K8N Neo4 Plat, SATA2 and Shutdown Problem...

Hi, new here.
Glad to have a board like this to ask some questions to other users.
Purchased the board a few months ago, and apart from the noisy NB fan, all was ok.
Then recently bought a 200GB SATA2 drive (see specs in signature).
Since its installation, but not before, I've had a systematic shutdown and reboot problem: the shutdown proceeds as usual, the "Windows is shutting down" and "Saving preferences" dialogs come and then disapear... but then only the mouse cursor is left on blank screen (it can even be moved), and the shutdown process doesn't go further; after several minutes I just shut it down with the power button.
The event logs don't show anything problematic.
A few more details:
My drivers are the most recent (official) from MSI.
I've installed Win2000 in ACPI Uniprocessor PC Mode.
The drive is recognized as a sata2 device.
I use the SATA#1 (nVidia) port.
I've put the pagefile on that drive.
Nothing is overclocked, CoreCenter is disabled.
I've installed the UPH Clean tool from Microsoft, but that didn't help.
Memory passed lengthy memtest session.
Strangely, the SATA2 drive appears in the "Unplug or Eject Hardware" list in the tray, usually reserved for connectable devices (USB, etc): is that normal? (I'm new to sata drives)
I've searched this board for similar problems, but they seemed to be mostly in RAID context, which isn't the case for my system.
Any idea what might be the problem ? Anyone experienced the same problem (non-RAID) ?
Apart from above problem, drive seems to function normally.
Thanks in advance.

@gerasimatos: maybe he used xsetup? didn't try it yet, will have a look. In the BIOS, all RAID-related settings are disabled.
@kakarocht: the power managment in the BIOS has the default settings.
Will try to change a few params here and there.
I have not tried yet other ports on nVidia controllers.
I may eventually try the Sil ports, in last resorts, BUT I would prefer to solve this issue with nVidia ports first (I think at the price we pay these things we shouldn't be precluded from half the SATA ports! )
I tried to list as much relevant specs as I could in the signature and post. Here are others:
memory used at 2.5-3-3-7 1T setting (memtest passed)
regular ps/2 keyboard
ms intellimouse (using ps/2 connection)
the asus graphic card used in single monitor mode (recent drivers)
when I said "CoreCenter" disabled above, meant "Cool'n'Quiet" disabled (not stressing system yet, so 'cool' isn't an issue; as for quiet, if the board can't lower the NB fan speed, it's a non-issue!!!)
using on-board sound-card
using onboard gigabit port for internet connection
no other peripherals installed presently
hard drives temps stay under 40 C (not stressing system lately)
I removed DigiCell and CoreCenter from loading at startup (don't need them for now)
closing firewall (zonelalarm) before shutdown didn't help (although didn't try unloading the service yet)
... what else might be of help to list?...
Again, I'd like to know if it's normal that a SATA2 hd drive appear in the "Unplug and Eject Hardware" tray icon list; I wasn't expecting that, but I'm new to this kind of connection.

K8N Neo4 Plat NB fan Speed problems

Hey,
I recently bought this system (see signature), and just today the NB fan started going haywire… I’ve done some searching on these forums and it appears im not the only one that is having problems with the K8N Neo4 Platinum chipset cooler.
CnQ reports RPM numbers in the upper 7000 (usually around 7500 RPM), and the noise it generates is intolerable.
I’ve tried to manually set the NB fan speeds via the recommended SpeedFan application, but to no prevail.
Can it really be that there are no solutions to this problem other than replacing the chipset fan?
If that is so MSI should really consider selling future revisions of the motherboard with a different fan, or, enable control of the NB fan voltage.
I really hope someone can help with this, all the other topics didn’t provide any other solution than to replace the fan… but the last entry to these discussions was back in May, so I hope additional solutions may have surfaced.
Thanks

It wont go any faster then present though.
In my case the fanmate with setting wide open produces a little less rpm on the northbridge then without this device.
the fan will spin faster if the voltage applied to the fan is higher, and slower if the voltage is lower. so if you supply the same voltage (basicaly use the same connector on the mobo) and keep the fan mate to full, the fan will spin a little bit slower since the fan mate already acts like a resistor, even if set at full speed.

