Duron Multipliers

I'm about to put a 1300 Duron on an ECS K7S5A in my livingroom PC. I liked running my old Duron at 133 FSB so I could get all of the memory bandwidth I could, but the K7S5A doesn't have multiplier control so I could drop down the multi to correspond with the FSB.

Is there a way you can short (pencil trick - gotta love ceramic packaging) certain bridges to choose a certain multiplier on the Morgan core Durons? Ideally I'd like a 9.5 or 10x multiplier. It's going to be in a small case and I don't want to OC it much and make it hotter. Just want the full 133 fsb :)

    good question...

    I have 2 durons, a 650 and 1000 im running the 1000 right now... running it at 133 would be most excellent..

    It's quite nice actually. On my KT266a board, I ran my Duron 1Ghz at 133x8=1066. Not that much faster than stock in CPU Mhz, but the 133 FSB and the Morgan core made it better than a Thunderbird core Athlon 1Ghz.

    I found a multiplier mod for the K7S5A, but I'd rather not do any soldering. If there was only a way to pencil in some bridges on the CPU...

    After staring at this for about 20 minutes I finally figured out how the multiplier is chosen from the bridges.

    My Duron is Palamino derived, so look at the Palamino picture. The one they show happens to have the same multi as my Duron, and thus, the same bridges connected.

    Currently, 13x

    L3= ||::
    L4= :||:
    L10= :|

    I want 10x, which I believe would be:

    L3= |::|
    L4= ::||
    L10= |:

    So... how would I go about disconnecting the 3 bridges that are connected now that I don't want connected any more? The easiest, quickest way possible is what I need since I was planning on building this tonight. I might just build it at stock multi and pull out the CPU later, though.

    And can someone check my logic on the bridges and see if I've got it right?

    You guys are the greatest :D

    To disconnect them, you can use a sharp knife, and cut the bridge.

    Here's a useful site:

    Enjoy. 9.5x multi.

    L10 is the flag introduced to allow multipliers above 12.5x. When it's set to Open/close ( l10> : | ), it's 13x+. Close/open ( l10> | : ) it's 12.5x or lower.

    I'm a little confused about the L6 bridge Thrax. On mine, it's on the bottom side of the chip (with writing on the core right-side up) with the L5, 7,8, and 11 bridges.

    And L6 currently looks like .|||||

    And it wasn't on the pictures on the site that shwaip or I posted. :scratch:

    So, let's say that I accidentally have both the low and the high bridge connected because I couldn't sever the bridges enough. Are we talking no post or are we talking fried stuff?

    (cutting bridges now)

    Well... I was ineffectual. It starts up with the default 13x multiplier. Eh, it was worth a try.

    Thanks for the help though guys.

    try running 133x13, you never know. i had a 1.0 morgan that i ran at 10x133 w/ no problems. default voltages.

    Really? Well I'll give it a shot then. It turns out I'm going to have to put this system in a bigger case with more airflow anyway.
    My old Duron 1Ghz would only make it to 1200, but it was one of the very first ones made.

    Dang- forgot to write down the stepping on the new one. :doh:

    yeah, it's a stretch that it'll do it. i figured since at the time, don't know about now, the morgan cores went to 1.3 they may just be rebadging them, so i tried it.
    anyways, the core on it was DHLCA, or some combination of those, i just remember it was a D up front, cause alot of people had an A and i kept thinking i read it wrong.

    My old Duron 1.0 was a AHHAA, but this one is a D something.

    Unfortunately it didn't like 133x13 :(. Would have been nice to have the only Duron 2100+ on the block :).

    I'll put the modded BIOS on and maybe it'll take 110 or 120.

    Duron 1gig processor: 30$
    Athlon 1.3gig processor: 40$

    Gargoyles fear as he cuts the bridges cuz he is as cheap as me: Priceless
