Benchmarks: Dynamic Overclocking on the P965 Neo-F is a big lie!

I've just upgraded to the 1.5 BIOS and decided to run some benchmarks. What I found was interesting, so I thought I'd share:
I set the DOC function to General, which should give a 15% boost to the FSB when the processor is under heavy load. I wanted to see how much that will improve CPU performance compared to when DOC is disableled.
To test I transcoded an album from the lossless APE format to mp3 using Monkey's Audio and Lame 3.96. I chose this software because it reliably maxes out both of my cores, since Monkey's Audio can be set to do two separate encoding tasks simultaneously: one on each core. Lame itself is assembler optimized to use the processor's fancy vector extensions, ensuring a really maximal CPU load. The command line options I used in Lame are: -V 2 -q 0 --lowpass 19.4 --cwlimit 10.7 --scale 0.99 -mj -b96
Here are the results for my system (E6300, P965 Neo-F BIOS 1.5, GeForce 7600GT):
Standard FSB Clock (266 MHz)       
DOC: Disabeled       
        10:35.17 min
Standard FSB Clock (266 MHz)
DOC: General
        12:01.45 min
Slight FSB Overclock (280 MHz)
DOC: Disabeled
        10:05.15 min
Slight FSB Overclock (280 MHz)
DOC: General
        10:05.39 min
To confirm these results I ran 3DMark05 at the default settings with the FSB set at 280. My scores: 5637 with DOC disabeled, 5628 with DOC on General (+15%).
In other words, Dynamic Overclocking on the P965 Neo-F is hopelessly broken. It doesn't actually improve performance and sometimes it seriously damages it! Can anyone confirm that this is so?

My test results:
Dynamic Overclocking actually UNDERCLOCKS your CPU under load!
But it's more copmlicated still: I just did a lot of testing on my E6300 / Neo-F and here are my numbers:
FSB   
DOC Setting   
CPU Freq. at idle     
CPU Freq. under load

The most shocking thing about the numbers is that at 266FSB, DOC actually underclocks your CPU just when you need it most. This also beautifully explains the performance results I got above. But if you look carefully, DOC seems to work just as it's supposed to when you bump the FSB to 267. Higher than that, though, I haven't found a frequency at which it works correctly. Generally, it underclocks, and underclocks more the lower the "rank" is that you choose. The exception to this is 333, where DOC seems to neither overclock nor underclock.

  • RAM clarification for the P965 Neo F...

    I was constructing my first build today, when I came across an interesting note in the user guide for the P965 Neo F. It stated:
    Important:
    1GB DDRII 800 SDRAM memory module not supported.
    Yet on the MSI site it states (for the P965 Neo F):
    Supports up to 8GB memory size (with DDR2 800, memory only up to 2GB)
    I've bought http://www.newegg.com/Product/Product.asp?Item=N82E16820145590 for this build so I hope I haven't wasted my money...
    Contradictory? 
    Does anyone have the bottom line for this?
    Thanks guys.

    Quote from: NovJoe on 17-August-06, 14:24:00
    It is true that the board only supports up to 2Gb of DDR 800MHz RAMs. I'll let you guys know about whether it is true on the 1GB RAM not supported.
    So... 2Gb of DDRII 800MHz would be supported, but possibly not 1Gb, correct?

  • Would the P965 Neo-F make a good board in a student PC?

    These are the components I had in mind for my sister's new PC:
    Core 2 Duo E6300
    MSI P965 Neo-F
    2x1GB Kingston HyperX KHX6000D2K2 DDR2-750
    Asus 7600GS passively cooled
    430W Seasonic S12-430
    Samsung 80GB HDD SATA
    Samsung DVD Burner SATA
    BenQ FP93VW
    MS-Tech Midi Tower
    She does game a little (Caesar 4 too, so the gfx must have a little juice), but mostly DVD watching, surfing the net, work stuff, encoding to MP3 and so on. Would the Neo-F be worth the extra money compared to the 50€ AsRock solutions?
    Edit: Important question: Does the Neo have any other significant problems then with IDE optical drives? Since both the HDD and DVD Burner are SATA I dont expect any problems on this side.

