srry using my phone but...

nvidia sli requires a bandwidth of 8x or more to function in sli the badwidth goes like this acording to motherboard pins in the back.

16x,0x,0x
8x,8x,0x
8x,4x,4x
8x,0x,4x

the bottom slot can only use up to 4x not any more ,sli requires 8x or more like i said Xfire can function at 4x but sli cant.so this motherboard is a no go infact i dont know any z77 motherboard that will do what you want with those graphics cards. srry but you will need to go either z77 with a plx chip or x79

What sort of errors do you get when you lower PLL too much? BSOD? WHEA errors?

I don't remember now for sure think a whea couple times

Put a real low number see what it does, Maybe a no boot into windows

I usually leave cpu pll not on auto and set it around 1.60-1.70 to start

How to OC your Mpower for everyday use

Due to the amount of people having issues with setting up a 24/7 OC Im writing this mini-guide to setting up your Mpower so you can have a moderate overclock while still maintaining speedstep and idle voltages instead of it running at a set voltage 24/7. I'll be showing you pictures of my settings via Click Bios 2, I am only showing you them this way because its easier than taking screenshots in the bios while I write this, I do not advocate using clickbios to enter these settings. I think all adjustments should be made in the bios directly.

Oc Tab


Leave CPU ratio on Auto, dont worry we will get to that in a minute.



Leave CPU Core Voltage on Auto you can set DRAM, PLL and whatever else you want but I just adjust those mainly because I noticed the board will use a little more dram voltage than what x.m.p. specifies and my cpu doest require that much PLL, as always YMMV.

CPU Features Sub Menu


Make sure you leave C1E Support, Intel C-State Enabled and set the Package C State limit to Auto



Now here is where you will input your desired OC, I use 45 your chip might not be able to do it but it could be a good starting point. Input the value in each slot.

Now here is where everyone was having issues, remember when I told you to leave your CPU Core voltage on AUTO? Here is how you make your voltage adjustments.

Hybrid Digital Power Sub Menu


Make your adjustment with just CPU Core Vdroop Offset Control. My chip needs a setting of +62.5% to be stable at 4.5ghz, YMMV. This equates to a realworld load voltage of 1.240v tested through a multimeter (seen here) with no huge spikes or anything like that. I dont know if thats the exact value all boards will give at 62.5% offset but I dont think it would vary by much. To start though if your going for 4.5ghz I would set it at 50%, boot into windows and run cpu-z and load up prime95 and do small FFT's for awhile. The 50% value for me would have 2 cores fail after a couple hours but it would start throwing WHEA errors in minutes. 62.5% is the sweet spot for 4.5 for me, 4.6ghz is stable with 80% offset but I'm happier with the temps on 62.5%(under 70c during stress on prime95). I do recommend turning the digital compensation level to High and the CPU Core OCP Expander to Enhanced to help with overclocking. All the other settings can be left on Auto, also I recommend leaving the CPU Phase control on Auto as well, why make them work when they dont need to? It hasnt affected my stability at all during the time I've been running it like this(since the board released pretty much).

Ok so that wraps it up, go ahead and give it a try and see what you get. As always YMMV, every chip is different and could require more or less voltage to get to a desired OC. In the absence of not having an Offset this is the next best thing. Hope this helps.
Bios used during the writeup was 17.6 Beta 2 found at the link in my Sig.

I'm curious, how safe a method is this for overclocking? I'm currently using this method for a stable 4.2GHz, but my CPU Core vDroop Offset is on default. I really like the idea of a 4.5GHz overclock and being able to keep the power saving futures, but have been scared by my research of LLC and the longevity of my 3570K. I need it to last me a while. Thanks in advance!

I posted a video of me testing it with a multimeter here.

Your 3570k may have issues going to 4.5 this way, Auto CPU Volts YMMV

Nagels using a 3770K Chip.

Mine, 3570K goes to 4.3 this way but no higher unless fixed cpu voltage and 100% vdroop
It does work well for Auto Volts max 4.3mhz here YMMV

AND NO WHEA errors in administrative logs

I don't seem to have low write speeds like you do, but I'd like to get as much performance out of my new drive as possible.

Anyone know if the Intel driver is supposed to increase speeds by that much if I'm just using a single SSD with my OS installed on it? I went to go download the latest version from Intel's site, but it said I needed to have already installed an F6 BIOS setting or something, so I didn't bother.

I just picked up a pair of 840 Pros last night (128gb) to stripe and wanted to do the firmware update running into the same issue. Good timing, I'll try to fix it tonight.

You're right. Just tried it and would BSOD when starting Prime95 at both 50% and 62.5% CPU Core vDroop Offset. Stable at 4.3 like you though. So there is absolutely NO way to get down-clocking and down-volting at idle when setting vcore and multiplier manually?

No but with v droop enabled(100%) and manual voltage these units do (are supposed to) use less power
