Duron @ 1.87v?

[Guest]

Hi all,
I have a Duron 700 which I used to overclock to 950, with Vcore 1.85. Today I experienced some annoying problems; right after boot up (dekstop wallpaper displayed), my machine would blue screen with fatal exceptions in module VFAT (once VCACHE too). All nice and well, so I downclocked it to 900, and it was stable. Now I have it back at 950, but with Vcore of 1.87. Is that healthy? I've read the Duron spec PDF from www.amd.com, and they say the recommended don't-go-any-further-than-this maximum is 1.75v. Should I listen to this?

I'm using EPoX EP-8KTA+ and Elsa Gladiac MX (GeForce2 MX), by the way.

Another question is, my CPU temp (even at 1.85v) only gets to 41 degrees Celcius (106 F). Is that right? I've read (and saw myself) that with Asus motherboards, the reported temperature is about 55 degs (131 F), while with EPoX it always stays between 25-35 C (77-95 F). So, should I believe that my CPU is running at 41 degs?

I've built 4 systems (for friends), 2 with Asus A7Vs, 2 with EPoX EP-8KTA+, and that's where I got my stats.

Well, I hope I didn't confuse you. Please comment!

AMD's maximum voltage rating of 1.75V is the max that the chip will safely handle without damage. Anything above that, all bets are off and your on your own as far as warranty is concerned. Of course by connecting the L1 bridges, your warranty is bye bye anyway. Will it take a higher setting and still work OK, probably. I run my Duron 600@950 at 1.75V. I can bump it up to a gig with 1.80V but I'd rather play it safe as 50MHZ won't make a whole lot of difference at this level.
My cpu temp runs about 38-40C after several hours use. Case type and design will play a role in the final CPU temp; I have a mid tower Enlight case with an additional case fan.

Well, my Duron 700 is quite stable at 900 and 1.85.. it annoys me how other people's (like your) Duron 600 can go to 1 GHz!! I guess I have MHz envy.. what factors are involved, do you know? Is it just luck, getting the right batch of processor? What motherboard do you have, by the way, and how did you connect the L1 bridges?

Well, I wonder if my processor's going to meltdown anytime soon.. if so I'll probably buy another one (the prices have gone down so that I can just get 750 or 800 for the price I got my 700), and then overclock it some more.. haha.

I got a noisy cooler (it was the largest, fastest, and most expensive Socket-A cooler), but well I don't think I don't get what the noise is worth.. although well, 700, 900, what's the difference anyway when all I do is rant on this board.. hehe. My CPU gets to 38 degs nowadays, I used to have it at 950 at 41-42, it was stable for a while, but it started crashing 2 days ago.. oh well.

Luck of the draw would be the #1 reason I would guess. After all, AMD rated my cpu at 600MHZ; nothing beyond that is guarranteed, so anything over 600 is a freebe as far as I'm concerned. Most of the 600 lot chips seem to have no problem running at 800; some hit 900 and a few make it to a gig. I doubt that I would be able to notice a difference between 950 and a gig on my system.
I used a "Circuit Works" micro tip conductive pen to connect the bridges. It's liquid copper based used for pc board repairs and it's permenent; one mistake across the wrong bridge and you can deposit your Duron in the nearest trash can. I have a pretty steady hand and a large magnifying glass. I personally prefer this to the pencil trick.
My MoBo is a Soyo K7VTA-B with 256M PC133 cas2 and a cooler master 6H51 hs/fan.

On my Duron 600 (Epox Ep-8kta+) I connected the L1 bridges with an automotive rear defroster grid repair kit made by locktite. It is copper based resin also...I had a lot of trouble getting them connected exactly as I liked...and I used Acetone on a paper towel to remove it immediately if I was unhappy with it (I think it would remove the conductive pen too if used immediately). It took me about 8 tries with the toothpick I was using to dip into the conductive resin.
I was able to clock it to 800mhz with the stock voltage...so I kept it there. I know it would run 900 or 950 if I upped the voltage...but I lost a K6-2 once doing
that so I'm relunctently holding myself back...even though I know there is plenty of headroom built in for voltage tolerences.

Hi, I've taken a Duron to 1.9 volts and have seen no problems so far. I would recomend that you get a very high quality heat sink for voltages this high. The chip is stable at 1010mhz
