667 celeron..any tips?

[ramrod126]

I've got a 667 Celeron proc on an Asus CUV4x mobo. I have it running at 833 right now and have had it up to 950(unstable). I would really like to go for 1 gig(100mhz fsb) but I can't get it to post. I have pc 100 ram so That shouldn't be a problem. My hsf is homemade but it keeps my temp below 110 f at 833 w/1.75 core. Any tips from people who have gotten this proc to 1 gig would be helpful. If I can't get it there I will probably sell it and get a 700e Pentium if I can find one.

i cant give you any advise just to let you know Im in the same boat as you,
can only get it to run at 830. good luck anyway

[ramrod126]

E-mail me and we will compare notes.

i will when i get onto my other machine, this one doesnt have the letter that follows "o" and comes before "q" ....lol so I cant use my email correctly, frustrating really,

Well,I'v got a 667@950 with an Asus P3V4X,GORB,pc133 Micron and a V3 3000. I'v tried most everything i could to get this chip to 1 gig but i would say it will never get there,from what i'v read the chips with high mulitiplyers don't OC as well.The majority of people are only getting a 85mhz FSB with these 667,i guess i'm lucky to hit 95FSB.Anything over that and it won't post.Not what you want to hear,but probably your getting all that your going to get.I'm going to wait till I can get the P3 700e and see what I can do with that,but for now this chip does run really well.

Have you benchmarked yours at 950? I benched mine at 900 and it was slower than at 833!! I think it was because the pci bus is at 41 with 83 and only at 30 with 90.

I had same exact result with my new C667...upped voltage to 2.0V and voila! post and load win98 @1000mhz. After burn in hopefully be able to turn voltage down...

what where your settings before you ran it at 1gig and how long before you tried it at that seed???

[Ifish]

I tried 1 gig 15 minutes after I installed the CPU (I'm impatient) and it would not post until I reached 2.0V and it needed 2.05 to load windows. My mobo has no FSB setting between 83 and 100 mhz so as far as i'm concerned it's do or die at 1000 mhz. Chip is only 2 days old, we'll see what gives in a week or two

Hehe my 667 works perfectly at 1000mhz at 1.95 V very stable cBo stepping.

I'd personally sell the 667 and buy a 566 or 600 since they are the de rigeur celerons of our day for getting to 100Mhz FSB.

Think of it like this - how many people with Celeron 433's or 466's run at 100Mhz FSB............ And why don't they........ because the threshold of the Mendocino process is lower than their 100Mhz FSB speeds.


In the same way the Threshold of the Coppermine process is at about 950Mhz generally pre cC0 and even at cC0 in a lot of cases and as such even a 633 would be far too risky a chip to have a good chance of 100Mhz FSB.

I bet there's even some loon wondering why they can't do the business on a 766!!!!!!

God help us all.

1000 mhz at 1.85 volts here with the CCO stepping. I have not posted it in the database yet because I HATE taking my computer apart to get the numbers off the cpu (I should have thought about it before). This particular chip does not like going higher than a gigahertz. Higher than a gigahertz requires even more voltage and my heatsink (homemade YS tech 26 cfm fan mounted to a PC Club heavy duty heatsink, for those that have a BE6 ii, you know why I did this, not enough room for my Alpha) will probably not handle it. If you are running Windows ME, then you are already getting the benefits of a program like Rain 2.0. ME sends idling commands to the cpu just like Rain does in Windows 98. I personally believe that you should always use a cpu idling program if you are running an operating system that does not have it built in. Saves on electricity and runs the cpu cooler when heavy use is not needed. This is only the 2nd day on this setup. Previous setup, 566 to 850 Celeron II but it was the 1.5 volt aluminum interconnect version.

Update... I have now tested this cpu in 3d game applications. No lock ups or errors at all. No errors in Windows, no crashes during tests (Sandra and Wintune). I am very pleased. The copper stepping (CCO) has been well worth the wait. I had no idea what chip I was going to end up with, got lucky.

This is too wierd. I have nearly the exact same setup as you - a cCO 667 at 100 FSB / 1.85v. I also had a 566 at 850. This is like something out of the Twilight Zone.

[ramrod126]

Just an update.. I just orderd two 80mm Sunon case fans and a Fop38 hsf. I think heat is my prob so we will see what happens when I get these fans installed.

Any way you could ditch the 667 you now have (e-bay?) in favor of the same chip at cCO stepping? From what I have heard (and I have some personal experience to back it up) the cCO 667 is a lock at 1 GHz. Might be the best approach, but the P-III 700 sounds good too (though slightly more $$$).

Yep, the 566 would run 850 at 1.65 volts, but took a higher voltage to get to 935 which I did not normally run because I did not want to run my cd burner at non standard pci bus speeds. With the 667, even a small increase in bus speed over 100 requires at least .10 increase in voltage. It looks like1000 is the max on this particular chip. Even though I had no intention of running it higher than 100 fsb, I had to play around and see if it would go any higher. I can get it to boot in to Windows at higher speeds (around 1030) but I am a stability buff and it is just not stable at those speeds. I am not a heavy gamer, but like an occasional 3d game. 1050 might be possible with max 2.0 volts and better cooling, but my pci devices will not be happy and I would be borderline on stability. Ther e is nothing like standard bus speeds for stability. I always shoot for standard bus speeds now.

I have the 667 CC0 stepping chip, just got it set up yesterday. It does 833 out of the box with standard voltage. Solid as a rock running rc-5 prime95 no troubles so far. I have to use the wire trick on it since this mobo doesnt support voltage changes. I'm nervous about the wire thing but I'm sure this chip will go 1gig with proper voltage. Wont post on stock voltage. (big surprise there eh?)

Hi!,
Im now in the same boat I was in a while back. I have a cely 633, and about 2 weeks ago, could run STABLE at 950 for a very long time. I am now in the same prediciment as i was before, i cant get the darn thing to post at 950! I dont know what the bottleneck is...its not heat, i know this,(runs buetifully at 80C..when it runs:), could it be voltage?...what about ram...i have a weird setting of ram now, i just bought pc133 256mb stick..and i had 2x64mb pc 100's sticks...so i have all three slots filled...can this do it? any help would be appreciated!

[martialcomp]

It is almost certainly the ram configuration. Either go with the 1 256meg stick or the 2 64 meg sticks.
