January or Q2 ??
"released in Q2 (around the second week of January) 2006" -That doesn't sound right... When is it?

Has been reworded - Stordoff 13:54, 3 December 2005 (UTC)

Still doesn't make sense. January isn't in Q2 of 2006. Which is it? January or Q2? TomTheHand 04:58, 27 December 2005 (UTC)

Jan is in Q2 06 in the financial year. Q1 was last oct-dec 05.


 * If you're the US Government. If you're another government or a corporation it may be entirely different, and if you're a normal person, Q1 is January to March. TomTheHand 14:15, 10 January 2006 (UTC)

Pacifica Virtualisation Support
Does anybody know for sure that all AM2 processors support Pacifica? It could be added to the 90nm/SSE3 sentence if so... 71.116.217.242 19:56, 26 June 2006 (UTC)

DDR2's clock speed
It said DDR2 ran at higher clock speeds than DDr. This is not true. DDR2 usually runs at lower clock speeds than DDR, and it is technologically impossible to make DDR2 faster than DDR. The difference is that DDR2 can transfer twice as many bits per clock cycle. Minipie8 00:38, 1 October 2006 (UTC)


 * No, you are simply wrong. DDR 2 has gotten up to 1066 mhz and beyond, obviously DDR2 is faster. Also, the article says that DDR2 suffers from higher latencies than DDR 1 also, not true.


 * Latency is a inverse function of clock speed, so when you do the math, the latencies actually haven't risen at all, they just haven't dropped. —Preceding unsigned comment added by 71.159.16.144 (talk • contribs) 11:09, February 24, 2008


 * The actual clock driving the memory (the core frequency) has not changed nearly as much as you would imply; DDR2-1066 has the same core clock that DDR-533 would (AFAIK no such beast ever existed, although DDR-500 memory is still barely available). But DDR2-1066 is not what most people buy, even today; something more like DDR2-667 (which has the same core frequency as DDR-333) is more typical.


 * The bus speed has gone up quite a lot with DDR2, but only because DDR2 uses a 4-bit buffer instead of a 2-bit buffer. That additional buffering is why latencies for DDR2 are in fact significantly higher; latency is emphatically not just the inverse of the bus frequency.  Lost Circuits has an overview that includes a discussion of the increased latencies.  DDR2 (like DDR3 and, in fact, DDR) is about trading worse latencies for more bandwidth. —  Aluvus  t/c 01:19, 25 February 2008 (UTC)

Socket AM2+
Should I add some info about Socket AM2+ in this article or start a new article? -210.0.209.178 06:05, 8 November 2006 (UTC)

AM2 is a great port to CPUs and I have a AMD Athlon 64 at 2.01 GHz, Way to go, AMD!

Presido
I believe that the German Wikipedia says that the Presido security features are present in the AM2 socket processors. This should be added to the article, as well as a separate Presido article in the English Wikipedia, once this can be verified. 198.82.59.102 01:19, 6 February 2007 (UTC)


 * That's supposed to be Presidio, not Presido. 71.254.86.63 02:29, 26 May 2007 (UTC)

AMD Processors
AMD Has gone a long way and they have done great since they stopped cloning old Intel CPUs. Turions and Athlon 64s, I think are the best ones —The preceding unsigned comment was added by 207.47.167.30 (talk) 20:33, 25 February 2007 (UTC).

Socket AM3
"AMD has announced that Socket AM3 processors will be able to run on Socket AM2 motherboards, but not vice-versa (that is a Socket AM2 chip cannot run on a Socket AM3 motherboard)." ... "Since AM2 processors lack the new memory controller as well as the HyperTransport, they will work on AM3 motherboards, but with functions as same as plugging in a socket AM2 motherboard."

Am I crazy, or is the article contradicting itself? -Roma_emu 00:36, 4 March 2007 (UTC)

More on AM3 compatibility
There is some debate going on over in the Socket AM3 discussion tab about how compatible the new Socket AM3 based Athlon II and Phenom II processors are with pre-AM3 motherboards. User Ham Pastrami suggested that the Socket AM3 page wasn't the proper forum to document such issues, and s/he has a valid point.

So, we have some issues here. We need a reference on the AM3 page that points back to a legacy compatibility section here on the AM2 page, as well on the AM2+ page, so that we can clearly point readers to the proper article(s). That will stop the cross-article contamination issue over on the AM3 page.

Next, we need to further document the scope of compatibility between AM3 processors (and also AM2+ processors) with AM2 motherboards. We know that AMD announced that AM3 processors should work with AM2 motherboards. But, to what extent? Did AMD alter the voltage requirements of the AM3 to levels that are uncommon for AM2 boards? Even if an AM3 (or AM2+) processor meets the TDP of an AM2 motherboard, are there other thermal considerations that need to be met? Are the majority of AM2 boards meeting the physical requirements, only to be abandoned by their manufacturers who refuse to update their BIOS profiles because they deem the boards too old?

There's not a lot of current documentation out there that I was able to find. There are a few recent motherboard user forum posts that document successful trials of AM3 processors on classic AM2 motherboards, even without official BIOS support, but nothing comprehensive to date. Most of the articles related to the subject are regarding AM2+ processors on AM2 motherboards. Even they are very light on details. Dinjiin (talk) 21:29, 21 September 2009 (UTC)

Opteron
the Opteron article currently says some Opteron can run on AM2. Thus not only Athlon and Sempron like Socket AM2 says. Tobias Conradi (Talk) 17:50, 24 April 2007 (UTC)

Phenom Quad on AM2?
Will AMD Phenom processors be able to run on AM2 sockets? --Mecanismo | Talk 23:54, 22 July 2007 (UTC)
 * As of the current information available then yes but a Bios update is needed. --Denniss 00:17, 23 July 2007 (UTC)

The BIOS can deliberately disable a CPU it doesn't recognize, but other than that, no explicit BIOS support is required.97.125.85.79 (talk) 00:11, 4 June 2009 (UTC)

list of Supported chipset
I am starting a new section with a list of supported chipsets. It is far from complete because I couldn't find anywhere a proper list of available chipsets for each socket/cpu. AugustinMa (talk) 16:39, 20 November 2007 (UTC)
