K9N2 SLI Plat MS7374 Plat - Setup Raid 1 on SATA 5 & 6 Ports

Hello again,
It has been quite some since I was on the board, but you really helped me out last time.
I have 2 Seagate 500GB 2.5" drives I would like to setup a Raid 1 configuration on SATA 5 & 6. Currently one is my boot drive (SATA 1) and the other drive (SATA 2) has not been partitioned or formated. I say this because, Diskpart can see both drives but Disk Manager cannot see the new drive on SATA 2. I am guessing I will have to partition it and make it a primary & active partition then NTFS format the second drive.
I am not understanding the manual that came with my board. I have never set up a raid configuration before. Can I get a blow by blow or pointed to a good manual on how to get this done? At what point do I move the drives to the SATA 5 & 6 ports?
Thanks so much!
Regards,
ManDown

K9N2 SLI Plat AM Bios

I think I'm having a problem with the BIOS settings. When I plug two DVD burners into SATA ports 5 & 6 they are not seen by the OS. Is there a BIOS setting I need to change to fix this?

K9N2 SLI Plat. showing 2 HD Audio's in device manager

quick basic system setup.

EVGA 9800GT
320gb WD SATA 3.0

Installed Windows MCE 2005 w/SP3 and everything up to date driver wise. Problem is HD Audio device is showing up twice in device manager. One shows installed, one shows that no drivers are loaded. I have uninstalled the device and uninstalled the drivers, and reloaded everything. Used drivers from CD and from download, but not luck. Any ideas on what could cause 2 of the same audio devices to show up and only one to actually load, besides a general hardware failure on the motherboard?

That would make sense, if either the 9800GT or the K9N2 had and HDMI port. Sorry guys that's a no go. This is the first time I have ever run into this issue. 2 of the same audio devices showing up in device manager. One has drivers and loads, other shows unknown HD audio device and will not install drivers at all....

K9N2 SLI Plat and 630 Propus

My wife just bought the 630 for me (early Christmas) and I was wondering if anyone has tried it in the K9N2 SLI Plat. I see the 600e and the 605e, but not the 620 or 630. Do I now need to get another mobo? Any thoughts? Thanks for the help.

Re seat the CPU and make sure its properly installed, also remove power cord from the PSU and do >>Clear CMOS Guide<< then retry

K9N2 SLI PLAT 1 vid card for PhysX only make both cards run at 8x?

Hi all. I'm on the fence here as to what to buy. My current setup is (hopefully) displayed
in my signature.
Here is my concern as copied from the K9N2 Sli Platinum Manual:
"• 1 mazarine PCI Express x16 slot with x16 operation (PCI Express Bus SPEC V2.0 compliant)
• 1 light-blue PCI Express x16 slot with x8 operation (PCI Express Bus SPEC V2.0 compliant)
• When 2 PCI Express x16 slots are all installed, the PCIE x 16 lanes will auto arrange form x16/ x0 to x8/ x8. Do not use the light-blue slot when only one PCI Express x16 card is installed."
Is this normal for most SLI mainboards? I was thinking of upgrading in one of two ways:
1) Just purchase a 9600GT for PhysX only and pop it in the other PCIE 16x slot
OR
2) Go all out and buy another GTX 260 Core216 SC card, new Power Supply, and new PCIE Sound Card
and SLI the 2 cards together.
With option 1, will my GTX 260 get slowed to 8x ?? That may defeat my whole purpose for getting
another vid card and dedicate it for PhysX; would it slow the main card down enough to impact it greatly?
With Option 2, the reason for a new sound card is a second "2 slot" vid card means I'll only be able to use
one of the 2 PCI slots. Currently, I have a Fax Modem and a SB Audigy SE in them.
I use the modem on a regular basis to send/receive faxes, so I will have to replace the sound card.
Anybody know if a Creative Labs SB X-FI Titanium PCIe can fit in the 1x slot between 2 SLI'd Vid cards?
The 1x PCIE slot on this board is between the 2 16x slots, not the ideal spot I fear.
If it won't fit between, my ONLY other choice would be to use the on board sound, which I am
not fond of doing.
My whole intention here is to play Cryostasis better than it does now, AND hopefully be ready
for any newer games that incorporate PhysX. As it is now, I got Cryostasis free when I bought
my new vid card, nice of eVGA to do that
If I do this, I want it to be pretty future proof:
I don't want to make EITHER investment solely for one game only. I'd prefer to
go with option 2, but I REALLY don't want to find out AFTER I buy everything that
I can't fit the new sound card between the 2 SLI'd cards :(
Any help on this will be GREATLY appreciated,
thank you.

