Disabling JMicron on 975x PUE?

Hey all,
I was reading some 975x PUE overclocking tips in the OC forum a few weeks ago, and it said something about disabling JMicron. When I went to go do that, I couldn't figure it out...
I'm on BIOS 7.4, and it seems that JMicron is doing nothing for me except slow my boot... does anyone have any quick tips?
Thanks

The JMicron Chipset/Controller is there to offer you a 2nd IDE-port and a 5th SATA Port (that is all it does). If you don't need any of these two ports you can safely disable that thingy.

RAID1 on 975X PUE

Hi,
I have the following computer:
E6600
4 x 1 GB GSkill RAM
Nvidia 8800 GTS
975X PUE
I just purchased two 500 GB Western Digital drives to do a RAID1 setup. I would like to do two partitions on them and split the space somewhere around 150 GB / 350 GB and mirror that to the other drive.
Is there a guide to do this? Any tips?
If I remember correctly, I have the 7.2 BIOS and cannot switch it because otherwise my RAM will stop working and I don't have different brands and timings of sticks to boot up if it fails. I have 4 GB RAM, but Windows only recognizes 3. If anyone knows how to solve this as well, I'd appreciate it.
Thanks!

One last question, at what point should I partition the drive?
After your array is properly set up, you should be able to to partition it like a regular hard drive.
Quote
Will it automatically partition the other one as well?
Yes. If everything works correctly and the partitioning software you use supports your Intel ICH7DH RAID controller, the array should behave like a regular hard drive. Basically, it will be considered as one single disk drive.

Is there any way to double check to make sure my RAID 1 is working and mirroring everything correctly?
Install Intel® Matrix Storage Manager as soon as Vista is up and running. You should be able to find it here:

Btw, my BIOS is 7.1, NOT 7.2
Well, that should allow you to re-activate your JMicron Controller without problems.
Did your install the 64bit version of Vista?

Favor to persons with bios 7,6 on 975x pue

Blank I would want to ask the persons who have the 975x pue with bios 7,6 to activate the jmicron in ide in order seeing if she works with chip intel.
Thanks to all those who will make this pleasure me.

Okay Lucabis, here is my test report:
I am using BIOS 7.61 BETA.
I have no drives attached to the JMicron ports, but I enabled the JMicron Controller in BIOS.
I have two SATA hard drives connected to the Intel ICH7DH Controller in Non-RAID mode, and I switched the Intel Controller to RAID mode in BIOS.
After that, I rebooted the system. The RAID BIOS status screen appeared and my two SATA Drives were listed as non-RAID disks. I was able to access the RAID BIOS by pressing <CTRL + I> without problems.
I will not go any further with this because I don't want to risk data corruption. If this sounds like it is worth a try, please go and test it yourself.
Now, let's try Yahoo Babel Fish on this one (Italian you said?):

Lucabis giusto, qui è la mia relazione sull'esperimento: Sto usando l'ESSERE VIVENTE 7.61 BETA. Non ho azionamenti fissati agli orificii di JMicron, ma ho permesso il regolatore di JMicron nell'ESSERE VIVENTE. Ho due SATA che gli azionamenti duri collegati al regolatore dell'Intel ICH7DH in Non-non-RAID il modo ed ho commutato il regolatore dell'Intel al modo di INCURSIONE nell'ESSERE VIVENTE. Dopo quello, rebooted il sistema. Lo schermo di condizione di ESSERE VIVENTE di INCURSIONE è comparso ed i miei due azionamenti di SATA sono stati elencati come non-non-RAID disc. Potevo accedere all'ESSERE VIVENTE di INCURSIONE premendo senza problemi. Non andrò affatto avanzare con questo. Se questo suona come esso vale una prova, prego va verificarlo voi stessi.

