Can you enable multis <13 on Duron 1300?

[Octoman]

Is it possible to unlock and enable the multipliers under 13 for the Duron 1300?

[repo man11]

Yes, use the pencil trick and go to it.

[Deliximus]

actually, it's not as easy as we think....the 13x and up on the athlon/duron invovles something with the L3
try connnecting all the L3 bridges

[The Coolest]

As said above its not as easy as connecting all the L1s... Check the Unlocking the 2200+ thread. you have to shirt some pin on the proc to the GND and that way you get 12.5 and lower multies

The Duron 1300 is supposed to be a 5 bit Multiplier cpu, but not sure if it has 4 L3s, 4 L4s, and 2 L10s...or...just 5 L3s.

We'd just try closing the 5 L1s and see if it boots and you have bios control of the Multiplier. If not then treat the cpu as a 2100 if it has L3/L4/L10s or treat it as a 2200 if it has the 5 L3s...treating it means applying the mod that has been found appropriate for the 21000 or 2200...their Multiplier bridges are different as described, so the mods to their (L10 pair or 5th L3) bridges are different.

I haven't been keeping up on my Durons. Not much info out there about unlocking these, but this thread covers it pretty well (http://forum.oc-forums.com/vb/showthread.php?s=&threadid=94108&highlight=unlocking+duron+1300) .

I have done the inverse operation to get my Morgan 1200 to 1300
You have to play with L10 which will then give a different meaning to L3 and L4 (8x less)

If you want to control the mulitplier, you have to do the L1 bridges too


I did my mod using regular pencil (and a DREMEL to obliterate those tiny bridges)

I alos upped the voltage to 1.85 put doing the remaining middle L7

In case you ask, yes I try 14x, but it seems to require even more voltage than my Asus A 7V 1.02 can provide.

best luck with cutting the bridge

Howdy, got a quick question for surmizing or maybe someone has actually done this.


I've been reading about how to unlock the Duron 1300 and I've been told that this Duron chip relates very much to the Athlon XP2100. In this sense you need to connect the level 1 bridges as well as creating a conductive trace between two pins on the bottom of the chip. Supposedly this enables multpliers less than 13. THis comes in handy with a Duron since you can then increase the FSB and use a lower multiplier to get a higher frequency. Really nice benefits all around. My questions are this:

1) Has any ACTUALLY modified their Duron 1300 in this manner and has it worked successfully?

2) Do you suppose it would be possible to create a pencil trace between the two pins on the bottom rather than using a conductive pen or piece of wire? Would this create a situation wherein the impedence of the graphite would not be enough to handle the grounding of the pin? (voltage breakdown)

thanks.

The 2 pins trick IMHO is equivalent to shorting the L10 bridges which is need to access multi below 12.5

see the post form The Coolest at

Be aware that it seems that the max speed for Morgan could be around 1450 Mhz. Getting it require a lot of V, going beyond is for a few "blessed" chips with good MB, good RAM and good cooling.

[axh174]

Yeah, I've been told that the Pin shorting is equivalent to The L10 mod. The thing is I'm wary of Permanent Bridge modding like that. It's why I've been wondering if it may be possible to use a pencil trace on the pins, but before I even try that I'd like to know if someone HAS done the pin shorting and been successful.

I ask because I did try it on my Duron 1300 and the thing went dead, but I'm not so sure it was me because it was kinda screwy at stock speed which tells me I may have received a defective chip.

[The Coolest]

Many people succeeded w/ the pin mod, but I don't think they used a pencil, all have used a wire, which isn't permenant, and this mod WORKS, many people managed to get their chips unlocked by connecting the L1s and shorting the x8 bit pin.

Here is a good article that shows dip switch modifications to an ECS K7S5A, the same could be done with other main boards as long as you have the technical skill and knowledge to do so. Manually over riding bios settings the old dip switch way!
