Identifying via the box

Identifying via the board

System builder motherboard information
So many revisions, few compatible with Core 2 Duo

DailyTech has come across an Intel presentation detailing how to identify Core 2 Duo Conroe supporting Intel D975XBX Bad Axe motherboards. Intel’s D975XBX Bad Axe was originally released towards the end of 2005 in conjunction with the launch of the Pentium D 9xx series Presler processors. The board offered support for ATI’s CrossFire technology via two PCI Express x16 slots that had eight PCI-E lanes running to each slot. At the time it was publicly known Intel’s upcoming Core 2 Duo would be supported by Intel’s 975X Express chipset. It was unknown which motherboards would support Core 2 Duo since Core 2 Duo uses lower power and manufacturers would need to integrate the proper VRM. Intel wasn’t one of those manufacturers.

Only later revisions of the Intel D975XBX Bad Axe support Core 2 Duo processors. To identify if a board supports Core 2 Duo or not users will have to find the AA number on the motherboard or box. The AA number is located above the DIMM slots on motherboards and on top of the box. Motherboards with AA numbers that end in -304 or higher officially support upcoming Core 2 Duo Conroe processors. Revision -304 is the newest revision that was revised on March 17th, 2006. The new revision adds ten resistors and two capacitors to the existing D975XBX design and updates the BIOS to version 0618.

Intel is expected to announce a D975XBX2 motherboard later this year, at least according to Intel roadmaps. However, even though the motherboards have slightly different specifications, footnotes in the launch roadmaps seem to indicate the boards are more-or-less the same.

All Intel D975XBX motherboards retailers received after April 16th, 2006 should properly support Core 2 Duo Conroe processors. Other motherboard manufacturers such as ASUS, Epox, Gigabyte, MSI and Universal Abit are expected to produce Core 2 Duo compatible motherboards based on Intel’s 975X Express, P965 Broadwater, NVIDIA’s nForce 590 SLI and ATI’s RD600.

Old news.

Guys on [H] forums talked about 304 well before X-bit.

Who cares? DT just found out about it today, as did I.

Already documented in the Intel ECN for Bad Axe

This was CLEARLY detailed in an ECN (engineering change notice) for the board, published by Intel.

There is no need for any further story or comment, because there is no new information.

However, for certain Bad Axe boards which are NOT the new compliant ones, some users have been able to perform a mod by adding a few components so that their boards are demonstrated to ALSO work with Conroe chips.

anyone know what mfg or part no for cpu cooler used in the 2nd photo? Looks like thermoelectric/peltier.

Its an Intel developed watercooling module, the pump is integrated into the waterblock itself while the fan and radiator are attached to a cases 120mm exhaust.
It was shown on the booth at CeBIT under 'Extreme Gaming' with a Pentium Extreme Edition running at 4.5GHz but if you asked them nicely they'd knock it up to 5GHz :)

CPU Cooler

nice. like the clean and simple design. 5GHz seems like it performs quiet well. thanks for the info.

oh that cooler is intel's own water cooling kit. no one knows when it will come out, and prolly no one care. B/c every w/c kit out there can beat that.

The REAL problem is finding a retailer / e-tailer who positively has 304 'boards in stock, AND isn't asking an arm and a leg, which translates to as much as $270 USD + taxes.

I think the problem come the end of July isn't going to be buying a boxed Conroe, it's going to be buying a Conroe ready 'board. Just imagine, the fastest CPU available and no 'board to run it in.

Many retailers have them -- they just don't want to cannabalize their older board sales by giving that info up.

They can either sell a new board, or sell no board at all. People are almost frothing at the mouth to buy a '304 board, and yet none appear to be found. People are not going to buy a 302 or 303 board, they simply won'y buy anything.

advice please...

i know this isn't the right forum for this but i thought i'd give it a shot anyways... should i wait till july 23 to get one of these conroes, or should i just get the cheap dual core that is on newegg right now for around 110$ cause my budget is around 160 or less, i'm not even sure how much these conroes will cost... i just need a really good cpu for multi-tasking (listening to music, surfing, photoshop, dvd burning etc...), not gaming, just curious if anyone could help me out, thanks

Personally, I say wait for further price drops. The Core 2 Duos aren't likely to be cheap, but they may come out with a $180 CPU. That was the P4 3.0 Gig's price for a long time. I can't say don't get a Pentium D, but with the stock cooler they can get loud with high CPU utilization, and 3rd party coolers add a lot more expense. But the P-D's ought to drop further in price. Mainly, get an upgradeable mobo since the Core 2 Duo may be set for a long lifespan.

Maybe it will have DDR2-800 support, since the new Asus 975X board claims that.
