P43 neo-f fsb wall at 417 with e8200

with the p43 neo which i believe there identical too p43 neo 3 apart from cooling on motherboard and bios versions(layout same ,features same,chipset same) ,anyway  I will hit a 417/418 fsb and will become totally unstable and freeze on me(while using dual core centre) or if using bios overclocking will reboot until it goes back to defaults, have also tried everything voltage wise, have dropped multipliers and it is definitely a motherboard fsb wall issue.
even tried putting a fan over northbridge to cool as seems to run very hot(is now just warm too touch so ok),but makes no difference to overclocking and is annoying hell outta me, as i bought an e8200 to specifically overclock and best i can get stable is 3300
an overview of my specs
coolermaster igreen 600w
msi p43 neo-f (latest official bios)
dual core E8200
xigmatek s1284 with arctic silver
A-data 800mhz ram 8gb (I have pretested in anouther machine upto 900mhz at 1.8v)
nvidia 512mb 8800gt
Asus xonar dx soundcard
samsung f1 1gb
seagate 500gb hard drive
Things I have tested
with only 2/4gb of ram
all conceivable variations of mch,vfsb,ich mem voltage etc (have not messed with clock drive and skew etc as i am not aware how they effect things)
dropping cpu multi to 7, then raising to fsb of 417 again results in restarting until defaults etc meaning board is hampering overclocking.
upping voltage to cpu-this results in absolutely no better overclocking as it is mobo stopping higher clocks.
Bug I noticed- sometimes on booting into windows after a few minutes with an overclock through bios the mch would show the mch as 2.57v in the dual core centre(i reset to defaults in dual core centre whenever it happens) dont know if this is a bug with bios or dual centre the mch in bios I have set it to is 1.35v, id imagine if it was actually at this voltage it would crash out and fry wouldnt it? but dosent seem to affect anything.
dual core centre often also shows a 1.9 voltage on my memory when it is set to 1.8 in bios, i again reset to defaults in dual core centre and appears to reduce voltage.

As I already told you elsewhere, these boards are not identical.  They are similar as they use the same chipset, but they are not identical.

while using dual core centre
Don't use Dual Core Center if you are looking for a stable overclock.

Which settings have you used.  Please write down ALL Cell Menu settings you used for the highes stable overclock you were able to achieve so far.

That does not mean much.  Different board, different chipset/memory controller, different BIOS usually mean different overclocking behaviour.  As soon as you go beyond 400 MHz FSB-Clock Speed you are overclocking your 8GB of DDR2-800 memory which is likely to be a cause of instability.  Have you raised the memory voltage at any point above 1.8V?

Uninstall Dual Core Center, it is not the best tool every conceived by men.
Further Questions:
1) Have you disabled DOT in BIOS?
2) Have you disabled EIST in BIOS?
3) Have you disabled C1E Support in BIOS?
4) Have you disabled Spread Spectrum im BIOS?

  • MSI P43 Neo series FSB wall?

    After messing about quite a bit with this board with various CPU's and Memory, reading comments by other users and OC'ers on other boards, it seems I've come to the bottom of the problem with my Memory / CPU issue's on my board.
    First once again: the used hardware
    Board:MSI 7519 V1.0 P43 Neo-F mainboard
    CPU: Intel E6550 / E6600
    Cooler: Scythe Mine rev. B, stock fan (100mm @ 1500rpm)
    Memory: 2GB kit G.E.I.L. DDR2 800 cl5 "black dragon"
                4GB Corsair XMS2 pc8500 "dominator"
                2 x 1GB OCZ pc9200 900mhz "Special OPS" (not a kit)
                2x 512mb Hynix 667mhz cl4 OEM memory (not a kit)
    Graphics card: MSI X1550, MSI 9600GT 512 OC
    PSU: LC power 650W ATX 2.02 PSU / Raptox 550W ATX 2.01 PSU
    OS: Windows Vista SP1 x64 UK
    I've tried BIOS 1.3 and 1.6 (final versions only)
    Memory shows to be in "asymetric dual channel mode" in every piece of software you trow at it. However, preformance is good.
    Both Jumpers have been removed from the board, setting it to "333-400 mhz mode".
    CE1, Spread spectrum, Speedstep and "OC boost modes" are disabled.
    Memory is on auto (which results in 5-5-5-15) at 2.1V
    MCP voltage is on 1.100 (since I don't want it to go over for no reason)
    CPU core is at 1.375V in bios, resulting in 1.356~1.378V in CPUZ and Coretemp. (varies with every boot)
    I've tried with both my E6550 and a borrowed E6600, but for some reason, the board will not pass it's POST at any FSB higher than 415mhz.
    (resulting in 830mhz DDR2, and a 2904mhz for the E6550 and 3733mhz for the E6600 (at 1.388V))
    This all makes me wish I got the older E6600 instead, eventhough it gets quite hot. Which brings me to the topic of temps: E6550 OC after 1 hour Orthos = 54degrees. (and 33 / 39 idle) For some reason, Windows prefers core2, which Idle's a lot higher (39) than core1.(33)
    The E6600 got to the awefully high temperature of 68 degrees after 2 hours Orthos.
    But now the issue: As soon as I pop the FSB to 416, 417 or 420, the system will no longer boot, and I will get the "OC failed" message after shutting the power down.
    I've read quite a few reviews and many people seem to encouter these problems. Boards with same chipsets, seem to go to quite a bit higher. (435 being the worst one in the same price range: the Gigabyte DS3 P43 version.)
    Am I overlooking something? Would more voltage sort these problems? (I already went a bit overboard just to test)
    Are there settings I'm missing?
    Any help would be greatly appriciated!!!

