MSI P7N Diamond nForce 780i CPU power connection

Hi guys quick question The CPU power on the P7N connection has a 4 pin and anther 4 pin with a plastic cover. My power PSU have also 4 and for 4 pin connection for the CPU power.  For the Q9300 do i need all 8.
Let me know
Thanks

If your PSU has two 4-pin +12V-connectors that can be combined to fit the into the board'a 8-Pin CPU-connector, remove the plastic cap and go for it.

  • New Need Sink needed for MSI P7N Diamond nForce 780i SLi (Socket 775)

    Hi Guys,
    I've been having a problem with my machine where it will be working away as and then suddenly restart. I haven't been able to pin point the problem as it can happen regardless of applications or load thats on the machine. I've also run a couple of app's to check the RAM and its fine. The only thing I've been noticing is that the 4 cores of my Q6600 seem to be running a bit hot. On average on Idle there running between 45-55oc. Does this seem normal? I'm thinking that the cpu might be over heating when I'm running apps. I've seen one of the cores up around 68oc when under a bit of load. I'm using the stock heat sink at the moment and would like to cool things down it see if that helps. Can anyone recommend something suitable for my motherbroad.
    Thanks

    Thermaltake ToughPower 750W Modular Power Supply
    My Q6600 (also G0/SLACR but don't know what you mean by "Pro") is OC'd to 3.4GHz and has had no problems running stable.  Highest temps during OCCT/Linpack and LinX/Linpack peak at 80C 1st/2nd cores - 76 C 3rd/4th cores.  Other tests (e.g. Prime95 small FFTs) run much cooler.  I've run 2hr+ linpack tests with no errors, so I don't think you need to worry about your temps yet.
    However, may I suggest that you check into is your power supply, in particular the modular connections.  I had the ToughPower 750W Modular before upgrading to PCP&C.  I noticed that the ToughPower's modular connections had a tendency to be just a tad loose.  They wouldn't dislodge but they had a little bit of play.  I could jiggle them ever so slightly while they were connected.  As a result, the CPU power cable (8-pin/4-pin) would cause a restart upon the slightest disturbance or sensation.  I've since discovered that modular connectors also affect the efficiency, power noise levels, and overall performance of a PSU.  All in all, I plan to avoid modular connectors entirely going forward.  Many newer cases have excellent cable management features and even old-style cases can be cleaned up with a little planning and effort.  So the modular cabling advantages don't offset the severe disadvantages.  Even if your problem isn't due to the PSU, it's something I'd recommend considering replacing.
    Good luck.  Hope all the suggestions are able to help you nail down and resolve your issue.

  • Overclock E8500 on P7N diamond nforce 780i

    I have read the guides here, and beginning to understand more about overclocking. However I need to know if there is any chance to overclock my cpu with only a stock cooler. I have not touched anything inside the Bios yet, besides shutting off EIST.
    My system:

  • MSI P7N Diamond NVIDIA nForce 780i SLI 3-way brigde

    3 Way SLI Connector Model 401-MB-0023-01
    Hi there recently i received a package from your company with an motherboard MSI P7N
    Diamond, nForce-780i SLI, i suddenly understood that there were not any kind of
    3 Way SLI Connector! Therefore i am now asking how come there are none of this inside
    your package and if i want to order a part! Where do i get it from? I asked EVGA they said
    that they were chipping theirs sli bridges with their motherboard and said that is also what
    your company do as well! So i ask you again how come there is no 3- way sli connector in
    my package! Reason for this high priority is since i have 3 GTX 280 sli and i can't run 3
    -way without this 3- way sli connector!
    I live in Norway and i have been struggling with finding people who might be able to solve this problem for me!
    So i would appreciate you and the company too have a look at this case and let me know if
    its possible to get one from you! Without any money cost! And if it is possible to get one but
    it will charge then, how much? Best regards From Halvor bø

    Your board should have come with three SLI cables. Two short & one long to comprise the 3-way SLI bridge cables. Installation & full description can be found on pages 2-22 & 2-23 of your owners manual.