K8N Neo2 Plat IDE and SATA problems

Last night I was able to install XP onto a Raid 0 set up with 2x36 GB Raptors. (These were on Sata3/4 as I had heard about oc problems with the other Sata ports). No other drives were installed. After installing XP I decided to shut down and add a 40 gb IDE drive that had several things I needed (like programs!) and also installed another Sata drive, this time it was on Sata 2.
(I did discover that the system will not boot if there are drives on IDE2 (optical drives) while IDE1 is empty... so moved the optical drives to IDE1)
After installing the two extra drives I booted up. Fine. But when I went to change a display setting, got BSOD.
So went back and tried again to setup the Raid 0 and install XP. Even without the extra drives, no luck.
After third attempt, I gave up on Raid and just installed XP onto one of the Raptors that was on either Sata 3 or 4. No other HD's installed. It worked.
Then went back and tried to stick that 40gb IDE in and the 80gb Sata.
Ack! No boot and got a hal.dll error. Googled that and I guess it has some sort of virus or whatever. Figures. Okay. Disconnect both the 40 and 80 and it boots.
This time tried just with the SATA 80 (in addition to boot drives). No luck. Get an error saying that it can't find boot drive or something like that.
Next tried to move the Sata cables around, putting the true boot drive onto Sata1. Of course it didn't work and NOW (after putting the cables back the way they were for the boot drive i.e. Sata3/4 (not sure which) the system will not boot at all giving the "no system disk" error.
If I had hair to pull out it would be gone.
When looking into the BIOS I see that the 2 36gb Rap's are on IDE channel 5 and 6.
I don't know what BIOS I am running.
Is there some sort of "priority" that XP assigns to various IDE channels? Sata ports? At this point I could care less about overclocking, so am thinking of putting the 2 36gb Rap's on Sata 1/2 and starting from scratch trying to install XP on Raid 0 (yes, I installed the Raid drivers from a floppy). Shouldn't that work? I might end up just using the 80 gb SATA drive as the boot drive and not using the Raptors.
Someone please save me!

Be interested how stable your raid setup stays? See my post https://forum-en.msi.com/index.php?topic=94536.new#new
Been driving me crazy. System stays stable, now I've ditched raid, as long as the other Raptor doesn't have XP on it. It seemed that XP was seeing two disks instead of one at close down when I had raid installed and writing to just one - very weird - which blew the array. Never had these problems with Promise Sata Raid. I suspect, like many others, that NV have a driver problem.
You know... you didn't really HAVE to share this info with me!!
Let's hope it stays stable. If not, then I will get a different Raid controller.
Along with backing up my data on that array as soon as I can!

SATA hard drive problems with k8n neo4 plat

Helo , I am hoping someone can help me with this. I have read Fafner's thread on installing a sata hard drive on the neo4 mb but the only utility program I found on wd site is called " lifeguard11 for windows". Is this the right utility to use to partion my hard drive? I burned it to a cd and and my computer will post but will not boot from that cd. I have followed the instructions that came with the mb and used the floppys at F6 but it won't countinue to install windows after that.
Also I'm not sure how to enable sata in the bios. Do I go to integrated peripherals/sata devices config. and at the top of the screen it say's RAID Enable. Do I enable that and then enable sata1 raid? I am only using one hard drive. Thanks for help you can give.

My system is similar to yours, if your just using the one Raptor you don't need any special drivers, your mother board will detect the Raptor with out any special settings. I hooked my Raptor up to SATA 1 (look on pg 2-2 of your book for the location) If your only planing on installing one operating system on your hard drive, such as windows XP pro, Windows will format and partition the drive for you.
If your having problems booting from a CD make sure you change the boot order in the BIOS (under advanced bios features pg. 3-8 of your manual) so that CD is before HD. For example, mine is set up for: First boot device = Floppy drive, Second boot device = CD Rom, Third boot device = hard drive, and etcetera. if your using more than one hard drive such as an IDE drive make sure you set the "hard disk boot priority" on the same page to the hard drive you want to boot from.
Once that is done put your Windows CD in the CD drive and reboot, Windows will guide you through the rest.

K8N Neo4 Plat and 3500+ venice?

