Hi, I have a Duron Applebred 1800 processor. I have the bios set at 145/36 now yielding a 1957 mhz overclock (stock is 1800).

The motherboard is an ASUS A7V8X-X

I have not messed with VCORE yet, not sure if I want to risk it or not.

I have DDR 2100 Ram Kingston.

If I increase the CAS latency from 2.5 to 3, I can go farther in my FSB adjustments, correct?

To be absolutely 'safe' what is the max you'd do if you were me? Temps are 42c now, and it seems stable (ran through Prime 95 for a while)

Here are my Prime95 benches for those interested. . .

AMD Duron(TM)

Buy some Corsair XMS or Kingston HyperX PC3200 or OCZ LL memory, if you want to see what it will do. Your motherboard doesn't have pci or agp locks, it has dividers, so you will have to jump all the way to 166 or 200fsb, so the pci bus will stay at 33mhz.

I'm new to this. I am assuming that the 145/36 I am running at now means that I am utilizing a 145mhz FSB and that I have increased the PCI BUS to 36 mhz.

I really can't afford new ram right now. Given that limitation, how much farther would it be advisable to take things as they are? I don't want to damage anything is my main concern.

I see what you are talking about with the jump to 166. I can select 2250 and then the bios defaults to 166/33 -

So that means if I am understanding this that my memory would have to work at 166x2 instead of what it is rated for 133x2. Now the question is can my Kingston Value Ram do 166x2 without damage? I remember reading that if you raised the CAS latency, it lets you get more mhz out of the ram, so if I go from 2.5 to 3 on the CAS latency, would this help?

Would ppl here advise me to try the 2250mhz 166x2 overclock?

Thanks!

Let me know if I am not understanding this correctly . . .
