MSI K8N Neo Platinum Nforce3 250GB - PSU?

My sister in law have this board, MSI K8N Neo Platinum nforce3 250gb chipset, recently the power supply sounds noisy and a high frequency sound from the Antec Truepower 380W SP. Had maked an RMA to Antec and they had agreed to replace the 380W psu with SmartPower2.0 450W. But they asked me one question, that im not sure about:
"Make sure that your motherboard does not need the -5V. If you want more information on the power supply you can look at this link: http://www.antec.com/us/productDetails.php?ProdID=26450 "
So, do Antecs SmartPower 2.0 450W suits this board and what really is -5V for? As I read the manual, it said ATX 20 pin power connector: JWR1 and at pin 18: -5V
So does it mean this board need a psu that gives -5V on ATX 20 pin power connector and thos board can't use with Antecs SP 2.0 450W?

Hi!
The K8N Neo Platinum (MS-7030) doesn't use -5v to anything.
So the -5v from the old atx spesification is not needed in your case.
WoW, thanks for fast reply!
So, it won't be any problem to use Antecs SmartPower 2.0 450W with this board then? Want to make sure about it, before accept Antecs offer for replacement and had spent over 4 days to find the problem with his computer. Really don't want to do it again.
This is his riggs:
Antec Sonata
AMD 64 3000+ S754
Corsair Value S. PC3200 DDR 512MB
Maxtor Diamondmax 9 250GB SATA
Maxtor Diamondmax 9 IDE 160GB
Sapphire Radeon 9550 Atlantis 128MB DDR
and
Accton ethernet card on PCI slot
MSI D-Bracket2
so
With the "new" Antec SmartPower 2.0 450W
Any problem with this rigg and PSU?
edit:
Dound this post that it said the board do need -5V and now Im confused?

SATA port multiplier on MSI K8N Neo Platinum - NForce3 250Gb?

Hi,
I have a MSI K8N Neo Platinum, which uses a NForce3 250Gb chipset. I have read that port multipliers can use either SATA or SATA II hosts and drives, but I don't know if the technology is 100%, transparently compatible.
Is the aforementioned chipset/motherboard compatible with port multiplier technology?
Does it support FIS, which gives the greatest perfomance?
Does it need a BIOS or driver update?
Thanks for the attention
Brazilian Joe

MSI K8N-NEO-PLATINUM nForce3 250 + Corsair vs.

Hi, I'm thinking of buying a new computer with a MSI motherboard and now thinking if these will correct and have no direct problems, MSI K8N-NEO-PLATINUM nForce3 250GB + Corsair VS512MB400 Value Select 512Mb DDR PC3200 400MHz 184pin Unbuffered CL2.5. I'm not the guy who is intresserd in overclocking and such things.
Will that motherboard and memory correct good with each other ?
Sorry for my bad english. :D
//Johan
EDIT: I think I made this topic in the wrong forum. Mods move it to AMD64 nVidia Based board ?

MakubeX,
I have the Antec True Power 480. Unfortunately it only has 22 or 23 amps (the specs and the label on the psu have different ratings ) on the +12V rail. Most of the folks here recommend a power supply with at least 24 amps.
The good news is that the system in my sig is working flawlessly so the extra 1 or 2 amps don't seem to make a big difference, at least in my case. I will say, however, that according to Core Center my +12V rail runs around 11.5 volts, which is low and nearly out of ATX sepc. The low voltage will result in higher amperage draw...but again, the system is stable.
I wish you good luck

K8N Neo Platinum (NForce3 250GB) and SATA2?

Hi!
I have MSI K8N Neo Platinum with chipset NForce3 250GB. It has SATA Controller. Can someone tell me (with certainty), if I can install a SATA 2 drive? (Once I contacted Maxtor, they told me that I would rather not install a SATA2 drive in a NForce3 250GB based mobo) Has anyone had a problem with a SATA2 drive in this mobo?
my pc is:
AMD 64 3000+
MSI K8N Neo Platinum
2*512MB Kingston DDR400
200GB SATA SEAGATE
320GB SATA WD
Thanks in advance!

