MSI X38 Diamond  (Source: MSI)
Expect Intel's high-end chipset to show up next month

Intel officially set its performance embargo on its upcoming X38 Express chipset for September 23. Motherboards based on the X38 Express chipset should show up in retail in early September, according to motherboard vendors. The September 23 non-disclosure lift date only applies to reviews and performance numbers for the X38 Express chipset. The situation will be similar to the P35 Express chipset launch, where motherboards were available before its Computex 2007 launch announcement and NDA lift date.

The new chipset is a member of the Bearlake family, which saw its initial debut with the G33 and P35 Express variants last June. Intel’s X38 Express succeeds the 975X Express that made its debut with Intel’s Pentium D Presler processors. Although the Intel 975X Express launched in late 2005, the chipset shared basics with Intel’s 945 and 955X Express chipset families. Intel decided not to refresh the 975X Express with a Broadwater variant and held out for Bearlake.

Intel’s X38 Express introduces PCIe 2.0 support to the LGA775 platform. PCIe 2.0 offers greater bandwidth over the existing PCIe standard – up to four gigatransfers per second, or GT/s, with the 20% encoding overhead accounted for. The chipset also supports dual full-speed PCIe x16 slots for ATI CrossFire multi-GPU technology. Intel guidance does not show any indication of support for NVIDIA's SLI Technology.

Officially, the Intel X38 Express chipset only supports DDR3 memory. However, motherboard vendors disagree and intend to release X38 Express based motherboards with DDR2 memory support. Motherboard manufacturers such as DFI, Foxconn, Gigabyte, MSI and others had DDR2-compatible X38 Express motherboards on display at Computex 2007. The DDR2-compatible solutions were either DDR3 and DDR2 or dedicated DDR2 supporting motherboards.

Expect motherboards based on the Intel X38 Express to pop up in retail next month. DailyTech estimates the cost of entry around $200 for a no-frills board and around $300 for boards that include a kitchen sink in the package.

There's no mention of SLI support from any of the vendors. The same rumors popped up for the 975X Express as well. Nothing ever came through.

Sadly it looks as though the "SLI on X38" thing is just a mirage. There was what looked like good evidence for it at one point - some motherboard manufacturers actually advertised their X38 boards as supporting SLI at this year's Computex.

But sadly it seems this was a misunderstanding.

There is, of course, absolutely no technical reason why X38 cannot support SLI; Nvidia has simply decided to screw Intel-chipset customers by disabling SLI support in its drivers unless you're using an Nvidia chipset motherboard. Nvidia could easily choose to switch SLI on for X38 boards in any new driver release, but they won't because they want to sell more Nvidia chipsets. (I'm constantly puzzled as to why this isn't a violation of competition laws).
