a +0.000 or "normal" instead of just auto or +/- 0.005 to get normal SVID

Edit: even stranger is -0.005 somehow WAY undervolts the CPU to where it won't even boot, and +0.005 is too much. something doesn't seem right here. that and the BIOS vcore shows much lower than CPU-Z

I hear ya - I've found this frustrating as well. I want - offest to work because of the overvolting, but my box won't boot as soon as I try it. I could rock 4.8-5.0 easily, but won't because of the overvolting crap.
Question: If I use manual voltage, won't the CPU ALWAYS use the voltage I set regardless of when it downclocks back to 1600MHz? That kinda defeats the purpose of the power savings/heat savings. That's why I'm kinda stuck using AUTO VCore, no LLC up to 4.6 - anything beyond and it's too much VCore, but yet I still want to use the C-states/EIST stuff.

so it isn't only me...

I'm using manual voltage right now, but I assume if you have EIST/C1E on and such that it won't undervolt. at least that's how it worked on my last gigabyte board. (which btw gigabyte's offset worked fine, why isn't Asus' working right?)

With fixed voltage EIST/C1E will not save you any power however C3/C6 can still be used to save considerably more power than EIST and/or C1E.

that's good to know. but Asus still needs to fix the minus offset. I think it has something to do with the board's BIOS running at only the max reported turbo freq. (3.7 on 2500, 3.8 on 2600) regardless of overclock setting. so the minus offset is probably being based off the 3.7/3.8 SVID. that would also explain the low voltage shown in BIOS. (and you can see current multiplier being 37 or 38 somewhere there)

also, even if C3/C6 saves more power, I would imagine there's still concern for lifespan reduction of the CPU if you're always running a high voltage even in idle. but I could be wrong.

Replaced my board with the revised board and it is quite different with the offsets and voltages. It still OC's well but I'm getting consistant BSOD's (0x9C) with everything at default settings about 10 minutes apart. Runs prime and LinX no problem. Hope I don't have to replace the board again.

I just read 100% of this thread, and still can come to a conclusion for which bios to flash to for my (Soon to be arriving) Sabertooth B3 revision board. I wont know what bios is currently flasshed to it as its not in my hands yet, but what bios is recommended at this point? thanks

another small annoyance about this board is that the CPU fan header will only scale fan speed back with a 4-pin plug supporting PWM. It can't scale back by "voltage" like gigabyte has an option for. but the chassis fans do. although the minimum they can run at is 60%, whereas gigabyte can go as low as 30%. (but it only supported CPU fan speeds, no other fan ports) so I need to go rewire my case now >.< also, I'm still really impressed with the software but the auto-overclocking tool had my CPU up to 1.5v and 1.6v!!! OUCH!!! there should be a way to set an upper limit to voltages or temps, as it had my CPU up to 96c at one point. are they trying to fry peoples chips?

my B3 Deluxe came with the latest 1305 (dated 2/11/2011), I'd assume the sabertooth would too.
