The most popular server motherboard on NewEgg, however, still only supports 32GB, only has 2 USB 2.0 ports, three gigabit network interfaces, a graphics chip the manufacturer doesn't seem to admit exists - which is okay, since it only supports SVGA output anyway, no sound card, only 2+1 power stages, has RAM compatibility issues, has issues with one of the LAN ports causing instability issues, lacks drivers for many OSes (incl Windows Server 2012, IIRC), has limited socket spacing (though does fit the stock Intel heatsink, which is a nice change), the SuperMicro website is horrible for finding the right drivers, has a finicky RAID solution, especially finicky when using SSDs apparently, etc... and costs $174

The top consumer pick, the AsRock Z77 Extreme4, has a 32GB RAM capacity, 2x USB2.0, 4xUSB3.0 (+front panel connections for both), DVI+HDMI+SVGA, optical audio + 7.1 analog audio, gigabit LAN, 6 PCI-e slots, fits into more cases, has 8+4 power phases, has fantastic RAM compatibility, has a fantastic layout, has a better warranty, etc.. and costs $144.

Now, if I was building a mission critical computer, I'd absolutely jump to ECC RAM, which limits my motherboard choices. If I absolutely needed to scale beyond 8 cores, then I'd obviously be limited... but beyond that, consumer boards are simply better.

Eh, I don't play with single socket re-brands. And all of my SuperMicro gear, put simply, just works. Granted none of it was ~$200, probably triple or more than that.

I don't need or want onboard audio or video. I also dont need extravagant VRM setups because overclocking isnt a thing on the platform.

The ram limitation on that board is CPU specific as well, its not a motherboard thing. And the 3x GbE ports are telling of its intended use.

Your signature systems are garbage, are they up to date? Your dual-CPU quad core Xeon system has the combined performance of a cheap i7 2600k (of course, you could have been running that since '07 thumb.gif).

That said, a good VRM setup is about stable voltages. A 2+1 config will have vDroop even without overclocking, though it should suffice for low-end systems.

The discussion, remember, was about what made the most sense for a normal computer build.

It could have been a veiled attack, a joke, or even serious. There's no way to know without indicators in the message, which are all absent.

I agree that sarcasm doesn't translate to text but you can feel it depending on the situation and also the guy who you reply to. If you don't, it's best to stay away.

lets just say, if i had Intel stock i would be selling it right now. and buying amd

If you had Intel stock and sold it for AMD stock, then you'd be a fool.

It would've only made a good trade off when people got AMD down at like $1.5 because they are up to $2.2 now.

the number of phases has nothing to do with voltage drop. The number of vrm phases is an efficiency thing. 1 phase- always on, 2 phase each phase is on 50% of the time etc.... In the case of computer parts they opt for more phases so they can use smaller more efficient designs, rather than having fewer larger amperage VRMs. The number of phases will also tend to be more power efficient due fact they can switch on and off as needed to supply the required amperage IE at idle the cpu can get by with only a single phase active at a time, under load it can vary the number of phases active.

All the bottlenecks and all the missed expectations. Tsk~

Personally, can't wait for Apple to sue both AMD/Jim Keller. Release the infringement AMD, do it!

It has everything to do with voltage drop transients with P-state and load transitions. Additional phases are more reliable as the load is spread to more hardware, the voltage output is more stable, and each phase can be built with cheaper components (since they handle less power).

If you want tight control, you need more phases, period. If you don't care about quality, you use fewer phases. Of course, you can make a high quality two phase VRM, and a low quality four phase VRM, but by the time you get to 8+4 DigiPower vs 2 phases of even a high quality, there's simply no comparison. Ripple, vdroop, vrise, mean time to failure, are all in favor of the consumer board.

Of course, if price is no object, and you don't care about performance, you end up buying a board with enough quality that it isn't a problem. And when CPUs are a very well defined quantity, and your using power conditioning, and high quality power supplies, and well controlled environments, it becomes much less of a concern.

Apple is a very sue-happy company, so you may get your wish simply because of the strikingly similar arrangement.
