Duron 800 at 1050- Seems I've reached the Limit!?!

[Natemeister]

First off- Thanks to this and other forums I decided to switch over from intel to amd and try overclocking- It is a lot of fun and I love this stuff!

Here's my set up:
Abit KT7-Raid
256 Meg Crucial PC 133 cas 2 Ram
Alpha PEP 66 Cooler ( W/Delta 38 CPM fan)
Antec 830sx case with four fans

OC'd using multiplier only 10.5 by 10
Voltage bumped to 1.80
CPU Temperature Running at 113 F (currently running a burn in /stress program continuously)

BTW- the antec case, Alpha pep66 cooler and Artic silver made a big difference on the cpu temps ! Apple to Apple running at 1Gig overclocked my previous case averaged 109 to 114F cpu temps - this with one side of the case off!

I ran it earlier this evening at the same 1 gig in the new antec case bla bla bla- and the temp of cpu averaged 102 to 105- with the case closed up!

Even running at 1050 and volts upped to 1.80 and running a burnin program my cpu temp is 111F ! Much better than when I ran at 1 gig in previous case and sides off for coooling. Incidently, the cooler I used before was no slouch - Alpha 6035.

I attempted 1.1 gig thru multiplier only and tilted my bios - had to let it sit for five minutes before I could boot up and throttle back. Whats the deal here? When I adjusted the multiplier to 10.5 by 10 the system would not boot and gave me a weird mesage , something like "error unable to read media in drive A or something"?? Anyhow- I shutdown for a few minutes and was able to fire up and get into the bios to throttle back.

Also BTW- using the permatex rear window defogger fluid to unlock my little ol oem duron 800.

Anyone - how much higher can the duron 800 go past 1050 ??

Thanks People!

Oh BTW,

Throttle my duron 800 back to a mere 1gig using multiplier adjustment only and lowered volts to 1.74.

This is real stable on my system ( been running for a week).

With my new case, pep66 alpha cooler and artic silver my cpu tem is currently 102F but should range up to 105F. Motherboard temps range between 71 and 75F.

Mucho better than the same configuration in my old case and alpha 6035 (no slouch of a cooler). In the old case I had to keep the side open and still my cpu averaged between 109 and 114F !

Those temps are pretty good at the moment, so you ought to be able to get a bit over a gig with it (though it does depend on the chip). If the chip works fine at 1000, gives error messages at 1050 and doesn't post at 1100, that would suggest it's limit with your cooling and voltage is somewhere between 1000-1050. Try using the fsb instead of the multiplier, see whether the chip maxes out between 1000-1050. The burn-in you're giving it should help, so give it a few days and hopefully it'll push higher.

I have a 800 Mhz Duron CPU... 3 steps of overclocking:

1. ive tried the Titan Orb- Silver.. runs perfectly at 800, it melt at 1000 Mhz
Conclusion: -> big crap
2. Then I bought a Neng-Tyi Fan, working at 7200 t/min, it blows pretty much air on the CPU... I´ve reached 950, and sometimes 1000 Mhz at cold, dark winter nights...
Conclusion: good, but thats not 1 Ghz
3. Bought the Alpha PAL 6035... heard of it, got some reputation...
at 1,77 V i easily reached 1Ghz...it was too easy....****ing good fan...
at 1,8v i got the 1,05 Ghz, but it´s only stable when I open the case so....
forget it...
Then I tried to change Fsb. With CPUCool (good overclocking prog from PODIEN) i reached 1,06 ghz (very stable) and 1,08 during 5 hours...

Duron proc.. kix asses

slow your memory timing down a little this might help you to push the FSB a little more when i did this i was then able to run at 113and 114 ;D

it's not impossible that you've reached the limit of your chip. my chip's hit a wall at about 1150 (it's a 600), and not even 0.2v from the voltage mod could help. if you have reached the chip's limit, then no amount of coaxing or burning-in is going to get it up. i think be happy that you got it that high with that amount of voltage, and start planning your next system! ;)
