Last night I decided to push my new system for the first time. I completed the build last Saturday and it has been running sweet since then. I tried to raise the bus speed up to 230x10 and it ran at 2300 without problems. I then tried to up it to 235 and the machine locked. I rebooted and lowered the HT multi to 4x. Rebooted and it came back up ok. Not happy with this (hey why not you hear of guys hitting 2.7GHz etc) I decided to try 2.4GHz (10x240). This resulted in the machine getting to the point where it would load the XP boot strapper and go no further. I then went back into the BIOS and upped the CPU voltage to 1.425v - same result. At this point the HT bus was running at 940MHz, locked PCI at 33MHz. Temps were ok during this time also.
I decided to give up and play some Oblivion at stock speeds again and read up a little more about clocking. Upon rebooting the machine and loading into Windows, I discovered to my dismay that audio would play at around double the speed. I also found that my USB devices were being picked up as unknown devices, printer, mobile phone, keyboard and mouse - Anything I tried.
At this point I thought no biggie, its just drivers that are corrupt or ive not locked a certain bus and its corrupted data etc. A few hours later and 5 OS installs (XP, 2K, W98, Fedora and Ubuntu live CD) I discovered that this was a universal problem through all OSes. I fairly quickly decided that the problem must lie with the hardware. I tried a PCI sound card. All was well. PS/2 mouse without problem too. I then went back to the BIOS and loaded defaults - same story. I then flashed BIOS (it was at the latest rev already) - no change. Pulled the battery and shorted the clear CMOS - no change.
8 years as an IT Engineer and I havent damaged anything through overclocking. Could this be my first casualty with such a tame clock? I think it may be the southbridge on the board that may be defunct. I stripped out the motherboard and went around it with a magnifying glass. There is no visable damage on there.
I ran memtest86 from a bootable CD. There is no problems there.
I then searched the web for a few hours but have yet to come across someone with the same problem. Has anyone experienced this? what was the work around? At the moment I'm at work and the motherboard is in the boot of my car (its on its way to get swapped at the shop at 2pm).
Machine Spec
AMD X2 3800+ Skt 939 (Stock Cooler)
Asus A8N-E Nforce4 Ultra chipset
2x512mb Samsung CL3 DDR400
XVision 7600GT @ 615/1660MHz
Hiper 580Watt Modular PSU
2x80GB HDD's (WD and Seagate) - soon to be 320GB 7200.10 Seagate
Liteon DVD-RW
Thanks for listening, any input appreciated.