MSI 975X PUE weird temps

I recently bought a 975X PUE, but I get really weird temperatures. With the DualCoreCenter app I get 42C idle. Speedfan, it displays from -125C to 90C at any time. In configuration I changed from PII diode to thermistor diode. That seemed to keep it at -25C. With Core Temp Beta 0.94 Core #0 and Core #1 I got 51C-52C idle. I am using the Intel stock cooler and paste. I used the latest version of all the apps stated above. What should I do? The board is brand new and the case has really good air conduction. Also note that I am using SMART Fan, when I disable the feature DualCoreCenter gives me temp 39C on CPU and Core Temp #0 Core 45C and Core #1 44C

Yeah I found most temp progs suck in this mobo/chipset (not sure which it is) - Dual CoreCenter gives a 10c different reading compared to all other progs (no cheating there then!) and the alarm also set off constantly even though tthere were no temp breaches.
CoreTemp has also given me wierd readings.
I use Everest Ultimate 2006 as it seems to be about right (or rather the only one which didnt give wierd readings)

975x PUE & Overclocking Help

Hey guys,
I have an Intel core 2 duo 6600, MSI 975x PUE mobo, 4gb ddr 2 corsair ram. I followed the several guides on overclocking, and currently have my CPU FSB at 333, the CPU Voltage is set at auto (according to PC Wizard 2008 it's running at 1.28V), my ram multiplier is at 1:1, ram voltage is at 2.1, ram timings at 4-4-4-12 Everything so far seems stable, idle temps are in the mid 30's (celcius), however i have one problem, When i restart my PC, the computer does not post, my screen just stays black. I have to reset it again for the bios to post and the computer to boot. Anyone know what causes this and how I can resolve it? I appreciate any help!

First of, PSU corsair VX 550, cracking PSU and single rail. Would say mid budget range.....
Did you set PCI express timings to 100 instead of Auto?
Disabled spread spectrum
Also, disable SPD and maually set to 5-5-5-15
memory voltage as per manufacturers website
Do not up voltage of cpu to start with......
And lastly.......... was system stable before you started OC work?
I researched my PSU and found nothing but great reviews, it's basically the same PSU as the OCZ GameXtream 700W PSU.
PCI Express frequency is on 100
Spread Spectrum is Disabled
Memory Timings are already manually set at 5-5-5-12 as per the manufacturer (I also tried 15 but no change)
Memory voltage is at 1.9 per the manufacturer
CPU Voltage is set on Auto since upping the voltage made no change.
My System is completely stable on default settings, and its' completely stable when overclocked to 3ghz, however when i restart the computer it will not do a warm boot, I have to hit the reset button. It's more of an annoyance then anything.
Right now I have my CPU running at 2.84 and memory at 667 w/multiplier on 1.25 and my computer will do a Warm boot Just fine. I'd really like to keep it at 3ghz though.

975X PUE SATA RAID Windows XP Blue Screen Install

Hi,
I've just purchased a new MSI 975X PUE motherboard and am trying to install Windows on it.
I have connected 2x WD Raptor 36GB drives, and set them up in a RAID 0 array using the Ctrl+I RAID BIOS utility. I have set the SATA config in the BIOS to RAID mode, and turned off the other SATA controller... The RAID BIOS detects the array ok after it has been set up, and shows it as OK.
When I boot from a Windows XP SP2 CD I press F6 and choose the RAID Driver for ICH7R RAID. Windows tells me that it already has a driver but this version is newer, so I say to use the one on the floppy (I have tried without doing this and Windows does not detect any Hard Drives at all).
Once I have loaded the drivers it continues loading the other drivers for the setup, and then gets to "Loading Windows Setup", here is waits for a minute or so and the blue screens.... The stop code is 0x7B (INACCESSIBLE_BOOT_DEVICE)...
I have upgraded the BIOS from 7.0 to 7.1 (not 7.2 yet as I have read about problems with it).
I've tried various versions of the drivers from different locations, and each time it blue screens in exactly the same place... I'm beginning to get very annoyed with this as I shouldn't be expected to find my own drivers when there are ones supplied on the CD...
Is anyone able to suggest what I could do?
Thanks
[EDIT] Also I have tried an install of Windows Vista Beta and that installed fine using the drivers from the CD...

