A 336Celly @551 Getting Random Reboots, HELP

[SpeeDj]

Anyone got any ideas the vcore is currently running @ 2.2 Volts, had no problem with this at 495, increased the rame to PC133 Cas 2 and it ran fine for three weeks @ 551 Now I get random reboots. Sitting on the web and blink black screen reboot. Just wondering if perhaps I am doing something wrong. It was running just fine @ 2.17 Vcore. Just really confused if you need more info let me know. It has a Thermaltake golden orb on it, and the temp never gets above 54C runs between 37-54C Anyone with any kind of help please let me know.

Had the same problem myself. I have a Cel2-600 and i had it at 900. No problem with lockups or CPU heat but the same problem you have. After running SiSoft Sandra I found out that since my CPU originally was a 66Mhz the AGP divider was set to 1/1, which means my GeForce was running at 100Mhz instead of 66. My mobo had a jumper to manually set the AGP to 2/3 and now it works. Seems the autodetect just focus on the original CPU fsb speed. Try setting AGP divider to 2/3.

Note: It took about a week before it started rebooting so I think I´m on the right track here.

Sounds like a heat prob...and I can't get my cpu to do anything above 38c...when it reaches 37c I start to worry, I also think that intel's temp recomendations are unrealistic.
maybe it's ok for stock proc's but extreemely clocked cpu's will start crashing above 37-38c
I have a freind with a cBo 800e, and his crashes at 38c...try to get some more cooling, maybe your answer is to simply open the case to let more air in...worked for me :-)

Funny you should mention cooling I am currently working on getting a Waterblock and Radiator I finally decided to build a water cooled rig the other day. I settled on the enclosed home depot Junction box design. So I bought an submersible pump, 213 GPh From Petworld it's made by a company called Maxi Jet and let me tell you it was a steal at 22$ Anyone know anything about these lemme know. That will be my next attempt at cooling or I was looking at that Peltec Site and found their cooling solutions to be intriguing =) Thanks for the help!

I do have two 80 MM Case fans as well as a fan on my vid card. Maybe they just aren't pushing enough air ? This is all in a full tower box by the way. Anyone know of a great full tower case for cheap ? Thinking of building a dual Celly system anyone have any recommendations ? =)

Thanks for the AGP Divider advice I will check that out, and does anyone know if a Voodoo banshee doesn't like to be overclocked ? =)
