I don't own a Neo2 anymore, although I wish I did. IMO it is THE best s939 AGP board out there. It is good to hear there is some dividers available in the BIOS now too, lol.
Anyway, if you mess with the different CPU voltage settings, you are sure to find a combo that puts it right where you want it. And I measured the vcore directly off of the board with a mm - I don't usually trust apps for that sort of thing when pushing 1.7+ volts into a 90nm or 65nm CPU.
It is also my experience that Ntune should only be used in case of emergency, if all else fails. I have had nothing but problems with that stupid program and I wouldn't touch it again with your PC if I had the choice. If you've got clockgen, A64 Info, and Core Center, you can rule the world.

question regarding CPU temps and latest bios (1.8)

I'd believe the first bios's temps more than the second...
However what temps are given when using speed fan and/or everest? (in windows)

cannot change CPU Voltage??(first time here)

In Cell Menu you will find something like CPU VID / Over VID. The first will be set to Startup (=you CPU default volts) and the 2nd will be disabled but you can set them manually to CPU VID = 1.4 and OverVID to 3.3% / 5% etc to let the CPU use higher volts when Oc'd. Good luck !

MOVED: Problem with CPU Voltage

I have similar issues, it's hard to tell which measurement is the most accurate, there are 2 different measurements in the control center that don't match up with the figures set in the bios. The only way to be sure would be to get an expensive accurate multimeter but If you're only interested in running a stable overclocked computer without knowing the exact figures then get the computer running stable and lower the voltages until it starts to become unstable with prime95,
Or you could work the other way round, set the voltages so it boots but doesn't run prime95 for long, then raise the vcore and vtt one at a time until your happy with the length of time prime95 runs without errors. I'd be happy with 24 hours, I seem to remember errors creeping in at around the 9 hour mark on the setting below what I have it set to now.

Please provide more information for the rest of your system. >> Posting Guide <<
You are using +/- keys on numpad & not +/- next to 'Backspace' key ?
You should be able to get way over 1.2V, look at his thread: http://www.testseek.com/labs/reviews/review-of-msi-nf750-g55-motherboard/?p=2740

How to get higher cpu voltage during load when using "auto" with P67A-GD55?

I have a little question regarding cpu voltage: When i set vcore to "auto" i get a nice low voltage when idle but during load i only get 1.264 max and that is to low.
Is there a setting to increase the voltage during load and still have the cpu vcore set to auto?
Thanks
System:
P67A-GD55 with 1.8 bios

OK, so you are able to set your CPU voltage manually. You need to consider that the auto voltages will compensate only up to a certain OC level, after which the user usually has to do manual adjustments. This auto compensation differs for each hardware combination. As HU16E suggested, try low VDroop and see if it helps. The other alternative is a BIOS flash, or manual voltage settings.
I tried low vdroop but it didn´t make any difference. But it´s ok, i can set the vcore manually but i was just investigating if i could get the best of both worlds with the powersavings auto vcore offers during idle

[915 Series] CPU Voltage and clock multiplier

The manueal of 915G combo says(page 3-24):
Adjust CPU Voltage
The settings are used to adjust the CPU clock multiplier(ratio) and CPU core voltage....
I dont know how, and you?
Can anyone explain that to me, please.
cheers

If the value has a "v" or "X.XX", it'll be the value for setting the CPU voltage as Mutiplier settings only comes in full numeric value like 1, 2, 3, 4... 20 etc.
My guess of why it is being phrased as such is mainly to due the different settings to o/c a system may require a minor increase of the CPU Voltage to keep the whole system to run stablely.

785G-E53 (DDR3) - Is CPU Voltage configurable ? (presale question)

Hi,
i'm searching for the board which fits my needs, 785G-E53 looks like it (even if it does have 1 less SATA port due eSATA which i don't need), but since this is going to be a low power machine with Sempron 140 then CPU voltage adjustment is a must (on current board this Sempron 140 runs with 1.05V Vcore).
Because manual is not entirely clear on this, i would like to see a confirmation from MSI or someone who owns this board that this boards allows you to change CPU Voltage.
Thanks

You also need to take into consideration the low cost $50-$80 micro ATX MB's seldom have the BIOS features their full size more expensive brothers do.
The BIOS features of both boards were pretty much comparable (it was GA-M85M-US2H (rev. 1.1), price in USD converted from EUR is close to $90), i account the difference to chipset, RAM module difference (1xDDR2 vs 3xDDR3) and different VRM.