K9N2 SLI Plat Overheating

First, I consider myself a novice when it comes to inner workings (BIOS, voltages and such), so I probably should not have tried to build a box from a barebones kit. Now that I am in that situation - problems are arising!
my specs:
K9n2 SLI Platinum nForce 750a
BIOS v 3.4
AMD Phenom X4 9500 4M 95W Socket AM2 CPU (CP1-AM2-9500 )
Ultra LSP550 550w Power Supply
HITACHI 1TB SERIAL ATA HD 7200/16MB/SATA-3G
Ultra XBlaster Mid-Tower Case Black
OCZ Blade PC6400 800MHz 8GB DDR2
Vista Home 64-bit
No floppy drive
EVGA GeForce 9400 GT 1GB PCIe - not installed yet
Everything was going great for about a week, but earlier today I installed the newer NVIDIA drivers v15.25 (I believe). Everything worked normal for several hours, but then I noticed that the CPU temps were skyrocketing from 37C to nearly 80C in just a few short minutes. I opened the case and ensured that the heatsink and fan were working properly, and all looked good. I went into the BIOS settings and looked through the hardware monitor and noticed that the temps were still rapidly rising and that the voltage was unstable bouncing around 1.6 to 1.7. I think that is the problem and the CPU fan is running about 1600 RPM, which may be normal, not sure. I looked at the Cell Menu and it said the CPU voltage was on auto.
So far I tried to Load Optimal Settings and Load Fail Safe Settings, both to no avail - temps are still skyrocketing within a matter of minutes. Only other change I made this week was buying a new heatsink and fan ('up'grade from the one that came with the CPU - to a Thermaltake TR2-R1. Again, the heatsink has been installed for several days, and have had no problems with overheating until tonight. Oh, yeah, and I do have 2 120mm fans, one front and one rear and the MB temp has been pretty steady at about 24 to 28 C.
Is there any hope?

Yeah, I definitely took the plastic off, and the heatsink material was already applied. I suppose I put it on wrong, but there seems to really only be one way to put it on - over the clips and tighten...
Interstingly, after letting it sit overnight and rebooting this morning - it is holding steady again at around 38C (in fact, I'm using it now). The voltage at boot up read 1.55 instead of auto today, so I quickly adjusted it down to 1.3 to see if I could keep it from going out of control again -so far, so good. It is just a mystery as to why it (bios) is changing so frequently without me making any adjustments to it. I've read here and other places that there are possibly issues with this board and earlier bios versions. It came with v3.4, and I have never tried to flash to anything else. Should I try and re-install the heatsink? or does it sound more like a bios problem?

K9N2 Sli Plat - HDD detection problem

[Split off from https://forum-en.msi.com/index.php?topic=127332.0, please don't hijack other topics! - Stu]
You are not alone..... I'm having simular issues
I flashed my bios hoping to fix the HD detection for installing windows.
now I get nothing detected in the bios. as SATA drives. IDE channels detect.
Ihave flashed the bios both ways USB and CD bootable image.
I get a NVIDIA HDCP: ROM HOLE 2 PROTECTED!
During the flash. Is that supposed to happen? everything else looks good during the flash. However now I can't even get drivers to see the SATA drives. I've tried 2 different makers.
BIOS is set to IDE on the SATA.
Note Same MB as original thread starter. 8GB OCZ memory, hitachi 1TB HD, 160 GB Maxtor HD.

