No, you do not have to install the SATA drivers to get XP up and running in non-RAID mode. I just did a regular install of XP SP2 and it found the SATA disk without any problem. Did four computers and did not have a problem with any of them.
Yeah, I realized after I posted this that the S-Bracket doesn't have the correct 3-pin connection for this motherboard. I have since edited my post so it doesn't confuse anyone.
Do you know why this motherboard is nowhere to be found? Every major online store has been out of stock for the past couple weeks.
renethx
It has been about 2 weeks, I think. Did you get a reply from MSI?
I have finally installed PC Alert, but it is a safety only when the PC is attended.
I've got this board with an AMD64 X2 4200 and I get high (95%, both cores) cpu usage after resuming from hiberhate. I checked the proceses and only the idle process is using any cpu. I've installed the Cool'n'Quiet, which seems to work as expected, except after a resume. Has anyone else seen this and is there a solution?
The FrontX RCA video jack works like a charm for coxial SPDIF in and out as long as you switch the location of the GND lead on the connector.
Looking at the wire, I'm sure the wire's characteristic impedance from the jack to the MOBO is not the preferred 75 ohms, nor is it coaxial, but it's only 24" of wire or so, so it shouldn't really effect the quality of the digital transmission.
For those who care, the SPDIF input works just swimmingly.
Thanks sjshwinn. I ordered mine 10 days ago and it has yet to arrive but I'm in Canada so I didn't expect quick delivery. Hopefully it will get here soon.
I got a reply from the Taiwanese Tech Support that the motherboard is designed to shut down automatically when CPU temperature exceeds a certain number. No further information was available from them.
As for PC Alert, the system will shut down automatically when CPU temperature exceeds the temperature you specified whether PC is attended or not. (Try to experiment by setting the "CPU temperature max threshold" low deliberately.)
In case anybody is interested, the latest BETA bios 3.33 (dated 3-14) also makes MemTest86 freak out.
Does anyone know exactly why that is? 3.00 and beta 3.13 have no issues at all with any of my ram.
I have 3 kinds of ram, 2x512 corsair DDR400, 2x1024 OCZ DDR500, and 2x256 some weird brand. All the sticks work for with bios 3.00 and 3.13 at "auto" and manual settings. I can and have run memtest / prime95 for days.
But NONE of my ram is happy in Memtest with auto or any manual setting I could find with 3.10, 3.20, and 3.33. Dunno about windows, too afraid to let it boot since it will probably corrupt everything. No overclocking either. Tried bumping the voltage too.
Don't the new boards ship with 3.10 or 3.20? Is there something I am missing?

Ah! Great! Thanks. It's more reassuring.
I have not seen this vital info on the MSI site or in the app itself. My CPU temp is so low now with CnQ (28° - 29° after 2 hours viewing/editing video clips and audio) that I have set the max threshold even lower: 60° seems out of reach.
First off, I?d like to say thanks to renethx, and all of the other contributors to this thread. The info here is going to make my new system go together much more smoothly.
I have the same question as piranhaj posted above about using a Theater 550 card with this MB,
I?m interested in using this card in a system I?m putting together, but I?d like feedback on whether I?ll have problems or not.

In addition to WebDirect, NCIX still has some of these MB's in stock.
I ordered mine from NCIX a few weeks ago (for a bit less than they?re asking now), and their service was excellent. I received the package a lot earlier than Canada Post?s ETA, but the online status was never updated until I received the package.

Hey renethx... I just noticed your sig says BIOS v3.2
Does that mean you don't get memtest errors? What's your secret?
Reading page 1 of this topic, I thought these bios versions had problems with RAM/memtest.
Since my post received no replies, and I see you running 3.2, does that mean the bios is fine, and my motherboard needs an RMA ? confused...
Using BIOS v3.10 or v3.20 does not necessarily imply Memtest errors. It depends on various factors. My two systems have never shown Memetest errors with either of BIOS versions. Of course MSI must have tested these BIOS extensively before releasing them. Unfortunately some people have reported Memtest errors with these BIOS versions. If your system is OK with BIOS v3.00 and v3.13, then your motherboard should be OK.
Are you running "optimized defaults" ie all "AUTO" settings?
With bios 3.13 and the OCZ DDR500, I can keep everything on AUTO and set CPU LDT to 250. With a venice 3200+ @2500/Ram @500, it ran memtest and Prime for over 2 days perfectly, all at the lowest voltages (FID on default too)
So I can't believe the ram and this board are incompatible... and I am NOT overclocking at all trying the other bios versions... this combo should do 200 x 10 like a walk in the park.
You didn't change any settings at all when you went to V 3.20? I'd really like to get this worked out while I'm still in the timezone for exchanging parts if it's not going to work right.

