XP - Everest Cache and Memory Bandwidth

In the top 2 screenshots we ran 2GB of DDR3 memory at DDR2 timings just to get an idea how memory speed scaling effects synthetic latency and bandwidth figures. Obviously, nobody will purchase DDR3 modules and run them at DDR2 speeds, but we do so here just to provide a comparison. Our screenshots show that DDR3 does not really begin to attain latency figures under 50ns until speeds of ~1600Mhz and a Cas latency of 6 are applied. The X38 chipset seems to provide best latency and memory bandwdith figures with a Performance Level (tRD) of 6 or 7. In turn, using a tRD of 6 or 7 limits us of memory speeds between 1600-1800Mhz. The best performance actually comes in around DDR1800 with Cas 7-7-7 timings with a tRD of 7 at 1N command rate. There is more than a monetary premium to pay on this kind of performance though - higher voltages to both the Northbridge and memory. If building a PC for long term use, then DDR31600 at 400FSB should be attainable with low voltages to all key areas of the board, ensuring lower chances of hardware failure.

This is not really true, as Firewire800 has been out for some time, and eSATA is still not widely available. As for the comment above yours, Firewire800 is used in many media applications, and won't likely be eliminated soon (digital camera backs come to mind). And this doesn't answer my proposition that for $350, Firewire800 rather than Firewire400 should have been included. Why bother with the slower interface when you are paying for a "premium" product?I am sure that some manufacturers will be happy to see Firewire800 die. Heck, I'm sure they'd be happy if there was never a Firewire400, and we all used USB 1.1. After all, it's cheaper by 2 or 3 bucks, and that's what matters to them. Meanwhile, despite claims of durability, eSATA is still a weak connector, which is why you will still see photographers taking shots tethered to a Firewire800 bus when they're on location for years to come, rather than a eSATA connection.
For $350, they can add Firewire800. Heck, the price is just shy of 1/3 of a fully assembled iMac that includes Firewire800. Just for the motherboard.

"Firewire800 has been out for some time, and eSATA is still not widely available"Yes it is widely available. It has been on nearly every high end and many mid range motherboards for over a year. Also, every major external drive maker has eSATA models... Not many fw800 at all.
I am not trying to flame you or anything, but firewire 800 isnt going to happen, not like fw400 did. At the time fw400 was the best interface. Now we have eSATA for hard drives and USB 3.0 coming in a year or two. FW800 is dead Jim.... its dead.

I still don't see any media-based hardware that has eSATA. Much more firewire on that front. In fact, besides Hard Drive enclosures, I have not seen anything at all with eSATA.And again, if it is dead, why bother putting FW400 in? I mean, might as well save the user $5 from their $350 and eliminate it. Or, give them FW800 like you should have.

I'd imagine it's there just so they can have a checkmark next to "Firewire" in the comparison sheets. The only Firewire device I have ever used is our microscope camera, which I believe was designed prior to USB 2.0.I wouldn't say the eSata connector is weak, but the lack of flexibility in the cables is an annoyance.

Ok, well I still haven't used a eSATA device. I have used an external SATA enclosure, as MOBO makers decided to start out with external SATA connectors and I've used a FW800 device that also has an eSATA port (Newer Technology ministack v3), but of course, the Mac it is attached to does not have eSATA. I'm happy they included it, though.The point still remains that at $350 they give you the old generation firewire instead of the new.

Are there any motherboards with fw800 built in (other than maybe MAC)? just curious.takumsawsherman - Tuesday, December 11, 2007 - link
OK, my post ended up as a reply to the wrong post. Sorry.retrospooty - Monday, December 10, 2007 - link
Yes, USB kb/mice work in dos mode via a bios setting. just enable it.Etern205 - Monday, December 10, 2007 - link
I'm taking about wireless. Are you talking about wireless or wired?If it's wired then yes you'll have enable usb support for DOS if you want to use it.

My Bluetooth keyboard works now, however when I first installed Ubuntu I had the BIOS setting disabled, and the keyboard never worked in GRUB thereafter. Was not until I reinstalled with the BIOS setting enabled that I got the keyboard working in GRUB.Works in the BIOS regardless of the setting.