Figures , as Maxtor is the vendor that has problems with their sataII DiamondMax drives on nforce3/4 buildt in sata controllers.
However , Hitachi T7K250 250GB SATA2 is one that works flawlessly on nforce3 .
They are also set to sataI from manufacturer .

but for some reason its giving the blue scree with dumping memory msg on the screen.changes the memory but still got the same problem updated the bios to 1.5 still same thing.
any cue with the problem.
thnks

System restore? You need to find out what's causing the problem and you have too many things connected to it to be able to figure out what it is, always start with a basic system - video, primary hard disk, cd + fdd, no more and nothing else connected. Then when something goes wrong along the way you'll have more chance of narrowing it down if the problem appears.
What you'll want to do now is disable/uninstall/unplug any additional non-system-critical components that you have connected to it such as extra usb slots, printers, scanners and anything else. Keyboard, mouse, video with no sound and see if the problem persists. If it does, try another video driver. If it's fixed then reconnect/enable one device and try again until the problem reappears and you can find out what's causing it -- unless you can speed read that message quickly before it shuts down
Now that I think of it, have you set the OS to not automatically reboot on any errors? That might keep the BSOD up there so you can note it down and hopefully point at the problem instead of going through all the above hassle ^^

When i try to install windows, during the process it reboots, and i can't do nothing.
I already try with another motherboard, and another energy supplier and the system works just fine.
The motherboard is brand new, and i never used it before.
Is this problem from the motherboard?
Please hepl me.

When did you bought it? How long does the mobo didn been used? Have you tried to reset the Bios again by removing the CMOS battery and leave it for 10-30 min? Make sure you removed the power connector before removing it. Gd luck.
P/S: Please gives more details on your current rig including the PSU and Bios revision like in my sig so others can help you!!

changed hdd, change gfx-card. change psu, removed all no-need pci-cards..
but still same error, i aint no expert so i might have missed something in bios or something :(
please help me if you can..

Flashing bios with memory errors is a veeeeery bad idea .
Almost guarantied to ruin your bios chip with bad data block.
That this even is suggested with mem errors , well .
You need to resolve the mem errors before doing anything else.
The windows xp install routine is a very heavy user of cpu and memory
and will fail if you have mem errors like you have.
Some things to try is entering bios and change auto settings on cpu voltage
giving it 0.5v more than default .
Set the memorys voltage to vendors max approved voltage
which for yours is 2.6v +/- 0.1v . So it's safe to set at 2.7v .
Set timings to cas 3 ,ras 3 ,trp 3 , tras 8 , CMD 2T.
Pushing it firmly down in the dimm socket , sometimes it's not all the way down there even if the plastic lockers snap in.
Disconnect all devices not needed for a windows install ,things can be added later.
Have only the hd that os is to be installed to , one cdrom , floppy , memory and
gfx card .
Disconnect USB case front connector (cause corruption and strange faults if
USBOC pin is connected)

Any MSI K8N NEO Platinum Edition S754 nForce3 users?? Need advice..

Hi, thinking of building a budget system around a S739 Clawhammer 3700 with an
MSI K8N NEO Platinum Edition S754 nForce3 board. But have a few concerns..
- Will this board run on this chip or will it need updated BIOS to do so?
- Will it work with crucial 3200DDR memory.CL=3 • UNBUFFERED • NON-ECC • DDR400 • 2.6V • 64Meg x 64 ?
- Can it take an extra (3rd) 512 stick of this ram?
Thanks.

I have ran the Neo s754 model with 2 * crucial CT6464Z40B 512MB cas 3 modules and never had one single problem with the combination
of A64 GC version , mobo and RAM .
Three modules is tough on the single channel memory controller though , as it would have to deal with 6 banks
and you probably see the ram max speed as DDR333 and 2T commandrate is what it can cope with.

