I honestly wish the mobo had manual vcore control.
Well, it does.  You said so yourself:

"Cpu Voltage" it is either Auto (Grey) or increasing the voltage in increments.

I didn't increase it +.303, I was only specifying the limit of what it would allow me to change.
To be honest, I fail to see the problem you are having with the voltage.  That means that either I am terribly misunderstanding what you are trying to say or that you are misunderstanding the way the voltage settings work. 
Can you please try to elaborate what exactly it is you are trying to do with the system?  It is irrelevant at this point, what the system will be used for.  What is of importance is what clock speeds you are trying to run the system with, what exact settings result in an unstable system and which settings have been working for you.  Within a certain clock speed range from the default settings, increasing the core voltage of the processor may not even be necessary.  It all depends on what you are actually aiming for.
In terms of current system settings, you have not really told us much so far:

    I've read the sticky, I know about pg up/pg dn and the +/- keys.
    My problem is that I can't manually set the vcore voltage in the Cell Menu. It says Auto (greyed out) and when I do pgup I can increase the voltage up to about +.303, but it doesn't allow me to manually set the voltage, nor undervolt it.
    I've updated the BIOS to 1.8, but still no luck.
    If anyone has any suggestions, please help.

  • P55M-GD45: VCore cannot be decreased

    Having this strange issue: vcore can only be increased.
    Also strangely when increasing, the next value after "auto" is not the vcore but just the increment amount itself, eg. 0,006 -> 0,012 ...
    So for example under default settings (FSB 133), CPU Specifications says vcore is 1.224V. Then moving down to vcore setting and looking to the right, there is a list with actual, min and max vcore and it says 0.000, 0.000 and the normal value for max respectively. And as mentioned, no way to lower the vcore value.
    At higher FSB, vcore is raised automatically and again no chance to lower it by myself.
    All other voltages are adjustable and shown (on the right side) correctly.
    Any suggestions!? - driving me crazy!
    Thank you!
    P55M-GD45 Bios 1.4

    My i7 rig is with a socket 1156 board, an Asus P7P55D mobo, and an 860 CPU. I know the Corsair DDR3 memory @ its stock 1.65v simply doesn't run at 1600mhz like it says on its box - 1333mhz seems to be its stability wall.
    I upgraded my Q6600 and Asus P5B deluxe rig because so many people said to never consider overclocking on an editing rig. Was that over-cautious advice?

    P55M-GD45 (latest BIOS)
    I noticed after enabling XMP in the BIOS so the memory will run at 7-7-7-24 that the CPU frequency went from 133 to 160 I guess to get 1600 for the memory. I turned the Multiplier down to 17 to get 160X17=2.72ghz for the CPU. When it posted I noticed it said 160X17 2.72Ghz then a couple of lines down it said somethng like "OS SYSTEM 3.2Ghz".
    I ran a few tests and found that with XMP enabled (CPU-Z) I was getting 3.8Ghz on a single core at 100% and 3.2Ghz whan all 4 cores were at 100%. I would get up to 80C and the VCore would hit 1.314.
    With XMP turned off bois set to 133X20=2.66 CPU=Z says 133X21=2.72(four cores at 100% 63C and 1.232 Vcore) and 133X24=3.2(single core 100%)
    Why does the system seem to ignore the multiplier with XMP enabled?
    Can I change settings in the BIOS so the CPU runs closer to 2.66-2.8 with four cores at 100% and the memory timing at 7-7-7-24?

    You cannot overclock individual threads, as these are pretty much virtual entities, not physical cores.
    I meant to say, I wish turbo boost could be adjusted so the freq/multiplier would run at 3.8 on a single thread and 4
    threads would run 2.8.
    I tried several different combinations of XMP and Turbo on and off. In the end I decided XMP off and Turbo on will work best most
    of the time. I think I could have saved $30 and just bought DDR3-1333 memory.

    The I5 chip doesn't have the same memory multiplier as I7, so when you enable XMP for a 1600 profile the BIOS crank up the CPU multiplier to 160 and overclock the CPU heavily - that's the only way the BIOS can get the I5 to due the job!
    There are several ways to get around this, and I have tried to get time to make a tutor about this. For now, just leave the multiplier at 17, or disable turbo mode and set it to 19 or 20, and you are on.
    And - disable the OC in the BIOS, as it really can screw everything up.

