Celeron II 600 cC0 on a Asus CUSL2-C

[Aveman]

Anyone have any idea why I can't get this chip to post at anything above 810 MHz? I have raised the voltage and tried speed higher and get nothing, BTW I am running 810 MHz at 1.7 V. I have an average cooler and it runs the chip around 40 C with arctic silver paste. I am going to get a better fan, but shouldn't it atleast post at 819 at 1.75-2.0V?

I had a Abit VH6-II before this and it would do the same thing only at 747.

It is 100% stable.

Could it be the ram or somthing?

By the way I only have a 230 Watt Power Supply, is that enough? Or do I need a 300 Watt power supply?I tried different ram, I just don't understand why it can be 100 % stable and not post 9 MHz more, one wierd thing is that I can only sometimes get it to 810 MHz with the jumperless bios, but when I use the dip switches it always works perfect at 810 MHz. Is there any way to increase the core voltage when using dip switches? And when I get a new cooling fan what is a recommended burn in voltage?

Sorry for all the questions I am fairly new to overclocking.

If you got a lot of cards, and drives in your box, then you might need a bigger supply. If you can afford it, then I would get a 450w P4 ready power supply, then if you ever decide to either go with a Tbird, or P4, you will be ready with that part, and you will never suspect your supply ain't enough again...I run an Alpha P3-125 slot one cooler, with two fans..and all this box has in it, is a sound card, vid, and modem, and 1hdd, 1cdrom, and I had a 300w, and put this 450w and saw my fan rotation speeds jump100-200 rpm, and my system is rock stable...and I can play games all day, and come out of the game, and my temps are under 30c for the cpu, so like I said, if you get a monster supply, then you won't have to look at that aspect for a while.
And you make a good point, a lot of people don't take their supply into consideration when they are having trouble clocking...I say upgrade the power sup, first.
It sure helped me out

Yes, I'd get a better PSU. But most Cellies I've seen tend to get hinky when run that hot. I would put some effort into getting temps down in 35c range. With my set-up I've never had temps exceed 36c and its solid at 994 MHz. Before I got my Delta, temp could get upwards of 40c and she'd get flaky.

Well I got a 300 Watt power supply, and I didn't change anything, I read that this board will always initially boots up at core voltage but run at the FSB specified, the only way to fix this is to use a thin wire and connect three pins at the bottom of the cpu. I did this and now It is running at 1.9V at initial boot (before the ram test) and you can go all the way to 2.2V which I won't try. I am burning it in a 900 MHz at 2.0V. It can go to 945 no problem. I am going to get a new case and a Global Win FOP-38. With a couple extra case fans and then go from there.

I only paid $20 cdn for this power supply so I might just use this to run the fans in the case and look into a higher grade power supply.

thanks for the help
