Epox MF570SLI: Basic Features & Board Layout
The nForce 570 SLI is targeted by NVIDIA at the mainstream market. As such, it is fair to expect that 570 SLI boards will normally offer fewer features than 590 boards. The distinction is somewhat artificial, since the 570 SLI is a simpler one chip solution, but it supports dual X8/single X16 instead of the dual X16 supported by the 2-chip 590 solution. What we mean by artificial is the fact that you will be hard pressed to find any real evidence in today's market that dual X16 SLI can outperform dual X8 SLI. This distinction may exist in the future, but it is just not a reality with today's top graphics cards.
At this time, Epox is not manufacturing a 590 chipset motherboard, and they are to be congratulated for providing a very wide range of overclocking options and board features for their mainstream MF570SLI. This is a board that should sell very well based on an outstanding feature set, good overclocking options, and the kind of added value Epox often delivers on their recent boards. You even get an LED readout much like high-end DFI and momentary switches for mounting outside a case, just like the Foxconn 590 SLI board.
Overclocking options are exceptionally complete, and were it not for boards like the ASUS M2N32-SLI and the Foxconn 590 we would be singing the praises of the Epox BIOS options. As it is Epox manages to provide a DIMM voltage range of 1.8v to 2.5v, but without the fine adjustments found on the ASUS. About the only missing feature is Firewire, which will matter to some, but can be easily added with a card.
A VERY important addition for many will be the JMicron 383 SATA2 RAID chip. Not only does it add two additional SATA2 ports (total 8), but it also adds a second IDE connector for 2 additional IDE devices. Those who point out that Intel and NVIDIA have made optical drives a nightmare with the forced use of SATA optical drives that generally don't exist will be happy to see a manufacturer that listens to what they want.
Epox has been using a striking green and off-white oversize package lately, and the MF570SLI continues that new packaging. Not only is the box oversized, but it is crammed with all the round white cables you will need, white SATA2 cables, and a power pack with manuals, disks, heatsinks for a number of small chips, and a temperature measuring cable that attaches to the motherboard.
Epox uses a slick 4-phase board design with modular coils that certainly look very attractive compared to the manual wind coils often seen on motherboards. Layout of the green Epox motherboard is an area that generates very mixed feelings, however. The 24-pin ATX connector is smack in the middle of the board. Snaking the bulky power cable is difficult and there is danger of impeding air-flow to the CPU. We understand from discussions with manufacturers that a mid board power connector, near the PCIe slots, makes it easier to manage power to the PCIe slots, but this location is not an easy one for many case designs. The 4-pin 12V connector is better located at the top board edge.
The extra IDE connector is very welcomed, but its location, along with the floppy connector, at the bottom of the board makes it a difficult reach in some case designs. If you're using big video cards you will have trouble routing the second IDE and floppy ribbon. Thankfully the 8 SATA2 ports are thoughtfully located out of the way of video cards - even in an SLI installation.
With two double-width video cards like the 7900GTX, there will still be one usable X1 PCIe and two usable PCI slots. With standard width video cards in SLI mode you pick up a second X1 PCIe and an extra PCI slot. The two PCIe X16 slots are separated by three slot widths, which will make exotic video-cooling workable in most cases.
For a mainstream price you still get both Optical and Coax S/PDIF connectors, dual Gigabit LAN, PS2 keyboard and mouse connector, 4 USB, and six programmable mini-jacks for HD audio. Audio is powered by the Realtek 883 codec. You will not find serial or parallel ports on the rear. If you need Firewire you will have to add it.
While the layout could definitely be improved, once the Epox was installed it was exceptionally stable and trouble-free during out testing. Epox also covers potential BIOS flash problems with their Ghost BIOS feature which allows recovery from most "bad flash" situations.

Asus opted to design for PCI access. With SLI using dual-width video cards there are still two PCI slots available, but the single x4 PCIe is covered. With single-width cards in SLI 3 PCI and an x4 PCIe are available.MacGuffin - Thursday, June 29, 2006 - link
The picture of the motherboard on Newegg is different: the AT review shows a PCI slot above the black PCIe x16 slot...but the retail board at Newegg has a PCIe x1 slot. Except for that, everything else looks identical. Are there two versions of this board floating around? One with 3 PCI/1 PCIe x4 and the other with 2 PCI, 1 PCIe x4 and 1 PCIe x1?Wesley Fink - Thursday, June 29, 2006 - link
There are 2 versions of the board - with WiFi and without. The retail version we tested was WITH WiFi built in.