- Support K8 Sempron CPU.
- Turn off keyboard LED in S3.
--Quick Guide for flashing BIOS, provided by MSI--
1. Create a MS-DOS boot diskette, then copy the the .exe and the bios file to the floppy disk. Both of these files can be found in the package you downloaded.
2. Press "Delete" and go to BIOS setup while computer bootup.
Check BIOS advanced features and see if BIOS flash write control is enabled
(This option must be enabled. If you can not find this setting, it means the BIOS can be
flashed.)
3. Boot from MS-DOS boot diskette and get a:\> prompt.
4. Type "", then press ENTER
5. The flash program will then ask "Do you want to save BIOS?", please press "N" for no. The when you see Press 'Y' to program or 'N' to Exit, please press "Y" to continue.
6. After flashing complete, remove floppy and reset the system .
7. Press DELETE or F1 when prompted at first reboot after flashing.
8. Load BIOS optimized defaults, then save settings and exits.
Drivers & Needed Files:
(Note: All these drivers are for Windows XP.)
Leaked Nvidia nForce3 Chipset Drivers Version 4.40
(Please use at your own risk, these are LEAKED drivers. Password for the .zip file is "ocworkbench rules". Also, you will need to rename the WinXP_2K folder in IDE to either WinXP or Win2K else the installer doesn't pick it up.) Thanks for the link Wonkanoby!
*NEW* Leaked Nvidia nForce3 Chipset Drivers Version 5.03
More leaked drivers? Seems some parts of the drivers are older and some are newer.
1. Windows XP Service Pack 1A (Web Install) -or- Windows XP Service Pack 1A (Full Install)
2. Microsoft DirectX 9.0b (Web Install) -or- Microsoft DirectX 9.0b (Full Install)
3. Nvidia nForce3 Chipset Drivers Version 4.24
4. AMD Athlon 64 Processor Driver Version 1.1.0.14
5. Nvidia Video Card Driver Version 56.72 -or- Omega Nvidia Video Card Driver Version v1.5303
(The Omega drivers are third party drivers optimized for gaming, most prefer these over the standard Nvidia drivers.)
5. ATI Video Card Driver Version 4.7 -or- Omega ATI Video Card Driver Version 2.5.51
(The Omega drivers are third party drivers optimized for gaming, most prefer these over the standard ATI drivers.)
6. Onboard Sound Driver (Realtek AC'97 Audio Codec) Version A3.61
It is HIGHLY reccomended that you install the drivers/needed files in the order listed above. Please note that there are two #5's because you either install one or the other depending on your video card, do not install both of them.
You will come across a problem here though. You can't install the chipset drivers without installing the Windows service pack and DirectX first, but the Windows service pack and DirectX installs need the internet to download files and you won't have working internet until you install the chipset drivers. Here's what I did to get around this. Instead of downloading the web install versions of Windows service pack and DirectX, download the full version and and put them along with all the other drivers on a backup hard drive or burn them to a CD, this way you will have all the drivers you need when it's time to install them and none of them will require the internet to download files.
Another note when installing drivers. Apparently the Nvidia chipset drivers also come with drivers for the onboard sound, but people seem to agree that the Realtek onboard sound drivers are better. When you are installing the Nvidia chipset drivers, just be sure to uncheck the box for sound drivers when it asks you which drivers you would like to install. Now you can safely install the Realtek drivers without any chance of conflicting sound drivers. Thanks for the tip Wonkanoby!

The installer still reccomends to install it beforehand for full USB 2.0 functionality... I would have put what you said in there but I wanted to keep it as simple as possible.
oh. IIRC the installer just says USB 2.0 will be fully functional after SP1 is installed. So after you install SP1 you go into device manager and u click update driver and it will auto search and update the driver.
Simplicity-wise, i guess its pretty much equal. It might take less preparation to just copy DX9 full onto a CD and install that first, then nforce driver, then right away you have yoru internet connection.
but i dunno.. i guess i will try it your way this time when my RMA"d board comes.
i will be fomratting and doing a fresh install later on today and will let you know if i come across any problems

Nothing has ever been overclocked on this system.
Everything is plugged into a Belkin Surgemaster powerbar.
I haven't mentioned the power supply. I'll get to that. I have been using an ANTEC NEOPOWER 480W POWER SUPPLY (ATX12V DUAL 12V RAILS ACTIVE PFC W/ DETACHABLE OUTPUT CABLES) for about a year on this system without
any issues. One morning, I wake up, hit the power button on my coolermaster case, and nothing happens.
CPU fan won't even spin. Nothing happens.
O.k., blown power supply, I think . . . .
So I take out my Antec and put it in another system. That system turns on
without any problems.
Hmm . . .
I come here, and I read posts about
potential compatibility issues with Antec power supplies. But if it's a compatibility
issue why was my system working for about a year?
O.k., fine. I'll buy a Enermax 535W EG565P-VE FMA 24P (115/230 VAC) power supply.
I just plug it into the mainboard (nothing else). Hit the power button . . .
The CPU fan spins for half a second, and then nothing.
Did my motherboard just suddenly die for no reason?
Any suggestions?

