duron overclocking. Still possible?

[Guest]

I have had a brief look at the article "Overclocking AMD's Socket Processors" (july 11 2000) and from this is seems I can just make or break a few bridges on the duron 800 and my jumperless motherboard will boot up with the new clock multiplyer.
I read in a later article "Modifying an Asus A7V Motherboard For Duron-Overclocking" (August 8 2000) that this motherboard needs scary sounding modifications because of new multiplyer locked CPU's.

Is my recently bought (within the last 4 months or so) duron 800 overclockable or is it's multiplyer truly locked?.. If this is the case.....

I can run FSB at 112 but anything higher just gives me a black screen. Would stepping up the voltage help me achieve
133*8=1064 that I desire. I know she'll run hot because for a while there I had stuffed the heatsink allingment and it was stable at 90 degrees Celcius.

thankyou.

First of all don't run your cpu that hot! If it doesn't destroy it right away, it will hurt the life of your processor. To change the multiplier your cpu must be unlocked (L1 bridges must be connected). The actual changing of the multiplier is usually done through the bios or jumpers on the motherboard. I'm not familiar with yours so consult your manual or download one if you lost it. If you overclock the FSB don't expect to hit 133. Durons are 100MHz default. I've heard of some hitting that number but who knows if that is true. I just oc'd a 100x8= 800MHz Durrie to 905MHz by changing the FSB to 113. I hit 120 but it wasn't completely stable. I think atleast 115 would be ok but this machine is for someone else and I need a completely stable system so I bumped it down a lot to 113. Increasing the voltage will help sometimes. But make sure you pick up a good hsf, not the one that AMD ships you. The best way to OC is to figure out how high of a frequncy you can hit by adjusting the multiplier. Then, lower the multiplier back down to stock, bump your FSB up as much as possible and then adjust your multiplier to get close to that maximum frequency setting. Download some programs/utilities like Sandra, Folding@home, Prime95, etc. This is how I stress test. I run Folding@home and some vid card benchmarking utility (forget which one) and then open up a ton of MS Explorer windows. Then I let it run for a bit and then try to close all the windows and the utilities. If everything is clean I consider the OC to be stable. Hope this helps.
