Socket 939 A64/Opteron

The Opteron is AMDs server and workstation processor, it is based off the Athlon 64 processor. Originally opterons only came in Skt 940, however AMD has introduced 939 and am2 opterons along with Socket F opterons which is the replacement socket for 940.

[edit]

Socket F (1207) Opteron

Require registered DDR2.
Can be used in multiprocessor configurations. (2000 series up to 2 processors, 8000 series upto 8 processors)
Stock speeds range from 1.8ghz to 2.8ghz.

[edit]

Socket AM2 Opteron

Codenamed Santa Ana
Feature 2x1MB cache compared to the 2x512kb cache on the other AM2 athlon X2s.
Stock speeds range from 1.8gh to 2.8ghz.
Use standard DDR2.

Socket 940 Opteron

Can be used in multiprocessor configurations. (200 series up to 2 processors, 800 upto 8 processors)
Requires registered ram. (aka ECC RAM)
Lack of Skt 940 motherboards.
Sledgehammer Core, Troy Core and Athens Core are used for single core, socket 940 Opterons.

[edit]

Socket 939 Opteron (UP)

Can be used in almost all standard Socket 939 motherboards. (although this may not be officially supported).
Single-core Opterons are based on the San Diego core as found in the FX57, but in Opterons it's called Venus.
Locked multiplier.
Very good overclocker (except for the CABGE stepping which was merely average). 2.8-3ghz has been reported frequently although as always this is not guaranteed.
At the moment there is a shortage of these processors.
3.6ghz has been reached using the 146 on a modded mach1 phasechange systems.
Socket 939 Dual-core Opterons use the Denmark Core which is for all purposes a Toledo Core.

Stepping Info:

CABNE 0539 and before were great overclockers ~3.0ghz+
CABNE 0540 and after havnt been that great but still not bad ~2.8ghz
CABYE 0539 and before not to bad ~2.8ghz
CABYE 0540 and after great oc'ers ~3.0ghz+
CABGE All weeks not the greatest 2.6-2.7 at high voltage
CAB2E All weeks are hitting about 3.0ghz+ except the 0546 FPDW, which has never been seen above 2.8ghz, even at 1.6v.
CACJE from 2006 have also been doing pretty well, 2.9ghz+ on relatively low voltage and air cooling.
CAB1E 0614 and anything else that happens to come out, 2.9+ stock/low voltage
