Is overclocking the E6 Venice to 2.6 the primary benefit?

Does the E6 Venice overclock more successfully?

You're right not a very thorough response.. was hoping someone else would jump insince this has been beaten to death.


here it goes:)

Basically the Opteron 148, 3500, and 3700 are the same price around $200.

These opterons are cherry picked, low tolerance chips, picked by AMD to run with lower volts in high temp envrioments perfectly stable for enterprise consumers. This means if you're intereted in overclocking they do very well. 2.8Ghz is quite normal on default voltage and 3Ghz with a little extra volts.

The opteron also has 512Kb more cache than the 3500, so it's faster clock for clock.

The opteron and 3700 perform the same stock, since they essentially same chip, but the Opteron 148 will/should clock higher.

As far as E6 seems the same as E3 top end wise - but memory controller is better.. offical DDR500 support - so if you buy a low clocked chip like say a 3000 and clock it sky high it should go a bit higher on the FSB/HTT than an E3. E4 which is opteron and 3700 have the same mem controller as E6.

The 1 meg cache in AMD chips is as fast latency-wise as the 512k in AMD chips?

That sounds interesting. I didn't realize it was Socket 939.

Can you elaborate on "essentially same chip"?

I am confused. Are you saying the E4 Venus and San Diego have the same memory controller as the E6 Venice? And that the E4 Venice is different than that one?

Is there an elegant obvious reason the words Venice and Venus as used here are similar?

There isnt a E4 venice it's called a san diego or venus and yes same mem controlelr as E6 venice.

I mean essential the same as in Amd calls one San Deigo core one Venus core but they are both same chip.

"The 1 meg cache in AMD chips is as fast latency-wise as the 512k in AMD chips? "

Good question i don't know.. I don't see why not though.. the 1MB chips are the premier line-up for AMD..can't see them crippling them from thier mainstream products like E3's and E6's

I am wary of the answers you've given.

There is an E4 Venice. EDIT: My mistake, it is E3.

There is a reason to consider whether the 1024k on a
chip is as fast as 512k on the otherwise same chip.

I guess the mentions of Opteron 148 mean the
San Diego would be the better buy.

I worry about the compatibility of the Opteron.
First sign of trouble and every person I talk to
will be screaming I shouldn't run a server
processor in a desktop machine, even if it
does have aspirations as a workstation.

Do they make an ECC capable Opteron with
the "essentially the same chip" as Venus?

If I am going Opteron I may as well make a
somewhat legitimate workstation with it...

Do some more homework

Venice = E3, E6
San Diego =E4
Opteron = E4

If you find an E4 Venice post a link here, and I eat crow:)

And as to the latency of the 1mb, all I can tell you is I upgraded from a 512mb chip to the 1mb San Diego, and the SD wins all benches at the same clock speed. As Zebo said, I don't think this would be possible if the 1mb cache was at a lower latency

I would'nt worry about that but overclocking you mentioned instead if you're buildiing these for people.

Cynical much?

Get a decent mobo thats proven to work with s939 opterons, problem solved

Do they make an ECC capable Opteron with
the "essentially the same chip" as Venus?
??? Don't understand the question, all chips AMD makes on the 90nm process are essentially the same chips Venice,SD,Manchester,Toledo, and all the opteron cores,ect....
ECC ram is only supported on the socket 940 motherboards, not on s939 mobos

If I am going Opteron I may as well make a
somewhat legitimate workstation with it...

Yes, I mixed up E3 and E4. I corrected the mistake and tagged
it as such 5 minutes before GuitarDaddy's "homework" jab.

I will not be seeking re-election.

If the machine if for yourself, i'd go with the Opteron, easy choice.

If it's for someone else, i'd get the 3700+ SD.

I don't know N, for anyone that is looking AMD should be going Opterons if they plan to OC even a little bit!

:D

If you want a Socket 939 Opteron (like the 148) you'd better hurry up and order one because once they're gone, they're gone! AMD isn't going to ship anymore to retailers.

That's just a rumor. I don't think it makes sense.

Anyway, if I want an Opteron, I'd get socket 940.
Unfortunately, there are no 90n socket 940 100s.

Yet there are socket 939. Perhaps AMD just wants
to get rid of them since they overlap with new 64s.

EDIT: I mean single core 100s. Not Denmark.