  • HELP! - Voltages for Overclocking Q9450 on the MSI P7N Diamond (780i chipset)

    Hey.  I fully understand the settings as far as frequencies go, but am a total voltage newb.  No matter what I do I cant seem to get a stable vista load up with my voltage settings. 
    Please help me by providing suggested voltage settings for my hardware.
    CPU - Intel Core2Quad Q9450
    RAM - 6 gigs of DDR2-800 rated at 2.1V
    VIDEO - Dual Nvidia Geforce 8800GT's in SLI
    MOBO - MSI P7N Diamond, based off the Nvidia Nforce 780i SLI chipset
    My cooling is sufficient, and I have the BIOS version 1.2
    I also turned off all of the overclocking not friendly functions, example: spread spectrum, and DOT, ETC....
    I am trying to run my CPU at 3.2 GHZ (400 mhz before multiplier)
    my settings I want are (as shown in the P7N bios)
    System Clock Mode - Manual
    FSB clock - 1600
    DRAM clock - 800
    Please help me by providing the proper voltages for my setup
    Everything I need is marked by "???"
    CPU Voltage - ???
    DRAM Voltage - (already have, its 2.1)

    For the sake of you not typing too much, if you specify voltages, any that you do not specify will be assumed to be left at [AUTO]
    PLEASE help me by providing some voltages for me, as I have absolutely no clue what to put for them.  If you have any questions about my hardware feel free to ask, and any help is GREATLY APPRECIATED

    Quote from: nihilkrist on 08-October-08, 08:03:22
    adjusting gtl ref. voltages isn't very difficult, but it is probably best to learn the basics first.
    So, basically, increase the fsb a little. So, for example, from 1333 to 1400. See if it's stable, if it isn't try bumping up vcore one notch and try again. If not try Northbridge. Then later move on to stuff like the fsb term.
    Test stability using prime95, there is a 64-bit multi-core aware version floating around somewhere. Try the ftp server linked to in the "hot use prime95" sticky on here.
    Tbh with your OC you shouldn't need to touch any other voltages, or really use the gtl ref settings. What exactly is "sufficient" cooling though? Stock?
    *EDIT: on a side note, just so you don't think I'm deliberately being awkward not telling you specific voltages, they wouldn't do you any good. Every cpu/mobo can handle different freq. at different voltages. Also, use cpu-z to check on your actual voltage and make sure you don't raise it beyond 1.3625 (I think that's right, it's 1.36something anyway)
    Thanks for the tips.  The reason I wanted to jump straight to FSB 1600 is because the MSI p7n is really picky and only likes 1:1 ratios. 
    My "sufficient cooling" is an aftermarket heatsink, high performance thermal paste, and MASSIVE airflow through my case.  If you want specifics, its the Scythe Zipzang
    Quote from: AaronYuri on 08-October-08, 09:05:16
    CPU Voltage - No one can tell you this.
    NB voltage - Depends on what frequency you want
    SB voltage - What's your HDD setup?
    NB Memory reference voltage - Auto
    DIMM memory reference voltage - Auto
    Memory terminator voltage - Auto
    CPU GTL reference voltage - Depends on speed and other voltages
    NB GTL reference voltage - Same as above
    FSB terminator voltage - Depends on CPU voltage and CPU/FSB clock speed
    SB sleep mode voltage - Auto
    PCI Expander PLL voltage - Auto
    My recommendation is do some reading. Guessing leads to dead hardware.
    6GBs smells like mixing modules... Or do you have 3 modules?
    First of all, I already stated the frequencies that I wanted in the top post, and fairly clearly at that. 
    CPU shouldnt be too hard to figure out, as there are very few to choose from.  I'll try to get back to you on that one
    I have 5, 7200rpm SATA 3.0 drives.  It sometimes runs with only 4, as one is a hot swap. 
    My ram IS mixed, unfortunately.  I'm using 2x 1gig sticks, and 2x 2gig sticks.  However, both sets have heatsinks, and are rated at 800mhz, 4-4-4-12, 2t, timings.  (2.1v)
    I AM running them in dual channel.
    If this helps you suggest voltages please do, If not, then I will just have to start trying using nihilkrist's suggestions.