I must say again that the problem is located in the memory modules. As suggested by Hans before, try running memtest86 first,
http://filexoom.com/files/2006/11/1/41824/memtest86%2B-1.65.floppy.zip
and sometimes even if tests runs fine, doesn't mean that memory is OK. It just might be that that type of memory doesn't fit within your MB. As I mention before, my friend was using Corsair for his MB(getting the message INACCESSIBLE_BOOT_DEVICE), and after replacing with A-Data(definitely lower quality memory), everything went fine. So, try with another memory.
As for Murphyman, when you use the yellow connector, you are using the Jmicron controller,witch asks for RAID drivers before you use the device installed on it. The blue IDE controller is controlled by Intel's ICH7DH, and no RAID driver is need. So, try connecting the DVD drive on the blue connector, and see if will work.

HOW TO install RAID/ AHCI 975x PUE Driver Guide

As below on how to install the matrix driver, there is no 'how to install on a system not already preconfigured with raid/AHCI'. This driver creates a F6 Floppy disc, why? because windows will not recognise your hard in AHCI mode without the driver installed. This is why we get a reboot with AHCI enabled. It gets to a point then when windows loads with no driver it reboots. If you try to load the driver first, the hard ware has not been enabled so there is nothing to install. Reinstall Windows is the only way.
* 5. INSTALLING THE SOFTWARE
5.1 General Installation Notes
1. If you are installing the operating system on a system
configured for RAID or AHCI mode, you must pre-install
the Intel(R) Matrix Storage Manager driver using the
F6 installation method described in section 5.3.
2. The 'Intel(R) Chipset Software Installation Utility'
must be installed on the system after a supported
Microsoft* Windows* operating system has been installed.
3. To install the Intel(R) Matrix Storage Manager,
double-click on the self-extracting and self-installing
setup file and answer all prompts presented.
4. By default, all installed files (readme.txt, help, etc.)
are copied to the following path:
<bootdrive>\Program Files\Intel\Intel(R) Matrix Storage Manager
5.2 InstallShield* Installation from Hard Drive or CD-ROM
Note: This method is applicable to systems configured for
RAID or AHCI mode.
1. Download the Intel(R) Matrix Storage Manager setup file
and double-click to self-extract and to begin the setup
process.
2. The 'Welcome' window appears. Click on the Next button
to continue.
3. The 'Uninstallation Warning' window appears. Click on
the Next button to continue.
4. The 'Software License Agreement' window appears. If you
agree to these terms, click on the Yes button to
continue.
5. The 'Choose Destination Location' window appears.
Click on the Next button to continue.
6. The 'Select Program Folder' window appears. Click on
the Next button to continue installing the driver.
7. If the InstallShield* Wizard Complete window is shown
without a prompt to restart the system, click the Finish
button and proceed to step 8. If it is shown with a
prompt to restart the system, click 'Yes, I want to
restart my computer now.' (the default selection) and
click the Finish button. Once the system has restarted,
proceed to step 8.
8. To verify that the driver was loaded correctly, refer
to Section 6.
5.3 Pre-Installation Using the F6 Method
Note:
The Steps 1 and 2 can be skipped if you use the F6 Floppy
disk utility provided by Intel. This utility can also be
downloaded from the following website. These methods
are applicable to systems configured for RAID or
AHCI mode.
http://downloadfinder.intel.com/scripts-df/Product_Filter.asp?ProductID=1809
1. Extract all driver files from the installation package.
See Section 7.2 for instructions on extracting the
files.
2. Create a floppy containing the following files in the root directory:
iaAhci.inf, iaAhci.cat,
iaStor.inf, iaStor.cat,
iaStor.sys, and
TxtSetup.oem.
3. At the beginning of the operating system installation, press F6
to install a third party SCSI or RAID driver.
4. When prompted, select 'S' to Specify Additional Device.
5. When prompted, insert the floppy disk you created in
step 2 and press Enter.
6. At this point you should be presented with a selection
for one of the following depending on your hardware
version and configuration:
- Intel(R) 82801GR/GH SATA RAID Controller (Desktop ICH7R/DH)
- Intel(R) 82801GR/GH SATA AHCI Controller (Desktop ICH7R/DH)
- Intel(R) 82801FR SATA RAID Controller (Desktop ICH6R)
- Intel(R) 82801FR SATA AHCI Controller (Desktop ICH6R)
- Intel(R) 82801FBM SATA AHCI Controller (Mobile ICH6M)
- Intel(R) 82801ER SATA RAID Controller (Desktop ICH5R)
- Intel(R) 6300ESB SATA RAID Controller
7. Highlight the selection that is appropriate for the
hardware in your system and press Enter.
8. Press Enter again to continue. Leave the floppy disk in
the system until the next reboot as the software will
need to be copied from the floppy disk again when setup
is copying files

