I'm benchmarking my O/C'd celeron. I keep getting an error message when running 83mhz. I found in the FAQs that this happens with too much bus speed. Is there a way around this? Or another benchmark program?
most celeron i know of work well at that speed. the only thing do be sure is the agp and pci bus speed adjust the divisor speed so pci is close to 33 and agp to 66.if you are too far from these speeds maybe its the source of your problems. i personaly have a celeron 366@550 = 100fsb so i get 33pci and 66 agp standard speed. tell us more about your setup

It will bench mark at 66mhz and 75 mhz, but at 83mhz the first helicopter test runs then the second starts then an error occurs. I think it said hud.vxd or something .vxd. I went to the site and looked under the faqs and it said the bus speed is to high.
I used to gt it locking up at 10x7 but it was fine at 8x6 so try it at a lower resolution
ok so 83 is an odd speed. I have the option of 1mhz increments from 83 on up. Is there a less odd speed? is 95 too high?
Think of it this way, nothing (as long as it will run stable...) is too high! I would love a board with 1 mhz increments! That has to be soo cool.
Basically, you need to watch your agp/pci bus speeds. The pci bus speed (ideally) is 33mhz. The agp is 66. Now having a slightly faster speed is cool, but don't overdo it, or you'll corrupt something.
So, keep an eye on pci bus speed. At 66mhz processor fsb speed, it should be right at 33mhz. At 100mhz fsb speed, again it will be right at 33mhz. At 75mhz fsb speed, your pci will be at 37.5mhz. @95fsb, pci will be just under 32mhz. Keep your pci bus speed under 4o, See, @ 83fsb, your pci bus speed is 41.4mhz. This is almost always too high...
I hope you can make some sense out of this mess, I'm kinda tired and looking back at it, well it's a mess... Sorry.
But do you get the idea? Keep going up with your fsb speed until it no longer will run stable, then drop it down say 2mhz. Run that for a while and see how you do. After running @ that speed for say a week, you may posibly be able to bump some more. Also of course, you may well have to raise the core voltage on your processor to help with stability. Just keep an eye on the pci bus speed, and you'll be cool.
I hope you find something, anything of help in this mess..
Wow, I've been enlightened! That was good info. I new to all of this and the best info I get is from this forum. All web sites about O/C'ing are old and outdated. I'll keep chuggin till I don't have any hair left to pull out.
thanks a lot