I have searched this but am more confused now than before. I am thinking of upgrading to the 3500+ venice with a K8N Neo4 Plat or sli is this a good combo.Tiger Direct has the Plat. and the SLI for the same price $149. Does this cpu work better with one or the other board?

i have the sli/plat and the 3500+ venice and it seems to work well with the 3.4 bios dont know about the plat but its basically the same. just my input

K8N Neo4 Plat (non sli) Device manager error !

guys:
need some help. as stated,, have just received a k8n neo4 plat (non sli). just installed win xp pro (many thanx to people on forum for good tips on coming up clean). i have 1 problem, i have 1 item in device manager banged out (!), its a "PCI Memory Controller. i have nothing on mobo cept 1 6600 gt video card, 1 stick mushkin 3200 dram, i maxtor 200gb sata hard drive. searched on msi's site for this driver and can't find it. any ideas on what i'm missing?? sorry for not having rest of sys specs in sig but just got this puter up and running and i would like to get this driver installed before i pack it in for night. thanx for any help on this one.

igmox:
thanx!!! standalone drivers did the trick. when i was puttin this puter together i downloaded the standalone drivers and extracted them onto a cd. when i booted, anything in device mangler that was banged out, i updated the drivers via the cd. this time i downloaded the standalone drivers, ran the exe (unchecked the ide drivers, since i'm gonna try and run 6 dvd burners) and viola,, driver found.

Difference between K8N Neo4 Platinum/SLI and K8N-SLI Platinum

Hey guys.... I have one question and i hope you can help me.
I'm about to get an MSI SLI Platinum motherboard, but it seems that there are two versions, the K8N Neo4 Platinum/SLI and the K8N-SLI Platinum.
What is the real difference between them? As i can see in the manual, the Neo4 version has the additional SATA2 and Gbit LAN controller.
Anyone: Does your K8N-SLI board have 4 or 6 SATA2 ports? and 1 or 2 LANs?
At this picture http://www.midtdata.dk/asp/index.asp?varernr=K8N-SLI-PLAT&goto=productinfo&mainfunc=link I can see that there are 6 blue SATA connectors (lower right corner), and 2 LAN ports left to the LPT port... But the description says 4 SATA and 1 LAN, and so says the manual.
To all owners of this mobo: Does this picture look like your K8N-SLI Platinum or does it look like your K8N Neo4 Platinum/SLI ?

K8N NEO4 Plat - setup

this is my new build -

AMD Athlon 64 3700 San Diego Core
Antec True Power 2.0 550W PSU
2 x 6600GT BFG SLI-Cards

and other various items that need not be listed.....................
Anyways, i have the RAM running at 2/3/2 latencies at 2.85 Volts and I am looking to get more UMPH! out of it but Mushkin says i need more voltage. Is there a way of upping the voltage on this mobo? My previous mobo, a DFI board had an insane amount of voltage available but the board itself was a PAIN IN THE REAR! so it has been replaced, thankfully. Anyways, is there a revised BIOS that provides more volatage and isnt flakey? I would rpefer something that is not a BETA version, BETA=PROBLEMS. has anyone compiled a custom BIOS by making some revisions to an exisiting tested BIOS?

Well, I don't think there is, I've been reading about this, since I'm getting one of these Mobo's...
Either go for the beta bios or mod the official bios to allow the same amount of Vdimm as the beta, and flash with that...or google for some of Tictac's, Oscar_Wu's, etc modded BIOS'.
Maybe you can contact one of those guys over @ XtremeSystems.org and they may be able to hook you up.
BTW: The OCZ DDR Booster does NOT work with the Neo4 series.

K8N Neo4 Plat (MS-7125) v.1.D user manual/settings?

Since I flashed my PCB 1.0 K8N Neo4 Plat to BIOS 1.D a couple of years ago I've been sort've just winging it with the many increased settings that 1.D added. I know all of the basics like clock and DRAM settings but the rest I'm clueless about. Is there any official or unofficial post or document out there that explains these settings and what their optimal values should be?
TIA!

