Aight well you know me and my Duron history. I got my 650 to a gig easily, aircooled with some P.O.S. HSF. Basically, they can all reach a gig if properly cooled (I've had a 650,700,750,800,850). Not much more than a gig at all out of any of them. Also, since the AKCA core is newer, it should be better to OC, but from my experience, the AKBA is better. Basically, find the cheapest Duron you can find and clock it to a gig. 1100 may be attainable with better cooling (SK6 or similar) but I am not positive...that's the upwards spectrum. The Spitfire core fell short of 1ghz officially (950mhz) and 1000-1100 was the limit for this core. The Morgan core isn't fairing any better as it tops out at no more than 1.3ghz.
I'm actually considering throwing a Duron system together just for the hell of it, but I don't know. Money is tight, I think upgrading this system a bit is a higher priority right now.
I second DuronClocker in the ability of spitfires to clock. I had D600, 750 and 800, and none could go over 1000 on my board without voltage mod. Wel, ok ok my 800 went up to to 1100, but my raid was hanging at anything higher than 33MHz PCI bus, so i gave up clocking it any further. Or maybe it was my memory? hell knows. Get the cheapest Duron Spitfire (600 is my best guess) and you will prolly get the most out of it, topping 950-1000, @1.85-1.9V.
g'luck bro, I am up for upgrade to a TB 1.4, will dump my duron and my gf2mx to my sis in a new pc. Though they did their job for a while.

my new favorites are the 1000 and the 1200 which will not OC as much, but nevertheless are the best duron's ever made.
LoL! They better be...they can outclock the Spitfire by 200-300mhz and have SSE and data prefetch!
Also, I wanted to mention, get one made between week 24 and 38. The 34-38 seemed to do the best, but the others did fairly good too. Anything else than those for the Spitfires, and there is no point in trying to OC

1Ghz? ... Well I have a 650Duron with a Gigabyte 7ZM motherboard. I can only overclock the FSB, which will in turn, produce a little bit higher in CPU speed.
With a crap OEM fan ... Using EasyTune, I'm only overclocked at 670Mhz
I know DuronClocker is laughing right now,
But the lesson is make sure your motherboard has good overclock capabilities to squeeze the most of your system.
Silence - Have you tried closing your L1 bridges and your L7 bridges, then setting your FSB speed to 133? That would give you 1.85v default in your mobo from the closed L7's, and you should be able to set your FSB speed to 133 with the L1's closed giving you 865mhz. Unless there is no way to set things to 133FSB on your mobo.....
The above is what I did with my ECS mobo since the multipliers are locked. My 700 easily is running 933mhz on the ECS K7S5A using the default 7x multi, 133 FSB speed, and the 1.85v L7 trick!
yes, to get multiplier control, you need to close the L1 Bridges. If your board supports no multiplier adjustments,and you want to up the multipler, you'll have to set em manually on L4 and L6, some boards just need L6 to be modified for voltage change while other are less tolerant and need both bridges changed. you are sure to get 866Mhz out of that, but you'll need more man! so i say up the multiplier to 7X or 7.5x for 933 or 1GHz. You may not need to modify L7 for a boot at 866Mhz, i have never really needed to do that except for a duron 900 and 1000Mhz where the chips could not handle 1200Mhz and 1333Mhz even for a brief moment to boot.
Yes, you would need to modify your L1's to what multiplier you want, and I suggest 7x to start. As Justintime said, go for 933 (7x*133) as your Duron should go there easy. I would mod the L7's for 1.85v anyways. It won't hurt it and will help with stability. Use a good heatsink though....
