P965 Platinum JPWR3 4 Pin Molex Connector

The manual states that this connector is required for stable operation of PCI express graphics card.  I have a radeon x1950 pro 256 based card connected, it's the only card and I have a 6 pin pci express power connector connected to it.  I have been running without plugging into the JPWR3 connector in games.  So why would I need to plug into it?  And what am I risking by not plugging into it?  What does the power provided by that connector do?

You can use it even though your graphics card does have its own 6-pin connector.  That way you have more "backup" for you graphic adapter.  It doesn't hurt at all to use it.
I am also having the 1950 pro and I use both connectors without any problems.  My board is a different one, but the function of the 4-pin connector is the same.

  • I CANT FIND A 4-PIN MINI MOLEX CONNECTOR

    I installed a USB 3 interface. It requires a 4-pin mini molex connector. I have an available connector but it isnt long enough so I need an extension. I did and exhaustive internet search. Cant find it anywhere.
    I would appreciate any help. Thank you.
    R

    Look for a 4-pin molex to 4-pin mini molex converter.  That should fix the length issue (assuming you have an unused molex connector) since I do not believe an extension even exists for these types of power connectors in the first place.

  • P965 Platinum Power Connections

    I am building a new system with a P965 Platinum, Core 2 Duo E6700 and MSI NX8800GTS video card.  On the board there is power connector, JPWR2, which is an 8 pin connector with 4 of the pins covered with tape.  My PS (Antec NEOHE 550) has both a 4 and a 8 pin cable.  Why are 4 pins of JPWR2 coverd and should I use the 8 pin cable?  Also the JPWR3 connector says it is for the graphics card but the NX8800GTS has a 6 pin connector on the card.  Do I need to put power to both JPWR3 and the graphics card?

    Quote from: gbjbany on 31-December-06, 00:34:09
    I have a related question. The JPWR3 connector is a molex plug. Can i just use one of my molex 4 pin power cables or does it need to be the 4 pin 12v connector with an adaptor ?
    I have a geforce 7600gt oc and it doesnt have a power connector, So im not even sure i need JPWR3, i found in a web review that it is only neccesary if running 2 video cards, but that was not confirmed from any other source.
    Appreciate the help.
    "Can i just use one of my molex 4 pin power cables"
    yep, no need any adapters. grab one free from the PSU and connect it.

  • P965 platinum wont turn on

    2GB OCZ gold PC6400 ram 5-5-5-15
    WD25000KS 250 GB 16mb cache hdd SATA 2
    ok  so ive connecte all my parts up into my case with all the molex connector connected and the 8 pin 12 v connector connected with the older 4pin connector. when i turn on the computer the fans all start spinning and then about 2 seconds later they all sop and the power led goes out and then they all come back on again and then 2 seconds later turn of again and it keeps going on in this loop until ti turn the psu off.  iver tried reconnecting all the power leads, removing the hdd and the video card (to insure itsnot a lack of power) and chaniging the slots the rams in (was orininally in slots 1 and 3).  also the dled shows RRGG when the fans spin if thats any help.
    any ideas

    well i sent it back to the place i bought t from for a replacement   and now basically(bar lasts a bit longer beofre restarting an dled is diff) same thing is happening with the replacement mobo ...  what i wrote to msy support:

    when i turn on the computer it starts up for about 4 - 7 secs and then will turn it self of, and then as soon as the fans have nearly stopped it will start again and then do the same thing over and over again until i turn off the power on the psu.    the lights on the dled will be GGRR for half a second and then will go RRRR until just before it stops and then be GGRR agin until it stops (split second).  i had a similar problem when i first installed everything but the dled always stayed GGRR and it would be about 2 seconds before it stopped instead of around 5  seconds.  then returned the unit and as soon as i recieved the replacement this has happened.
    ohh and i think its prolly not the ram cause it still ha[[ened even if i removed the ram .. got no other ddr2 ram to test with tho unfortunatly

  • P965 Platinum has power but not for long - newbie error?