Max OC was 3203 but for everyday I had it at 3080 for a couple of months and then I got some different RAM and had some problems with it and have it backed down to 2640 (240x11), HT link is at x3 (720) but would be okay at x4 which would put HT at 960 for the OC I have now and I went back to my old RAM. I haven't yet worked it back up to OC I had before. Neo 4-F & Plat. PCB 1.0 seem to OC better than other versions of K8N which seem to max out at about 2700.
Keep HT link below 1000, if you OC it enough that it goes over drop it to the next lower setting. Your 2500 clock is no problem at stock voltage and you would need to OC quite a bit higher for any need to raise voltage. Lets see what setting you have questions about before I go too far here.

K8N Neo4 Plat. boot delay with Canon MP390

Hi everyone!
My problem is the following:
My K8N Neo4 Plat. based computer got a huge delay (5mins!) on POST at boot (right after CPU name listing) when my Canon MP390 multifuntion USB printer is connected. I already know its caused by a conflict between the printer's card reader and the mobo, something maybe related to the mobo trying to boot on the card reader. Could be something else, but for now that's the only explanation i could find.
I red all post here concerning USB boot problems (or delays) and tried everything i could and red without results
Things that have been done (and much more!) :
- Flashed to latest v1.5 BIOS
- Disabled booting to other devices in BIOS leaving only floppy, cdrom and HD as bootable devices
- Disabled support for USB KB/storage devices in BIOS
- Unplugged Mitsumi floppy/cardreader combo drive (USB internal)
- Unplugged front panel USB and D-Bracket2
- 2 days of various tests with other computers, printers, psu, USB devices I had in store
I'm about to give up on this one! .. Anyone got ideas other than buying a new multifuntion printer? Could it be a defective mobo?
Thanks!
Rivendell
Computer specs are:
Athlon64 4000+, MSI K8N Neo4 Plat.
2x512MB PC3200 (OCZ 1GB KIT PN: OCZ4001024PDC-K)
Sapphire X850XT PCI-E 256MB, WD Raptor 74GB SATA
Thermaltake Silent Power 480w PSU, NEC 16X DVD-+RW
Mitsumi floppy/cardreader combo drive (unplugged for testing purpose)

It might be related with BIOS. The BIOS 1.65 seems to resolve the quick boot issue. You can get it from MSI to try it.

Max stable CPU voltage supported by K8n Neo4 Plat.?

My vcore voltage fluctuates between 1.44v and 1.50v. In the bios I have 1.42+6.6%(see my sig). I have ran prime 95 for 24h stable, but recently I tried OCCT(a french program). The first test ran for 30min OK, the torture test froze my computer within an hour or two. My question is what is Max stable CPU voltage supported by K8n Neo4 Plat.?Because obviously when the mobo drops it to 1.44 it IS NOT ENOUGH. Difference of .06v obviously is critical for the stability. Anyway it should be 1.425+6.6%=1.519 which is nowhere near 1.44. I currently run at 36-38C idle and 45C under load. Is it a bios problem? I use 1.6 bios and I don't have any problems whatsoever.
Any opinions appreciated.
BTW tried to raise the mobo voltage at 1.55(1.50 default) but seems that there is no difference.
BIOS shows my voltages as follows:
+3.3v=3.12 to 3.15 mostly stays at 3.14 pc wizard shows 3.14, core center shows 3.22
+5.5v=4.96 to 4.99
+12v =11.96 to 12.22 core center shows 11.96, pc wizard shows 12.22

