I would expect that to pass smoke test, then, incorrectly installed as in not full speed rather than upside down or something, I'm actually surprised that it didn't show up working on POST and only be obvious with the cover off or using dmidecode. Or whatever the Windows tool is to get the same information. I would have expected it to boot, too, but it didn't. I tried to boot before opening the machine. It's been long enough that I don't remember if it got past a power-on POST and stopped at a blank screen. Maybe that would have constituted passing a smoke test. I can understand why a tester in a hurry wouldn't want to wait for Vista to boot. Since I intended to add memory, I didn't hesitate to take the cover off to see what was going on. Making what I thought would be a correct memory install fixed the problem. Glad you like it, I have been thinking of a 930 for a KVM server, drop in 12GB of RAM and 4TB of cheap disk and put all the boring little 512m servers on Earth on it. |

Everything now goes through this 64-bit Windows desktop, including a virtual 64-bit Fedora 13 and a virtual 32-bit Windows XP Professional, with a Cygwin X-server handling graphical output from other Linux boxes. The virtualized machines, both Windows and Linux running simultaneously, are at least as snappy as Windows and Linux running on E8200 and E8400 Core 2 Duo. I wish someone made affordable 4Gb DDR3 non-ECC, since memory is the only thing that is ever remotely in short supply. The virtualized XP Professional will allow me to decommission a separate box running XP just to support a handful of legacy XP programs. Robert. |

That's one of the reasons I'm looking at an i7-930 and Asus m/b for a hosting system, I can get to 12GB with cheap memory. On the other hand, the i7-875 unlocked is cheap and allows o/c by use of multiplier. But no cheap memory there, need 4GB parts. I'm tempted to build a host machine with Xeons and ECC memory, slightly more reliable and all, but I think slower. Lots of ways to go, each with a drawback. :-( |

When the chip had just come out, I saw a geek buying the parts to build a computer for a chess competition. Who else buys machines with these chips? I can use the memory bandwidth, but, for most, the triple channel arrangement is overkill. All you really want is the extra memory slots. Just glad to have it, wish 4GB sticks weren't so expensive.

It's relative, Newegg has a sale on three channel memory, ddr3 1600, 12GB/$500. I can remember not having 12GB of disk, so that's not all that expensive. They have the i7-930 and Asus board for $500 also, TB drives for $68, I paid millions for that kind of capacity "back when." ;-) But the memory isn't that crazy, I was thinking that for $1k I could move from one old core2-6600 w/ 4GB to enough to make the VMs dance a little faster. |

I haven't gushed about a chip since the 130nm Tualatin. Mostly, I've wondered why the chip couldn't deliver what I expected. Core i7-920 is an exception. Virtualization works well enough so that, except for Linux and the sound card, I don't notice that I'm using a virtual machine, which is noticeably faster than a 3GHz Pentium 4 for Linux. Windows XP on Windows Vista even makes the sound card transparent. I'm using all vmware, so I don't know how other solutions might work. I haven't yet succeeded in overloading it. I'll admit, I've become so cynical about computers and software that just seeing a gnome-terminal pop when I ask for it seems like a miracle, never mind that it's on a virtual box. Admittedly, the core 2 duo E8xx almost seem like overkill for a single user, but I haven't tried to virtualize anything on them (yet). Robert. |
