What happened to my 1000MHz Duron

[Keith]

I am new to overclocking and I recently decided to see what I could get out of my 600 Duron/ Abit KT7. I pushed it to 700 then 800 and finally settled nicely at 10x 100 with a $9 TCWO fan and heatsink :) . Temps ran about 43C idle and under a benchmark load it made it to 49C. It ran fine for 3 days, then I decided to push it to 10.5x and it seemed to work as well. I then tried to up the FSB to 103 and it did not like that at all. I set it back to 1000MHz and it would post but hung during Windows loading. The highest I could get it to run then was 850 without hanging. I re did the L1's and still had the same issues. Yesterday I managed to get it to 900 and it ran fine until I rebooted at which time it would hang in Windows. Today i managed to get it to 1000 again without hanging, but once again after rebooting it would hang. I have played with the voltage and it actually idled today at 39C while at 1000MHz and voltage at 1.75. That is the lowest voltage I tried running. When I first got it to 1000 it was at 1.825. I tried increasing it, but I get the same thing.

What happened? Could this be a power supply problem? Any help would be appreciated.

not sure but it:
could be the temps they are alittle high for me my duron700@950 runs at 44 full load
could be power supply what wattage is it dont use anything less that 300w and i would try a 350w if it lower than 300w

and try raising the volts a little my 700@950 runs at 1.700vcore
hope this helps i dont no every thing but other people do!!!
check other peoples volts on list 1.625 seems very low to me
good luck

I've managed to run my Duron 700 @ 1000 but it does't boot into windows with 1.75 volts then when I tried with 1.85 it went into windows fine so now it's runing stable but a bit hot @ 47c.
I don't think it's the fault of your power supply cos it worked before. U might have to bump the voltage to 1.85 to get the gig but be sure U have adequate cooling so that the CPU stays in the low 40's.

Kick The Voltage Up By 0.5V at A Time But Be Careful Or Else..... :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :(

I've got it at 1000MHz right now and it runs fine for the most part. In fact it has been running for like 15 hours, because I know if I shut it down it will have the same prob :) According to VIA hardware Monitor, the VCore is now at 1.95, is that a little high?

Also, it is locking up during 3DMark2000 now. It will not make it past the 64MB Texture Rendering where it would before. In fact it froze earlier in the test last night at 850 MHz

yah it's a little high but it's normal. :) for some reson via semes to up the voltage buy .1volt. owell all the better for us :)

with a homemade water cooler i was able to get my duron 700 stable at 1103MHz. blue core, 2.20 vcore 100%stable 29C idle 44c load
4L water tank
heater core for a rad

Well i would say, put a good heatsink on there, when you are going for 1000mhz you should get an alpha or something similar, and of course arctic silver. i might even recommend a dts-400 copper shim to go with that cause those alphas have pretty tight grips! I took 2 tiny little chips of the side of my t-bird 1-ghz EEEEEK!!

I ordered a FOP38 for it. Hopefully that will get the temp down a little. Damn, now I can't get my burner to work though :( I must have screwed something up.

Run the Prime95 Self Test w/Round Off Checking enabled. If it can run Prime95 like this for a good amount of time then your system is stable. If it fails then your system is not 100% stable. Prime95 will fail before any other application that I know of. More than likely, you'll have to drop the speed down a bit from your max overclock in order to get P95 to work well.
