To use JumperFree Mode or not on a Asus A7V-133

Howdy all,

This will be my first attempt at updating an older system, but I've got a discrepency in my settings according to the manual. It has to do with the JumperFree Mode on an Asus A7V-133 rev. 1.04 mobo and the overclocked 700 Mhz Duron.

I just bought this from a guy to learn on, so please be patient at least for a while :)

Can the motherboard operate if the settings have a combination of Jumper Mode and JumperFree Mode?

I have a link to the manual and page numbers if that willl help in any way.

Right now I don't know if I should get a cup of coffee or another beer

Cherrio,

Polock

    Hi Polock

    I too have an old azv-133.
    the jumper-free jumper disables all the other jumpers. You then set all settings through bios. which I would suggest. It is a lot easier than phisicaly moving all those jumpers when trying to figure out what works. If you like the idea of it being done Static, then after you figure your optimal settings through bios settings then make your final settings with the jumpers and take it out of jumper free mode.

    Hope that helps

    Scott

    Disclaimer: I too, am rather new at this so if some one wants to correct me feel free.

    Thanks Scott...I'm really looking forward to learning a little with this project (my daughter is too :) ).

    I think it's the JEN setting that has me baffled. To explain more clearly, here's a link to the A7V-133 manual for easy reference with my description. Sorry if I don't explain very well...I'll get there :respect:

    Here's what I have:

    The Dip Switches-DSW are all set to on (100 Mhz setting as shown in #7 on page 22).

    The VID settings are all jumpered 3-4 (CPU Default/JumperFree{Defaul} in #9 on page 24).

    The JEN setting is jumpered 2-3.

    The Bus Frequency Multiplier is set to 9.0x (Page 23 under Important it says JEN should be set to 1-2 to use this).


    What has me baffled is the diagram on the bottom of page 18. My settings indicate a little of both worlds. Is this possible? It works, but should it?

    Cherrio,

    Polock


    Dern it...can't get the link to work in the post, but it works in a separate IE window. I'll keep trying. That's why--the Asus site is down for repair.

    Look at 2. in the attached screenshot

    it is also on page 22

    the jumperfree mode will disable all the other jumpers. and all of those options are available through BIOS.

    The jumpers on my board are also at the 100 settings but using the Bios it is running at 133

    JEN means Jumper ENable.

    1-2 is ON.
    2-3 is OFF.

    Polock has his Jumper-only disabled, and Jumpers ENabled will override BIOS selections, as the hard settings done with jumpers for base things are detected and loaded first.

    When you disable the jumpers Enabled, you are essentially telling the BIOS to control-- the soft settings totally rule over the hard jumpered settings. When you tell it to use hard jumpers, you are making circuits that the BIOS sets itself to by detecting the jumper settings.

    BIOS selections are like soft switches(on or off, binary 1 is on), hard (jumpered) switches (actually routing through circuit options) actually force BIOS to confom to jumpers. The JEN allows you simply to choose to use soft switches or not for the switches for which the JEN switch controls the use of the jumpers it controls. It is barely possible that the jumper enable circuit does not actually control multiplier of 9, though the book for that mobo says it does.

    Essentially,the 9 multiplier is a BIOS extension,that is why JEN should, by book for mobo,be enabled with jumper set to 1-2 shorted or bridged by conduction through jumper block brass or copper connector inside block. Physical jumpers complete circuits when blocks are present, and leave them open when not jumpered. Short means current is flowing, in re jumpers. This sounds like a contradiction, but BIOSs can internally multiply a jumpered setting by a certain amount over what the jumpers are set for, and I think that is what is going on here.

    Some jumpers, like audio or other things, may be outside what the JEN does, but Polock is using the BIOS. It looks like the rev baord he has has an improved BIOS from the pure V 1.00 board, so the BIOS may be using BIOS setings better than originally planned, or use some settings from BIOS that the original BIOS did not. The circuit may have been modded also, though those details sometimes do not get stuck in docs. I do not have one of those Motherboards, so cannot emperically test for you, but can tell what the JEN does for you.

    Either way, if set right, will work, the soft way, if you see what the BIOS does, is probably easier simply because you can see it. having an older manual than board rev can leave folks confused, and most modern rev is often on the motherboard CD or at a mfr website in Acroibat Reader readable format (.pdf). so if you get a newer manual that says something different and the manual is for your vrsion of board, then the newer is usually more accurate-- not always, but usually. The printed manual is probably the most obsolete in any situation where board rev or BIOS rev is more modern than book.

    I stuck this in for you and for others who might benefit from knowing this.

    John.

    While I spend the day in the snow dodging cars and trucks spinning out of control, you 2 have managed to get into my thick skull. Sometimes I can't see the forest for the trees. Wish I could buy you a cool one :cheers:

    Now that I know what JEN stands for, it is amking more cents. Excellent description of what it is, Ageek.

    Thanks for the hi-lite Scott. By having my JEN jumpered 2-3 was actually diabling the jumper mode. I had assumed, after I figured out the 100 Mhz and 9.0X multiplier was the 900 Mhz, that I was running in jumper mode. Looks can be decieving at times to an ijut :)

    Think I'll plug this system in tomorrow after my daughter heads out to school to see what the Bios has in store. Gotta learn what I got before upgrading to the 1900+ Palamino.