Regarding K8NGM2-FID availability, from the horse's mouth:
That was in response to my inquiry:
They were quick responding to my question -- just a few hours. Perhaps their Production Run management leaves them unable to respond quickly to a demand-surge. Anyway, sounds like the K8NGM2-FID will be available within a fortnight.
Still... what's the difference between FID and NBP and when will the latter arrive???
Edit:
Diff' between FID and NBP models:
From mindless staring at the product spec's, the difference between these models is "straightforward". The NBP drops IEEE-1394 (firewire) and adds TPM1.2 (some manner of secure crypto-service). Some places are now (in last 48 hours?) starting to list the NBP, but I haven't seen any FND boards back in stock.

Regarding the post link to the "S-Bracket" at http://www.censuspc.com (I've seen it several other places as well). MSI S-Bracket, 2SPDIF Jacks 2 Analog Connectors. I to was/am interested in this bracket. Not for coaxial SPDIF but rather for the Toslink transmitter.
The bracket description mentions 1x Optical S/PDIF, 1x Coxial S/PDIF jack, and 2x analog audio jacks for "additional 4-channel audio output" - this alone should indicate to you how old the bracket is - when was the last time you used 4.1 audio?
Anyway, I was @ work, and bored! - So dug I through the specs and manuals of a few older MSI motherboards that reference optical SPDIF. I believe this is the bracket from the KT3 Ultra2 Series motherboards.
According to the KT3 Ultra2 Series manual the bracket uses a 2x6 header connector (the manual shows a picture of a very similar/if not the very same bracket). The KT3 Ultra2 manual has pin definitions for the JSP3 header this S-bracket attaches to.
KT3 Ultra2 Series JSP3 header pin definition:
1 - VCC 5v
2 - VDD 3.3v
3 - S/PDIF output
4 - Key (no pin)
5 - Ground
6 - S/PDIF input
7 - Audio bass output
8 - Audio right surround
9 - Audio center output
10- Audio left surround
11- Ground
12- Ground
(Take this with a grain of salt as I haven?t actually seen the S-Bracket to
confirm that it uses the same header connector and pin layout)
My thought is that you could tear apart the toslink transmitter from this bracket
and rewire it for use on the K8NGM2 series motherboard... I can only assume that
the toslink transmitter uses pin 1 for the Vcc 5v (although there are 3.3v transmitters).
The big question for me is where to find a 5v or 3.3v source on the K8NGM2-FID
motherboard to connect my hacked toslink output to....actually the bigger question
is if its a good idea for a noob like myself to be messing around with adding a toslink
trasmitter to a motherboard that MSI clearly did not intend to have toslink on! :laugh:
any thoughts?

Toslink Output on K8NGM2-FID:
I would like an optical output to send digital sound to my HTDV's optical input (this would be a perfect match with my DVI-D to HDMI cable). This would be ideal as my HDTV has an optical output which will connect to my reciever. This is, of course, assuming that there isnt any HDCP to #*$&@ everything up!
So, I was @ work again - and decided to research adding an optical output to my K8NGM2-FID (which has yet to arrive btw!). Here are links found for any interested:

No. As my systems are overclocked, memory settings were changed accordingly (Memclock Value [166 MHz]). But Memtest errors never occur whether memory settings are changed or not as long as mem frequency is less than 220MHz.
I dont know much about this stuff, but I was researching this same topic... and
I found a link for S/PDIF Coax -> Optical conversion.{http://www.taligentx.com/projects/opticalconverter/}
According to this page... under the Circuit Description section.... "Signals for coax connections are transmitted with an amplitude of -0.5V to +0.5V, and the hex inverter brings this to the 0V to +5V level (TTL), which the Sharp unit can then convert to light."
So as my untrained and slightly ADD brain reads it... the electrical current in a coaxial SPDIF is different from an optical SPDIF. therefore a direct connection from a header intended for a coaxial output wont necessarily work for an optical output.
This S/PDIF Coax -> Optical conversion DIY page uses something called a "74HCU04 hex inverter" to guarentee that the optical SPDIF output gets the correct current, voltage, amplitude - whatever - from a coaxial SPDIF output.
After looking around a bit - I found the EVGA Bracket which may do this electrical conversion stuff for us.... http://www.evga.com/products/moreinfo.asp?pn=203-SP-0001-01&family=99 ....
and so I can learn abit - how did you supply it a +5V signal???
Well... the ASUS board comes with a 4 pin connector using 3 leads, the connector positions are: +5V, key (NC), SPDIF, and ground. Using a safety pin I popped the leads out of the 4 pin connector, and gave each lead its own one pin connector. I also put a 250 milliamp fuse in the +5V wire to ensure I didn't fry my moboard (although it turned out not to be necessary, the current draw is minimal). I ran the SPDIF In and ground to the moboard JSPDOI. I pulled the +5V from one of the JUSB2 VCC connectors. Using a multimeter I verified the +5V line was getting proper voltage and drawing a current, but the LED still wouldn't light up...
USB ports are designed to provide power, so the risk of frying the board using the +5V VCC line to power an LED is minimal... the fuse was there more for peace of mind... can't remember exactly what the current draw was (50 milliamps or something like that) but it was the same for both the ASUS board and the MSI.
The boards must be provided different SPDIF signals (either voltage or modulation...) to the bracket. The mystery to me is that the bracket correctly transmits the signal for coax for either board, but only optical for the ASUS. I appreciate you passing on the other threads... I'll dig through them as well to see if I can resolve the mystery.

