Spitfire versus Morgan

[SteveI]

I am thinking about getting a Morgan. Since most etailers won't tell us, where do spitfires stop and morgans begin. I think there are 1.0gig versions of both, higher is always Morgan, lower is always spitfire.

Will someone confirm this for me?

TIA
SteveI.

Here's a list describing the various Duron's that exist.

Duron 600 - 600MHz (100x6.0) - 1.5v or 1.6v - 64KB L2 (Spitfire)
Duron 650 - 650MHz (100x6.5) - 1.5v or 1.6v - 64KB L2 (Spitfire)
Duron 700 - 700MHz (100x7.0) - 1.5v or 1.6v - 64KB L2 (Spitfire)
Duron 750 - 750MHz (100x7.5) - 1.6v - 64KB L2 (Spitfire)
Duron 800 - 800MHz (100x8.0) - 1.6v - 64KB L2 (Spitfire)
Duron 850 - 850MHz (100x8.5) - 1.6v - 64KB L2 (Spitfire)
Duron 900 - 900MHz (100x9.0) - 1.6v - 64KB L2 (Spitfire)
Duron 950 - 950MHz (100x9.5) - 1.6v - 64KB L2 (Spitfire)


Duron 1.0G - 1000MHz (100x10.0) - 1.75v - 64KB L2 (Morgan)
Duron 1.1G - 1100MHz (100x11.0) - 1.75v - 64KB L2 (Morgan)
Duron 1.2G - 1200MHz (100x12.0) - 1.75v - 64KB L2 (Morgan)
Duron 1.3G - 1300MHz (100x13.0) - 1.75v - 64KB L2 (Morgan)

Physically, the core on the Morgans are rotated 90 degrees from the Spitfires.

Shweeet!!
I guess I can assume that all 1gig Durons are Morgan cored. Looking better and better.

I've been told that 1gigers exist in both formats. The sourses who've told me are sources I trust but I don't know personally. Even if there are both, you'd probably get a Morgan if you ordered one now unless the company you buy from has older stock laying around.

A look at two of AMD's Duron handbooks is a bit confusing. Rather than listing that a 1 Ghz Duron might be Spitfire-cored(and thus a Model 3 processor) the info is that a 900 Mhz and 950 Mhz Duron might be Morgan-cored, Model 7 CPU.

Looks like 1 Ghz Duron must be a Model 7, ergo Morgan-cored processor. BUT, some 900 Mhz and 950 Mhz Durons might be Morgan-cored as well.

I dunno. Conventional wisdom seems to be that "there is a chance that you could get your hands on a 1 Ghz Duron that has the older Spitfire Core, aka Model 3 processor." And into folk tales we go, again.

[whatever]

SteveI, how far are you planning to oc the morgan Duron once you get it? Morgan Durons oc okay I think.. Mine now maxes out at 1.287ghz with stability. 1.3 with unstability. So, I up the FSB to the limit, hehe.. I'm now at 208mhz FSB.

I guess as far as it is willing to go without a fight... OK, I'm lazy, I'll take what comes easy... I will have a few socket A systems going, and haven't identified which CPU will go with which mobo just yet. My main rig will go to another desk, so before I set it up, I want to know what the "easy" limit of the CPU is.. For the 2 systems in question I'm thinking, 1 will be XP1600@?? on an Epox 8KHA+, and the other a Duron1gig@?? on the ECS K7S5A. I guess we'll see.

[SiGmA_X]

How hard is it to unlock a Duron? I have my XP1900+ unlocked, but since the core cracked I can't OC it very far.

If you can unlock it, can't you raise the multiplyer and have a lower FSB?

You just need to pencil in the L1 bridges. It's pretty easy compared to the XP since there are no laser cuts between the bridges connected to ground.

There are a couple of reasons you would want to do this. The number one reason I think would be so your other devices run at spec. If you have devices that are sensitive to PCI bus speeds, and you don't need memory bandwidth, then you may as well raise the multiplier. Another reason would be if you have CAS3 PC100 RAM that can't can't run stable above 110FSB. Again, you may as well drop the FSB and raise the multiplier.

Yes but my interpertation at the time took the statement to mean lowering the fsb below stock just to up the multiple, which is pointless. Ie: going from 100mhz X 8.0 to 90mhz X 10.0 just to get 900mhz.

yeah those XP's are a ***** to overclock but u can fill the laser cut chanles with a non conductive meatl and then u can use the pencile to go over it...

[The Spyder]

How could you do that? If you used a non conductive grease it would not work to put a pencil over it- the lead would not stick-

FYI..
I got the 1gig Duron this week from Newegg. It is a Morgan core, and I didn't bother to unlock it. It is on my ECS mobo doing 1.33 at stock voltage, piece of cake.... after a while, I might try 138 fsb, just for kicks. The SDRAM I scrounged up probably won't do much better anyway.

[ral]

Yup, we had the same experience with the Duron's we got recently.

Last year got 4 1.1''s. Tried overclocking two and they both stop somewhere in the 1200++ MHz area at default.

A month or so back I got a Duron 1.0 and is does 1430MHZ (158x9) at 0.1v below default. A friend (Dino) on mine go another one a week later an he is getting 1390MHz @ 1.65v (139x10). Last was Isouljah, he go one a week ago and is running it @ 1400MHz @ 1.7v (200x7).

Looks like the newer Duron's have better cores.

[YviE]

I used to have a Duron 950 (Spitfire) that would do 1200MHz at 1.75v (6 x 200MHz). With the high FSB the little duron performed pretty well.