    Quote from: Streifenkarl on 28-December-06, 14:47:38
    Thanks for your input guys. I think I'll stay with the Neo then!  Which BIOS version should I use then? 1.5 or an earlier one for highest stability?
    Use 1.5 if it works right. Seems BIOS has some issues as beta's are released quite often. That Asrock board wouln't be bad, if you get piece that isn't defect. My Asrock's AGP port was faulty which resulted burned GFX. If you are not using external (PCI/PCIe) hdd controllers you should not hit any problems with this board. I would not suggest flashing beta biosses if you dont have problems.
    Jmicron controller might cause some problems, but they are fixable trought newest drivers I have heard. I am currently running some old beta driver with my 965 neo, as I have been too lazy to update to newest as they seem to work enought. I dont use much IDE drives anyway, only my raid1 backup set is IDE, other stuff is SCSI, which are bit problematic with this board.
    2x 12v lines aren't good If you are using some heavy gfx card, if the rails aren't real powerfull. There was some nice postings on these forums about them. I would prefer PSU with really heavyduty one 12v rail. But if it works, dont do anything ofc.
    Your set is almost like mine, tho I have e6400 and kingston valueram. Im not sure if the mobo keeps RAM at specified speed as I havent found any software that could see the ram clock. Well I can run 325 fsb stable with default voltage, so if the ram clock is not fixed to 333 my KVRs are just good pieces
    Nice to see atlast powerfull cpu that can be cooled even with stock cooler when overclocked, tho I already installed my watercooling as all parts of my computer seems to work.

  • Overclocking problem with P965 NEO

    Hi, i actually have a problem with cpu and memory.
    my settings are:
    MSI P965 NEO
    2x 1Gb Gskill DDR2 800Mhz 4-4-3-5 2.0v
    Core2duo e6300
    zalman 9500CPN
    i  want to overclock the micro, and set the ram to the proper timigns, if i set all to auto, and the FSB to 300Mhz, the ddr speed raises to 473Mhz, and it's not what i like, i just want to reach a 1:1 FSB ratio and increase only cpu FSB not RAM fsb.
    Here i dont have the FSB:DRAM ratio, like i used to have in my asus.
    Ok, going to the point, i want to know how to increase cpu fsb and not the ram mhz. and also put the ram to the full spec.
    the ram is at AUTO and the speed manually to 667 because the problems i found with CPU-Z.
    The SPD reports 400Mhz, 4-4-3-5-24(trc)-2T
    Thanks,

    i want to overclock the cpu without overclocking the ram, is that possible with this motherboard??
    for example: 333Mhz cpu and stay at 800Mhz for ram
    the cpuz is reading actually 379 (i cant remember the exact value, but is around this) for ram when i have set to manual 667 why this happen??? (the cpu is at 300)
    The memory speeds you can select are not absolute but FSB:RAM dividers
    533Mhz equals the 1:1 divider
    667Mhz equals the 4:5 divider
    800Mhz equals the 2:3 divider
    This means if you select 667Mhz RAM in bios you don't force 667Mhz but you select a FSB:RAM ratio of 4:5
    At stock FSB of 266Mhz this makes : 266 / 4 = 66.5 * 5 = 333 Mhz (666 Mhz DDR) wich is the 667Mhz you select.
    However, if you change FSB the RAM speed changes along with it.
    So, for your 300Mhz this makes :  300 / 4 = 75 * 5 = 375 Mhz  wich is +- the 379 Mhz cpuZ reads.
    If you want 333Mhz fsb and ram @ 800 select 667Mhz RAM in bios and set FSB to 333Mhz, also enter RAM timings manually.
    This will result in 333 / 4 = 83.25 * 5 = 416 Mhz (832 Mhz DDR) for ram - The gskill should be able to take this mild 32Mhz overclock.
    The board might not make it to 333Mhz tho - It's a budget board wich overclocks poorly.

  • Overclocking E4300 using P965 NEO

    Hi Fellas. Finally, got this system running and here are my experiences, so far:
    1) This board is soooo limited, the maximum FSB which is there in the BIOS is 265MHz.
    2) No TRUE 1:1 FSB/RAM ratio because the lowest RAM speed it supports is 266MHz while the CPU is stuck at 200MHz (800 strap).
    Managed an overclock of 250MHz so far (2.25GHz haven't tried more).
    The best part is that I was able to O/C HIGHER on an INTEL (946GZIS) board where I got this chip to 2.4GHz using Clockgen! haha can you beat that? I hope they can do something with the BIOS, otherwise this is sucky-sucky. I hope MSI realizes that the E4300 is one of THE best chips to overclock and that this board doesn't do it much justice.
    In the meantime, would appreciate it if others using a similar configuration could share their experiences too.
    Thanks.