Well I went for it, RAID that is. I borrowed a 300GB SATA II Seagate Barracuda from work to backup to and got started. I shall layout how I did it for those having trouble.
So my old config was Maxtor SATA II 80 DiamondMax system drive and a Maxtor SATA I 250GB DiamondMax for Data. Now with the 300GB SATA II to backup to and running in IDE mode enhanced with speed disabled in bios. HDTach benchmarking is in above posts for these drives.
I copied all that data I wanted to extra drive and made a boot floppy and copied the files from the 975xPUE CD for the Intel RAID controller.
CDROM:\IDE\Intel\ICH7R\Floppy\32
Now I shut down my system, removed the bachup drive and entered the bios.
*I set back all my setting to default, no overclock.
*Integrated peripherals/Onboard JMB361 mode: Disabled JMicron controller
*Intergrated peripherals/SATA Devices Configuration/SATA Mode/ Set to RAID,
*SATA Port Speed/Disabled.
*Set system to boot from CDrom.
I put in my floppy and the XP CD and rebooted, CTRL +I to enter the Intel RAID setup and first thing I found out was that with my 80GB and 250GB drives in a RAID 0, I was getting 152GB of a logical drive. So I setup the RAID and rebooted.
80GB+250GB=152GB RAID 0 (I have about 200GB backed up, so I going to have to get another drive, SATA II 300 maybe)
Now the system booted off the XP CD and as it started to load, it read the floppy and I DID not press F6. I noticed that just before the setup screen the system loaded the driver automatically from the floppy. And low and behold it recognised my hard drive 152GB and I kicked off the install.
* Note: After Setup had finished formatting the partition, the system loaded the drivers from the floppy again and then started copying files from the CD before restarting to boot from the hard drive. So if you had already removed the floppy, the drivers for the Intel RAID controller would not be loaded and the second stage of install would never get started, blue screen or not recognise you hard drive.
The rest of the install went very quick and I installed all the drivers and NOW for the juicy bits.
Ok so I thought, how am I going to read my backup drive which is IDE/SATA on my system if it is in RAID. So I connected the drive to the Jmicron SATA port 5 enabled the JMicron controller in the bios and set it to IDE.
*NOTE: After I rebooted the Intel RAID had reverted back to IDE so I had to go back into the bios again and set it back to RAID. When I rebooted I got the Intel RAID slash screen and then the JMicon one showing me the 300GB and asking my to press a button to continue. Quite abit of extra startup time with both enabled.
Windows loaded fine and both my C: 152GB RAID 0 and D: 300GB were there, but the 300GB was showing as a removable device! I know there is a reg fix for that somewhere.
Benchmarking: This is the best bit!
Maxtor Diamond 80GB SATA II and 250GB SATA I = 150GB Logical RAID 0 test with HDTach 3, 8mb test:
Burst Speed : 320.9 mb/s
Average Read : 120.3 mb/s
Now that is some difference from IDE enhanced so well worth the effort!
IDE: Burst Speed: 215.3mb/s
Average Read: 59.0mb/s
Now I also tested the Seagate 300GB SATA II drive which is connected to the JMicron controller in IDE mode and the results show that the JMicron does not support SATA II drives but maxes out SATA I: so even if I do buy and extra drive will I be able to add it to the RAID 0 or will I be stuck with SATA I speeds on the JMicrom controller. No doubt I will soon find out.
Seagate: Burst Speed: 150.5 mb/s
Average Read: 50.5 mb/s
Thanks for the tip Insomniac34