    This is from awhile ago, but may have some ideas & settings that may be of use for you. The OC seemed to work better with a 1:1 ratio. Ram speed of 825 - FSB of 1650 in my case. It would not run stable at RAM speed 1066. 412.5 would net about 3.506 or so for you. Hope this helps.
    thanks for the help, I think is the problem, the memory's, I will test and see how it

  • MSI P7N Diamond Burnt Out!

    Hi,
    It's now been a good few weeks for me trying to set-up a new computer after having replaced the motherboard a couple of times and buying better power supply etc. But I've now got a new issue with this P7N Diamond and it's the second time it's happened (already RMA'd it once before with same issue). Each time it's happened I've only had the basic items connected, power supply, motherboard, graphics card, memory, cpu and fans.
    Basically what happens is that the computer powers on for a few seconds but there is an immediate burning smell from the motherboard. When I removed the motherboard I found that a thin strip of copper around the under side edge of the board, almost directly below the bottom fan connector (SYSFAN4), has burnt away exposing the cooper itself and split. I've checked for anthing shorting the board in the case and all the case/motherboard screws are in the correct place.
    When it first happened I thought maybe its the PSU (I used my older Antec 470W on the first RMA'd board) or a faulty board, so I upgraded to the Corsair PSU and got the board replaced, but its now happened again!
    Obviously I don't want this happening again so any idea what would cause this?
    Would it be the fan connected to SYSFAN4? It's a Scythe Fan rated at 0.26A and I think I had it connected both times when the board blew. If it was the Fan how would a board allow this type of thing to happen, should it not have built in protection to stop things burning out like this?

    All my fans are plugged into the P7N.  All of them came with the Cosmos case except the CPU fan which I bought seperately.  So far (knock on polycarbonate), no "charco' for a mobo".  (All fans are 120mm including the one I bought)
    I read that the Cosmos although quiet is not too good at staying cool and lots recommended changing the default cosmos fans with better ones, so I changed them all to Scythe fans except the CPU fan, which is an Arctic Cooler 12 PWM Fan, as the Sycthe's don't have four pin plugs.
    Quote from: Pchas01 on 10-May-08, 02:24:34
    And, curious, why are you plugging a Scythe fan into the #4 conector?  There are three others closer to the CPU if you're cooling the CPU).  I use all 4 connectors with no issues at all.  Last question, is it a 5v fan, 12v fan..?   Ah, good luck with the Stryker if that's what you want..it's a good board.
    I have about five Scythe Fans and one Arctic Cooling CPU Fan. The AC CPU Fan was using the CPU Fan connector and the other four connectors had the Scythe fans attached. I just thought it had something to do with the #4 connector because the burn out was so near. The Scythe fans are 12v, could that be the reason?
    Yeah I got the Striker II board now, but seem to be having the issue I original had with my first MSI P7N board with the Coolermaster PSU it just flashes on for split second and cuts out. I thought having this Corsair 750W PSU I wouldn't have that issue any more. As soon as I plug in my cheap gfx card it works fine! I just seem to have no luck at the moment. (Yes I've got the gfx power plug in )
    Quote from: NovJoe on 11-May-08, 12:57:46
    Sound like a surge shorting either from the fan or the chassis.
    Try removing some of the unneccessary standoffs and see if problem re-occurs. 2 boards can't have the same problem repeat that easily.
    I only had the standoffs for the nine holes in the board so should not have had anything shorting it out.
    I got a ASUS Striker II now anyway and so far it works, but I'm only powering the CPU Fan from the board now, all the others I'm going to do direct through the PSU. Just need to get it working with Geforce 8800GT now.

