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 Vcore Voltage Help

    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.

    I honestly wish the mobo had manual vcore control.
    Well, it does.  You said so yourself:
    Quote
    "Cpu Voltage" it is either Auto (Grey) or increasing the voltage in increments.
    Quote
    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:

    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.
    At Idle system 32C 60watts.

    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!!

    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.

  • Alphanumeric Column Size Cannot be decreased

    I'm getting a "Alphanumeric Column Size Cannot be decreased" any time I create an alpha numeric UDF and set the length less than the default length of 10
    Any Ideas to get around this?

    Hi James,
    This was a bug in earlier patches of 2005A SP1. What patch level are you on? I think patch 16 or 18 fixed this issue.
    There was a workaround, something like changing the field type to text (without saving) and then changing it back to alphanumeric which then allows you to have a default length less than 10. Sorry, I don't have the specific detatils with me at the moment.

  • P55M-GD45 win 7 x64 1.99GB useable

    I have been looking all over for an answer for this and it all points to Memory Remapping being disabled. I have the updated BIOS (1.4) and I cant see an option to enable Memory Remapping.
    From a forum search most topics say that is enabled by default, but if that was the case then what else is the problem? I have my 2x 2GB sticks in DIMM slots 1 and 3 as instructed in the mobo's manual.
    Does this board somehow not support it? The BIOS does list both of my RAM sticks and a total of 4GB.
    **edit*
    Yes i do have windows 7 x64 ultimate

    Hi,
    There is no memory remapping option in BIOS because this feature is automatically enabled on all MSI boards featuring an Intel Chipset that natively support more than 4GB of address decode space.  Your problem has nothing to do with memory remapping.
    Quote
    From a forum search most topics say that is enabled by default, but if that was the case then what else is the problem?
    It could be a W7 problem (sometimes it helps to reinstall the OS), or, which is also possible, a problem regarding the proper contact between the CPU Socket Pins and the CPU's contact pads.  Remove the CPU from the socket and have a good look at the CPU's contact pads to find out if there are pads that do not show any imprint from CPU Socket pins.  Sometimes reseating CPU & Heatsink properly solves this kind of contact problems.

  • P55M-GD45 : MSI install disc does NOTHING

    That's pretty much it. Nothing. I put the disc in and a window comes up declaring that various drivers and utilities may be installed. Well, only the ones the program detects apply to the system. The chipset button does nothing. I click it and it presses and sits there looking pretty.
    So, without any drivers, I can't use USB, and without USB, I can't use the internet, which might actually help install some drivers. Am I doing it wrong? I tried just adding the controller's drivers from the disc, but I have no idea which one is correct, and there are hundreds of INFs just sitting around on there.
    Everything else looks good...other drivers that aren't greyed out install...whatever. Pretty much anything but what I need to proceed.
    Then I tried registering at MSI's forum for help. Bad idea!! I got an activation e-mail which did NOTHING, bringing me to a screen talking about resending an activation code. Did I forget mine? Did I get the e-mail? Want to enter in your activation code to register so the nice people can help? Whatever! None of it does anything. The most infuriating thing to suffer after the driver disc that does nothing. It's not like I haven't built a few computers before...
    Help!

    Quote
    - I have no way of transferring downloaded drivers from this computer to the new one (or detecting which ones to get automatically)
    Obviously, you have a way of connecting to the internet, which means that you are able to download the drivers.  Are you trying to tell me, that you have absolutely no possibility to get your hand on an USB Flash Drive, an external harddrive or a CD you can burn the downloaded stuff to?  If that is the case, I object to believe that it is absolutely impossible for you to change that.