K9N2 SLI Plat CPU support

I have been trying to access the cpu support list and it keeps timing out. Curious if anyone else is having problems. Is this info available any where else? Thanks.

From googling; the comments to the right may be useful reading:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813130161
OK someone got it to work, but had to adjust the VCORE before using it, I consider something official when I don't have to do that, there are a lot of users out there that don't overclock, I'm one of them, I know how and I've overclocked this 7750 to 3.4GHz stable with stock cooling, but I'm happy with 2.7GHz stock for now. I'll be upgrading to the the 980a - G65 soon anyway, not going to blow money on a 955 now, will wait til both the board and CPU come down in price.

P6N SLI Plat + Adaptec 1220 pci-e sata card = lockup and no drive detection

Well today my adaptec aar-1220sa pci-e sata adaptor card came in and I was eager to install it. My first attempt to boot up without a drive attached was met with a slow bios screen and then when windows vista finally got to the desktop none of my usb peripherals would work. I flashed the card to the latest bios and installed the newest adaptec drivers and if I hook my wd sata drive to it I cannot boot. If I leave it in with no drives attached it will let windows boot however the usb hub is out and I have to remove it in device manager and then reinstall it in order to get my mouse and other usb devices back up and running. I was wondering if anyone else had tried this card and if you got it to work what did you do? So far for me it will not detect any sata drive that I hook up to it. Thanks.
PS: I'm going to rma this thing as I've never had a drive controller behave like this thing does. I don't think that it was ready for prime time yet.

Quote from: Puffnstuff on 03-May-07, 00:59:46
My problems were all induced by the adaptec card. Once it was removed from the system everything went back to normal. I've used many add in drive controller cards in my day and none of them have behaved so abnormally as this one did. I believe that the problem is entirely with the adaptec sata adaptor and not with my system or mb. If I have to add more hd's I'll get a pci card or just add ide drives since I do have a free slot available.
I have used 2 eSATA cards on previous systems. Always ran like garbage and screwed up the boot process. Thats why i got the p6n plat with the esata onboard so I'd have no problems. My guess is you were having an IRQ conflict.

K9N2 SLI Platinum and Phenom II 940

I have a K9N2 SLI Platinum and have a Phenom 940 on the way. Are there still issues with bios 3.4? what is the proper way to flash to 3.4 so the volatge is normal ? I just flashed via the usb meathod but dont i have to reset and clear cmos? also what is the stock proper voltage for the phenom 940? is it 1.375 or 1.350?

have you tried uping the voltage, the black dragon works perfect at 1066 from 2.2v to 2.4v, however the gskill requires 2.3v to work perfect at 1066 (so my setup its 2x1gb geil and 2x1gb gskill (total 4gb) voltage set to 2.3v) if i dont set 2.3v i get completely random restarts (could be after afew hours or afew days), all passed with prime and occt.
just in case, after bios reset ddr is set to 800 as default ,go into bios and set divider to 1066, then set timings to 5-5-5-15 (dont use auto/sli ready) bios sets strange timings by default at 1066 then set voltage and save.
I've tried everything and even chatted with MSI Techs over it all, been back and forth between MSI and OCZ for about a month now.. bottom line, MSI told me was that they don't certify or support OCZ ddr1066 on the K9N2 SLI Plat; which OCZ Techs told me, basically. B.S! ...claiming they tested the Board themselves when it came out. However OCZ doesn't even have the Board listed on their RAM Configurator on their website; which they claim is MSI's fault... and so on, and so on...
Anyway, OCZ is offering to swap my Reaper Set for a different Model set which they claim is more reliable on AMD processors. Probably their Gold or SLI model set I'd guess; they don't even advertise on their website any difference in their sticks being "Intel Certified" or "AMD Certified" ... and so on.
Worse case scenario; if in the end whatever they give me still doesn't work, I'll EBAY it and try a set of those geIL Black Dragons.

MOVED: How to adjust CPU NB Multi, or HTT Multi in BIOS on K9N2 SLI Platinum?

