Athlon 64 X2 4800 ... 2.4 or 2.5GHz??

[Danzilla]

Hello. I recently got a hold of an AMD Athlon 64 X2 4800+. I tried to check it's value on completed Ebay auctions only to run into something of a surprise. There seem to be two versions and they're widely different in value. Does anyone know, and willing to explain this to me, or point me in the right direction as to why one is worth so much more than the other?
One runs at 2.5GHz and goes for $30-$50 (ADO4800IAA5D0). Nothing surprising for a 4 year old CPU. The other (ADA4800DAA6CD), same apparent ID is actually 2.4GHz and can sell regularly anywhere from $130, to $150, up to even over $200?!?! What's going on with this?

The 2.5GHz is socket AM2, the 2.4 is socket 939. The reason the 2.4 goes for quite a bit is because there are more than a few people with decently capable 939 systems that might need a dual-core boost, yet AMD doesn't manufacture 939 CPUs anymore, hence the lucrative used market.

Well that was fast. Thanks, that would explain it. Some people are always reluctant to get a whole new system if any decent upgrades are available. I remember a similar situation with the P4 3.06/533 northwoods (with hyperthreading!! (oooh!). I wanted one for a long while as the best available for my dell 8250, but the prices just never came down enough to make them worthwhile.

There were Socket AM2 4800+ X2's at the same s939 specs. That is, 2x 1MB L2 Cache and 2.4ghz clockspeed. They didn't last long at all since AMD ended up having to give huge price drops not long after the AM2 socket came about.

But as someone else already mentioned the 'CD' code at the end is Socket 939 and there is a huge premium on them since for the longest time they were in the $600 range and thus very few people bought them. Its even getting harder to find the 2x512KB L2 cache s939 cpu's. I have a couple, they are commanding a bigger premium compared to the socket am2 variants. I should probably sell them since they aren't doing anything but sitting in a drawer.

Cash them in ASAP while dual-cores are still not obsolete yet. Once they are s939 X2s will be as worthless as P4s and single-core A64s like today.
