| BIOS Revision: | v.F4 |
| Board Revision: | v1.00 |
Gigabyte has provided a very comprehensive BIOS that is enthusiast oriented in the latest F4 release. In our opinion, Gigabyte continues to annoy the crowd that will buy this board by insisting on using the Ctrl-F1 sequence to open up the additional performance oriented BIOS settings. We were able to match most BIOS settings on the ASUS P5K when tuning the board. The most important option to change is the Performance Enhance setting from Normal to Turbo. This will improve memory performance in much the same way as the Transaction Booster from ASUS, although the level of fine tuning does not match the ASUS board. We found the Extreme setting to be just that, extremely on the edge as we could not complete our benchmarks when using it. We measured Vcore droop to be around .03V under load testing with our QX6700.
Gigabyte GA-P35-DQ6 Board Layout and Features

Gigabyte provides the user with a good layout considering the massive heatsink system employed on this board. This board features a twelve-phase power regulation system and 100% use of conductive polymer aluminum capacitors that provided excellent stability during testing at stock and overclocked speeds. During our overclocking tests we found the massive heatpipe system worked well but additional airflow was required to ensure stability during overclock testing. However, our larger heatsinks such as the Scythe Infinity barely fit and were difficult to install. The cooling backplate on the bottom of the board requires removal or the use of longer screws to attach coolers that require a backplate mount.
The P35-DQ6 installed easily into our Cooler Master CM Stacker 830 case and cable management was very good for power, optical, and hard drives although the 8-pin ATX connector was a tight fit due to the heatpipe system. Unlike the ASUS P5K series, Gigabyte took a more legacy approach with the rear panel options. The standard PS/2 mouse and keyboard ports, parallel, and serial ports are included compared to ASUS only including a PS/2 keyboard port.

X38 is basically ready, going through some fine tuning now... I understand it will be held until after the 1333CPUs are launched and DDR3 availability is a little more widespread/cost effective. I expect late August right now, but you never know with Intel. ;-)JarredWalton - Monday, May 21, 2007 - link
Technically Q3 is any time between July 1 and September 30, but if they're saying Q3 right now it probably means some time in August at best.gigahertz20 - Monday, May 21, 2007 - link
I applaud ASUS for only including 1 legacy connection on their P5K series, and not 4 like Gigabyte has chosen to do for their P35 board. Death to legacy connections!I mean really, why even include those damn legacy ports. The enthusiast that buys one of these boards will not be using them, they are a waste of space. Instead of having them, they should replace them with more USB ports or something useful.

I still have a parallel based laser printer that works fine for what I need, and I'm quite happy using it until it dies. There are also people that use serial devices that cost a lot of money. I don't think every board needs legacy support, but it's good that there are still options for people that *need* certain legacy devices. I've got several KVM switches that won't be useful if PS/2 ports disappear. :(yacoub - Monday, May 21, 2007 - link
Don't they offer USB or eSATA to serial/parallel convertors for those sort of situations? :)JarredWalton - Monday, May 21, 2007 - link
Sure, but I haven't had the need to try one yet. :)Truth be told, my printer has a USB port, but it behaves very poorly using a USB connection. It's a Brother HL-1240, and if the printer isn't powered on when you boot, Windows won't see it unless you unplug it and plug it back into a different USB port. It just works better with LPT, and as I said for my needs it's sufficient. The way I figure it, having the ports there isn't hurting most people. I've never seen anything to indicate they hamper performance, and how many extra transistors are "wasted" on these ports? Maybe a few thousand? Heheh. 45M transistors on the P35 is a bit crazy....
For what it's worth, between mouse, keyboard, and my LCD (which actually has four USB ports and flash memory readers), I haven't had any need for more than four USB ports on a motherboard. But then, I've got too many PCs around anyway.

I agree with you, but for another reason.I don't like USB at all, because a few years ago I ran some tests, on motherboards ranging from MVP3 based to a KT880, and USB seems to have a negative impact on performance, particularly on memory, in many cases.
It doesn't make my keyboard work any better, or my mouse, and I'm not sure why I need it for those functions at all. PS/2 ports don't do it well enough? I'm not crazy about this one size fits all approach, especially when it comes with overhead. The current ports work fine.
USB is a crappy, bloated technology. I'm not sure the "S" should stand for "serial" at all, I think there is a better word that begins with S for it.

Wake me up when Bluetooth works over PS/2.Though one reason to still include PS/2 keyboard/mouse is that it is hard to screw up support for those in Linux kernels. Same can't be said about USB.
TA152H - Tuesday, May 22, 2007 - link
Wake me up when I need Bluetooth.You could implement Bluetooth easily if USB didn't exist, but you're missing the point anyway. When you have to use USB for stuff that is handled more efficiently by PS/2 ports, it's a bad thing. Or other ports. It adds no function for these devices, and comes with overhead. It's a bad idea, but of course Intel was in the mode of making as many things as possible use CPU power so they could keep selling their latest and greatest.
It's just a rehash of some dorky Apple stuff that most people here don't remember. The original MacIntoy didn't have any slots, and you'd attach stuff to some serial bus for expansion. Naturally, it didn't work out, and they had to add slots. At least they didn't get rid of slots for USB, they just made it bloated.

Man, if the P35 boards are going to be around the $250 mark, I'm not looking forward to see the price on the X38 boards.... :-(