    Hi Unicron, read ur post and thought id give you some feedback.Im the guy who originally posted the 417fsb wall thread.I beleve these boards with the p43 chipset Do indeed have something going on which limits  the higher fsb speeds seen by p45 series. Id be interested to hear if Any one with a p43 version msi board has achieved speeds beyond 415-417. I know the p45 chipsets have gotten thru the 500fsb barrier.I had tried Every bios available for my p43 neo3-f board and EVERY possible bios setting and yet never got beyond that 417 limitation. Voltages raised in cell menu have No effect on getting thru it. board is strong and stable Up to that point, then 1 mhz beyond there is no post or freezing as it enters desktop.Ultimately after spending 3 weeks intensive trying everything and scouring every forum and msi tech for advice, to no avail, i just gave up on it and returned my board to manufacturer. I purchased another brand of board and went right thru that fsb wall with same hardware and cpu.i was able to achieve 535fsb no problem. I had tried to post "which" board i went with before on this forum but was  censored heavily for trying to do so. I guess such sharing is Not allowed. Moderators take that as promoting "other" manufacturers boards and frown on it.My intent was only to share what i learned and help others. So i have to keep that info to myself sadly.. anyway thats my 2 cents, my name is Paul. good luck !
    Yes, I think we discovered the same thing:
    The MSI P43 Neo boards don't go over 414, 415 or 417mhz FSB.
    Nor do various other brands. I must say I haven't found/read about a P43 board that does. But I guess if you claim there 's such a board, it must exist.
    I'm done looking. Next time I'll buy a higher end board. Low end CPU + Low end board OC isn't a very good idea. I should've gone with a X48 MSI DDR2 board + E9650.

  • MOVED: MSI P43 NEO with Q6600?

    This topic has been moved to Overclockers & Undervolting & Modding Corner.
    https://forum-en.msi.com/index.php?topic=148594.0

    Overclocking means operating a component or a set of components outside their actual specifications.  That means, whenever overclocking is involved, negative consequences (increased heat, signal distorsion, shortened component lifetime, sudden component death) always have to be counted in as a result of overclocking.  Users that do not accept these consequences should not even think about overclocking.  
    Yes, the P43 Neo has a limited voltage regulator/phase modulation architecture which, among other things, does not make it really the best choice for overclocking.  It is a cheap, low budget mainboard with limited capabilities.

  • P43-Neo Strange behaviour with LG IDE/PATA DVD Burner attached

    Hello, I have spent several hours installing an OS on my new MSI P43 Neo-F v1.0 Bios v1.9:
    - 1x 1000 GB SATA HDD Seagate
    - 1x DVD Burner LG IDE/PATA HL-DT-ST_DVDRAM_GSA-H42N Firmware RL01
    - 4GB OCZ Gold
    - MSI RX2600 Graphic Card
    - Bequit! Power Supply 350 Watt
    Trying to boot from the DVD Drive works, but either XP not Vista could make it to the setup screen.
    - Vista stops after some seconds with an unexpected I/O error.
    - XP Setup just crashes and dumps register values.
    Boot from USB memory stick (DVD still attached but no DVD in) lets you enter the setup and select the HDD as intall target. But, if you click "next" it gives you a message that Vista could not verify if a suitable system disk is installed.
    I could only solve the problem by completely disconnecting the GSA-H42N DVD Burner from the IDE/PATA connector.
    I could install Vista now from USB.
    After Vista was installed I reconnected the GSA-H42N DVD Burner to the IDE/PATA connector and could install software etc.
    Anyone being able to comment on this very strange behaviour ?
    In conjunction with other boards I did not encounter issues like this with that LG DVD Burner.
    It has shown that with the MSI P43 Neo F the LG GSA-H42N is unable to boot any CD/DVD. Linux for example stops booting with image crc check error.
    I have now swapped the LG GSA-H42N with an GSA-H10N from my other machine and it can boot any CD/DVD from it - everything runs fine.
    The LG GSA-H42N now runs with my other machine (with an Asrock P43 DE motherboard) also without any problems it can boot any CD/DVD from it
    Thank you,