No matter what supply voltage these modules are expecting, I'm fairly certain they are expecting a TTL level input not coax.
I managed to get the Asus bracket working for both coax and toslink.
The Asus bracket is expecting a TTL signal to run the toslink transmitter and it converts it down for the coax out.
I used the Coax -> TTL circuit on this page with a couple changes:
http://www.andrewkilpatrick.org/mind/spdif/
I omitted the 75 ohm resistor and added a .1uf capacator across the power pins of the inverter to stabilize it's power supply.
I also doubled up the second stage to handle powering the toslink module better.
Connect pin 3 to pin 5 and connect pin 4 to pin 6.
Picure of completed module
Hope it helps someone.

To be straight up front I know nothing of electrical ?stuff? beyond not using a hair dryer in the bath.
I have pieced together the following steps to provide a TOSLINK output for the K8NGM2-FID motherboard. The following is 100% based on the schematic from http://www.taligentx.com/projects/opticalconverter/.
The K8NGM2 pin definitions for JUSB1/JUSB2 and JSPD01 can be found in the manual on pages 2-19 and 2-23. Pin definitions for the Inverter referenced can be found at http://us.st.com/stonline/books/pdf/docs/2135.pdf.
Key Components (not including TOSLINK transmitter):
1x 0.1uF ceramic capacitor
1x 74HCU04 hex inverter
1x 10k ohm carbon-film resistor
Steps:
1) Connect TOSLINK GND to JSPD01 GND (pin 2)
2) Connect TOSLINK VCC to JUSB1/JUSB2 VCC (pin 1 or 2)
3) Connect TOSLINK VIN to INVERTER 2Y OUTPUT (pin 4)
4) Connect INVERTER GND (pin 7) to GND wire
5) Connect INVERTER VCC (pin 14) to VCC wire
6) Jump INVERTER 2A INPUT (pin 3) to INVERTER 1Y OUTPUT (pin 2)
7) Connect INVERTER 1A INPUT to CAPACITOR
8) Connect CAPACITOR to JSPD01 SPDIF OUT (pin 1)
9) Connect RESISTOR to INVERTER 2A INPUT / INVERTER 1Y OUTPUT wire
10) Connect RESISTOR to INVERTER 1A INPUT / CAPACITOR wire
I am hoping that someone more knowledgeable can look at this and say 'no way... you forgot x'. And maybe that person could answer a few questions too...
Is it a good idea to place a fuse in here somewhere? If the MB sends more that 5v wouldn?t the wires melt / catch fire? Can someone more knowledgeable explain what the purpose of the resistor is? I understand what the capacitor does, I am a little fuzzy about the intervter?s true purpose ? and I really have no idea what the resistor is for ? or why it is in that spot. Also, the site i referenced said something about connecting the reamaining INVERTER INPUTS to GND to limit interference? huh? ;-)

