KT3 Ultra2 And others HDD max Current

ok peeps, new to this forum, but not exactly new to computing...
i tried MSI with this one, but no reply...
can i safely plug a load of 24mA onto the HDD LED header on my MoBo?  i know this is a 5v line, and as such i am reluctant to put a high current draw on it, as i just know it will make my important 5v voltage a bit wobbly.   should i make a low current switch box to switch the 5v and instead take the current from a 4pin Molex?
incase anyone is wondering, its gonna power 2 TK CoolMod fans, which are 12mA per fan (for the HD Activity LEDs anyway)  i am gonna mod the power lights onto a 4pin Molex anyway, as i really really dont want lots of 5v load...
oh, and i have a 400W  HyperX PSU
there is also, 1 dual channel cold cathode inverter, with 12" cathodes, the 2 TK Smart Fan][s, and a third one on the CPU, two 80mm LED'd case fans (intake) and a cute little CoolerMaster active northbridge fan cooler that i made from an old p3 heatsink i had lying around!

ok thanks for the information.... however i am a total n00b when it comes to even slightly advanced electronics.   i can make switch boxes, and turn LEDs on and off allong with fans and the like, but much past that and i am lost, i can solder very well thou!   ok, if i follow the AND gate route, and i put 5V in one input, and the HDD 3V (or whatever), will i get 8V at the output?  if so, would i have to put 2V in instead, to get my 5V output?
the transistor method also sounds pretty easy, however all the cuircuts i have seen using transistors have had capacitors in them connecting to ground and such like...  is it really as easy as u suggested?  any PNP tranie that can take the voltage and current draw would work?
anyway, you have been hugely helpful so far!  i thought i would have to make a switch box.  i have ages to do this mod anyway, i still havent got my MoBo back from RMA  ;(

  • KT3 Ultra2 and HDD 137Gb

    I wonder if someone can help me to be clear about the following please.
    I understand that there are two inter-related areas with regard to drives that exceed this capacity barrier. One is the need for 48bit LBA within windows to have partitions greater than this size and the other is to have a BIOS that is itself able to address a drive of that size.
    1. As regards the Bios issue, according to this thread https://forum-en.msi.com/index.php?threadid=70205 the KT3 Ultra2 can use HDD >137Gb and would have no probs with a 200 or 250Gb HDD. Is this correct?
    2. As regards o/s issues, I use XP SP1 (intergrated disk). It was my understanding that XP with SP1 was all that was required to run a HDD >137Gb this as per the following threads.
    https://forum-en.msi.com/index.php?threadid=71126&hilight=hard+disk
    http://www.seagate.com/support/kb/disc/faq/137_winxp.html#trad
    However, the info below from MS suggests that one also needs the Atapi.sys version to be 5.1.2600.1135 or later.
    http://support.microsoft.com/kb/303013
    So in my case I have XP SP1 with Atapi.sys version 5.1.2600.1106, therefore I would need to apply Microsoft Knowledge Base article 331958 , referred to in kb303013 above.
    This would in the first instance update my Atapi.sys version to the required one ie v1135 (or later). Am I correct in my understanding please?
    I have not upgraded my HDD yet but would like to be clear on these issues before taking the plunge.

    Thanks for your reply Wonkanoby. I have read several of your posts that say exactly the same thing ie XP with SP1 integrated is fine.
    Any thoughts on what the MS articles are all about. Sorry to ask, but I just get nervy before upgrades.
    Plus I wonder if any other KT3 Ultra2 users can let me know if 250Gb (or any HDD of 200Gb or higher) works on their system.
    Many thanks