  • P43 NEO + Intel E8400 - OC Help

    *EDIT* Oops maybe this should be in the OC Forum, don't know how I missed that.
    Does anyone have any suggestions or any bios settings that are working stable at around 3.8 ghz?
    MSI P43 Neo
    Intel E8400 @ 3.0 Ghz C0 stepping
    2 Gigs (2 x 1) Crucial Ballistix (2.2 volt) 800 Mhz
    I have it running at 3.6 Ghz now with the CPU @ 1.3 Volts and the RAM @ 1.9 volts - other settings are auto for now. Any help would be great.

    Best way to go is slowly raise your fsb and monitor temperatures then stress test for system stability, I wouldnt change stock voltages untill your cpu or memory isnt stable and needs more. More volts=more heat so be carefull how much you feed your cpu and ram. Keep in mind when you raise fsb your memory also increases in frequency (and heat) and can only take so much. Also set your fsb-memory ratio in bios to 1:1. What sort of heatsink are you using on your cpu? because overclocking will make it very hot. I had a scythe ninja on my old E6400 which could easily hit 3.2G stable but the heat generated and the noise from the fan having to go full speed drove me up the wall. I have and E8400 now and dont bother overclocking, I learned to appreciate cool and quiet

  • [P43 Neo-F] No Pci-e Frequency option in BIOS??

    Hi..
    I am using a MSI P43 Neo F Board(MS-7519).
    Now I am facing the FSB Wall problem of this board and the only solution I have found is to increase Pci-e frequency to 104 as suggested by the main topic about this problem on this forum. But the problem is that there is no pci-e frequency option in my bios. Bios is latest as confirmed by live update software but there is no such option.
    Can anyone help me on that?why is that I have the same model but not the same options??

    Quote from: Adiel on 13-April-11, 04:02:00
    You have not used P43 Neo F I suppose, that mobo does not go above 400 or 415 fsb, search the internet, its a common problem, and the only solution is the one i posted. But why is that the bios of my mobo does not have this option??
    Its most likely because the parts are not the same and even if they were they wouldn't work the same.
    Like he mentioned already, it works for some and not for others. Its a fickle thing, it isn't a matter of "oh hes better so it works" its more like "his CPU's die isn't as f-ed up as yours is". Something along those lines.

  • Need help guide overclocking newbie msi p43 neo

    Hello i just wanted to ask for guide help tutorial ( no OC experience)  on how to do a mild overclock my cpu e7400 + (msi p43 neo) my main goal is 3.0 Ghz with a 1333 fsb. Im still researching guides but its still a bit complicated. My concerns are on the bios  high incriments on the cpu voltage adjuster i can only adjust with increments of 1.141 next is 1.441 then 1.641 is it too high? i am using the default bios. Im not planning on adjusting my memory its at 800 Mhz
    ATM at the bios i can see my default fsb is at 266 x 10.5 = 2.8 Ghz my plan is adjusting it to 286 x 10.5 = 3.03 Ghz.
    My question is how will i raise the fsb to 1333? by adjusting the fsb on the bios am i only adjusting the cpu clock? and is the cpu voltage same as the vcore( the thing they adjust when OCing ) which i cant locate on the bios only cpu voltage..
    And as a backup plan if all fails when trying to OC flashing bios is the right thinkg to do?
    really srry if this is the wrong place to post. If theres any links(guides) with pics same bios you can give would be a tremendous help. thx

