OC problems T-Bird 1000 ** Problem Solved ** THANX

[CyberConan]

I´m being unable to overclock my T-Bird 1GHz. No matter what configuration I choose, the system doesn´t boot.
I own a ABIT KT7A-RAID motherboard (it was suppossed to be one of the best OC mobo´s...)
My T-Bird is default clocked at 100MHz FSB, 10x multiplier, but any increase in FSB freq makes the system not to boot (of course I lower the multiplier accordingly).
I´m not sure what the problem is, maybe the SDRAM module? It´s a Green Memory Module (I know, it´s not the best, but it´s all I can get here in Argentina)

Any sugestion will be greatly apreciated.-

**UPDATE**

Finally I have unlocked my AXHA Thunderbird 1000, using conductive silver paint and a needle. It was very easy (I thought it would be more difficult due to the very small size of those bridges).
Now my chip is running very well @ 1000 MHz (133FSB 7.5x)
I´ll play a bit to see how far it goes... my only concern is temperature, at idle is about 40°C (25°C ambient)

Thanks everybody.-

did you unlock the multiplier on the chip?

 

[CyberConan]

I didn´t touch anything on the chip... maybe I didn´t understand very well this overclocking stuff... I thought it wasn´t necessary to change anything on chip since new mobo´s and their BIOS would do the trick !!

well there's your problem, Cyber Conan.

You have to unlock the multiplier on the chip by connecting the L1 bridges somehow, either by electr-conductive pen, a standard mechanical pencil with lead (you just draw the lines between the L1 bridges) or by a rear-window defogger kit.

It's fairly easy to do, but before you set about doing it, please refer to this article about doing so (and be sure to use a good heatsink and fan unit, I recommend either a GlobalWin fop-32 [quiet version] or a ThermoEngine with a 7k fan (loud)

Thanks, I´ll have a look at that L1 bridges tonight !!
(I already have a GlobalWin FOP 32-1 fan/cooler)
I´ve been also reading some articles on the stuff, now everething looks clearer for me!!
I´ll post the results as soon as my system is working and stable

Damn after reading the reviews I don't know what to get. The Global win and vantec seem to be very very loud. Maybe I should go with a Super Orb?

There are several misnomers about the super-orbs:

1) They aren't all that quiet. The dual-fan setup is actually midrange-noise level

2) Their performance is mediocre, and barely adequate for higher end t-birds.
