OK, so what's in a colour

[Hammo]

Hi. Today I purchased two AMD XP1800 cpu's, from the one source. When I got back home and checked them out I found one has a brown coloured die and the other is green. Both are assembled in Malaysia with the same part numbers. Is there any difference between these chips? Cheers.

I think you mean packaging. One is a older packaging which is brown and AMD adapted a new organic type packaging which is green. The green CPUs are newer.

Both are based on the same architecture. The green CPU is newer since AMD started to use green pigment for the CPU after a while. That's all the difference.

I bet the green one is SMP locked as well. Check the L5 bridges and see if the one closest to the middle of the chip has a laser cut.

Thanks one and all. Took a chance and installed the green version. Don't know about SMP - what does that mean to me - no unlocking/overclocking? What I do know is that on the EPOX 8KHA+ board my XP 1700 was running at 43c yet with the A7V333 my XP1800 is running at around 57. Think the ASUS board reports the temp higher.

Or rather, the A7V333 is reading the internal diode, so the 8kha+ is reading too low.

Just cause it is a higher reading does not mean its inaccurate.

P.S. Again, more examples of why cross-motherboard temperature comparisons do not work at all
