This is from a very amateur overclocker so any pertinent advice or sharing of knowledge would be appreciated. :-)

I have an Athlon 950MHz (200Mhz FSB), an Asus A7A133 (specs here: http://usa.asus.com/mb/socketa/a7a133/specification.htm), and 384MB of PC133 SDRAM. I setup a ghetto passive water cooling system that keeps this CPU overclocked at 1137Mhz under 48º C (119º F) under a full load. That’s better than my quiet air cooling setup, so I’m not complaining. I’m running Windows XP Home.

Everything in Windows runs fine when I have the ‘CPU/PCI Frequency (MHz)’ set to 119/40 (1137MHz) in the BIOS. Once I go to 120/40, then I start to get blue STOP screens either when Windows is starting or when I start to put a load on the CPU within Windows. Here’s a shot of the BIOS screen. Sorry for the bad quality, but it is from the Asus .pdf manual.

My settings for this BIOS screen are as follows:
CPU Speed: Manual
CPU Frequency Multiple: 9.5x
CPU/PCI Frequency MHz: 119/40
CPU/Memory Frequency Ratio: 1:1
CPU Vcore Setting: 1.85V

I think the multiplier on this Athlon is locked because no matter what I change the ‘CPU Frequency Multiple’ to, WCPUID always shows 9.5x in Windows. Here’s a screenshot in Windows:

Do these blue STOP screens mean that I have reached the limit for this CPU? Is it the motherboard that’s causing this? I don’t think the cause is the CPU over heating because it runs at a reasonable (not excellent) temperature when set to 119/40, therefore 120/40 shouldn’t heat the core that much to cause blue STOP screens. So, I’m assuming that it is either the CPU or motherboard, but I’d like to know what exactly about the CPU or motherboard is causing the blue STOP screens so that I might be able to overclock even higher.

Any helpful suggestions would be appreciated.
