4.3GHz is stable using auto VCC and about 75% vDroop. 4.4GHz is stable it seems also using auto VCC and full VDroop, but temperatures are an issue for me.

I'm runniing on air. I'm using a Gelid GX7 cooler. The case is very well ventilated but I'm hitting mid to upper eighties on the central CPU cores when the CPU is being fed about 1.270V on auto according to CPU-Z. My experience of using this board is that you'd have to set VCC to significantly higher than 1.270 in the BIOS to actually have a CPU-Z display of 1.270V. Reduced PLL from 1.8V to 1.55V but it made no difference to temperatures; or certainly nothing that changed the game.

My question is do these temperatures sound normal, or does my mount sound as though it might be bad? When I mounted I used a very small amount of TIM, in hindsight less than I intended to use. Cores 1 and 4 will usually be running about 7-8degrees cooler than cores 2 and 3.

New review (dated today) of this board over at Anandtech, for anyone that might be interested in reading it.

Your temps are pretty go on air if your at 1.27 volts. thats really high for 4.4 ghz. I run that for 4.6 im on custom water and im dellided and my temps are in the mid 70s weith IBT max stress setting. My temps are high for a delid tho because im waiting on my liquid ultra in the mail so i have AS5 on the die for now. So in hsort no your temps arn't to high if your stressing with ibt or prime 95. I would set droop to 100% tho and do a manual voltage setting. It shouldn't have to go to 1.27 for 4.4 ghz

Guys, what's the thing with offset overclocking not possible on the mpower? Is it really viable? I mean, being able to not set a constant voltage for the cpu sounds quite tempting.

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."

Couldn't dig through and find the original post but do you mean this method?

Actually I just read through this and one thing I have to ask is I can only change my voltages and cpu ratio through click bios it won't let me change it in the actual bios. Anyone know why?

I'll try again with manual, but the last time I tried (and I'm fairly sure I was at 100% VDroop), my failed 4.4GHz was getting about 1.255-1.260, so I think auto seems to be pretty accurate for my chip. Similarly the voltage it supplies for 4.3GHz seems to be around where it was when I tried manual. I don't know if there's some magical setting that I've missed that somehow makes everything wonderful, but I can't see any way this chip will do 4.4GHz lower. Using auto for 4.5Ghz blue-screened as windows booted and I didn't try that again; but as I say, temperatures are the issue so even if auto could do 4.5, it would still be too hot.

I'm talking about getting an overclock that doesn't spit out any WHEA errors in event viewer. If I only went on what prime says I'd be running 4.5GHz at about 1.17V and still increasing the speed, because Prime has never given an error, even for the most ridiculously undervolted overclocks I've tried. They had a log full of WHEA errors in event viewer, but not a single fault in prime although some weren't tested for long though. Once I saw all the viewer errors I canceled the tests and changed the settings.

I contacted MSI technical support and they were unable to explain what changes may have changed the over clocking ability of the BCLK between the BIOS updates. doh.gif


I just figured out the change.

In over clocking settings in the past I always left the cpu mulitplier set in OS enabled. Before 17.6 no problems. So now I disable that and I am able over clock BCLK from BIOS again. I don't use the Window Over clock utility.

Proof.

Just found out that I had "Overspeed Protection" enabled in the BIOS. Don't really know if that would make a difference between a stable overclock and one that throws WHEA errors in the sense of whether having that enabled would actually cause the errors to happen but I'm giving 4.4 another go using 1.27V in the BIOS (CPU-Z reports 1.256V). If that's successful I'll try 4.5 using the same voltage.

If any of this works, whilst I've got a little bit of room for wiggle on the voltage, it's more about how high I can push the multiplier without altering the voltage much. Annoyingly, using the "large FFT" setting in prime, it's only the second test (or pass probably) that generates the temperatures in the 80's. At the moment the temps are low 70's on the hot cores, and high 60's on the outside cores.

Which tab in the BIOS are you trying to set things under?

I think I found that I couldn't alter the voltages under the "OC Genie" tab until I had changed the "My OC genie" option to customize I *think* that then allowed certain things to be edited.

If you are overclocking in the "standard" however tab then I'm afraid I don't know.