    I press the power button and the PSU and CPU fan spin up for a second then shut right down. No beeping or anything. I removed all other components - mobo outside of case w/ 24-pin power, CPU power and CPU fan plugged in. Same result with or without RAM, with or without graphics card. D Bracket briefly shows all 4 lights when power is supplied. What's up? I'm a total newbie to assembling computers - what am I doing wrong?
    I tried removing the CPU power and when I do that the PSU fan (and light) comes alive and stays alive when I press power. So it seems PSU is good.

    Yes, you should see a 4 / 8 pin connector near the CPU bracket area where you can plug the molex connector to. Change tha 8 pin out for the 4 pin connector.
    Why change the 8 pin out for a 4 pin?
    Make sure CPU is seated properly. Try with vid card and 1 stick of ram only. I would suggest motherboard out of the case but you say you are doing that.

    Please help me Im lost.
    Kind regards

    Some more questions in addition to that:
    1. Did you plug in all power connectors properly?
    ----> 24 pin (board)
    ----> 8 pin (2x (2x2) pin) +12V CPU (board)
    ----> 4 pin (molex) PCIe (board)
    ----> 6 pin +12V PCIe (video card)
    2. Can you give a little more information about your power supply, I found two different power supplies on the NorthQ Web Site that have similar modell names.
    ---> How many +12V rails does it have and what is amperage limit on each rail?
    - The NorthQ site lists a power supply called 4775-500S Giant Thunder and in a note it says: 2 * 75Watt PCI-Express line. That means only about 6A for the video card only on the 6 pin PCIe connector.  This may be too weak.  Make sure you are using the board's PCIe connector as well.
    3. If you can't boot your system it is of course impossible to have a look at the BIOS Version.  If you are unlucky, the board came with a BIOS Version prior to v1.4, which means that your CPU may not be supported with the current BIOS.

  • Power problems... P965 Platinum

    So I updated my system with new motherboard and CPU.
    Case: Sonata Antec II Piano with Smartpower 2.0 450W
    Motherboard: P965 Platinum
    CPU: Core 2 Duo E6600
    MEM: 1x 1GB 800MHz
    I was short of money that's why I only bought certain new parts.
    After installing the mobo and CPU, I plugged in the main power cord to the PSU and switched the power on from PSU (but not from the power button on the case) and the case and cpu fan started spinning and the DVD-drive can be opened and closed. Now this is weird as the computer is not on yet. When I do press the power button, the leds indicates that the system is on but nothing happens (the fans and dvd-drive are still working). So I think there is bad cabling etc.
    I tried re-installing everything but the same thing happens again. Now I have only the CPU + heat sink, graphics card (geforce 7300), RAM and the D-bracket installed.
    The cabling goes like this:
    the 24-pin power is plugged to JPWR1
    the 4-pin power is plugged  to JPWR2
    the 4-pin power is plugged to JPWR3
    the reset switch, power switch and  hdd led are plugged in to JFP1
    the speaker and power led is plugged into JFP2
    the D-Bracket is plugged into JDB1
    So does anyone have ideas why the fans start spinning when I switch the power on from the PSU switch? Have I missed something I need to do in order to make the system work? I've done everything exactly like the manuals tells me to do (I'm writing this from school, so I do not have access to the system, hopefully I remember the cabling correctly).
    thx

    > hmm.... did you save the BIOS settings before?
    Nope, I'm not able to save the BIOS Settings at all. No matter what the settings are (Defaults, modified,...), After saving the settings, the computer just won't boot. I need to clear CMOS in order to get back into BIOS after saving the settings.
    I think this might be caused by the fact that it saves the FSB to 266MHz (1066MHz) (during boot it displays the message that "266mhz system bus processor is not supported <....> System will use reduced 133MHz bus instead.) So after saving the settings (and FSB to 266MHz), the system is unable to boot. I cannot change the value to 133MHz from BIOS (this is what I tried, so that I would be able to test if the FSB setting is the one that makes it impossible to boot after saving BIOS settings), it can be only between 200-500MHz.
    I'll test more powerful / other PSU in couple of days, MSI's support suggested that. Hopefully that will solve the problem.

