Am I pushing it

[#3# RIP]

I've been overclocking(slowly) now for a short time now. I've been learning(on here and on my own). I got my P3 800e to 992 (124x41). I had to get some good mushkin 133 rev 3 memory to push a little farther. So far things are good. I had some cooling problems that I had to overcome.... --after mods---(22c--Idle)(34c--Full load) I achieved this by modifying my case. Putting in car audio systems is what I do for a living so access to materials was no problem. I installed 1 120mm fan in the side of my case, and that moves some air!!!!!!!Wow....Anyway here's my question; at 124 X 41 how dangerous is 41mhz on my PCI-(HDD) devices? ..the system seems to be rock solid

41 MHz is a bit dicey. That's a bit high, and wierd things have been known to happen, like data corruption, etc....

You are really close to 133 FSB, where the buses would all fall back to normal speeds. I'd bump the vcore up another .05v and see it you could get there. I'd think that chip would make it to 133....

Mr B I found a setting in my bios for 124 X 31@8x is 31 ok or is it too low???

USE IT !!! Better to underclock this than overclock at 41 MHz. Good find.

I was running a PCI bus of 42mhz and had all sort of problems. I would get Bios Checksum errors every time I would restart my pc. And the system would not post half the time when I tried to start it. I never thought about it being my PCI bus untill I started troubling shooting. I took all cards out and put them in one by 1. as long as I didnt put my PCI modem it it ran fine. But as soon as I put that in The problem came back. Thats when I thought about the PCI bus running to fast.

Another thing I had a problem with was Burning CD's. I was running my system at a FSB of 120 a while ago. Now I run at 126mhz FSB. Well since I changed it I could not burn any disks reliably. Well turns out I had to slow my DMA modes to 2 for both of my drives. Now it works perfect.

Is there a particular reason that you have for running the PCI Bus at 41.3 Mhz? The P3B-F gives you the choice of two PCI Bus freqs at 124 Mhz FSB: 41.3 Mhz and 31.0 Mhz. 31.0 Mhz is below the spec PCI bus freq of 33.4 Mhz. Read the P3B-F's manual, it won't hurt. I promise. If you don't have the hardcopy manual, just DL it from http://www.asus.com .

Edit. Oopsie! Looks like I should follow my own advise, substituting Forum for manual!

Yeah, underclocking the pci is O'tay. I have had mine running at like 29 for an extended period,no probs. Of course I've had it running at 41 with no probs on my old BH6 also :)

PCI bus at 41MHz is bad. Ran my system at about that for several weeks with no problem .... then my modem decided to start eating itself. Dial-up is a real pain when the best you can get is 21.6 and you're use to getting 48 :(

I am currently running at 45mhz PCI with no problems. 133mhz with 1/3 divider....

I don't have any pci peripherls in my system but wouldn't you know it my hardrive won't run on a 41mhz fsb, I have to move down to pio mode 2 before it works which is too slow to make a 41mhz pci bus worth while
