Used to overclock, but now problems
I was overclocking a dual celeron 366 to 550 and sometimes more until last
summer when I had difficulty installing some software for work. I Regular clocked it to install and run to not have any problems. Now I can't set it back. I must have changed the numbers in my BIOS too much. So I tried the defaults and works for 0.5 - 3 minutes then I get a page fault in WinXP and reboot. Its a little better but not good enough. I am running 66Mhz OK, but want to switch to 100 to 110 Mhz instead and I can't even get the 100 to last long enough to even open anything up in Windows. The chips are running at 2.08 volts. BIOS numbers are 3 counst for CAS / RAS etc. Rich Sias |

I must have had something somewhat different last year when I could get up to 110Mhz. Although 105 was VERY stable and 110 wann't quite as good. Rich Sias |

Better yet, use speedfan and you can set it to throttle the HSFs once you get it running right. |

I ran a big personal fan pointed at the CPUs and the temp reading decreased from 86 deg down to 67 deg. I still was having the same symtoms as before. Usually a blue screen with error message in small white letters.... page_fault to invalid page etc. Then a reboot autmatically. I alwsays get spontaneous reboots with or without the blue screen messages. To go to 2.3 v, I'll need 8 more jumper plugs, I seem to be short. What does HSF & MBM5 stand for ? Rich Sias PS I have 2 memories, 256Meg, 8ns 124Mhz, and 7.5ns 133Mhz. Doubt if that were why I reboot trying to overclock to 100Mhz. |

I ran a big personal fan pointed at the CPUs and the temp reading decreased from 86 deg down to 67 deg. Degrees of 'what'? F? Unlikely you have CPU temps of 67F, unless you mean at pure dead idle, or suspend, with a boffo heatsink and a dern cold room. CASE temp I would believe. What motherboard are you running them on and what are you measuring this temperature with? I still was having the same symtoms as before.

I alwsays get spontaneous reboots with or without the blue screen messages. The reason it reboots on a blue screen, and 'spontaneously', is because you have "Automatically reboot" set in System Properties/Advanced - Startup and Recovery options. This, btw, is what causes the "it reboots when I try to shutdown" symptom that occasionally crops up: There's something wrong that causes an error during the shutdown process and 'recovery' faithfully logs it and then reboots the machine, as it is set to do.

Fan & Heatsink is GlobalWin, fooey can't read label - its spinning while I type - duh! anyway it is about 2" thick, just filling space between the slot1 adapter boards for the dual socktets.

Yes, and room is 62 or 61 now, its is starting to warm up again, now spring is approaching. (unheated basement). Normally 82 but with personal 6" fan on high blowing direct on CPUs I get 67 after 15 minutes at Idle. I d/l Prime 95 and ran some load test and it sat at 82 without the personal fan. Might drop to 70's with the fan on. Unlikely you have CPU temps of 67F, unless you mean at pure dead idle, or suspend, with a boffo heatsink and a dern cold room. CASE temp I would believe. What motherboard are you running them on and what are you measuring this temperature with? Shuttle HOT649a and sensors are MB mounted and lap up the slot1 socket up to the slot. Not real accurate on chip temp but gives something relevant, just off by some degrees and with some delay of detection. I still was having the same symtoms as before.

OK, now that I have played around here is what I found out. All attempting
to use 100Mhz FSB. 1. Setting RAS precharge to 2, I get --- "The procedure entry point SameEnumerateServicesDomain could not be located in teh dynamic link library." 2. Setting only RAS-CAS delay to 2 rather than 3. RAS prech = 3. pnp680.sys page fault in nonpaged memory. Win not start. 3. all items left for default (3s). Black screen and nothing forever. No errors no hits etc. I have an extra EIDE card called SYBA containing a Silicon Image 0680 chip. The pnp680.sys is 3/15/2002. Date on item d/l = 6/2002 probalby has copy from march. Looks like the HDW added 2 months ago is problem. Except I added these things then we are locked out untill later. Rich Sias |

Well, it's 'relevant' if you had some way of knowing what it means, but I can assure you it isn't anywhere even close to die temp. Overclocked Slot-1 celerons aren't easy to cool to begin with and it's doubly hard (pardon the pun) when on a dual motherboard because of the space and airflow limitations, plus needing to keep them under 50C (CPU metal lid temp) or so.

Pull the heatsinks, clean everything, and reinstall with fresh thermal compound. Then put in one processor, one memory stick (the PC133 probably), and a video card, nothing else, and work from there. Get that stable and then add the second processor. Then the second memory stick. Then whatever else. You ARE setting the PCI divider to 1/3 and AGP to 2/3 when setting the FSB to 100MHz, right? |

Which one of these is it? http://www.checkmate.gr/globalwin/cel_slot1.htm http://www.checkmate.gr/globalwin/cel_ppga.htm I guess it might be CPM25603-16 as both the fins are 1" and the fan is about 1" thick.

Well, I used to overclock these from 2000 until 2003 @105Mhz. I had a critical app for work to use and install worked better at 66Mhz so I left it there since last spring to be sure I had NO problems with it. Now that I am unemployed I want to return to what I used to have. I just can't recall the settings I used to have. The only change is an addition of a PCI IDE card. See notes in following messages.
