AXIA ?

[malignant]

What is AXIA and AVIA and why are they an advantage?

AXIA and AVIA are the designations of two batches of AMD processor chips that were produced. Apparently the OEM versions of these batches are of a little higher quality than the normal OEM versions, with a much better chance of getting a copper core than in other batches of OEM chips.

Still, the only way to ensure you get a chip with a copper core is to buy a retail box. Even if the AXIA and AVIA chips do have copper cores, they still failed to meet the standards for retail chips in some way.

well that was helpful...

In general AXIA and AVIA chips are desired
because they continually demonstrate better
overclocking than other batches.
e.g.
the avg overclock for an AXIA/AVIA chip @ 1Ghz
is about 1.4 to 1.46 Ghz
v.s. 1.1 - 1.2 Ghz for other batches

Also, anything over 1.2 Ghz these days is copper,
even OEM ones.

Intel Components, AMD Components... all made in Taiwan!

Yes, they do apparently overclock better, which precisely illustrates my point of them having the copper cores. Copper cores overclock better, and don't heat up as much.

As for all 1.2Ghz and up being copper, maybe I had an older one, but I had an 1.2 OEM show up in a crushed box, courrier's fault, and the chip was completely cracked in it. I figured I may as well crack it open a little more, who would know... the core was definately aluminum!

Besides that, if there was no difference in OEM and Retail chips beyond warranty, packaging and the HSF, why would only a few batches like AXIA and AVIA overclock well?

One other difference, when I got my replacement I went for a retail box, paying the difference... now I'm not about to break it open to verify what the core is, but I can tell you it came with the L1 bridges uncut, which is a definate bonus. I know other people who bought retail boxes and their L1 bridges were uncut as well. I also know that they can overclock their chips (I personally don't overclock) and are getting next to no increase in temperature on the CPU.

Even if the newer 1.2 Ghz and above chips all have copper cores, the retail ones are better, no doubt about it. You can get lucky of course and get a good OEM chip, especially if you look for the AXIA and AVIA batches, but it is largely luck of the draw.

Do you know what HSF they are using for that over clocking. Because my 1.2 axia goes from 41C to 51C (maxload
condition)when I overclock to anything over 1200mhz.
(I have a bizzard hsf).

I thought I was wrong once, but I was mistaken.

none of the chips have copper cores they just have copper interconecters in them all the chips that come form dersden have the copper interconecters on them

I bought a 1.2 Ghz OEM athlon and my L1 bridges were uncut too. So it's not just a retail box thing. Maybe the bridge cutting machine went down for a week or something =)

Dude, I work at fujitsu microelectronics and we make Flash and Dram devices on 8" silicon wafers, and we use pretty much the same process as used in Logic microprocessors, and the aluminum interconnects in an AMD chip would be about 2-5 micons thick,...about 1000th the thickness of a human hair,(too small to be seen by the human eye)The vast Majority of the actual chip core would be ILD(interlayer dialectric..SiliconOXIDE generally) which would appear greyish. So when you cracked your core there would have been NO way for you to tell if it was copper or not visually.

All 1.0 ghz chips come from dresden(which uses copper)except for a few rare well yielding lots from austin(but nothing over 1.2ghz I hear.

I know this because Fujitsu(GMD gresham manufacturing division, fujitsu's only american fab)is in close partnership with AMD in their FASL flash project.

PS: Im a Yield Enhancement Specialist, and play with a Scanning Electron Microscope all day w00t!

Myself I could care less if it is copper or aluminum. My 1.2ghz OEM T-Bird does 1.46ghz easily. Plus the L1 bridges where all connected which sure beats the pencil trick.