Lowering the processor speed, in MHz, will also lower power consumption. Performance will drop, too.
Another thing to consider is the PSU itself. 75% or 85% efficiency will amount to quite a lot. Normally PSU:s are configured for a certain level of demand, for example 100W. If you find a PSU specialising in low power consumption you will save a little more. I have had good experiences with Nexus PSU:s in that respect.
Lowering MHz does lower the power consumption, but not as much as lowering Vcore, and with 5 hard drives 61W is a extremly good result IMHO. PSU is not a issue here, that computer uses my spare Corsair HX520. Unfortunately i had two Enermax Modu82-425 going to RMA, so i don't really trust Enermax anymore even if the issues were rather small (clicking fan noise in 2nd case, electric buzz even with PSU turned off to 0 position in 1st case).
The real thing i dislike is the peak power usage when i turn the computer on, it jumps up to 110W (now and before board change too), which makes it impossible to use the picoPSU.

I don't know how to put a image here
I want to rewrite the question. When set to auto my multiplier increases but not as I wish, usually with no load its 7 but sometimes no load is 17 ( just now on line ). when under a load it hangs around 15.5 I like to see it go to 20 and stay. ( now for the first time its overclocking 17 3.4 GHz with no load )
when i go to set it manual it only gives me ( in msi control center ) choices auto 4.0 to 8.5 . wheres the fun choices?
All I need is for it to go from 7 to 20 when i need it and stay low when I do not. without restarting the computer?
Im going to load default in bios now it going crazy . Be back
I had to clear cmos the only default settings where optimized and they made the cpu voltage go crazy like in the koolguy post.
if I can set the multiplier from the desktop without restarting.
Also is it better to set buss speed high or the multiplier ?

P6N SLI CPU voltage options

hi all
I have checked the other P6N SLI posts for this but i was unable to find it. no doubt someone will point me to one but i will ask anyway.
In the cell menu the option for voltage for the CPU is a little confusing to me. My previous asus motherboard had simple voltage settings going up in 0.250v sections, like
1.250v
1.275v
1.300v
they were alot more accurate and smaller but i hope you get my idea.
In my P6N SLI menu, it only gives options like 0.125v and upwards to around 0.300v
I do not get what voltage is what for my CPU. As my CPU is a E6550 its highest voltage is 1.5, how can i know what to select if i were to overclock the thing?
thanks for anyone who understands.
Dan

oh right, so how do i find what my default VID voltage of my CPU is ?
Intel lists it as
VID Voltage Range: 0.85V – 1.5V
You can get the VID by downloading and running Core-Temp. You can leave the CPU voltage at "auto" and the MB will adjust for the correct CPU voltage..you can see approx CPU voltage in bios, under Hardware Monitoring.

CPU Voltage problem...anyone??

hey all, i'm not sure if i have a voltage problem here. should my cpu voltage be at 1.5? it currently runs at 1.35 by default. This is in my Neo4 Platinum board.
Update:
I went to increased the voltage to 1.4 via CPU VID (in bios) however, CPU-Z is showing my voltage as 1.3 which is lower than before. is this correct? Also, watching the voltage readout in CPU-Z i'm noticing the flucuation between 1.36 to 1.408 after setting my CPU VID to 1.4 in bios.. is that ok?
...anyone?

Just using CoreCenter my 12v is a steady 12.14, 5v at 5.05, 3.3 at 3.33 but vcore which should be the steadiest runs between 1.37 and 1.42 with jumps or drops of up to .04. Prior to wed it never made it past 1.39 so maybe it will even itself out at 1.4 +- .02. My other MSI board a KT6V with a 2500 Barton runs a steady 1.63 with a cheaper PSU and a slight oc and the combined price of the 3 is around what I paid for the neo4 board. Maybe I'm expecting to much to think that if you pay more for something the quality should be better.

@home I have a good Volt meter. It cost me more then my mobo. So don't expect the world out the accuricy
Apple that is like comparing apples and oranges there is a big difference in a volt meter which has to handle a large range of voltages and amps and a dedicated chip on a motherboard. The CPU is designed so that at 1.4 volt and a given frequency it gives you a signal strength at the transistor that determines a 1 or 0 bit. "undervolt"only increases the chances of bad data if there is a weak transistor and raising the voltage is only needed if the signal strength drops from the increase in frequency.

MSI P6N SLI-FI cannot adjust cpu voltage

Ok ive tried two different bioses (2.0 and 2.12) and in both I cannot adjust the cpu voltage. It reads 0.00000V and I cannot adjust it please help.