  • KT6 Delta/KT3 Ultra2 and MegaRAID SCSI failure

    Greetings,
    Synopsis:
    I have several MSI motherboards and a MegaRAID SCSI 320-2 RAID controller made by LSI Logic. In the older boards (K7D Master and K7T Turbo2), the controller works normally. In the newer boards (KT3 Ultra2 and KT6 Delta), the controller is unable to display its DOS based or "Web" based BIOS.
    I have changed numerous settings in the BIOS of the newer boards but nothing seems to allow me to configure the RAID controller. I also found the following link (https://forum-en.msi.com/index.php?threadid=16821&sid=&hilight=SCSI+RAID) to be interesting. Unfortunately, the suggestions therein did not effect a positive change.
    Details:
    Working boards:
    K7D Master Award BIOS W6501MS V1.1 030502 with 2 AMD Athlon MP 2000+ processors, 1 Gig DDR memory.
    K7T Turbo2 Award BIOS W6330MS V3.3 121901 with 1 AMD Athlon 1200, 512 Meg of SDRAM.
    Non-working boards:
    KT3 Ultra2 AMI BIOS A6380VMS V5.5 071002 with 1 AMD Athlon XP 2100+, 1 Gig DDR 333 MHz memory. PS actual reading: +5=5.030, +12=12.228, -12=-12.071, -5=-5.026. Single 450Watt PS.
    KT6 Delta AMI BIOS A6590VMS V5.5 021004 with 1 AMD Athlon XP 2600+, 1.5 Gig DDR 400 MHz memory. PS actual reading: +5=5.278, +12=12.045, -12=-12.400, -5=-5.277. Dual 450Watt PS.
    The non-working boards work normally without the RAID controller. In fact, they seem to work normally with the RAID controller save that they do not allow the RAID controller to enter configuration mode. They report that - will be executed at the end of POST but they just go to a boot attempt off the floppy drive.
    These same systems (the last two) also do not work with an AMI Enterprise 1400 RAID controller BIOS ver. 1.48 (latest version) or an LSI Logic made Mylex controller.
    Any suggestions on configuration changes, etc. that would allow these RAID controllers to work in the aforementioned motherboards would be greatly appreciated. Further information available if needed.
    -Motherboard type and model: See above.
    -Bios type and revision: See above.
    -CPU type and model: See above.

    I feel your pain buddy !!! it's the same thing for me.  I just got a LSI-22320 and I going through the same troubles.  I was really looking forward to having this nice card in my system, only to find out it would not even let the system boot.  I took the card out and pluged it in my Mom's older than dirt computer and IT WORKS !!... This was a very disapointing experience to say the least....
    Well, if you do here something good, please let me know...
    P.S.  Your SCSI-brother in pain :

    Well, you can waste a lot of time and money trying to get your old iron up to speed but the sad fact is, even though it may work with Color, it will most likely end in a less than satisfactory experience all around. You need to determine if your G5 has PCI, PCI-x or PCIe slots and then purchase the appropriate cards.
    However, Final Cut Studio 2 is optimized for the Intel processors. You will see users here and there using the newest models G5 with great success but quite honestly, you need a Mac Pro.
    Or just purchase the Aja IO/HD which is a firewire 800 interface and the only firewire device that will preview externally Color.

  • Help...KT3-Ultra2 and Hard drive problems

    Hello, I'm new to this board.  I've been having an issue with hard drives lately.   I have an MSI KT3-ultra2 with the latest BIOS version installed.  I recently had a hard drive get completely erased and the actually size of it (10gig) had changed to 1 gig.  Just prior to that I got a corrupted file error in a game I was playing.  (The 10gig HD was a storage drive).  My main drive (Maxtor 40gig) started to clunk and whine and then eventually the computer would lock up hard.  I assumed the HD was going bad and was the cause of all the corruption.  So I went and bought a new WD Hard drive 80 gig.  Had it for about 2 weeks now and now all of a sudden I'm getting a similar clicking noise and a whine and then it locks up on me.  I can only run my computer for about 10 to 20 minutes before it locks up.  I have changed IDE cables to see if they were the cause and that didn't solve the problem.  I've also disconnected all my CD drives and still nothing.  I am going to take a guess and assume there is something wrong with my MB.  IDE controler perhaps?  Can anyone help me with this or confirm my thoughts on the situation?  Any help is greatly appreciated.  Thanks

    May be your powersupply is faulty. Or the memory? try to get it checked

  • Best BIOS settings for Kt3 Ultra2 and Geforce4?