975X PUE: SATA vs IDE Combinations: 2+2, 4, or 1+3?

Hello,
I searched but didn't find info. For a new build with a 975X PUE, what is the optimal configuration of IDE/SATA drives. I want to have a configuation like:
DRIVE PURPOSE SATA or IDE?
C: VISTA OS ?
D: Data drive 2 SATA, RAID1
E: Backup for Data ?
My question is: Should I use SATA for drives C and E or IDE? Or one of each? Is there a general rule for which is preferred? All things being equal, I prefer SATA since cables are smaller.
Thx.
Scott
PS C and E will likely be single-drive, non-RAID.

Quote from: jsmartin22 on 16-June-07, 14:51:31
I thought perhaps there would be a difference data rates between the IDE/SATA, which arise only when you reach a specific # of SATA drives--in which case it might be better to begin using IDE. Looks like I was wrong. Thx.
Scott
SATA II 300 has 3.0 Gbit/sec available per port, so the number of SATA ports used should not make a difference. There is a theoretical advantage in using SATA, as it is a serial connection instead of a parallel connection with PATA.
Furthermore, because of your RAID 1 setup, you will be using AHCI mode for the onboard Intel controller. The Intel Matrix Storage driver (used for AHCI mode) might give you a couple percents extra drive performance over an IDE interface, even when using single drives.
So SATA would be the way to go...

MSI 975X PUE + MSI StarHub 7-port USB 2.0 + Windows XP SP3 = Fail

Hi,
today I bought a MSI StarHub and connected it to my computer with MSI 975X PUE and Win XP SP3. But XP does not recognize the hub. On the same computer I have Win 7 installed. There the hub works very well. Any hints to get the hub working on XP? I have same problems with my mouse, logitech G500. It works on WIN 7 and does not work on XP. What can I do?
Regards

There was no driver for the StarHub included and I did not find a driver to download on the msi homepage. When running Win7 the hub is shown as Generic USB Device in the device manager on xp it is a USB 2.0 HUB [mtt] and I do not have the driver for this.
I installed the logitech G500 driver on both, win xp and win 7, but xp does not recognize it.

SATA to SATA transfer speed for 975x PUE

hi guys, i'm using this 975x PUE currently and having this problem. when i tried to copy large data files from a SATA HDD to another SATA HDD it always takes very long time to complete. ofcoz both HDDs are internal and no RAIDS card installed.
eg : copy files about 160GB size take more than 12hrs..
i think it shouldnt take such a long time to copy such huge file. this dont happen to me in my previous pc. can anyone advise pls?

thanks hoshigami, to be honest your pc spec is as good as anyone else but i hope you have sata2 hdd and not sata1 as they are much faster than sata1 when it comes to transferring of data. also i assume your ddr2 is ddr2 800.
when i cloned about 30gb from one hdd to another hdd it took about 25 minutes therefore 160 should not take more than 2 hours in fact much less as cloning is slower process than just copying..
as far as bios is concerned there is no parameter in which it can speed up transfer of data but what you can do is go into bios then click on default setting then click yes and save and exit. and also before copying you defrag your hdd a few times or use speeditup [link below] for further defraging.
http://www.geardownload.com/system/speeditup-free-highly-recommended.html
also do you have FAT32 or NTFS file management., also your hdd 7200 RpM or 5400 RPM.
i think your prob lies with the fact you try to copy 160gb in one go by doing that large chunk of data is scattered on your hdd without being defraged.
i would first copy about 20 to 30gb then defrag hdd a few times then copy further 30gb and defrag....and so on..
to be honest i can not think of anything else . lets see what others have to say. good luck

Speedfan Configuration for 975X PUE !

