Duron 600=>800 stable at 1.5v... How to get that last 100MHz? What are your settings??

[Mac]

Picked up the essential ingredients, an Abit KT7 RAID and a Retail AMD 600 Duron. The L1 "bridges" were broken, so attempted the pencil trick. After drawing and redrawing and redrawing with pencils, I finally went to the local automotive shop and bought a $7 rear window defogger kit...BINGO! The secrets of the universe were unlocked.

The system seems stable at 800MHz at default voltage with the factory supplied fan/heatsink. But, when jumping to 850MHz, all kinds of strange things began to happen. So applied a little voltage that would get a little further but still wasn't stable. However, the heat started to go up dramatically. For example, at 800MHz, running between 100-102F, same as when running 600. But when I made the jump to 850 with a little voltage tweak, jumped to 106-107 immediatlely.

So went heatsink shopping at 2CoolTek and ordered the new GlobalWin. Should arrive by Thursday.

I hear of others running Durons at 900MHz and even some at 950MHz. Curious about what you have done, in particular bios settings, voltage and what temp you are running at. BTW, I am taking my temp measurements from the thermistor mounted underneath the CPU inside the socket.

Thank you for the guidance.

when you jump to 850 and temp rise 106-107 is that under full load or idle? If it's under full load than that's pretty good considering you're using stock HS and Fan. Currently mind is running at 927MHz at 1.75 I think and my temp will sometime go up to 115-120F. What the highest voltage have you gone up to?

107F isn't really anything to worry about, that's only about 41 or 42 celsius. Better heat sink won't hurt for sure, but I'd juice it up until temperatures started running above 50C.

Paldo,

To answer your question, it was just idling. Sort of...went ahead and set the screensaver to kick in and let it run for about a half hour. Never got it to stabilize though even after bumping voltage upto 1.575, however the readout said 1.63 via the hardware monitoring.

Like I said, was just using the factory supplied h/s and knew that if I was really going to abuse it, wanted a more industrial strength cooling solution so backed off waiting for the new cooler to arrive.

Jim Mc,

What voltage are you running?

Thanks,

Mac

Your duron temp. seems OK to me. Don't worry. From 900mhz to 1Ghz My temp rises about 3-5c (or 5.4-9f) for very 50mhz hike and it requires .1 more volt. It reaches 48c idle and is not stable at 1040mhz. Just take a look at my overclocking history as follows:

Speed temp* Vcore X fbs/ram
(mb/cpu) (lowest)
550hz 26/31 1.1(yes) 5.5 100/133 (just tried this for fun and
750 28/35 1.4 7.5 100/133 to see Duron's Vcore limit,
800 28/35 1.4 8.0 100/133 Wow, 1.1 Volt)
850 28/36 1.5 8.5 100/133
900 28/38 1.525 9 100/133
950 28/41 1.65 9.5 100/133
1G 28/46 1.75 10 100/133
43~ (~ after artic silver compound was used)
1030 28/45~ 1.825 10 103/133
1040** 30/48~ 1.85 10 104/133

* cpu idle temp(full load added about 4-5c).
** not stable. failed quake 3 timedemo

My components: Abit KT7, Antac 300w midtower (KS-282, from onvia.com), Viper II AGP, Crucial1 128MB pc133 cl2, Quantum 7200 30G and

****
Retail DURON 600 (wk 29, from Onvia.com too). Use stock fan but add one 6mm old case fan on top of the stock fan (glued on with hot glue gun. Temp dropped about 2C with this case fan. Stock fan rmp jumps from around 5400 to 6400).

Hope this helps

Nomind,

Excellent info. Don't know if mine will jump through the hoops as nimbly as yours but gives me an idea of what is possible and thank you for the bios settings.

Gee, nomind, you've pretty good cooling there. My Duron at 800Mhz gets 49 degrees C at full load and more. With case open however, it gets 46 degrees. Added another intake fan today, didn't do much, merely dropped my MB temp by 2-3 degrees and the CPU by 1 degree. Open casing is still the best! It'll be even better if i point a fan at it.

At 1.07Ghz, i get 58-59 degrees! Had to bump it up 0.05v from 1.75V at 1Ghz to get it to run at 1.07Ghz.

Mac,

I set my bios option at the fastest (turbo ram speed, four way interleaved, fast CPU, shadowed BIOS, Video...).