  • P55M GD45 experience; only 1.1 bios works, forum usb key boot didn't work, Win 7

    My experience. Got board w/ 1.1 BIOS installed, installed Win 7 64-bit. Used LiveUpdate to flash BIOS to 1.5.
    Then box froze at "Starting Windows" screen. However it would boot ok to Safe Mode, and also Safe Mode with Networking. It wouldn't boot to Knoppix, Ubuntu LiveCD, ... (In Windows 7, I spent hours trying stuff, did boot logging, turned off startup services, piles of stuff, but didn't seem to be getting anywhere...)
    Tried using the Forum USB Key boot for BIOS flashing. Couldn't get it to boot, just got black blank screen with cursor. (Could this be because board doesn't support 98/ME?)
    Finally figured out the M-Flash option, and tried 1.4, which gave same results as 1.5. Then went back to 1.1 and that got my Win 7 booting again ok. Then tried 1.2 and that gave same result as 1.4/1.5 (screen freezing), so went back to 1.1.
    Later tested out HP USB key booter and that worked for me, though I didn't end up using it for anything, since I went with the M-Flash.
    I was hoping that this new board would help me have better eSATA (hot-swappable/recognizable), than my previous setup but it's actually worse. With my old setup, I could plug in an eSATA drive, then Add Hardware, and the drive would be recognized by Win (XP). With this new setup, eSATA drives only get recognized if I have them connected and on before I boot up my box. Not good. Also, the BIOS has a tendency to prioritize the eSATA's before the regular SATA's in boot order, which seems weird.
    Anyone else have any experiences like this? Any suggestions on moving towards a BIOS upgrade and more eSATA functionality (ideally without spending another 12 hours on it )
    Thanks for reading and in advance for any suggestions!!

    I read your solution about reinstalling the OS after a bios update (that's the first
    time that I read it and I owned something as 15 motherboards in the last 10 years...but
    you have 20k post so I think that you know what you write...)
    So I tried to REINSTALL after "upgrade" of the firmware 1.5 of the MSI P55M-GD45.
    I did it with a USB KEY....not [email protected] with defaults values !
    The only thing to do is downgrade the bios in 1.1 and now no problem @ 3.8 GHz !!!
    WHY IS THIS BIOS SO unstable ?
    What will MSI do ?
    I have never had a so unstable motherboard after a bios upgrade !

  • OCing won't work - P55M-GD45

    Hey, got my new P55M-GD45. Has a bunch of OCing features and has gotten many good reviews. Most every review I have read about it has mentioned that the board overclocked extremely easily and was very stable.
    All I want is a very slight to modest OC. The first thing I want to do is at least get my DDR3 1600 to run @ 1600 speed. I know JDEC specs DDR3 up to 1333 and that you have to manually set it for most motherboards. So I try to do it the simple way and try setting the XMP profile. It shows the adjusted speed at 1600 and then I reboot. Doesn't work, have to clear CMOS to get anywhere again.
    I have read of people using the EXACT same RAM as me and the EXACT same motherboard and they were able to set the XMP to "enable" and it automatically ran their RAM @ 1600 speed. The stock voltage is 1.5v and it's rated to run 1600 at 1.5v. Everything I read, people are running these stable at 1.5v at the rated 1600 speed.
    I have tried messing with the Base Clock. I upped it to 160 (from 133) to have them run @ 1600 (I lowered the CPU multiplier so the CPU would still run at the stock speed of 2.9GHz). Doesn't work. Have to clear CMOS to get back to working condition.
    I have disabled "Spread Spectrum" and the "Overdrive Protection" options in the BIOS because it says to in the manual if you plan on OCing. I have also done it with them on.
    I don't get why this motherboard won't hold VERY slight and simple overclocks. Overclocks that aren't even really overclocks, just bringing up some RAM to run at the speed it is built to run at, and has run at for many other people on this board.
    I am using BIOS v1.5 and Windows 7 Ultimate 64 bit. I have read in a few places that BIOS v1.5 doesn't work well with OCing. But when I try to run BIOS v1.4, it won't boot with both sticks of RAM. It will boot with each stick separately so I know it's not the sticks (They both also passed hours of memtest). Would really like to use 1.4 and see if that let's me OC. Would be even better to get XMP to work with 1.5 though.
    Thanks in advance if anyone has any tips. My build is in my signature.

    I doubt that.  What is the the model number of your memory?
    1. The memory controller is inside the processor, not part of the board and according to Intel Specifications, it support up to DDR3-1333 memory modules only.
    2.  The Chips used on your modules are built according to JEDEC Specifications but the ratings G.Skill advertises are most probably not. 
    So basically you are overclocking both the memory controller/bus and the memory chips.  And that causes problems in many cases.
    Here is a link to my memory on Newegg --> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277
    Going through the reviews, people mention the P55M-GD45 a few times and mention how easy it was to just set the XMP profile to enable for it to work as advertised. Now most of those people have an i5, I'm pretty sure I have seen this work in an i3 system though too. I have even seen people run this RAM at 1700+ with very minor volt increases. But for my purposes, 1.5v @ 1600 is very very possible with these and this board.
    Of course, anything over 1333 is technically an overclock. But it's an extremely common and safe one that any board that supports minor OCing should accept with ease.
    Quote
    Anyway, can you post a screenshot of the CPU-Z "SPD" view and the "Memory" view?
    The reason my RAM is running @ 642.5 MHz is because I tried OCing the Base Clock one after disabling "C-State" in the BIOS, since I read that helps with OCing somewhere, especially since the memory controller is on the CPU itself. Here's a pic of that...
    It shows my Base Clock at 160, and that should have put my RAM to 1600 but it didn't. It's running my CPU OC'd to 3.2 from 2.9 though and every thing is smooth so far. Going to try XMP with the C-State turned off now.