  • MSI P965 Platinum ATX2 query?

    Hi I have recently purchased the MSI MSI P965 Platinum and have a 600W Zalman atx2 PSU (zm600hp) the PSU as a 20+4 pin connecter to be compatible with the 20pin and the 24pin slots and has a warning on the +4 pin part of it not to connect with atx12V connector? or will damage my cpu/motherboard, now I am not game to turn it on until I can confirm what should be plugged in here? (Could be just the bad translation on the cable that is confusing me with the wording of the warning)
    According to MB manual it pretty much says make sure everything is connected? So is it best to have the 24pin atx2 connector, the eps12v 8pin (2x4pins supplied for this by zalman) connected for power to psu, and the pci express 4pin power connected all at same time?
    Also I am getting soon a Geforce 8800GTS 320MB soon, Am I supposed to have the 4pin power connected to the pci express connector on the Mboard and another pcie power connector hooked up to the video card at the same time? or is it only one or the other?

    OCTO, kindly list out your full system specs, so we can provide you better advice. (read the moan guide).
    For the 2x10 vs 2x12 pin ATX cable, you can safely plug in 2x10 cable to the 2x12 ATX connector on the board. Your board will function normally. The reason of having 2x12 connector (increasing 4 pins from 2x10) is to provide a feedback path of +12V, +5V, and +3.3V (and GND) from the board back to the PSU. Of course the PSU should design the PSU to take these extra 4 pins (4th pin is ground) as feedback. If not, then it's also no harm as it also increases the copper of +12V, +5V, and +3.3V rail from the PSU to the board, providing more current flow.
    No harm it is.
    For the eps12v 8pin, check the wires, they are all yellow (+12V) and black (GND). This is specifically for the CPU. If your board only has 4-pin CPU ATX12 connector, this 8-pin should also fit in (there is only 1 way to plug the cable in).
    For the 4-pin connector near the PCI express, this is optional. You may not need it. but if you have problems with USB devices drop off, your PCIe display card keep hanging or it doesn't have its own addtional power connector, then you need to plug this 1x4-pin connector in for better power.

  • P965 Platinum Dead in the Water

    I have just upgraded to the above MB with core 2 duo E6600 processor. I cannot get any sign of life out of the computer. I have carried out the following checks:
    -Mains voltage gets through to the PSU and the fuse is OK
    -The 20 Pin ATX connector is properly plugged in, shifted towards pin No 1
    -The front panel power switch works (checked it for continuity), but I also tried shorting the contacts on JFP 1 (pins 6 and 8).
    -Reset the CMOS by removing the battery.
    When I push the power switch absolutely nothing happens - no beeps, no sign of life. Has anyone any suggestions for something else to try?

    Slaydeuk you are not alone. I have upgraded to p965 Platinum mobo, E6600 processor and 2x1GB OZC Platinum Rev.2 memory. And I have exactly the same problem as you. My PSU is Antec TPII 480W - http://www.antec.com/specs/TPII480_spe.html. I have tried everything… Now I suspect its either dead mobo, or underpowered PSU. Today I ordered Zalman 600W - http://www.zalman.co.kr/eng/product/view.asp?idx=223&code=015. Hopefully it will arrive during next week.
    Do you guys think my 480W is not enough, or is it a dead mobo?
    By the way Slaydeuk, do you hear any sound from your PSU?.. I can hear a strange sound after I plug in the PSU. You know this electrical buzz sound.. I hear nothing on my older rig, with the same PSU. Can this sound mean anything?