Oh, I forgot to mention that I let one side of my case opened. Don't remember where I read it, however someone ran his PC fully loaded at the default speed but the highest core voltage for 1-2 weeks. After the torture he was able to clock it up 50mhz higher.

 

[Mac]

Nomind,

Thanks again for the useful information. Rec'd my new heatsink today and finally got it installed (not an easy task) so will start pushing it tonight. Will let all know how it goes. BTW, the GlobalWin heatsink from 2cooltek is a nice piece but the retaining clip is poorly designed. I took it apart and intentionally removed some of the tension by bending with with pliers.

Have been playing with the Duron this morning and think I may have found its limits...or perhaps mine.

I've got it stable at 950 but had to bump the voltage up to 1.775 which reads as 1.875 from the hardware monitoring software. When stressing it (running Q3), the temp would get up to 114F/45C so not too bad. If I pulled the covers off, it would drop another couple of degreesF. At idle, it runs around 106F. From other posts here, doesn't seem that the 45C is dangerous for the Duron.

Tried different FSB settings and seemed to like this the best, 8.5X110=935MHz , at least for Norton. Benchmarked around 245-249...could not get it to hit 250. Made little difference in Q3 though. At 1024X768 with everything pushed to the max, it would do 70fps (use a GeForce GTS - Creative Annihilator 2).

Tried to get it to go up to 1GHz but would crash during boot. It might make it but probably looking at another voltage boost but concerned that 1.9v may fry the CPU. The 1.875v is just barely within my comfort zone. Does anyone have any experience running with 1.9v? Believe that is all I need to hit 1G. Any opinions (knowledgeable, please)?

Mac, I think your Duron has the potential to run over 1 Ghz as long as you crank up the voltage. However, I don't know if 1.85v is OK as a regular setting. I did try 1.85V (shown 1.91v with Via H/W monitor) at 1 Ghz (run stable at 1.775) for several hours running 3dMark 2000 infinite loop in order to crank the speed higher (still failed). The computer looked OK but temp was higher than 50C (forgot the exact number but my room temp was higher). Personally, I would set the speed/voltage at least one rank lower than the maximum. Just my 2 cents.

 

[Racer7201]

I just put my system together Friday. Asus A7V, Duron 600, generic pc100, old viper v330 pci card. Did the pencil trick, using coolermaster fan/hs, running at 105 fsb, 8x for 840, vcore at 1.65. Cpu temp is 50c and m/b is 34c. I'll probably order an FOP32 soon and see if I can't get it higher. I'd like to try the Alpha 6035, but I'm not sure it will work in my case, kinda limited space. Anyone have the total installed height for the Alpha, including the fan?
Thanks,

 

[Mac]

Nomind,

Maybe I wasn't clear. I've manually set the voltage to 1.775v in the bios. However, when I check the voltage with the supplied Via h/w monitoring software, it gives a reading of 1.875v off the mobo. Dunno which is accurate but probably give greater creedence to the monitoring software.

What I'm thinking is that if I boost the bios setting to 1.8v it may finally hit 1GHz but expect the monitoring s/w to show an actual vcore voltage of 1.9v.

Probably wouldn't run it consistently at the higher voltage or speed. After all, after a certain point, the faster CPU doesn't really give any measurable improvement other than higher benchmarks...games are limited by the video card and once you get past around 200MHz, most word processing and spreadsheets are waitin on YOU for the next keystroke.

Racer7201,

I can recommend the performance of the GlobalWin FOP32 but be advised that the installation is a bit trying. The tension of the retaining clip is too great and the heatsink is pretty massive, at least with the Abit because the socket is right on the edge of the mobo next to the powersupply. Let me recommend that you bend some of the tension out of clip and partially remove the power supply to get some working room.

We are all pretty lucky though. Think about it. Having a CPU which will pop 900+MHz for less than $70.

Pardon me if this is a stupid question, Mac. Like you, I did and redid the pencil trick but still couldn't get it to work. Thinking of getting a defroster repair kit. My question: Do you just apply the defroster compound over the pencil marks, or do you something clean out the pencil marks? I assume using the rubber eraser tip of the pencil is out of the question, right?

 

[jinsonxu]

It has been my understanding that a clean new eraser does the job for the pencil.
