The Epox EP-MF570 SLI will automatically split the PCI
Express x16 bus equally between the two physical PCI Express x16 slots if both
are populated, so in effect each card get 8 PCI Express lanes in SLI. When just
one videocard is used (in the orange slot), it receives the full 16 PCI Express
lanes. The nForce 570 SLI chipset generates a moderate amount of heat and is
cooled with a small heatsink fan combo. It's replaceable however the default
connector is two pin type.
One thing I'm happy to see all motherboard manufacturers
implement is switchless SLI. Early Socket 939 nForce 4 SLI based motherboards
required jumpers or a selector switch card to be moved, but all socket AM2
nForce 570/590 SLI motherboards automatically sense when a second videocard is
inserted meaning this step is no longer necessary for the user.
nForce 570 SLI Chipset
nVidia's AMD socket AM2 supporting chipsets include the
nForce 590 SLI for enthusiast class users, the nForce 570 SLI for high end
gamers, nForce 570 Ultra for mainstream gamers and the nForce 550 for the rest
of the mainstream market. The nForce 570 SLI offers the best of both worlds, and
coincidentally it's the chipset the Epox EP-570 SLI motherboard is built

Each offering in the nForce 500-series adds many
completely new features into the mix. Take a quick look at the chart at left to
see what the nForce 570 SLI brings to the table. In brief, the nVidia nForce 570
SLI and 570 Ultra socket AM2 chipsets share a similar feature set to the nForce
550 MCP, all of which are more mainstream solutions with good cost to value
Both are single chip solutions with a total of 16 PCI
Express lanes devoted to the videocard sub system, however the nForce 570 Ultra
only supports one videocard while the nForce 570 SLI naturally supports two. The
PCI Express x16 bus is split in half when SLI is configured on the Epox EP-MF570
SLI, so each videocard receives eight PCI Express lanes.
There are an additional four PCI Express x1 slots and
five PCI slots for expansion purposes.
Both 570-class chipsets have dual Gigabit Ethernet which
includes nVidia's DualNet technology as well as its FirstPacket which permits
packet prioritizing. There is one IDE channel, six SATAII connections (RAID
modes 0, 1, 0+1 and 5 inclusive), and 10 USB 2.0 devices along with Intel's 7.1
channel Azalia high definition audio option.
Now that we've had a chance to touch upon some of the
features of the Epox EP-MF570 SLI let's walk through the photo gallery of this
board before jumping into the overclocking, the BIOS, and PCSTATS set of office
oriented and gaming benchmarks.