    I too bought an e4300 together with a P965 Neo. Same results here: absolute limit of 250mhz FSB.
    So I mailed MSI support.. and they sent me a bios update: the still unreleased 1.7. So I flashed the bios, hoping it would fix the problem.
    But no. Nothing. Not even a minor change. I guess they haven't fixed the strap issue that EagleDM is talking about. 
    So I went back to the store, and found out that changing my MoBo is difficult and costly. Has to do with vista or something. I'm no expert.
    To tell you the truth... I might even consider changing it anyway. I've read reviews of ppl overclocking the e4300 past 3ghz. And I'm stuck at 2.2. Even with my brand new Zalman CNSP9500 cooler, which I regret buying now. Stressed CPU temps below 40c are not exactly optimal imho.
    So don't get your hopes up for the 1.7 bios upgrade, guys. I'm very sorry to have to tell you this.
    *edit* Mmm by upping some voltages (RAM) I was able to get past the wall of 250. got it to 265mhz fsb now. Orthos has been running for some time now on blended test.. I have no idea wether or not it was the update, or my own noobness. Anyway, I'm not even gonna try getting past 265 now. I'm way to happy for another bios reset. I guess you guys just have to bug MSI for 1.7 and try it out yourselves :-)

    Thats right, as 10acjed said
    (2x) 1 GB DDR2-800 DDR2 SDRAM (6-6-6-18 @ 400Mhz) (5-5-5-15 @ 333Mhz) (4-4-4-12 @ 266Mhz )
    I can also choose 800 Mhz like the picture of his, but the adjusted dram frequency differs and 800 will result in like ~999.
    Btw the dram Mhz is on generally on [auto], but that is the same as 800.
    So I set it to 667, So the adjusted dram freq will be around 830.
    that could be your problem right there. Is that when you are running at 300 FSB??
    Try it at 533 and see what happens... If it is at 830 when set to 667 and you try and raise the cpu  higher its also raising the ram higher, probably causing an issue..
    I am still pretty sure you are hitting a wall with that board, its just not a great overclocking board. I am extremely disappointed with my NEO-F as far as overclocking goes. But its been running stable for about 3 years now so its a good board....
    If all else fails run it at 300 - 320 (as high as you can get stable) and put the ram at 667 so it runs around 830, ou will have a nice moderate OC...

  • [AMD] Whats the best BIOS for overclocking on the K8N Neo-2 Platinum

    any one know which one is best.
    thanks

    I have no idea what biosversion that is the best in general for OC the K8N Neo2 P.
    I use 1.5 and it´s the only version I´ve used.
    I believe not many people have tested OC potential for all 6 versions 1.0 - 1.5.
    ( even more if you include the beta´s).
    I would say OC potential depends more of what hardware you are going to use.
    Good RAM and a good CPU stepping are in most cases more important then biosversions.

  • AnandTech suggest MSI P965 Neo-F as midrange system board choice

    See latest 'buyers guide' at AnandTech
    http://www.anandtech.com/guides/showdoc.aspx?i=2839&p=3
    It needs some exposure. I never see the P965 Neo get a mention anywhere as a choice for Core 2 Duo.....

    I am an owner of MSI's P965 Neo-F and though my computer is finally running well, I'd hesitate to recommend the board. It was obviously a rushed job, and far too many people are having problems with the JMicron controllers for the drives. I still think it's a miracle that I got this thing running! Most of the complaints you will see here are about the serious limitations on overclocking: yes, they are serious, and also be advised that "dynamic overclocking" is hopelessly broken.
    Anyway, right now you'd be crazy to buy any chip besides a Core2, and the 965 chipset seems like the a good partner for it. However, I don't think MSI's Neo-F is a very good home for that capable chipset.

  • P965 Neo-F JMicron IDE concerns

    I've always been a big MSI fan and I'd like to build a sytem with a core 2 duo and the P965 Neo-F.  However, I've really been scared away by all of the reported difficulties with the JMicron controller.  I will have one SATA hard drive and IDE opticals.  My question is, have issues with the controller been resolved?  Is it possible to get fast DVD read/write speeds with IDE opticals?  Is there a method to get things to work properly?  Thank you.
    DeeJay