  • P965 Platinum, Vista, and Raid

    I spent a good couple of hours skimming the boards yesterday trying to set up my two new 320 SATAII hard drives in a RAID array.  I ran into a ton of trouble, but then finally figured out part/all of my problem and got things working.  I figure this information will be helpful for anyone who is trying to do the same.  I'll post the most useful links I found at the end of this post as well...
    heres what i'm working with:
    MSI P965 Platinum
    2gb OCZ DDR2 800MHZ 2 dimm kit
    36.7 WD Raptor SATAII (as system drive)
    Intel Core 2 Duo E6700
    Sapphire X1650 PRO 512MB PCI-Express
    Antec TruePower TRIO 650 650W Power Supply
    promise technology ultra ata 133 tx2 (the source of a ton of trouble)
    originally i had vista ultimate x64 installed on a 36.7 gb raptor that was performing ok (once i did the extremetech suggested reghacks for lowdiskspace and 8.3ntfsfilenames), but not as well as my friends new computer with a blazing fast 500 gb stripe.
    my bios was configured as such:
    on board raid controller: ide
    on chip ata devices -> sata 1 config: enhanced
    ...configure sata 1 as: ide
    ...sata 2 configuration: enabled
    i shut down the computer, and changed
    on chip ata devices -> configure sata 1 as: raid
    then i was able to get into the raid setup with Ctrl + I, and set up my array.  Here's where I ran into my first problem.  I figured I wanted a raid 0 because I don't care soooo much about my data being lost, and i have never had a hard drive die on me (knock on wood) in the past 8 years (guardian angel).  So setting up my array was working fine, except for i hadn't anticipated that i would have to choose an ideal strip size.  The board suggests 128k, but after much deliberation I decided since I wanted the speed benefit for my OS and programs, I wanted 32k strip size; but having a 640 stripe for just the OS and programs seems huge, so out of curiosity I tried setting up two raid arrays (both across the same drives).  The first was a 100gb raid 0 with a 32k strip size and the second was a 496.2 raid 0 with a 128k strip size.  This worked fine, but then I got to thinking... can I set up the 100 gb array as a mirror?  If so, then I get the best of both worlds since I can secure all my OS/settings/programs/documents, but I'll have a super fast (respectively) 400 gb drive for ephemeral memory and expendable data (replaceable stuff like ripped dvds, downloaded music and programs, downloaded anything...).  This would all be at the expense of 100 gb which certainly seems worth it at this case because I wouldn't have to worry about the possibility of losing all my data like everyone seems to cry about all over the internet when talking about raid stripes.  So i set it up, this worked fine... next step boot into vist ultimate and start installation.
    Here proved my most annoying step, as my first problem occurred when I couldn't find the dvd/cd drive in the boot sequence menu.  I saw the usb card reader drives, my raid arrays, and my raptor... but no dvd/cd drive (of which I had two connected).  After scouring the web about that darned Jmicron chip, it appeared as if the bios cannot see the PATA drives on this board and I would have to try pressing F8 at the jmicron bios screen.  THIS IS COMPLETE MISINFORMATION.
    As stupid as it is, the real problem is that the boot sequence only displays 6 (i think it's 6) bootable media, and if you have anything else it just doesn't show it.  This gave me the impression that the bios was unaware of my cd/dvd drives connected to the IDE controller.  As soon as I unplugged my card reader, the dvd/cd drives appeared in the boot sequence... thank gawd because...
    i had tried plugging my dvd/cd drives into the promise ata controller (which i already know lacks a vista 64bit compatible driver), which actually allowed me to boot into the vista setup whereupon I was asked (I did NOT have to press F6, even though everyone seems to think they have to) to install the driver for the dvd/cd controller (I assumed and was right that it was asking for the promise ata controller driver).  I put the most recent drivers from their website on a usb stick, plugged it in, and the driver worked and then setup was able to see my dvd/cd drives (which is weird because how did I get to that point if it couldn't?).
    Then setup said it couldn't find any drives, so I figured the problem was with the driver for the ICH8R intel raid controller.  I downloaded drivers from MSI's website, intel's, and a bunch of others, and NONE of them worked.  Setup would install the drivers, but it still could not see any hard drives attached to it.  I'm not sure what caused this problem, but my best guess is that it had to do with the promise card being plugged in. 
    I gave up on that and figured I'd try something else, maybe the promise card was causing the problem.  So I tried changing the ports that all my sata drives are plugged into.  The two new 320's were on 0 and 2, and I also had a drive on 3 4 and 5.  I read somewhere that intel had some array issues on 0 1 and 2, so I tried setting my 320's on 4 and 5 and moved my other drives around it.  This is also when I had the idea to remove my card reader and pull out the ultra ata 133 tx2 card. 
    I was able then to see the dvd/cdrom in the boot sequence, put it first, and boot into vista setup.  VISTA ULTIMATE DID NOT ASK ME FOR ANY DRIVERS AT THIS POINT.  I'm not sure if it was the sata ports I had my drives plugged into or not, but at this point vista setup saw all my drives and I chose the 100 gb array and installation went smoothly.
    Excellent… now I just have to install photoshop and see if it loads in 4 seconds like on my friends new computer with the stripe.  If not, then I'll probably just cry.
    Hopefully I've covered enough of the keywords in this description that anyone who has this problem will  easily find this page.  Remember:
    JMICRON IDE DEVICES CAN BE SEEN BY THE BIOS
    VISTA SETUP DOES NOT NEED ANY ADDITIONAL DRIVERS TO INTERACT WITH THE RAID CONTROLLER
    SORRY IF THIS WAS A TON OF INFORMATION BUT AFTER ALL THE TIME I SPENT TRYING TO FIGURE THIS OUT I FEEL LIKE NO ONE HAD POSTED A FULL BLOWN SOLUTION
    Hope this was helpful