Pull the AC plug from PSU and set cmos in clear position with battery removed for atlest 20 minutes perhaps longer .
Then try to post the system barebone .
Just cpu,1 pcs memory in slot 1 , gfx card , and keyboard in PS2.
No usb devices at all including card reader and no pci cards harddisks or cdoms/dvd/floppy.
It could also be caused by a short or a malfunctioning fan connected to mobo.
Try to disconnect all case fans from mobo headers if you have any connected to additional fan holders.
The chipset fan can also be disconnected momentarily just to see if it posts.
If none of this helps , replace cmos battery and try again .

let me know what you think.
The other related posts I read, people were using raid or multiple OS. I'm not.

I had the same issues as you sometimes Windows would install and sometimes it wouldn't the problem was related to ram. I had my ram in slots one and two like you did and I moved the ram to slots 1 and 3 and now the machine is rock solid stable.
I think most of the problems people are having are actually more ram related than anything else.
So try moving the stick of ram you have in slot 2 to slot 3 and see if this solves your problem. This solution is on forums somewhere I am just not sure where.
Take care,

Help with MSI K8N Neo Platinum

HELP please- motherboard MSI K8N Neo PLATINUM: I tried to take away the backplate for the heatsink (on the back side of MB) in order to install the zalman HS beafore i read the forum (use a fan...) and the worst of all happend:
I scratched the back surface!! the scratches are minor, that is 4 scratches half a milimeter long each and not deep but i can see the copper of some lines leading from the memory slots to the processr. My question is : can I try and build the computer on that motherboard anyway or better buy a new one? is there a risk of dammaging other components? oh god what a mistake!

Make sure the new backplate is non-conductive. The backplate for the Hyper 6 has a non-conductive sticker on it. Make sure to keep it on if youve got one... If the lines are exposed even with the back-plate on perhaps you should cover them with some non-conductive (100% non conductive!) tape or something.
Then it doesnt matter if they are exposed, as long as they are ok.
A good tip, which got when i was removing my backplate, is to use a blow dryer to heat it up and the remove it with your fingers. That way youll also notice if it gets to hot
The glue gets sticky at blow drier temps. And pls, dont singe the MB with your blow dryer, you only have to make it hot, and if you cant touch it, how can you remove it with your fingers?
I guess theres no way of telling if you have a serious prob and no way to tell if your cpu will be ok. I guess you could (?) try and start it wíthout anything (cpu, mems) but a PSU, and then, if it (and maybe the PSU) goes "!Pfsssssss!" or "bang!", youll now you will have to replace it.
I put a screwdriver through an asus board once, and it still worked...

MSI K8N Neo Platinum & Crucial Ballistix 512MB RAM Problem

I have had MSI K8N Neo Platinum and 1x Crucial Ballistix 512MB RAM for 11 months.
I have had 1x Crucial Ballistix 512MB RAM for 2.5 months, for a total of two.
I have had MSI GeForce 6600GT (NX6600GT-VTD) 128MB AGP for 1 month.
For about 1.5 to 2 weeks, I have been seeing random crashes while playing PC games.
I started a thread on the Hard OCP forums a few days ago. I did not know MSI had forums =)
Rather than re-typing, I may as well just post the link:
http://www.hardforum.com/showthread.php?t=934956
My issue is also similar to this one:
https://forum-en.msi.com/index.php?topic=83799.0
Thanks for the help.

ALL RIGHT, after almost FOUR months my issue is FINALLY resolved.
It is amazing how much time passes when you are hesitant to buy parts unless you are 95% sure it will fix the problem.
OK, here is an update as to what I remember.
I went to BIOS 1.4 and tried many different physical and BIOS RAM configurations (Different seating, different number of DIMMs, different RAM timings, voltages, etc).
I concluded that I could not make my PC 100% stable, but I could get it darn close. With certain settings, such as DDR400, 2-2-2-6, 1T, 2.80V, Aggressive Timing enabled, Memtest failed test #5 every time (this is spec for my RAM). With other settings, such as DDR333, 2.5-3-3-7, 2T, Auto V, Aggressive Timing enabled, Memtest failed test #5 maybe once out of 5000.
I also concluded that the RAM voltage and Aggressive Timing setting was having a big impact. Some settings would not work (failed Memtest) with RAM at 2.80V but would work with RAM at Auto V. Some settings would not work (failed Memtest) with Aggressive Timing enabled but would work with it disabled.
Finally, I started to occasionally get R,G,R,G (Processor Initialization) on the D-Bracket upon cold-start & warm-start, which suggests a PSU issue:
https://forum-en.msi.com/index.php?topic=76972.msg542545#msg542545
That pushed me over the top, and I decided to buy a new PSU (TG-480-U22) and a new SATA HDD (WD2500KS) just because.
Problem solved. Thanks for all the help.
I will continue to buy MSI in the future just because of these forums…and a good product of course!

