Duron on 266Mhz FSB...

[PapaSutra]

Ok, does connecting the L1 bridges on a Duron allow it to go on the 266Mhz FSB? I was under the impression that the L1 bridges only controlled multiplier settings. In other words, what do I have to do to make this Duron take advantage of 133Mhz RAM double pumped?

thanks!

Totally taking a stab in the dark, I would say you need to lower your multiplier in order to use it at 133. At least at first. Then I would overclock the heck out of it.

[PapaSutra]

Well yeah, I know that but...there's nothing else to modify on the chip in order to make it accept a 266Mhz FSB?

Just unlock and crank her up. You will have to watch your multiplier so you don't overclock too far and have to reset CMOS just to boot.
I only had my Duron for two weeks before gettting an AXIA Athlon, but I ran my Duron on a 302MHZ FSB, or 151xDDR=302.

Do the pencil trick and then it will be unlocked, if your mobo allows it then you can up the FSB

I tested a Duron on a KT7A and got 933. On at KT133 board it would make only 900.

Depending on which motherboard you have, you may be able to simply unlock the multiplier via closing the 'L1' bridges, and boot at 133Mhz at a lower multiplier.

If you have a motherboard that has a combination of jumpers and BIOS settings for FSB and multiplier settings ala KK266..you may need to modify the 'L6' bridges in order to change the default multiplier.

This article: http://www.anandtech.com/showdoc.html?i=1440 from Anandtech has all of the lnformation and links, should this step be necessary.

Cool beans, thanks guys. And yeah, the mobo is an IWILL KK266-R.

I currently have a DURON 600 @ 1130MHz (133*8.5), so I can attest that a DURON will go 133. I have to concur with Megahurtz as to his post. I was going to give you that same link, it explains an issue with running some 100MHz chips at 133.

Good Luck!

You haven't stated which Duron you have but you will have to unlock the L7 bridges as well. Connect all those that are cut. I have a Duron 800@1030 (7x147) and 1.725 vcore. You need the 1.85V to post initially then it resets to the BIOS voltage.

Kewl beans! thanks tiger! and nice OC from 1 to 1.5ghz to the other guy! where did you find info on OC V5? And frank can't you double up that duron to 1200. J/K nicest OC of all.

I think I'm at the limit with that chip without the voltage mod, better memory, better cooling. Still, almost a 90% overclock with air cooling and no motherboard mods.

Now with the summer heat on it's way, and the air conditioners going in, I wonder if my wife would miss one of the little 5000btu units that we have?

If I was to install whole house air so I could "legally" (in my wife's eyes), get one of those little window units for a super cooling rig, would that mean that the cooling system on my computer really cost me over $1000.00?

Right now, I am running my Duron 800 @ 800 using a 133 fsb. I have it set to 6x133 and since it stays at 800mhz, I can keep the voltage at default! Pretty sweet!
