600 to 900 on a cuv4x

[Volrath]

i have a celeron 600 and im trying to push it to 900 on my asus cuv4x board
i can get it to 900 at 1.6v but its not as stable as i want it to be
so i tried upping the voltage to 1.7 and any voltage above 1.7 makes the machine lock COLD after it detects the hard drives and cd roms. Any idea why it will go 900 (unstable) at 1.6 and go nowhere at 1.7?
thx

Raising the voltage increase the temp. slightly.
Maybe just enough to cause you a problem.

ADDED This after reading next (correct) post by Mr B : Ooops!! The following paragraph is an excellent example of foot in mouth desease.

The default Voltage on a Celeron 600 is 1.7V. It really surprises me that you can even post at 1.6V. Have you got good memory installed? Adequate cooling? What temps are reported by the Hardware Monitoring Bios page?
I think if the temps reported by bios are under 40C (runs hotter while in Bios on my board) I would try bumping the voltage to 1.85 or 1.9 and set the memory to CAS 3, see if that will boot. If not try removing the CPU and heatsink/fan and reinstalling using good thermal paste (after cleaning the residue from previous installation with alcohol) and make double sure you have a good flat interface of the HSF with the CPU. Lapping the heatsink wouldn't hurt if you haven't already done so. See lapping instruction in the cooling section of Tips and Techniques available on the home page.
Good luck!

Hey Volrath,

Welcome to the forums!! Hope you like the place. Just don't get too used to it. We've got a brand new forums in the works that will blow this one away. Stick around and see !!

On to your Celeron....

Sounds like heat might be playing a role here, but I cannot be sure. I'd need to know a few more specifics about your system to pinpoint (or try to) the couse of your problem.

Most specifically, what are you using for a heatsink/fan on the C II ?? The intel piece won't cut it at 1.7v (I'm assuming where you say you've upped the voltage, you have one of the cB0 chips (1.5v default)) and high FSB settings. If you are using this, you really might want to look into better cooling. If you have your heart set on 950 or more, don't even bother with a Golden Orb (Gorb) cooler. You'll have the same results at those speeds as you have now (assuming you are using the intel hsf). Alpha, GlobalWin, and Swiftech make some really good hsf's.

Let us know a bit more about your system (cooling especially), and we can help out a lot more.

Thanks for correcting my error Mr B. >(
Volrath sorry 'bout that! Never take advice from a guy who not satisfied with 44C at full load, re-laps his heatsink, and now has 58C full load.(tonight, after giving forth pearls of wisdom) And welcome to the forum. ;D

i think that your problem is not only with the temps, but for the temps, you cuold bye a volcano 2 with a delta 38 cfm cooler, a some good fans for the system, the next thing to do is to go to the bios setup and in the chip setings reduce mem latency timer from 1.5 ns to 1ns, and reduce agp multiplier from 4x to 2x, thet should be enought.
