View Full Version : Need help with cel800- haven't overclocked in years
Yes, yes, go ahead and laugh. I have *forgotten*everything I ever knew about overclocking. I work as a systems technician full time, and a freelance consultant on the side, and so i haven't had any calling for overclocking. The last job I did was on a pair of twin systems that I did with a friend. They were both BH6, Cel533. We were able to get his up to 866, but mine only goes up to 707 no matter what I do. Well, now, I'm annoyed, and would like to break the GHz barrier.
We just got some cel800s in at work, and the obvious thought came to mind: bypassing the $100 it would cost to buy a cel1.2 and oc the 800 to 1GHz+. Only problem is, I don't friggin know how anymore. Can I get some help? Is this even possible?
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
No problem. Of course you have to use a slotket adapter. For this level of overclocking, I recommend getting a better CPU cooler and forgetting about the Intel retail heatsink and fan. Next, do not use the heat tape that often comes with the CPU coolers. Invest in a good thermal paste. To actually overclock, go into the BIOS, disable speed error check, go into "user define" and set the FSB up to a faster speed. Check temps and test for stability. If you're not stable, make sure you're not overheating and bump up CPU core voltage a notch. Good luck.

Welcome to OCers.com :D
So (out of curiousity)which BH6 ya got ?? I love my old BX boards.

Look at my siggy, I'm there but it took some work. Get a decent HSF and use thermal paste. Then set the AGP speed to 1x and Aperture to 4MB (you can raise this later on). If you get a cDO chip it must be easy to reach 133FSB. Let us know what happens, ok?!
I always forget what specific board I have. I have the original Golden Orb fan on my processor currently, with a decent supply of silver whatever thermal paste on hand. Should cool up to 1.13GHz approximately, even though it was released in 98. this baby was made to last. Thanks for the help

Well, what kinda fsb options ya got in bios ??
(and I'd lose the Gorb)
Is that a Cel 533 or 533a. If your slotket is old enough, it may not support the newer Cellies.
Those Golden Orbs were good back in the days of running a Celeron 566 up to 850, but there are coolers out now that are so much better. I would not use a Golden Orb for 1 gig or above overclocking.
It's an 'a', I believe. Why get rid of it? It's rated for 1.13.
If everyone says I should go up, then I will. I'll just have to figure out a way to quiet the sucker down. ;)
You guys are more current on the subject than I could hope to be at this interval, and $20-40 is still a savings vs. the $100 I would have had to have spent on the 1.2GHz chip.

Hmmm....
The BH6 only supports to 700mhz doesn't it?
... About the GoldenOrb... It will support up to 1.12gig but at 1.12 gig the Gorb isn't going to be as effective...
I would suggest an Alpha Dual fan one .. Those are sweet!

from what ive heard if your using a slocket the Alpha Pep66 is the way to go......the Alpah dual fan P3125 is pretty nice, but its only or slot one....
Those BH6 boards will support all coppermine CPUs if you use a good slotket. I agree with FunnyDude, can't go wrong with the Alpha PEP66 CPU cooler. Golden Orbs rated for 1.13 gig? That's quite a stretch. Trust us, the Gorb sucks for modern overclocking.

I have a Celeron 850@1206mhz (1133mhz right now). My Celeron can run up to 1227mhz at 1.95v. I don't run it that high right now because I don't have good cooling. I do have a BH6 rev 1.2, and an asus smart slot, and have had no problems running the cpu way over 1 gigahert. It is VERY fast. And the Celeron cDo cores seem to do over 1gig no problem. My chip does 1133mhz@1.60v! and it is stable. To run any higher I need to up the voltage a lot. to go to 1200mhz and over I have to use 1.90v.. But the Celeron 800's should overclock just as good!
Slick.
What's a dangerous temperature to look out for while my other fan is out on order?
Perhaps I should buy a probe?
Also, is acoustical padding foam a good material to quiet down my system?
Thanks again,
Scathe
As for an overclocked coppermine CPU load temp, they often start showing signs of instability in the mid-40's, but probably don't get into the "danger zone" until 50 degrees or more. Personally, for good stability and safety, I like keeping my CPU at 40 degrees or less when I'm overclocking. Non-overclocked CPUs at default voltages seem to handle higher temps better. Generally, it's the combination of both high voltage and heat that will lead to damaging a CPU.
Alright, the PEP66 is on order. It looks like a sweet HSF.. thanks for the recommendations. So, when I get it, how high and with what method do you think I'd be able to push the sucker?

Here is what I'd do with a new C-800. Install the CPU into the socket and lock her down, use Arctic Silver thermal paste instead of the thermal pad or tape that will come with the Alpha cooler, install the cooler, set everything at default settings, crank it up, and check temps. If everything is working ok, I'd pump up the FSB to 112 MHz just to see how it was doing. Test for stability and monitor temps. If everything goes great, I might next try going straight for 133 FSB. This would give you an overclock of 1064 MHz and should have the PCI and AGP buses still running in spec. Test for stability and check temps again. Bump up the voltage one notch if you have stability problems and if the temps are still ok. From there, you're on your own. If your system runs ok at that speed and the voltage and temps are not too high, then you might wish to push it higher, if you so choose. If you luck out and have a cD0 CPU that overclocks easily at 133 FSB, then I'm guessing with proper cooling and if you're using good components, you probably ought to be able to reach at least 1.1 to 1.2 gig. Good luck.

Very good advice! The PEP66(T) comes with a small bag of silver colored thermal paste, not any 'frag' tape of some sort. Alpha is not stupid!

hehe course Alpha is not stoopid rofl..!
My Alpha PAL that I bought last spring came with a stick on thermal pad. Glad to see they are now using paste.