    I have the very same issue except two things. When I try to see why it will not load the Array I find that the first drive (Maxtor 6V160E0) is red and considered to be bad. Did you happen to notice if your system showed the same thing?
    I have moved the drives around and it still corrupts the Maxtor 6V160E0. I have not tried to move them to the end of the SATA connections. I will try that and see what happens.
    Other thing was the JMicron would see my NEC DVDRW, but thought it was a ACSI and it would only read at 12X. It even stated that in the OS. I then was told by the Techs that they have not had alot of luck with NEC drives. So, I purchased a LiteOn SATA II DVDRW, connected it to the JMicron SATA connector and it came alive. I then found it to turn out worthless DVD's and CD's. Not even that Drive would read them after burning. I got so ticked about the JMicron I just shut it off in the BIOS. I hooked up the drive to the #4 port and whala, no more problems with burn. Now it reads, writes, and re-writes at the stated speeds (also I needed to update the firmware twice since I purchase the drive. The MS updates did something to it and the new firmware fixed it.). I have never been able to get a drive to work correctly on the JMicron no matter who made it.
    I sure hope that MSI has scraped any board that will ever use that controller. JMircon is not my friend!
    I am going to get 2 more SATA II drives and try this without having to backup all my data.

  • SCC Box Molex Connector

    I have purchased the SCC box with power option 001 (5VDC supplied by the DAQ board). I assume power will be supplied over the 68-pin cable from the DAQ board, but there is a molex connector on the back of the SCC box that has me concerned. What is the molex connector for?

    Hi Gary,
    Thankyou for posting to the National Instruments Discussion Forums.
    This Knowledge Base explains what different power options are available for the SC-2345 carrier box.
    With the power option you have you can use +5V from either your DAQ board or an external power supply. The external power supply connects at the molex connector and generally a DC apater.
    As such, if you're specific application is running correctly using power from the DAQ board and you do not need extra current, you should be fine with the current setup.
    Hope this helps!