    Hi,
    just a few first comments, so that you don't get onto the wrong track:
    Quote
    by adjusting the fsb on the bios am i only adjusting the cpu clock?
    The FSB Frequency is the base frequency for both the CPU Frequency and the memory frequency.  The CPU Frequency is always calculated like this:
    (real) FSB Clock Speed x CPU Ratio/Mutiplier = CPU Frequency
    The Memory Frequency is adjusted via the FSB/DRAM Ratio Option.  If the FSB Frequency is set to 266 MHz the memory will run @DDR2-800 if the FSB/DRAM Ratio is set to 1:1l5...:
    266 MHz FSB x 1.5 = 400 MHz (= DDR2-800 effectively)
    When you raise the FSB Frequency you have to make sure that the FSB/DRAM Ratio you have set in BIOS will not overclock your memory beyond its specifications.  It is not a good idea to leave the FSB/DRAM Ratio set to "AUTO" when you are overclocking.
    Quote
    My concerns are on the bios  high incriments on the cpu voltage adjuster i can only adjust with increments of 1.141 next is 1.441 then 1.641 is it too high?
    Have you browsed through all the values the BIOS allows you to set in order to check if there are other values available?  Setting the CPU Voltage to 1.441 or 1.641 is not really something you should do.  1.441V is already quite high but 1.641V is definately too much.  Leave the CPU Voltage on AUTO for now and see how far you can get without adjusting the CPU Voltage (check the actual Voltage with CPU-Z).
    Quote
    and is the cpu voltage same as the vcore
    Yes.
    Quote
    my default fsb is at 266 x 10.5 = 2.8 Ghz my plan is adjusting it to 286 x 10.5 = 3.03 Ghz.
    You probably won't need to increase any critical voltage levels for that.  This is a really, really moderate overclock.  Just see what happens if you adjust the FSB Clock Speed to 286 MHz without changing anything else in BIOS (well, keep Spread Spectrum and DOT disabled at all times when you overclock),
    Quote
    And as a backup plan if all fails when trying to OC flashing bios is the right thinkg to do?
    No, that is definately the wrong thing to do.  If the system refuses to start after you changed certain BIOS Options, clear CMOS with main A/C power cable removed from your PSU.  This will erase all settings and make the BIOS prompt you to reset everything.

  • Need help to oc msi p43 neo

    hello all,
    I just got my new computer fresh from the shop:
    cpu - c2d e5200
    cpu fan - arctic cooler freezer pro 7
    mobo - msi p43 neo
    (http://global.msi.com.tw/index.php?func=proddesc&maincat_no=1&prod_no=1484)
    memory - kingston 800mhz 2gb*1 value - I think the timings are 6-6-6-18
    gpu - sapphire radeon 4850 dual slot fansink
    psu - jsp-tech (ezcool) 450w
    hd - wd 640gb
    case - silverstone ps02b with two case fans
    bios version is 1.7
    OS - windows xp sp3
    I want to do a moderate oc on this baby, but I'm afraid since it's my first time. I read a lot from the internet and also the manual but still have several questions.
    1) I understand that in this mobo there is no need to adjust the pci and pci-e bus?
    2) I plan to do a modest oc - raise it only to 3.0ghz. the bios has gray "auto" next to all of the voltages brackets. can I keep it in "auto"?
    does "auto" means stock voltages or will the voltages rise when I'll raise the fsb?
    I don't want to "overvolt" just yet.
    3) I understand that I need to change DOT, c1e, EIST, spread spectrum to "disable". but I want to keep the EIST and c1e for power conservation. will that effect my oc, considering it's a modest one?
    4) is raising the fsb from 200->240 keeping the multiplier 12.5 (240*12.5=3.0ghz) and changing the FSB:DRAM to 1.66 a good option or should i try another one?
    5) is there other items I should change in the bios?
    If there is anything else that you can suggest, pls do. thank you in advance for your kind reply.

    if your going to oc it in 3.0 ghz just raised the fsb 286.. reboot and see if theirs and error..
    dont change anything yet..

  • MSI P43 NEO-F, Q9400, GSkills 4GB DDR2-1066 unstable... help!

    Does anyone have the similar setup or any idea why I can't get the system running at 3.2GHz @ 1600FSB and 4GB @1066MHz ?
    I've ran multiple tests with PRIME95 and Memtest64, and was unsuccessful.
    System actually got through Prime95's small and large FFT test OK, but failed the Blend test. So I'm leaning towards the memory.
    But I got LOTS of errors from Memtest86, while memory set at 1066 @ 5-5-5-15 2.1V
    What voltage should I be tweaking the CPU, NB and SB to get the RAM to pass Memtest?
    I'm not asking much, but it seems these overclocked DDR2-800 RAM aren't that stable at 1066 without tweaking other components. B/C the system definitely wasn't stable with CPU/FSB @ stock speed and RAM set at 5-5-5-15, 1066, 2.1V
    Don't know why they call it DDR2-1066 when it only runs stable at DDR2-800...
    Any advice would help,
    Thanks

    The P45 Memory controller natively supports only DDR2-667 and DDR2-800 modules.  From the point of view of the chipset, DDR2-1066 is beyond specifications.  Also, your memory modules are just DDR2-800 sticks with a permission to overclock, not native DDR2-1066 modules, built to work @1.8V.
    This double overclocking makes a stable system @DDR2-1066 somewhat of a hit & miss situation.
    Do you have options to tweak the DDR Reference Voltage Values in BIOS?
    Nope, I didn't find a DDR Ref Voltage value.
    Hmm , I thought the MSI specs posted would mean the chipsets and mainboard can sustain double overclocking...
    Cause the memory module report on the MSI website actually has my memory set, and results were OK when operating at DDR2-1066.

