PIII 800EB - please help identify problem

[Ciastko14]

Ok, here's the deal. My PIII 800EB is overclocked at 930 with the bus settings as follows. My default FSB speed is 133 mgz. I'm using a 4/3/1 ratio for FSB/DRAM/PCI to overclock. FSB - 155mgz / DRAM - 116mgz / PCI - 38 mgz. I have one 256 M SDRAM chip rated at 133 mgz, an ATI Rage 128 Pro 32 M video card, Sound Blaster Live Value and a standard Network card. If I try to raise the FSB any higher, my computer won't boot to windows and scrambles up my data. My chip is cooled real well with an SK6 hs and fan with 4 - 80 mm fans. I upped the voltage to 1.8 with no luck either. CPU temp is at 38 c load. I don't think cooling or RAM is the problem. I'm really stuck here. I believe with the cool temps I'm keeping, I should be able to push the overclock up to a GIG. Anyone have any insights, suggestions or thoughts as to what might be preventing me from overclocking any higher? Thanks for your help:burn:

Scrambling the harddrive is a sure sign that the harddrive hates the high PCI bus speeds. What harddrive are you using? Seems like the IBM 60GXP series harddrives are one of the best for extreme overclocking right now.

Thanks for the advice. Right now I'm using a Western Digital hard drive. I plan on doing a little bit of research into the quality of this drive. Are there any other brands of hard drives that you would classify as being "overclockable"?

I never had all that much success with Western Digital drives and one totally crash on me once. I've had fairly good luck with two of my Maxtor drives. However, I did scramble the 7200 RPM 40 gig drive once at 40 FSB, but it reformatted ok and I'm still using it now (months later). I recently bought two 40 gig IBM 60GXP drives and I love them (quiet, fast, reliable, and very overclockable).

Well batboy, it looks as if I've identified the problem. I'm typing this note to you at 1.002 Ghz! Popped in an older hard drive that was lying around, reinstalled and boom!! running a 166 FSB! I think I might go and pick me up one of those IBM 60GXP drives. Been hearing a lot of good stuff about them. I'll see how much higher I can go! Thank you very much for your help!
