P45 Neo2 and Memory

Before you all start flaming me,  I know that my memory is not "true" 1066 memory. What I want to find out is if there is a way to make it work at that speed stable. Anywho, here's the situation.
I've got a P45 Neo2 motherboard that won't accept 4x2GB memory chips from Patriot. They're 1066MHz 5-5-5-15 chips (2.1v) and I've tested them all individually and they work like a dream.
The problem lies when I plug all 4 of them in. Unfortunately, plugging in all 4 causes the board to "boot loop" when the enhancer is on. I've tried with the memory enhancer setting off, and it will get past POST, but then bluescreens (read: fun) on boot attempt. (Note: For this I've been manually setting the timings to 5-5-5-15 and the voltage to 2.1v.) I'm not sure what I should be setting the memory sub voltages to. I've set them to 0.995v as read in another post (as well as turning off enhancer) and as I said, it POST's, but no boot. I'd really like to use all the memory I purchased and didn't realize that this would be an issue when I purchased them. I can still take them back, I've got another week on the return policy.
I can plug in two, set them to the proper voltage and speeds, and they run great. I had 4gb of memory before the upgrade to the new P45, but with all the work I do concurrently on the computer, I'd still run out of memory quite quickly, and I thought it'd be an easy upgrade. Guess not. 
The motherboard does recognize them as 800MHz chips, but after a reboot it switches them automatically to (proper?) speed of 1066.
I have plugged in one module to all four ports, and I've tried each memory module individually, so I'm pretty sure it's not the motherboard or the memory (directly) causing the problem. I am using bios revision 3.30 (updated from 3.10,) which is the newest offered by the MSI updater service. The newest out is 3.40, but unfortunately I don't have access to a floppy drive at the moment and it's not on the auto-update listing yet. (I've emailed MSI about that just today so hopefully I can get my BIOS update obsession fixed.)
So, should I just return these and buy true 1066 memory and save myself the hassle, or is there a way I can get this system stable with what I've got?
Thanks in advance,

Try again with 0.955V for both values (with DRAM Voltage @2.1V) and Spread Spectrum Disabled as well.
Can you get all four sticks to stably work @DDR2-800 @1.95V?
Please note, that the Intel P45 Chipset does not officially support DDR2-1066 (according to Intel Specifications it supports DDR2-667 and DDR2-800 only).  That and the fact that you are not using "real" DDR2-1066 memory modules, but DDR2-800 sticks that have to be overclocked and overvolted to have a chance to work stable, decreases your chances that your memory overclock will yield a stable system when all four slots are populated.  Your chances would be a lot better when you were using 2x2GB sticks.

  • How to enable Wake On Lan on MSi P45 Neo2?

    Hi,
    I just bought a P45 Neo2, and I think I have WOL on this machine, as the Realtek chipset 8111C does support the feature. However, I'm not sure how to
    - enable
    - use
    the function. Can you help me?
    Under Device Manager, I go to the Realtek network adapter --> Properties --> Power Management --> Allow this device to bring the computer out of standby.
    Now, it is enabled. How should I use it? I would be very thankful :-).

    Please have a look here first for basic introduction to Wake on LAN and "Magic Packets":

  • MSI P45 Platinum and Neo2-FR

    Hello everyone!
    I have small question will P45 Platinum and P45 Neo2-FR work fine with those memories OCZ DDR2 PC8500 4096MB KIT, Reaper HPC, 2x2048MB, Heatpipe, (CL5-5-5-18) ?

    Quote from: Jack the Newbie on 04-October-08, 18:05:31
    A few facts about the P45 Chipset and those memory modules:
    1) According to Intel Specifications, the Intel P45 Chipset natively supports DDR2-667 and DDR2-800 modules, that is it.
    2) Those OCZ Modules are essentially DDR2-800 modules (use DDR2-800 chips).  DDR2-1066 is an overclocking rating that will force you to overvolt these sticks above DDR2 standard voltage.
    3) EPP profiles are pre-programmed OC profiles that are not fully supported on Intel Chipsets but are for NVidia Chipsets only.
    The bottom line is:
    -> To run those modules @standard DDR2-800 speed should be no problem (neither on the P45 Platinum nor on the P45 Neo2-FR.
    -> Trying to get the system stable @DDR2-1066 speed may or may not work stable, as this means overclocking both the memory controller AND the modules. So, get ready to some tweaking of memory related BIOS settings (inlcuding memory voltage, MCH Voltage, DDR reference voltages and timings) to find stable settings for non-standard clock speeds.
    So I shouldn't have any problems to start computer after I connect everything? And what IF I will be unlucky and those memories won't work ?

  • MSI P45 NEO2-FR P45 - crashing while gaming!

