MSI P55M-GD45 Memory Problems

I cant get my memory to the 1600mhz that i bought it for, my motherboard is only reading it as single channel memory and it's telling i have 4gb worth of memory but only 1.99gb is usable. Im a noob so i have really no idea about anything so can someone help me.

Show us the SPD tab.  To make you signature more complete, please list the amps on the +12v rail(s).
here is the spd tab for both sticks of ram:
Stick 1:
Stick 2:
and this is the link to my power supply and it specs(I guess it has 22 amps but i'm not sure so i provided the link):

    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.
    XMP off/Turbo off (133X20=2.66)
    4 cores 100% 61C
    1 core 100% 49C
    XMP on/Turbo off (160X20=3.2)

    1 Core 100% 58C
    XMP on/Turbo on

    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.

  • MSI Z77A-G43-memory problem

    Hello
    I bought lately new cpu,mb and memory. When i turned it on it was still rebooting after few seconds after start. So i treid to put just one memory in slot. It worked but only if memory is in bank 3 or 4. In 1,2 computer is still rebooting. Also it works with two memory modules, but putted in 3,4 slots only. And just in single channel. I saw that many people have the same problem and shop service wrote them that it works like that. First You put memory in slots 3,4 and then in 1,2. It is strange for me. I don't have two another memory modules to check if this is true and I want to that it works in dual channel, not single. So, is this true or mb is broken?

    Hello. I have the same problem, except, I use 4 Dimms in 4 slots on my MSI board. I installed speaker on MB to see if there are any beep sounds during the booting, but all seems ok. The problem is the PC keeps still rebooting after about 5 sec. from the start. There aren´t any visual information on screen, since the start is so short. I tried to install dimms in 2nd and 4th slot first. Then to 1st and 3rd. In both cases the problem was still the same. When I put all rams in all 4 slots, the result is the same (restart for ethernity). The only way that goes is the PC runs with only 1 dimm in either 1st or 2nd slot. I tested all the memory modules and all of them work fine. I even tried this on a differennt mainboard from ASUS P8Z77-V LX. Now I tested it on MSI Z77A-G43. Both mainboards are new. There is a very slim change that both of them would be defective. Before I got MSI MB, I ran couple of days on the ASUS MB and everything was perfect, so I don´t think that CPU is defective. I even ran a few benchmarks on it. But I still don´t understand why can´t I run the system with all 16 GB of RAM instead of 4 GB in one slot. Please help me.   

  • MSI P55A Fuzion Memory problem

    I have a problem that i am trying to solve so I need your help.
    My motherboard MSI P55A Fuzion detects memory 12 GB  Kingmax (2x4GB DDR 3 1600 and 2x2GB DDR3 1600) but my OS is showing 1g GB but 6GB usable memory.
    I have googled a couple of topics on that subject but haven't really found the solution.
    BIOS version is 1.20, my operating system is a windows 7 64 bit that supports more than 4 GB 
    I also tried stacking the memory one by one and with 3 sticks i could get a 10 GB full.
    I don't think it's an OS issue since i checked out max memory in advance boot options.
    Please help me out, it's really getting on my nerves 
    Thanks in advance.
    Stija

    Mixing memory is the way to make sure you are running into problems. While using four sticks is already maxing stress for the ram controller you are also mixing capacities and different ram srticks. Get a proper matched kit and it will work.

  • MSI 845 Pro - Memory Problems

    I have an MSI 845 Pro(FC-PGA2) mainboard.
    So far I have tried PNY PC133 129MB DIMMS and Windows keeps resetting itself at random intervals or the logo screen pops up and it will reset.
    I then tried an unbranded make of 256MB and it kept freezing during installation.
    The only memory that does work is Kingston 65MB PC133.
    I have now very PO`ed if this mainboard will not accept any other brand of memory.
    Please if you have suggestions then post them or PM me.
    If you have had the same problem also please contact me.  X(

    Run memtest86 on each stick

  • MSI P55-CD53 Memory Problems

    I have a P55-CD53 with a 4GB memory kit from Crucial (CT2KIT25664BA1339) that according to Crucial is recommended for my board.  I am running win 7 x64 Ultimate for my OS. 
    I have read a few posts that mentions changing voltages to 1.575 and charge time to 2T and it seemed to work for most. I tried 1.55V with the 2T and I still had crashes and blue screens.  I tried 1.6V and my machine did not boot, just a blue screen with memory error detected.  The next time it did boot, but I noticed that the memory voltage had gone back to auto.  Many more problems and I changed back to 1T also.  Now I am able to use my machine for more than a few minutes.
    I have tried just to let my machine idle overnight and it has always had a blue screen in the morning.  I went to the Crucial site and they mentioned a program to test my memory. http://hcidesign.com/memtest/  That program will throw errors and blue screen my machine.
    So I tried memtest86+ off of a boot disk.  I ran it for over 3 hours with no errors.
    I noticed others have posted images of their memory so here is mine.  So what can I do to get this machine stable?  By the way I am not overclocking.