Personally, I think people are jumping to conclusions about OCZ memory . My (MSI SLI Platinum board) system runs perfectly stable with OCZ memory. Saying that OCZ is a problem is too broad a statement - hell, OCZ sells 11 different models of DDR2-800.
The memory in question in this case happens to be the Platinum version (actually, in this thread, the memory doesn't even seem to be the issue), which must have it's voltage oc'd to 2.1v when running at the stated 4-5-4-15 DDR2-800 speed.
Anyway, cell_491, make sure that you've disabled:
C1E (might be hidden on Advanced settings -> CPU Features page... use F4 to show it)
D.O.T
EIST
ALL spread-spectrum settings
...note that these boards will reset to some defaults if you fail to POST a few times, so make sure the above are still disabled. Also, keep in mind that while the memory 'settings' are or can be 'unlinked' from the FSB, it's still using a divider internally, so you might want to clock the memory down to 667 when you're trying to determine the FSB top-end.
I've been running my E6400 at FSB 1333 (333 x 8 = 2.664 GHz) with my OCZ DDR2-667 ram oc'd to DDR2-800 4-5-5-12-24-2T 1.9v (unlinked 400mhz ram freq) perfectly stable for the past few weeks. Last night I played around with oc'ing the CPU some more and managed to get up to around FSB 1480 (370 x 8 = 2.96 GHz) running stable by adding some voltage, but I'm still running the stock Intel heat-sink and the E6400 starts getting pretty hot at that speed, so I backed it back down to 1333 (2.6GHz) which I'm now running in linked mode with my memory at 4-4-4-12-20-1T at 1.9v (I haven't started tuning the timings yet).
I need this board to make my living, so it has to be stable and I can't afford to fry anything, so until I upgrade the cooling, I don't plan to try for something over 3GHz, but if you've got good cooling, then this might help. It's for the 680i chips so the BIOS options will be different, but the 650i uses the same NB as the 680i, so there's a lot of info that should be usefull (including some max recommended safe voltages).

990fxa-gd80v2 cpu voltage stability issues

I have had this board now for 2 mths and have noticed a problem with the cpu voltage. It fluctuates alot ie: set at a voltage it will fluctuate +/- .03-.06 volts. The most significant and generally highest fluctuation is at load where it will drop down usually .05 volts consistently. This greatly affects any adjustments one would make for OC as the maximum voltage for my AMD FX 8350 is 1.55v.
Point being: Is there anything in the works where MSI is addressing this issue. Is there a solution? or is this just a flaw we are meant to accept.
I just want to know that something is being done. I chose MSI for this motherboard because all my previous MoBo ran flawlessly.

It is not looking good. I hope I am wrong but I get the feeling from email response others have gotten that they may be moving on and these issues are a lost cause. Again I HOPE I AM WRONG.
On the plus side I have managed to get 4.6 easily stable and no real issues with the particular setups I use so Guess I can bide my time.

Max safe CPU Voltage?

I am in the middle of OC'ing my system. So far I am doing pretty good. I can get up to 252 clock generator x 9.5X CPU multiplier at 4X HT multiplier. (I currently got my memory at 133 3-6-6-11: I'll tweak this a little bit later.)
To get this I have my CPU Voltage at 1.7V. Running Prime95 with option #2, I can keep my CPU temp below 55C.
My question is, is this voltage too high? I understand that voltage will raise the temperature, and that it will decrease the life expectancy some, but is there some other problem? Is this really safe? Or should I reduce the voltage?https://forum-en.msi.com/images/msi/smilies/confused2.gif

Increasing Vcore increases the gate voltage on the transistors inside which lowers the on resistance allowing the transistors to drive their signal lines harder and thus faster. Increasing Vcore also means the signal lines need to swing farther (voltage wise) than they did before. As you continue to increase Vcore the on resistance of the transistors improves less and less as other limiting factors in the transistor take over, however the signal lines still need to swing more and more as vcore goes up. It's like being able to speed a runner in a race up, but when you do the race also gets longer. At some point the runner is going as fast as he can but the race keeps getting longer so it actually takes him longer to finish.
You want to find that sweet spot where he finishes the race the quickest.
The other problem with increasing Vcore is increasing the temperature of the die because of all the heat generated. The hotter it gets, the more the asphalt melts and the slower the runner will go. You don't want it to get to hot or things slow down.
Increased Vcore also brings a pair of failure mechanisms with it, one is just that the heat can't be removed quickly enough and when the silicon gets hot enough the currents from thermally generated carriers cause a runaway condition and the chip just melts down. This happens fast.
The slow failure mechanism is electromigration, where the currents are so high in the metal interconnect wires on the die that the metal starts to flow. Eventually the wires break. This happens slowly.
Always use the lowest Vcore you can that will give you the performance you want. In other words, err on the low side.