dont blame MSI for your financial situations. If you could afford the proper hardware then you wouldnt need to overclock and such. JMO.
I can afford the proper hardware. In fact, I bought a DFI Lanparty nF4 SLI DR to replace the defective K8N Neo4 SLI board.
As soon as the new K8N board comes back from RMA, I figure to sell it - say half off. I think for something that may or may not work as advertised, half price is fair.
And speaking of processors, these Venice chips are really phenomenal - they're just like (or maybe even better than) the good old XP1700 JIUHB chips. I still have one of those - and strangely enough, it's still running - in an MSI K7T Turbo 2 board (KT133A). That JIUHB served me well - it'd do a 500MHz overclock with no strain at all. If I had water cooling, I bet I coulda got 1 GHz out of it.
The two Venice 3200 processors I have both seem to be really good overclockers. The one that was in the rig I RMA'd is the best - right now in the new Lanparty board, I've got it running at 2.5 GHz (1:1 @ 250 MHz) with about 1.55 volts. It's idling at about 30c and only runs at about 44c under load - and the AS5 hasn't even cured yet!
That chip is gonna be one helluva overclocker!
I'll let it run at 2.5 GHz for another week or so till the AS5 has cured, then I'll see just how far I can go (without the temps getting too high). The way it's gone from this point, I think 2.7 GHz is very reasonable for a goal.
And as I think newbie222 pointed out, as long as the temps are kept reasonable, there is no actual risk to the processor.
The point I was making is that with my old, defective K8N, that would not have been possible - BECAUSE THE BOARD WAS DEFECTIVE. It was defective because the vcore did not operate up to spec (wouldn't go as high as it was advertised to) and because of the voltage fluctuations.
How would you feel if you bought a new car that was advertised as getting 24 MPG highway and it only got 17 MPG? Or if you ordered Comcast's 8 Mb/s downstream Gold Tier and only got 6 Mb/s downstream? Or if you ordered a 102 channel cable package that turned out to only have 88 channels?
It's all the same exact, precise thing.
If MSI advertises you can get a vcore of 1.7> volts then you fer damned sure better be able to get it.
The main reason people buy boards like the K8N is to overclock - it's the "enthusiast" community that the board is targeted to.
I find it hard to believe anyone would even want to buy one of these boards and not overclock. What's the point? If all someone wants is something that will run at stock speeds, then they oughta save a few bucks and buy a Dell or whatever.

K8N Neo4 Plat: Choosing new PSU & Want Your 2 cents B/T my Choices! :)

Read the PSU sticky and have nailed down my choices to a few, which I'd like your opinions on, if anyone thinks one looks better over the other. Here's the rig:
K8N Neo4 Plat
AMD Athlon 64 FX
2GB RAM (XP Home)
(3) 160GB SATA II drives, non-RAID
7950 GT Fanless (no SLI needed)
Plextor 716-A DVDR
Floppy
SB Live! Drive
Xion 600w (+3v 35a / +5v 53a / +12v1 22a / +12v2 22a / +5vbs 3a)
Xion has been a good PSU but is sounding tired at boot until it warms, and frankly, it's only been 2 yrs or so since I got it. After reading the PSU sticky, I narrowed it down to these three:
Silverstone 600w dual rail: http://www.newegg.com/Product/Product.aspx?Item=N82E16817163109
Corsair 550w single rail: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004
OCZ 550w dual rail: http://www.newegg.com/Product/Product.aspx?Item=N82E16817341022
A couple of these happen to be modular, and I saw the sticky recommended against them due to poor connections, etc. Is this still a general consensus? I won't be in and out of the rig anymore.... I built it a few years ago and use my laptop more, actually. It's become a second computer, so frankly I'm not too worried about connections coming loose. If I shove em in good once and leave it, I imagine it will be alright. But neither do I care if it is modular.... just looking for which one looks like it would serve the rig better. All opinions are welcome! Thanks!

Thanks Frankenputer and Henry, I was just coming back to add the P&C Silencer 610: http://www.newegg.com/Product/Product.aspx?Item=N82E16817703005 as a possible choice, and saw you suggested it! That beefy rail looks good and it's advertised as being particularly silent which is very important to me. (One of the reasons I find myself using my laptop more is because it's so quiet.) I won't be adding to the desktop rig anytime soon... it's serving my purposes as is. And though I agree I could probably get by with the 450VX, for 10 bucks more, I might as well get the 550W for a little more peace of mind.
So between the Cosair 550W and the P&C 610W, which do you think would be quieter? I'm concerned that the P&C only has an 80mm fan and although they make a big deal about their "silent technology" it doesn't say anything about the fan having ball bearings. The Cosair has a nice large 120mm fan, (larger fans can spin slower [making less noise] while moving more air), which is what I am used to in a PSU, and it is a double ball bearing fan, so it should be pretty darn quiet. If either PSU would serve the rig just as well, then silence is the next most important factor to me, even more than warranty. I'd just as soon replace a quieter PSU more often, than have a noisier one that lasts forever.

Confused - whats the difference between K8N Neo4 SLI Platinum and Diamond??

