CPU Speed lolocaust extravaganza
After some poking around today, I finally solved the mystery of why my processor was working at a speed far slower than it should have been.
It turns out I had my CPU FSB set to 100Mhz instead of 133MHz, thus making my Athlon 1800+ run at 1.15GHz instead of 1.53GHz. So, I set the jumpers on my motherboard so that the FSB is running at 133MHz. However, after I did that, I could not boot into Windows. Almost as soon as the splash screen shows up, it will blue screen, displaying what appears to me as a random STOP error (they were different every time, from 0x0000008E, 0x0000007B to 0x00000005. Those just appear entirely random to me, considering Micrsoft says somewhat different things for all of them.) Completely ignoring these BSOD's, I try my Ubuntu 5.10 live-cd, to no avail. when I try to boot it, it would stay at decrompressing the kernel, or giving an immediate kernel panic. I tried flashing the BIOS (even though the manual says it fully supports my CPU,) and that did nothing noticable. When I put the FSB back to 100Mhz, everything acted as it should, just with the processor not running at it's max speed. So, how would it be possible for me to keep my motherboard running at 133MHz, yet be able to actually use my computer? Note- yes, I did take out sticks of RAM and swapped them out to see if it was just some weird memory issue, to my knowlege, it isn't. It also isn't a heat issue, the case is sitting wide open,and the power supply is sitting on top of the case. CPU: AMD Athlon 1800+ Motherboard: Soyo K7VTA Pro V1.0 (I just call it the POS-1) Jam it back in, in the dark. |
Just curious, but how did your processor change from stock speed to snail pace?
Have you made sure your HSF is seated properly with new thermal goop? It happened to me last time I took my computer apart. :/ Be sure to double check your voltages for RAM and CPU, and make sure that your multiplier is set to 11.5X for that CPU. I might also suggest testing other hardware such as a new PSU, different mobo, or different CPU. There's nowhere I can't reach. |
Doesn't RAM have to be able to run at the same speed as the FSB? Are you sure yours does? It may also just be Windows acting wonkey over you changing your hardware configuration. Got a Linux LiveCD you can try out? Those're always helpful.
This thing is sticky, and I don't like it. I don't appreciate it. |
Also, although mobo's "support" stuff, POS mobos are very picky and quirky. So you might be screwed. ![]() Other than that, my initial reaction is memory issues. Your memory timings might need to be changed now that the FSB is faster. I don't know much about tweaking memory, except that higher numbers are generally easier on the memory than lower numbers (ie. 3-3-3-6 is VERY tight timings, and 3-5-5-6 is loose). So you might try to custom time your memory a bit in your BIOS.

100MHz * 11.5 gives you 1.15GHz 133MHz * 11.5 gives you 1.53GHz
The voltages are correct.
I was speaking idiomatically. |
Did you change the FSB settings in your BIOS to coincide with the changes you made on jumpers?
How ya doing, buddy? |
I'll have to look into that.
I just assumed that the BIOS was properly IDing the CPU (in 100MHz, it reports as "AMD Athlon 1150MHz," in 133MHz it reports as "AMD Athlon 1800+") that there wasn't much to do in the BIOS. Sometihng I definitely shouldn't have overlooked. FELIPE NO |
How ya doing, buddy? |
I'd figure that would be true, but I've had some motherboards that require changes on both jumpers and in the BIOS for other options for some wacky reason. There might at least be some other option in your BIOS that could set this straight, too.
Most amazing jew boots |
Yeah, I thuroughly checked through the BIOS setup and there's nothing about setting the FSB in there.
And on the manual end of things, it only says to change two jumpers, and that's it. How ya doing, buddy? |
