Application Testing-
Our application results mimic the memory scores. At like settings, there are not any measurable differences between the chipsets. The slight latency advantage of the Premium board generates minor improvements in the benchmark results, something not noticed during actual system usage.
FSB Overclock Levels-
QX9650 11x410
QX9650 9x465
Our top screenshots show our initial results when pushing the CPU and memory to an 11x410 setting. The Premium board allowed us to set tRD at 5 and tRAS at 15 compared to 6 (using MemSet) and 18 on the Deluxe board. The Premium board defaulted to a tRD setting of 7 and the Deluxe to a default setting of 8 when utilizing the auto option. Other sub-timings were set slightly lower on the Premium board. The biggest difference between the two boards was the CPU and MCH voltage settings. The Premium board required 1.59375V for the CPU and 1.69V for the MCH while the Deluxe board required 1.64375V and 1.73V respectively. Whether these improvements are due to the BIOS or MCH improvements is up for debate currently. Based on preliminary results with other processors, we think it is a combination of both at this time.
Our bottom screenshot shows the maximum FSB rate we have reached with this particular CPU on the Premium board. Our results on the Deluxe board are almost identical down to the latency score. We are currently testing additional processors and will provide those results in the full review. It appears at this time that our selection of processors all reach the same FSB limits on either board. However, the voltages required and the memory settings allowed all show a slight advantage to the X48 equipped Premium board.

Ah, you are correct. G45 will be the GMA X4500 with DX10 and HD playblack offloading support, if the wiki is anything to go by. At least they seem to understand Intel's nomenclature! But that makes two of the three G31, G33, and G35 pretty superfluous, since they supposedly use mostly similar or different variations of the same G965 design that G45 will then supersede? I had thought G35 was released, but you are also correct it has not. G45 is due at the same time as the rest of the 45 chipset launches in 2Q'08, so what is the point of launching G35 just for one quarter except to help push more parts?Sadly this does not explain P45 or X48... both of which only offer a higher official FSB rating. Suffice to say if X48 doesn't offer any improvement over X38, then why would P45 offer the same over P35. X38 is nothing more than a P35 with extra PCIe lanes, which is fine, but it makes P45 and X48 rather moot points. The goal of a business is to turn a profit, but forcing a steady stream of superfluous rebadged "new" hardware down the industry's throat is not a good thing.

Personally I really wish they dropped PS/2 altogether from new motherboards, but I find it a little odd that they included a PS/2 Keyboard port, but no mouse one.
I thought it might be a typo, but the board picture only seems to show the purple keyboard ps/2 port as well.

Intel DP35DP has a nice little bug where you get locked out of the system after doing a BIOS upgrade. All "USB Root Hub" devices fail to start; you have to delete and redetect them - but since the only way to connect mouse and keyboard is via USB, they don't work, and the only way to resolve it is to use a remote connection via LAN.Likewise, on Gigabyte GA-P35-DS3R, a Logitech G15 keyboard connected via USB doesn't function with Vista x64 boot loader - the "F8" part. A PS/2 keyboard must be used to access startup options.

I'd rather they drop an additional USB ports and keep the PS/2 ports.Why would anyone want to connect their mouse and keyboard to a USB port? It does not function better, and has higher overhead. It's kind of funny how much importance people place into ringing that last cpu cycle out of their machine, and then the nitwits put in a USB keyboard and mouse.
Guess who invented USB? Intel maybe? Why do you think Intel would want this lousy technology? Because it made people want faster CPUs. Why do we need something other than PS/2 ports for a mouse or keyboard? They don't do the job properly, and efficiently? Or wait, if we have USB ports, we can use them for something else in case we don't need to use a keyboard or mouse. Yes, that must be it! Except, how often don't you need a keyboard or mouse on a desktop machine and desperately need an extra USB port or two? Hmmmm, I'm thinking next to never.
USB is a bad, inefficient technology. For things that don't matter like cameras, it doesn't matter (naturally). For anything else, you've made a compromise you probably shouldn't have made. It sucks for hard disks, it sucks for mice and keyboards, although it's good for powering portable refrigerators ( http://usb.brando.com.hk/prod_detail.php?prod_id=0...">http://usb.brando.com.hk/prod_detail.php?prod_id=0... ). Maybe that's what it should be used for. Everything else pretty much has a better choice of an existing interface.

Yes, let's keep the PS/2 keyboard and mouse connections. I have a KVM that I don't want to replace and a mix of systems across time. The latest edition is a MB with PS/2 keyboard but no mouse. The first PS/2 to USB converter was trash. The 2nd one works better but still the mouse hangs up without warning at the darndest times.At slightly off the topic, it seems that Intels dropping of IDE/PATA was a bit premature as all the MB manufacturers have to add back a JMicron (or someone elses) chip for IDE hard and CD/DVD drives....

Absolutely. There's nothing worse than having the Mobo not like your choice of USB keyboard and refuse to recogize F-Keys or Del upon boot. PS/2 is reliable, and has no disadvantages over USB that I can think of for keyboards. I think I heard something about precision mice that seemed to favor USB, but I've never had an issue with using my PS/2 connector with my USB mouse (till the adapter broke due to leverage issues). My mouse is now plugged in via USB and I don't feel any more precise or that my mousing has improved.USB is a hellspawn of a standard, and I wish that Firewire would have taken off instead. Some will blame Apple for the licensing garbage, and maybe that is true, but Apple's first iMac had USB and no Firewire. That is when USB really took off. Meanwhile, much like PS/2, ADB (the bus used for keyboards and mice on old Macs) was a better standard, and many complained about the USB keyboards not keeping up with typing, and of course the old keyboard combinations did not work as well, due to a lack of hardware interrupt, I think. No more rebooting from the keyboard when locked up, force quit didn't always come up. Lots of issues.
Back to this board, I see they put FW400 on it, but felt that for $230, the customer should pay for their own FW800, even though it has been out for 4 years. Some premium.

rants aside, keeping the PS/2 keyboard connector is an good idea as it allways works as with windows that is an slight chance that the usb kayboard may not not of been detected yet or you mate be stuck with the found new hardware box but unable to press enter hehi still use an ps/2 keyboard and an usb mouse so works well as it is

oops sorry was posted during final edit, it's all fixed now...