    Hello,
    I to have an MSI P965 Neo-F, from the day I had it and put my rig together I have had NOT one single problem with it at all, my dvdrw was set as master and plugged into the ide connector, my sata hard drive was plugged directly into the purple sata port. I DID NOT install any raid or scsi drivers whilst installing winxp, it installed with no input bar the product code and keyboard setup. I then installed all the drivers that came with the setup cd, which includes the Jmicron drivers. Both xp & drivers took about 25 mins. Once done everything was working fine NO problems or issues, no nothing, even after I updated the drivers using liveupdate still no issues at all.
    I'v read that people have had trouble burning cds/dvds, low read speeds, etc... I didn't fiddle with anything in the bios prior to installing xp and I'v had no trouble whatso ever.
    I think that this motherboard is tidy, it runs smoothly with no glitches, the overclocking I think is sweet enough without making major changes to your internal cooling. Reading all the bad reviews is enough to put anyone off, but not many people write reviews about how good this motherboard is, so here i am.
    MSI P965 Neo-F is a dam fine motherboard. It works solidly and is one of the most stable MB's on the market. If people try not to fiddle too much with bios settings, that includes bets bios flashing, and everything before they set it up, then I think they would be more good reviews.

  • MSI P965 Neo-F (MS-7235) problem booting from USB flash drive

    Hi, all!
    I was wondering if someone can help me. I am trying to install Windows 7 x64 on my 320GB HDD that is connected to my MSI P965 Neo-F (MS-7235) mobo (The CPU is a Core2Duo 6600 with 6GB of RAM). I created a bootable USB 8GB flash drive using Microsoft's "Windows 7 DVD USB Download Tool" and bootsect.exe (Needed to create a boot sector on the USB drive) from the MS store. I successfully tested the resulting bootable USB drive using freeware MobaLiveCD (Sorry, you'll have to Google "mobalivecd" since this forum doesn't seem to allow external links) running under Windows XP SP3 x86 (32bit). Under MobaLive's QEMU, Windows 7 setup loaded its files and produced an error message basically saying that it could not install Windows 7 x64 under an x86 OS (No surprise there since QEMU is emulating a 32bit processor - The point is that the bootable USB drive I created works).
    I then went into my mobo's CMOS and under Advanced BIOS Features -> Boot Sequence -> 1st Boot Device, set the value to "USB-HDD" and rebooted my machine. The USB drive probably was not detected by the mobo under that setting because it proceeded to boot from my HDD which is the 2nd Boot Device. I repeated the same process using each one of the  four USB ports in the rear of the mobo (I don't have the optional USB panel that the MSI users manual mentions) to no avail. I also tried setting the 1st Boot Device to "USB-FDD" and repeated the process for each USB port but the mobo still will not boot from the USB drive (It does not recognize it). When I set the 1st Boot Device to "USB-ZIP" and rebooted, the mobo hangs after "Verifying DMI Pool Data ..." which is no surprise since I am not using a USB ZIP drive but a USB flash drive. It appears that under that setting, it recognizes that there is a USB device attached but it is expecting a response (From a USB ZIP drive). I had no idea it would be this frustrating to boot from a USB flash drive! If anyone knows how to make this mobo boot from a USB flash drive, please let me know. Any assistance would be greatly appreciated. Thanks!

    The P965 Neo motherboard is 8 years old, so don't expect miracles. .... You need to format the USB stick in the proper way. You may use this utility to do it: hxxp://www.prime-expert.com/flashboot/ Also, it's a good idea to use the first (USB0) connector (controlled by Intel ICH8) for the USB flash drive. Good luck.
    Thank You for your fast response, RemusM!
    I'm not looking for a miracle. I'm just looking for a mobo that does what it is supposed to do: Allow me to boot from a USB flash drive (I don't think that is too much to ask for even from a board that was made in 2006)!
    Thanks for recommending FlashBoot. I see under their "Why FlashBoot" section that it "... does not shift to user the burden of choice between "USB-ZIP" and "USB-HDD" at format time and proper BIOS setup at boot time. ... and every USB disk is formatted in such way that it will work in every environment properly, regardless of current BIOS setting.", so I will give it a try and let you know about the results afterwards.

  • P965 Neo-F audio jacks not working.