    Hi,
    Can someone tell me what the best BIOS settings would be for my KT3 Ultra2 running a Geforce4 ti4200?
    I get crappy scores in 3dMark2001 SE and I have the infamous stuttering/crashing problems in 3D games.  I've tried pretty much every configuration of settings and drivers I can think of.  
    I saw on these forums that the Kt3 Ultra2 can be a bit fussy with GF4 cards.  If someone could post the best BIOS settings for performance and stability I'd be eternally grateful.
    Alternatively, email me at [email protected] with them.
    Thanks in advance

    very very similar as far as i can make out

  • KT3-Ultra2 and 2400+ CPU

    I have a new system I built...
    MSI KT3 Ultra2 (MS-6380E) Ver. 1.0 MB
    AMD 2400+ CPU
    Dr. Thermal Extreme SE CPU Cooler w/Artic Silver III
    Antec TruePower 550W PS
    512 Meg PC2700 DDR Crucial Ram (Certified to work with Board)
    Seagate 10 gig HD
    Cardtek GeForce 3 Ti-500
    NetGear 100 meg NIC
    Sound Blaster Audigy2 Platinum
    System booted and loaded XP fine.  The original bios was 5.5.  The cpu comes up as 1800+ by default.  According to MSI web site, to adjust for 2400+ cpu, you set the FSB to 133 and the multiplier to 15.  If you do this, the system locks.  If you change to FSB133 and keep default multiplier it locks after reboot (will not post).  Is there a physical jumper on the board I need to adjust/set?
    If I reset back to defaults the system runs perfectly fine...

  • KT3 Ultra2 and Win2k Bug

     ;(   I recently had to return my KT3 Ultra board.  Well, not too recently...it took a month.  But no biggie, they sent me another.  My reseller went bankrupt so I dealt directly with MSI, and they were very profesional.  
    They sent me a KT3Ultra2.  
    I just plugged all my hardware up as it was, and I was going.  But after a day I have started to notice a problem that is so fiercly aggravating that I am going to chew my arms off. here we go:
    *I am running windows 2000 pro.  SP3.
    *I have an Athlon 1800+,
    *1 Maxtor 40GB Hard drive
    *ATI 32MB DDR Graphics card(name escapes me, i'm an audio nerd)
    *M-Audio Audiophile 2496 soundcard
    *M-Audio Oxygen 8 Midi controller connected to onboard USB(not the bracket)
    *I am using a PS/2 mouse and kbd.
    *1 generic MAG monitor
    while running windows, under a load or not under a load, after about 15 minutes at the most, my mouse will lock.  the keyboard still works, and the CPU temperature and usage do not increase.  My Midi controller still works.  In short, everything runs great, but the mouse just won't last past a few minutes without gagging.   X( And yes, I know the mouse works because I've swapped it with others
    I have APIC turned off in the BIOS, quickboot disabled, and my FSB set at 133MHz, but no other changes have been made.
    I don't hae the manual for THIS board, only the last the Ultra, but the BIOS appears identical.  I have the optional D-Bracket connected at the point I connected it on the other board.   is this the problem?  The LED readout was so helpful....anyways, if anyone here has any advice or help, I would really appreciate it.  I'm at a loss.  I've done a clean install of windows 2000, and other than optimizing for background services and turning ACPI off(necessary for midi-latency reasons), no changes have been made to it.   My previous installation of Win2K did the same thing.  

    no, one is a generic logitech wheel mouse, the other is a microsoft intellimouse.  I had no problems with this on the last board.  how are these two boards different?

  • After Installing Windows Updates (7-20-214) chckdsk now runs at start-up and other HDD errors are popping up.

    On 7-20-2014 I installed various windows updates. Later that day I shut down my computer and after a few hours powered it back on. At this point my system started running chkdsk and was unable to read portions of the disk.
    After it went through all 3 phases it booted up fine. So I ran two tests. A Seagate HDD tool for windows and ran activeSMART tools. Both of them said there are errors to my HDD and that I should back up and get a new HDD.
    It just doesn't make sense that in the span of a few hours my otherwise perfectly fine working HDD would send back all of these errors. There are no sounds coming from the drive to indicate mechanical failure, and otherwise I have no problems using the system;
    no slow downs opening files etc.
    Please if anyone knows of any current Windows Updates that could be causing this I would very much like to know as that is one of the only things I can think of that could be causing these errors. Thank you.

