The following Emails from users are all we know right now on the Blue Durons. It does not look like they overclock any better than greens – we have many Duron 700s hitting 1 GHz+. The only difference in codes I can find is that either “A” or “B” follows the week #; I have two greens that show “E”. Unless we see Blue Durons hitting consistent 1100 – 1200 MHz, I don’t think color means too much.
“Perhaps it’s old news, but I’ve never seen a single line talking about blue Durons on your site. And an “old” article (17/08) was saying that all the Durons are green. A friend of mine has bought one last Saturday. Since I’ve told him that he would only find green ones, he was surprised (and me too). The numbers:
L1 bridges are intact. Now he’s waiting for the KT7 he ordered at the same time. My question : are these chips really “copper-made”?

“Just read your site again about copper Durons. If you say the coding is true, my 600 had blue sealant and had the code of this on the chip:
Also something strange my core has no green or blue shine to it!!!!!!
Just the blue sealant around the core!
“I have one, I bought it at the computer show in san Francisco, Ca, and running it at 1009 MHz.
“I am a 15 year old overclocker from Sydney, my rig is a K6-300 @366 @2.7v. I have bought a Duron 700 and not sure what color it is.
It appears to be a purple (it deepens the way you look at it, sometimes silver, or metallic blue); hope to get something decent out of it with a watercooler in production (doesn’t matter how long it takes, waiting for a DDR mobo and the $’s anyway). Got it for AU225$ which is about US$128. It is sweet to know that this one looks promising with the L1 intact (and I have one). Anyway the s/n is:
“I have a blue Duron (week 28) imported from Australia to New Zealand, and my friend has one also, bought in New Zealand a week ago. We have both been able to overclock our chips; I make 992 MHz stable, 1013 with cold water cooling (about 6C/42.8F) and he made 1001 MHz unstable, but is running stable at 980 MHz. We are using Golden Orbs.