    I've been having serious issues with the audio jacks on the P965 Neo-F board.  I have actually tried two boards, convinced the first board was defective since my speakers worked fine on other computers.  On both the current board and the last board, I did a complete clean XP install, formatting my hard drives and installing the latest RealTek HD drivers (5.10.0.5404 dated 4/23/2007, from MSI).  The first board never so much as peeped, while the board I have now has made some sounds, although I honestly don't know why.  On this board, I had a set of Altic Lansing 2.1 speakers, but because the speakers would pop and make static noises every now and again, generally only if I bumped one of the small stereo speakers or wiggled the cords on the back of it, I thought perhaps the problem was the speakers being old.
    On the current board, I tested a monitor that has speakers in it, and there was no sound.  RealTek's sound manager, which I have installed, did not recognize that there was anything plugged into the jacks even though I had a line in, microphone, and line out plugged in.  When it did recognize the lino out, it also recognized the microphone.  However, it only recognized them for no more than a minute.  The new speakers (also Altec Lansing 2.1) made one squeak for less than a second; other than that, there has been no sound at all.
    I've tried several different RealTek HD drivers from MSI, Microsoft, and RealTek, but none have made any difference.  I've enabled and disabled only to re-enable the audio device through BIOS with no success.  I've checked the volume, DxDiag, and played music--Winamp and iTunes are both making sound, but no sound is coming out.
    I'm pretty much out of ideas here.  The only thing I can think to do is get a sound card, but I don't see why I should have to do that when I'm not an audiophile and the board jacks should suit me fine.  I am quite at my wit's end with this, and would appreciate any help I can get.

    Quote
    It recognizes that I pluged something into the microphone jack but can't get the microne to work.
    This problem usually has to do with the fact that the computer case used, or to be more precise: its front panel audio connectors are not fully Intel HD Audio compliant.  Disable the Automatic Front Panel Jack Detection Function in the Realtek HD Audio Manager and retry.
    If your mic still does not work as it should, browse through the Realtek Program Folder and look for an executeable file named "miccal.exe".  Run it to calibrate your microphone.  Also, enable "Microphone boost" in the Mixer-tab of the Realtek configuration program. The top half part of the mixer Tab ("Playback") can be scrolled to the left via <> buttons.  Scroll left and localize the input jack your mic is plugged into (example:  "Rear Pink In").  Click on the Options button and enable microphone boost.
    Quote
    When I go into the mixer settings I can't adjust adjust any of the inputs - cd, mic, line etc. Although it shows places for a sliding volume adjusters but doesn't show a slider to be able to adjust the volumes of the inputs.
    That is totally normal and not a problem.  It is basically a limitation of the Realtek HD Audio Driver in combination with Windows XP.  It has nothing to do with the board.  Here is an Asus-example:
    There is nothing wrong here.  If you scroll through that output devices/jacks in the Mixer tab of the Realtek HD Audio Manager, you will find that you can adjust the input/output volume for each audio jack individually.  Doesn't make sense to adjust input volume in the output section?  Well, ask Realtek which genius designed the interface and ask him personally.   

  • MSI P965 Neo board failure ?

    I have the P965 Neo board running perfect for two years, for a few weeks ago the system didn't startup, a long beep sound came from the MB. I opened the case, checked connectors etc. and replaced the memory modules. After that the system runs ok, no problem occurs for almost three weeks.
    For a few days ago, out of the blue,  the system didn't startup: error message: "WARNING Have option ROM can not be invoke (Vendor ID: 10Ech, Device ID:8167h)"
    I reset the system and it passes the POST, the WINDOWS XP splash screen shows up but after a few seconds the blue progress bar stops.
    I reset the system again and now the WINDOWS XP splash screen stays fade out, no progress bar
    I reset the system several times, after a few times the system normally boots up and is ok.
    I tested the HD with Speedfan Smart utility and it is found ok.  Also no virus etc is found. I checked the device manager, no driver problems.
    Yesterday the system had the same problems (XP boot blue progress bar stops, sometimes the progress is very slow) but after a few restarts the system boots normal and is ok.
    Tonight, after I had opened the case to measure the voltages, I startup the system but no problem occurs. The 12V and 5V are ok
    I think I have a hardware problem but I'm doubt what hardware (MB,RAM,PSU,processor) causing this kind of problems.
    Can you help me ?
    thanks,
    Herman

    Clear CMOS and try booting the system again.
    Was the system like this from Day 1 or this only happens after something has been done?
    Thks NovJoe ....
    The system had run without any problem for more than 2 years.
    I presume I have a connection problem on the MOBO or other hardware. If I place the PC case in the cabinet under my desk, the problem occurs. If I have the PC on the floor there is not any problem. It also happens only when the PC is cold.
    I asked my hardware supplier, he suggested to test the hardware with a special self booting hardware test CD. It will cost 40 euro. I searched for such a CD on internet but didn't find one special for MSI boards. Do you know where I can get such a CD ?