    I agree with Frederic. In addition to this: Do not hesitate and backup your data, buy new disk and make new installation. If you have problems with retrieving some files, use program
    Recuva.
    Not all HDD failures are accompanied by noise. Imagine failure of hdd electronics. Not all mechanics stop functioning with noise.
    I have never experienced any update problem that had caused mechanical failure. Perhaps large disk activity during updates accelerates the disaster process in your computer.
    In my personal opinion the "low price goal" is behind the higher failure rate. For disk vendors it is cheaper to replace several failked disks than do thorough test of all disks (or memory, etc.) I had mechanical disk that ended its life in
    two months... (Do not be fooled by large MTBF values. These are extrapolated data from hdd sets.)

  • Problem: KT3 Ultra2 and DMA mode

    hi there,
    everytime i wanna make an image of a CD with nero or some other CDR progs, it takes years to finish it. i got only a tranfer rate of 800kb/s - 1.400 kb/s (btw: there is no copy protection...this happens even on normal data cds)
    i got my HDD and CDRom on IDE1 and my CDR and DVDRom on IDE2
    in winXP it tells me:
    IDE1:
    0: UltraDMA Mode 5 (Hdd)
    1: PIO
    IDE2:
    0: UDAM Mode 2 (DVDRom)
    1: MultiwordDMA Mode 2 (burner)
    CD Rom Teac CD-540E Firmware 3.0A (IDE1 Slave)
    Burner Benq CD-R/RW 24x10x40 Firmware P.QJ (IDE2 Slave)
    DVD Rom Pioneer 104 Firmware 2.06 (IDE2 Master)
    i tried to reinstall the latest via drivers but nothing worked.
    sometimes winXp tells me
    that IDE1 device 0 is running in udma 2 mode...but than on the next reboot it's again on pio mode.
    i checked the ide cables and changed the CDrom with the CDr and it show me UDMA2 now...but it didn't speed up the transfer rate...it still runs only with ~1.400kb/s :(
    maybe the ide cables are corrupt???
    apart from that i tried the latest bios drivers for my Mainboard but they didn't seem to solve that prob.
    are there any options to check and enable the DMA mode on both IDE channels?
    hope someone can help me

    Kt3 Ultra2 + Duron 1400MHz + bios 5.7 works correctly.
    And from user letoii:
    Quote
    these chips work fine, in anythign that supports a thoroughbred     Go to the top of this page
    these chips work just fine. they just are not detected as a proper duron 1600 or what ever. they will detect as an Athlon XP 1900+. Make sure to set the FSB to 133mhz.
    These are boards that I have used the chips in:
    K7T Turbo2
    6378V3
    Kt3Ultra
    Kt3Ultra2
    KT4Ultra
    KT4AVL
    745Ultra
    and a bunch of others
    i think that MSI just doesnt want to update the BIOS for all their old boards
    sos that the CPUs are properly identified.
    So looks like there is a godd chance that it will work (kt3 ultra2 and kt3 ultra2-c a nearly identical exept missing ram bank and missing raid controller - but they use the same chipset).

    I think so, see above.

    Just wanted to let you know that I have experienced the same characteristic on a Kt3 Ultra2 and onboard audio.  I have also noticed a similar situation with Windows XP using a Creative SB Live 5.1 on a K7M mobo and a Santa Cruz sound card on an A7V333 mobo.
    I will also be interested in finding out how to make a change to enable controlling the audio level on the analogue CD ROM input.  I believe it is a Win XP issue and not an issue with the KT3 Ultra2 onboard audio or its associated driver.

So turn off the system without do any thing ,let rest 10 minutes & turn on, the hard disk  can detect ,so go to windows  again, try play cd  again, but after this the system was not  respond same like above problem .so reset the pc ,after booting the computer can not detect the hard disk again. So I turn off and  until  today in morning .I turn on my pc,after booting the hardisk can detect.but can’t go to window anymore, because all inside my hdd
    was lose, my D Drive data also missing (I got 2 partition-1st partition-C Drive: OS+ Software; 2nd partition -D Drive :MP3 song +My document).But I go to FDISK ,can’t access drive.