MSI web page says the Diamond has:
"Silicon Image's SATA RAID supports another 2 SATA II ports. Transfer rate is up to 300MB/s."
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=638
their Platinum page doesn't list the Silicone Image raid as a feature on the Platinum.
I have K8N Neo4/SLI Platinum and it has the Silicone Image raid - I'm using it now.
Can anyone explain this?
Another question: for both boards it shows: "NV RAID (Software) - - RAID function available for ATA133 + SATA HD drives or 2 SATA HD"
How can the Raid fuction work for ATA133 drives since the cables for SATA and PATA are different? What do the mean Raid for 133?
Thanks!!!

Clock problem and shutdown problem! Are they related?

Having a problem with my Dual 2 GHz Power Mac G5
A few days ago I noticed that my clock was not showing in the menu bar in the upper right corner of my desktop.
I went into System Preferences and went to Date & Time. Under the clock tab “Show Date and Time in Menu Bar” the box was not checked off. I checked it off and went to the “Date and Time” tab. The date and time was correct. I then checked the box “Click the lock to prevent further changes” to lock it. The date and time did not show up in the menu bar. I then went back to the tab “Show Date and Time in Menu Bar” and the box I checked was not checked off even thought the lock was still locked.
I then moved my cursor up to the menu bar in the upper right corner to see what would happen and the spinning beach ball started up but only for the original icons such as Bluetooth, Mobile Me (which I do not use), Time Machine, Spaces (doesn’t indicated the number when I switch Spaces, etc. The icons Norton Anti Virus and Tech Tool Pro in the menu bar are okay.
Also, when I attempt to shut down my computer the system clears the icons from my desktop except for a picture I have on my desktop and I get a gray wheel spinning and the system just hangs until I press and hold the on/off switch. I don’t know if the clock and shutdown problems are related.
The only new software I loaded recently was Skype with Logitech WebCam for the Mac and Quicken 2007 (Had a problem with Quicken 2006). They both are working okay.
And ideas on why I cannot get my clock to show up and my computer to shutdown?

You may have to consider a new post in the Hardware forum area for the computer
model and build/year; if there is a possibility of some basis the matter could be in
the machine and not the software running within it.
Your last two/three posts are in the Leopard 10.5(.8) forum area and do indicate
some kind of problem where troubleshooting the computer to discover if the matter
at hand would be either hardware or software based, may be the way to go.
The link to the 10.6 Snow Leopard forum won't be of help if your computer is a
PPC-based G5 tower, or other older pre-Intel configuration. And I remember
your earlier questions about the iMac G4 and some other issues in the past.
You may ask the moderators to put your post in a new thread of its own, in the
Leopard 10.5 area; so as to not 'piggy-back' another topic; even though some
of the odd issues you've had seem similar to this OP's topic line and appear to
be in the same general series of hardware. {The question here seems valid.}
The routine suggestions to check, test, verify, and perhaps repair or replace
the system; save a bootable clone to suitable external standalone device if
testing a suspect computer's viability is recommended; and the basics if not
already tried to help isolate the issue(s) as you've posted elsewhere, may be
of some help to try and do; so in that matter, a new thread of your own is best
for your own directed feedback. Since this kind of advice applies to most any
situation, including troubleshooting what may be hardware or software, I'm
adding my two and three-tenths cents worth here.
Your original included Apple Hardware Test may be of some help, in the process
of elimination; but is not conclusive, so other methods would be also suggested.
Some ideas appear to cover the same ground. However, system corruption or
disc failure can also manifest itself in odd ways & affect things indirectly for a time.

and re-applying the last OS X update Combo file over the same one
already in the system; or if not up-to-date already, check & repair all
the general items and then apply the last Combo update.
A too-full hard disk drive can compromise the system integrity, so that
is a matter of course to keep up on what resources exist and remain
for the OS X to function correctly and for apps to multi-task together.
However that works out...
Good luck & happy computing!

K8N neo4 plat northbridge fan

The fan on my northbridge(K8N neo4 plat ultra) has died on me. Is there a replacement that is orderable? or am I looking at replacing the mobo?

I had one of these laying around & mounted it to my Neo4 as soon as I took it out of the box - Because I heard plenty of bad things about the stock fan.

Very quiet, cools great (never exceeds 32C) & fits perfectly.
You can see a pic of it mounted here - https://forum-en.msi.com/index.php?topic=93129.360
Just scroll down that page until you see some system pics
