My journey to oc the Duron

[thehandler]

I have just started to oc my Duron 600 which is an unlocked cpu from Overclockers.com.
I am running a new style FIC mb with the KT-133A third revision chipset. It is a good mb and seems to be oc friendly now as well as have ultra ata 100 support and 4x agp as well as 266fsb capabilities. It has dips for FSB as well as core v and mulitiplier.
I am currenlty at 800mhz and it is failry stable but not fully and that is what I am trying to solve.
I have not bumped the fsb up yet from 100. I have the multilier at 8x. The system would not even boot windows unilt I raised the core-v from the default 1.60 all the way up to 1.82. It became more stable as I approached the 1.82 which tells me it may even become more stable if I bump it up further to say 1.85 or so. I am worried however about the heat issue of the CPU. at idle, it runs a cool 38C. but while gaming heavily. it runs more like 40C. Then when the system freezes or locks, it runs as high as 45C.
I seem not to be able to bump up the fsb more than say 102 before it becomes unstable. I am trying to get to around 900 reliably. The reason I am so hesistant to raise the core-v any more than needed is because when I first started playing with it at 600, I was able to run the fsb up to as high as 110 and left the multiplier at 6x but it actualy became unstable because the core-v was TOO high at like 1.62 so once I bumped it down to 1.60. It ran great at 660mhz. So I am worried that at 800mhz and at 8x, I will reach a point where my core-v is once again too high and will start to hinder me rather than help. It seems to be a rather precarious relationship between these 3 variables no doubt made more unpredicable by the variations in mb's. There is not a lot of help I can get from other guys becuase I have not found anyone else as yet using the new FIC mb. Please help a newbie. thanks MIke

I don't have that board. But there was one thing in your sig that could account for the high temps - the chrome orb.
The orbs are O.K. for non o/c boards - but are not up to the task when you want to reach the speeds that you want.
Why don't you replace it with a ThermalRight SK6, or a Millenium Glaciator, or a GlobalWin CAK38. These HSF's can get your temps down so you can run the higher voltages.

First of all, Welcome to the forums.

I have both a couple of DURON 600's and a couple of FIC motherboards. Although I don't have the AZ11E with the KT133A chipset I do have an ASUS A7V133 with the KT133A chipset and have had very good results with both of those DURONS running at the 133+FSB. Keep in mind that when you get to the higher bus speed the divisor changes thereby bringing your PCI bus into spec.

Since you have the KT133A chipset, I think that you should take advantage of the higher bus available and increase your entire system performance and stability as well. I would think that you should be able to get 8.5*133 with adequate cooling and an increase in the Vcore.

I also agree with the above post concerning the cooling issue. The "Orbs" haven't been accepted as an adequate cooling solution, not to mention the problem with their propencity to crack cores. I've had these DURONS to 1100+MHz using Global Win FOP 32's, having since migrated to the newer and more efficient Global Win WBK38's.

By the way I have an AZ11, one of the first socket A motherboards and although very stable, not much there as far as overclocking potential. I also have an AD11 and as much of an improvement it is over the AZ11, I don't think that it can compare to the boards I have from ASUS. And a bit pricey to boot.

Good Luck!
