    Actual Vcore and Vdimm readings

    I measured Vcore and Vdimm using a Digital Multi-Meter. Here's what I got:

    Biostar 6100-939
    CU51MA12 Beta Bios
    Winchester CBBFD 3200
    (Note that the measurements below are valid from the early BIOS up to the Cu51ma20 BIOS)

    Vcore:
    0.875 to 1.375 not measured.
    1.40 = 1.397V
    1.425 = 1.422V
    1.45 = 1.446V
    1.475 = 1.472V
    1.50 = 1.496V
    1.525 = 1.521V
    1.55 = 1.546V
    1.60 = 1.614V
    1.65 = 1.655V
    1.70 = 1.722V


    Vdimm:
    2.6V = 2.64V
    2.7V = 2.73V
    2.8V = 2.84V
    2.9V = 2.93V

    3.3V jumper in place:
    3.3V = 3.33V (This value is PSU dependent)

    Vcore can be measured on the Switching Coils. In the picture below, the coils are above the CPU and it's any right-hand lead...

    Vdimm can be measured on the source of the regulator FET. It's the 1 I have circled...




    Here's a pictorial of the FET. Sometimes the center Drain leg is cut short...

    Which CPU Overclocks The Best On The T6100-939?

    As time passes, I notice every board has it's favorite CPU. Since A64 has been available, it became apparent that each board had a favorite Memory, but only recently have I noticed that a particular board will clock higher only with certain CPU's. Here's what my Biostar 6100-939 likes. Memory is it's favorite Patriot 2X512 "XBLK":

    Here's what I'm getting:
    BIOS: Cu51M127 Mod
    Vcore: 1.65V
    Vdimm: 2.9V
    Memory: 2X512Meg
    Mem Timings: 200-2T-2.5-4-3-8
    HTT Ratio: 3X
    CPU Ratio: 9X

    FX55 0442 "CA": Max boot: 230Mhz Unstable

    Winchester 3000 CBBID 0503 : Max boot: 230Mhz

    Winchester 3000 CBBID 0451 EPMW: Max boot: 250Mhz

    SanDiego 3700 KABGE 0529 APMW: Max boot: 260Mhz

    Winchester 3200 CBBFD 0433 SPMW: Max boot: 280Mhz

    Opteron 148 CAB2E 0543 FPAW: Max boot: 280Mhz

    Opteron 148 CAB2E 0545 CPAW: Max boot: 280Mhz

    Venice 3200 CBBLE 0513 DPBW: Max boot: 290Mhz

    Opteron 144 CAB2E 0602 GPAW: Max boot: 320Mhz


    The above results are independent of memory settings or BIOS version. Hopfully this means there is still hope for a fixed BIOS....

    Re: TForce6100-939 - The Ultimate Info Thread

    Biostar 6100-939 Final Analysis

    Here's what I conclude so far:

    1) The board prefers Patriot "XBLK" over G.Skill "LE". G.Skill "GH" UTT(BH-5) got to 240 @ 200 1T 2-2-2-5 thanks to the 3.3Vdimm jumper option.(All mem 2X512)

    2) The board prefers:
    A) FX55 0442 "CA": 230HTT Unstable
    B) Winchester 3000 CBBID 0503 CPU: 230HTT Max
    C) SanDiego 3700 KABGE 0529 APMW: 260HTT Max
    D) Opteron 148 CABYE 0543 FPMW: 280HTT Max
    E) Winchester 3200 CBBFD 0443: 290HTT Max
    F) Venice 3200 CBBLE 0513 DPBW: 290HTT Max
    D) Opteron 144 CABYE 0602 GPMW: 320HTT Max

    3) Best BIOS for overclocking is the CU51MA12 BETA available on The Rebels Haven TForce 6100-939 BIOS Page. I have tested all the BIOS on the BIOS Page as of this posting, with the exception of the 6100-M9, which I believe to be compatiable with the 6100-939.

    Conclusion:
    The is another low priced board that is overclock crippled due to crippled BIOS's. It is still a good choice for the budget minded user as the onboard video is a real plus. Also it's mATX size makes it nice for a smaller case eating up less room. For $70US or so, it's a nice tinker board for those with "tinker" funds...


