are the 939 opterons comparable to the s940 opterons?

any advantages/disadvantages for either one?

the 940's can have 2 cpu's, right? does that mean you can overclock both CPUs?

thanks in advance for any help

940's can use ECC RAM and can run in multiple CPU systems.

939's use cheaper parts, so if it's only a single cpu, it's better.

Slight correction here...s940 MUST use ECC Ram, s939 MAY use it.
s939 MAY use cheaper parts, but doesn't need to...
s939 is for single processor systems only, s940 can use as many as 8, but will be expanding to 32 this quarter on the Horus chipset (each of those processors may also be dual core).
In general, the s940 is for server/workstation systems whcih are never overclocked...

I thought is must use Registered memory too? Either way, you don't want s940 unless you are going to run it in certain server/workstation environments.

is it possible to OC them though? also, would an opteron that's s939 perform pretty much equally to the one for a 940? or is one better than the other?

As far as gaming goes, socket 940 would suck, because of the high latency of ECC ram.

I don't know if a socket940 MoBo would have any overclocking features, since 940 is designed for maximum stability (hence ECC ram) rather than max performance.

thanks rod. wait, so high latency ram is bad for games? so when choosing ram, higher clock speeds should be priority over latency? thanks a lot rod

harsh, but right on

High latency ram is bad for everything.... think about it, how can high lag be good? I'd take higher clock speeds over anything though! If you want to overclock get a socket 939, if you want to start a server and you have big bucks get socket 940. But socket 940 is a waste for gaming.

when i asked if "higher clock speeds should be priority over latency?" i meant if "higher clock speeds should be priority over lower latency?"

i don't have big bucks...i have like $700 for the whole system lol. i was just asking about this cause i wanted to know if i came across cheap s940 parts, should i get them or not. but you clearly answered my questions (all of you) and thank you for your help
