Display hell...

[Brian R.]

I have been trying to push the envelope of fsb on my computer (see below in sig). The current hang-up is a completely unintelligible display after a few minutes of running in Win2K (from the IBM ATA66 drive), usually while running IE 5.0 and SETI (background) simultaneously. Another symptom is I am unable to run UT at 992 MHz (124 Mhz fsb). UT gives me a general protection fault during load-up.

I have just installed the latest BIOS for both MB and HPT366. I am one BIOS revision behind in my MAX.

The BIOS update to the BE-6 and HPT366 improved my stability, but I'm looking to get past this video hurdle. Any possibilities anyone? I'm going to update the MAX BIOS, but I don't hold much hope for that. Running at AGP 1x has no effect. Also, the processor seems to be running quite cool to the touch.

Have you tried bumping the CPU core voltage up to 1.8v ????? I've been running my P3-700 there for several months with no problems at 124MHz FSB.

Not recently. I used to run it at 1.80 when I first installed it. As soon as it would boot at 1.75, I lowered the voltage. When I ran 1.80 V, it was not stable either (sort of like now). I guess it's worth a try. It runs so well and cool now (except for this periodic lock-up) that I think the processor is not the problem.

try switching to udma33 slot instead of udma66 and see if that helps

What changes (other than the cable) do I need to make? Any idea?

[lindberg]

Check in your bios on the setting for your ide channels, but the motherboard is probably smart enough to see for it self and detect DMA33, BUT you don't need to change cable if you change in your settings in the bios! Just set to mode 2 instead of 4
But why would you even want to go to DMA33 when you have DMA66, The system speed isn't all about CPU-frequency. Your computer will probably be slower (overall) if you get it stable with DMA33.

Try lowering your Memory settings.. I should say raise you memeory timings.. 3-2-2, often times Even good ram won't work well when there is more than one stick... besides it takes a few seconds to test...

I'm running a 650E@910 without a prob... are you running the PCI bus at 31 or 41?? some mobo's have a choice between the PCI clock divider...

Some people have found the HPT66 controller to be the weak point in their systems as far as overclocking goes. I need to try the ATA33 controller to see if it offers greater stability at 124 or 133 MHz fsb.

Anyway, I have found only a little difference in HD speed between ATA33 and ATA66.

Actually, I'm beginning to think IE 5.0 is the problem. It only crashes while running this program. (Won't start UT). The computer ran all night with SETI at 992 MHz without crashing. Seems to be fine without IE running.

Stringy - I have tried the various possble memory timing settings and have found no difference. Maybe I should try only one stick of memory...

My PCI bus is at 41 MHz. I lowered it to 31 MHz without seeing a difference. Still unstable.