  • P55m-GD45 with G.Skill issues

    Hi everybody !
    I'm looking for help, because I'm actually using a MSI P55M-GD45 motherboad with G.Skill memory. Unfortunately, operating systems I'm trying to run are sometimes unstable. To be more precise, the first boot is frenquently unstable... some various issues may occur... like weird graphical artefacts or crashing applications. OS is sometimes crashing too.
    Memory stress tests had not revealed anything wrong, but I'm still thinking of a RAM related problem.
    Bios is set to autoconfiguration, since I'm not able to make choices about ram without being sure there are harmless for hardware. I really don't want to brick anything.
    Here are screenshots of CPU-Z results concerning my PC : if anyone could be kind enough to help me, I'll be sooooo grateful !

    my v core is set at 1.55

    agp at 1.5
    im not exactly sure what all of that is but...
    with vcore right now its 1.07
    3.3 is 3.04
    5 is 4.95
    12 is 11.96
    so what exactly am i looking for when i overclock? i have a really cheap psu so i just want to make sure everything is where it should be when i OC

    Don't look at tha numbers any software tool tells u. There inacurate.
    2 voltages are usually raised when overclocking:
    vMem, the memory voltage
    vCore, the CPU core voltage
    Raising the voltage will not make stuff faster.
    Raising the FSB (HTT on AMD64 boards) or multiplier will make the CPU run faster. At some point it will become unstable, raising the vCore can help to make it stable again.
    Same goes for memory timings and the vMem.
    Raising voltage makes componts run hotter and wear faster, occasionally u may also blow soemting up if u raise the voltage too high 

  • Vcore voltage problem.

    How come it doesn't post evertime i raise up the vcore voltage. But when i press the reset button it post up fine. It only happen when i power up the computer. I have a MSI 850 pro5 mb | 512 rdram | 550 antec ps | g4 ti 4400. This doesnt make any sense, and I'm not even overclocking it. I try everthing, even update the bios. I think msi board suck. Assaf please help :]

    I did try to overclock, but im trying to say it does the same thing even i dont try to overclock. I have a watercool system and i want to overclock it some more. Its just that it bother me when it does that.

  • Question about Vcore Voltage with 2400XP

    Hi i have been to amd site and looked up what VCore Voltage i should run my processor at and it says 1.65v and the FSB at 133MHz
    The think is the default in the bios is 1.800 and the computer works fine when bios set at "AUTO" for this.
    I changed it to 1.65v and computer will get to just before the windows logo comes up and restarts.
    If i put the FSB at 100Mhz the computer boots up fine.
    Any Ideas on why i cannot run the computer at full speed with the recommended VCore voltage of 1.65v

  • VCore Voltage problems

    Hello, again...
    I've been silent for a while(after I had to RMA board once to MSI and got new one back), just being happy my machine works. But now, after a while, I just wanted to try to get my CPU to a bit more faster settings.
    Problem is, I can't get beyond 253 FSB without raising VCore voltage from 1.6 -> 1.7. When VCore is at 1.6, CPU-Z and BIOS Health monitor shows it is nicely near 1.6 volts. But when I raise VCore voltage from BIOS to 1.7 it starts to jump between 1.8 - 1.9, both BIOS and CPU-Z shows same behaviour. It wont drop below 1.8, so it's like I did set VCore to 1.8, but I didn't. I did check..
    Now, of course, I could run it at 1.8, but it is a bit too much for my liking, I would like to use 1.7 volts setting. Does anyone else have this same problem?
    Is this BIOS problem or what? I dunno, and I do remeber that my last board(which broke) did the same thing.
    Thanks.

    Hi Lamy. 253 is nothing to complain about. I assume you are at a 5:4 ratio since your ram is only DDR400, which means you are at it's max rating. At that degree of overclock you are probably overloading your power supply at times. Have you tried dropping to a 3:2 ratio to see if the ram is the problem.
    ryede, I'm getting tired of threats from people planning on switching motherboards. Read the rules - there are no MSI rep's here; we are all users. You have one post to your credit with minimal information supplied, and to top it all you are trying to hijack someone elses post. Besides, exceeding 250 FSB is an accomplishment that few achieve.

  • Vcore voltage

    Ok just curious, what should the voltage on my vcore be?
    i think it's set at 1.5 but speedfan shows the low at 1.39 the high at 1.44 and the average at 1.41.  This is after several restarts and I'm not gaming at the moment.  Might this cause instability?

    Alrighty,  I just downloaded Speedfan 4.16 and ran a test on my system to see what results I get.
    I have:
    K8N Neo2 Plat
    Athlon 3500+
    Ballistix PC 4000
    Antec True 550
    Yadda, Yadda, Yadda....
    In my bios, I set my vcore voltage for 1.60 volts (slightly over default), yet Speenfan reports it as 1.49 - 1.52 volts ---- with cool n quiet disabled
    So it would appear your Speedfan readings would be right on par with what would be the standard default voltage for your CPU (considering the slight error reported by Speedfan)