    Hi
    I have same problem like from topic below
    https://forum-en.msi.com/index.php?topic=119789.0
    That was some problem from the beginning, computer was restarting it self with no reason or just restarting while was booting every few secound and the this message appear "overclocked failed" or something.
    Somebody told me to try upgrade BIOS which resolve this problem.
    Now only problem I have is happening during the gaming. Operating system (WIN XP MCE sp3) seams to be stable but when trying the game computer will switched off it self after few minutes, like somebody just cut the power off!

  • P45 neo2-fr system will not boot at all

    CPU: Intel 2Duo, 3GHz, LGA775
    MOBO: MSI P45 NEO2-FR
    RAM:  2 x 1GB Kingston DDR2 , 800MHz
    VID: 2 x Asus EAH4850, ATI crossfire
    HD: Seagate Barracuda 750GB SATA
    Power: Antec 850W TruePower Quattro
    Optic drive: DVD/CD burner
    I cannot get this system to boot up.  Everything powers up.  The hard drive is spinning, the fans on the vid card and CPU are spinning, and the CD drive lights up and seems to “POST”.  Nothing comes up on the screen (and I’ve checked the monitor, it works).  There are no POST beeps either.  I had assembled the entire machine (dual vid cards, and two other PCI cards), but when it did not boot, I started the troubleshooting.
    I’ve tried an IDE HD.  That didn’t work.  I’ve even took out all the RAM to see if I could even get a POST beep…nothing.  I have the setup now at its basic build; CPU, RAM HD and one Vid card.
    Does anyone have any ideas or know of what the issue may be? 
    thanks

    The machine it back in it's case with all cards and connections and is booting up with the OS that is on the HD (I'll be wiping it for this new config).
    I put paper washers between the mobo and risers, that was a trick in itself. 
    So as of now, I'm good to go.  Now comes the software terrors.  But that's for another thread...
    Thanks again Jack! 

  • Having problem with extra DDR2 for P45 Neo2

    Having problem with adding more DDR2 to my P45 Neo2. I currently have 2x hyperx 2gb ram installed, but I would like to take it up to 8gb. I had purchased another set, installed and pc wouldn't load. I installed these into another pc and they worked fine. What am I missing? I have tried googling but cannot find the solution to my question.According to MSI it will take DDR2 800/1066/1200. It does not mention what module name it takes eg pc 5300, which I'm quite sure are the ones installed. I have just updated the bios to the most recent should this help?

    Guessing you have all RAM related settings as "auto"?
    Does the PC work with your new set only?
    You may need to set the RAM timings&voltage manually in BIOS to common factors
    that are valid for both your new and old RAM kits.
    These settings you will do with your old kit in place, save in BIOS, exit and power down.
    Insert the new kit in addition, see if it POSTS. May take a few tests to succeed.
    CPU-Z program can help to figure some of the parameters.

  • Does a P45 Neo2-FR, P45 Neo2 use the same bios?

    I'm going to be building a PC for a buddy of mine and the P45 Neo2-FR would fill the bill nicely. I went to MSI to make sure a Q9550 was compatible and to see which bios version is needed for support of said processor. I can find no listing for the P45 Neo2-FR. The P45 Neo2 is listed is it the same? If so this is not much help as the list of supported CPU's only lists the latest bios 3.1 that just came out. So what CPU's are supported by 3.0?
    I also see people are having problems with some video cards in the first PCIE slot and there is a beta bios to fix this problem. Is this a problem only when using ATI 4xxx video cards? I was planing on using a 4870. I sure do not want to deliver the PC with a beta bios or with the graphics's card in the second slot. Is this a problem only on the P45 Neo2-FR or all MSI P45 boards that support Crossfire? If not which ones do not have this problem?
    This build does not require Crossfire but I picked this board because it has better chipset cooling than P45 Neo3's have. The Neo2's also have 6 USB ports naively while the Neo3 has only 4. I also thought about using a P45 Diamond as it has built in SB XFi but it is water cooled. Seems all high end MSI boards have gone to water. Nice for extreme overclockers but the rest of us have no need for such things.
    Any input greatly appreciated.

    He is talking about P45 Neo2 Series boards.  All revisions use the same BIOS Versions [A7512IMS.3xx]
    I think if you read, the person mentions the Neo3 as well.
    I have just check MSI Global and there is only 1 p45 Neo2 listed??????
    The only ones with F & FR are Neo3 series.........

    I too have problem with the GTL settings in my MSI P45 Neo2.
    I do not hav sufficient GTLREF Settings on the BIOS(Not high enough)
    Do u have a BIOS that can fix that?
    If so can you give me the link plz.