    Guys, I gotta give you 3 thumbs up just for bearing with me. I do appreciate.

    :thumbsup::thumbsup::thumbsup:

    Glad to see you have a handle on it . You will have more questions.....just ask. These guys are great and will get you all straightened out.

    I'll take you up on that brewski anytime.
    I do have one rule about drinking though...I will only drink if I am alone or with someone !

    I wouldn't say I have "a handle on it" as yet. Let's say it's handling me :bigggrin:

    Start the tally sheet...one brew each to Scott and also Ageek :cheers:

    If time permits, I'm going to plug this box in and see what the Bios is saying.

    Cherrio,

    Now this is really startin' to p--- me off. Gotta think out loud here so I can hear myself think :crazy:

    Plugged the system in and it booted into XP Pro without a hitch...that's good. So I re-boot into the BIOS to be greated by a setting of MANUALLY showing under the Operating Frequency setting.

    From this I'm thinking that we are in the Jumper Mode, but how can it be with the JEN set to 2-3 (off)?

    Can I damage anything if I change the setting back to 700 MHZ in JumperFree Mode?

    Easy there big guy....

    Sorry for the late reply.

    If you think about it for a minute...Manual means you have to set them. You are in the Bios when it tells you Manual...so...set them. I just checked my kids machine ( the box with the A7V-133 ) I must have a different rev. or Bios . Hers says "User Defined" The other choice is "Standard" Also when "User defined" is highlighted ...on the right side of the screen it says something to the effect that..you can change clock speed and multiplier if you are operating in "Jumper Free " Mode.
    My guess is that yours is running at the defined jumper settings. But, You can change it in the BIOS. Try it. At worst you my have to clear the CMOS and start over.

    I hope that helps

    Check page 60-61 of the manual you linked to above.

    Howdy Scott...

    I'm worse than your own kids, aren't I. Really do appreciate you hangin' with me on this. I think your right about the BIOS versions...mine is v1009 and the mobo itself has Rev 104 stenciled on it. I've always been a written documents type of individual. In fact I have pages 60 & 61 memorized :D

    These are the facts as we know them:

    My board is operating in Jumper Free Mode cause I went into the BIOS, changed the CPU Clock Multiplier to 8.5 (down a half), saved and re-booted running at 850 Mhz instead of 900 Mhz.

    Here is the BIOS discrepancies on my BIOS version:
    Operating Frequency Setting = Manually, 900 Mhz or 1200 Mhz are the choices, not User Defined and Standard
    CPU Clock Multiplier = 5X up to 14X
    CPU Frequency = 90 Mhz up to 200 Mhz

    What had me hung up, and still does, is the example at the bottom of page 18...the 5 DWS switches should be OFF, not ON. But just like Ageek had said, when the JEN setting is to Jumper Free, it disables the Jumper settings so maybe the DWS switches are irelavent while it's in Jumper Free Mode.

    I should be able to change all 5 DWS switched to OFF without changing anything if the JEN is jumpered 2-3. Make cents????

    Hanging with Mr. Coo, I mean Scott :D

    I'm sure my daughter will enjoy this system, If I can manage my lack of brain cells (by-product of the 60-70s era :doh:

    I suffered the same problems in the early 70's....Brain cells regenerate don't they ?? ( I am still waiting ! ) Now we can look forward to alzhiemers.

    I looked in my manual and I see what you are talking about, Mine also says the default for DSW in jumper free mode is "all off " . But I guess it does not matter.

    What is the "Stock" rating of your Duron? 700 ? what FSB ? 100 ? 133?

    Next time you have the cover off set the DSW to all off and see if it makes any difference.

    I remember a friend once saying that we needed to destroy some brain cells tonight, so we can get new ones. Last I checked, we're both waiting as well. Our only remembrance was "it must have been fun, why else would we do it".
    Enuf old fart talk...

    I do believe I have a 700 Mhz Duron currently. I already have on the desk a 1900+ Palamino as a replacement, so I was glad to see a newer BIOS (v1009) with a multiplier up to 14X.

    Think my daughter is in the other room engulfed in Calc, so I will switch the PCs around and do some switching...kvm switch sure would be handy 'bout now ;D

    :cheers: I think we have a lift off...

    Flipped those 5 switches to the OFF position and it made no difference within the BIOS. Still had 3 options: Manually, 900 Mhz and 1200 Mhz.
    Changed the multiplier back to 9X and it went back up to 900 Mhz.

    All I can say at this point is "lesson learned".

    When you looked in your case at your A7V-133 mobo, which IDE channel do you have your hardrive connected to?

    Mine was set up with a CD-ROM connected to the Primary Master and the harddrive to the Secondary Master. I always thought it should be the other way as a standard.
    He had the BOOT sequence set at Other BOOT DEVICE -> IDE Hard Drive -> CD-ROM -> Floppy, so I guess that's how he compensated.

    Sorry to ramble on...it's the excitment of gettin' jumpered :)