    Quote from: Spg on 21-February-10, 06:36:11
    No Joy!
    I would make the BIOS changes and save them.  Then my machine would start to reboot, shut down and the boot back up again with the original settings.  The only setting that would stick is the memory voltage.  I then tried to change the base clock from 133 to 150 to get the memory into the 1466-1600 Mhz range, with all the other settings, and I booted to a message saying the overclock failed.  So I am now back at the default (auto) settings.
    Mike is right, but this mainboard has no problems with real DDR3-1600.
    In any case, be sure your processor is fully supported by BIOS:

    Now i have 3gb ddr2 from Geil
    it's pc2 6400 800mhz cl 4-4-4-12

    I installed Vista 64 home premium and bought 8 gigs DDR2, it's 2 sets of 4gb
    this 1: http://www.geil.com.tw/products/showSpec/id/52 they have thesame specs only its cl 5-5-5-15 and 1.8v instead of 2.1 volt, my old are 2.1V.
    When i plug em in and turn on my PC i wont get any signal AT ALL, my monitor doesnt even react and stays on standby mode. I re-plugged my old memory and everything works fine. I changed the volts, which were on 2.1V, to 1.8V in my Bios and tried again, no reaction. I tried several combinatiosn and only 1 set of the new memory but it doesnt work.
    Is it mayb the BIOS that needs an update or should i change Volt AND the CL 5-5-5-15 timings?
    According to the website of MSI my mobo would be able to use the new memory i bought doesnt it?
    I hope any1 of u experts got an idea =)
    thx
    Gaarman, holland.

    Well, put command rate at 2T and try all 4 sticks, however it might fail again as the CPU needs to be able to start before the BIOS kicks in.
    Judging on your higher needed voltage, these sticks are not very good....
    On your link:
    Quote
    *note: All DDR2 Value 800 modules were tested on NForce 4 Intel Edition, Intel 955 and Intel 975 platform mother boards for performance, stability and compatibility.
    This doesn't sound very promising either.
    AMD is NOT Intel, it has a far faster memory controller then the listed testing systems....else try DDR667 and see what happens if you use that speed.

  • MSI P55-GD65 memory problem

    I have a problem with memory in Windows 7-64bit.  It only use 3GB of 4 GB, despite the fact PC recognize all 4GB RAM. It say that 1 GB it's hardware reserved. Today I updated BIOS to 1.5 version due to announce that "Fixed system report incorrect memory size when install 8G memory"
    What I've already done:
    1. Checked the socket for bent pins as I found the solution in other topic here. I have a LOTES socket and didn't find any bent pin or no contact pad on CPU
    2. Swapped the two RAM modules between them. No use.
    3. Checked RAM modules in another PC, AMD processor and there was no problem, recognized 4GB, used 4GB.
    4. Run memtest86+ - no error found.
    The strange fact is that in Linux (Gentoo) I set swappines to 90(%), mounted a tmpf (3GB size) in an empty folder and filled it until it was full. No swap occurs - 3.4 GB RAM was full. (I used top). So, it seems that the PC it's able to use more than 3GB.
    I really appreciate any clue, suggestions.
    Thank you!

    I always clear CMOS after a BIOS update and  it's Windows 7 64 bits for sure.
    Some translations are required: GO=GB; utilizabile=usable;64 de biți=64 bits
    Later:
    I redo again tmfs test on Linux. System is hardware capable to use all 4GB. So I decided to reinstall Windows because it was preinstalled by my PC vendor. It didn't bother me until now.
    And... big surprise: Windows recognize all my 4GB. Well, so far, so good. I installed drivers from Intel, Realtek, Logitech and Hauppage. No problem with memory. The hardware reserved memory it's now 9MB + perfectly normal.
    Now, I remained with curiosity: what was the problem ? OS - it can't be, old drivers, bloatware preinstalled apps ? I suppose I'll never find out.
    Thank you Jack t.N. very much for your support.