  • Msi p7n-diamond and coolermaster hyper48

    Hi friends
    Just wanted to know whether coolermaster CPU cooler Hyper48 will fit with msi p7n-diamond mobo with intel q6600.Will it work?
    Kindly suggest

    I can't answer specifically, but did purchase and install a Rosewill RCX-Z4 120mm 2 Ball CPU Cooler for my p7n board with an E8400 processor.  I looked at that Coolermaster product but was a little concerned it wouldn't fit because of the heat pipes.  I opted to use the Rosewill brand as it had a better form factor, and it vents out the top of my case. 
    My only complaint about the Rosewill is you can't get to the CPU power connectors on the board (8 pin) inside the case with the cooler attached.  The fan assembly gets in the way.

    If it really was 2.64V on the +12V rail, your MOBO wouldn't even post.  That reading is a wrong reading.  What are you using to check the voltages?  What is shown in the BIOS?
    i really had serious problems .Two A..S Striker 2 Extreme down ,2 MSI P7N2 diamond mobo down {[3 x ( start,5sec -> freze)] and no post anymore} And suddenly the third  P7N2 Diamond  working.
    Nothing changed. How to explain this?

  • MSI P7N Diamond - New PC Build - Need Help Posting

    I just finished connecting my P7N Diamond out of the case and powered on my new build for the first time and saw BIOS version, HDD information, and the bad checksum message on the screen. I also saw the "Press DEL to enter BIOS" and the "F2 To Continue" messages.
    Pressing the DEL key on the keyboard resulted in nothing happening at all. I soon realized that the keyboard wasn't responding and I had no num lock light at all after pressing the Num Lock key multiple times. I started with a generic, USB keyboard and then swapped keyboards to an older, still working one I had with a PS/2 connector.
    Still no keyboard lights but magically it entered BIOS after I plugged it in the PS/2 socket and immediately asked if I wanted to exit BIOS  without saving. Pressing the "Y" key did nothing. Pressing <ESC> did nothing. The keyboard seemed frozen.
    I pressed the RESET button on the motherboard and this caused a re-boot but now with a black screen (no messages at all). I powered it down, removed the power cords and then pressed the "clear CMOS" button. Re-connected the power cords and powered it on; but still a black screen. Powered it down, removed the power cords and removed the battery for 1 minute (I even pressed the clear CMOS button again). Re-connected the power cords, powered it up and still have a black screen.
    I know this is the place where all the experts hang out, so any help will be appreciated.

    Just an update...
    New build is working very well at this point.
    I've set the voltage in BIOS to 2.1 for the memory and installed Vista Ultimate, updated it via Windows Update site, applied the memory patch. I've discovered that I have a bad stick of memory as no matter what slot I place this one stick of memory in, the PC fails to post, so I'm running with 3x1GB sticks. I've ordered new memory that should be here today; Corsair TWIN2X4096-6400C5DHX.
    The only problem I've encountered thus far is with one of my NVIDIA RAID arrays in "Degraded" status (mirror broken). This happened after I had applied the latest MS patches and a re-boot. I didn't suspect a HDD failure because the drives are new and the status of each drive was displaying as HEALTHY. I did my research on this site and discovered the solution which was to delete one of the two drives (I chose the one with the least amount of data) from the array and then added it back into the same array. The re-build took about 2 hours (they are 400GB Segate drives) and now it's working as advertised. I suspect a software problem caused this as one of the two drives was showing that it had less data (used) than the other drive.
    My next steps are to install the new memory, test it with memtest86+ and then begin the OC ritual.
    Thanks again for your help, Jason and Aaron Yuri.

