DFI's NF590 and RD580 AM2 Motherboards

With 95% of DFI's shipments being AMD platforms, it's not surprising that the two motherboards we are taking a look at are both AM2 platforms

DFI's nForce 590 SLI and CrossFire 3200 motherboards are both what you would expect from DFI, the most unique feature being the digital VRM design used on both motherboards. The digital VRM cleans up the layout around the CPU socket and eliminates the possibility of leaky capacitors. The added peace of mind comes at a higher total motherboard cost of course.

Note the lack of any conventional electrolytic capacitors around the CPU socket.

    Unfortunately due to changes in the VRM requirements for Conroe, no current LGA-775 motherboards will work with the new processor.

    Riiiiiiiiiiiiiiiiiight. I thought the next gen Intel chips are supposed to consume less power? I admit that I'm ignorant when it comes to such things, but the common sense tells me that VRM which supports TDP 130 should have no problem handling TDP 80? Could anyone elaborate?

    It happens every time Intel releases a new CPU. The then current chipset will support the CPU, but then the "VRM issue" pops up. It's a scam by Intel to force you to buy a new motherboard (preferrably with their chipset, of course). AMD doesn't seem to have this problem. Reply

    Yeah, slam that AM2 CPU into your old Socket 939 board. It will work! AMD doesn't require you to buy a new motherboard to buy their latest and greatest!

    Conroe is a huge departure from the P4. The fact that it works at all in LGA775 and with old chipsets is impressive.

    Bol(*#*&s, digitalfreak is right, of course this is a scam. Just because AMD is now using the same scam doesn't mean this is the way it has to be. I'm sure it wouldn't cost too many transistors to build in a legacy mode on the CPU die. Reply

    U guys are missing the point, the X2 dual core socket 939 cpu with TDP 89w works on the socket 939 motherboards that were available at launch 2 years ago, when .13µ newcastle cpus were the only game in town, barring any bios updates of course.

    Same thing for socket A, altho not at the right FSB speed depending on chipset.

    AMD only forces you to update if there is a significant feature difference that can't be worked out in the current socket. It seems that intel engineers its cpus without 'socket environment' consideration and then engineers a specific chipset for it, while amd engineers its cpus to fit in a specific socket environment that they defined a standard for long ago.

    So you don't think that lower power consumption due to the new VRM is a significant feature difference? It is all the technical press is talking about these days.

    The LGA775 socket was launched in June of 2004. So, here we are 2 years later with the same socket for Intel, but a change to the voltage regulator. And you can run dual core processors on what was originally a socket meant just for one core, just like AMD.

    Socket 939 was also launched 2 years ago, and it is already obsolete.

    Sounds like both companies have similar track records, as of late. Perhaps the march of technology these days simply will not allow for using the same motherboard for more than two years.

    It could be that the VRM requirements are for lower voltages or cleaner power or something along those lines. Also, just because Conroe runs cooler than Presler doesn't mean it can't have more stringent voltage requirements. I wouldn't be surprised if this is less of a case of *can't* run Conroe but more can't run 100% *stably*. The newer 975X chipsets/motherboards will probably have a few slight tweaks to fix some erratta encountered with current 975X designs. Reply

    Conroe has new power states that aren't supported by older motherboards. For example, a Conroe would try to go to "sleep" and the motherboard wouldn't supply the right level of power to it. Reply

    1 kilowatt power supply? bloody hell

    I like all the pictures. But I'm still waiting for Asus AM2 RD580.
