The same capability apears to be built into the K8 memory controllers as well (see the K8 BIOS Programming Guide). Which is not that surprising really - the only electrical difference between registered and unbuffered DDR2 is a difference in the capacitive loading (ignoring the two address parity pins which would be ignored and unaffected by an unbuffered module anyhow). The only other difference is in the timings which are easily configurable.
The question then comes down to whether the motherboard manufacturers have done something in hardware to break this ability, or whether all that is required is a BIOS change to allow the board to start with unbuffered DIMMS and configure the CPU appropriately.
they are not going to use current s1207 boards for 4x4 for petes sake. why would they use a server board for enthusiasts. its going to be the same board as any enthusiast board, just with two processors and using s1207. im sure the chipset will be similar to the server boards, theyre probably going to use nforce pro, but thats where the similarities end.
A small detail to add is that most server boards don't aim at having SLI or Crossfire enabled. There are a few boards from each brand with high end workstation capability which have SLI capability but there aren't many. This is probably where the 4x4 scheme will have the biggest impact, will most likely require all the boards to have dual x16 PCI express and SLI/Crossfire support. One can probably expect the price of these mobos to be lower than that of server boards (which in general vary between 250$ and 500$ for dual sockets), all in all i think the 4x4 should be an attractive design for gamers and enthusiasts even with ECC ram.
I'm just going to throw this idea out to see if anyone might view this idea as reasonable.
AM2+ supports HTT 3.0 and the ability to split HTT lanes. Only a 8bit coherent HTT link is needed for 4x4
Thus AM2+ boards could support 4x4 and it is waiting for that change before such a setup happens. Just a thought.
yea nn step i wa wondering about that too what with the recent info beiing speculated at diff news sites across the web. what of this am2+ stuff etc. gos hi guess lots of thigns will be revealed come nov/dec
Ironically that is the eta for 4x4 :DQuote:

It is highly unlikely that random yield problems are the limit for the number of coherent hyperlinks on a given CPU.
Or in other words: if AMD wants to give AM2 CPUs a coherent hyperlink there is is nothing keeping them from doing so.
umm I believe we have already covered this.Quote:

I don't know whether you guys spotted that:

So, that FX is Socket F. Not some new socket happening to have 1207 pins, and not AM2. So it's straight server platform, and registered RAM.
somehow I question a technical site that has the phrase "* Mel Gibson * for President !"

Two FX-70 CPU pack matches pricing, clocks of Core 2 QC6700
By Theo Valich: Saturday 07 October 2006, 07:09
WITH THE IMMINENT launch of Core 2 QC6700 (codename: Kentsfield), AMD will respond by introducing the QuadFather platform, marketing dubbed the 4x4. The platform consists of Opteron workstation motherboards using Socket 1207 and equipped with two PCIe x16 slots for graphics cards and retail packaged CPUs.
We have learned that not many motherboard vendors will support the platform, so it is up to the highest-end manufacturers such as Tyan, SuperMicro, or Iwill to offer 4x4 motherboards. This will hardly differ from current 1207-pin-socketed Opteron motherboards. At the same time, it seems that AMD will finally remove the need for Registered ECC memory for Athlons, but another source is countering this info with the claim that FX-70 series will be nothing more but the Opterons and that the processors will require usage of Registered DIMM memory.
The retail boxes are coming in a bit larger size than current packaging and feature an open look at two CPUs, but for the first time, AMD will be launching not one, but three FX CPU packages. All of the CPUs will feature 256KB of L1 and 2MB of L2 cache memory (each core has 64+64KB L1 and 1MB L2 cache), and be placed in three speed grades.
FX-70 CPUs will be clocked at 2.6 GHz, with the price of $999 for a dual-processor retail box.
FX-72 will be clocked at 2.8 GHz, and with the price of $1132, it presents an interesting choice, since it outclocks Kentsfield.
FX-74 is clocked at 3.0 GHz and finally breaks the 3 GHz clock barrier for desktop and dual-core CPUs in general. However, the price is currently planned at sky-high $1500, so who ever spends that amount of money in the year of K8L (Barcelona) arrival, it should better have another $1,500 in the bank - for quad-core Barcelona babies, of course.
All in all, it seems that there isn't much sense for AMD to release QuadFather platform in Q4'06, but this was probably directed by marketing, which needs strong answer to Kentsfield. However AMD, are you guys too little, too late when it comes to enthusiasts, which you kept with your doors shut while everything was la-la in Opteron land? µ

Only dual CPU packages?
What if you damage one chip while putting it in?
That's the stupidist thing I heard today.
Prices are good, though. $1500 for two 3.0 dual-cores would be interesting - right now.

Here is the answer to a big question which has bothered many of our readers. Although 4x4 uses the Opteron processor socket "F", it will not use registered ECC memory. Athlon 64 FX-70/72/74 will ask for regular DDR2 memory modules, with Corsair, Geil and OCZ offering blazingly fast memory for the system. Corsair will get some preference in reviews due to the fact that it sports the so-called "Enhanced Performance Profile", also known as SLI Memory. This was co-developed by Corsair and Nvidia. However, there are now over five different memory manufacturers offering a combined total of 17 different memory kits.
So they actually made a whole new platform.
New CPUs, new chipsets and new motherboards, none of them are compatible with either AM2 or Socket F. At all. And CPUs sold in pairs so if you blow one up then what?
That's insane. I'm lucky I didn't buy their stock when I wanted to.

he launch line up was revealed here, but the pricing has been "re-constructed" severely downwards, with the fastest CPU pack now matching the price of Intel's Kentsfield.
So I'm expecting pair of FX-74 for under $1000USD :D
Wonder what prices will be on FX-70 and FX-72 CPU's.
Good for us
It's still S1207 and updated NF590 x2, so may by some bright person will manage to 'mod' Opteron and fit it in 4x4 mobo. Everything is possible. Remember Athlon XP was moddable to Athlon MP only connecting one bridge on CPU. I know that this time it will be much more complicated, but who knows??Quote:

It's basically you go to a computing event and go to Tyan's exhibit and say
You: "Dude i got 4x4"
Tyan rep: "Yea...you got crippled dual processor server that will be obsolete when AMD K8L Launches"
:p

I think you better check when Intel is releasing Kentsfield. AS for 4x4 it looks very interesting!Quote:

INTEL decided to paper launch its upcoming CPU, but the space between launch and availability isn't that long.
The company told the world+dog that reviews of Intel Core 2 Extreme Quad Core Processor QX6700 will hit the wires on November 2nd 6AM time in continental Europe. This long name is the official one that Intel picked for this dual core baby.
These CPUs will be available on the November 14th and this includes retail and etail for systems based on it.
The Xeon 5300 reviews should arrive on November the 14th UK time and available that day too.