  • No IDE device detected on p965 Platinum

    Hi, I have a p965 platinum and I get the others parts for my new pc (cpu, ram and vga) first, I have to update o the last bios v1.6 to can work with the 1333 bus of the cpu (e675) I update and start ok, but now, I have to install a system, but no detect dvd or hard disk conected to IDE, I was try with a lot of combination of configuration on sata, raid, ide, enchande, disable, etc. but can't fix it. I was read a lot of people with problem like this, or umda on dvd and fix with a bios update. I been update to the last bios, but problem still no fix....any idea?...I'm looking to install windows via network, but one tiime I have windows, I need dvd anyway, so need to fix this problem

    My suggestion is to start from scratch:
    Unplug main A/C power connector from PSU, hit power-on button a few times to drain capacitors and Clear CMOS.  After restarting load Optimizes defaults in BIOS and make sure the JMicron controller is set to RAID:
    Integrated Peripherals --> Onboard RAID Controller --> IDE
    Make sure that the IDE devices connected to the JMicron controller are jumpered correctly as Master and Slave.
    If that does not solve your problem, I suggest you use a SATA HDD and connect it to one of the Intel SATA Ports.  The JMicron controller is a tricky thing and seems to be picky with drives sometimes (especially if two drives (HDD+opt. drive) are hooked up to the IDE port.

  • P965 Platinum IDE/SATA BIOS settings

    Hi all,
    After playing with my system I finally managed to find a proper setting for my SATA hard drive and IDE DVD-RW. If you want to meke this kind of configuration working first of all download the latest JMicron driver from MSI website. Then disable IDE as a master, put the SATA cable to the SATA socket no.1. In this way your DVD/CD will be working as a slave while the HD is a master. In this configuration the time to load windows is the shortest and there is no lag when using the DVD. The transfer DVD to HD is also excellent.
    Good luck.

    Please can you clarify what you mean when you disable IDE as master - is this in windows or bios? ??? The potential bios options are as follows:
    1. On board raid controller
    Setting to IDE : I get the DVD RW Recognised as a IDE device and burning capabilities (windows uses the standard IDE drivers not Intel or jmicro)
    Setting to RAID:  windows recognises the DVD RW as a SCSI device but I don't seem to get any burning facilities with the device (windows uses the jmicro SCSI driver)
    2. On chip ATA devices
    2.1 IDE master enabled  : DVD RW works OK including burning capabilities
    IDE master disabled :  DVD RW works OK but cant burn a disk
    2.2 Setting SATA#1  to ACHI rather than raid Windows hangs (blue screen) during boot up
    Setting  SARA#1 to RAID windows boots OK and hard drive recognised as ATA drive
    (2.2 I know is caused by the fact that I set up the drive as a RAID drive during windows set up so no problem there.)

    I have recently built a Core 2 Duo system based around the P965 Platinum motherboard which I bought based on the excellent reviews it appears to have received.
    My system is as follows:
    Core 2 Duo E4300 with standard cooler
    MSI P965 Platinum
    ATI X1900GT
    1GB Kingston DDR2 667 Valueram
    2xWD 160GB Hard Disks in RAID 0
    Antec Sonata II case with Smartpower 450W PSU.
    I initially tried overclocking to 266FSB which worked flawlessly. All I did was slow the memory slightly so it wasnt overclocked. It worked beautifully, including Speedstep functionality and in SiSoft Sandra beat the E6600 comfortably which runs at a similar speed.
    As soon as I try to go above this speed the system wont boot and all the fans run at their maximum. It doesnt even POST.
    I have tried disabling speedstep etc, and increased voltages slightly. I also slowed the memory further so it is running at 1:1 ratio (532MHz at 266FSB), but I still cannot get past 266FSB.
    Any suggestions?
    I also note that the board does the strange start-stop thing from cold, and if it has been left off for a long time the screen is scrambled when I start it. Any suggestions on these?
    Cheers,
    James

