X48 Motherboard Comparison

Accessory RAID Controller Performance

All tested motherboards included a third-party Ultra ATA/SATA controller with RAID capabilities, which the majority of users will connect to a DVD or CD optical drive. Yet many of the boards provide External SATA connections through the added-in controller, and a few might want to use eSATA for backups. Thus, the man upstairs (no, the other man upstairs) demanded that we gauge the performance of each system's third-party controller in the highest-bandwidth configuration: RAID Level 0.

Access times might not be very important for mass storage or optical drives, yet the test is part of the H2benchw suite. Those interested will find that all four add-in controllers are roughly equal to Intel's integrated ICH9R controller in this test.

The ICH9R transfers data at significantly higher speed than any of the third-party controllers, even though the added-in parts all sit on a PCI Express interface that affords up to 250 megabytes per second bandwidth in each direction simultaneously. The Gigabyte and Asus controllers are both supplied by JMicron, so the similar results were expected.

The JMicron JMB363 controller of the Asus P5E3 Premium somehow manages to approach the performance of the integrated Intel ICH9R controller in H2benchw's Read Transfer Rate test.

Asus and Gigabyte's write transfer rates are nearly identical in H2benchw, which is unsurprising given the similar (or possibly identical) technology. We're still trying to figure out how Asus pulled off the huge gain in H2benchw read transfer rates, however.

    Help please.Can this board be configured with the first two (SATA) HDs mirrored and the other drives JBOD? Thank you in advance.

    Great review, very detailed and informative. But I must say that either you were lucky that your X38 P5E3 Deluxe came with a better-than-average chipset or that I wasn't so lucky and got a malfunctioning one.

    I have an Asus Maximus Formula which is, as you know, the Republic of Gamer's solution for the X38 and recently bought a Patriot Extreme Performance 1150mhz PC2-9600. Whenever I try anything above 1020mhz for the RAM my PC reboots; the higher it is the less time it takes to do it. At 1020mhz it'll only reboot if I run something more demanding like 3dMark06 or any new game, at 1100mhz it'll barely show the Windows loading screen then reboot, above 1120mhz it'll not even load windows and freeze. But in every case it boots up fine.

    The Asus forums are full of users who can't get stability in any way with >=1066mhz ram on X38 boards. A selected few have come to accomplish it however, which leads me to think those were the lucky ones who got the good shipment, like you. The Patriot forums are the same, X38 users can't get their system stable with RAMS over 1066 or not even that.

    Maybe that X48 "official" support is something to consider, it might be the fix to the X38 we users are looking for. Even if it's only to make sure it'll run RAMs at >=1066mhz, it's good enough already.

    oblivionspell - Have you tried manually setting your RAM voltage to the correct value for the performance setting(s)?

    I had to do this on my Asus Crosshair, even though EPP is supposed to take care of it for you. Without manually setting the voltage, I had memory corruption and crashes, but could use the non-EPP mode. With the voltage bumped to the correct 2.1V,
    the EPP modes work perfectly.

    It's just a matter of having the right RAM and using the correct timings and voltage. All X38 and X48 motherboards that support DDR2 memory can run DDR2-1066 speeds with stability, so long as the RAM is set up right in BIOS.

    "Inside, users will find a GUI based on the Smart Common Input Method (SCIM) platform."

    This is not accurate. SCIM is an "input method" -- a scheme for entering internationalized text. Not sure what the GUI is really based on. GTK2, maybe?

    I see your point, but that's the same arguement as "Windows 98SE is a GUI based on DOS". Which is innacurate only in wording. It would be better to say "Windows 98SE is a GUI for DOS".

    So, you'd be happier to read "Users will find a GUI for the Smart Common Input Method (SCIM) platform" correct?

    It's not only the wording. SCIM is not an operating system, so even your example is not analogous (won't even mention that DOS and Windows are separate operating systems with distinct kernels, etc).

    This statement is as correct as saying Vista has a GUI based on a 105-key keyboard.

    SCIM is an input method platform independent on the GUI. GTK GUI is an widget toolkit, independent on SCIM (although they *may* used each other). Neither is "based" on the other.

    If you want to emphasize that the Express Gate supports users of many different languages and nationalities you can mention that the GUI USES SCIM.