This topic has been moved to Overclockers & Modding Corner.
https://forum-en.msi.com/index.php?topic=126239.0

Ok so that setting allows me to adjust the HT Link.... though it does this by multiples of 200... starting at 200; going up as high as 3000+
However I discovered that I can only go up to 1800. If I try to set it at 2000, then my system refuses to POST and I have to clear the CMOS and start over.
I also discovered that, changing this setting, does not seem to have any effect on the CPU-NB setting.
What does have an effect on the North Bridge; is changing the CPU FSB Frequency. However, not only does this adjust the North Bridge mhz, it also overclocks both the CPU and the DRAM frequency at the same time; but I can't get the North Bridge any higher then 2370mhz without again, causing the system to refuse to POST and resulting in me having to reset the CMOS and starting over.
The reason I was asking and trying to do this is; I was told by OCZ, if I can adjust my DRAM to around 1000mhz, and the NB to 2400mhz, then my ram, which refuses to run at 1066 without crashing my system; I was told my RAM would be preforming equivolent or better then 1333 ram. But it seems my K9N2 SLI Plat will not achieve that 2400 without becoming unstable.
The highest I can get it is 2370...

K9N2 SLI Platinum raid setup after bios flash

Hi
I'm building a new system based on K9N2 SLI Platinum. Apart from a new 80 GB sys. HDD everything else is reuse from another MB (MSI K9N Platinum).
Here is what is puzling me: Before trying to install WinXP i flashed the bios to 3.2 because of the included updates to the raid bios. Flashing went well, however in my setup I want the 80 GB HDD to be non-raid and the two 320 GB HDD to be raid1. I've set this up in bios so that only channel 5 and 6 is enabled for raid and would expect that the 80 GB HDD (channel 1) would show up as a normal sata HDD when starting up. But it doesn't - it is listed as 0.0 xxxx after the "press F10 to enter raid setup" message?
This is strange because I had the same HDD setup on my old MSI K9N Platinum and there the 80 GB sata HDD was shown as a "normal" disk and not as a "appendix" to the raid list.
Because of this I have problems installing WinXP on the 80 GB HDD
Any suggestions?

Hi BOSSKILLER
Thanks for your quick response.
Quote from: BOSSKILLER on 12-August-08, 00:14:44
Well, leave the 80GB only and install XP over it.
Then connect other two HDD's and enable RAID for them.
Unfortunately this didn't help. As soon as I installed the Windows nVidia RAID SW it prompted med that it had registered the 80 GB disk as a new disk that wasn't a member of any RAID. This happened everytime Windows XP was started.
The trick was to add the 80 GB disk as a Spanned disk using the nVidia RAID BIOS setup utility. Install Windows XP (again) and the Windows nVidia RAID SW and setup RAID 1 on the other two sata disk.
I don't think this is a great setup but it works. I hope that MSI will fix this issue in a later BIOS upgrade. It would be nice if the enabled/disabled for sata RAID setting actually worked.

K9N2 SLi Platinum - Raid Issues

Components:
Enermax Pro82+ 525W
MSI K9N2 SLi Platinum
AMD 5400+ Black Edition
2x2Gb SUPER*TALENT DDRII 800Mhz CL4
MSI 8800GT 512mb
1 X WD Blue 500Gb Sata2
2 x WD Blue 320GB Sata2 (NEW SET)
Basically, I've had only the 500Gb HD as the main disk, Now I've got a set of 320GB's for Raid, which i'd like to add to my current setup without Re-installing OS coz the main drive contains necessary Data etc. So I Enable the Raid settings in Bios as outlined in the Manual. Setup the raid in the Mediashield Raid Bios. Windows Vista 32 simply Bsods at the Windows loading screen, with latest MB RAID drivers from MSI & Nvidia tested, still the same.
I've discovered in other threads, people experiencing something similar. According to what I've learnt is the best is going to have to Set the single 500Gb Drive into a stripe and re-install. I've tried other alternatives, like leaving the the 320's as single drives and setting up the raid through windows Mediashield, same problem after rebooting. Compared to My older rig, RAID seems to not work so starightforward on the K9N2. MSI should be more Specific with instructions and limitations to implementing a Raid.
That's not my biggest problem here though, I've disconnected the 500Gb due to critical data, I've only got the 320's in Ports 1 & 2. Setup Stripe raid in Bios. I cannot succesfully install Windows Vista or XP to the raid, Vista install remains stuck @ the decompressing files window. XP loads until it's about to boot the OS for the first time then Bsods. Using latest Floppy Raid Drivers too. Has anyone with this board got a Raid with OS installed? Am i missing something here? what am I doing wrong?
I'm still Testing, gonna pull out my Aged and beloved Hitachi 80Gb Sata1 Drive from the dead, install OS and then get this baby to work in Raid as I want it to, Hopefully......
Will report back..

