Overclock denied: Mobo or CPU?

[spdracer22]

Ok, I'm running a Soltek SL-75DRV4, Athlon 2000+ (.18), 512 DDR 2100, and a Radeon 8500DV, all under WinXP.

I have had the CPU stable enough to run PCMark 2002 at 1824MHz (152 FSB @ 12 mult.) without a problem. When I try to push it higher, though, I get a "fuzzy" almost TV static-looking screen before the Windows boot screen. After that, there is no problem until it tries to load the programs designated to start up with windows. Then it locks up.

I have been trying to find a voltage mod for my Soltek in hopes that I can push it higher (I'm running 1.85V now), but I'm not sure if the 2000+ will go. I've heard (from a Tom's Hardware article, among other places) that 1800MHz is the limit on the .18 process. But, since I have had it 24Mhz over that "limit" with no problem, it leads me to believe that the motherboard voltage is more the issue.

If anyone has any thoughts, let me know. I'm new to overclocking, but I'm willing to try anything.

Does this sound like an AGP or DDR problem? I increased the AGP and DDR voltage, but it doesn't seem to be helping...

I'm not sure what the performance advantages of a higher FSB to a higher multiplier are, but I have heard that the higher FSB is better...???

Higher FSB better.
Your memory might be holding you back. I know my PC2100 memory doesn't like it when i set the FSB past 151.:t

Do you know what dividers you're using with your FSB set higher? The problem could be just about anything (CPU, memory, AGP, PCI). If possible, try to use dividers to keep everything else in spec aside from one component (e.g. memory or CPU) and see how high it will go. Also, you could try stripping down to a minimal system (remove any PCI cards that are not necessary) just to test how high you can go. The idea is to try and see what component is limiting you at the moment. Even reducing to a single stick of RAM might help.