  • MSI - P7N Diamond ESATA doesn't work under XP

    I have 2 P7N Diamond motherboards and am running XP Pro/sp2.
    I have never been able to get the esata ports to work. I have spent the last 4 months RMAing boards back and forth to MSI. I have tried at least 4 motherboards, 3 esata external drives, and 3 cables (all 6 feet).
    Sometimes on the upper port (lower port doesn't work at all), the drives get detected in bios as gibberish. Other times it is listed correctly in post, but then I get a "9th slave hard disk error". I press F1 to resume, enter the bios, and the drive shows up. The drive never gets detected in windows, however.
    In bios I have the Extra IDE/RAID Controller enabled and RAID mode is set to IDE.
    In XP I have the JMP36X IDE Controller installed.
    During all this time, MSI Tech Support has insisted that I am doing everything right. I called them last night and they mentioned doing an rma yet again, but when I called back today and talked to someone else, he told me that esata only works under vista in AHCI mode. He said that it won’t work under XP in IDE or AHCI mode.
    Hope someone can help me!!

    Thanks for the reply.

    Have you tried to install the RAID controller driver using F6 option by using the XP installation disc?
    I did that when I installed XP. 
    Someone provided this link to set up AHCI mode. Plan to try that in the next day or two.

  • MSI-6738 KM2M Combo L CPU power socket (4 wires)

    Just a quick question. I just bought this board and it has a 4 wire connector next to the ATX power connector and my power supply does not have the 4 wire cpu power connector. Do I need to buy another power supply, or can I use the existing one and just use the ATX power cable. will this do any damage to the CPU and or power supply.
    Thanks.

    i have asked a lot of people and thay have all told me theat you have to have the 4-pin plug conected. but i was faced with the same ishow my psu dosnt have the plug. i didnt have anuff cash at the time to get a new psu so i just pluged then the atx power plug and it has worked fine boots fine and runs stable. then i talked my uncle in to buying then same board and he got a new case wen he got it the psu that came in his case hase the 4-pin power plug so i pluged it in wen i put it together and has workes fine to. so ovisly you dont have to have then plug even thow it is recomended y duse the board have the plug and can or will it hurt my componets if i use the board without it if you have any comenta please e-mail me at [email protected] thnx

  • X58M CPU Power connection...

    Hi all...
    I recently got a barebones kit with the X58M mobo... I've had nothing but problems so far.
    This question is mainly about the CPU power connector though. I noticed the CPU power connector on the board has a small plastic "blocker" over 4 of the pin connectors. Is this just for packing and shipping? Should I only use the 4 pin connector from my PSU in the "open" sockets or should I remove the plastic blocker and use the 8 pin connector? The Manual for the X58M shows the CPU connector as a fully open 8 pin socket...
    Originally I removed the blocker (so it was like the manual) and used the 8 pin connector... I got all of 2 seconds of a boot (the logo screen only) then nothing. Could this be the problem?
    My symptoms are as follows if this is any help... First ever power on - Logo screen, followed by blank white screen and nothing else. All power ons following - No video signal and one short beep every 30 seconds or so.
    Please tell me I didn't fry the CPU!
    I have tested all the memory sticks, one at a time. I have reseated all the components. I have tested the board outside of the case with just the CPU, Memory and Graphics card. I'm convinced there is a problem with the board, but I'm no rocket scientist...
    Current (attempted!) system specs:
    X58M
    6Gb Corsair XMS3 (3x2Gb)
    Intel i7 940
    Geforce GTX 550 Ti (1Gb)
    Cooler Master Hyper N520 CPU cooler
    Cooler Master HAF 912 Case
    Ultra LSP 750 PSU
    DVD-RW
    1x Seagate 1Tb SATA Drive
    2x Western Digital Caviar Blue 500Gb SATA Drive (Raid 0)
    Thanks in advance for any advice...

    Yes.

    It is there so that users who have a PSU with only a 4-Pin connector, won't plug that 4-pin plug into the wrong part of the board's 8-pin connector.

    No, unless you put a 12V PCI-Express power plug into the 12V CPU Connector.

    Test the board outside the case on a non-conducting surface in barebone configuration.
