Celeron 1200@1600= no go :( soooo sad

It's weird.. cuz I can make it POST @ 1600 if I use the 3:3:1 divider. But it is a no go with the 4:4:1 divider which should be more stable.
I'm using an abit st6 mobo and I did the wire trick but it makes no difference.

Anyone got any tips for me?? plz!! I HAVE to get this chip up 2 1600!!!!!!!!!!!!!!!!!
 
tips?

Yes. Use the 'search' function here to access a mountain of information. There are several members who posted a lot of their experience with this. . . and it appears it is not easy but possible.

Some of the more serious O/C'ers needed to remove the heat spreader and cran k up the voltage more than just with the wire trick.
 
I did a search. But I couldn't find any useful info. CRAAPppppppp.. Just want someone to tell me what's wrong since I can't run this mobo with the 4:4:1 divider!
 
Did you try the archives?

Much of what was posted used keywords like "Tualatin".

How far are you able to O/C stable?
 
122 mhz is stable with the 3:3:1 divider. I also tried 133 mhz bus and I got a post with the 3:3:1 divider but that is as far as I got.
My soundcard (sblive) isn't stable even at 122 mhz bus. So I am currently running this cpu at default speed.

According to the manual the mainboard (abit ST6) is capable of using the 4:4:1 divider from bussped of 97 mhz and up. I've tried it several times at busspeeds from 100 to 133 mhz. It seems to work only randomly! Only two times did it boot with the 4:4:1 divider.

I tried it with 122 mhz bus just now.. works nicely with 3:3:1 divider (except my soundcard doesn't work) and I changed the divider to 4:4:1 and I can't even make it POST!! Something must be wrong, right?!?

I also tried setting the FSB manually with jumpers but then all I could get was a 64 mhz busspeed when it was sposed to be 133 mhz bus!

Any clues?

No I didn't try the archives but I will now. Thanx.
 
you need to realize that very few tualerons can make it to 1.6 - that is why people tend to favor the 1.0A and 1.1 - i would bet you are sh!t out of luck unless you can get big voltage to the chip and then you risk smoking it.

no offense, but people need to throttle back sometimes and think about what they are shooting for. best case scenario w/ the 1.2 is 12x133 or maybe a bit more if you are REALLY lucky, a 1.0A at 140 w/ ram at 140 will blow doors on the 1.2 @ 1.6 in 99% of real world usage. so in the end what was the point in buying the more expensive & less overclockable chip? just some food for thought.
 
Plestor is right. 1.2 @ 1.6 is pretty tough. I always recommend 1.0A instead. Most C1.2's wind up ~ 125 FSB, 1.5 GHz. If you want to get to 1.6, you will have to do more work. Try Overclockers.com. Maybe ol' man can help you out. He lives and breaths this setup and knows the ST6 very well.
 
Thanks Mr. Fart and others. I know it was stupid of me to go for the 1200.. But I had such luck with celerons earlier. I've had a 300@450, 600@900 and 733@1100.

When the 300A's came I bought seven of them (boxed) and ALL of them made it to 450 with boxed fan and not too high voltage. So I sold them as 450's and earned a few bucks 🙂

I know the 1200 is a completely different story. I might try to exchange my 1200 for an 1100A at the local store. maybe give them a few bucks between.. Hopefully they will agree, but prolly not.

I'm thinking if I can't get rid of this chip maybe I could use it for my divx/vcdplayer/musicmachine in my livingroom.. Should run very cool @ 800 mhz, maybe I could manage with only a good heatsink, my 733 almost did at 733.
 
I finally got my 1.0A running at 140, some things to try: unplug all extra cd-rw, dvd and hdds, set all memory settings to slowest (ie cas3, all other settings on slow... remove any pci cards (apart from network card they dont matter) , do the vid mod, get a decent cooler and keep trying stuff... find the highest stable freq and do a burn in to get more... maybe you will be able to get closer. Many of the 1.2s have been going at 129, 130,131 fsb. Good Luck~!
 
I got my Celemine Celeron 800 to 1066, but I don't want to go higher. 🙂

I am selling the system soon to a person who does not know much about computers but wants to learn more. So it needs to somewhat stable 🙂

I know its got more head room, its ideal temp at 1066 is about 29 C.