  • Neo2 plat memory issues

    Well, I have to complain first like everyone else    I am really not happy with this board, haven't gone with MSI in a long time and doubt I will again. This is my second neo2, and I can't seem to solve the problem. This replacement board will do over 280fsb so I guess that is a plus, but anyway on with my story... system is winchseter 3200+, antec neopower 480w, x800 xtpe, audigy 2...
    I have a 1gb OCZ PC4200 EL kit, the sticks are not memtet stable together in dual channel at stock speeds (ddr533 2.5-3-3-8), they error out in under 2 minutes with test #5. I have tried 2.75v to 2.85v, and with the CPU underlocked by 200 mhz... I even tried using my ddr booster to apply these voltages. Yet when I run each stick by itself at these speeds they will pass memtest every time. If I clock down to ddr440, the sticks will complete a 16mb superpi  in dual channel and pass memtest. I have a 50cfm sunon fan blowing on the dimms. I have stripped my machine down to nothing but a cpu fan, floppy drive and a pci voodoo 4 to see if power waas the issue. Lastly, yesterday I picked up another 3200+ just to see if it was the ondie memory controller that was the problem. I have been talking with OCZ on this one as well, the frusturating thing is I hav RMA'ed two 1gb VX kits before this one, so is the problem really the memory? I just don't know anymore which is why I'm here looking for suggestions. I have also tried slots 3&4. This whole thing started back in January, its now the end of Feb and my system still doesn't work properly
    Thanks in advance.

    I can't see the MSI problem here?
    You have a Winchester CPU, as above mentioned, it's extremely picky with memory. That's AMD-related, not MSI.
    You can successfully run the motherboard to a FSB @ 280MHz, is that bad?  I believe that 200MHz is what the components are designed for? So, again, not MSI-related. This is user-related.
    If you're dissatisfied with the overclocking features of your Winchester, go get another CPU. Quit complaining about MSI's supposed inferior board.  Also, OC-related posts should be made in the OC forum section.

  • MSI P45 Neo2 FR need to know voltage settings.

    Hello.
    Ok, I have a question about my voltage settings in the bios.
    Particular for the FSB voltage and the northbridge voltage.
    Can anyone tell me what the voltage settings are when they are on auto?
    I have no idea in which manner to up the nb voltage to give my ram some more oc headroom.
    I have 4x1 Gb team Xtreem cas3 ram i can't get it over 1000Mhz. These are D9 chips and run up to 1200Mhz 5-5-5-15 2.4v.
    But this board does not seem to like it.
    So any tips how to set the voltage and in which steps to increase them?
    Thanks for your time.
    Specs:
    MSI P45 Neo2 FR bios 1.1
    Intel Q6600 @ 3.6Ghz 9x400 1.47v
    Team Xtreem 4x1Gb 964Mhz 4-4-4-10 2.25v
    Sapphire HD 3870

    Ok. I have tested both kits.
    I have ran them both at 1100Mhz 5-5-5-15. 2.35v. Just to check again if it wasn't the ram acting up.
    This was done by leaving everything on auto except CPU voltage, RAM voltage.
    Now i am gonna try to get 1 kit running at 1100Mhz again but then switching to manual on the MCH settings.
    Then i will pray that if i find the right setting for one kit so that if i add the other i only have to up it a notch to get it working like it should.
    Edit.
    After an hour of fiddling i can now boot 400 x9= 3.6Ghz on 1.47, 4x1Gb 1066Mhz 5-5-5-15 2.35v, MCH 1.3v.
    Thats nice.

    - HIS HD3870 IceQ Turbo 512MB DDR4

    - Corsair TX650W
    Okay the problem is,I hve assembled the system with the above spec and hve noticed that there is no display,I tot it was maybe a bad graphics card problem but when I swapped to other cards as well,there is still no display..I hve no idea what to test on next..I thought it may be a bad RAM as well but I used the RAM 3 days ago and it worked fine...any help or suggestion? Thanks

    DOH!  I have no idea how I got it in my head that this was about the E7200. 
    Yes, Wonk is right, it's not on the supported list.
    You could try contacting MSI, but I'm doubting they state that it can work or be able/willing to make a custom bios so it will.  Won't hurt to ask though.

    Okay, try this:
    - connect all case wiring for front-panel stuff to the mainboard or short the two pins for Power-On on the mainboard's pin header with a screwdriver.
    If that does not work:
    - take the board out of the case to test it on a non-conducting surface in barebone configuration (CPU, video card, all power connectors, one stick of RAM) and repeat the step above
    If that does not change anything:
    - test with different PSU
    Case closed, i put the motherboard outside the case and worked like a charm, seems like a bad conduct between the motherboard and the case, thanks for all the answers guys, it was the only thing i didnt examined and thankfully it was it and not some DOA board. Thanks again.