I have had some success recently with eliminating the high CPU usage (caused by hardware interrupts) which appears after Standby (S3) or hibernate.
I have SATA raid with mirroring, so I have been forced to use the Nvidia IDE and RAID drivers. In addition to the two SATA drives, I also have an IDE hard drive and an IDE DVD.
I have XP installed on both the IDE drive and the SATA drives.
When I boot the system with the C: drive on the IDE drive, the high CPU usage almost always occurs after Standby S3 or hibernate.
When I boot the system with the C: drive on the SATA drives, the high CPU usage is more rare, but still occurs.
Yesterday, I made a small change which I will explain below in more detail, and the high CPU usage has not appeared, even when I boot to the IDE drive. I have gone in and out of Standby and hibernate all day long and the high CPU usage has not reoccurred.
I am hoping I have this problem fixed. However, given that this high CPU usage can be an intermittent problem, I wouldn?t be surprised if it reappears after being dormant for a while.
I would appreciate if someone else with this problem could try the steps below and see if it makes any difference for their system.
If you go into the Device Manager, under the ?SCSI and RAID controller? branch, you may see three entries when RAID is enabled in the BIOS:.
NVIDIA MCP51 Serial ATA Controller
NVIDIA MCP51 Serial ATA Controller
NVIDIA nforce(tm) RAID Class Controller.
I have my two SATA hard drives on the SATA 1 primary and secondary channels. I have SATA 2 primary and secondary channels disabled in the BIOS under RAID setup. However, even though I have the SATA 2 primary and secondary channels disabled, I still get this second ?NVIDIA MCP51 Serial ATA Controller? listed in the Device Manager. If I open the properties on this second one, there is nothing to adjust, it is mostly blank. In contrast the first ?NVIDIA MCP51 Serial ATA Controller? entry shows both my SATA drives under the primary and secondary channel tabs.
This second entry did not appear to have any purpose. So I went ahead and right-clicked on it and hit disable.
Since I did this, I have been able to use Standby S3 and hibernate without any problems.
The system also seems to go into Standby or hibernate faster.
Since I have had this high CPU usage problem since Christmas, I am glad it is gone. I just hope it is not a temporary fix.
If this fix works for others, I will let MSI know. I contacted them a couple of times on this issue, but their only suggestion was to use the latest 3.20 BIOS and the latest Nvidia drivers which didn?t fix the problem.
If this solution does fix the problem, I am guessing that the presence of the second ?NVIDIA MCP51 Serial ATA Controller? entry when there are no SATA drives connected to the SATA 2 primary and secondary channels confuses the Nvidia IDE driver during Standby or hibernate.
For those systems that don?t have any SATA drives and are still getting the high CPU usage after standby, you could disable both entries. Also I think if you disabled RAID in the BIOS, that will prevent both of these MCP51 Serial ATA Controller? entries from appearing. Also as discussed previously, you could uninstall the Nvidia IDE drivers.

I am hoping I have this problem fixed. However, given that this high CPU usage can be an intermittent problem, I wouldn?t be surprised if it reappears after being dormant for a while.
I would appreciate if someone else with this problem could try the steps below and see if it makes any difference for their system.
If you go into the Device Manager, under the ?SCSI and RAID controller? branch, you may see three entries when RAID is enabled in the BIOS:.
NVIDIA MCP51 Serial ATA Controller
NVIDIA MCP51 Serial ATA Controller
NVIDIA nforce(tm) RAID Class Controller.
I have my two SATA hard drives on the SATA 1 primary and secondary channels. I have SATA 2 primary and secondary channels disabled in the BIOS under RAID setup. However, even though I have the SATA 2 primary and secondary channels disabled, I still get this second ?NVIDIA MCP51 Serial ATA Controller? listed in the Device Manager. If I open the properties on this second one, there is nothing to adjust, it is mostly blank. In contrast the first ?NVIDIA MCP51 Serial ATA Controller? entry shows both my SATA drives under the primary and secondary channel tabs.
This second entry did not appear to have any purpose. So I went ahead and right-clicked on it and hit disable.
Since I did this, I have been able to use Standby S3 and hibernate without any problems.
The system also seems to go into Standby or hibernate faster.
Since I have had this high CPU usage problem since Christmas, I am glad it is gone. I just hope it is not a temporary fix.
If this fix works for others, I will let MSI know. I contacted them a couple of times on this issue, but their only suggestion was to use the latest 3.20 BIOS and the latest Nvidia drivers which didn?t fix the problem.
If this solution does fix the problem, I am guessing that the presence of the second ?NVIDIA MCP51 Serial ATA Controller? entry when there are no SATA drives connected to the SATA 2 primary and secondary channels confuses the Nvidia IDE driver during Standby or hibernate.
For those systems that don?t have any SATA drives and are still getting the high CPU usage after standby, you could disable both entries. Also I think if you disabled RAID in the BIOS, that will prevent both of these MCP51 Serial ATA Controller? entries from appearing. Also as discussed previously, you could uninstall the Nvidia IDE drivers.
