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.

Wireless works yes. They are linked up through the base and work in dos mode. Both RF, and bluetooth meese work.kilkennycat - Monday, December 10, 2007 - link
I notice from the board picture that the rear mounting holes are still in the corners of the board, so if the WIDTH is 4cm more than the standard ATX, does the board need special mounting ? I assume that WIDTH means the distance across the edge of the board in contact with the rear of the case. Please correct if my assumption is wrong.Rajinder Gill - Monday, December 10, 2007 - link
THe width is the length across the top edge of the board. Screw hole spacing is still standard ATX, just that this board over-hangs by a few cm (the Sata port end will protrude further into your case) ...regards

As yes, you actually mean DEPTH of course, if referencing tower case dimensions (Height x Width x Depth). So any case wishing to accommodate this board needs to have at least 4cm DEEPER front to rear clearance for the motherboard, nothing to do with it being a mid-tower or full-tower. Am I right?Might also preclude using this MB in those cases having the motherboard mounted on a slide-in ATX tray ( a great feature, btw ), as they may have a lip or other registration hardware on the leading-edge of the tray.

What size are they? I cant find it here, or on Asus's site. They look like 1/4 inch - which kind of sucks.Rajinder Gill - Monday, December 10, 2007 - link
The fittings are 1/4", but ASUS does provide adapetrs to use 1/2 tubing..Raja..

thanks... bummer. 1/4 restricts my flow.