    These are the drivers you used not the ones from the CD? http://global.msi.com.tw/index.php?func=downloaddetail&type=driver&maincat_no=1&prod_no=1483
    Did you install the chipset drivers before installing the other drivers?
    The sound and Lan drivers on the MSI sight are not the latest available. Realtek has newer ones available. I use these on my P35 Neo2-FR without problems but be warned MSI could have custom drivers that may be different than the ones from Realtek.
    Sound driver 5.10.0.5700 http://www.realtek.com.tw/downloads/downloadsCheck.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false
    Lan driver 5.702.0806.2008 http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false
    I do not think the lan drivers would be a problem but the sound could be.

  • *Solved* MSI P43 Neo-F DPC Latency Issue - Latest BIOS Fix

    Hi, I'd like to avail of the latest BIOS fix for the DPC latency problem on my MSI P43 Neo-F (MS-7519) 1.0.
    I'm currently using BIOS 1.9, I haven't flashed to 1.A yet. Does 1.A include a fix or is there another BIOS that's as up-to-date as 1.9 or 1.A that would have the fix, with any links to download? I'm thinking along the lines of the A7519ICI.1xx series, whatever is the latest.
    Thanks in advance.
    EDIT: I have contacted MSI at http://ocss.msi.com.tw/
    I don't suppose there is any links to the latest A7519ICI.1xx BIOS that I can avail of outside of the private MSI FTP server?

    Thanks all for the advice.
    OK, so here's the story. I couldn't relax with those voltages showing up as they were, so I flashed my BIOS to A7519IMS.1A0 (1.A), which is the latest public release for the P43 Neo-F. I was previously on A7519IMS.190 (1.9) before today.
    When I flashed to A7519ICI.104, I noticed the version number was actually 1.10B4 (which I'm guessing can actually be expressed as 1.AB4 - a beta version for the latest public release, 1.A). The flash to A7519ICI.104 solved the DPC Latency issue, as when I used A7519IMS.190 (1.9) it was spiking.
    There is a happy ending. The flash to A7519IMS.1A0 (1.A) has also shown no spikes in the DPC Latency test. It seems the fix must be present in the latest public release BIOS for the P43 Neo-F after-all!
    This screen-shot was taken just a moment ago, proof that the issue has been resolved without a modified BIOS:
    Hope this helps anyone else out who is using the same motherboard and experiencing the same issues. Just get the latest public BIOS. No hassle!

    Please make sure that your motherboard is in-fact the MSI P43 Neo-F (MS-7519) before you flash the BIOS with any of the ones contained within the link above

  • Help! Is my P43 NEO mobo the problem?

    Forgive me for being a novice. I don't really know what to do.
    I built a new computer with the following
    MSI P43 Neo (MS-7519) BIOS V1.3 (A7519IMS)
    ATI Radeon HD 4830
    2GB OCZ DDRAM2.
    Seagate SATA Hard Drive.
    LG DVD RW.
    Intel E5200
    It blue screened every time I tried to play 3D games, with ATI2DVAG.dll error. I updated all the ATI drivers, but it didn't work.
    So I sent the Radeon card back.
    Worried that the Mobo wasn't compatible with that card, I bought a ATI Radeon HD4850 instead.
    Now I get a ATI3DVAG.dll error whenever I try to play 3D games.
    Are ATI cards just not compatable with this motherboard? Or is it my memory? Or something else? Do I flash the BIOS.
    I'm running WIN XP. I was on Service pack 2, but upgraded to service pack 3 to try and fix the problem.
    Nothing works. That's two cards now, and I still can't play 3D games. It usually crashes within minutes.When the computer boots up and the MSI logo is shown, it makes two beeps. It didn't do this with the last card, but now it does. Does that mean it's the memory?
    Any ideas? I don't know where to go from here.

    Check your memory with memtest86+ and if no errors are found and the system is stable, please update your BIOS to the latest version. >>Use the MSI HQ Forum USB flasher<<
