Intel Corporation announced plans to release a yet another revision of its server chipsets E7320 and E7520. The new stepping may help the company to cure certain alleged glitches of its new chips.

Intel’s recently released E7320 and E7520 chipsets originally code-named Lindenhurst are designed for servers based on 2-way Xeon processors with 800MHz processor system bus and EM64T. The chipsets support dual-channel DDR or DDR2 SDRAM memory with ECC and with PCI Express x4 or x8 add-in cards, such as network adapters or RAID controllers. Intel currently offers specially designed LAN and RAID controllers with its E7320 and E7520 chipsets. The difference between Intel’s latest server chipsets is in the number of PCI Express x8 links (each x8 can be configurable as two x4s): the E7320 sports only 1 x8 link, while the E7520 sports 3 x8 links.

Some sources earlier this month said that current revision of E7520/E7320 chipsets may not work properly with certain adapter cards and added that the flaw will be corrected in the next hardware stepping of the new chipsets.

Currently Intel is readying C4 stepping of E7320/E7520 memory controller hubs. The C4 stepping is pin-to-pin compatible with the C2 and does not require any mainboard modifications. Design changes have been made to the MCH C4 and will require customers to perform re-qualification and may require BIOS change, Intel said.

Earlier this year Intel updated C1 revision of Lindenhurst with C2 revision of Lindenhurst memory controller hub.

Representatives for Intel did not comment on the story.
