Overclocked Duron 800...how fast will it go?

[Amd2k]

Just wondering what the limit may be on o/c this cpu. As before i had mentioned that my temp is around 59c. Although i am using the AsusTempster to get the reading. Is there a way to get a more accurate reading? The system clock is at 100mhz....should i be increasing this?

We need the coding on your chip. Your temp is kind of high. My 800 Duron AKCA0109, week 9 of 2001 oced to 7.5x140=1050mhz very stable on the KT7A mobo, 256M crucial RAM. The idle temp is 30C,
full load temp is 39C. You need good HSF and also good case for good air circulation.

First of all, welcome to the Overclockers Forum.

The best advice I can give you is as has been said many times before, "research". Before you can expect to achieve satisfactory results, you have to do your homework. You have to read everything that you can get your eyes on that pertains to your goals. There are a lot of potential pitfalls that could make this a miserable experience, if you don't have a good working knowledge of your hardware and at least the basics of how it works. This doesn't mean that you need a computer science degree, just the basics. There are a lot of people in this forum with many years of experience modifying and improving computer equipment. Sometimes a one paragraph answer may not give you all of the information that you need, sometimes it is assumed that you have an understanding of what's going on to begin with. Keep in mind that you are dealing with a very sophisticated and expensive piece of electronic equipment.

One of the best places to begin your journey in the quest for knowledge is located right on the home page of this site under "BEGINNERS GUIDE". From there I would suggest that you familiarize yourself with the "CPU Database", also located on the home page. This page will give you an idea of what others are getting with similar equipment, voltages, cooling solutions etc.

That being said, I've built a similar system with a DURON 600 and got it up to 1100MHz, being limited by the Issues with the KT133 chipset that all first generation socket "A" motherboards have.

Congratulations! It looks you're off to a good start on this project, according the the "CPU Database" the average overclock of this CPU is, 968MHz.

On the temperatures you're seeing, given fact that it has been said that the ASUS Probe reports temps as much as 10C higher than actual, I think you're too high. Get rid of that hsf, the "ORBS" are known not to be that efficient to begin with, then there's the problem of cracked processor cores with them. A lot of people have ruined expensive AXIA's with them. I would suggest that you spend a bit of time in the "COOLING" forum of this page to get up to speed in that area. There are several good alternatives available to you, Swiftek and Global Win among them. I prefer a lapped Global Win WBK38. The additional fans that you have are sure to be a good thing, "IF", they are properly installed. Otherwise, they can actually hinder the performance of the hsf by disrupting the airflow within the case. This has been another area of great discussion in the cooling forum, blow in, blow out, negative pressure, positive pressure etc, etc.........

Once you get the temps under control, look to the FSB for the little bit more that you can get from this motherboard. As I mentioned before, the KT133 chipset has a problem with the FSB when it gets much above 107MHz, and not too many have been successful over 110. Forget about 133MHz or above.

You will probably have to increase your CPU voltage. There should be no problem if you have to go to the boards maximum of 1.85V, which will be reported as 1.92 by the ASUS Probe. Just be sure to keep an eye on those temps. I would say that if you can keep them in the mid 50C's (according to the ASUS Probe), you should be alright.

GOOD LUCK!

Research, the key to a successful overclocking experience!

Like Frank said take it slow. My personal recommendation is to spend some time burning in. I have had the Duron 800 for a month now on a MSI K7T Raid with FOP32-1 HSF and have reached 1070 at 1.825 vcore but very unstable. I have run some tests and mine is most stable at 1030 using 266FSB. Most of the Duron 800's that I have seen appear the same. Once you go over this the extra volts and consequent cooling needed are not worth it.
Good luck and learn as much as you can it's really great.

Bravo, FRANK.

I can only add that once you embark on overclocking..Notes are of vital importance. I have spent many hours searching for the right combination of elements to optimize a given set-up.(sometimes staying up far too late)

If it was not for my meticulous note taking, I am certain that what limited success that I have had while overclocking would have come at a much higher 'development cost'.

There is a management axiom that applies to many things in life.

"One minute spent planning, saves five minutes in execution". (those management seminars that I've been force-fed are starting to take)

Well, I have my Duron 800 on an Abit KT7E motherboard running at 136x7.5=1028mhz at 1.85vcore 3.6 IO and 48C under load (with Alpha and Arctic Silver). If you have a motherboard that only runs 100fsb, you should just bump up the multiplier to 10 or so after unlocking. If you DO have a motherboard that will handle 133, you should bring your fsb to 140+ and your multiplier at 7 or 7.5. MOST people max out at about 1000 mhz with these chips. I can get mine 100% stable at 1.08ghz, but I error out in Prime 95. The only thing I can tell you other than that, is that you should keep tinkering, tweaking, and trying until you find that perfect combination.

Oh yeah, hit a new record. In SiSoft Sandra 2000, I got my memory speeds up to 550/575 MB/sec! AND IT'S ONLY PC133 STUFF.

Tim.....here it is....my Duron 800....AKCA0043SPPW..hope that helps. Right now it is at 10 @ 100mhz.. voltage at 1.85v on the Asus A7V. Any tips would be gladly appreciated.....