MSI K8N Neo Platinum with Vapochill Case problems - Help anyone. :)

Hi all,
Had a bit of a tricky problem and as Im new to this board I have no idea what could be causing this.
First all all system specs:
Athlon 64 3700+ Clawhammer
MSI K8N Neo Platinum -
1 gig Corsair XMS ProL Low Latency Ram (2 x 512mb)
Nvidia Gefore 6600GT
1 x WD Raptor 10000rpm HD
NEC 2500a DVD writer.
Eye-T 550w PSU.
Vapochill SE Case with installed Vapochill Phase change cooling.
Here are photos of it in its present state, you will notice that it isnt installed in the case at the moment.
The reason for that is because the two wont work together and I want them to so so bad...
So, hopefully someone here can save the day for me - here goes.
I have tested the Motherboard and all other componants outside of the case and everything runs smoothly and there are no problems what so ever, great.
I have also retested the Vapochill case with another motherboard and that also works without a hitch.
The problem comes when I insall the MSI board into the system, all hooked with a really basic setup, PSU, Case cooling, CPU and Ram. Flick the on switch on the power suply and the system turns on for around 1/2 a second then turns off again. I found this strange because it soundnt come on at all until I press the power button.
If I press the power button the same thing will happen over and over.
I have tried a different powersupply and this does nothing at all.
I have checked for shorts and there is no possible way it is shorting on anything.
I have a fan plugged in where the CPU fan would go and this doesnt help.
I have taken it back out and tested it again and it still works ok.
Does this sound familiar to anyone? Are there any secret Bio's menu's that would have an option that would solve this?
Any help would be greatly appreciated.
Glenn

When you are running the MoBo standalone, what are you connecting to the Power, Reset, HDD, etc. pins ? Are you using the wires from the Vapochill case, or something else ? It looks like a single cable with an intermittent switch (red/white cable). I once had a similar sort of problem and it was because I hadn't connected up (the incredibly fiddly) cables correctly. Other than that, I would have gone for a short of some sort - but you have checked that already, so . . . .
As to the system starting to power-up when you switch on the PSU, I wouldn't worry too much about this. It seems to happen from time to time with some of my systems - amongst other things, the BIOS can be set to resume to previous state after a power-fail.

MSI k8n neo platinum post problem

I just bought a 2nd hand K8N neo platinum and I can't get it to post, I have reduced down to 1 stick of ram(tried all slots) vga and cpu running out of case. I have an ultra 600 psu that certainly should be doing the buisness as everything was fine on an NF7S-V2 up until 1/2 hour prior.
On the led device it's starting 4 red then after a couple of seconds it goes 1 red 2 red 3 green 4 red which I found relates to keyboard controller. I've tried with various keyboards but no joy. I get nothing on the screen at all but that's the next stage in post.
My memory is Twinmos 3200 twin x 2 x 512 double sided, which I saw in the sticky can be troublesome.
Any body got any ideas?

i am having an almost identical problem.
First the system wont go past post,then i realised it would but only boot if i had the USB mouse unplugged (i noticed the d-brackets lights changed after i unplugged the mouse)
then i was able to get to windows, however i couldn't do much (mouse wouldnt detect if replugged, keyboard not detected - all lights off)
So i tried clearing the CMOS
now i am having the same problem, except this time i get CMOS checksum error - defaults loaded
then it tells me to press f1 to continue to del to enter setup, which i cant do since the keyboard wont work. so now im totally bamboozled
I've tried changing the PSU as well with no luck (both were 500watts)
Funny thing is, the pc having the problem is identical to the pc im writing on now, presonally i think the motherboard is not v good, since alot of people have this problem or similar to it. (and yes im using the keyboard and mouse now, that i tested on the other pc)
SPECS:
MSI k8N Neo Platinum
Powercolor Radeon 9800 Pro
AMD 64 3000+
1GB Geil Memory
Maxtor 160GB
500watt Magna Dual Fans
Will check what the D-bracket says and will report back.
ok here goes:
(with usb mouse plugged in)
1= green
2= red
3=red
4=green
(without usb mouse plugged in) - but bare in mind i cant press f1 (no keyboard) to continue else i would probably be able to get to windows.
1= green
2= green
3=green
4=red
