Powerful Server Board

Scott S., Newegg
15 January 2010
  • Summary: This board has two "Northbridge" IOHs, but you do not need to worry about PCI Bus Addressing like on other server boards with dual Northbridge chipsets- the two IOHs have QPI links to each other, so they basically pretend to be one massive IOH.
  • Pros: This is a powerful server platform with lots of flexibility. The price is there, too. For the features you can't beat this board bang-for-buck. All 4 x16 slots are fully populated- a welcome feature on a server/workstation board. With two E5520s, I just cannot slow this box down, no matter how ha...
  • Cons: Not a con. I had a problem with a pair of GTX 260s under Linux on this board which turned out to be an addressing issue.

  • Pros: 1) Dual Tylersburg chipset for massive PCIe bandwidth. Every x16 slot is fully electrically populated!!! 2) Dual-socket Nehalem support, fits in standard SSI/EATX cases. Very few boards do this combined with (1)--SuperMicro's offerings certainly do not. This fits perfectly within a Silverstone Te...
  • Cons: 1) Onboard GigE is Intel 82574L. In contrast, the 82576 NIC used on comparable SuperMicro boards supports better I/O virtualization. Not a big issue unless you're running with a VM hypervisor though. 2) Onboard audio (Realtek ALC262) is almost worthless. No fixed audio jacks in the rear (apparent...
