I had a perfectly stable system with a 600E running at 900Mhz with a P3V4X motherboard (1003 BIOS w/ ICS clock gen chip). I accidentally shorted out the mobo and replaced it with another P3V4X (1005 BIOS w/ Winbond ICS clock gen chip). I also upgraded my video card (went from TNT to Radeon 32 MB DDR) and hard drive (went from WD to Maxtor) at the same time.
Then I couldn't even post at 900 MHZ. Figured out it was a PCI speed issue because anything over 35 Mhz PCI speed wouldn't post. Even the lower FSB settings that use 37.5 Mhz PCI wouldn't work, but higher FSB settings were fine as long as they used nothing higher than a 35 MHZ PCI speed.
I thought it was the Maxtor, but I just replaced it withn an IBM Deskstar and I still have the same problem. The only components I changed were the motherboard, hard drive and video card. If its not the hard drive, then it has to be a limitation of either the Radeon or the new motherboard. However, the Radeons reportedly run fine on overclocked AGP bus speeds, and these newer P3V4X boards with the Winbond clock gen chips are supposed to be much more stable than the older boards (thye older board gave me 900Mhz). The only other thing I can think of is that I shorted out the old mobo through the Soundblaster Live. The Soundblaster Live still seems to work fine, but maybe something happened to it that won't allow it to run on a higher bus speed now?
Any ideas? Sorry for the long post but I really want to try to get this system back up to 900 MHZ. Thanks in advance.
