Tyan samples 64-bit Xeon mobos

Tyan has followed the arrival of Intel's 'Nocona' 64-bit capable Xeon DP chips with four motherboards geared up to support the new processor.

Two products - the Thunder i7520 and Thunder i7520R - are based on Intel's 'Lindenhurst' E7520 chipset and are aimed at tower and 1U rackmount form factors, respectively.

Both provide two Gigabit Ethernet ports and can offer Serial ATA or SCSI Raid support depending on customer requirements, the company said. The i7520 supports up to 32GB of registered 333MHz or 266MHz DDR SDRAM, while the i7520R can take up to 16GB memory. Both offer PCI-X for expansion, but the i7520 also includes a PCI Express x8 slot and an old-style PCI connector.

The ATX form-factor Tiger i7320 and its 1U rackmount sibling, the Tiger i7320R, both use the lesser-specced 'Lindenhurst VS' E7320 chipset. Again there's support for 32GB of registered 333/266MHz DDR SDRAM (the i7320) or 16GB of memory (the i7320R), PCI-X support and, in the i7320, legacy PCI provision. Both mobos ship with a pair of Gigabit Ethernet ports on add-in PCI Express boards.

The new boards provide support for Nocona's AMD64-like 64-bit x86 extension technology, EM64T, along with the CPU's 800MHz frontside bus. Their release follows Tyan's announcement in June of the Xeon DP-oriented Thunder i7525 which supports the 800MHz FSB, but not EM64T.

Pricing was not disclosed, but Tyan said all four motherboards are sampling now and will go into volume production later this month. ®