    As I play with this board more and more, I have to say that it's a nice stable board. If coupled with a CPU that has an 11X multiplier or higher, all sorts of possibilities open up...

    The Vcore max of 1.7V and the 3.3Vdimm are options only found on boards twice the price...

    And with any luck at all, a BIOS will be released that allows 300+ FSB with all CPU's.....

    Anyone wanting a low priced winner, the Biostar 6100-939 is certainly a candidate...

    Biostar Tforce 6100-939 Chipset Vmod

    In an effort to be able to boot at an HTT of higher then 260Mhz, one of the things I looked at was the Chipset Voltage level. Measuring 1.18V on my board, I decided to increase it by about 0.1V to see if at least I can boot a little higher. While it didn't seem to help at all, here is the Vmod for anyone that wants to experiment.

    That said:
    If you do this or any of our mods, your doing them at your own risk. The Rebels Haven Computer Forum will not be responsible for damaged systems or components... If your unsure about the mods, I strongly suggest you do not implement them...

    The PWM chip is a 8 Pin RT9214 and here is the schematic of a typical circuit and the pinout of the chip:



    The Mod involves connecting a 1K resistor from Pin 6, the FB Pin, to Pin 3, the Ground Pin. The mod should look like this, as it's too hard to solder right on the IC Pins. Connect the left hand side of the resistor to the left hand leg of the FET(drain). Connect the right hand side of the resistor to the left hand side of the chip resistor as shown. Tips on soldering are here. And, while I didn't solder it in, I connected it in a temporary manner to do the test. The Chipset Voltage with the Mod installed, measured 1.26V:

    BIOSTAR TForce 6100-939 Tips, Bugs and Workarounds

    3.3Vdimm Jumper

    Displaying a unbelievable amount of foresight, Biostar chose to include a jumper that feeds 3.3V directly to the Vdimm bus. Be aware the the Bios Vdimm control no longer works when this jumper is set to the 3.3V position....

    Anytime a Memory Module is fed this high a Vdimm, provision should be made for a seperate fan blowing directly on the Modules...


    Which Memory Slots to Use?

    As usual the manual isn't very clear, at least for me, as to which memory slots are going to give the user the "Dual Channel" mode.

    The same color slots are "Dual Channel". This would be 1/3 and/or 2/4 numbering starting from the CPU..

    North Bridge Needs A Fan...

    Even running default settings, the North Bridge is very warm to the touch. I have mine setup out of the case and it's very warm. I would think that when the board is enclosed in a case, where the CPU is air cooled, the temp of this component may even cause instability....


    Which BIOS To Use For Overclocking

    Having tested the available BIOS's, here's what I see running a 3700 San Diego:

    CU51M920 9/20/05
    Only 4 main memory settings and CPC; no POST at 245

    CU51MA12 10/12/05
    Only 4 main memory settings and CPC; POSTs at 265

    CU51MA20 10/20/05
    12 memory settings and CPC; POSTs at 260.

    CU51MB02 11/02/05
    12 Memory settings, Vcore goes to 1.8V in BIOS, but measures 1.55V. 260 max POST.

    CU51MC02 12/02/05
    Support for FX60 and nothing else is obvious.

    Actual Vcore and Vdimm readings

    I measured Vcore and Vdimm using a Digital Multi-Meter. Here's what I got:

    Biostar 6100-939
    CU51MA12 Beta Bios
    Winchester CBBFD 3200

    Vcore:
    1.40 = 1.397V
    1.425 = 1.422V
    1.45 = 1.446V
    1.475 = 1.472V
    1.50 = 1.496V
    1.525 = 1.521V
    1.55 = 1.546V
    1.60 = 1.614V
    1.65 = 1.655V
    1.70 = 1.722V


    Vdimm:
    2.6V = 2.64V
    2.7V = 2.73V
    2.8V = 2.84V
    2.9V = 2.93V

    3.3V = 3.33V (This value is PSU dependent)

    Overclock Settings
    Here are the important settings to start overclocking the Biostar 6100-939. Set the following in the BIOS:

    Advance Chipset Features:

    Biostar TForce 6100-939 BIOS Screen Shots - Part II

    The PC Health Status. I like to set the shutdown to 60C:


