NEED HELP, black screen as I OC an Duron 750! What is safe Duron temp? What ought to be limit on voltage on CPU and I/O?

[hovenas]

I want to oc a duron 750 and doing it by upping the FSB to 133mhz.
The Bios agrees but Win98SE won't start. It reverts to safetycopy, i.e like it was as I fresh installed it but with all the extras non-working.

What do I need to consider with the equip I've got? Could the Graphics card have any saying? Is there a way to determine the AGP bus speed with my motherboard?
Any valuable insights?

Eagerly anticipating samples from your collected wisdom...

Anyone?

Increase the core voltage.. max 1.85v is safe but keep a eye on the temperature and be sure too cool it good !!
I/O voltage has little or no effect on overclocking only use this when you're having problems with your video card.
I have a Duron700 that will do 7.5x133 but then prime95 is starting to give errors so i had to backup to 957

Thanx, what temp is safe for the duron? Mine runs at 45-50 something.

Depends on your MB because each mb reads temps differently. For a kt7 series board, 55-60C is usually the max.

Hi,

I've just stress tested my Duron a bit And i'm now 101% stable at 966... 7x138Mhz.
My core voltage is at 1.8v, I'm currently running, while i'm typing this:

- Unreal Tournament in window
- Prime
- Sisoft sandra
- Via hardware monitor
- IE 5.0

And it is completely stable. prime95 doesn't show any error at all !!
My temp is 46c core and 33c system temp. I'm very happy with this setup !

Sure sounds awesome! I'll try and get mine to do something beautiful tomorrow

Whizzy,

one thing, your cpu "temp" isn't cpu core temp.

Mike,

So i read your article.. but my conclusion (can be wrong) is that even with the 46c readout i get from the hardware monitor i still shouldn't worry to much ?!:frown:

Thanks !

 

[Mikewarrior2]

absolutely, your temps are fine.. just letting ya know that they aren't core temps.

Thanks for all the input. I think I have to remove the chip, whenever I try to change the multiplier, the screen dies on me and the computer won't do anything useful for 10 minutes. Is that typical if the bridges haven't been connected properly? I used conductive ink and did (what I believe) a pretty good job.

If you guys are out there, I redid the ink-job and now run at 7*133=933. Temp running UT is around 52. Voltage 1,8 I/O 3,7. Thanx for all help.
