Celeron 800@1200 MHz!!!

[Mackan]

I have my celeron2 800 running at 1200 MHz right now! And it's perfectly stable! Voltage is 2.0V though. My celeron did run at 137 fsb at defaultvoltage, then I had to upper the voltage step by step to reach 150 fsb, (pc133 memory also running at 150!!)but now I am there! :) I am using the great asus cusl2-c mobo.

Idle temp is 35C, and full load is 48C. Yes, it's a bit high, but I am more concerned about the voltage. Will the celeron run at 2.0V without taking damage in the near future? Or should I run at 146 fsb and only use 1.80V which it's stable at? There's a big difference in voltage there, but the number 1200 MHz is really appealing so I had to try. :)

I use a alpha fcpal350-cooler. It's not as good as the pep66, but it does it job. Other than that, I use a simple extra 80mm chassifan blowing in air.

Man, I'm still so excited and happy over reaching this 1200 MHz for a 90$ cpu. :) I wanted to stay Intel, and I am very happy so far. Haven't had a single problem using win2k, intel 815EP chipset cusl2-c mobo, and my 384 meg mosel vitel pc133 ram. Games run like a dream compared to my old system with a p3 450.. hehe.

Please comment on the cpu-voltage, is it dangerous or have people been using it on celerons for a longer period without damage caused?

Wow, very nice...

Do you know what the stepping on that CPU is? I want to find out if its a cD0 :)

As for the voltage, thats high, but since I'm not using a celly2 I have to 'no comment' here. Someone will reply.

It's a cCO. There are no cD0 celeron 800's afaik, but I think that celeron 850 and 900 may have cD0-stepping available. :)

[nucro]

Yes 2.0V is much but 1200 is like a dream

There are cD0 celeron 800s. There are cD0 celerons down to 733.

That's great! Mine's a cCO and the max. I've booted up with was 1120Mhz...

wow, you have beat the theoretical barrier of 1.13ghz, but at 2V that is certainly possible. Got some benchies and some screenshots? I am condering buying this cpu.

Nice overclock, congrats, you have every right to be proud. But yes, in my humble opinion, 2.0v with your cooling setup is probably too much for long term useage, especially considering the high temps. Why not do what I do. Do a few more cooling mods for safety's sake and then for those times when you feel the need for extreme overclocking, zoom up to top speed. For routine day to day stuff, back off a little. If you look at my signature, I have my top stable accomplishment listed. Yes, it's also at 2/0v, but I've got better cooling and CPU load temps rarely exceed 40 degrees. But no way do I run at that speed all the time. Normal cruising speed on my rig is 1050 MHz at 1.85v. When playing 3D games that I want max effort, I go with 1071 @ 1.9v. To be honest, I rarely run at my posted top stable speed. Actually, I've considered dropping the speed back down in my signature, because it might give newbie forum members the wrong idea that I use that speed all the time and that it's ok to run at 2.0v. What do others think? Comments?

[Lancelot]

Well battboy, I just constantly change my signature as I change my speed. So the speed you see in my signature is the speed I posted at. My situation is kind of the same as yours. My chip will run stable at 1080Mhz but with 1.95Vc and 3.6Vio, so for daily use I backed it down to 896Mhz (112 with 1/3PCI) at first, but the high PCI/IDE speed was causing some glitches when I burned audio-CD's. So now I'm at 1Ghz (125 with 1/4 PCI)and maybe I'll just sit at this speed from now on cuz the iBX chipset can handle 2x AGP uptil 125Mhz (where I am currently) and my RAM still runs at CAS-222, and my voltages are pretty low.

I would like to give you a screen, but it seems I have to upload it to a http-webpage first. Can't it just load from my harddrive?

Some updates: my max temp is actually 44C at 1200MHz now, I tried to run it later in the night when temps in my room was around 20C instead of 30C like it's in the day. (very hot in sweden right now) And my idle temp is 33-34C then. But then again, I have to use 2.0V and I dont like it.

I can run fsb 133 (=1066MHz) easily at defaultvoltage. Idle temp is then 30C, and max load is 40C. But for now I run it at fsb 140(=1120MHz) at 1.75V. Memory is set to work at cas2, so this machine is really fast now. :)

My asusboard disables agp4x and some memorytimings when I go higher then 140 fsb. It's the same on all new asusboards I think. But there's a tweaked bios allowing me to still run agp4x and maintain fastest memorytimings. I plan to flash it today. Then I can run it at 146 or 147 fsb and have the voltage 1.8-1.85V.

I am pretty surprised that my pc133 memory can handle 150 fsb. But it just keeps going, I even tried to boot up at 1208 Mhz, played some games, (mainly UT) and it succeeded without problems, but higher than that and windows upstart freezed, yet a sign of more voltage needed. But my mobo can only give 2.0V max.

Btw, why is the cpu-database empty?

Oh yes, I checked the intel support site. Now they have cD0 celerons as you said Zuyck Guo, but they must have added that recently because 2 weeks ago there were no cD0's. :)

Theoretical barrier ? I've been past the 1.13 marker with a 600 cC0 long before now along with many other people.
