T-Bird 750 flying at 1050...some info about picking t-bird for oc..

[sleepdragon]

I was at Oakland Computer Show in Bay Area today, and Spoted a few
blue looking T-Bird 750 with code AHEA...T-Bird 750 are actually pretty cheap now...I picked 1 up for $160 after tax...and it's week 24...I believe it's copper t-bird...anyway...got back home and did the pencil trick to connect the L1 Bridge...and right now I am running at 1050/1.85v/fop32/asus a7v...for $160..it's a steal...

anyway...if anyone here is planning to pick up a t-bird and oc it..
this might be helpful...

Two words for picking a tbird that can overclock:

Blue Core

 

[neddog]

WHat exactly is supposed to be blue? The small square piece on the top of the processor?

NeDDoG

 

[? (=Þ)]

Yea, the metal slug, or core of the cpu. A blue (i think its blue...) tint means its from XXXXX production factory and should be a .18micron tbird, rather than a .25 micron tbird.

 

[neddog]

Do the green ones overclock too? Or should a person even bother trying?

NeDDoG

 

[? (=Þ)]

Yes they do, but i think the smaller die gives the blue tinted ones a base advantage in overclocking potential.

There are no 0,25micron t/birds, they all are 0,18. Difference is that those with blue core have copper interlevings(speling?)

"Yea, the metal slug, or core of the cpu. A blue (i think its blue...) tint means its from XXXXX production factory and should be a .18micron tbird, rather than a .25 micron tbird. "

It means the core was fabbed in the Dresden fab and thus has copper interconnects.

Anywho I own a 700 T-Bird with a blue core and it will not even do 850.

It is week 22.

At this point in the game I doubt the difference between copper and non copper makes a differnece in the overclockability.
Actually I would lean to say the green one are much better since they are not using a new technology and instead are using the tried and proven silicon interconnects.

Merle451,

You sure your T-Bird is copper?? what's the stepping code of it??
B/C I believe the copper T-Bird only found on T-Bird 750 and faster..
also, Copper T-Bird is much better to o/c...as matter of fact..if you
check overclocker.com's cpu database..you will see almost non of the green
T-Bird actually o/c above 950...and almost every blue one can reach 1gb..

also, if green is good enough..why aren't there any t-bird 1gb or 1.1gb
that are green?? all the t-bird above speed of 1gb are blue...go figure..

btw...sometimes thermal paste will turn the cpu die into purple color which is really close to the blue color...i know..b/c my duron is partially blue looking now..

I bought the AMD Thunderbird 900mhz about 3 weeks ago. I think it was a week 31 Thunderbird with the green core. With the Coolermaster HSF I was running 42­°C idle! I replaced the Coolermaster with the Alpha PAL-6035. Best $30 I ever spent as I'm now at 1.05Ghz at default 1.75v. Idle temp is 34-35°C. Everything runs stable. Now the only thing I'm missing is the raid hdd's and mushkin rev2. memory..HEHe

Are you cracking RC5 for the TEAM ANANDTECH? Your Thunderbirds and Durons at any speed would be a welcome addition!