Does anyone please have a link to where I can download the Speedfan configuration for the 975X PUE ?
Thankyou

Hello Jack The Newbie,
Each motherboard has to be configured differently within the Speedfan settings in order for the software to give correct readings.
The Speedfan website provides configuration settings for hundreds of different motherboards from all manufacturers but not the MSI 975X. I have no idea how to configure Speedfan myself and so was hoping to be able to download the settings from somewhere !

975x PUE random reboots during games

Here is my setup:
MSI 975x PUE
Core 2 Duo E6300
2GB Gskill 800mhz DDR2
X1900XTX (PCI-e)
300GB HDD
Xfi Fatality
Windows XP And Vista
My system seems to reboot randomly when playing games. No warning, No errors, just straight reboot. It could be 5 mins into the game or 45mins into the game. I have tried formatting and reinstalling windows XP Pro, I also tried installing Windows Vista Ultimate, I made sure the voltage in the BIOS is setup correctly for the memory, I run memtest86 for almost 24 hours with no errors, I run Windows MemTest for about 20 hours with no errors, I run PRIME2004 for about 9 hours with no errors, I tried different RAM, I bought a new hard drive, I replaced the Power supply with a brand new Antec 650 watt. I updated the BIOS. There are games which I have played for a few hours with no reboot, Diablo 2, Neverwinter Nights 1, Quake 3, Counter Strike Source. Games that reboot the system all the time are Command and Conquer 3, World of warcraft, Lord of the Rings Online Beta, S.T.A.L.K.E.R, and Neverwinter nights 2. I have also tried installing Ubuntu, and the install goes fine, but I cannot install the video drivers, and I get a PCI error every time I boot up, the error is too quick for me to take a note of.

Quote from: Blazer on 05-April-07, 04:34:35
rma the orig gskill, corsair has always worked for me, kingston hyperX should work also, or just read through the forums for what is working for others, cheaper is not always better, it appears the 975 is picky about ram.
That would lead me to believe the MB is defective then, not the RAM. If the MB is fussy about RAM why would the onus be on the RAM manufacturer to replace the RAM until something works instead of the MB manufacturer, who is the source of the problem, to properly design their MB?
FYI I'm also having issues with my 975x PUE where it won't boot with neither my very high quality OCZ RAM nor with just basic Crucial RAM. They've RMA'd my first board and the new one fixed my original problem (wouldn't even initialize POST) only to give me different problems. MSI royally screwed-up with that board and I hope they find a solution quick because I'm not very enthusiastic about being beta tester for hardware I pay hundreds of dollars for.

Vista Drivers for 975x PUE?

So I've decided I've procrastinated enough and I'm going to install the latest Vista beta. Are there Vista drivers for the 975X PUE yet?

Quote from: Vaniireq on 15-November-06, 12:35:18
I tried Vista beta...
I hated it..
I am a gamer..
I have a good pc and nice graphics card but...
Games run much slower on Vista..
Frame rates are terrible...
Even with the Vista Nvidia drivers, games were terrible..
A word to the wise:
If you play games or do graphic stuff, stay away from Vista since even Microsoft admits that right now, gaming will be slower on Vista...
Hope that helps someone...
Be safe and have fun...
Of course it runs slower. It's a new OS. It takes more resources to run. That's the way it's always been. I remember when XP came out, and everyone was horrified that the minimum was 128, and they didn't understand why everything was so slow on that monster machine that ran so fast under 98.