  • Neo2 Platnum - memory ratio issues, please help!

    hey all
    very strang stuff...
    just got a 3200+ winchester .90 CPU, its nice. also have 2x twinx corsair 3200 non LL ram.
    idea: I had in mind that since my ram doesnt OC very well (220 max) I was going to get the neo2 and play with the FSB and set the ratio of the ram to 166 or something so that I could up the FSB which would in turn up the ram to around 200 or a bit over. thats the idea anyways...
    result: initially I could not even post with this ram, had to flash to 1.3 but now it works. when I try to set the ram to 166 and start upping the fsb, I can get to around 220 fine. any more than 225 and I cant post... huh??? the ram is only running at 183 or so mhz at this point so I know its not that. I raised the voltage of both the cpu and ram to 10% and 2.80v and still had same problem...
    ok, so I thought I would just change the fsb to 133... well again around 225 or so I cant post... ram is running at 150 only then, so definately not ram. I am lowering the HT to 4x and 3x and still no difference..
    my last resort was 100mhz.... well oddly enough, when I set the ram to 100 I can up the FSB to 270 and it posts! I can boot windows at 260 fine, cpu is 2600 and ram is 133 at that point... well the ram doesnt bench too good there obviously, like 3100 in sandra.
    the only other thing I could thing of was upping the FSB as high as I could go to get the ram up there and lower the cpu multi while leaving the ram at 100... I was able to get it up to 300 which the ram runs at 150 and booted into windows. but zcup said that HT was running at 300mhz... when I tried to up it from 3x to 4x it posted all weird, so I dont really want to stay at that level...
    anyone else had issues changing the ratio?? I tried 1.37 with the same result.
    facts: in 1:1 I can run up to 220 and boot windows, so ram runs fine at 220
    : the CPU runs fine at 2.6ghz so the cpu is ok
    the only conclusion I can come to is that the motherboard is wacked out.. I think the bios is crummy or something. I cant afford new ram; I only wish I could change the multi on the CPU!! waaaaaa
    any thought are appreciated

  • Get CPU and memory usage

    Hi!
    I would like to know if there is any way of getting system CPU and memory usage using Java code.

    I want to get the system CPU and memory usage using the performance monitor dll, the perfctrs.dll, but access this data using Java language.Then you should create wrapper dll between your java code and perfctrs.dll and convert data from format of dll to format of your java code.
    So, that is next question - how to create wrapper dll, how to deal with or how perfctrs.dll works?

  • What is the difference between Azure RemoteApp Basic vs Standard Plans in terms of compute cores and memory?

    So our customer has asked us to compare compare Amazon Workspace and Azure RemoteApp offerings for them to choose from. While looking at Amazon Workspace, it clealy defines bundles with specific CPU cores, memory and user storage. However, Azure RemoteApp
    only specifies user storage and vaguely compares its basic vs. standard plans in terms of "task worker" vs. "information worker"
    I tried looking up its documentation but couldn't find specific CPU cores that are dedicated per user in basic vs. standard plans. I have following questions:
    Can anyone point me in the right direction or help understand how many CPU cores and memory are dedicated (or shared) per user in each plan?
    Our customer would most likely need a "custom" image for their custom apps. Is it possible for us to choose specific CPU cores and memory for the users to be able to run their apps in azure remoteapp?
    In case i am misunderstanding the basic difference between AWS workspace and Azure RemoteApp, i'd appreciate some help in understanding it as well.
    Thanks!

    Hi,
    With Azure RemoteApp users see just the applications themselves, and the applications appear to be running on their local machine similar to other programs.  With Workspaces users connect to a full desktop and launch applications within that.
    1. Azure RemoteApp currently uses size A3 Virtual Machines, which have 4 vCPUs and 7GB RAM.  Under Basic each VM can have a maximum of 16 users using it whereas under Standard each VM is limited to 10 users.  The amount of CPU available
    to a user depends on what the current demands are on the CPU at that moment from other users and system processes that may be on the server.
    For example, say a user is logged on to a VM with 3 other users and the other users are idle (not consuming any CPU).  At that moment the user could use all 4 vCPUs if a program they are running needed to.  If a few moments later
    the other 3 users all needed lots of CPU as well, then the first user would only have approximately 1 vCPU for their use.  The process is dynamic and seeks to give each user their fair share of available CPU when there are multiple users demanding CPU.
    Under the Standard plan a user will receive approximately a minimum of .4 vCPU assuming that the VM has the maximum number of users logged on and that all users are using as much CPU as possible at a given moment.  Under the Basic plan the approximate
    minimum would be .25 vCPU.
    2. You cannot choose the specific number of cores and memory.  What you can do is choose the Azure RemoteApp billing plan, which affects the user density of each VM as described above.  If you need a lower density than Standard you
    may contact support.
