First Intel Quad Core Ready Desktop Mobo Spotted
MojoDog writes "Today Universal Abit launched their AW9D and
AW9D-MAX motherboards based on the Intel 975X chipset. There has been much
anticipation in the industry for this series and as far as looks go, these
boards are built to please. One interesting bullet point in the spec list
is that these boards are "Quad Core Ready", in line with a possible year-end
release of
Intel's Quad-Core Kentsfield CPU perhaps? Time will tell!"
Will that make the Mac Pro any cheaper? Or maybe a quad-core iMac a possibility?
I have a AB9 Pro Intel 965-based board here with a Core 2 Duo E6400, and I can't get it to boot half the time. I get an error code 8.7. on the motherboard's LCD, which means "Check CPU Core Voltage". When it does boot, I occasionally get an error or "Device Verify Failed" from the AHCI BIOS while identifying my hard drives.
The system is impressively fast when it actually boots and works, but those two issues make the motherboard very difficult to actually use.
Agreed, but bear in mind that a single-bit error doesn't have to crash your system (or an app). In fact, it usually won't, because the amount of "critical" memory is very small relative to the total amount of RAM installed. Instead it will silently corrupt data. This could result in a momentary glitch in what's shown on the screen; it could result in an app delivering nonsensical results; or, far worse, it could result in bad data being written to disk or an app delivering subtly wrong results. Since all modern operating systems use all memory in your box for something (cache, usually) pretty much every single-bit error is going to screw something up.
I work with many ECC-using servers and there are typically one to five single-bit errors per month. Even though I understand the reasons for it, I am kind of bewildered that ECC isn't more common on high-end desktop systems. The RAM costs ~15% more, but gamers, for instance, are already willing to pay 50% markups (or more) for a 1% performance bump (if that). You could even market it as overclocker-friendly: the error checking will tell you when you're overclocking too high, and the error correcting will help you when you're right on the edge. It could also allow overclockers to identify DIMMs which can't keep up without the laborious process of "pull out a stick, run memtest overnight; put stick back in, pull out a different one, run memtest overnight; etc." (Or the worse one when DIMM has to be installed in pairs. Then you get the joy of testing every combination.)
