Anyone know anything about socket 940 Opterons?
I have a vague idea that it preceded the 939 but am wondering if people still use this socket and if it was used in this country.

Cheers,
Zeph.
 
Socket 940 is for Enterprise solutions mainly. Found in servers and the like. There were a couple of A64 CPUs on this socket but was quickly usurped by Socket 939.

Socket AM2 will also use 940 but the pin-out is slightly different and won't be backward compatable. (The plastic mechanism is new too on current early builds so anyone upgrading to this socket will be looking to upgrade their HSF too).
 
As above

The original Opterons were released on Socket 940. The 200 and 800 series Opterons (for multi-CPU applications) are still Socket 940. The original Athlon 64 FX chips were rebadged Opterons and were also released on Socket 940 (FX-51 and FX-53)

The Opteron 100 series for Socket 940 was discontinued and migrated to Socket 939, primarily to reduce costs for entry level servers and workstations. The motherboards for Socket 940 were more expensive and the memory required by Socket 940 (ECC Registered) is very expensive (£160 for one 1GB DIMM)

I'm currently running a Socket 940 Opteron system, purchased about this time last year (well before the Socket 939 Opterons were available). I went for the Opteron platform as it offered 1MB cache on the cheaper models and that it is easy to clock it to FX-51 speeds (2.2Ghz from the 2Ghz stock for my Opteron 146). Basically I had a cheap FX-51 system
 
I use S940. 2 x Opteron 250's. Placed in a Tyan K8WE. Although its large and expensive, its well worth it. Also given that AMD have just released a 285 2.6 64bit dual core monster cpu, makes this the power socket. But for how long?