The RAID implementation on this board is really obnoxious, if you have installed windows (XP/VISTA) prior to enabling RAID in the motherboard bios, windows will keep restarting itself at the windows load screen. Not an OS problem but the way the RAID controllers work on this motherboard.
My raid setup:
1 X WD 500GB BLUE (System C:\)(Single Stripe)(HAS TO BE IN IT'S OWN ARRAY IN MEDIASHIELD ROM for windows to work if RAID IS ENABLED)
2 X WD 320GB BLUE (Raid 0)(Stripe)
1 X LG Optical Drive (Also shows up in Mediashield post screen when Raid controller is ensbled)
Make sure to back up all data before setting up an array, setting up a array on a single HDD and selecting NOT to delete the MBR should keep your data intact. Booting up the system with the previous installation not deleted but now with the system HDD in it's own array you will continue to get BSOD and auto reboots.
V3.3 Bios Settings:
1) Set 'RAID MODE' to 'RAID" within the Integrated Peripherals Menu.
2)Enable 'RAID' in the Sub-Menu "ON-CHIP ATA DEVICES" --> RIAD MODE set to RAID then enable the ports you want Raid enabled on. SATA 1.2.3.4 are NV raid 5.6 are JMICRON. I have have ports 1,2,3 & 4 enabled as all 4 of my drives are connected to those ports. Optical drives will automatically show up in Mediashield ROM post screen even if port is disabled, and once windows is reinstalled other HDD'S can be connected without having to enable raid or arrays and all will be seen as normal.
Now to install windows, had an issue with the Floppy raid drivers from MSI site so I used the MCP78 floppy from gigabyte
http://www.gigabyte.com.tw/Support/Motherboard/Driver_Model.aspx?ProductID=2819. Windows working and Raid 0 on 2X 320GB HDD. Once windows is installed to a single disk in this manner windows will work fine with sata raid disabled (deleting array in mediashield will delete MBR) and in IDE mode as but when raid is re-enabled it will detect the disk and work fine too. Another issue unresolved is that I couldn't successfully install to the Raid 0-2X WD 320gb blue stripe, anybody got windows installed successfully to a Raid 0-2X hdd stripe? Note, If installing to Jmicron you will need JM drivers.
Another issue I have since using Raid is that S3 mode is not working well at all. S3 is enabled in Bios power management and definitely worked previously when raid was disabled. Now I cannot get S3 suspend. When i choose sleep it goes into Hibernation, checked all vista settings in power management and it should go to sleep not hibernate. Any Help? When it comes out of sleep all the lights are red and I have to power it down, turn power supply off/on then post-> 'windows resuming' then only does it come out of hibernation, strange... Whether I choose sleep or hibernate this is what I'm getting. Using Vista 32, Nvidia driver version 15.24, display driver version 180.48. Jmicron drivers installed as well.

Welcome to the forum DaaDoctor
If you creat a signature (in profile) it will save you having to type your spec's out each time or us looking for it. Use mine as a template.
What PSU are you using ? Can you list the power output ? (writen on side of psu)
Going from your specs you listed your graphics card is very hungery on power so I would suggest your psu isn't up to the job under load.
Post the spec and we will know for sure.