    The main screen of "The OverClock Navigator Engine" everything the serious overclocker could want in 1 place:


    Setting "The OverClock Navigator Engine" to "Automate Overclock" allows 3-4 different degrees of overclock to be set by the BIOS. I tried a few of them, and 1 froze the system, so they are not just 5% or 10% increases. Biostar did a real nice job on this board, but the BIOS mem settings need some tweaking:


    Setting "The OverClock Navigator Engine" to "Manual" allows the serious overclocker complete comtrol over critical settings:


    Opening up the "DRAM Configuration" window, we find a fairly ample amount of memory settings. Early BIOS only had a few of the basic settings. But, there are at least 5 more that should be added to these 14:


    And finally, "The CMOS Reload" window, for saving your fav bunch of settings:

    Flash T-Force 6100 939 Bios With USB KEY

    Disclaimer: Flash at your own risk.

    I found this at [H] forum, quite informative:

    http://www.hardforum.com/showthread....post1029079862

    Courtesy watson1987 at [H] Forum:

    quote:
    --------------------------------------------------------------------------------
    Flashing your Biostar T-Force 6100 939 Motherboard without a floppy drive involved booting off a USB key, that has the flashing program and your newest bios image

    Thing to Download

    http://h18007.www1.hp.com/support/f...load/20306.html

    Press Download

    http://www.datoptic.com/Drivers/DAT.exe

    Should start the download (I'm not sure if I should be hotlinkin the download like this) I have tested my usb key only with this DOS image, Im sure others will work, but I have not tested them

    http://www.biostar.com.tw/t-series/...etails.php?id=3

    This seems to be the latest bios, however the American Biostar website has another version as their latest, currently I used the American site for lack of knowledge for the correct bios

    http://www.biostar-usa.com/mbdownlo...tforce+6100-939

    Download AWARDFLASH_826G_DOS.EXE

    What to do now?

    1. Stick a floppy into your host computer (or use a virtual floppy program like the one found here - http://chitchat.at.infoseek.co.jp/vmware/vfd.html)

    2. Run the DAT.exe file, and press "Create", this will create a bootable floppy disk image which you will use for your usb key

    3. Run SP27213.exe file, which you downloaded from the HP website, go through the installation press next and accepting everything

    4. Run the new shortcut found on your desktop called HP USB Disk Storage Format Tool (don't worry it is not just for HP usb keys)

    5. Select your USB key from the drop down menu, select "FAT" filesystem, check "Quick Format" and "Create a DOS Startup Disk". Now press Browse and find your A:\ drive, and press OK.

    6. Press Start and wait a couple seconds (say 20 seconds) and it should be done

    7. Take the downloaded image and AWARDFLASH_826G_DOS.EXE and extract the contents by running the program (you should have AWD826g.exe, and README.TXT), first rename the AWD826g.EXE to something like flash.exe as this will be easier to work with in DOS (you can delete or read the text file). Take your image (whether it be *.bst, *.rom etc..) and rename it to image.bst or whatever the extension was before you renamed

    8. Copy these 2 files (the image and the flash.exe) onto your usb thumb drive via My Computer, I opted to create a folder called bios (eg J:\Bios\ *put files here* )

    9. Restart your computer, press F9 at the bios load screen and select your USB key from removable hard drives, it should come up as a USB Harddrive (atleast mine did)

    10. Since I did not have a hard drive installed I got the DOS prompt at C:\ (this make be different then you) To double check type "dir" without the quotes and press enter, you should see a folder called "Bios" or your other image files if you didn't make a folder. If you made a Bios folder type "cd\bios" and press enter

    11. Now type "flash.exe image.bst" and press enter, follow the onscreen instructions by press "Y" and typing in a file name for your OLD bios if you want to save it, let it to it's thing and you should be done

    Flashing Your Biostar TForce6100-939 With WinFlash

    UncleBob in the Chaintech Forum has probably made the best HOWTO for WinFlash HERE

    Not much at all can be done to improve upon it...Great Job UncleBob

    Biostar has their own version of winflash...T-Utility BIOS Live Update...comes with the board, it does work very good as well.
