duron to athlon

[tomasxp]

Hello, I want to ask one thing. I got AMD Duron 650mhz on my old pc, today I got AMD Athlon 950mhz processor sockets both A. Can I replace my old processor with this one without having any hardware problems?

Welcome to TechIMO!

Wow, I thought I worked with old stuff

Many boards will as I recall, They have the same Front side buss speed 200Mhz

The voltage is higher on the Athlon 1.7 vs 1.6

We would really have to know what board you have, as they are not all the same.

I don't know if it required a BIOS update either, but with a good set of specs, (at least the motherboard brand, and serial number) we can probably figure it out, though.


Those 950 Athlons run hot also, but seems to me the Duron did to.

The athlon should work just fine in it, I even put xp2600's and such in these old boards.

Sometimes they max out the cpu multipliers, but better than nothing.

Socket a/462 is all the same, the only thing limiting a few the motherboards would be the bios and the rated speeds.

Don't forget to add some thermal paste on the cpu die.

Thank you.

I heard also about the front side bus speed but later on this forum I found that it changes only at 1.33 Ghz from 200 to 266 so I think I dont need to wory about it.
And I can't find the info about motherboard brand I checked all the corners.

Look on the motherboard, the Brand and Model is most likely printed on the board, unless this is a Pre-built system, like some thing from Compaq or HP or similar from that era.

But also have to agree on the advice, back then, I had a 800 or 850MHz Duron and went to a 1.3GHz Athlon Thunderbird on the same motherboard.

I had been talked into upgrading to the Duron as an Upgrade from my 450MHz AMD K6/2 at the time, with new board etc, and figured I might go for it, but that week I was talking to the shop, the new 800 or 850MHz Durons had come out and was available, and though I couldn't afford the T-bird, I said HELL YEAH, grabbed the Duron.

less than 6 months later I was upgrading to 1.3GHz T-bird. And even to this day, I still have it, motherboard and all from that system (CPU, Mobo, RAM)

WARNING!!!
Everything I state below is for knowledge and I don't recommend anyone to do this. I've seen cpu's explode and fly right from motherboards.
(yes I've done this many times, and sometimes was curious just how far can go for fun, I am definitely nuts)

Just for the heck of it, you can change the multipliers on the cpu by removing/scratching out i think the L10 and using a pencil to use whatever combination multiplier you want, been a few years since I did this, but got it all written down somewhere. I'm sure is articles online about it.
"overclock amd pencil" should bring good search results.

The reason I write this is you can also turn the duron up by overclocking it or maybe your motherboard doesn't support a multiplier you need.

Pencil trick only works on the duron and athlon, not the xp ones because they need cutting and connecting with windshield repair stuff, I've done this and really not worth the effort.

If cpu cooling is adequate, you can even raise the voltage by penciling the resistor on the motherboard that handles cpu voltage, use a volt meter if gonna attempt this, and don't go over the max voltage for cpu.

Yeah can even do the northbridge voltage the same.

As a note:
I overclocked an xp2600mobile in an asus a7v-133c up to 2700mhz thats just popping it into the board and the multi went to over what the motherboard supported. (was a rare lucky coincidence)

Most these old boards have low multiplier maximums in the bios,dipsets or jumpers. Bios in these old boards was for looking at stuff, not setting anything. Motherboards and bios make all this stuff so easy this day and age.

There was a time when putting together a computer you actually had to have much knowledge and skill to even get them working.

The amds usually run best at a 1 to 1 ratio.

That meaning the duron and other 200mhz cpus run double the memory speeds, in this case would be pc100 sdram memory, the newer were then 266fsb on cpu and using pc133 sdram memory.

There are motherboards that support both or even can mix them up , but the cpu will run at double the memory speed unless the motherboard provides some type of jumper or switch to change this.

The later socket a/462 motherboards had many changes and can pretty much stick anything in them and will work.

One such board would be the incredible abit nf7-s

[stroyal]

I'm only going by an old AMD chart (2003), but the first Athlon on the chart with a 266 FSB is the 1000Mhz.
This chart shows the 950@ 200FSB.
There are 3-1000Mhz, and 2 are 200Mhz FSB, and 1 is 266 Mhz FSB.

The only 1100 Mhz drops back to 200Mhz FSB, for some reason.

By the way, I know it will be hard to believe, but my main board, is still the incredible NF7S rev2.0, with, the incredible Barton 2500Mhz,running for years @ 3000Mhz.

It will do 3200, but I'm conservative.

I miss Abit,RIP.

[ShyguyXPC]

Miss Abit as well, they went down hill in the last years they were around, but before that, they were pretty good.

I still remember a socket 939 (I think it was?) SLI Capable Micro ATX board they made, been trying to find one, but they're hard to find, and when you do, not cheap.

DFI doesn't seem to be doing so well these days either, aside from a couple boards here and there, they seem to be going the way of the dodo also.

Would hate to see them go bye as well.


The Socket A board I've got is an FIC AZ11E, wasn't too bad a board back in its day.

9 Years ago LOL!!!


Also around here I still have a couple T-birds with the Pencil Trick already applied to them, their all 1000MHz or so chips, my stock 1.3 is still faster at stock, though never bothered to OC that thing, I think I had 768MB of RAM on it though, and that was even back in 2002... thats like running 8GB or more today solely for a gaming PC LOL.


Though I never could locate some affordable PC150 SDRAM for the thing back then, some research I had done showed it could support 150MHz SDRAM through Overclocking, but the stuff was so expensive back then I could never afford it, heck I was barely able to afford the PC100/133 I had in the system.

[stroyal]

I think Abit was sold, just before they went down hill.

Asus was one of my favorites, but I lean towards Gigabyte now.

DFI (Diamond Flower Industries) is older than some people know, as they made boards for others, for a long time.

I'm thinning out the old stuff, I'm putting my foot down, and getting rid of everything under 1000Mhz
