o/c duron and voltage ?'s

[juliendogg]

howdy, i just picked up a duron 1000 to hold me over since i somehow killed my xp. i know this chip isn't gonna be a great oc'er but i was wondering how sensitive to voltage they are. is it worth putting the volt-mod back on my shuttle or do you need more than 1.85 for a duron. i'm watercooled so the higher voltages shouldn't be a real problem. my temps are around 32-34 under load.

i had noticed with my xp that it did better with voltages up to 1.95 but any higher didn't really help much. i never got the chance to try it with my watercooled rig though.

morning...

well I have a duron 950 that I used to OC up to about 1050 or so, never got over 1100. This could have been a cooling/heat related issue though.

I believe that my 950 was in a block where basically the 600's-950 are pretty much the same chip. With your 1ghz, you are starting at the bottom again and I think the 1g-1.3g are the same chip.

I guess I am saying that durons can handle the voltage, so if I had a volt mod I would push that lil-sucker up to at least 1200 :-} Maybe +.125v over the default for the chip. Especially if I had water cooling!

But that's just me. Let us know how you fair with it.

Duron 1000MHz CPUs are the first of the 'Morgan' chips - their limit is around 1300 to 1400MHz.

Try increasing voltage as necessary until the chip is stable. If you can get to 1300Mhz but not much further, then there is little chance that increasing volatges any further will help - the Morgan core has its limits.

Try increasing voltage, be careful of temps.
Take the voltage small steps at a time.

well. a little over 1200 seems to be my limit now. kinda dissapointing after my 300 mhz o/c on my 1700 with air cooling. i kinda slacked off on trying cuz i got tired of clearing cmos.
even had some data corruption trying to get to 166 fsb. guess that's hard drive issue.

right now i'm 150x8 (chips unlocked)

Have you tried adjusting PCI dividers?
At 166MHz FSB, try a 1/5 divider if possible. 2/5 for AGP.

 

[juliendogg]

the shuttle doesn't have selectable dividers...

actually. i've done a format and reinstall and can't seem to get my fsb up above 144. used to run good at 150 ran it at 166 with my xp.

i'm thinking the duron can't handle the higher fsb's without creating mad errors.

voltage is at 1.85, didn't replace the volt mod yet and don't think i will with this chip. i'm more interested in fsb than chip o/c anyway. i'd like to get back to at least 150.

The XP started at a 133 FSB anyway, so 166 is a small boost (33MHz) compared to a 66MHz increase for a duron.

On an XP you increased the bus by 25%. On a duron this is 66%.

 

[juliendogg]

so has anyone been able to run a 100 mhz fsb chip at 166? specifically a duron? if you keep clock speed near default or maybe even underclocked by multi can you get bus speeds that high?

i know the weakness has to be the chip cuz my system ran 166 with the xp.

more voltage?

First, a 1 gig Duron may have either a Morgan or a Spitfire core. Do you know which this is?

Second, I'd put the voltmod back on. I've got a 750 that couldn't even boot past 950 at 1.85. With the volt mod I cruise easily at a gig. I can actually run it at 1100, but I have to turn up my fans to get a temp I'm comfortable with and I don't like the noise. I haven't really played with super high fsb on this rig. I keep it around 133 so that everything else is happy.

here is my experience.

i have a duron 900 that can go up to about 1090 or so thus far in win xp. when i was running win2000 i could set it at 133x9 no problem. i had even gotten it up to 1240, voltage was about 1.80 or 1.825 i believe. watercooling. for some reason it won't boot winxp at 133x9. anyone else notice this? i was just starting to like xp again too. it does seem a lot slower at 1000 than 1200.

haven't tried using my voltage mod again on it though.

i'm really more interested in higher fsb than clock speed. that's where the performance is. i have mostly high quality components and they've all checked out ok at 166 except the ocasional hdd problem (which i'm also trying to figure out how to fix, not getting far with it while i'm stuck at 144 though) i'll likely be selling this chip soon some i'm reluctant to volt-mod it. but if it worked well and i got some high clock spd's and fsb i'd prolly keep it until i can be equiped with a t-bred.


not sure what the load temps gonna be yet. i've done some work on my bong today and so far i'm running 28, been crunching seti for an hour and surfing... gonna do a burn in tonight and see what temp it gets to. maybe help my o/c tomorrow too... who knows?

thanx for the input. i'm gonna start a new thread requesting high fsb's on durons.

HAPPY OC'ING!!!

oh yeah.. and keep it COOL!

no, i don't know. i was asking in the begining of the thread how to tell. sales add doesn't specify.

 

[weasel]

i dont know about the morgans but i found out that the spitfires couldn't take the volt mod, i killed my 750 with 2.03v(less than 24 hours)

I've just started really playing around with my 1G DURON, and contrary to what some others are saying, my experience with the DUORNs, both the Spitfire and the Morgan, is that they will run quite well at a high FSB.

I've had DURON 600's to over 1100MHz with the FSB [email protected] on boards with the KT133A chipset as well as an FIC AD11 with the AMD 760 chipset.

AS I sit here, this machine is running happily with a Morgan core DURON [email protected] with a 201MHz FSB. This is on an Epox 8KHA+ board with the KT266A chipset (BIOS v 8kal00) that utilizes a 3/4-memory divisor bringing the memory bus down to 151MHz. The CPU multiplier had to be lowered to 6X to achieve this.

My CPU temperature is in the mid 50's as reported by Sandra. I would like to get this down, but I have this machine under a desk in the knee-hole sharing the space with two other machines, all overclocked. (some re-modeling is going to be done around here when the weather breaks!)

My experience has also shown that the Morgans, like the XP's, don't seem to benefit from too much voltage. Some increase is still needed to get stability, but not the extremes that the T-BIRDs and Spitfires required. I'm running at the boards max of 1.85v with the memory voltage increased by 0.30v.

This machine is currently under 100% CPU load running SETI in the background.


I'll post the benches if you like.

I hope this helps.

Good Luck!

nice, thanx for the tip
