ADEA???

[Liquide]

Have anyone heard of ADEA stepping and how good it is??? I have a Tbird 800 with ADEA stepping and green core. How much can i o/c it.
Now i run at 972 mhz. Can i go higher???

ADEA. well, take AXIA. The X is way later in the alphabet than D, so I would say that yours is an early TBird, thus wont overclock well. Dont quote me on that, all I am saying is that ADEA is much older than the newer AXIA/AZIAs.

Green cores don't OC as well as the blue ones. And now the new ones are like purple and the newest are white?

The color indicates where a core has been produced, not how old it is. I have a red (or like purple) one from week 8 and a green/blue one from week 14. The green one is the better overclocker.

 

[RichieZ]

Speculation was that the green ones were from austin and therefore didn't have copper interconnects. The blue cores were supposed to be from dresden fab and had copper interconnects. Generally it was found that the blues were much better overlockers.

Mine might as well be blue - I can't tell. But I know that Dresden is much closer than Texas because I'm from Germany. That doesn't have to say anything though

My AFFA Athlon 850 can hit 1GHz (7.5x133) at 1.8V, 1015 at 1.825V (7x145) and would do 1050 if I were to go for 1050 (7x150)

Man, I need a SCSI card that is OC friendly

Demon-Xanth, your probably out of luck for that as SCSI cards are typically extremely sensitive to an overclocked PCI bus.

The ADEA stepping was one of the earliest steppings of the T-Bird, for it's time it was pretty decent but compared to newer steppings your unlikely to clock as far. You may be able to get a bit firther then 972MHz but likely not too much further.

And just for common knowledge, the myth of the blue cores meaning copper interconnects and from Dresden FAB whereas the other cores mean aluminum interconnects and were from the Austin fab has long since been proven beyond a doubt that this is FALSE. The color of the die indicates NOTHING about age OR where it is produces as has been stated, nor does it in any way reflect upon whether the core uses copper interconnects. The color of the die depends upon the die polish used at the particular fabrication plant when the processor was made, and AMD generally rotates polish on an almost weekly basis between it's fabrication plants.

The die color will in no way impact the processor, nor is it in any way a reflection of the quality of the core.
For the record ALL AMD Athlon "Thunderbird" processors operating at or above 1GHz rated frequency are from the Dresden fabrication plant and use copper interconnects. The Austin plant is providing Athlon's rated below 1GHz, and are producing all current Duron processors.

I hope this helps to clear up some of the rampant confusion regarding die colors.

Rand: I hear most Adaptec cards can take a 40MHz PCI, this one didn't like a 36MHz PCI. But it's so old it actually had EISA and VLB sister cards and was pulled from a P90.

 

[Rand]

Adaptec's line of SCSI cards is usually better at taking to an overclocked PCI bus then are most SCSI cards but that's still not exactly saying much as in my experience they tend to be okay at up to about 39-40MHz PCI bus, after that they tend to start having issues.

I'd be happy if SCSI cards could just make it a bit higher... like 41MHz PCI bus and I'd be perfectly satisfied. Unfortunately they tend not to do the 41MHz PCI bus speed which is one of the more often used out of spec PCI bus speeds.

My Tekram 390U3W is picky as hell about PCI speed, got erros at 36mhz pci

 

[gimps]

Core color means nothing if the clock speed is 1.2 or higher (I think?) they are all produced using copper interconnects.