MS 7246 (975x PUE) = Motherboard of many woes , help if you can.... (pics)

My setup
MSI MS - 7246 v 2.1 (975x PUE) bios 7.0 / 7.1/7.2/7.4
E6600 2.4ghz w/ 4mb cache
2x 1GB Corsair CM2 6400 (ddrII 800)
Silencer 610w powersupply
2x 74gb raptors Raid=0
I'll try to be as informative and brief as possible.
My journey started with a lot (not enough as it turns out) research for a nice board for the core 2 e6600. Finally choosing this motherboard after reading through the review on tomshardware.com . I'm not new to computer building, but who knows, maybe I've missed something.
I've come to find , the bios are quite horrible to say the least, with each "revision" i loose more options and less things work.
This motherboard will not clock my e6600 correctly. In system properties / CPUZ it is displayed as a 1.2ghz proccessor.
The bios also confirms this on boot up, Displaying 297mhz (33x9) along with the incorrect DDR2 533 speed.
Here are the settings in the bios (ver 7.0, the only version that seems to work with the RAID)
CPU FSB Frequency = 266mhz
FSB @ memory clock ratio = Auto (i believe thats 1:2 according to cpuz)
It feels like im missing a multiplier somewhere in the setup. Everything is half speed.
I've tried to update the bios to the one's ive listed , but with any other bios revision my FSB ratio option gets locked, and my raid doesnt work.
I've sent the motherboard in on RMA and its been returned, It came with the 7.4 bios flashed on to it which means my raid wouldnt work (and still would not detect the processor correctly).
I've included some pictures of the bios settings and what its displaying, just to prove im not out of my mind!
Any help would be great!

It seems pretty evident to me that you have a bad board. I've tried all offcial bios (and many betas) and NEVER my processor (the same as yours) was incorrectly detected.
I doubt that dissabling SpeedStep and C1E will help in any way, and if it does, that should be a sign of a faulty board, because I'm running at 3 Ghz (333 x 9) with SpeedStep and C1E enabled and all voltages auto without any problem.

MSI 975X PUE Power Connector !

I've just noticed that the 975X has a 24 pin ATX connector. My Antec Truepower 480W PSU only has a 20 pin connector.
Is this an adaptor available or will I have to dig deep and buy a new PSU ?
If a new PSU, then any recommendations !
Thankyou

Quote
The Antec article is very interesting and basically seems to say that it is OK to use a 20 pin ATX supply on a motherboard with 24 pin ATX connector. This is contrary to the link in a previous post !
Not really. Here is a passage from the arcticle the other link did point you to:
Quote
The 24 pin connector is actually just the 20 pin connector with 4 extra pins added on the end. The original 20 pins were unchanged. The extra 4 pins are not separate rails. They're just extra lines to provide more current to the same rails. On every motherboard I've seen, the extra lines for ground, 3.3, 5, and 12 are just connected to the other lines on the same rail from the 20 pin connector. I've never heard of exceptions and it doesn't make sense for motherboard makers to create any. As a result, you can plug a 20 pin cable into a 24 pin motherboard and it will work just fine. At least, it will for a while. They added those extra 4 pins for a reason. When you plug a 20 pin cable into a 24 pin connector you're not providing the extra current carrying capacity which may be needed by the motherboard. If your motherboard's current requirements are low enough then it will work properly with only a 20 pin power cabled plugged in. But if the motherboard draws enough current, then you can overheat the 20 pins you're using on the 24 pin connector.
Quote
I assume that the 4 pin connector next to the first PCI-E graphics slot on the 975X PUE board takes the same connector/supply as the one that supplies power to the IDE [...] drives !
Yes, it is the same connector you usually use for IDE drives:
Floppy drives usually use this kind of connector:

I've seen the spec. The OCZ I recommended will run his pouter.
It probably will. But I am a little afraid that the 450W-PSU you recommended might come close to its limits on the 26A/+12V-rail.

A couple of fans will need 12V-power as well.
