Are 939 opterons Venus or sandiego cores??

[Plywood99]

Just as the title say, I thought 939 opties were of the venus core, but now I here they are rebranded Sandies, what is the real deal???

[Major]

San Diego cores, 1mb cache

[dogsx2]

They may be sd cores but they are not the same. They don't scale with Vcore like sd does. They are not rebranded sd's, that's for sure.

Venus = San Diego

[VVJ]

Venus = San Diego

Socket 939, CPUID=$20F71 - San Diego only.

[Petr]

They are all SH8-E4 cores. "San Diego" and "Venus" are not names of the cores but of processors!

[Apokalipse]

Venus = San Diego

yup, the only difference is that the San diego has more L2 cache

and the Opterons have a locked multi
all A64's can lower their multi, and FX's can also raise it.

I thought it was established that the opteron's will lower too, with that 5*multi shot. Also arent there some 2mb cache 939 opterons coming out?

Right. They can lower multi.

dont they have the same l2 cache (1m)?
and iirc u can change opterons' multiplier to lower value?

[Apokalipse]

well maybe they can, but that's just what I heard

[VVJ]

San Diego has the same L2 cache size as Venus. Venus is related to the Socket940 processors, not to Socket939.

[Hugo van Dijk]

So what is the Denmark core then (2mb l2 cache)

[Apokalipse]

San Diego has the same L2 cache size as Venus. Venus is related to the Socket940 processors, not to Socket939.

oh, so it is. I thought they were talking about the Venice, and just didn't spell it properly
*edit*
maybe some people did mean the Venice

they have 3 denmark 939 2meg opterons on there-170 range

No, Venus and San Diego = 1 Mb ... this is the same core with two name.
Also, the multi are not locked to down

[onewingedangel]

denmark is a dual core part with 2 x 1MB cache, not a single 2MB cache.

I believe the only thing that seperates venus and san diago are memory controllers and number of hypertransport links. The number of HT links is unimportant in uniprocessor configurations so thats no loss for the 1 series, but san diago uses non registered memory wheras venus needs registered, whether there is an architectural difference or some arbitrary locking mechanism I don't know, but the use of non registered memory in the 939 opterons means that the core is exactly the same as San Diago, but really AMD could call them whatever they wanted if they wanted to seperate the lines, intel do just that, and the xeons are exactly the same as the p4's.

might wanna fix this then

[Vapor]

I'm willing to say that these aren't San Diegos....very weird mem controller quirks and different voltage scaling being my reasons.

Why did you use an old build of 0525 (May 25)? Today is October! Maybe you should use the first beta of CBId 1.0?

[i found nemo]

no the name of the processors is a64, then what ever the pr rating is, unless you have sempron or opteron then pr rating does not apply then you have 146 or 144 or so on so forth sandiego is the code name

I agree, they just don't scale the same with voltage.

San Diego cores, 1mb cache

I'm sorry guys didn't mean to start a debate over cores, I actually read the post so quickly to begin with that I thought he was asking if the cores were Veince or San Diego. Really just thought he wanted to know how much cache they had onboard.

i take it you have it fixed already then?
when i get my rig up and running again, i'll take another shot for you