  • MSI Z68A-GD80 Memory Problem

    I've had an issue with this motherboard since I built my computer back in May, it will not POST whatsoever if I have my RAM in dual channel mode with memory in DIMM 1 and DIMM 3, but it will boot fine with one stick in DIMM1 or 2 sticks in DIMM 1 and 2. I've tested each stick of RAM individually in slot one and they both work fine by themselves. Any help would be appreciated!
    Specs are:
    Intel i7 2600k, MSI Z68A-GD80 Mobo
    (2x4gb sticks) 8gb Corsair Dominatior GT RAM 1.5v
    EVGA 580 GTX

    1.5TB Western Digital Caviar Black HD
    910w PC Power and Cooling PSU
    Zalman 9900 Max CPU coole
    Corsair 800D case

    My theory is you have some bent socket pins or the CPU cooler is torqued down incorrectly.

  • MSI Z77A-GD65 memory problem

    I bought a new cpu,mb and memory. When i turned it on it was rebooting after few seconds after start. So i tried to put just one memory in slot. It worked but only if memory is in bank 1 or 2. As soon as I put a memory in bank 3 or 4, the computer is rebooting.
    When I put my modules in the 2 blue banks, the computer reboots every time.
    When I put my modules in the 2 black banks, the computer reboots every time.
    The computer works only when I put my first module in bank 1(blue) and the second in bank 2.
    Itested my memory modules in an other computer and they are workin.
    Who can help me?

    Remove the cpu and inspect the Cpu Socket pins, straighten any that are bent. Make sure you have a bright light and magnifying glass because the pins are very small and even a small deviation can cause issues.
    If you don't see anything there, the next step would be to remove the board from the case and rebuild it on a non-conductive surface to eliminate shorts. Then try 1 stick in each of the dimms, if the same situation persists rma the board.

  • 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 !
    thanx.

  • 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!!

    you have 20k post so I think that you know what you write...)

  • Msi X79A-GD45 (8D) Power on Problem

    Dear Msi Users.
    I got a Strange problem with a Msi X79A-GD45 (8d) Motherboard.
    The Motherboard runs a Intel i7 3930K with a Kingston HyperX 32gb 1600mhz Kit (KHX1600C9D3K8/32GX), a Ati 7770 2gb, A SSD + HDD and a DVDRom
    We deliverd 9 systems and 8 of them are Working just great (Al the Set-ups are the same).
    One of them is giving strange problems with powering on the whole System.
    When i boot the Machine it goes on for a couple of Seconds (Without signal) and then powers off for 2 Seconds, afher that it boot's again and the problem is the same.
    So we tried a couple of things, change Memory kit (result the same), change Cpu (result the same), change power supply (result the same), new Motherboard (result the Same).
    Then i tried 32gb 1333 kit and the system works great, goes on like normal and boot's windows like normal.
    But when i put the 1600ghz 32gb kit back the problem is back right away. Even with a New 32gb Kit.
    The Bios is the Last version, We are in the Dark now. Is there a smart guy who can help us?
    Thnx in Advance and Greets from Holland.

    Quote from: RemusM on 24-October-12, 21:48:57
    If they need 1.65V, they are overvolted & overclocked DDR3-1333 chips for sure.
    So ...
    Be sure XMP is disabled.
    If it doesn't work on "Auto", you need to manually set the speed, timings and voltage (for 8 modules I recommend around 1.60V).
    Good luck.
    Oke will do that, does not work on auto indeed, one rimm (of 4) does but 8 does not.
    Quote from: xmad on 24-October-12, 21:44:13
    I can almost gaurantee that ram is 1333, with an 1600 oc profile.(XMP)
    So it is running at 1333 by default, this indiciates either different bios, or something different about the ram you used previously. Which was why I was thinking perhaps they switched memory makers or something. Something has to be different. The only thing you have tried differently is a different brand of memory.
    That is just the Stragest thing.
    We Orderd 9 cpu's, 9 Motherboards, 9 Dimm kits, 9 SSD's, 9 HDD's, 9 Grafixcards, 9 CPU Coolers, 36 (4x9) CaseFan's and 9 PC Cases.
    All build on one day and all works great, after 4 weeks of great use, 1 of them is giving this problem.
    In the Netherlands we call this "Schiet me maar in een balonnetje" with means "Shoot me in a baloon"