    You're not alone..
    My fighting with this motherboard began the first moment I put my brand new E4300.
    This is the absoluto WORST motherboard in the Galaxy for the E4300, and the reasons, I should explain shortly (I hope someone at MSI is reading this and DO SOMETHING about it)
    The short version:
    There are 3 straps for configuring the speed of each processor on the Intel family.
    the 800 strap, the 1066 strap and the 1333 strap,  these are the straps working on the 4000 and 6000 family of core2
    When you're in the 1066 strap, the motherboard configures the PCI lock correctly and you can safely clock the board from 266 to even 370 or 450 in some cases with the latest BIOS and good MCP voltage... but.
    When you're in the 800 strap like me (all E4300 are in the 800 strap)  the motherboard incorrectly identify the information and it simply DOES NOT LOCK the PCI bus speed correctly...
    Conclusion:  when you excede 266 Mhz speed you already have the PCI clocked so far away from the standard speed, that really is a divine grace that the motherboard boots.. and if it does.. you will have a corrupted HD or you may even lost some PCI card to this.. so... it is really DANGEROUS to set any speed higher than 240-250 for this strap on this motherboard.
    Sure, there are alternatives you may ask... yes,  all gigabyte motherboards and the P5B series correcly identify the 800 strap (200fsb) and Lock the PCI so you can overclock to hell with that one... not on this motherboard.
    There IS an alternative... the alternative is to PIN MOD the processor (remember the Conductive Pen?) to FORCE the motherboard into believeing that you have in effect, a 266 (1066Mhz) processor and then, configuring the strap accordingly..
    well... no.
    It works on the 99% of the motherboards I tried (yes, I did that mod succesfully and unlocked the 1066 strap, booting with 266 bus on a P5B, a 680i SLI and even a 570 SLI motherboard,  with a MINIM clock of 3.2Ghz, what do you think?)
    BUT
    and is a very great BUT,  NOT with this motherboard.
    For some brilliant idea of the MSI engineers, the motherboard start up at 266Mhz and then it clearly tells you that this is in fact a 200Mhz processor,  then, a BIOS halt ocurred and you have a corrupted CMOS setup,  the only way to stop from losing the motherboard is to install another processor and re-flash it...
    so even forcing a 1066Mhz strap is a NO GO with this motherboard that REFUSES to take information from the SAME PINOUT the rest of the motherboard makers follow to regulation and in fact WORKS and reads the information from the clock the processor gives, so.. we are stuck with a NO GO situation.
    The latest bios i tried is the 3.6 bios (BETA) and this problem persist.
    So,  with the P965 the long story became short at the end,  we are stuck in the WORST of the Galaxy motherboard for E4300 overclocking till MSI at least give us the freedom to choose the strap or just use the one that is detected. Until then...  that's it.
    I hope this message reaches MSI,  I work for a hardware page that do reviews and you can imagine what I should say about this motherboard....

    Thanks, that does make sense based on what I am seeing.
    Is there a way of confirming the PCI bus speed is increasing with clock speed?
    This seems like it should be simple for MSI to sort?

  • Apricorn Drivewire HDD Adapter: Old Version Mac Usable?; Molex Connector?

    If you check the specs for this device it does not say anything about Macs. If you check their site their new version includes Mac specs; however, it appears the device is the same and the Mac specs only refer to the fact that the new version now includes free Mac software for hardware cloning and such. Anybody use this "older version: for a Mac?

    Can anyone confirm from the pic link below that the power connector for this is a standard 4 pin molex. I was looking to use the ac power adapter from this UL listed unit with a molex Y splitter to power some external devices as opposed to tapping into a computer. Company site says nothing about if its a 4 pin molex or not.

    Even though one photograph shows (3) HDDs simultaneously connected to the adapter, I think that's for illustrative purposes as to the interface options. In real usage, the power supply would likely not have the output to run three HDDS simultaneously. The determining factor as to how many and what type of devices can be connected to the power supply via a Y-splitter is the DC output for 5 and 12 volts. My $15 (Micro Center) IDE/SATA-to-USB adapter's power supply provides 2,000 mA for both the 5 and 12 volt leads. Unless you can verify that this power supply provides more current than that, I think you can spend less than $35 for an equivalent device.
