View Full Version : Cel 1.10GHz, alphapep66
Alright-
Through a stroke of luck, i've just gotten my greasy fingers wrapped around a boxed Celeron 1.10GHz chip. It came with a fan. I am, of course, looking to o/c this baby- how good is the fan that came with this thing? I have an AlphaPEP66 here, still under the terms of the return agreement. Should I ship the Alpha back in favor of the Intel sink/fan, or is it far superior, allowing me to reach greater stable speeds? What do you think I would be able to hit with either?
Also, I'd like suggestions on what method I should take to o/c this chip to its maximum stable speed.
Specs:
576MB RAM (2x256, 1x64) PC 133
GeForce 256 32mb agp
Kensington NIC 10/100
SB PCI 128
BH6 board
realmagic dvd decoder
pci parallel card
--less important--
6x dvd (samsung) 32x cdread
16x12x40 yamaha cdr
20 GB WD 7200
60 GB WD 7200
floppy, of course
TIA,
Scathe
PS-Why is it that its damn near impossible to find a slotted motherboard as opposed to a socketed one these days?!
I say use the Alpha PEP66 with some good thermal paste and forget the factory Intel cooler. That model Alpha is a great slotket cooler. An overclock of 112 FSB would be a good goal and should yield about 1.23 gig. They don't make many slot one motherboards anymore because Intel quit making the slot one processors some time ago.
Alpha is obviously the best Slot coolers..
How could you even hesitate putting the Alpha in? especially if you actually have it!!!!!! :D
The Alpha is always a wiser choice over a retail fan!

The fan you got, is just the fan off of a 1.0 GHz PIII, or 933. Definately stick with the alpha.

Any specs on the fan? IS the fan really small? hehe
Alright, I decided to "store" the Intel cooling and attach the Alpha. The socket clip was a little tough, but it was fairly straightforward.
I entered the bios and set her for 112MHz, core voltage 1.75, with a multiplier, if you care about that, to 3.5.
The system booted with the chip running at 1.232GHz, then gave me some kind of error. Oops, forgot to disable speed check ;)
After that was corrected, the system booted to Windows (98SE) and displayed my background image. I had perhaps 5 seconds of device input before Windows went unstable on me. So now I'm running 100MHz, and the chip is running at its normal 1.1GHz. Which means it isn't overclocked worth squat. Heh. Suggestions welcome. For my system stats, check my first post.

Hi Scathe, welcome to the Forum,
Try rising the Vcore around 1.8-1.85v, to satisfy the increased request of energy of the Cpu OCed, and if still not stable try to set into the Bios the most conservative mem settings.
Remember to use a program to monitor the system/Cpu temps, I suggest MotherBoardMonitor, that you can found at http://mbm.livewiredev.com/ and never the Cpu temp must go above 45 degree C @full load (100% load), but less is better, to gain a rock stable OC.
I hope it helps you ;)
If you used crappy heat tape/pad that usually come with those heatsinks, then reinstall it using a good thermal paste. You might need a couple case fans too. The multiplier is locked at 11X on your CPU, so don't try setting it at something else, because it either won't work or the motherboard will ignore it. You claimed to of set it at 3.5X112 which equals 392 MHz??? It really should be 11X112=1232 MHz. Do you have a FSB setting between 100 and 112? If so try it. What are your load CPU temps? Don't raise the voltage up until you have your cooling taken care of, heat is the enemy. Sounds like you're close to reaching that overclock, you just need a bit more cooling and a little more voltage to get it stable. Good luck.

It's not a heat issue. That thing should run 112FSB at default Voltages with the Intel crap heatsink. At least my cCO 800 does. The thing is that 1100Mhz is just the 'official' top speed for the entire coppermine line. In other words this CPU might already be a little 'topped out' so raising the core Voltage is all you can do to get to 112FSB, and with an Alpha on it that shouldn't be a problem. Just don't take it over 1.85Vc without decent thermal paste and extra case cooling...
Yea the air flow is really imporant I would suggest 2-4 120MM Case Fans..
Have an equal amount of case flow.. So have the same amount as intake and exhaust.
First off, thanks so much for all your help. It's appreciated.
There's no setting between 100MHz and 112. What about the Turbo frequency?
At 112, I ran the core voltage up to 1.85, and Windows booted almost all the way, but lost stability. Just for the hell of it, I jacked the damn thing to what appears to be the maximum, 1.95, figuring that if that worked, I'd just get additional cooling. Still no result. Actually, running at that voltage, the chip never got over 37 degrees C. Is there no way to push this chip above 1100?? lol.
Any help would be appreciated, as I'm out of ideas.

These chips do have limits, with no way to back off to say 110, 109 mhz bus, without awesome cooling, you might not actually be able to overclock with that board.
I would also say that your memory might be crapping out, is it set to CAS3? It may not run set to CAS2... does your board have interleaving? This could also cause system instability.

Is CAS2 faster ram .. and CAS3 stabler ram?

Just out of curiousity, what 60mm fan is on the Alpha? You may need the cooling power of a Delta 38--if there's a lesser fan on there now. Your ears won't thank you, but the Celly II will.

Bah the deltas aren't THAT loud and they make your computer sound like a vacuum dont ya like that :p

CAS2 is faster, but obviously the memory needs to support it... his may not.

Well, he has a 64MB stick of RAM mixed in there, don't be so sure 'bout that ;).
I always tell folks to use the CAS-3 RAM timing when they first start overclocking. Once they get the cooling sorted out and the system stable, then maybe try going to CAS-2 since it's slightly faster. No sense trying CAS-2 at first though until you get the system running stable.

Put much better.

good thing I didn't take you up on that bet, huh? :p
