- Under-volting the AYHJA 1.33Ghz T-Bird -

[NokiaDude]

A little under a month ago I got my month old 1.33Ghz AYHJA T-Bird in the mail, I read on the forums and on the net that it has immense over-clocking possibilities with exotic cooling of course. Well with a huge Taisol copper plated heatsink I got for free, it will only do ~1.46Ghz, a 133mhz overclock without going haywire. But that was at default voltage, I heard waaay too many horror stories of T-Bird burning up when the voltage is pumped. So now I want to turn around and go backwards, under-clocking! So at the moment I typing with the T-Bird @ 1.33Ghz with the core voltage set to 1.6v in the bios but it read 1.63 with SpeedFan. If you have experience overclocking the 1.33Ghz T-Bird or have any advice for a nooB to overclocking please, leave a post!

I think you heard T-bred overvolting horror stories, the T-Bird is tough! I personally know of a 600@1ghz@2v for years now and still going. Pump that Vcore to 1.85v if your cooling is up to it and see what the clock speed maxs@stable. Probably won't get much more than 1.54ghz if so put it back where it's at since less than @100mhz isn't worth the extra heat and voltage.

Well I under-volted the T-Bird yesterday to 1.6v in the BIOS, but in XP Pro it says that the core voltage is 1.68v. Doesn't matter, it's running 5C cooler. NICE

Edit: Just as I was typing XP was acting kinda weird, so reset to CPU Default voltage. Stupid Abit over-volts the CPU, it says 1.75 in the BIOS but it reads 1.79 in XP Pro. Temps: (1.60)1.68v;45C Idle 50C Load / (1.75)1.79;49C Idle 55C Load.

How was Xp acting weird?? Try undervolting to 1.6v again and run prime95.

It was really unstable, the keyboard was typing letters that I didn't want to type and it was just , unstable. The only problem with this board is that it over-volts the CPU, i.e. I set it to 1.6v in BIOS it reads 1.69 in XP.

i nuked my ayhja 1333 tbird by overvolting it to 1.95 volts. it ran for a year at 1.85 volts tho, and i think i was able to hit 1550mhz.

I suppose you're using a Asus mobo?? It tends to do the overvolting bit. I've undervolted my AYHJA to 1.5v before and everything was alright.

Nope, Abit KT7A-RAID and an Antec SL300S 300w PSU. I'm getting the AT7-MAX2 soon.
